In detail the'construction of the machine is as follows: y

The platen B illustrated in the drawings is provided with eight peripheral notches B; but I do not limit myself to the number of notches employed, as itis evident that a platen having more or less notches may be constructed. Each notch B' is circularly edged, and in each notch are screws or other means (see Figs. 17 and 18) for securing a rabbeted segmental clamping-ring B2, which has the .corners of the notch. In the upper portion ofeach clam pin g-ring B2 and preferably near the fronts thereof are arranged slidable clamping-dogs B3, pressed outward by springs B1, so as to project with their outer ends into a segmental recess B5, formed in the upper part of the ring B2 for the reception of the canhead, said dogs B3 being adapted to press upon the peripheral surface of a can-head, and hold it gripped to its seat. ring B2, near the lower portion thereof and at theinner face,isarrangedagroove B6,in which is held a spring B7, which projects outward on each side of the clamping-ring, the convex corners pressing upon the surface of a canbody to hold the same gripped in place, and thereby prevent the can-body from falling out of the notchwhile the platen is intermittently rotated. The intermittent rotary motion is given to the platen B by means of an intermittently-operating mechanism, shown `indetailin Figs. 15 and 16 and arranged as follows: On the upper end of the shaft BS, which carries the platen B and which shaft is mounted to rotate and to slightly move verticallyin its bearings, is `a spur-wheel N, in mesh with a pinion N2, secured on the upper end of a short shaft N3, journaled in suitable bearings in the frame A and carrying at its lower end a detent-wheel N4, formed in its under side with four radial recesses' N5 and at its peripheral surface with segmental .notches N6, as is plainly indicated in Figs. 15 and 16. The recesses N5 are adapted to be engaged by a friction-roller N7, journaled on the free end of In the clampingan arm NS, secured on a vertically-disposed shaft N, journaled in suitable bearings. on the frame A, and on the shaft N9 is-formed or secured a locking-disk N10, having a segmental notch in its peripheral surface for cngagin g the periphery of the wheel N1 (see Fig.j

16) at the time the friction-roller N7 travels in a recess N5. During the time the friction`l roller N7 is out of a recess the remaininnr eripheral portion of the disk N10 travels in a segmental notch N6, so as to prevent the detent-wheel N4 from accidentally rotating during the period of rest, The shaft N9 is rotated continuously and is provided for this purpose at its lower end with a bevel gear-l wl1eelN11, in mesh with a bevel gear-wheel N12, 'secured on the inner end of a shaft N13, journaled in the frame A .at the left side thereof, and said shaft N13 is driven from the main driving-shaft O of the machine, and which driving-shaft extends longitudinally and is journaled in suitable bearings in the lower portion of the frame A. The main driving-shaft O is provided at one end with the usual pulley O', connected by belt with other machinery for imparting a rotary motion to the main shaft O, and on the other end of said shaft O is arranged a pulley O2, (see Figs.

3 and 6,) connected by belt O3 with a large pulley O1, secured on the outer end of a shaft O5, journaled in suitable bearings in the frame A at the left-hand side thereof, and on this shaft O5 is secured a pinion O2, in mesh with a gear-wheel N14, secured on the shaft N in operation and the main shaft O is rotated then a rotary motion is transmitted to the shaft N13 by the action described and the rotary motion of this shaft N13 is transmitted to the shaft N9 by the bevel gear-wheels`N12 and N11, so that the arm N8, with its friction-roller N7, imparts an intermittent rot-ary motion to the detent-wheel N1, secured` onthe shaft N3, geared to the shaft BS ofthe platen B. The gearing described is so proportioned that when the main shaft O makes one revolution the platen B makes one-eighth of a revolu tion, so that a succeeding notch B' occupies the position the previous notch had, the platen being locked in position during the period of rest by the disk N10, the peripheral surface of which travels in a segmental notch N6 of the detent-wheel N4.

As previously mentioned, the shaft B13 has Itis evident that when the machine is rool IIO

arg-'O1 f .s

groove P1, engaged by a friction-roller B, journaled on the rear end of a transverselyextending lever B10, fulcrumed on links B11, hung on the frame A, and in the forked end of said lever B10 is carriedacollar B12, through which extends loosely the shaft Bs, and on the top of this collar rests aV collar B12, secured to the shaft B2. When the machine is in operation and the cam-shaft'P is rotated,

then during each revolution of the cam P2 a.l

swinging motion is given to the lever B10, so as to impart an up-and-down sliding motion to the shaft B2 and the platen B. Normally the shaft, with its platen, is in a lowermost position, and it is only raised for the crimping and compressing operation to bring the tops of the can-heads C against the under surfaces of the spindlesland l'. (See Fig. 7

The can-body-feeding mechanism D is next to be considered, special reference being had to Figs. 1, 2, 3, 4, 11, 12, and 13. This feeding mechanism Dis provided withaconveyer having a conveyer-frame D', in which is mounted to travel an endless belt D2, passing at-its inner end over a pulley D3 and at its outer end over a similar pulley. (Not shown.) The pulley D3 is journaled in a bracket D1, on which is also hung the inner end of the frame D', and said bracket D4 is fitted to slide ou a vertically-disposed post D5, (see Fig. 4,)-supported on the frame A to allow of adjusting the inner end of the conveyer up or down to bring the top run of the conveyor-belt D2 to a proper level relatively to the height of the can-body and the position of the platen B. The bracket D1 is adapted'to be secured in place after the desired adjustment has been made by a setscrew D, and said bracket is vertically adjustable by means of ascrew-rod D7, attached to the bracket and screwing in a nut D2, carried on the frame D', as is plainly shown in Fig. 4. On the lower end of the screw-rod D is secured a hand-wheel D9, adapted to be .taken hold of by the operator to turn the screw-rod and move the bracket D1 up or down on the post D5 at the time the setscrew D6 is loosened to make the desired adjustment, and when this is accomplished the set-screw DG is screwed up to permanently fasten the bracket in place on the post D5.

Through suitable slots in one side of the conveyor-frame D' project bell-crank levers D11,fulcrun1ed on the conveyer-frame and pivotally connected with each other by a transversely-extending rod D11, pivotally connected at its inner end with au arm D12, fulcrumed on a bearing A', formed part of the main frame A. A spring D11, connected with one of the bell-crank levers D10, serves to hold the same normally in an innermost position, as 'shown in Figs. 1 and 3, so that the can-bodies set vertically on the upper run'of the conveyer-belt D2 and traveling with the same are interrupted in their inward movement and held in position one behind the other and a suitable distance apart until'the bell-crank levers receive a swinging motion in an outward direction to allow the latter to travel forward with the conveyer-belt D2 until 'said bellcrank levers swing back to the innermost position to again interrupt the fo'rward movement of the cari-bodies. This movement of the bell-crank levers takes place simultaneously and at such time that a canbody can only travel inward from one bellcrank lever to the other before .its inward movement is interrupted, and this movement of the bell-crank levers takes place during each one-eighth revolution of the platen B. In order to impart the desired motion to the bell-crank levers by means of the rod D11 and arm D12, the latter is provided near its free end with an incline D12, adapted to be engaged by an arm Q', held on apusher-rod Q, mounted to slide longitudinally in the bearings A' A2. The left-hand end of the pusher-rod Q is provided with a head Q2, which is segmental in form to engage one side of the innermost canbody and push the same to the left over the conveyer-belt D2 and upon a table A2, supported by the 'frame A and arranged alongside the upper run of the conveyer-belt. The inner end of the right-hand side of the conveyer-frame D is formed with a curved guideway D15, reaching to the peripheral surface of the platen B to prevent a can-body from passing beyond the pusher-rod head Q2, and on the top of the table A3 is arranged an L- shaped guideway^A4 for preventing a canbody from moving in too ,far to the left when pushed from the conveyer-belt upon the table by the head Q2. The guideway A'1 extends with its inner end to one side of the front can be readily pushed into said notch and be engaged by the retaining devices therein for holding the can-body in position in the front notch of the platen B.

In order to impart a sliding motion to the pusher-rod Q, the following device is provided: The arm Q,which is adapted to engage the incline D13 when moving into an extreme left-hand position,extends downward and connects with a second rod Q`-, (see details in Figs. 1l, 12, and 13,) likewise mounted to slide longitudinally in the bearings A' A2. The lefthand end of this rod Q2 is pivotally connected by a link Q1 with a bell-crank lever Q5, fulcrumed on the frame A, and pivotally connected by a link QG with the lower end of a lever Q7, fulcrumed at or near its middle on the frame A, as shown in Fig. 12. On the upper end of this bell-crank lever Q7 is held a friction-roller Q2, traveling in a cam-groove Y 9, formed on one face of a cam-disk Q10, secured on the cam-shaft P, previously referred to. "When the cam-shaft P is rotated, the cam-disk Q12, by its groove Q2 and frictionroller Q2, imparts a swinging motion to the lever Q7, and the motion of the latter is transmitted by the link Q6, the bell-crank lever Q5, the link Q1, the rod Q2, and the arm Q' to the notch B in the platen B, so that a can-body` roo pusher-rod Q, so that the latter first moves to the left and then back to its former position. During the movement to the left the head Q1 pushes the innermost can-body from the con- 5 veyer-belt D? upon the table, as previously mentioned, and at the same time engages the incline D15, so as to impart a rearward swinging motion to the arm D12 to move the link D11 transversely and swing the bell-crankleio vers out of engagement with the several canbodies, so that the latter now travel -forward with the conveyer-belt, on which they rest until the bell-crank levers swing back to their innermost former position to interrupt the x 5 forward movement of the can-bodies.

In order to push the can-body from the table A3 rearward into the front notch B of the platen B, a segmental pushing-head R-is provided, which simultaneously operates with zo similar pushing-heads E' and L', of which the pushing-head E' serves to move a can-head from the can-head-feeding mechanism E to the can-head platen F, and the head L' serves to push the finished can from the platen B upon a guideway for carrying the cans over to one side of the machine, the said head L forming part of the ejecting device L, previously mentioned.

The special mechanism for actuating the 3o several pushing-heads R, E', and L is illustrated in detail in Figs. S) and 10, and is arranged as follows: The head R is secured on the upper end of a post R', attached to a slide R2, mounted to slide transversely in a guideway R3, attached to the frame A. The slide VR2 is pivotally connected with au arm of a bellcrank lever R?, fulcrumed on the main frame and connected by a link R5 with a lever R5, likewisefulcrumed on the frame, a 4o friction-roller R7 being on the left-hand side of said lever R5 to engage a cam-groove R5 formed on the under side of a disk-cam R, secured ou lthe lower end of the shaft N, previously mentioned, and forming part of the -intermittent driving device N. (Shown in Fig. 15.) Thus when the machine is in operation and the shaft N9 is rotated, as previously explained, then the canrdisk R9 imparts a swinging motion to the lever R5, which by 5o' the link R5 impartsa swinging motion to the bell-crank lever R1, so that the slide R2 is moved forward and backward and with it the post R' and the head R. The head E is held -on an arm E2, secured directly to the slide R2, so that this head moves in unison with the head R iu the manner described. The rear endiof the bell-crank lever R1 is pivotally connected with a slide L3, mounted to move longitudinally in a guideway L4, secured to I 6o the frame A, and ou said slide L3 is attached a post L2, which carries at its upper end the i head L' of the ejecting device L. The rock- -ing motion given to the bell-crank lever R1, as above mentioned, thus imparts a sliding n motion to the slide R2, as described, and also to the slide L5, so'that the head L moves lon-l gitudinally to-.push aiinished can from the platen-B at the rightfhand side thereof. As

shown in Figs- 1, 2, and 9, the post R' extends through a transverse'slot in the table A, and the latter is held vertically adjustable on 'posts A5 by means ofa screw-rod A5, screwing in the frame A, a hand-wheel A7 being at the lower end of said screw-rod to permit the operator to conveniently turn the latter and move the table A3 up or down on the posts A5. Set-screws A5 serve to fasten the table A3 in place on the posts A5 after the desired adjustment is made, it being understood that the table A5 is raised or lowered according to the level of the upper run of the belt D2 of the can-body-feed mechanism.

The can-head-feeding mechanism E is ar! ranged as follows: The disk E3 is mounted to rotate loosely on a pin E4, (see Fig. 14,) adjustably held on the main frame A, and on the under side ot said disk is formed or se.- cured a pulley E5, over which passes a belt E, also passing over a'pulley E7, secured on the shaft N9, previously mentioned, so that when the machine is in operation and they shaft N9 is rotated then a rotary motion is f transmitted by the pulley-E5 and belt E11 to the disk E3 to rotate the latter in the direction of the arrow b'. (See Fig. 1.) The forward right-hand portion of the disk E3 is flush with a table A9, formin g part of the main frame A, and the can-heads placed on this table are pushed by an operator upon the revol-ving` disk E3, so that the latter carries the canheads with it and under a shield or hood A10, secured to the table A'J and extending over the left portion as well as the rear end of the disk, as is plainly indicated in Figs. 1 and 2.

by a link E12 with a bell--crank lever E13,

fulcrumed ou the right-hand side of the hood A10, and this bell-crank lever is'provided with a downwardly-extending piu E11, 120925.--

which extends into the path of the can-body as the latter is pushed by the head Q2 0E 7 the conveyer belt D2 upon the table A5, adjacent to the guideway A1. Thus when the can-body is pushed over -upon the table Aa it moves in contact .with the pin E14, and thus imparts a swinging motion to the bellcrank lever E15, whereby said lever imparts a like motion to the link E12 and the bell-crank lever ES to swing the pin E9 outward away from the stop E11 and against the tension of the spring E10 to allow a can-head to move forward with the disk E3 and in front of the head E', then in a forward position. As soon as a can-body has moved past the pin E14.then
