Application May 13, 1935, Serial No. 21,176 11 Claims. My invention relates to a machine for cleans ing receptacles and the covers thereof, and more especially milk cans and covers for said cans. One of the objects of the invention is to pro 5'1 vide improved mechanism for reversing the cans from an inverted position to an upright position entirely by mechanical means, and maintaining a proper relation between a can and its cover, so that the cover can be applied to the can at the 104 delivery end of the machine. Another object of the invention is to provide mechanism for moving the cans from station to station so that the cans are properly located at 15 5 the successive stations. The invention will be best understood by ref erence to the accompanying drawings, forming a part of this speci?cation. Figs. 1 and 1a are side elevations of a single line straight line washer, showing the general de 20.v sign of the machine and how some of the more important members are assembled. Fig. 2 is a side elevation showing the means for producing the compounding movement for indexing the can into the inverter, the length of 25» this last compounding movement being greater than the distance between the stations of the machine which are anterior the inverter. 30'. Fig. Fig. Fig. Fig. Fig. 3 is a plan view of Fig. 2. 4 is a side elevation of the can inverter. 5 is an end elevation of the can inverter. 6 is a plan view of the can inverter. 7 is a side elevation of the can inverter and of the gear train which produces the different movements of the indexing mechanism and which 35; also produces the intermittent rotation of the can inverter. This ?gure also shows the means for applying the power of the gear train and (C1. 214-1) crank pin I29 mounted in a boss thereof. T-bars 95 have depending arms 82, which are connected to a cross-pin 19 which passes through a bearing of pitman 18, so that pitman 18 can turn relative to cross pin 19. Hence a single pitman 18 moves the T-bars 95 back and forth in. unison. This pitman 18 is connected to crank pin I29. In moving the can from position K (see Fig. 2), into the can inverter, as designated by position D, the can has a greater distance of travel B than in its previous intermittent movements from station to station. The length of each said previous movement is designated by A. This longer ?nal feeding movement is secured by com pounding the movement of the last pair of in 15 dexing ?ngers 9| (see Fig. 3), this being desirable so that the inverter bars I04 (see Fig. 2), will not contact with the milk can while it is in position K and while the inverter is being turned. This compounding movement is accomplished 20' as follows: 4 Can indexing ?ngers 9! (see Figs. 2 and 3) are pivoted by pins M2 to slidable bars 93. Said slidable bars 93 are slidably mounted in slide bearings Ill, said bearings Hi being mounted on the T-bars 95. ' Pitman members 89 are pivotally connected to the respective slidable bars 93 at 99, and each said pitman 89 is pivoted to a lever 83 at B5. Said levers 83 are pivoted to a frame member F at 84. The levers 83 are caused to rock forward and backward by links 8T, which are pivotally con nected to the respective depending arms 82 of T bars 95 at 88, and each link 87 is pivotally con nected to a lever 83 at 86. The slide bars 93 are thus actuated in unison. As shown in Figs. 1 and 2 the cans are fed into the machine at the left hand end of Fig. 1. Since each depending arm 82 is rigidly connect caused to rock backward if the normal operation 4.01‘ of the machine is obstructed, in order to dis-. ed to and has the same movement as its T-bar 40' 95, it is clear that each lever 83 at its pivot point connect the motor power from the gear train. 86, will- have practically the same stroke as the Fig. 8 is an end elevation of Fig. '7. Fig. 9 is an end elevation showing the means respective depending arm 82. However, pivot for mounting the motor 50 as to enable it to rock point 85 will have a longer stroke than point 86, how the motor is mounted so that said motor is 45" backwards. The machine has a main frame to which the other parts are connected.v Said main frame comprises steel channel-irons F. ' ‘ The mechanism for indexing or feeding the 50‘; cans in successive intermittent strokes, from sta tion to station of the machine, and ?nally into the inverter, is generally shown. As shown in Fig. 1a, the reciprocating move ment of the can indexing-mechanism is pro 55' duced by the rotation of gear 8|, having the since 35 is at a greater distance than 86 from pivot 84, and consequently this longer stroke will be transmitted to the slide bars 93 and the supple mental indexing fingers 9| which are mounted on said slide bars 93. The slide bars 93 have the full stroke of the 501' T-bars g5, plus the extra stroke of pitman 89 over pitman 81. The outer ends of ?ngers 9| carry pins I [4. At about the end of the'forward stroke of the ?ngers 9|, pins H4 will contact with the heads 2 2,129,137 of adjustable bolts 92’, which are connected to the frame of the machine, so that the ?ngers 9I will assume an inoperative position. Near the end of the backward stroke of indexing ?ngers 9i, the pins I I4 (see Fig. 3) will contact with the heads of adjustable bolts 92 which are connected to the frame of the machine, thus causing the ?ngers III to rotate on their pivot pins H2, and the ?ngers will then be turned into the oper 10 ative position illustrated in Fig. 3. While the 15 cans are being moved by the indexing mecha the teeth of the gear III, the shoe I20 restrains the gear I I1 against further movement, until the bars 94, which are connected to the frame of the machine. teeth I2Ia again mesh with the teeth of gear I H. The can is indexed into the inverter by the for— ward movement of the can indexing mechanism, and during the return stroke of the can indexing tive diameters, depending upon the speed with 15 which the machine is driven. For example, in revolution, thus inverting the can and depositing same on stationary can trackbars H5 (see Fig. 2). The tops of bars I I5 are lower than the tops of bars 94, but substantially flush with the in verter bars I04, so the can, when inverted to po sition E, will rest on can track bars H5 and in 25 verter bars I04. Can ejector members I31 are connected to and they move in unison with slide bars 93, so that upon the next forward move ment of bars 93, the members I3'I will engage the The gears I22 and H9 can have different rela Fig. 1a the gear I22 is represented as having a larger diameter than in Fig. '7. Referring to Fig. '7, the gear I22 turns in the clockwise direction, and the gear I I9 turns in the 20 counter-clockwise direction. The gear II'I meshes with the idler gear H6, and said gear IIE meshes with the gear IIO, which is keyed to the shaft III‘! of the inverter. and cover indexing mechanism as well as the The gears H6 and III) are of the same diam 25 eter, and the gear II'I has one half the diameter of the gear IIO‘ so that there is a gear ratio of 1 to 2 between the gear II‘! and the gear I ID. The shaft I01 of the inverter is mounted in bearings I09 as shown in Fig. 8. 30 The can inverter is shown in detail in Fig. 1 and Figs. 5-8 inclusive. Frame I05 and abutment member 20 are fas tened to shaft I01. As shown in Fig. 5, the frame I05 has a rectangular shape, having side bars 35 and end bars. To frame I05 are welded spacers I06 to which are welded four bars I04, as shown in Fig. 5. Bars I04 are rigidly fastened together by bars I08. The can inverter is assembled in the ma 40, chine so that its bars I04 are located between the can track bars 94 and H5. When the inverter is turning of the can inverter in a single direction. This improved can inverter is the ?rst which bottom pair of bars I04 are ?ush with the tops inverted can and move it out of the outlet side 30 of the inverter, at the same time that a can is being indexed into the inlet side of the inverter by ?ngers 9I. Said can ejector members I37 are located above the bottom bars I04 of the inverter. The ejector members I31 are connected to rods ~ I30, which are connected to bars 93, and the rods I38 slide in bearings I39. The intermittent turning of the can inverter is produced by a pair of intermittent gears forming part of the gear train shown in Figs. 7 40 and 8, this train of gears producing the recipro cating movement of the can indexing mechanism 45 operates wholly by positive mechanism, thus elim inating the use of the force of gravity, thus pro viding a positive and accurate method of invert ing a can which is of great value, as it is impera tive that the inverting of the cans be accom 50 plished in a de?nite and precise manner, in or— der to prevent cans from becoming jammed in the machine. Likewise, it is the ?rst inverter which is turned in a single direction, instead of being rocked. The train of gears (Figs. 7 and 8) functions as follows: suitable gearing. Spur gear I22 continuously turns a large spur gear II 9 which is keyed to shaft I26. in the position shown in Fig. 2, the tops of the of track bars II5, whose tops are lower than the 45 tops of track bars 94. This arrangement permits the can to enter the inverter on track bars 94 and to leave the in verter on track bars H5. The members I31 pro vide sufficient indexing movement for the ejected can, in order to provide clearance for bars I94 when the inverter is turned. The can indexing mechanism is positively op erated at all times and it is superior to the pawls which are now commonly used. The can indexing ?ngers II engage the necks Drive motor I23 turns spur gear I22 by any 60 The peripheries of the shoes H8 and I20 are shaped to permit the gear I IT to make a com plete revolution, while the gear I2I makes a half revolution. The shoes H8 and I20 then reach the respective positions which are shown in Fig. 7, so that as the teeth I2Ia go out of mesh with 1O nism into the inverter, they slide on stationary mechanism, the inverter will make one half of a 55 When gear I2I makes one complete revolution, gear III will make one complete revolution, but gear II'I makes its complete revolution while gear IZI is turning 180°. ' Keyed to shaft I29 is a driving intermittent or mutilated gear I2 I, having teeth I 2 Ia on one half its circumference only, the other half being pro vided with a shoe I20. The periphery of said 65 shoe I20 is circular and concentric with shaft I26, save that the ends of said shoe I20 are rounded. Said shoe I20 has a periphery of T80° The radius of the periphery of shoe I20 exceeds the pitch radius of gear teeth I2Ia of gear I 2|. 70 Driven gear III has teeth over its complete cir 55 of the cans, so there is no reciprocating mecha nism beneath the cans. When a can is introduced into the machine, it is placed in inverted position 'upon the plate I64. 60 In said position the can is pushed into the ma chine by means of dog IIS'I, which is pivoted at I68 to an extension of T-bars 95. When a cover Ca is introduced into the machine it is located upon the upper track bars I8, in the position 65 shown at the left-hand side of Fig. 1. The dog I15, pivoted at IT? to a vertical bar I465, moves the cover into the machine, from its initial posi tion. The ?rst indexing of a can and cover is pro cumference and the same number of teeth as gear duced by dogs I61 and I15, but after said ?rst I2I. Said gears III and I2I mesh. Gear II‘! has shoe II8 connected thereto, and said shoe has a concave periphery, which corresponds to the con 75 vex periphery of shoe I20. movement, the cans are indexed from station to 70 station by indexing ?ngers, as previously ex plained, while the covers are indexed by cover feeding dogs I 0. 1 75 3 2,129,137 Cover feeding dogs II) are pivoted at I84 to re ciprocating longitudinal cover-feeding dog-bar I46. Stops I44 limit the lowest positions of dogs In and stops I4‘I limit their uppermost positions. The stops I44 and I4’! are transverse bars, con nected to the longitudinal bar I46, which is con nected to bar I4Ba. Bar MM is connected to bar I46, by vertical bars I461). During the forward movement of bar I 46 the 10 dogs Ill pivotally attached thereto will engage the covers and index them at one station. The hold ing dogs 9 ‘which are pivoted at I43 to a station ary frame member, fall behind the covers and prevent their being moved backward upon the re 15 turn stroke of bars I46 and I tea. When bars I45 and M?a are moved rearwardly, dogs 9 hold the covers against rearward movement, and dogs Ill then rise, slip over the covers, and then fall be~ hind the covers for the next feeding stroke. The covers are discharged into a chute I5I 20 down which each cover slides by gravity to the uprighted can on which the cover is retained in a tilted position. Referring to Fig. l, a crank 83’ having a pin 86 25 is keyed to shaft I26. This is also shown in Fig. 8. Said pin 80 is connected to link 30!], which is pivoted at 300a. to bell-crank lever 3M, pivoted at 302 to the frame of the machine. Bell-crank lever 3UI is pivotally connected at 302a. to link 30 3433 which is pivotally connected at 304 to a de pending arm of cover-indexing bar I46a. Re ferring to Fig. 1, the pins 81! and I29 are non aligned, so that when a can and cover are intro duced into the machine, said can and cover are 35 not indexed in unison. The can and cover may each have the same number of intermittent feed ing movements through the machine, but the re spective feeding strokes are not in unison, and they do not have the same distance of travel. 40 That is, at every movement of a can, it is moved the same distance, save for the compounded movement into the inverter, and possibly the ?rst movement produced by dog I61. Every move ment of the cover has the same distance of travel, save when the cover enters the chute I5I. .I-Iow - ever the movement of a cover will be greater than the movement of a can, since the stations for the cover are spaced a greater distance than the sta tions for the can. The stations for the cover are 50 therefore not superposed relative to the stations for the can. In the ?rst position of the can within the ma chine, the milk residue is allowed to drain out of the can. In the next two positions, the can is pre-rinsed, said pre-rinsing being carried on in two stages. In the ?rst pre-rinsing stage I can use ordi nary cold water from a city line or the like. In the second pre-rinsing stage I can use cold water or warm water which may be supplied from the city lines and which may be led through any suit able heater. The next operation is the ?rst washing stage which is performed by means of water having any suitable cleansing material in solution. The wash water is supplied to the nozzles W under suitable pressure, from the tank T, by means of the pump 47. The next operation is the “sterile rinse,” using 70 sterile rinse water from any suitable source. The can is then subjected to a series of steam ing operations, three steaming stations being il lustrated.‘ The steam for said operations is drawn directly from a suitable boiler 75. shown) . (not The. can is now dried, two drying stations being shown in this machine. The can is now indexed into the inverter, and it is then inverted. Fig. 1 shows the pipe line I00 which supplies Wash water to the head II, which washed the cov ers. Fig. 1 also shows a steam ejector ‘Hi2 which draws water out of a suitable tank and forces the same through the nozzles ‘I63 and ‘FM for sterile 10 rinsing of the cover. The nozzle 'IMa supplies the sterile rinse water for rinsing the inside of the can. Fig. 1 also shows the washing heads ‘565 for rinsing the outside of the can with sterile water. 15' .Fig. 1 also shows washing heads ‘I'M for sup plying wash water to the outside of the can. A safety device is provided for disengaging the gear I22 from the gear I19 and thus stopping the entire drive of the machine if a can becomes 20' jammed or if the operation of the machine re— quires more than normal power. Referring to Figs. 7 and 9, the motor IE3 is mounted upon a platform 880 and said platform 89!] is provided with depending lugs which are 25. connected to a shaft 8IlIa, said shaft 86m. being mounted in suitable bearings BIO which are con nected to the frame of the machine. The plat form 800 also has depending lugs 805’ which can abut the frame F, as shown in Fig. 7. The plat 30. form 800 is also provided at its rear end with up standing lugs 8000. to which a lever 805 is pivoted at 805a. Said lever 885 is also pivotally con nected at 301 to a lug 806 which is rigidly con nected to the frame of the machine. The lever 351 895 is pivotally connected to an upwardly extend~ ing link 80m whose length may be adjusted by a turn-buckle device or the like. The upper end of the link 8M has a hook Said whichlever-.802 passes through is pivoted the at opening 803 to inthe a lever frame of 40 the machine and said lever 802 is provided with an adjustable counterweight 884. As previously stated, the gear I!!! turns in the counterclockwise direction. Hence the reaction 45 of the gear I22 tends to turn the platform 800 in the counterclockwise direction around the shaft Bill. This tends to lower the rear end of the platform and to lower lugs 800a, so that lever 8% is turned downwardly on pivot 801, thus pulling down link 80m. The counterweight 804 is adjusted so as to supply the necessary driving force for the machine. If this driving force ex ceeds the desired limit at any time, the reaction on the gear I22 causes the platform 899 to turn counterclockwise. The bell crank 8I2 which is connected to limit switch L, which is normally held by spring La in the circuit-closing posi tion shown in Fig. '7, is actuated by rod film, the lower end of which is connected to platform 80!). 60 The platform then trips the limit switch L, thus opening the circuit of the electric motor I23. The lugs 805’ limit the turning of the platform in the clockwise direction. The latch 8i Ia which is pivoted at BI I, may also be provided for hold ing the platform 78%, in the position in which the switch remains tripped. The latch BI Ia as shown in Fig. '7 is in its inoperative position, but when the platform 8% is rocked counterclock Wise, the latch BI id will turn by gravity so that 703 its shoulder will engage platform 80D and hold same until the latch is manually released. I have shown preferred embodiments of the invention, but numerous changes and omissions could be made without departing from its spirit. v 4 2,129,137 In particular, when I use identi?cation numerals in the claims, this is merely for convenience and the claims are not to be limited to the speci?c embodiments disclosed as a part identi?ed by a numeral is to be considered as representative of general means for accomplishing the particular function involved.
