Application filed August 19, 1911. Serial No. 644,949.

, ending machines especially intended for use in can factories, where one end. alone is ap plied, the other end of the can being left open for the application; of its head in the cannery, after the cans are filled.

My invention concerns a machine .of the.

double seaming type, in which the flanges of the can body and end are bent and doubled upon themselves by the pressure of properly grooved rolls.

The object of my invention is to provide a machine of this class in which the operation is a continuous one, effected during the continuous rotation of the machine, with no intervening periods of rest, whereby the capacity of'the machine is greatly increased.

The invention. consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which- Figure 1 is a plan View of my machine, the seaming-heads at the upper and lower positions of revolution being omitted. Fig. isa side elevation, the seaming heads and the clamping jaws at the side positions of revolution being omitted. Fig. 3 is a vertical section, enlarged, on the line A'B, of F 1, looking in the direction of the arrow. Fig. 4 is a section, enlarged, takeu on the line C D, of Fig. 2, looking in the direction of the'arrow. Fig.

5 is an elevation, enlarged, of the seam Flg. 6 1s a plan ing-head from one side. view of the same with the shifter head removed. Fig. 7 is an elevation of the same at right angles to the elevation of Fig. 5. Fig. 8 is a top view of one of the clamping jaws. Fig. 9 is a section on the line E-F, of Fig. 2, looking in the direction of the arrow. 10 is a vertical sectional view of the gearing for operating the main shaft and the seaming heads. Fig. ll'is a front elevation hf the carrier 11. The frame of the machine is composed of a stand 1, end plates 2 and a top bar 3, as seen in Figs. 1, 2 and 3. Secured to one side of the top bar 3 are brackets 4 which carry the angle irons 5 forming the vertically disposed can-body delivery chute 6. At one side of this chute, as shown in Fi s. 1 and 2, is the vertically disposed can liead delivery chute In 1, a can 8 and a canend 9 are shown in their respective chutes. Mounted in the end plates 2 of the machine frame is the. horizontally disposed main shaft 10. Uponthis shaft is keyed the combinedv oan-body and can-end carrier 11. As

shown in Fig. 3, this carrier is a disk formed with a plurality (here shown as four) of equidistant semicircular notches or pockets 12 in its periphery, which said notches, as shown clearly in Figs. 1, 2 and 11, are stepped or formed in three diameters; the smallest step or diameter 13 being adapted to receive the end of the can-body, the intermediate step 14 being adapted to receive the flange of said can-body end, and the largest step 15,being adapted t-o'receive the can-end. The position of the carrier 11 with respect to'the can-body and can-end chutes 6 and 7, as shown in Figs. 1, 2 and 3, is such that the lowermost of the vertical columns of bodies and ends rest temporarily upon the periphery of the carrier, as seen in Fig. 3, andthen, as the carrier revolves, they will drop by gravity into the notch or )ocket 12 which then comes intoplace, an Wlll seat themselves in their respective steps, as above explained; in which position the head and body are in alinement andready to be assembled. The carrier 11 thus supports and guides one end of the can-body. The

presser plate Wat this time moves against the end while it is in this position, and holds the end in the semi-circular disk whilethc can-body is being pushed into the end, then the pressersplate travels back in line of the double seaming rolls at the same time the jaws bring the can-body up; all of this moving of the plate 77 being doneby the cam 80. In order to support its other end, to

clamp it against rotation on its axis, and

to force it into its end, the following constructions are employed: Secured upon the main shaft 10 and rotating therewith is a four-armed spider 16, each arm of which at 'lts' extremity carries a bearing 17, n

which is mounted and adapted to slide in adirection parallel with the main shaft 10,

the stem 18 'of the clamping jaws. 'Each clamping jaw is duplex; the parts being complcmcntal and semicircular, one, des1gnated at 19, being a fixed member and the other 20 a movable one. This jaw 20' may be mounted on a slide, in a parallel line with the axis of the can or. at an angle thereto. Iir'the present illustration this member is so mounted as to swing. The swinging member is the outer' oneand is hinged to the stem 18 by means of the pivot 21 in a projection 22 of said swinging member, as is mostclearly seenin Figs. 1 and 8. Thus, the jaws are adapted to open and close by the swinging of one member from, and to, theother. When a jaw is in the lowest position of the revolution of the spider 16, this'swingingmember 20 is swung back, as seen in Figs. 2 and 4, and this open position of the jaw continum, as is shown in Fig. 4, until. it has passed the point at which the bodies and ends-are fed in, as may be seen by comparing Fig.4 with Fig. 3. As a re- 20 sultof this, the can body will be received in 1 the semi-circle of the fixed member of the jaw; it being'note'd that the jaws of the spider 16 and the notches of the carrier 11 e are in alinement in a direction parallel with the axis of the can. a

- After the can-body has been received by .the fixed member 19 of the jaw, the swing-- ing member 20 begins to close in upon the can-body, and when it has reached the upper point of revolution, said swinging jaw is fully closed, asseen in Figs. 2 and 4, arfd' the can body is tightly clamped and continues thus, as seen in Fig. 4, until relie'ved near the bottom position of revolution by swinging ,open the member 2() whereupon-the can with its assembled and seamed end falls out of the fixed memberby gravity and is delivered tothe discharge runway 23.

With this brief outline of the operation of the jaws, the mechanism for eifeetin such operation will be readily understoo On ;-the back of the projection 22 of the swinging jaw-member is a stud and roller 24. Referring now to Fig. 2, a standard 25 is secured to the frame stand 1 and to this standard is secured a grooved cam 26 which,

. as seen in Fig. 4," is concentric with the axis.

ofthe spider 16 from the lowest portion of revolution up through an are past the point of can entrance and nearly to the upper position of revolution then the cam begins to twist, as shown in Figs. 1 and 4 at 27, until the top is reached, when it has made a quarter turn. The bottom end of said cam also has aquarter twist, but is broken away as shown at Fig.4, andjwill be explained later. As the roller 24 on the projection 22ofthe swing in'gjaw-member .20 .moves along the cam 26 near itslower end, as seen in'Fig.

2, the twisted part being cutaway, and as indicated in dotted lines in. Fig. 4, travels upward .in the concentric, portion of the cam, causing the 'jaw-member.;2 0 to remain $5 open. After the can-body'hasbeen received in the fixed jaw-.memben19, the roller 24, "reaching the twisted portion '27 of the cam 26 and traveling therein, causes :the swinging jaw-member 20 to close upon the can, so that when the top is reached the can-body is clamped between the two jaw-members. Now, in order to positively hold the swinging jaw-member 20 closed during the other half of the revolution, there is a roller 28 on the back of said jaw which, as seen in Fig. 4, enters behind and is held by a fixed lard rail 29 secured to the'top bar 3 of the rame of the machine, which rail extends concentric'with the axis of the spider 16 down to a point near the bottom, where at 30 it terminates, as the roller 24 enters the twisted lower end of the cam 26, thereby swinging jaw 20 into an open position, as seen in Fi s. 1, 2 and 4.

when the can-body has been clamped by the jaws, it is pushed bodily in the line of its axis, so that, sliding in the notch 12 of the carrier, it enters the end 9, and both can-body and loosely fitted end, held firmly between'the clamping jaws and the presser plate, are pushed still farther until the end of the body and its end are free of the car- .rier and are in position to be acted uponby the seamer rolls. This pushing forward of the body and end is efi'ected, by causing the clamping jaws to slide forward. As has been. previously stated, the stem 18 of the jaws 1s slidably mounted in a bearing 17 on the extremity of the arm of the spider 16.

' To prevent any tendency to rotation, the fixed jaw-member 19, as shown best in Fig.

8, is fitted with two side rods 31, extending parallel with the stem 18, and the other ends of said rods and said stem are united in a cross head 32. The bearing 17 is provided 5 with ears 33', through which the side rods 31 pass and in which they slide. The cross head 32 is fitted with a roller stud 34 which,

as shown in Figs. 1 and 2, travels in a cam 35 secured to the end plate 2 of the machine 1 frame. This cam is fashioned to push forward and to retract the clamping jaws at proper times.

' 36 arethe seaming heads. There are four of these, corresponding and in line with the 1 5 carrier notches 12 and the clamping jaws 19 and 20. Each head is provided with a pair of grooved seaming rolls 37 adapted to be thrown into .action to ress upon the flanges of the assembled end and can-body, and "double seam them in a manner now well known. These heads revolve asa series about the axis of the horizontal main shaft andwith'said shaft, and'in unison with the carrier 11 and the series of clamp- 125..

.' Referring to Figs. 10 and 2, 4:1 is a power shaft, having a pulley 42 and a clutch 43. Upon the power shaft is a small gear 14 which meshes with a large gear 45 on the main shaft 10, whereby said shaftis driven at relatiyety low speed but with continuous motion. Upon the power shaft 41 is also mounted a' large gear 46 which meshes with a small gear 47 on one end of a sleeve 48, which is loosely mounted upon the main shaft and is rotatable thereon. The other end of this sleeve 48 has a large gear 49,

which meshes with a small gear 50 upon each of the shafts 38 of-the seaming heads- 36. Thus a relatively fast rotation is imparted to the seaming heads. In order to stiffen the support of the seaming-head shafts 38, there is another spider 51, which is .loosely mounted upon the sleeve 48. In the arms of this spider the shafts 38 are also journaled, and said spider isoonnected with the main spider 40 by yokes 52.

In order to throw the seaming rolls 37 of the heads 36 into and out of action, the parts are constructed as follows Referring to Figs. 5, 6 and 7, in the seamer head are two oppositely mounted rock shafts 53 passing through the head. The ends of these shafts which projectfrom the face of the seamer head have cranks 54 in the ends of which seaming rolls 37 are mounted. The other ends 0 the rock shafts 53 have cranks 55.

i The seamer head has side brackets 56, in

which are journaled rock pintles 57. On these rock pintles are secured cranks 58; the ends of which are-forked over studs 59 projecting from lugs 60 of sleeves 60, which sleeves are mounted to slide in bearings 59' on the head 36. Passing through the sleeves thrown out to their work and again withdrawn therefrom, and the limits of their throw may be varied by, adjusting the nuts 57 on the rods 58. To' rock the pintles 57 there is a. shifter head tilfeathered upon the shaft. 38 of the securing head, said shifter head having on oppositesides the ways 62.

I In these ways, as seen in ifig. 5, play rollers 63, secured to cranks 6 l which are secured upon the pintles 57. \Vlien this shifter head is moved along the shaft 36, which carriesi't,

it will rock the pintles 57.

To shift the head 61', the following connections are made: Referring to Figs. 2 and clamped.

9, 65 is a gear which is loosely mounted on the main shaftlO, and has connected with it a cam 66. Shifting levers 67 are pivoted at 68 to brackets 69 secured to the spider 40.

These levers have forks 70 at one end, which engage an annular groove 71 of the sh) .1

; head 61. The other ends of the levels. have roller studs 66 which play in the cam 66. If now the cam 66 be held against rotation, the shiftingtlevers 67, revolving as they do, will beswungon their pivots 68, and will thereby move the shifter head 61 back and forth. To thus hold the cam 66 against rotation, by which. is meant relative rotation,

there is a shaft 72, which passes from one endot the machine through-the spider 16,

as seen in Fig. 4;, and through a hole 11 in the carrier 11, and is mounted at its other end in a bearing 73 secured to the fm ain shaft 10. This shaft 72 has at its outer end a gear 74 which meshes with a stationary gear 75 fixed upon the machine frame. At

.its other'end the shaft 72 has a gear 76 which meshes with the gear 65 loosely mounted on the main shaft 10, and which has fixed to it the cam 66. It will now be seen that by properly proportioning the gears 65, 76, 74 and 7 5, the gear 75 being a stationary one, the effect will be to hold the loose gear 65 in a fixed relation to the gear 75, which relation is a relatively stationary one. Thus, the cam 66 is held fixed.

77 is the presser plate which moves up against the end and holds it firmlyin the plate 11, while the can-body is being pushed into it. It is then timely moved back in unison with the clamping jaws until the canbody and end are in a position for the seaming operation. The plate 77 is carried by the stem 78 which is slidably mounted in the seamer head shaft 38 and projects from the outer'end of said shaft. A stud and roller 79 are mounted on the projecting end of the stem and play in acam 80 carried by the end plate 2 of the machine frame.

The machine operates as follows: The oporation is a continuous one in contradistinction to an intermittent motion in which periods of rest are provided to allow time for certain functions to be performed. The clamping and the seaming devices accoinpany the cans and perform their functions while traveling. The can-bodies and the can-ends roll by gravity into successive notches 12 of the carrier 11, and are therein rest upon the fixed clamping jawmemhers 19. Then the swinging jaw-members 26 come intoaction and the can-bodies are Then the clamping jaws are moved .lineally and the can-body is forced into the end and both can-body and can-end are moved still further to a position for the operating parts 'are' traveling, and near. the completion of the-{cycle the cans are released and drop out byfgravity. The presser' plate '77 performs threefunctions: F rst, it forms I a guide for oneside fof the-end as it drops from the 'chute 'into' the-carrier notch 15.- Second, after thefendhas-dropped into the notch 15, the plate moves into the end, holding it in place until the can-body is'assembled ,withthe end. -.Third, it moves back with the end until the end. and can-body are in-line wvit-htlie's'eamin rolls and holds the end firmly inplace whi e it f is being seamed onto the body a Having thus described my invention, what.
