Specification of Letters Patent.

Application filed January 13, 1911. Serial No. 602,409.

To all whom it mag concern:

Be it known that we, J AMEs J osnrn GRIF- FIN, a citizen of. the. United States of "America, and GORDON Morrir'r PEACCCK, a-

subject of the King of Great Britain and Ireland, both at present residing at 1 Garden street, South Yarra, a suburb of the city of Melbourne,-in the State of Victoria, Commonwealth of Australia, machinist and draftsman, respectively, have invented a cer tain new and useful Machine for Tempo rarily Securing Metallic Container Ends Prior to Crimping or Double Seaming, of

which the following is-a specification.

This invention relates to the'afi'ixing of the ends to the bodies of canisters, tins and like containers such as those used for holding jam, preservesand divers similar sub I operations familiar to those acquainted with the art.

Hitherto the method followed has been to feed 'the canister bodies to a machine, loosely poise. a closing disk or end on each body and then double seam the'end to the body. This has often necessitated, as can be well understood,'the attendance of operators to feed the bodies and ends, and, in addition has rendered the double seaming machine complex in construction and operation. Further if either circumferention flange around the top'or bottom of the body were injured in any way a ,bad joint was necessarily made by the double seamer and if the conformation of the body were defective a perfect joint was impossible as the end could not then be concentrically arranged with the said body; Still further, in the treatment of preserves for example, where a body with the bot-tom end double seamed thereto is filled with fruit and the like and passed open topped through a steam exhaust chamber, although the material at the bottom of the container may be reduced to the'desired condition that at the top is often detrimentally influenced. It is common. here, it 'may be mentioned, to sometimesuse an end having a vent there in to prevent damage to the upper portion of the reserves in the container. A ain P e g where containers are filled with jams or preserves such as blackberry and raspberry,

which when heated rise abovethe top of the container, the top end, as at present applied, presses the jam or preserves down harshly and which at times has led to the loss of material. Still again, it is theoretically wrong to pass open topped containers holding any material whatever to the double seaming machine, exhaust box, or elsewhere as, if accidentally upset, the most, if notall, of the contents are wasted.

The object of this invention, while dispensing with atleast one quarter, is to remedy all the foregoing objections by pro Viding means for temporarily or partly securing an end permanently to a container body prior to and ready for crimpingbi double seaming, the latter being performed by a distinct and separate machine forming no part ofthe present invention. It may be mentioned, however, that great Sllllpllfiflb tion of the known crimping and double scaming machines 18 possible by the use of this invention. To fully comprehend the essence of the invention it must be borne in mind that container bodies are in the first place open at both top and bottom. 7 disk is then by this invention partly secured and maintained-in such a state during the operation. body isnow protected by the closing disk or end and is "fed to a double seaming machine. hen the ,end and body are to be double seamed the necessary material is placed in the container and the top, second, or final closing disk or end temporarily secured. Now this end being only partly secured it follows that in treating preserves, the top portion of the material cannot be affected, the end is sufliciently secured to -prevent that, but there is no necessity for a special vent as the unsecured portion of the end performs that function and acts as a 'vent;

in any circiimstanccthe bulk'of the contents A closing Patented Dec.17,1912.

to one end, the body being perfectly shaped The particular flange of the a is saved. So it will b seen that the generic" in'ventive idea underlying and embodied in the machine hereinafter described is to pnrtly'secure to a container body an end so that the same will be retained in position until and when the body is delivered to a complete crimping or double seaming machine for the full and permanent attachment of the said end to the said body whether the end and body pass through any intermediate stages or not.

Primarily this invention has been devised for treatment of that kind of container or receptacle hereinafter the description radiating arms 15.

called a can, consisting of an open ended body 2 around the top and bottom of which is an out-turned circumferential flange '3.

Thebody is closed by disks or ends 4 each.

having a central depression '5 and a circumferential flange 6. To convey the bodies 2 to, and also from, the machine about to be described, a continuously moving conveyor consisting of a feed and delivery belt 7 is provided. Upon this. the can bodies are placed ina vertical position. may communicate with a crimping or double seaming machine if desired.

This belt 7 l Situated at one side of the belt 7 is'a subsidiary framework 8. Driven by a sprocket wheel and chain, hereinafter-described, is a sprocket Wheel 9 secured upon a cross shaft' 10 mounted in suitable bearings in the said framework 8. Secured to the shaft 10 is a bevel wheel 11 engaging with a bevel wheel 12 secured to the lower end of a'vertical shaft 13. Secured to the upper end of the shaft 13 is a wheel 14 Adjacent to the framework andcentrally disposed above the. belt 7 is a closing disk or end reservoir consisting of four vertical guide rods 16. These may be supported in any well known way. Situated at each side of the belt is a; vertical spindle 17 also supported in any suitable manner andhaving secured thereon'a boss 18 from which radiate arms 19. Secured at the'top of each spindle 17 is a disk separating and retaining device 20. This is provided with a series of arms each alternate one of which has 'a flat upper surface but an undercut lower surface 21. The remaining arms, between those having undercut lower surfaces, each have a declining upper surface 22 but a flat lower surface. Each of the arms of the device 20 is thus precisely the opposite in conformation to that adjoining it.

having a series of Adjacent to the framework 8 and the closing disk -.or end reservoir is a main framework 23 havlng a feed end 2 1 and a delivery end 25. Ateach-side of the feed end are semi-circular guides fiifi. At-each side of the delivery end are semi-circular guides 27. Communicating with and extending between the lower ends of the semi-circularguides 26'a'nd 27 .at each side'of-the: framework is .a-lower guide '28. "Communicating with each ofythe semi-circular guides .26 is an upper converging guide 29. Communicat ing with each of the semi-circular guides 27 is an ,upper diverging guide30. Mounted slots 34. Projecting from each standard between it and the framework is a set screw 35. Mounted above each standard is. an

inwardly pressing pressure roller 36. Depending from the framework 23 above each inwardly pressing pressure roller is an alining or steadying roller 37. Mounted in suit-" able bearings at or near the delivery end 25 of the framework 23 is a transverse driving shaft'38. driven by a belt pulley 39. Secured upon the shaft 38is a toothed pinion 40. Engaging withthe pinion 40 is a spur wheel 41 secured ,upon a countershaf t 42.

Secured upon the said countershaft 42 be tween the guides 27 is a driving gear-43 provided around its circumference wit-h a series of pockets 44. Adjacent to each guide 26 is a bearing 45 .adjustable longitudinally upon the framework 23 by a set'screw 46. Supported by the bearings 45 is a transverse shaft 47 secured upon which, between the said guides 26, is a gear 48 provided with pockets 49 in its circumference. Secured upon the shaft 47 is also a sprocket wheel 50 driving by a suitable sprocket. chain 51 the sprocket wheel 9 aforementioned. Secured uponthe countershaft 42 is a-bevel wl1eel 52 engaging with a bevel wheel 53 ence.

secured upon a longitudinal shaft 54. Secured upon the longitudinal shaft 54 is a bevel Wheel 55 engaging with a bevel wheel 56 secured to the lower end of a vertical shaft 57. Secured to the upper end of the shaft 57 is a bevel wheel 58 engaging with a bevel wheel 59 secured upon a transverse shaft 60. Mounted upon-the shaft 60 and disposed above and bet-ween the aforesaid guides 29 and 30 is a depressing roller 61 provided with pockets, 62 in its circumferless link belt. Each link comprises a slide base 63 projecting from which are two can body guides 80. At each end of each slide base is a cross spindle 64 by which the links are united or pivoted together. At each end of each spindle is a roller 65. Slidable upon each slide base 63 are two slides 66 each provided with a guide roller 67. Formed in each slide are vertical guideways Upstanding above each slide, and having their bottom ends reposing in suitable sockets formed therein,

are a series of spiral springs 68. Within each slide is a can body clamping jaw 69 protruding outwardly from which is a' guide pin 70. Around each guide pin and interposed between the can clamping jaw and the slide is a spiral spring 71. Above each slide is a head piece or die 72 depending from which are dovetailed guides 73 engaging with the vertical guideways in the slides aforementioned. ln the'bottom of each die are sockets accommodating thetop ends of the aforesaid spiral springs 68. In the bottom of each die are horizontal slideways having undercut sides.

72 is a friction roller 74. Outstanding from With the foregoing is used an end- Mounted above die to contact with a roller 37 and move the die inward. Secured within each die 72 is a semi-circular ring 76 having around or'near its top a groove or recess 77. Slidable within the horizontal slideways aforementioned in the bottom of each of. the dies is a retaining block 78. Engaging with'each block 78 is'a flat spring 79 depending from a suitable recess or the like in the bottom of each die.

The cycle of operations is as follows The bodies 2 are-placed in a vertical position upon the feed belt 7 and conveyed to t-he'subsidiary framework 8 where they encounter the rotating radiating arms 15 of the wheel 14. By the arms 15 the bodies are timed or spaced correctly upon the belt 7'. The bodies so spaced then pass beneath the reservoir or guide rods 16 and in doing so come into contact with the arms 19 thereby rotating the spindles 17 and disk separating and retaining devices 20. As the devices 20 rotate an end 4 is first supported above and at each side of a body 2 by the fiat upper surface of one of the arms of each device. As the devices 20 continue to rotate the arms move from beneath the end 4 which consequently falls and then rests uponthe declining upper surface 22 of the next succeeding arm of each device. The wheels still continuing to rotate, the upper declining surfaces 22 move from beneath the end 4 which then falls upon the can body 2 passing beneath it. The next arm of each device, it will be clear, has a flat upper and an undercut'lower surface. It is thus obvious that, while the flat upper surfaces prevent the succeeding end 4 from falling, the disk or end which has already fallen is lower than the said upper surfaces and uninfluenced thereby and is passed over by the undercut surfaces 21. The pulley 39 is rotated by a belt or the like. By the pinion 40 and spur Wheel 41 the countershaft 42 is rotated turning the gear43, and also, by the bevel wheel 52 and gearing before described, the depressing roller 61. As the gear 43 rotates each of the pockets 44 in its periphery engages successively with the rollers 65 therebyrconveying movement to the link belt. Each of the .rollers 65 also .engages with the pockets 49 in the circumference of the gear 48 which latter is rotated by movement. of the belt. As each link moves upwardly around the gear'48 the slides 66 ,andhead pieces 72 carried thereby are separ ated and open so that the belt 7, may be passed. A slide 66 and die 72 thus obtains at eachvside of and above the belt 7 which however is itself centrally disposed above the slide base 63. The link belt and the belt 7 travel at the samerate of speed. As each link assumes a when passing around the gear '48, the guide:

vertical position,

p 5 of the end 4 to buckle,

rollers 67 of the slides 66 engage with the inner faces of the converging guides 29.'

As travel of the link belt continues it fol-- lows that the slides 66 are closed toward each other, the can clamping jaws 69 thereby eventually embracing a can body 2. A can body is centrally poised by the guide pins 70 and springs 71. As the links proceed further onward the rollers 7 4 each successively engage with the pockets 62 of the rotating depressing rollers 61. The effect 1 of the roller 61 is to force the dies 7 2 down ward, the guides 7 3 permitting of this movement. The spri ngs 68 are then compressed."

' 5 As the dies 72' move downward the blocks 78, which have already met at their inner sides, take up a position within the depression 5 in the relative can end l, the de pressing movement also flattening or pressing the flange 8' of thebody 2 at or nearly at right angles thereto. The end his firmly engaged with the cam body 2, the flanges 3and'6being in line with the grooves77.- The alining or steadyingrollers 37 and set 5 screws, 75 now .engage'and the rollers 67 come at"the same time into contact with the rollers 36 which force the slides 66 andfwith themithe dies 72 still farther inward; As' the blocks 78 have already met, the dies 72 3o slide-inwardly upon them against the tend ency'ot the springs 7 9 and 'asthecan clamping faws 69 have'already met and shaped the'body'toa perfect conformation the slides 66 compress the springs 71 and slide along the guide pins 70. The flange 6 of the end 4 projectingbeyo-nd the flange 3 of the body 2, the wall of the groove 77 comes into contact with the said flange 6 and bends it first downwardly and, asthe pressure continues,

1 inwardly beneath the flange 3. "lhis onl' occurs atfeach sideot'the body and en though, as will be apparent; and not circumferentially right aroundf the same. The blocks 78 as shown project slightly beyond the edges ofthe dies 72 whereby they meet and form a complete block to fill the depression -5 of the end 4 atthe moment the dies 72 are forced downwardly. The said depression is thus filledandany tendency when the final and innermost inward pressure; movement communicated to the slides 66 and dies .72 by the rollers 36, is prevented. The flange 6 willingly follows around the wall of the said groove 77,

I The travel of the link belt frees each of the rollers 74 from the pockets 62 of the .roller 61 successively, the dies 72 by the springs 68 remove the pressure from each can end 4 and lift the blocks 78 from the depression 5 thereof. The blocks 7 8 then assume, by action of the springs 79, their normal relationship with the dies 72. A similar action takes place between the slides" 66 we claim as new and desire to secure by Let- 65 and can clamping jaws 69 by the agency of the springs 71. The endbeing now firmly secured at each side of the body 2 and the depressing influence being removed, the slides 66 commence to be influenced, opened apart, orseparated by the diverging guides 7O 30 against the" outer faces of wlnclnthe .rollers67 bear.
