ADJUSTABLE SQUARE-,CAN-HEADING MACHINE.

SPECKFICATIGN forming part of Letters Patent No. 692,912, dated February 1 1, 1902.

Application filed June 21, 1901.

To all whom, it may concern.-

Be it known that we, WILLIAM RUBIN, residing at South Omaha,and LEE OoATs SHARP, residing at Omaha, in the county of Douglas and State of Nebraska, citizens of the United States, have inventedrcertain new and use.

ful Improvements in Adjustable Square-Oan- Y Heading Machines; and we do hereby declare the following to be a full, clear, and exact delo scription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates lto can-heading machines for heading square or irregular-shaped cans.

The objects of the invention are, first, to provide a simple device for crimping or double-seamin g the heads on square or irregularshaped cans; second, to provide an independ- 2 o ent adjustment for each part of the machine; third, to provide elastic carriers for the can bodies, heads, and bottoms which will admit of the cans being rotated on their longitudinal axes during the crimping or seaming process z 5 without being removed from the carriers.

In the accompanying drawings, Figure 1 represents a view -in side elevation of a machine embodying our invention, portions being broken away to more fully show the parts.

Like numerals indicate the same partswherever theyoccur in the various figures of the drawings.

The machine is supported upon a suitable base l, upon which are adj ustably secured two bearing-heads 2, in which are journaled two 5o shafts 21.

other and are provided upon their opposite Said shafts are in line with eachinner ends with can-holders 20. The shafts are given an intermittent reciprocating m0- tion by the rocker-arms 6, which are pivoted at 5 between lugs 44, depending from the bot- 55 tom of th'e bearing-heads 2, and are provided with rollers 9, which run in grooves of cams 7, secured upon the shaft 8, journaled in bearings upon the frame 1, the upper ends of the rocker-arms being forked to embrace cross 6o heads or collars 3, loosely secured on said shafts 2l between fixed collars 3, as clearly shown in Fig. 1, so as to permit of the free rotation of the shafts in the cross-heads. The shaft 8 is driven by power applied to the pul- 65 ley 10, which is provided with an ordinary clutch device 46`and 47, operated by a lever Secured to the shaft 8 are two large segmental gear-wheels 1l, which during a portion of their revolution engage with the pin- 7o ions 4 and rotate the shafts 21 the required number of times for crimping and seaming a can. Y

Secured to the shafts 21 are disks l2, having in their peripheries notches 51, Fig. 3. Rollers 13, journaled in links 49, pivoted to standards 4S, projecting from the frame, are held against their disks l2 by the tension of springs 14, connecting'the links and arms. At the end of the engagement of the toothed portions 8o of the gears 11 with the pinions 4 the rollers 13 drop into the notches 51 and hold the shafts 21 stationary until the toothed segments of the gears 11 again mesh with the pinions 4, when, the shafts are again rotated, the rollers 13 85 riding out of the notches. Springs 15, coiled upon shafts 2l outside of heads 2, serve to normally and yieldingly press and hold disks 12 in position against pinions 4, the latter being rigidly secured on the shafts.

Shaft 33 carries the can-feeding device, which comprises a plurality of carriers arranged radially about a common center, as is shown in Fig. 2. Said carriers consist of jaws 19,which are pivoted at 59 between the plates 95 36 36, which form peripheral flanges on hub 37, and are normally held together by the tension of the springs 35, attached to pins 53 on the jaw 19.' Between the jaws and extending radially from the central blockor'hub 37 roo are arms 34, which serve to hold the jaws 19 19 in a definite radial position. In Fig. 4 is shown in dotted lines the position of the jaws during the crimping or seaming operat ion and Y while the can is being rotated.

Curved plates 52 are secured to the jaws 19, and the plate of each jaw laps over the plate of the jaw of the next cancarrier, so that the spaces between the carriers are always closed and all danger of cans from the feedchute 42 passing between adjacent carriers is thereby avoided.

In the operation of the machine can bodies, heads, and bottoms are fed into the chute 42, whence they drop between the jaws of the carriers. The hub and carriers are rotated intermittently by a ratchet-disk 16 on shaft 33, which is operated by the spring-pressed pawl 50 on lever 45, the connecting-link 17, and the crank 18 on the shaft 8. As the cans, bodies, heads, and bottoms come between the can-holders 2O on the inner ends of the shafts 21, the spring-pawl 38, held to head 2 by pins 61 6l, passing through slot 62, drops into one of the notches on a disk 39 on the shaft 33, and the feed mechanism is held stationary during the crimping or seaming operatiom As thecans come into position the holders 20 are pushed inward by rock-levers 6, as before described, and hold the can,which at the same time is rotated by the gears 11 and pinions 4, as described. The crimping or seaming rollers are at the same time brought into position and the heads and bottoms are crimped or double seamed upon the can-body. The revo-r lution of the square can is permitted by the yielding opening and closing of the jaws 19 of the can-carriers, as before described. As the rotation of the can-feeding mechanism is continued the finished cans are removed from the carriers by the ejector 41 and drop into chute 40, from whence they are received in anysuitable receptacle. The spring-actuated levers 25 and double loosely-pivoted rollers 22 are especially adapted to following the ou tline of and crimping or seaming square or other irregular-shaped cans.

All the parts of the machine are independently adjustable and are so strongly and economically constructed that wear or liability to breakage is reduced to a minimum.

At 22 are indicated two pairs of crimping and seaming rollers, each pairl pivoted between the opposite ends of parallel bars 63, mounted loosely on pivot-pins 54, secured in lugs 53, projecting from' blocks 23, these blocks carrying shanks extending downwardly therefrom and engaging sockets formed in the upper ends or heads 24 of the levers 25, secured in position by set-screws 56 in the said upper ends or heads 24. The levers 25 have hubs 28 at their lower ends provided with tru nnions 29, journaled in lugs 30, projecting from the frame 1. In a bracket 26, bolted to the frame l, are sockets 27, in which are seated springs 65, bearing against the bottom of cu ps 43, secured or formed upon the levers 25, said springs being regulated as to their tension by set-screws 64, projecting through the walls of the socket 27, the said springs forcing the levers 25 toward the shaft 8, their distance therefrom being regulated by means of press-rollers 32, which are pivoted to levers 25 and bear against cams 3l, secured to shaft 8. There are two sets of double crimping-rollers 22, one for the head and one for the bottom of the cans, each set being independently and yieldingly pressed against the cans while they are being revolved during the crimping and seaming operation.

At 40 is indicated a discharge-chute secured below the can-carriers, and 41 indicates an ejector rigidly secured, so that the notches 66 in the jaws 19 or" the can-carriers will pass over it, and thus insure the removal of the can already seamed or crimped from between the jaws and its dropping into thedischargechute.

Having now described our invention, what opposite inner ends of said shafts, a second,

shaft, acan-carrier hub mounted thereon, and can-carriers projecting laterally from said hub, each carrier consisting of two jaws and a spring for normally holding them together, the hub being so located that the carriers will be brought into position between the canholders and the cans will be rotated thereby, substantially as described.

2. The combination with a suitable framework and bearings mounted thereon, of canholders and means for positively actuating them to alternately clamp the can endwise and release the same, a shaft, a head or hub mounted thereon, radially-located can-carriers projecting from said hub, each can-carrier consisting of two can-inclosing jaws pivoted to the head, a spring connecting the said jaws for normally drawing the jaws together upon a can, and telescoping flanges on the adjacent jaws of adjacent pairs for closing the space between the latter, substantially as described.

3. The combination with a can-carrier and means for holding and rotating a can in acarrier, of a lever pivoted tothe frame, a head on the lever, lugs upon said head, an arm loosely pivoted at its center between said lugs, crimping-rollers pivoted in the opposite ends of said arm, means for yieldingly pressing the lever toward the can in the carrier, and means for pressing the lever away from the can, substantially as described.

4. In a can heading and crimpingmachine, a can-feeding mechanism comprising a central hub 0r disk, can-holders thereon, each consisting of a pair of jaws yieldingly pressed IOO IIO

wardly therefrom, the curved plates on the jaws of one carrier overlapping so as to telescope with the plates on the jaws of the adjacent carriers, substantially as described.

5. A can-feeding mechanism for a crimping or seaming machine comprising a hub or disk, circular plates forming peripheral iianges on each side of said hub or disk, radial arms projecting from the hub, can-hold ers projecting from the hub, each side of the j aw pivoted between peripheral flanges on opposite sides of the arms, and springs passing through the arms and secured at their ends to the jaws, substantially as described.

6. The combination in a can heading and crimping machine, of two shafts in line with each other, can-holders carried on the inner opposite ends thereof, a main shaft, a suitable driving-Wheel on the main shaft having gear-teeth on a portion of its periphery and the rest of its periphery plain, a pinion on each can-holder shaft adapted to engage the teeth of the gear-wheel, a disk on each canholder shaft having a notch in one side, and a roller normally pressed against the periphery of the disk and adapted to engage in the notch thereof, while the smooth portion of the periphery of the driving gear-wheel is passing the teeth of the pinion, substantially as described.
