MACHINE FOR QPERATING ON SHEET-METAL VESSELS.

SPECIFICATION forming part of Letters Patent No. 586,661, dated July 20, 1897.

Application filed November 23, 1894.. Serial No- 529,703. (No model.)

To aZZ whom, it may concern.-

Be it known that I, EDWARD P. HOLDEN, a citizen of the United States, residing at Chicago, county of Cook, State of Illinois, have invented a certain new and useful Improvement in Machines for Operating on Sheet- Metal Vessels; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention has for its object the production of a cairseaming machine which shall be adapted to operate upon cylindrical cans (whether with straight sides or with tapered sides) to form either the head in the body of the can, to flange the end of the can-body, to engage the head and body of the can together, or to crimp the flange of the head onto the body.

It consists, essentially, in revolving the can against the forming-flange, the latter being shaped to form the desired result.

The invention consists in a combination of devices and appliances hereinafter more particularly described and claimed.

In the drawings, Figure 1 is a vertical section of a machine embodying my invention. Figs. 2, 3, 4, 5, and 6 are details showing the diiferent forms of formingflanges. Fig. 7 is a horizontal section. Fig. 8 is a view of the under side of a portion of the machine, showing the means for revolving the spools. Fig. 9 is a view of the under side of a portion showing the adjustability of the pins, being a section on the line 9 9 of Fig. 1. Fig. 10 is a vertical section of a variation showing the preferred form of mechanism for holding the vessel onto its support. Fig. 11 is a plan View of a portion of the same. Figs. 12 to 20, inclusive, show the construction of the cans and in connection with Figs. 2 to 6, inclusive, illustrate some of the various results that may be accomplished on the machine.

In carrying out the invention A represents a suitable framework by which the operative mechanism is supported. This framework is preferably circular in form. B is a shaft revolving in the boxings B 1-3 and preferably located in a vertical position.

0 is a pinion or gear keyed to the shaft and meshing with a pinion O on the driving-shaft C the latter being driven from any suitable source of power.

Keyed to the shaft B is a revolving wheel or disk D. At regular intervals on the peripheral edge of this disk D is a vertical pin E, made adjustable on the disk by the set screw 6. Revolving on this pin is a spool F, provided on its lower end with a pinion f, which meshes with a stationary rack-bar j on the frame. (Shown in detail in Fig. 8.) This spool F is provided with a projecting flange f which forms a support for the lower end of the can-body when placed thereon. It will now be observed that when the disk D is revolved the spools F and the cans placed thereon are carried in a circular direction around the machine, and by virtue of the rack-barf and pinionf the spools and cans are revolved.

On the frame of the machine adjacent to the path of the revolvingcan are one or more operating-flanges G II. The shape in crossseotion of these flanges depends entirely on the work to be done. For instance, if it is desired to flange the upper end of the can, as shown at j, Fig. 13, and at the same time pro vide the can with a bead 7", as shown in the same figure, the flanges G H would be shaped as shown in Figs. 2 and 6that is, the flange G would in its upper inside corner have a recess g. The upper end of the spool F would be provided with a projecting flange f corresponding with the recess or groove gin the flange G. The flange H would be provided with a recess h, while the spool would be provided with a correspondingly-shaped projection f As will be seen,the spool has a smaller diameter than the can, and the can will therefore readily slip over the flange f and rest upon the flange f As the disk D revolves the can and spool F will be revolved by the pinion f and rack-bar f and the can, rolling against the flanges G H, as shown in Figs. 1 and 7, will be bent to the desired shape-that is, with the flangej and bead j. In case it is desired to form a flange on the can, as shown at 7 Fig. 14, and a bead, as shown at j Fig. 14, the flanges G II and spool F would be altered accordingly. So, also, if it is desired to unite the seams of the head and body,

as shown in Figs. 15 and 16 at j j a flange G would be provided with a groove, as shown at g, Fig. 3; or if it is desired to first turn the head-flange under the body-flange, as in Fig. 16, and then turn it down, as shown at Figs. 17 and 18, the flange 9 could be the necessary shape in cross-section to first turn the head-flange 7' to the position shown in Fig. 16. Then the cross-section of the flange G could be altered to turn the flange to the position shown at 7' Fig. 17, and then to the position shown atj Fig. 18, orj Fig. 19, so that by starting the can in at one end of the flange in the shape shown in Fig. 15 when it reached the other end of the flange Git would be the shape shown in Figs. 1.8 or 19. So, also, either cans with parallel sides or cans with tapered sides can be acted upon, necessitating only the change of spools on the disk D and the adjustment of the various parts.

To hold the cans down to their work, either an arm or projection K may be provided, as in Fig. 1, or the machine might be constructed as shown in Fig. 10, (and I prefer this latter form,) in which the vertical shaft B is provided with a fitting or collar M, and to this is pivoted radial arms N. Each of these arms is provided on its outer end with a fitting O, carrying a stem 0, on the lower end of which is a disk 0 of somewhat larger diameter than the diameter of the can to be operated upon. The outer end of each arm is also provided with an antifriction-roller N. P is a stationary cam-track, on which the roller N travels. Now, as will be seen, when the shaft 13 revolves these arms these arms, following the shape of the track P, are elevated sufficiently so that the can can be slipped onto the spool, as shown at Q, Fig. 10, and then as the disk carrying the cans revolves the same shaft carries the arms N around until the cam-track has depressed the arm to the position shown on the other side of Fig. 10, and the disk 0 bears upon the end of the can and holds the latter toits work.

The particular advantage in this lastdescribed construction lies in the fact that the disk 0 may be given any desired elevation or depression by simply changing the cam-track, and therefore the space which must be taken up when the can is shortened by beading, as shown in Fig. 10, could be compensated for very easily and the disk 0 always be kept against the end of the can to hold the latter in'place.

It will thus be seen that by simply a change in the flanges G H and in the spoolFany desired work may be done upon either a straightsided or tapered can and upon any-sized can, since the flanges are all adjustable as well as the plate K and the pin E on which the spool F is located.

It is obvious that in this machine, as in other machines of this class where the operation is eifected by a motion of one part with respect to another, the pin carrying the cans might be stationary and the operating-flanges be movable instead of the operating-flanges being stationary and the pins movable about a common center, and I would contemplate by my invention any such obvious change.
