CAN-SEA'MING OR LIKE MACHINE SPECIFICATION forming part of Letters Patent No. 673,720, dated May 7, 1901.

Application filed'March 26, 1900 Serial No. 10,253. (No model.)

To all whom, it may concern-.-

Be it known that we, CONRAD FIELD MEND- HAM, ERNEST FEATHERSTONE GRIFFIN, and WALTER EDWARD HIGGS, subjects of the Queen of Great Britain, residing at London,

England, have invented certain new and useful Improvements in and Relating to Can- Seaming or Like Machines, of which the following is a specification, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation, Fig. 2 a rear elevation, and Fig. 3 a rear elevation with parts removed, of our improved can-seaming machine. Fig. 3 is a partial side elevation illustrating the operation of ourimproved machine. Fig. 4 is a plan illustrating a detail of construction. Figs. 5 6, 6, 7, 8, and 9 are diagra ms illustrating the successive stages in the formation of a joint or seam.

Like characters indicate corresponding parts throughout the drawings.

Our invention relates to can-seaming and like machines, and is chiefly designed to enable such machines to act automatically and rapidly, so as to permit a large output, while obviating any risk of danger to the attendants.

An important feature of our said invention consists in that the bodies of the sheet-metal boxes or cans are flanged up, the ends pressed on, and the joints double-seamed all in one operation. For this purpose the cylindrical can-body, with the ends loosely placed in posilion thereon, is received between two suit- 5 ably-formed and fast-rotating chucks. As

the tin revolves between the said chucks suitably-formed spinning wheels are moved automatically into contact with the body and operate in such a manner as to throw up the necessary flanges. The process is further accelerated by the rotating chucks closing up together by an amount equal to the depth of the flanges at the precise momentthe flanges themselves commence to form. The flanges being thus made, the spinning wheels continue to advance and by this action slightly curl the edges of the ends of the tins. This done the wheels withdraw, and two others, also specially shaped, come into play and conti'nue the spinning action where the former ones left off till the ends and the flanges on fianging and curling. driven by independent belts, the speed varythe body are curled up together, forming what is known as a double'seam joint. These latter wheels now retire, and the chucks slide apart, releasing the tin, ready for the next. v The rotation of the tin by means of the said chucks is quite distinct from the operation-of. The two chucks are.

ing according to the diameter of the tins it is required to make.

According to another part of our invention we provide improved means whereby canbodies, drums, or the like can be automatically and rapidly tranferred from one place to anotherfor example, from an inclined chute or way, onto which they are placed by hand, into position between the rotating chucks above mentioned-or they can be employed for analogous purposes in can-work- 7o ing machinery. For this purpose the apparatus consists chiefly of a hanging arm which by an arrangement of shafts, cranks, and cams receives two principal movementsviz.,

a swinging or-pendulum motion from one cam and a vertical reciprocating action from the other. By a suitable combination of these motions the lower end of the arm, which is provided with a suitable hand for grasping the tin, can be made to pick up the boxes8o from some convenient source of supply and rapidly deliver them into the seaming or other machine. To further insure positive action 1'. e., that each tin shall be delivered to exactly the same-positionthe cam-rollers are brought to rest on special adjustable stops when the tin is in the position to be grasped by the machine. It is further carried out in the design that in the event of the machine refusing to discharge the finished tin at the 90. proper moment this apparatus cannot become deranged by the tins colliding. The rollers on the cam-paths above referred to are held down by hanging weights, which in the event of any undue resistance to the arm either in swinging, lifting, or lowering are simply raised up, as hereinafter described. This is a feature of special safety.

The apparatus is adjustable throughout and maybe made to handle any size tins or IOO drums. It can further be used in either vertical or horizontal positions. Our said invention, moreover, comprises other improvements hereinafter set forth.

Referring to the drawings, a is the frame of the machine.

I) c are head-stocks adapted to slide on guideways d on the frame a and hearing chucks e f on their mandrels, which are driven by means of belt-pulleys g. The chucks ef are of suitable form to engage with the ends of the cans to be made and are provided with spring-controlled presser-pads h in their end faces for automatically freeing the finished cans from the said chucks when the headstocks are moved outward, as hereinafter described.

The inward motion of the head-stocks b c to engage the can and the outward motion thereof to release the said can are obtained by means of a cam-groove j, formed in a drum on the main shaft 75, to which rotary motion is imparted by means of spur-wheel reduction-gearing from the driving-pulley Z. In the cam-groove j works a roller m, mounted at one end of a sliding bar 71, the other end of the said bar being secured to the lower part 0 of the head-stock c, which is adjustably secured to the upper part c by means of a nut o and leading-screw c The bar n is, moreover, provided with a sleeve, which is adjustably secured thereto by means of a setscrew or other suitable means and bears a knife-edged projection 19. This projection 19 is adapted to engage with the lower arm of a double-armed lever q, pivoted at 'r in the frame a and having its upper end pivotally connected to a block 8, which is adjustably secured to the head-stock b by means of a leading-screw 6. When the bar n is moved to the left, Figs. 2 and 3, the head-stock 0 will be carried with it, and at the same time the head-stock b will be moved to the right by means of the lever q, thus bringing the chucks cf together. The chuck fis moved outward again by means of the bar n, and the chuck c by'means of a spring u, resting at one end against an adjustable stop 1; on the frame a and at the other against the block 8.

The spinning rollers a; for acting on the ends of the can y are rotatably mounted on carriages 2, which are adapted to slide on brackets or frames 1 2 and are adjustable thereon by means of nuts and leading-screws 3. The brackets 1 2 are mounted on a rockshaft 4, which is supported in suitable bearings on the frame ct, the bracket 2 being adjustable longitudinally along the shaft 4, for which purpose it is secured thereto by means of a set-screw 5,engagin g with a slot or groove 6 in the said shaft.

In order to bring one or other set w a: of spinning rollers into engagement with the can or to hold both sets out of engagement therewith, as required, the bracket 1 is provided with an arm 7, which is connected by links 8 to an arm 9 on a second rock-shaft 10 in such a manner that the distance between the axis of the shaft 10 and the axis of the joint between the links 8 and arm 9 can be adjusted by means of a nut and leadingscrew 11. The rock-shaft 10 is actuated by means of an arm 12, which bears a roller 13, engaging with a cam-groove 14 in the inner side of the drum on the main shaft It. By adjusting the head-stocks b o, the bracket 2, the carriages z, and the link 8 as above described the machine can be arranged to work on cans of any desired length and diameter within given limits.

15 is an inclined chute onto which the canbodies with the ends loosely fit-ted therein are placed .and to the bottom of which they successively roll by the action of gravity. This chute is pivotally mounted on brackets 16 and can be secured at any desired inclination by means of set-screws or other clamping devices acting upon quadrants 17. The height of the brackets 16, and therefore also of the lower end of the chute 15, can be adjusted by raising and lowering the studs supporting the brackets 16 in the slots 18 in the frame a.

In order to transfer the can-bodies y from the lower end of the chute 15 into position between the chucks e f, we employ our improved feeding or transferring device, which comprises a spring clip or hand 19, formed of elastic sheet metal of suitable width of aperture and diameter to readily slip or spring over and retain the can-bodies y to be worked. This hand 19 is detachably secured, by'means of a set-screw 20, to a rod 21, which is adapted to slide longitudinally in a sleeve 22, mounted on a rock-shaft 23. The upper end of the sleeve 22 is of smaller diameter than the remaining portion and is adapted to be engaged by the stop-nuts hereinafter described. The shaft 23 is provided with an arm 24, connected, by means'of a link 25, to one arm 26 of a bellcrank lever 26 27, which is capable of turning freely on the shaft 23, the link 25 being made in two parts connected by a turnbuckle 29, so as to permit adjustment of the limiting positions of the sleeve 22. The arm 26 is drawn downward by means of a weight 30, pivotally connected thereto, its lowermost position being determined by means of an adjustable stop 31. The upward motion of the arm 26 is effected by means of a cam 32 on the cam-drum acting on a roller at the end of the arm 27 of the said lever. By these means the sleeve 22 will be oscillated between the extreme positions indicated in dotted lines in Fig. 3

The motion of the rod 21 in the sleeve 22 is effected by meansof links 33, pivotally connected to a cross-head 34 at the lower end of the said rod and to arms 35, mounted on a rock-shaft 36. The shaft36 is actuated by means of an arm 37 and a link 38, provided with a turnbuckle 39 for adjusting the limiting positions of the hand 19, from an arm 40 on the shaft 28, which shaft is itself controlled by an arm 41, having a roller at its end for engaging with a cam 42 on the cam- IIO drum, and by a weight 43, pivotally a tached to the arm 40. A further adjustment for limiting the downward travel of the hand 19 is provided by a stop consisting of lock-nuts 44, secured on the screw-threaded upper end.

of the rod 21 and adapted to engage with the upper end of the sleeve 22 when the hand 19 is in its lowermost position.

The operation of our improved machine is as follows: Assuming the roller m to be in the part of the cam-groove j at which the chucks are moved to their farthest distance apart, as shown in Fig. 2, the hand 19 in the position shown in Fig. 1, and the chucks e f to be rapidly rotating at equal velocities, the head-stocks b c are first moved together, so as to firmly grip the can between the chucks ef, and the hand 19 withdrawn by raising the rod 21 in its sleeve 22. The spinning wheels to are then brought into engagement with the ends of the can, as shown in Figs. 5 and 6, to form flanges on the body thereof, the chucks cf being simultaneously moved further togelher to facilitate the formation of said flanges. The frames 1 2 are then oscillated, so as to bring the spinning wheelsw out of engagement and the spinning wheels 00 into engagement with the said can. The operation of forming the joint is effected as follows: The parts being-in the position shown in Fig. 5, the spinning wheels to are caused to act on the periphery of the cylindrical body y of the box or can near the edge thereof, while the chucks cf, Fig. 3, with thefianged heads y, are simultaneously brought together by the means above described, so as, to curl over the end of the can-body y, as shown in Fig. 6, the wheels to meanwhile sliding longitudinally on their axes against the pressure of suitable springs z. The brackets 1 and 2 then rise sufliciently high to allow the wheels to to clear the flanges on the bottom and top of the can, and the springs 2 return the wheels to to their former position against the slides z of the brackets 1 and 2. Having accomplished this, the cam-groove 14 causes the brackets land 2 to again descend and the wheels to to engage the edge of the flange on the top and bottom of the'can, as illustrated in Figs. 6 and 7. The brackets 1 2 are then rocked, so as to remove the wheels to from contact with the seam and to bring the spinning wheels m into engagement therewith, as shown in Fig. 8, so as to com plete the joint, after which the wheels 00 are withdrawn, as shown in Fig. 9, and the can ejected by the presser-pads h after separation of the chucks cf. The hand 19 is again raised, as shown in Fig. 3, and the sleeve oscillated until it approaches the position shown in Fig. 1,when the hand 19 descends and places the fresh can in position between the chucks ef, which have in the meantime moved apart to release the finished can, the frames 1 2 being simultaneously moved into their mid-position, where the spinning wheels w 50 are at equal distances from the axis of the chucks e f, Fig. '9. The said chucks now move inward to seize the fresh can, and the spinning wheels 20 move into engagementwith the said can, after which the above-described opera tions are repeated as often desired. The chute 15 is kept supplied with unseamed cans, while the finished cans fall into a chute or other suitable transferring device, whereby they are conveyed into any desired position.

It will thus be seen that the machine works quite automatically and the attendant runs no risk of personal damage in supplying the I cans to or removing them therefrom. Moreover, by arranging the levers 26 40 so as to be brought to rest by adjustable stops 31 44 when the hand 19 is in its delivery position to hold an unseamed can between the chucks efwe are enabled to insure that the tin, can, or the like shall always register accurately with the said chucks.

Another advantage of our improved machine consists in that there is no risk of damage being caused to the machine or to the cans in the event of any jamming taking place, since the positive motions of the hand -19?l. e., those produced by the arms 27 41 being pressed away from the shaft by the cams 32 42are those which take place in a direction extending away from the chucks ef and in an upward direction, wherein the hand 19 would be pulled off the can in the event of the can being arrested. The downward and inward motions of the hand 19 are all effected by the action of gravity on the weights 30 43, so that if there should be any obstruction vone or both of the said weights would remain lifted and the roller on the corresponding arm or arms 27 41 will be kept out of contact with its cam or cams 32 42, and thus damage to the machine or to the can prevented.

It is obvious that the spinning wheels can beof any suitable form and number and that. the order of the several operations can be modified without departing from the nature of our said invention.
