(Cl. 419-7) 1 , . . 2 - . This is an invention for a machine for sealing poules in position for sealing, the facility with ampoules> or equivalent containers of fusible ma terial such as glass after `the same have been filled. Due to the fact that ampoules of the same ca which they may be emplaced in and removed from the machine, the means for compensating for the variation in the> size of the ampoules which maybe sealed by the machine and the pacity vary considerably in the outside diameter manner in which the parts of the machine sub ofthe necks thereof, it is essential in sealing the same by the direct action of a flame jet impinged thereagainst that the length of time to which the neck is subjected to the heat of the flame jet be regulated to within precise and very narrow limits to avoid damage to the ampoule and waste of the contents. When the fusing and sealing are 'carried out by and depend upon the judg ment of an operator, only those of experience and 15 possessing a high degree of skillfcan perform this type of work satisfactorily. ‘ The present invention comprehends a machine of the character set forth and for the purpose specified which functions to automatically fuse jected to the heat of the flame jets are cooled to protect the same against damage by overheat ing. 1 ' With the above enumera-ted and other objects in View, the invention is set forth in greater de tail in the following specification, particularly pointed out in the appended claims and illus trated in the accompanying drawings, in which: Fig. 1 is a front view of an ampoule sealing machine constructed in accordance with the in vention with portions broken away to show the underlyingstructure with the ampoules clamped in place and illustrating the position of parts irn 20 mediately prior to the starting of the machine. and seal one or a plurality of ampoules simul taneously and which machine is so ,constructed and arranged and so actuated as to apply the ' Fig. 2 is a plan view thereof with portions bro ken away. ~ ` ' » " Fig. 3 is a vertical sectional view through the machine taken approximately on the line 3_3 of 'heat' -t'o the neck of each individual ampoule for» precisely the length of time required to obtain 25 Fig. 1, illustrating the flame jets inactive and showing the gage heads and their arms set at the proper fusing and .sealing thereof in accord relatively different positions with reference to the ance with the diameter of the neck of each am rack bars for varying the time of application of poule, thereby practically eliminating damage the llame jets. l -thereto or waste of the contents by faulty sealing.

The invention also resides in a novell means for effecting the application of the ñarne jets to the ampoules and the discontinuance of the same 40 thereto, together with means governed by the size of the outside diameter of the neck of each in .dividualampoule for controlling the time of ap plication 'of said jets in order to insure proper fusing and sealing thereby avoiding considerableV waste.

The cam disk 81 is formed with a spiroidal periphery 9i` which merges into a tangential edge 92 and is so gen erated as to gradually increase in >distance from its axis of rotation> in the direction in which it turns from its juncture with the inner end of the rack bar 69. The gage heads 68 are respectively tangential edge 92 to its juncture with the outer mounted for swing` movement on horizontal axes end thereof.

By virtue of this ar by guide rods‘96 extending upwardly from .the rangement it willv be apparent that the weight base I6 and supported at their-upperendsby of the rearwardlyprojecting arms 61 functions angle elements 91 secured to and projecting rear-' vto lnormally swing the lower ends of the gage heads forwardly. ,It therefore follows that when 30 wardly from the upper ends V.of the bearing brackets 56 and , 51. Attached to the opposite the spring fingers 21 engaging the ampoule necks ends Aof the angle bar 95 and alsoguided for verti contact with the lower ends of the gage heads <cal- movement are a pair of upstanding arms 98 each of which has journaled thereon a cam-roller sizes of the outside vdiameters of the ampoule 35 99 which cam rollers are respectively engaged by the cams 81 and 93, so that upon each complete necks. Thiswill in> turn set the rear terminals rotation of the cam shaft 88 the cams 81 and'93 ‘69 of the arms/61 at varying heights alongside willeffect the raising and lowering of the angle of the teeth 10 of therack .bars 6D, it being ap bar 95. The sector shaped cam 85 and the cam parent that the ampoule necks of larger outside disks 81 and 93 are so related or positioned with diameters will dispose the spring fingers 21 far reference to each other that as they turn in a ther forward than those of smaller outside diam counter clockwise direction as viewed in Fig. 3 eters, hence the rear terminals 69 of the arms 68, said gage heads will be selectively, swung rear wardly varying distances commensurate with the 61 corresponding to >the smaller ampoule necks will be set at a higher level than‘the rear ter the trailing edge of the cam 85 passes beyond . the cam roller 86 just as the low point of the cam disk peripheries of the cams 81 and 93 start to engage the `cam rollers 99. This insures the minals" of the arms o-f the larger size ampoule necks. It will also be appreciated that due to lateral shifting of the frame 15 and the engage the'A leverage arm proportions thus defined the ment of the rear terminals 69 of the arms 61 with relatively longer length of the arms 68 with ref the teeth 10 of the rack bars 60 immediately prior erence to the length of the lower ends of the gage head will greatly magnify the relative/dif 50 to the raising of the angle bar 95. As the angle bar 95 moves upwardly it will contact the termi ferences between the outside diameters of the nals 69 of theA arms 51, it being apparent that ampoule necks as evidenced by the variations in the terminals which are disposed lowermost will the vertical settingsof therarm terminals 69. be raised first to cut off the air pressure jets and l In order to shift the rear terminals of the arms 61 laterally into engagement with the'rack teeth 55 permit the flame jets to be impinged against‘the ampoule necks which obviously are those of larger 10 of the rack bars 60, after said terminals have outside diameter. As the anglev bar 95 continues been set in accordance with theneck sizes of the to ascend it will engage with the other arm ampoules, Va frame 15 is provided which is terminals successively, it being apparent that mounted for lateral shifting movement in guides those which are disposed highest will be engaged 16 attached to the upstanding brackets 56 and 51 last and hence the flame jets permitted torim and said frame has secured thereto a plurality of vertically disposed transversely spaced angle bars 11 between which the arms 61 respectively pinge against the ampoule necks of smaller out- ' side diameter subsequent to those of larger diam eter. When the cam disks 81 and 93 have com extend so that lateral movement of the frame will effect corresponding movement of the rear por 65 pleted a rotation the tangential edge 92 register ing with the cam rollers 99 will permit the angle tions of the arms coincident therewith to engage bar 95 to descend rapidly thereby lowering the the rear terminals 69 thereof with the rack bar angle bar 95 to its initial lower position. At this teeth 10 when the frame is shifted to the right, as stage of the operation, the beveled leading edge viewed in Fig. 2.

It will be evident from the con struction and mode of operation set forth `that the length of time which the 'flame jets are ap plied to the individual ampoules in accordance with the size of their outside diameters, is con trolled by starting the application of the flame jets to the ampoules at varying times and discon tinuing the application of said flame jets simul taneously.
