CAN-BODWFLANGING MACHINE.-

Patented oct. 6, 1908.

Application filed. December 4, 1906. Serial No.` 346,282.

To all whom it `may concern." e f y Be it known that we, VICTOR ODQUIsTand I-IALvon HEYERDAHL LYoIIE,-both'citizens of the United States, and both residents of Chicago, in the county of Cook and State of Illi nois, have invented va certain new, useful,

and Improved Can-Body-,Flanging Machine, of which the following isa full, clear, and exact description, such as will `enable others skilled inthe art to Whichit appertains to make and use the same.

Our invention relates to canA making maw chines, and has particular reference t0 machines for Hanging can non-circular bodies preparatory to seaming the ends or heads thereon. 1

In order to seam the heads upon can bodies both `the heads andthe bodies must be fianged, previous to the process of scanning; and the function of the machine is to form the necessary ange upon the can body.

The object of our invention is to provide asimple, compact, andvdurable machine for Hanging can bodies, and one which will rapidly' and eiiicientlyflange both ends of a can body simultaneously.

Another object of our invention is to provide a machine of the class mentioned which shall be capable of Hanging can bodies of any shape or size. i

A. further object of our invention is to provide` a machine of this class, which will,

operate with great exactness to form'flanges of equal or` predetermined width upon can bodies; and one which when set inoperation will automatically complete the flangingof the can body and then stop preparatory to the removal of the can body and the insertion of another.

`Other objects of our inventionA will appear parts, all as will be hereinafter fully described Vand particularly set forth in the claims.

-Ourinvention willbe more readily understood by reference` to the accompanying drawings, `and in which- Figure I is aside elevation of a machine embodying our invention, parts being broken away'for the sake of greater olearness; Fig. II is a bottom plan View on an enlarged scale of the fianging roller carrying mechanism, the operating cam being omitted to better illustrate the remaining parts; Fig. III is a vertical section on the line III-III of .Fig II; Fig. IV is a similar view on the line IV-IV of Fig. II; Fig. Vis a cross section of the roller carrying slide on the line V-V of Fig. IV; Fig. VI is a bottom plan view similar to Fig. II, on a slightly decreased scale, showing the roller operating cam in place; Fig` VII is a detail plan view of a `portion of the operating mechanism; Fig. VIII is a plan view of a can body holding chuck such as is used in flanging oval can bodies; Fig. IX is an elevation of the chuck illustrated in Fig. VIII looking in the direction of the arrow a; Fig. X is a section {onthe line X-X of Fig. VIII, illustrating the chuck in its lowermost position, and a can body in position to be iianged, the same being shown in dotted lines; Fig. XI is a view similar to Fig. X, illustrating the chuck inits raised position; and F ig. XII is a detail illustrating the coaction of the roller and chuck in Hanging a can body.

In `order that our invention may be more readily understood, a brief description of the machine will be given as a whole, before describing the same in detail; it being` understood that no attempt will be made therein toparticularize, the idea being merely to present the machine as a unit, to the end `that its modus operandi may be grasped at once.

The operating mechanisms, including means for starting` and stopping the Inachine, are mounted upon a suitable frame and suitable brackets attached thereto. A l Hanging roller is rotatably supported from a Ibracket overhanging the frame, and means are provided for giving'the same several orbital revolutions, after having been started,an`d`automatically operative means for `stopping said roller when it has made the `required revolutions. A non-circular canbody holding' chuck is located beneath the tlanging roller and suitable means are provided for imparting` verticalV reciprocation thereto at the proper times. rllhis comprises a foot actuated lever and suitable connections therebetween. The same lever is also used to start the machine, by throwing in a clutch ;-connecting the constantly rotating drive shaft with the operating mechanisms.

A can body is first placed in the chuck, with its edges somewhat above and below the upper and lower edges of the body portion of the chuck. Then the operator raises the chuck and can-body by means of the foot lever. By this operation the flanging roller is placed within the can-body and the clutch is thrown in to start the machine. Suitable mechanism then automatically throws the roller outwardly and rotates it orbitally against the can body and the Aflanges provided thereon at both top and bottom bend the edges of the can body over the edges of the chuck, forming the required flange. The roller is kept in operative relation with the chuck and can body until it makes one or more complete circuits thereof, after which' 1t is automatically retracted, and the machine stopped.

1 indicates the frame of the machine, and 2, 3, 4, and 4', brackets which support the operating mechanisms thereon. The main drive shaft 5 extends from bearings in the bracket 2 to bearings in the bracket 4, and is provided with a fast and a loose pulley, G and 7. A belt shifter S extends to the forward part of the machine, where it is within easy reach of the operator. A sleeve 9, equipped with a worm 10, is loosely mounted upon the drive shaft 5, and is coupled therewith by a clutch device 11. The clutch 11 is operated by a foot lever 12, and in the following manner. A lever 13, carrying a pin 14, is connected to the lever 12 by a rod 15. As the foot lever 12 is depressed, the lever 13 is also depressed, and the pin 14, carried thereby, engages the end of a lever 16, pivoted in the bracket 3, and operates the same to throw the clutch 11. A latch 17 engages the pin 14, and keeps the clutch in operation until the machine has operated to flange a can body, when it is automatically tripped to stop the machine, as will be described later.

A worm wheel 2O is mounted upon the bracket 4', and engages the worm 10. Attached to the worm wheel 2() and concentrically mounted therewith on the bracket 4', is a cam 21, which operates a lever 22, to throw the Hanging roller into and out of operation, in a manner described hereinafter. Upon the bottom of the cam 21 is a lug 24, which, when the machine is at a standstill, depresses a lever 25 upon the end of a shaft 2G. This is the shaft to which the latch 17 is attached, and consequently, when the lug` 24 engages the lever 25 the latch is held out of engagement with the pin 14, and the lever 1? is permitted to rise. `When thc machine is started the foot is kept on the lever 12 nntil the lug 24 passes beyond the lever 25, allowing the latch to engage the pin 111-. Then the foot may be removed and the machine will continue its operation until the cam '1 has made one revolution. when the lug :21 again trips the latch as described. A spring- 27 returns the levers 12 and 13 to normal position, and in doing so. thc end of ther rod 13 operates the lever 1G to shift the clutch 11. thereby stopping the machine. The end ot the lever 13 actuates a brake shoe 2S, which. by engaging the loose portion of the clutch, insures the stopping of the machine at the proper time. This is withdrawn from operative position when the level' 121 is depressed to start the machine.

The chuck comprises a non-circular clamp in which the irregularly shaped can body is held during the process of tanging. a plate upon which the clamp is supported, a gage for positioning the can bodies in the clamp. and a latch for keeping the clamp closed.

The clamp consists of a stationary portion $0, fastened securely to a. plate 231. and a portion 32, hinged as at 33 to the part 11). rlhe parts 30, 32, are so shaped as to tit snugly. when closed, about the. can body and grip it when closed thereon. separate chuck is provided for each .size and shape of can to be flanged upon the machine. Thr` hinged part has a handle 341-, to facilitate opening and closing the chuck clamp, and a latch 2&5. serves to hold the clamp tightly closed while the machine is in operation. The plate 31 is recessed as at 3G, and the clamp members are so arranged as to slightly overhang the edges thereof, as .shown in `Figs. X and Xl. This is to permit the lower edge of the can body to be bent thereunder. See Fig. X11. The chuck is supported upon a vertically reciprocative shaft, 3S, mounted in a bracket 39, adjustably secured to the front of the fran'le 1. The shaft 38, and the chuck, are operated by the lever 12. A chain or other flexible member 40 is attached to an adjustable collar 3S upon the shaft 21 and passes over a roller 41, mounted upon the bracket 39, or if desired upon the frame 1. The flexible member 40 is attached to the lever 12 through a turn-buckle 42 and spring 4?. The collar3S limits the upward movement of the chuck by abutting the end of the guide or sleeve of the bracket S39. lllhen 2ans of greater or less height are flanged, it is evident that the bracket 39 must be lowered or raised. The turn-buckle -12 atl'ords ample adjustment for the lifting device` and the spring 43 a lost motion to permit further depression of the lever 12 after the up .stroke of the chuck has been arrested by the collar 3S.

The can body before flanging is of greater height than the clamp of the chuck, and the excess extends equally above and below said lamp. Thisis the portion which is bent flanges, and as the Hanges must be of certain Iand uniform size, the can, bodies must be placed in the clamp with great exactness. l ,This would present nov difficulty if the botl lk'.'tom of the recess 36 could be utilized to gage the position of the can body in the clamp. But this is impracticable as the space between the bottom edge of the clamp and the bottom of the Vrecess would not be sufficient to accommodate the Hangeof the Hanging roller. Hence a gage must be provided to insure accuracy and a uniformity in the flanges formed. To this end the chuck is provided with a false bottom and means for raising and depressing the same at the proper times. 45indicates the false bottom. This comprises a plate coextensive in area with the recess 36 and contained therein. Two rods or posts 46 are attached to the bottom thereof and extend through the bottom of therecess 36. When the chuck is down, ready to insert a can body.,V the rods 46 rest upon adjusting 'screws 48 in the bracket 39, which elevates the plate 45. ,The exact position ofthe plate at this time. can be determined by the screws 48. Then the chuck is raised, the plate dropsV to the bottom of the recess, giving ample room forfthe Hanging roller. y The clamp` holds the can body securely enoughto prevent the lsame from dropping with the plate 45.

The Hanging roller consists of a cylinder 50, provided with an annular flange or rib 51 at each end. `The distance between the ribs 51 is slightly greater than the height of the clampingmembers 30-32, so that as the roller is pressed outwardly against the can body and the clamp, the edges of the` can body are turned outwardly to form the flanges, as shown in FigVXH, in which 53 indicates thecan body.

against rotation, and the Hanging roller revolves about the inner face thereof. Fur! ther, the roller is `automatically thrown into and out of engagement with said can body at the propertimes, and further, means are provided for maintaining the roller in contact with the can, throughout the Hanging operation, whatever the shape of the can may be. To these ends the roller is mounted upon a suitable lever, which is in turn pivot-` ally and slidably mounted upon rotary member located above and on an axis con-` centric with that of the chuck; and suitable means are employed for moving said lever radially upon said rotating lmember, and for causing the roller thereon to travel` a path parallel with the periphery of the can body.

The Vrotating member comprises a wheel lever the edges of the clamp to form the As before stated the can body is held '55, mounted upon a shaft 56, depending from the overhanging bracket 4. Rotation is iniparted to the wheel by a belt 55, which connects it with a pulley5 upon the main drive shaft 5.

The wheel 55 is provided with two broad radially disposed spokes 56, 57, and two smaller ones 58. The spokes 56, 57, are slotted and carry respectively, slides 59, 60. These move in the same straight line and are connected by yokes 61, hence move to gether as a unit.

The slides are channeled as shown, and the bottom of the slide 59 is slotted as at 62. A screw 63,passing` through the slot 62, and into a block 64, adjustably secures the latter to the slide. It is to the block 64 that the lever which carries the Hanging roller is pivoted.`

t 65 indicates the lever. This comprises an upper pivot portion 66, an oHset portion 67, and a lower, roller carrying portion 68. It

is pivoted to the block 64 by a stud 70 and Ascrew 71. The lower, roller carrying portion `68of the lever 65 is substantially triangular in form; the offset Vportion 67 v being at an angle, the Hanging roller 50 depending from another, and a roller 72 extending upwardly from the third.

It will be noted that by adjusting the block 64 upon the slide 59, the roller 50 may be moved toward or away from the center of thewheel 55, according to the size of the can bodies to be flanged.

The roller 72 engages alcain groove 7 3, in the under face of a disk 74. The disk 74 is secured to the lower end of the shaft 56 by a screw or other suitable means, and isV keyed thereto to prevent rotation. The cam groove 7 3 is of such shape, as to cause the roller 50 to travel in a path parallel with the periphery of the can when the wheel 55 is rotated.

To throw the roller 50 into and out of engagement with the can body and chuck, recourse is had to thefollowing means. A lever 75 is pivoted above the slide 60, to a collar76which .rotates with the wheel At its upper end it is=provided with a nose 77, and its lower end is bifurcated, as at 78,

lto engage a pin 79,- extending across the groove in the slide 60. A cam 80 is slidably mounted upon the shaft 56 between the wheel 55 andthe bracket 4. This is operated by the aforementioned cani 21, through the lever 22. As the cam 21 rotates, the cam SQ is moved downwardly, engaging the nose of the lever 75 and rocking said lever, as shown in Fig. III. This moves the slide 60 inwardly, and as said slide is rigidly connected to slide 59, the latter is moved outwardly, carrying therewith the roller 50. After the can body is Hanged, the cam 21 raises the cam 80 and a pair of springs 81 return the slides to normal position, throwing the roller 50 out of action.

To regulate the pressure ol the roller 50. means are provided .tor adjusting the distance between the slides 5S) and (l0. Accordingly the yoke members G1 are attached to the slide 60 by an eccentric pin 85, and the end of the pin is kerfed, as at 86, ,to receive a suitable tool such as a screwdriver. By turning the pin 85 the distance between 'the slides may be nice y adjusted. A. clamp S7 secures the pin against turning after having` been set, and hence maintains the proper distance between the slides.

The operation of the machine is as follows: Assuming that the machine is at rest except that the belt is ruiming on the tast pulley, the operator places a can body in 'the chuck and closes the clamp thereupon. The chuck being at its lowest position at this time, the 'alse bottom is raised, so that when the can body is placed therein it rests upon said false bottom. TWhen the clamping members are closed and latched the can body is held snugly between them. He then depresses the lever l2 with his foot. This raises the chuck into position for cooperation with the roller 50, and also starts the machine in operation by throwing in the clutch in the manner hercinbefore described. As soon as the clutch is thrown in the worm and worm wheel begin to rotate, the latter carrying with it the cam 2l. `When the lug 9.1i on the bottom of the cam 2l has traveled a short distance, or out oit engagement with the lever Q5. it permits the latch 17 to engage the pin on the lever '13. This holds the clutch in operative position until the cam 2l makes a complete revolution, at which time the lug Qetagain trips the latch 17, releasing the clutch as described. As soon as the cam 2l starts to rotate, it lowers the cam 80, on the shaft 56, thereby throwing the roller 50 into operative position to flange the can body. he wheel. 55 is constantly rotating and carries with it the roller 50. so that when the roller is pressed against the can body it quickly makes several complete revolutions within it, turning both the top and bottom edges ot the can body outwardly over he clamping members of the chuck, forming neatly and accurately, the desired flanges. rl"he cam SO is held in its lowermost position during the entire time the can is being lianged, and rises again just previous to the time when the lug 24- operates to stop the machine. As soon as the clutch 1l is thrown out the brake shoe 28 impinges against a part on the worm sleeve and insures instantaneous stopping of the worm and cam, and unlatching the treadle, lowers the chuck.

Having thus described our invention, we claim as new and desire to secure by Letters Patent:
