SPECIFICATION forming part of Letters Patent No. 697,785, dated April 15, 1902.

Application filed June 14,1901. Serial No. 64,549. (No model.)

To all whom, it may concern:

Be it known that I, HENRY 0. BLACK, a citizen of the United States, residing at Oakland, county of Alameda, State of California, have invented certain new and useful Improvements in Can-Body Forming and Soldering Machines; and I do hereby declare the following to be a full, clear, and exact description of the same.

The present invention relates to a certain new and useful apparatus for forming what is known as a lap-seam can-body, the object of the invention being to deliver a canbody blank to suitable forming mechanism, whereby the said blank is curled or rolled directly around a seamer-h orn and to hold the can-body so curled or rolled upon the horn until the lap-seam thereof has been soldered, after which the soldered body is discharged from its seamer-horn, the invention comprising an intermittently-operated endless carrier having. a series of expansible seamerhorns secured thereon and carried thereby, with means whereby the can-body blank is rolled or curled upon the horn and gaged thereon, together with means carried by the seamer-horn and operated by the travel of the Fig. 3 is a broken diagrammatic View disclos-' ing the cam plate or rail, upon which rides the roll of the eccentric for expanding the seamer-horn during travel of the endless carrier, the seamer-horns being illustrated in dotted lines. the seamer-horns and its actuating-lever, the link of the endless carrier to which it is fulcrumed being in section. Fig. 5 is a top plan yiew of the machine from the flux-applying Fig. (3 is an roll to the discharge end thereof.

Fig. at is a detail view of one of enlarged end view in elevation viewed from the feed end of the machine, the carrier-disks being removed and the endless carrier being sectioned, the forward bracket for the forming-rolls being broken and the rolls being in section. mechanism illustrated in Fig. 6 of the drawings. Fig. 8 is an enlarged sectional end view taken on line 00 at, Fig. 1, and viewed from the feed end of the machine; and Fig. 9 is an enlarged top plan view of the soldering portion of the machine.

The frame of the machine consists of the standards or supports 1 2 and the side pieces 3 4. These side pieces preferably are formed of c11annel-iron,within the channel 5 of which work the rolls 6 of the endless carrier. The endless carrier comprises a number of link frames 7, united by link-pins 8, to the ends of which pins the rolls 6 are secured. The endless carrier works over end disks 9 10, secured to shafts 11 12, working in bearings of the supports2 1. In the periphery of each Fig. 7 is a top plan view of the feed disk semicircular seats a are formed, into which fit or rest the link-pins 8 during travel of the endless carrier.

The end disks 9 in the present case constitute the drive-disks for the endless carrier, being driven with a step rotation by means of cam 13, secured to one end of cross-shaft 14. This cam carries the rolls a a Fig. 2 of the drawings, which alternately work in and out of the slots 1), cut in the periphery of disk 15. Said disk is secured to cross-shaft 11, and to the same a step rotation is transmitted from the continuously-rotating shaft 14: by cam 13. To the opposite end of cross-shaft 14: is secured the gear-wheel16, which meshes with pinion 17, attached to cross driveshaft 18. Said shaft is driven by means of a belt (not shown) working over belt-wheel 19, at-

tached to the drive-shaft.

Inasmuch as connecting-pins 8 of the linkframes rest within the semicircular'seats of the disks 9 10, it is obvious that as the drivedisks 9 are driven by a step rotation an intermittent travel is imparted to the endless carrier.

To the endless carrier are attached the seaming-horns 20. Each horn is provided with a depending lug or tailpiece 20, which is fulcrumed between the shoulders 21 of the link-frame by pin 22. Being thus connected, the seaming-horn is free to move vertically upon its link-frame, its downward movement being regulated by set-screw 22, working I rail 27, Figs. 1, 2, 5, and S of the drawings.

This guide-rail extends the entire length of the machine through the center of the frame, being attached to the end supports of the frame and by suitable brackets throughout the length thereof. The forward and outer ends 27' and 27 are downward curved, so as to permit of the roi gradually entering therein to place the seamer-horns into horizontal position as carried toward the feed mechanism and to move off the guide-rail gradually at the discharge end of the machine.

The seamer-horns are hollow and cylindrical in shape and each horn is split longitudinally along one side, thus permittinga slight spring to the horn. Each horn is formed with two curved shoulders or shelves 28 28', which form a seat 29 for an eccentric cam 30. This cam is shaped to conform to the seat it occupies and is of such size as to approximately fill the seat when the seamer-horn is compressed to close the longitudinal open seam attached by suitable brackets to side piece 5 of the frame. As the roll 33 rides upon the inclined end 34 the crank-arm 32 is thrown or turned upward, which partly turns the eccentric cam edgewise within its seat 29, Fig. 8 of the drawings, and forces the split horn apart a slight distance or expands the same. The object of thus expanding the seamer-horn is to true the unsoldered canbody thereon as it is carried to the solderingirons, so that after being soldered it will fit loosely upon the horn after it has been contracted and slip therefrom as the horn is carried over the drive-disk. The horn is contracted or reduced in diameter after the canbodyhas been soldered thereon by the eccentric cam being restored to its normal position, Fig. 6 of the drawings, due to the roll 33 moving onto the downwardly-inclined end 34 ofthe cam-plate '35, Fig. 3 of the drawings, being gradually forced downward by the inclined plate 35, beneath which it is carried.

' Crank-arm 32 is likewise moved downward,

to speak, leaving the soldered can-body fit ting loosely thereover.

' To cross-shaft 14, Fig. 5 of the drawings, is attached the sprocket-wheel 37, which is connected to sprocket-wheel 38, Figs. 1 and '7 of the drawings, secured to shaft 39 by chain 40. To shaft 39 is attached pinion 41, which meshes with pinion 42, secured to longitudinal shaft 43. By this form of connection motion of the drive-shaft 18 is transmitted to shaft 43 for driving the endless body-blank carrier. This carrier consists of an endless chain 44, provided with a series of fingers, figures, or plates 45, located a distance apart equal to the width of the can-body blank. Said carrier is driven by the sprocket-wheel 47, secured to shaft 43, over which it works; The can-body blanks are placed upon this carrier one at a time between the projecting fingers or plates 45 and are carried thereby toward the inclined plate 48, over which the can-body blank is forced until its upper edge is placed between the forming-rolls 49 50. The length of the feed-plate 48 is slightlyless than that of the can-body blank. Consequently the edge of the blanks will be forced plates 45 being carried over the sprocketwheel 4'7.

The forming-rolls are driven by a belt (not shown) working over pulley-wheel 5l,secured to shaft of roll 49. To the opposite end of said shaft isattached a pinion 52,which meshes with pinion'53, secured to the shaft of roll 50. speed, and the moment the edge of the canbody'blank is received therebetween the same is carried between the rolls. As carried therebetween the body blank is guided down ward by guide-roll 52 and prevented from curling under or around roll by guard 53. The operation of the machine is so timed that a seamer horn 20 is at rest directly under the forming-rolls as the can-body blank is passed therethrough. As the body-blank leaves the forming-roll it gradually curls itself around This roll holds the can-body blank against the mandrel, and as it is a rotating roll, being driven by a belt (not shown) working over pulley 55, attached to its shaft, it assists in feeding the blank around the horn until the edges thereof overlap. By its own spring the can-body will firmly grasp the seamer-horn. The moment the can-body has been formed around the seamer-horn the endless carrier advances by an intermittent trayel toward the soldering mechanism.

,As the seaming-horn, with the can-body blank curled thereon, approaches the flux and soldering devices the roll 33 rides upon the cam-plate 35, so as to throw the eccentric cam within'the horn in order to expand same, as hereinbefore described. The horn, with its rolled can-body expanded, is carried below the flux-applying roll 56, which supplies-flux to the longitudinal seam of the can-body.

between the rolls 49 50 prior to the fingers or These rolls are driven at a high rate of the seamer-horn, being aided by the roll 54.

The ilux-wheel has an absorbent covering which receives the flux from supply-reservoir 56". After being fluxed the can-body is carried below the soldering-irons 57 57,

which are heated by a flame from nozzle 58, 4

directed into fire-box 58 of the irons. These irons bear upon the can-body seam as the same is moved thereunder by the intermittent travel of the endless carrier.

In order to guard against waste of solder, I have so arranged that the solder is not fed forward until a can is in position to be soldered. To accomplish this, the solder-feeding mechanism is operated by the can-body upon the horn. The wire solder 59 is fed against the face of soldering-iron 57 by the grooved feed-rolls 60 61, between which the wire solder is held, Figs. 1, 8, and 9 of the drawings. As these rolls are rotated the strip of solder is fed inward until its end bears against the hot iron, by which it is'melted and falls onto the seam of the can-body beneath the iron. Solder-feed rolls 60 and- 61 are secured to shafts working in bracket 62. To the shaft of roll 60 there is attached the ratchet wheel 63. This ratchet-wheel is engaged anddriven by pawl 64, carried by slide-plate 65, which lever is normally held pressed inward by spring 66. The inner end of said slideplate, which is outwardly inclined, Fig. 9 of the drawings, rests within a longitudinal groove or channel 68, cut in theside of each seamer-horn. During the travel of the horn in case a can-body is not thereon the said end of the slide-plate is held within said groove or channel by pressure of spring 66. However, as the horn is moved toward the soldering-irons with a can-body blank wrapped therearound the end of said slideplate cannot enter the groove or channel 68, as it is covered by the can-body blank held thereon. 'Such being the case, the slide-plate by the pressure of the traveling horn is gradually forced outward, causingthe pawl 64 to rotate ratchet wheel 63 a given distance, which in turn rotates the solder-roll and causes the inward feed of the solder. In this manner the feed of solder to the solderingiron is regulated by the movement of the canbody toward the soldering-irons, for unless a can-body is upon the seaming-horn the slideplate 65 will not be forced outward to actuate the solder-feed mechanism, but itsinner end will be held within the groove or channel of the scanner-horn.

Inasmuch as the eccentric expands the seamer-horn and holds the body while the horn approaches the soldering-irons, the lapped edges of the can-body are liable to separate too much or'spring apart. To obviate this and hold the same firmly down, the rods 69 areprovided. These rods-are attachedv to brackets 70,-Figs. l, 5, 8, and 9 of the drawings, and are so arranged that as the seamerhorns,-with the can-bodies, are carried toward and beneath the soldering-irons they bear against the can-body adjacent to the lap edges thereof and hold the same firmly pressed down upon its expanded horn.

As the seamer-horn,with the soldered canbody, is carried byond the soldering-irons by the intermittent movement of the endless carrier the eccentric cam 30 is thrown into position illustrated in Fig. 6 of the drawings by roll 33, moving beneath inclined plate 35, throwing crank-arm 32, as before explained, to restore the eccentric cam to its normal position. The split seamer-horn being thus re- 1eased,it willcontract byits own spring, leaving the soldered can-body fittingloosely thereupon.

During the travel of the endless carrier over the drive-disks 9 the loosely-held soldered can-bodies 7l slip from ofi the seamer-horn into discharge-chute 71, Figs. 2 and 5 of the drawings.

The under run of the endless carrier is supported by the rails 72, upon which the rolls 6 ride during travel of the said carrier toward the feed end of the machine;

Each seamer-horn is formed on its upper surface with a gage-shoulder 73, Figs. 6 and 8 of the drawings, against which the under edge of the can-body bears after being formed around the horn. This shoulder gages the can-body blank and prevents the rolled blank going beyond a given point around the horn.

It is possible that the body-blank may not be forced its full distance by means of the forming-rolls and roll 54,. To provide against the same and insure the under edge of the rolled body-blank bearing against the gageshoulder 73 of the horn, a second roll 74: is

employed, Figs. 1 and 7 of the drawings.

This roll is mounted upon the same shaft as roll 54 and bears upon the rolled can-body as carried beyond the forming-rolls by the intermittent travel of the endless carrier. By frictional contact with the rolled body-blank it forces the under edge of same firmly against the gage-shoulder 7 3 and trues the can-body upon the horn.

As the seamer-horns are carried toward the feed mechanism the roll 25 of fulcrumed lever 24 enters the groove on channel 26 of guide-rail 27 at its curved end 27 and causes the fulcrumed lever to gradually throw its seamer-horn into a horizontal position and to hold same so alined during its entire travel throughout the machine or until roll-25,moves from within the groove or channel.% at the downwardly-curved discharge end 27 of the guide-rail.
