. To all whom it may concern.-

Be it known that I, EDWARD J. DOLAN, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Oan-Making Machines; and I do hereby declare the following to be afull, clear, and exact description of theinvention,such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings and letters of reference marked thereon, which form a part of this specification, and in which-- Figure l is a side elevation, partly broken away. Fig. 2 is a plan. Fig. 3 is a front end view, shown partly in section. Fig. 4 is a rear end view, partly in section. Fig. 5 is a longitudinal section through the main shaft. Fig.

6 is a horizontal section on the line xx of Fig. 5. Fig. 7 is a detail View of the plunger. Fig. 8 is a cross-section on the line 3 y of Fig. 6. Fig. 9 is a cross-section on the line 2 z of Fig. 6. Fig. 10 is a detail of trimmingrollers.

This invention relates to can-making machines, and has for its object to form a complete can automatically in the one machine.

The invention consists in the peculiar combinations and the novel construction, arrangement, and adaptation of parts, all as more fully hereinafter described, shown in the accompanying drawings, and then sought to be specifically pointed out in the claims.

Referring to the drawings by letter, A designates the frame of the machine, 13 the main shaft, and O a driving-pulley thereon, and to which motion may be imparted from any suitable source of power.

Upon the opposite end of the shaft'B is a beveled pinion, a, meshing with the beveled pinion 1) upon the upper end of the vertical shaft D, which is journaled in suitable brackets, a, upon the firame and carrying upon its lower end the beveled pinion c.

E is a horizontal shaft suitably journaled near the bottom of the frame, and carrying upon one end a beveled pinion, d, meshing with the pinion c on the shaft D, and at its other end the beveled pinion e, meshing with the beveled pinion f, carried upon the lower end of the shaft F, which carries at its upper (No model.)

end the beveled pinion g, which in turn meshes with a beveled pinion, g, on the shaft G. Thislatter pinion meshes with the pinion h, carried by a vertical shaft suitably journaled in the brackets h on the frame of the machine, and carrying at its upper end the beveled pinion j, meshing with the beveled pinion on the horizontal shaft H, which is suitably journaled in the frame and carries near the center of its length the beveled pinion k, meshing with the beveled pinion Z on the vertical shaft I, which carries at its lower end the beveled pinion m.

J is a transverse shaft carryingloosel y upon one end a beveled pinion, n, meshing with the pinion m, just described, and Jis a shaft carrying at one end the pinion n, meshing with the pinions c and d, as shown in Figs. 1 and 4.

Suitably journaled at the front end of. the machine are the trimming-rollers A A, provided near their outer ends with cutters a", which trim the sheet of tin to the proper width as it passes between them.

B is a roller suitably journaled at the rear of the trimming-rollers, and b is a suitable roller journaled at the rear end of the machine.

B is an endless belt passing around the outer ends of said rollers. Motion is imparted to said belt by means of the belt 0, passing around the roller B and a roller, 0 on the shaft Gr.

D is the seaming cylinder, around which the blank is formed and seamed in any suitable way. One convenient means is shown in Fig. 4, in which (1 is the blank; D, the cylinder; E, E", and E", upright bars operated by cams on the shaft E. The pushing bars E E are provided with friction-rollers 6 a respectively. The bar E has a convex bearingsurface, E, to accommodate a portion of the circumference of the cylinder D.

F F are convexjaws or wings hinged upon opposite sides of the bearing E, which, when the bars E E are forced upward, clamp the blank around the cylinder, after which the seaming is done in the following manner: The cylinder D is providedupon its upper surface with an oblique recess or die, 1, and the plunger 0 carries the follower 2, which, when it descends, forces the blank into the recess or die 1, the shape of which it then aslength, the stop 1* is withdrawn and the sheet sumes. The shafts of the rollers f are pivfolded to form the scam the plunger G is caused to ascend by means of springs (not shown) arranged within the bearings, whichniovement of the plunger, through the medium of the links H H, forces forward the plunger H on the end, of the horizontal rods H. The cylinder D is formed with longitudinal recesses 3, from which project the springs 4, which serve to pressagainst the edge of the rear end of the body of the"box, and in the further movement of the plunger H the box is forced forward upon the crimping-cylinder I, where the crimping on of the bottom is done.

1 are idle crimping-rollerscarried by the plunger 1 which is provided with a frictionroller, 1?, and operated at proper intervals by the cam l on the shaft H.

Motion is imparted to the shaft J from the shaft H by means .of the pinions k Z, shaft I,

and pinions m n.

The shaft J is adapted to be moved longitudinally forward at proper intervals by means of the cam K upon the shaft G. The portion J, which is a section independent of the re- 'mainder of the shaft, is prevented from revolving by means of a longitudinal groove, 7' upon its outer surface, which engages with a corresponding pin upon the inner surface of the journal-box within which it moves. The return of the shaft, after the same has been moved forward by means of the cam K, may be provided for by any suitable arrangement of springs, as 3', adapted to accomplish the purpose. The end J" of the shaft J is provided with points or projections 0 0, adapted to engage with corresponding recesses in the end of the cylinder 1. This construction is clearly shown in Fig. 5.

In operation the sheet of tin from which it is desired to construct the body of the box is passed between the cutting-rollers A A ,.where it is trimmed by the collars or cutters 0; to the properwidth. From this point the strip passes between the friction-rollersp p and is carried to the knife noperated by means of the cam 1" upon the shaft J. m is a beveled pinion loose on the shaft J and formed integral with the cam r, the object of which construction will be hereinafter described. The sheet is caused to stop at the proper point by means of the stoppingpin 1", which is forced upward by means of its engagement with the cam 7' upon the shaft E. The tin sheet having been cut to the proper continues its course between the friction-rollers until it reaches a point directly'beneath the seaming-cylinder D, around which it is bent and the edges seamed, as heretofore described, and is thence forced forward upon the cylinder 1 by the mechanism above described provided for this purpose. r is a stopping-pin operated by the earn 1" on the shaft E, which cam is so arranged as to project the said pin at proper intervals to stop the one upon the other, and allow one of said sheets to be bent around the cylinder D be- A circular piece of tin of suitable size to form the bottom of the can is placed over the end J of the cylinder J, where it is held by the projections 0-0 of the shaft J, and with the next successive forward movement of the shaft J it is securely clamped against the end of the cylinder 1 and held securely in position by means of the projections 0 0 upon the end of the shaft, J The crimping-rollers I are then forced downward, and the roller at the right of the machine, engaging with the edge of the disk of tin thus held in place against the end of the cylinder, serves to securely crimp the same in place, thus forming the bottom of the inder J, although this latter roller is not necessary, and may he sometimes omitted.

In order that the shaft J maybe stoppedin its revolution, so as to secure an engagement of the points 0 with the corresponding openprovided, which is caused, by reason of its enenter a hole, 8, in the upper surface of the shaft, J At the time of such engagement of the pin s with the hole s the forward movement of the shaft J causes the beveled portion the clutch .9 thus causing it to rotatewith the pinion n, which is in engagement with the pinion m on theshaft I'.

The construction and operation of this clutch mechanism will be best understood by referring to Figs. 1 and 5;in which it will be seen that the portion a is formed integral with the shaft J, and of course revolves with it, while the pinion 11, carrying the clutch s, the beveled pinion w, and cam r, are sleeved loosely upon said shaft. The beveled pinion a: is formed integral with .the cam r, as clearly shown in Fig. 5. When the shaft J' is forced forward by the cam K, the beveled portion .9 engages the-clutch 3 causing said shaft to revolvewith the pinion n. The engagement of the beveled pinion on with the pinion m causes the cam 1" to actuate the knife 1' at proper intervals.

The bottom of the box having thus been securely clampedin place, the pin sis disengaged from its engagement with the shaft J 5 by means of a spring, (not shown,) and at thesame time the beveled portion 8 of the shaft is, by means ,of the spring mechanism heretofore referred to, withdrawn from its engagement with the clutch s, and the beveled pinion n being again thrown into engagement with the pinion m, the shaft is allowed to revolve, and the bottom of of the idle-roller I The box which has thus sheets of tin and prevent them from crowdingfore the next sheet reaches the bending-jaws.

can, and the other roller, 1 serves to prevent the can-bodies from being forced from the cylgagement with the cam s on the shaft H, to

ings-inthe end of the cylinder I, a pin, 8, is-

s of said shaft J to frictionally engage with f the can is crimped securely in place by means been completed still remains upon the cylinder I, and is removed therefrom by means of an attachment to the shaft J, which is clearly shown in Fig. 5 of the drawings.

T represents flat strips of spring metal, one of which extends along upon each side of the shaft J, within suitable grooves formed in the bearing, as shown in Fig. 8. The end of each of these spring-strips T is provided with hooks adapted to spring down over the edge of the can. The can being thus grasped by the springstrips T, the box is drawn off from the cylinder 1 by the return movement of the shaft J, as will be readily understood.

Having thus described my invention and set forth its merits, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, with the trimmingrollers and forming and seaming devices, of

an endless carrier arranged between said trimming-rollers and forming and seaming devices, and a vertically-operating knife arranged to dividethe sheet into proper lengths as it passes over said carrier, substantially as described.

' 2. The combination, with the trimmingrollers and forming and seaming. devices, of an endless carrier arranged between said trimmingrollers and forming and seaming devices, a vertically-operating knife arranged to divide the sheet into proper lengths as it passes over said carrier, and a stop arranged in advance of said knife, substantially as and for the purpose specified.

3. The combination, with the trimmingrollers and forming and seaming devices, of an endless carrier arranged between said trimming-rollers and forming and seaming devices, a vertically-operating knife arranged to divide the sheet into proper lengths as it passes over said carrier, and two stops arranged between said knife and the forming andseaming devices, substantially as and for the purpose specified.

4. The combination, with the cylinder I, of a vertically reciprocating plunger, an idle crimpingroller carried thereby, and a horizontally-reciprocating bottom clamping device provided with means for removing the finished can, substantially as described.

5. The combination, with the cylinder I, of the plunger 1 provided with friction-roller t the idle crimping-roller 1 carried by said plunger, the shaft H, and the cam I on said shaft, substantially as and for the purpose specified.

In testimony whereof I affix my signature in presence of two Witnesses.
