CAN-CRMPING MACHINE.

SPECIFICATION forming part of Letters Patent No. 476,558, dated June 7', 1892.

Application filed January 29, 1892.

T @ZZ whom it 71u03/ concern:

Be it known that I, JOHN IV. ROBERTS, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain nenT and useful Improvements in Can-Crim ping Machines, of which the following, with the accompanying drawings, is a specification.

My invention relates to machines for crimpio ing the ends upon the cylindrical part of tin packing-cans.

The object of my invention is a machine embodying a rotary can-carrier, mechanism which automatically grips the cans and cri m ps I5 the ends upon the body part of the cans, and

also rotary tables in conjunction with the rotary can-carrier.

My invention consists in the construction and combination of parts described herein and dened in the claims.

In the accompanying drawings, Which form a part of this specification, Figure 1 is a side elevation of my machine. Fig. 2 is an enlarged side elevation of the same, the rotary can-carrier and tables being broken away. Fig. 3 is a section of Fig. 2 on the line Vy y. Fig. 4 is an enlarged side elevation of the crimping-disk reciprocators, and Fig. 5 is a plan of the same, partly in section. Fig. G is a cross-section of Eig. 5 on the line c 5c. Fig. 7 is a section on the line of Fig. 2. Fig. S is an enlarged broken section of the circular rotary carrier-frame with friction-band. Fig. 9 is an enlarged edge view of my beadingdisk. Fig. 10 is an enlarged edge View of the crimping-disk. Fig. 11 illustrates the parts of a can prepared for crimping. Fig. 12 shows the parts of a can put together ready to be crimped by my machine, and Fig. 13 is a view ofthe completed can afterbeingoperated upon. Fig. 14 illustrates the separate parts of a can prepared for beading one end of the can to give it the appearance of being Wired. Fig. 15 is a View of the parts put together to be operated upon for beading, and Fig. 16 illustrates the beaded can after being' operated upon. Fig. 17 is a reduced central vertical section of Eig. 14. Fig. 1S is a central vertical section of Fig. 15, and Fig. 19 is a central vertical section of the vertical plunger.

For the sake of clearness I first describe the Serial No. 419,720. (No model.)

rotary can-carrier and the tables that operate in conjunction therewith.

A vertical shaft 1 stands in a journal-block 2 and is supported laterally by the frame 3. 55 A carrier-frame 4 is fixed upogi the vertical shaft 1 above the frame 3, the hub 4' of the carrier-frame 4 resting and turning` upon the horizontal arm 3 of the frame 3. Around the circumference of the rotary carrier-frame 6o 4 is a seriesof journal-boxes 5,through which pass the spindles 6, carrying the can-carrier disks 7. Around this rotary can-carrier is a friction-face, which is preferably formed vby a band S, Whichbears against a yielding block 8 to avoid vibration of the carrier. The block S may be of rubber faced with wood or metal, or it may be a Wood or metal block with springs back of it. Above the rotary carrierframe 4 is a circular table 9, thatis fixed to the 7o vertical shaft l, and above the circular table 9 is a like table 9', fixed upon the shaft 1, and above the table 9 is a similar circular table 10, xed upon the vertical shaft-1and having a hopper 11 supported therefrom by means of .7 5 straps 11. The table 9 is designed to carry loose tops of cans. The table 9' is intended to carry loose bottoms of cans, and the tableI 10 and the hopper 11 are intended to carry the cylindrical or body parts of cans.

Upon the vertical shaft 1, beloyv the horizontal arm 3 of the frame 3, is fixed a drivegear O, and below the gear O there is shown a friction-Wheel12, Which bears against the friction-block 12. The block l2' is similar 85 in construction to the block S', hereinbefore described.

The friction-Wheel l2 and the friction-band 8 may be dispensed with, or the friction-Wheel 12 may be fixed at a different place upon the 9o shaft 1; but I prefer to use the friction-band 8, as illustrated.

In will now describe the gripping and crimping mechanism of my machine. The fraude supporting this mechanism consists of a vertical standard 13, having lateral arms 14, 15,

16, and 17, which carry the vertical shaft 181 that turns in the journals 14`15, 1G', and 17. To the lower end of the vertical shaft 18 is fixed a bevel-gear 19 and to the top of said loo shaft 1S is fixed a bevel-gear 20. Collars 18 are fixed upon the vertical shaft 18 to prevent chine.

vertical movement of said shaft, one of said collars being above the journal another below the journal 16, and another above the journal 17. To the opposite side of the standard 13 are lateral 'arms 21, 22, and 23 for supporting other operative mechanism of the marlhe lateral arm 21 is strengthened and supported by the upright 24, and a crosstie 25, extending from the standard 13 to the upright 24, gives greater rigidity to the frame, and the vertical tie 23" stiffens and makes more rigid the lateral arms 22Y and 23.V The main horizontal shaft 26 passes through openings in the standard 13 and upright 24 and has its inner end supported by the bracket 27 and its outer end supported by the bracket 28. Said horizontal shaft 26 turns in the jou rnals 27 and 2S. Upon the outer end of the shaft 26 is fixed a drive-pulley 29, and a mutilated bevel-gear 30 is fixed to the inner end of said shaft 26. Said mutilated bevel-gear 30 meshes with the drive-gear 0, that is fixed to the vertical shaft 1 of the rotary can-carrier. the standard 13, is fixed a bevel-gear 31, which meshes with the bevelggear 19. An upright 32, supported from the top of 'the standard 13, and an upright 33, supported from the top of the lateral arm 23, carries the -horizontal shaft 34. The horizontal shaft 34 turns in the journals 32 and 33. Upon the outer end of the horizontal shaft 34 is xe'd a bevelgear 35, which meshes with the bevel-gear 20. A vertical shaft 36 is carried in the journals 22 and 23 at the outer ends of the lateral arms 22 and 23. A collar 36 above the journal 22' and a like collar below the journal 23 prevent vertical movement of the shaft 36. Said shaft is supported above the orbit of the can-carrying disks 7. To the top of the vertical shaft 36 is fixed a bevelgear 37, to mesh with the bevel-gear 33, that is fixed upon the end of the horizontal shaft 34. An elongated boss 37 of the gear 37 extends down to the journal 23. The shaft 36 has vertical adjustment in the collars 36 and the bevel-gear 37 for the purpose hereinafter described. This adjustment through the collars 36 is secured by means of the set-screws 36n and through a key upon the inside of the gear 37 and boss 37', which fits loosely with the slot 36, formed in the vertical shaft 36. Vhile the shaft 36 is adjustable vertically, the gear 37 remains in one position, that it may always mesh with the gear 38. To the lower end of the shaft 3o is fixed a disk 36". Upon the lateral arm 21 is fixed a block 39, having gibbcd sliding-ways, in which the slide-block 40 reciprocates, and upon the lateral arm 22 vis fixed a block 41, having gibbed sliding-ways, in which the sliding block 43 re ciprocates. A vertical shaft 42, having its lower end in the journal 40, passes up through the slot 22 in the lateral arm 22, through the slot 41 of the slide-block 41, and through the journal 43. The only difference between the blocks 39 and 41 is that block 41 is slotted, as

Upon the horizontal shaft 26, outside Varms 21 and 22, are alike, and therefore adescription of the upper one only is given, it being illustrated by Figs. 4, 5, and 6, and the same reference-figures are placed to like parts ofY each reciprocator.

The slide- blocks 40 and 43 have a borre 44 therein, into which entersV the rod 45. A spring 46 is placed in the bore 44 back of the rod 45. The opposite end of the rod 45 is threaded,.as seen at 45. The bar 47 has a bore in its front end, into which enters the threaded end of the rod 45. The entrance of the rod 45 into the bar 47 is shown Vby the dotted lines on the bar 47 in Figs. 4 and 5. Said bar 47 has a lateral opening 47 through it, into which is placed a worm-wheel 49. The worm-wheel 49 is bored axially and threaded to screw upon the threaded portion of thc rod 45. A worm-gear 50, turned by the handwheel 51, operates the worm-wheel 49. It will be seen that byY turning' the hand-wheel 51 the worm gearand wheel will lengthen or shorten the reciprocating apparatus, as desired. The bars 47 reciprocate in openings through the standard 13.

Instead of making the wheel 49 a wormwheel, it may be made a plain wheel bored axially and threaded to screw upon the rod 45, and other means than the worm-gear employed t-o turn it. Various means for turning this wheel will readily suggest themselves to mechanics. I prefer, however, to use the worm-gear, as a finer adjustment can be se cured therewith than by other means.

ln the back end of the bar 47 is pivoted a friction-roller 4S. Upon the vertical shaft 13 are fixed cams 52 to engage the friction-rollers 4S. As the pressure of the cams 52 is brought against the friction-rollers 4S by the rotation of the shaft 18, the reciprocators are thrust forward, carrying the vertical shaft 42, and as the pressure of the cams 52 is released the retraction-springs 53 will withdraw the reciprocators to their extreme back-stroke.

Upon the vertical shaft 42 are fixed the crimping-disks 54 and 55. The disk 55 has vertical adjustment upon the shaft 42 by means of a set-screw 55. Said disks are beveled, the lower one 54 to its under side and the upper one 55 to its upper side.

A bracket 56, carrying a journal 56', is attached to the front side of the upright support 24. A rectangular plunger57 works vertically in the box-journal 56. The top 57 of the vertical plunger is a cap fitted upon the plunger-bar 57 and is cupped out on top to receive the lower ends of the spindles 6.

IOO

IIO

A rubber block 57" is interposed between the plunger-cap 57 and the top of the plungerbar 57 to allow a slight yielding of the disks 7 and to cushion the bearing of the plunger against the spindles 6. A friction-roller 5S is pivoted to the lower end of the vertical plunger 57. Upon the lower horizontal shaft 26 is fixed a cam 59 to engage the friction-roller 5S. The vertical plunger is below the orbitl of the spindles 6, with their disks 7. XVhen the carrier-frame t stops after each intermittent rotary movement, the Vertical shaft 36, one of the spindles C, and the plunger 57 are in a vertical line.

A throw-off 63, supported in the front of the machine by the bracket G-l and having vertical adjustment therein by means of the setscrew G5, operates to discharge cans from the machine after being operated upon as they are carried on and come into contact With thc horizontal bent end G3 of the throw-off.

ln the operation of my machine the parts of cans represented by GO, 61, and G2, Fig. 11, are first prepared and the cylindrical parts 60 are placed in the hopper 11 and on the table 10. The bottoms 62 are placed upon the table 9 and the tops are placed upon the table 0. The vertical shaft 42 and the disk 55 are adjusted vertically to the length of the cans to be operated upon, and the length of the reciprocators is adjusted to the diameter of the cans, as hereinbefore described. The operator takesthe prepared parts of acau and puts them together, as illustrated by Fig. 12, and then sets the can top end down upon one of the can-carrying disks 7. The position of the cans upon the disks 7 is shown at A, Figs. 1 and 2. The mutilated gear 30 rotates the shaft 1 and can-carrying apparatus intermittingly and brings the disks 7 successively under the disk 36". As each disk 7 comes under the disk 36 the cam 59 on the horizonvtal shaft 2G comes in contact with the frictionlower ends of the spindles Gare rounded thatl they may turn easily on the cupped plungerhead 57. The can A is raised high enough to bring the edges of the ends G1 and (52 op posite the edges of the crimping-disks 5i and 55. As the can A is gripped and While being revolved, as described, the cams 52 on the vertical shaft 1S come into contact With the friction-rollers 48 on the reciprocators and force the reciprocators in, thus bringing the edges of the disks 51 and 55 against the turned edges of the can ends G1 and G2. The turning of the can A causes the disks 51 and 55 to revolve. The can A makes several revolutions While the disks 5i and 55 are in operation against it. As the grip of the can is released by the turning of the cam 59, the cams 52 release their pressure and the springs 53 Withdraw the reciprocators, and the mutilated pinion 30 rotates the can-carrier far enough to bring the next succeeding disk 7 under the disk 36', when the operation described is repeated. As the cans are carried around after being operated upon they come into contact with the horizontal arm 63 of the throw-oit G3 and are caused to fall int-o a chute or receptacle placed by the side of the machine to receive them.

The purpose of the springs 46 in the slideblocks 40 and 43 back of the rods 45 is to provide a yielding bearing for said rods 45 anda yielding to the disks 5% and 55 to overcome any unevenness in the surface of cans operated upon and also to cushion the stroke of said disks against the cans. I

Sometimes it is desirable to bead cans around the lower edge to give them the appearance of being Wired. This is mostly done with the larger sizes of cans. To bead a can around one end to give it the appearance of being Wired the cylindrical part 65, Figs. 14 and 17, is curled over upon its edge, as seen at G5. The end G7 of the can is formed as illustrated in said iigures. The parts are then put together by the operator, as illustrated by Fig. 15, and placed top down upon the carrier-disks 7, as already described for ordinary crimping. Instead of the beveled disk 55, I employ a disk having a rounded groove 68 around its periphery, as illustrated by Fig. 9. This Will crimp the end over the turned edge G5 of the can-body G5and bead it, giving it the appearance of being Wired, as illustrated by Fig. 16.

The adjustment and operation of the machine for beading cans is the same as for crimping cans, as hereinbefore described.

It will be seen that my machine is very simple in construction and operation, and that the can-carrying apparatus intermittingly rotaies to bring cans into position to be gripped, and that the gripping and crimping are accomplished automatically.

My machine may be used either with or Without the tables, orany one ortwo of them, for carrying the loose parts of cans to be operated upon; but Iprefer, as a matter of convenience to the person ending the cans, to use the tables.

4If the machine be built to crimp but onesized cans, the means for giving vertical adjustment to the vertical shaft i2 may be dispensed with and the means for adjusting the length of the crimpingdisk reciprocators need not be employed; but as the capacity of the machine is so great it is advisable to use these adjusting devices, so that one machine may be made to operate upon cans of various sizes.

My invention may take on various modifi- IDO not., therefore, limit myself to the form and arrangement of parts as shown and described.
