Í (ol. «r9-_7) This invention relates to glass working ma chines and has particular reference to a machine adapted to produce changes in the shape oi glass tails of the chuck structure and the actuating means therefor; Fig. 12 is a front elevational view of one of, the chucks; 5 tubes or like bodies. ` - While the machine may be conveniently used for the forming of ampoules and will be so de scribed, it will be apparent that the machine may be utilized for forming Various types of bodies from glass tubes or the like. One of the primary objects of this invention 10 is to provide an improved feeding means for feed ing blanks to a machine of the above mentioned character. . A further object of the invention is to provide 15 improved chucks for gripping the blanks during the forming operations. -v - The invention contemplates further th'e pro vision of means for heating the blanks and forv so rotating the chucks ‘that the blanks will be ` 20 rotated and evenly heated by the heating means. The invention provides means whereby a plu rality of constrictions or the like may- be formed at spaced points.through the length of a 'glass tube and provides further improved means for 25 severing the glass tube into a plurality of sec tions after the forming 4operations are completed. The above are merely a few of the numerous objects of lthis invention which will become more apparent as the following description proceeds 30 particularly when reference is had to the accom panying drawings wherein: ’ Fig. 1 is a side elevational view of a machine constructed in accordance with the teachings of this invention; Fig. 2 is a rear elevational view partly in sec tion of the machine shown in Fig. 1; Fig. 3 is a fragmentary side elevational view of the feeding mechanism; ’ ` .

General structure of the machine AThe invention is illustrated as being embodied in a machine of the type shown in Patent Number> 1,621,359 issued to John T. Fagan et al. on March 15, 192'7. The machine is illustrated inthe draw ingsl wherein like reference characters designate' corresponding parts throughout all views, as com prising a base 30 which carries the upwardly ex tending bearing standards 3l and` 32. Likewise carried by the base and projecting upwardly therefrom are circular housings 33 and 34. These housings are disposed between the bearing standards but are spaced apart as clearly illus trated iny Fig. 2 of the drawings. Journalled in -the standards 3l and 32 and projecting through the housings 33 and 34 is a shaft 35 to which are secured chuck carrying drums 36 _and 3l. The drum 3B is disposed within the housing 33’while Fig. 4 is a fragmentary front elevational view ‘ the drum 3l is spaced from the drum 36 and is 40 40 kof the feeding mechanism; i Fig. 5 is a fragmentary detail sectional view of a portion of the mechanism shown in Fig. 3; Fig. 6 is a fragmentary elevational view of the chain structure forming a part of the feeding mechanism; Fig. '7 is Cn the line Fig. 8 is 4on the line l - a sectional view taken substantially 'l-l of Fig. 6; a horizontal view taken substantially 8--8 of Fig. 3; Fig. 9 is a detail sectional Aview through a part of the magazine forming-a part of the feeding `mechanism; Fig. 10 is a fragmentary sectional view showing the chuck actuating and driving means; Fig. l1 is a sectional view'showing further de disposed within the housing 3i it being under stood that upon rotation of the shaft 35 the drums are rotated within their respective hous lIlgS. The drums are similar in construction and therefore only drum 3% is illustrated in detail in Fig. 2 ofthe drawings. By reference to this fig ure it will be noted that the drum comprises a hub it which is suitably fixed to the shaft 35 and spaced disklike members @il projecting radially from the hub. The drums 33 and 3l are prefer ably secured together by tie members it.’ as illus trated in Figures 2 and 17 of the drawings. For rotating the shaft 35, there is provided a variable speed motor i5 which through reduction 55 2 2,125,017 gearing 46 drives a sprocket 41. This sprocket from‘the magazine, which will later be described, and locating the blanks properly with reference drives a chain 48 which in turn drives a sprocket 49 ñxed to a shaft 50 which is disposed at one side of the machine. The shaft ‘50 carries- a worm to the lugs on the conveyor chains 12, notched disks 85 and 86 are mounted on the lower sprocket shaft 10. Two of these disks are associated with 5I which engages a worm wheel 52 on the shaft 35 for rotating the latter. The drums carry chucks 'each lower sprocket wheel 1I and the method of ‘ 55, these chucks being mounted for rotation and adjustably attaching these disks to their respec for axial movement as will hereinafter bev more tive sprocket wheels is illustrated in Figures 3 fully described. There are a series of chucks on and 5 of the drawings. each drum and the chucks of one drum are aligned with the correspondingchucks of the other drum to the end that each pair of chucks may grip‘opposite ends of a blank to be shaped such for example, as a length of glass tubing. Blank feeding mechanism In the operation of the machine it will be under stood that lengths of glass tubing are fed to the chucks and are carried in a circular path by r0 tation of the drums 36 and 31.' In the machine disclosed in Patent Number 1,621,359, the lengths of glass tubing were fed into alignment with the chucks by virtue of notched disks disposed be tween the rotating drums. These disks limited the area of the glass tubes that might be heated and further made it substantially impossible to I form but a single constriction centrally of each glass tube. _ The present invention contemplates the pro vision of feeding means disposed to one side- or in front of the machine to the end that the space between the drums will be clear with the result that glass tubes held by the chucks may be heated Vat any point throughout their lengths. The feed ing mechanism is shown more particularly in Figures 3 to 9 inclusive, but reference should be made ñrst to Figure 1 wherein the drive for the feeding means is illustrated. It will be noted that the shaft 50 is extended 40 beyond the worm 5I and that adjustably secured to the end of this shaft as by the- clamping collar ' 60 is a bevel gear 6I which engages a bevel gear 62 on a shaft 63. The shaft 63 carries a pinion |54- which engages a gear 65 ñxed to one end of 45 `a shaft 66. This shaft extends across the front of the machine as illustrated in Figure 4 of the 50 55 60 65 _ Thus, "i'o'r example, to the outer face of a 10 sprocket wheel 1| disk 85 is secured by bolts 81. These bolts pass through relatively narrow arcuate slots 88 formed in the disk 85 whereby the disk 85' may be adjusted rotatively with reference to its respective sprocket wheel 1 I. 15 Disk 86 is adjustably secured to 'the outer face of its respective disk 85 by bolts 89. These bolts pass through the slots 88 in the. disk 85 and also through arcuate slots 90 in the outer disk 86, the heads of these bolts engaging the outer face of the disk 66 to clamp the same in position as will be apparent'. - The arcuate slots 90 permit rotative adjustment of disk 86 with reference to disk 85 by loosening of bolts 89. Further, the slots 90 are relatively wide as Vcompared to the slots 88 and as compared also to the heads of the bolts 81, with the result that the heads of bolts 81 may move in the slots 90 as clearly illustrated in Figure 5 of the draw ings. ` 30 The disks 85 are notched as at 95, while the disks 86 arenotched as at 96. The notches 95 and 96 are adapted to receive the glass tube blanks and the sizes of these notches may be adjusted to adapt the disks to the feeding of tubing of 35 different diameters. Thus only one piece of tubing may be received in the aligned notches at a time. The glass tube blanks are fed to the disks 85 and 86 from a magazine |00. This magazine comprises side plates I0| carried by brackets |02. mounted for longitudinal movement on a sup porting rod |03 whichl extends across the front of the machine. The adjustment of the brackets |02 longitudinally of shaft |03 provides that the 45 drawings and carries intermediate its ends< side plates may be spaced apart a distance equal to the lengths of the pieces of glass tubing being sprocket wheels 61. There are two sprocket processed. _ wheels provided, these being spaced however, The floor of the magazine is formed of bars closely together and being disposed in align |05 supported in spaced relation to each other by ment with the center of the space between the brackets|06 carried by the shaft |03 and adapted drums 36 and 31. , 'I'he shaft 66 is journalled in suitable bearings for adjustment longitudinally thereof whereby the bars may be moved toward and away from 68 carried by the housings 33 and 34 and jour nalled` in similar bearings 69 carried by these each other. The inner ends of the bars are sup housings is a shaft 10. This shaft is spaced a ported by brackets |01 carried by a shaft |08 55 which extends across the front of the machine in substantial distance below the shaft 66 and car ries the sprockets 1I, there being two of these parallel relation with respect to the shaft |03. The inner ends of the bars |05 are arcuate sprockets which `are in alignment 4with the sprockets- 61. Conveyor chains '12 are trained shaped to extend around the lower side of-sprock over the sprockets l61 and 1| and are driven by ets 1I. Adjustably secured to the free inner the sprockets 61 asvwill be clearly apparent. ends of the bars |85 as by slots III formed in As illustrated Ain Figures 6 and '7 of the draw these bars and bolts II2, are guide arms or rails ings, each sprocket chain comprises links 15 piv ||3 which extend upwardly in the rear of the otally secured to spaced blocks 16. Secured to sprockets 61 and 1I. These guide rails have por every third block as by a screw 11 is an angle lug 18, the portions 19 of which are adapted to engage the glass blanks as will later be described. The next succeeding chain block 16 carries a pin 80 which projects through a slot 8| formed in the adjacent lug with the result that the lugs may not turn about the' screws 11 but'are allowed clear ance for slight rocking movement as the con veyor chains turn about the sprocket wheels.

The glass tube blanks II5 are stacked in the magazine as clearly illustrated in Figure 3 of the drawings and by virtue of the downward inclina tion of the bottom rails |05 these blanks are fed 75 3 2,125,017 The chucks and the actuating means therefor~ toward the conveyor chains and the feed disks. For the purpose of preventing `the lugs on the As previously mentioned, the drums 36 and conveyor chains from breaking the blanks, guard l 31, each carry a series of chucks.

As pre 35 35 viously mentioned, the ‘ portions ||4 of these \guard rails parallel the path of `travel of the chucks 60 so that the tube blanks are caused to travel along a path which lies between and paral lels the path of travel of the chucks. With the 40 jaws of the chucks open as will 'be later de scribed, the chucks are moved inwardly and caused to grip the ends of the tube blanks before the blanks have passed beyond’the guide rails H4. As previously mentioned, the notched 'disks may be adjusted for tubes' of diiîerent diameter by adjusting one notched disk with reference to For the purpose of forcing the arms Ml away from each other againstthe force exerted by springs |42 there is provided a frustro conical member |45 carried on the end of a rod |46 which extends through the tubular stem |36. A spring |41 disposed within stem |36 and surrounding 40 rod |46 engages a shoulder |48 on the stem |46 and engages at its other end a collar M0 carried by the tubular stem |36. Thus this spring tends to force the frustro conical head |45 forwardly so that the gripping jaws are resiliently urged to 45. ward their gripping position. Since the jaws are frictionally secured to the shafts |38, it is desirable tof provide some means be properly timed with the chucks on the rotat ing drums by adjustment of the bevel gear 6| with , for centerng these jaws with reference to the axis reference to the shaft 50,-this adjustment being of ‘the housing |35. For this purpose the outer 60 50 afforded by the adjustable collar 60.A The notches face of the housing is provided with an opening |50 adapted to receive a pin |5| shown in dotted may be adjusted with reference to the lugs on the conveyor chains by virtue of the bolts 81 which lines in Figure 11 of the drawings. It iscontem pass through arcuate slots in the disks 85. Thus plated that in `adjusting the jaws the pin will be . 55 the other. >The lugs on the conveyor chains may it will be apparent that glass tubes picked up by the notched disks will be properly located with reference to the lugs on the conveyor chains and will be carried by these lugs into proper position ~ to be gripped by the chucks on the rotating drums. “0 , rt might be ynoted that the guard raus Hs are preferably provided with c_ams |25 to prevent bridge building of the glass tube blanks. Fur I ther, there is provided means operable to prevent feeding of the blanks from the magazine, this means comprising arms |26 pivotaliy secured to the outer ends of the bottom rails |05. The inner ends .of arms |26 are provided with upward pro jections |21 which when the arms |26 are rocked 70 upwardly pass between the tube blanks and the- secured in position and the jaws forced to their gripping position into firm engagement with the > pin. For actuating the chuck jaws, that is to open vthe same during a portion of the rotation of the ‘ drums 36 and 31, means is provided for moving the stern |46 to the right asv viewed in Figures 10 and 11 of the drawings. As illustrated. the rod |46 is-extended beyond the tubular stem |36 and l has secured to its end a sleeve |55. Clamped on the sleeve is a collar |56 grooved to receive a yoke 65 |51. - The yoke |51 is carried by a sleeve |58 and rotatably carried by this sleeve is a roller |59. This roller projects radially outwardly from the drum and is arranged to engage a cam |60 which 70 notched disks thus preventing feeding of the is secured to the -cylindrical housing in which the blanks to the disks. Cams |28 ñxed to a shaft |29 adapted to be rocked by a suitable lever (not shown) are provided for rocking the arms |26 up drum is located. The cam |60 is so constructed wardly. that during a predetermined portion of the rotation of the drum the sleeve |58 andxthusfthe yoke |51 is moved to the right as viewed in- Figures 1.0 4 . 2,125,017 and 11 to thus withdraw the frustro conical head |45 from between the arms |4| permitting these arms to be drawn together by the springs |42 which effects an opening of the jaws |39. It will be apparent that the cam |60 may be so arranged that the gripping jaws of the chuck will be opened at any desired point or points during the rotation of the drums. ' _ For the purpose of guiding and supporting the 10 sleeve |58, this sleeve is secured to one end of a guide rod |6|. This rod is mounted for longi tudinal sliding movement in a.- tubular member |62 and this member is in turn mounted for longitudinal sliding movement' in bearings |63 16 formed in the disks 4|. It will be noted from Figure 11 of the drawings that the tube |62 ex tends parallel with and closely adjacent the tubu lar stem |36. As previously mentioned, the invention provides means for rotating the chuck and it is a feature of this invention that the chuck may be rotated at a speed which is independent of _the speed of rota tion of the drum on which the chuck is mounted. Referring now to Figures 1 and 2 of the drawings, it will be noted that there is provided a variable speed motor |10. By means of a chain |1| and suitable sprocket wheels this motor drives a shaft |12 which extends underneath the base 30 from one side ofthe machine to the other. Driven 30 from'the shaft |12 by means of a chain |13 and suitable sprocket wheels is a shaft |14 which car ries at its end a pinion |15 arranged to engagev teeth |16 formed on the outer periphery of a ring gear |11 which is journalled in the housing 33. It will be noted by reference to Figure 2 of the draw ings that the other end of shaft |12 drives through asimilar chain |13* and a shaft |14“ a pinion |15ß which is arranged to drive a ring gear To briefly outline the operation of the chucks, it will be apparent that as the drum's carrying the chucks are rotated, the chucks will be moved in a circular path about the shaft 35. During any desired portion of their travel the chuck jaws may be opened by retracting the head | 45, this being effected by suitably designing cam |60. When however, head |45 is not retracted' by cam |60, the head is resiliently urged forwardly by its spring |41 thus resiliently forcing the arms |4| 10 apart and moving the jaws to their clamping posi tion. . Additionally, at any time during the rotation of the drums, the chucks may be moved toward or away from each other depending entirely upon 15 the cam groove |83. Thus one or more constric tions may bc drawn in the glass tubes and addi tionally the shoulders adjacent the constrictions may be rounded, if -desired, by forcing the chucks slightly toward each other immediately after the 20 drawing operation. Thus the invention provides means whereby practically any desired pushing or pulling of the glass tube in the direction of its length may be effected during the travel of the glass tube in its circular path about the axis of 25 the rotating drums. ' The severing means It is contemplated by this invention that the glass tube processed will be cut into a plurality of 30 `lengths before it is discharged from the machine. While in the embodiment of the invention illus trated, means is provided for severing the glass tube only into two sections, it will be apparent that if desired, the tube might be divided into more than two sections upon the completion of the processing operations. To effect this severing operation, there is first in the housing 34, this ring gear being identical provided a revolving steel disk |95 which is ar 40 with the ring gear |11 but not being shown in the ranged to either score the glass tube or to cut en drawings. tirely through the same. As illustrated in Fig The ring gear is provided on its inner periphery . ures 2 and 17, this disk is preferably located ad with teeth |18 arranged to engage pinions |19 jacent the base of the machine so that the tubes secured to the stems |36 of the chucks. It will be are cut after they have made almost a complete 45 apparent that with the structure illustrated, the . travel around the shaft 35. ring gears |11 may be rotated at any speed inde pendent of the speed of rotation of the drums 36 and 31 and that since these ring gears rotatlvely drive the chucks,` the chucks may be rotatlvely 50 driven at any desired speed. This feature is of It is obvious how ever that the disk might be located at any desired 45 point to effect the severing action wherever de sired. _ l v The disk is counterbalanced to regulate the pressure at- which it engages the blanks and for importance for the reason’ that by properly rotat- f this purpose the shaft |96 which carries vthe disk ing the chucks and the tube blanks held thereby, is journalled adjacent the ends of arms |91 and the glass tubes may be evenly heated by the burn |918, these armsv being pivotally secured to the' ers which will be later described, and the heated upper ends of standards |99 carried by the base 30. Fixed to the arm |98 and projecting beyond 55 glass will distribute itself uniformly. Further, the speed of rotation may be controlled in de the standards |99 is an arm 200 which carries pendence upon the diameter and wall thickness a counterweight 20|.` This counterweight is of the tube blanks being processed. mounted in any desired manner for adjustment It also constitutes a feature of this invention to longitudinally of the arm 200 so that the pressure v60 provide means for reciprocating the chucks 60, with which the disk engages the glass blanks may 60 that is> for moving aligned chucks toward and be regulated. l away from each other. To accomplish this result The disk |95 is rotatably driven by the follow there is provided a yoke |60 which rotatlvely em- ' ing structure from a variable speed motor 205 braces a reduced portion of gear |19. This yoke shown in Figure 1 of the drawings. The motor 65 is carried by a sleeve |8| -which is secured to the - 205 drives a belt 206 which engages a pully 201 05 tubular member |62, this tubular member being rotatably mounted on the shaft 208 which forms mounted for reciprocation in the bearings |63, as the pivots for the arms |91 and |98. Fixed to the previously mentioned. Sleeve |8| carries a cam pulley 201 for rotation therewith is a second pulley roller |82 which is arranged to travel in a cam 2 |0 and this pulley is connected by a belt 2| | with groove |83 formed in an annular member |84 a, _pulley 2|2 fixed to the shaft |96. It will be 70 75 secured to the housing 36 as by the angle plates obvious that by mounting the pull'eys 201 and |85. It will be understood that the chucks car ried by drum 31 are also arranged to be recipro cated by a similar 'cam associated with the cylin 2|0 on the axis about which the arms |91 and drical housing 34. . , » l ' |98 rock, the disk may be conveniently driven despite the rocking movement thereof. If thel disk is arranged to only score the glass 76 5 2,125,027 tube blank or if for any reason, such as lnsuñl ' cient pressure, the parting of the blank is not ef fected by the rotating disk, this parting or sever ing of the blank is positively eiïected by the pro vision of a. member arranged to strike the glass blank at the scored part thereof. , The structure for accomplishing this is illus trated in Figures 15 and 16 as comprising an arm 220 pivotally mounted intermediate its ends as at i0 22! on a standard 222 supported on the base 30. Adjustably secured to one end of the arm as by ' the bolt and slot connection 223 and 224, is a 15 member 225 having an inclined end portion 226 arranged to engage cams 221 formed at spaced points on one of the rotating drums. As illus trated in Figure 2 of the drawings, these cams are preferably formed on the periphery of the rotating drum 36. . - A spring 230 secured to the other end of arm 20 220 tends to rock the arm about its pivot to cause the head 226 to engage the cams 221. Rocking ' movement of the arm is adjustably limited by a bolt 23! carried by a bracket 232 which is secured to the standard 222. , - Adjustably secured to the arm 220 and project 25 ing laterally therefrom is an arm 235 and adjust ably secured to the free end of this arm is a member 236 whichy constitutes the striker or ter 250. It will be noted that each ampoule has intermediate its ends a constriction 25| a‘înd that - further each ampoule terminates at one end in a. stem 252 of reduced diameter. As the drums 36 and 3l rotate, they _carry-with . them the chucks 55. As the chucks approach the feeding mechanism, the jaws of the chucks are opened by virtue of cams i60, while the chucks are retracted by virtue of cams ißt. Consider now that a. plurality of glass tubes H5 10 are placed in the hopper illu. VIt will be undei‘-, stood that the glass tube blanks are continuously fed one at a time from the magazine to the chucks carried by the rotating drums, but to sim plify the description, the progress of one tube 15 only will be described. This tube will be picked up by one pairl of the aligned notches in disks 85 and t6 and carried by the'rotation of these disks toa position where it will be picked up by one pair of lugs it. The 20 tube will be moved by the lugs along a path determined by the portions il@ of the guide rails i i3. Thus during a portion of. its travel the tube will follow the path of travel of the pair of chucks which are adapted to grip this tube. 25 As the tube comes into alignment with the pair of chucks, the chucks are moved inwardly by the rollers 182 engaging the cam groove E82 and the chuck jaws are permitted to close by virtue of v’ It will be noted by reference particu larly to Figure 16 that when the head 226 rides ` the fact that rollers i5@ ride off the cams i60. 30 30 This is illustrated in Figure 20 of the drawingsV off of one of the cams 221, the arm 220 is rocked bumper. to a position where the member 236 strikes the glass tube blank. To briefly review the operation of the severing mechanism, it will be understood that at a desired 35 point during the travel of the glass tube blanks, these blanks are engaged by the rotating sharp ened disk 995. This disk may either score the blanks or may be arranged to cut through the blanks depending entirely upon the pressure ex 40 erted by the disk on the blanks. After a blank has been subjected'to the action of the rotating disk, it is carried by the rotation of the chuck ' carrying drums to a position where it is struck by the member 236, this member being oscillated 45 by virtue of cams formed on one of the rotating drums, Obviously, the striking of the scored ‘ blank by the member 236 will sever' the blank at the scored portion so that the blank will be posi tively divided into sections. « Operation The operation of the machine is diagrammati cally illustrated in Figures 17 to 26 inclusive. Before however proceeding with a description of 55 the operation of the machine, it might be noted that while a glass tube blank is being moved through the circular path by _the rotation of the chuck carrying drums, it is subjected during pe riods of‘its travel to the heat of ñames issuing 60 from v4burners disposed between the rotating drums. These burners are in accordance _with the usual practice adjustably mounted with the result that while one particular method of oper ating the machine will be described in detail,\it 65 should be borne in mind that by properly adjust ing the burners and the cams which actuate the chucks, numerous shaping operations other wherein it will be noted that the chuck jaws are about to grip~ the ends of the blank to be processed. » With the ends of the tube gripped by the chucks, the tube is carried around and subjected intermediate its ends to llames issuing from an elongated arcuate shaped burner 255. ` The chucks will be rotated at a desired speed independent of the speed of rotation of the chuck 40 carrying drums by virtue of the ring gears l'l‘l with theA result that the intermediate portion of the tube being processed will be evenly heated and the heated glass will distribute itself uni formly about the longitudinal axis of the blank. 45 After the intermediate portion of the blank has _been heated sui’liciently, the chucks are moved away from eachother by the rollers i82 in cam grooves i83 to form a portion 256 of reduced di ameter in the tube. The portion of the rotation . of the drum during which this pulling of the stem occurs is diagrammatically illustrated in Figure l1 of the drawings. The next step is to form the constriction 25| in the ampoule and to accomplish this the glass tube blank adjacent one end thereof is subjected to the sharp flames issuing from suitably located burners 251. While the force of the dames issu ing from these burners may be and frequently is sufiicient to form a constriction of the desired 60 size, various lengths of constrictions and> various forms of shoulders adjacent these constrictions maybe suitably formed by moving the chucks toward and away from each other after the blank has been suitably heated by the flames from the 65 burners 251. _ ' ` yAs diagrammatically illustrated in Fig. 17, after u . than those described, may be effected by the the one end of the blank has been subjected to a constricting heat for a -suitable period, the 70 machine. For the purpose of illustration, the operation of> the machine incident to the production of am the constriction thushformed may be. subjected f poules will be described. Two of these ampoules « are shown in Fig. 26 of the drawings, each am 75 poule being designated by the reference charac chucks may be moved apart or pushed together 70 to properly shape the> constriction ,after ’ which to jets of cooling air issuing from nozzles 258 this being diagrammatically illustrated in Figure 23 of the drawings. Preferably, at the same time 75 6 2,125,017 the other end of the blank may be subjected to sharp 'flames issuing from burners 258, this heat ing being continued suiiicientiy long to either form the desired constriction» in the blank adja cent the other end thereof, or to heat this portion of the blank suiliciently to permit the forming of a desired constriction by properly moving the chucks toward or away from each other. ‘1111s second end of the blank is then cooled by suitable ,air jets from nozzles 260, the blank at this time being shaped as illustrated in Figure 24 of the and is not definitive oi' the limits of the inven tive‘idea. The right is reserved to make such changes in the details of construction and ar rangement of parts as will fall within the purview of the attached claims. What is claimed is: - 1.
