LEE C. SHARP, OF PLATTSMOUTH, NEBRASKA, ASSIGNOR TO FRANZ BR'U'CKMANN, JR., OF BRUNSWICK, GERMANY.

MEANS FOR CAPPING- AND PERFORMING OTHER OPERATIONS ON CANS.

Application filed March 8,

T 0 all whom it may concern:

Be it known that I, LEE C. SHARP, of the city of Plattsmouth, in the county of Cass and State of Nebraska, have invented certain new and useful Improvements in Means for Capping and Performing other Operations on Cans, of which the following is a full, clear, and exact specification, such as will enable others skilled in the art to which it appertains to make and use the same.

A special, though not the sole, object of my invention is to provide a machine by means of which the covers may be secured on cans when the cans are in upright position thus allowing the cans to be filled first with liquid or semi liquid contents and the cover applied hermetically without spilling the contents of the can.

My invention is especially adapted to fastening the covers by what is termeda roll seam which so firmly clamps together the cover and can body as to prevent the necessity of solder or other sealing substance in many cases.

My invention also involves novel mechanism by which the seams may be soldered, if it is so desired, and by means of which various other operations may be performed on the cans.

My invention further involves certain improvements in the devices for rolling the seam either inward or outward and for in suring a hermetic connection without subjecting the body of the can to undue strain.

My invention involves various other features of major or minor importance and all of them will be fully set forth hereinafter and particularly pointed out in the claims.

Reference is now had to the accompanying drawings which illustrate, as an example, one embodiment of my invention with certain modifications in the devices for forming the seam, in which drawings,

Figure 1 is a sectional elevation of the ma chine fitted with devices for rolling the seam inward; Fig. 2 is an elevational view with parts in section showing the machine fitted with devices for rolling the seam outward; Fig. 3 is a sectional plan showing the mech anism for rotating the table; Fig. 4 is an enlarged detail showing the act-ion of the crimping rollers on the seam and illustrat- Specification of Letters Patent.

ing the novel relation of said rollers to the seam sustaining ring or belt; Fig. 5 is an enlarged section showing the seam supporting ring and the position which the same bears to the seam before the clamping operation; and Fig. 6 is a detail of the devices shown in Fig. 2 for rolling the seam outward.

Referring first to Figs. 1, 3, 4, and 5, 10 indicates a boX casing forming the base of the machine from which rises a rigid hollow column 11. Surrounding the base of the column 11 and movable vertically thereon are two disks 12 and 14, the lower disk 14 rests on the top of the base 10 and is provided with one or more screws 15 by which the disk 12 is adjustably supported. These parts are non-rotatable and the upper disk 12 supports a flange 16 formed preferably integral with the table 17 and located under the same. The table has a hub 18 which is not only rotatable but longitudinally movable on the column. The engagement between the disks 16 and 12 allows the table to rotate, but imposes a certain frictional resistance to this rotation which prevents the table from moving by momentum and insures accurate operation of the parts. This table is provided, as shown best in Fig. 3, with shallow pockets 19 adapted to receive the cans which are indicated at a in the drawings.

In the base 10, the prime mover shaft 20 is revolubly mounted, the same being fitted with a band pulley 21 through which the shaft is rotated. The shaft 20 carries a cam- 22 and this is engaged by a roller 23 carried by an arm 24 dependent from the horizontal lift-er bar 25. Said bar has its ends extended through slots 26 formed in the base of the column 11 to enable the ends of the lifter bar to engage the under side of the disk 14 as shown in Figs. 1 and 2. Therefore, as the shaft 20 rotates an up and down movement is imparted to the lifter bar through the parts 22, 23 and 24 and the lifter bar causes the disks 12 and 14 and the table supported thereon to reciprocate vertically in a time controlled by the form of the cam 22 and speed of rotation of the shaft 20.

The shaft 20 projects through the base 10 and carries a miter gear 27 in mesh with a smaller gear 28 secured to a vertical shaft 29 carried revolubly in a bracket 30 projecting from the base 10. The upper end of the shaft 29 has fastened thereto a crank disk 31 on the pin 32 of which a. collar 33 is loosely mounted. To this collar 33 a link 34 is pivoted and this link is in turn pivoted to a collar 35 mounted loosely on a pin 36 secured to a slide 37. This slide is arranged to run freely in an annular pocket 38 formed in the table 17, and mounted on the slide is a spring pressed pawl 39 engaging a ratchet tooth 40 formed on the outer wall of the pocket 38. It will be seen, therefore, that upon rotation of the shaft 20 the table is given a regular up and down motion and also that, through the parts 27, 28, 29, 31, and 34, the table is given a regular step by step rotation. The pivotal connection of the link 34 with the swivel collars 33 and 35 allows this step by step rotation to be imparted to the table notwithstanding its vertical mot-ion and by properly proportioning the parts the movements imparted to the table may be rendered exact. and regular. The vertical movement of the table is intended to engage and disengage the cans with the devices for capping and otherwise operating thereon, and the rotary movementis intended to advance the cans from one step of the operation to the other.

The rigid column 11 carries intermediate its ends a spider 41 adapted to support the devices for crimping fluxing, soldering or for performing various other operations on the cans. According to the structure shown in Fig. 1 the spider has four arms, of which three designated 41 41 and 41 are shown in Fig. 1. According to the structure shown in Fig. 2 the spider has two arms designated 41 and 41. In Fig. 1 the arm 41 is illustrated as sustaining a device for forming a seam by clamping or rolling the flanges of the head and cover inward; the arm 41 is illustrated as sustaining a brush for supplying flux to the scam; the arm 41 is illustrated as sustaining a soldering device. In Fig. 2 the arms 41 and 41 are both illustrated as sustaining devices for forming the seam by rolling the flanges outward. I desire it distinctly understood that the invention is in no sense limited to the devices above referred to, and that it may be fitted with various tools and implements for performing various other operations on cans and similar articles.

Again referring to Fig. 1, 42 indicates a rotating spindle which carries a band wheel 43 over which a belt 44 runs to impart to the spindle continuous rotary motion. This belt passes around idler pulleys 45 carried on an arm 46 of a spider 46 secured to the top of the column 11. The spider 46 as here shown has four arms of which three are visible in the Fig. 1, 46 46 and 46. The upper part of the spindle 42 is carried in the arm 46 and the lower part of the spindle projects downward through a box in the arm 41" of the spindle 41. At its lower eX- tremity said spindle carries a crimping head 47 provided with crimping rollers 48 acting on the flanges of the can body and head and serving to roll inward the seam as will be fully set forth hereinafter. A frusto-conical cam 49 is secured to the spindle 42 above the spider 41 and thiscam is adapted to act on rollers 50 mounted on the upper ends of four levers 51 pivoted at equidistant points from each other on pins 52 carried by the arm 41 of the spider 41. These levers 51 respectively carry at their lower ends quadrants 53 which match to form a box-like inclosure for the crimping head 47. Said quadrants 53 carry respectively the four quadrants of a ring 54 which is adapted to embrace the can during the crimping operation and which is provided with an anvil ring 55 adapted to lie under the seam during the crimping operation. This ring 55 is also in four quadrant shaped sections respectively carried by the quadrants 54. The arm 46 of the spider 46 has mounted there on a lever 56 which has a connection 57 with the spindle 42 by means of which vertical reciprocation may be imparted to the spindle. The inner end of the lever 56 is connected to a rod 58 which extends down through the hollow column and is provided with two rollers 59 engaging opposite sides of the cam 60 fastened to a shaft 20. It will be seen, therefore, that the spindle 42, notwithstanding its continuous rotation, is by the devices 56, 58 and 60, given a regular up and down motion bringing the crimping rolls 48 into engagement with the seam, and also by the action of the cam 49, throwing inward the lower ends of the levers 51 and causing the quadrants 53 and 54 to close around the crimper head and the upper part of the can, with the result that the anvil ring is pressed snugly under the seam to back and sustain the same during the crimping operation, preventing the can from collapsing under the pressure of the crimping rollers. The instant that the spindle 42 rises and the cam 49 disengages the roller 50, the quadrants 53 and 54 disengage the can and allow it to drop with the table out of engagement with the crimping devices. If necessary suitable springs may be applied to assist this disengaging action of the quadrants.

Referring particularly to Figs. 4 and 5, which show enlarged details of the crimping devices it will be seen that the spindle 42 carries the crimping head 47 through the medium of a loose pin 61 allowing the head 47 to have a limited gyrating movement on the spindle. 62 on the spindle and the head 47 is a rubber pad 63 which sustains the head firmly, but at the same time allows it to yield to adapt Interposed between a collar 1 55 close around the can by the operation before described, they assume, as shown in Fig. 5, a position directly under the outwardly disposed part of the flange a the anvil ring snugly engaging the sides of the can body adjacent to this flange. It will be seen that this ring, therefore, forms a rigid support for the seam of the can during the crimping operation and by referring to Fig. 4, it may be seen that the crimping rollers 48 operating to turn or roll the flanges a and b inward to form the seam, exert their pressure directly against the anvil ring enabling the seam to be formed under great pressure insuring a hermetic joint and avoiding subjecting the body of the can to any collapsing strain. The important principle of this feature of my invention is the outward flanging of the can body producing a shoulder under which the anvil ring 55 may lie so that the roll seam may be formed directly opposite the anvil ring and hence subjected to that pressure which is necessary to form the seam eifectually without, however, destroying or straining the can body.

In Fig. 2 the spindle 42 does not rotate but is merely vertically movable by the mechanism before described for this purpose. The crimping rollers 64 in Fig. 2 are arranged to roll the seam outward and downward for which purpose the can and cover are provided with outward or horizontal flanges. Said crimping rollers 64 rotat-e around their own axes and are carried to move bodily around the axis of the shaft or spindle 42 by means of levers 65. These levers have slide ways 66 formed at their lower ends and the rollers 64 are mounted on slides 67 which are adjustable in the slideways and held by means of set screws passing through the side walls of the slide ways and engaging the slides. The levers 65 are fulcrumed within a pulley 68, the hub 69 whereof is rotatable around the spindle or shaft 42 and bears on the crimping head 70 which is secured to the lower end of the spindle. As the spindle descends to engage the head in the cavity in the top of the can, the levers 65 actuated by the cam 71 on the spindle are moved so that their under ends carry the crimping rollers into engagement with the flanges of the can body and head. A belt is arranged to drive the pulley 68, and as the crimping rollers move around the can they form the roll seam.

Fig. 2 shows two crimping devices one at one side and one at the other side of T'the column 11, these devices being duplicates of each other. Fig. 6 shows the details concerned with the formation of the outwardly crimped seam. The crimping head 70 of the spindle 42 is formed with a peripheral groove 72 and the crimping rollers 64 have at their upper ends flanges 73 which fit in the groove 72. Since the crimping operation involves a thrust on the crimping roller in the direction of the arrow indicated in Fig. 6, this engagement of the flange 73 in the groove 72 causes the thrust to be com municated to the head 70 and the center pin of the roller is thereby saved from strain. Further by forming this engagement between the crimping roller and head the flange of the can top is prevented from being swaged inward and the formation of a wire edge at this point is prevented. Heretofore in the formation of seams of this sort the flange has been crowded in at the inside of the seam and a sharp edge left which not only is dangerous in the handling of the can but which also prevents the formation of a tight seam. The body a of the can is as shown in Fig. 2, formed first with an outward flange a and the cover or top 5 of the can is formed with an upwardly extending flange b the cover being depressed into the body as shown in Fig. 2. The crimping head when it engages the cover is received in the cavity in the top thereof and the crimping roller acts against the flanges and rolls the same down into a seam as indicated in Fig. 6.

In Fig. 1, 74 may be taken to indicate for example, a brush for applying the flux to the seam of the can and 75 a soldering iron heated by a gas burner 76. The brush 74 is carried by a spindle 77 and the iron 75 by a spindle 78 which is preferably hollow to conduct the gas to the burner 76. The spindles 77 and 78 are mounted in boxes on the spider arms 41*, 46 and 41 and 46 respectively and they are rotated by means of chain gearing 79 and 80, from the spindle 42, the chain gearing 79 having sufficient slack therein to allow the above described vertical movement of the spindle. As before indicated the specific nature and function of the devices 74 and 75 are in no sense essential to my invention; the machine may be adapted to perform various other operations on the can or other article operated on.

In the operation of the machine as a whole, assuming for example, that it was used to cap, flux and solder full cans, upon the rotation of the shaft 20 the table 17 is given a regular step by step rotary move ment combined with a vertical movement. The operator has nothing to do but to place the full cans with the covers resting loosely thereon in the pockets 19 in the table as these pockets are successively presented. As the can passes to the crimping device, the table raises the can into the space inclosed by the quadrants 53 and 54. At this time the spindle 4L2 descends engaging the crimping rollers with the flanges of the can body and head and simultaneously closing the anvil ring around the can body under the flange a thereof (see Fig. 5). The crimper head rotating the rollers 48 around the flanges rolls the flanges in, forming a roll seam as illustrated in Fig. 4, the anvil ring 55 backing the operation of the crimping rollers as before explained. The anvil ring then. opens and the crimper head ascends simultaneously with the dropping of the table, disengaging the can from the crimping device. The table is then given another forward step and the can previously crimped is brought under the fluxing brush 74:. Flux may be supplied to this brush in any desired manner for example through a longitudinal passage in the shaft 77. The table then rises engaging the can with the fluxing brush after which the table descends, is given another forward step, and the can is brought under and then raised into engagement with the soldering devices 75 from which the can passes, if desired, to a fourth operation performed by mechanism supported-like the devices 74 and 7 5 on a spindle carried at the back of the machine. It will be seen that with this machine the plurality of operations are carried on simultaneously. These operations may be any number desired according to the equipment and adjustment of the machine. The operator has nothing to do but to place the cans on the table and remove the finished cans therefrom. The special utility of the invention adapted as a can capping machine is that it allows the operation to be carried on While the can is full of a liquid or semiliquid substance. If it is desired to solder the seam thus formed, the soldering operation is also performed with the can in upright position and without danger of spill ing its contents.

As shown in Fig. l the covers or caps of the can may be provided with annular gutters immediately adjacent to and alongside of the seams for the reception of solder. The form of seam illustrated in Figs. 1, 4 and 5 is particularly adapted to be soldered, while the form of the seam illustrated in Figs. 2 and 6 depends upon the crimping for a tight oint. In some classes of work the crimped seam is sufliciently hermetic while in other classes of work, such for instance as the packing of foods for export the addition of solder is desirable.

While I have herein shown and described the invention as especially adapted to automatic operations on sheet metal cans, it is apparent that it could be used in the manufacture of various other articles and is in no way limited to the specific work here shown.
