RICHARD WAGNER, OF GHEMNITZ, GERMANY.

MACHINE FOR CLOSING THE SEAMS OF CANS.

SJ EECIFICATI ON forming part of Letters Patent No. 241,457, dated May 10, 1881.

Application filed January 10, 1881. (No model.) Patented in England March 9, 1880, in Germany June 26, 1879, in France January 28, 1880, in Italy March 31, 1880, and in Austria April 17, 1880.

To all whom it may concern:

Be it known that I, RICHARD WAGNER, of Ghemnitz, in the Empire of Germany, have invented certain new and useful Improvements mechanism of a novel character, hereinafter particularlydescribed, for holding and adjusting said wheel or-roller, whereby provision is afforded for conveniently adjusting the wheel or roller to suit cans of different diameters, and for moving it to and from cans of uniform diameter to operate upon them. I also employ, in connection with the above-named rotary clamping devices or disks and adjustable wheel or roller, a vertically-adjustable knifeedged disk adaptedto be adjusted upward and inward by suitable mechanism to turn the edge of the cover of thecan upward while the seam is pressed downward and inward by an inclined surface upon the horizontal adjustable wheel or roller. The head or cover of the can is bent so as to form an in verted-U-shaped flange or rim which receives the outwardlyflared end of the body, and the seaming or closing is done by successive applications of the wheel or roller acting in conjunction with the knife-edged disk.

It also consists in certain novel features of construction and combinations of parts, to be hereinafter described.

The accompanying drawings represent only such parts of my machine as are necessary to explain its construction and operation.

Figure 1 represents a partially sectional end view of my machine, showing the first operation of closing the can. Fig. 2 represents a side elevation thereof. Fig. 3 represents a plan thereof. Figs. 4 and 5 are detail views,

illustrating the position of the wheel or roller and knife-edged disk relatively to the seam at successive operations in the closing of the can; and Figs. 6 and 7 are similar views in which the knife-edged disk is not shown.

Similar letters of reference designate corresponding parts in all the figures.

the head or cover thereof, which, before being placed in'this machine, is furnished with an inverted-U shaped rim, which receives the outwardly-flared lip a of the body of the can, as shown clearly in Fig. 1. i

B B designate disks which are brought to bear, the one, B, upon the bottom, and the other, B, upon'the top of the can, to clamp the latter securely between them. The upper disk, B, is here shown suspended from the frame 0 of the machine, while the lower one, B, is shown as adapted to be moved vertically by means of a hand-wheel, D, actuating a screw-threaded spindle, D, which constitutes a step for the spindle b of the said disk, so that a can may be quickly secured and released. Rotary motion maybe imparted to the disks B B, and through them to the can, by any suitable mechanism.

In the present instance this is effected by a crank, E, which transmits its motion through bevel-gears E E.

F designates a seaming wheel or roller adapted to rotate freely upon a vertical spindle, c. In the present example of my invention the saidwheel or roller is supported in a holder or frame, F, which is provided with journals (1 (1, supported in suitable hearings in a frame, G, hinged by a pintle or pin, G, to the main frame 0 of the machine. As here represented, the upward-projecting journal d of theframe F is supported in a hollow screw, H, having a thread ofquick pitch, and adapted to be turned by a handle,H,while thelowerjoi1rnal,d,is supported by a setscrew, 6?, which may be raised or lowered to raise or lower the wheel or roller F relatively to the seam of the can, the screw H being turned upward to permit the raising .said frame or holder, which may be effected through a handle or arm, 0, will cause the wheel or roller to approach or recede from the can which is to be operated upon.

A designates the body of the can, and A I designates a screw extending from the free end of the frame G, and projecting between lugs f upon the main frame 0. The said screw is furnished with nuts 9 g, by which the frame may be drawn inward,so as to bring the wheel or roller F against the seam of the can. This construction provides for adjusting the wheel or roller into position to conveniently act upon cans of different sizes, while the eccentricity of the journals of the wheel or roller holder, or frame to the spindle of the wheel or roller, provides for a quick adjustment of the wheel or roller to act upon the cans of a uniform size.

To the handle or came is connected a spring, h, for swinging or turning the wheel or roller holder or frame F to remove the wheel or roller from the seam of a can; and i designates a chain or connection connected to the arm or handle 6 and passing over a pulley,j, downward to atreadle or lever. (Not here shown.) By actuating the treadle or lever the wheel or roller is brought to bear upon the seam.

Any convenient motive power maybe employed for operating the machine to rotate the can, or it maybe operated by hand.

For acting in conjunction with the wheel or disk F, I employ a knife-edged disk, 70, which is pivoted to any suitable support, 1, which is provided with any means (not here shown) for raising and lowering the disk, and at the same time move it slightly toward or away from the side of the can-body. The operation of this disk will be clearly described hereinafter.

In the operation of my machine the wheel or roller Fis first brought into the position shown in Fig. 1, and being pressed against the rotating can is rotated by friction and turns the downwardly-projecting edge of the rim of the can-cover A inward under the flaring lip a of the can-body. The wheel or roller is next adjusted to the position shown in Fig. 4, and the knife-edged disk having been adjusted so as to bring its edge under the seam, the wheel or roller is pressed inward, and by the inclined surface at of the said wheel or roller the seam is turned down to the position shown in Fig. 5, at an angle of forty-five degrees (more or less) to the head of the can. The disk is beinglowered out of the way, the wheel or roller is adjusted so as to bring a groove, 11, in its periphery opposite the seam, as shown in Fig. 6,

and the lower edge of the seam is turned inward. The wheelorrollerbeing nextadjusted so as to bring a cylindrical portion of its periphery 0 against the seam, as shown in Fig. 7, the seam is closed down tightly against and parallel with the side of the can-body, and is completed, thus making a tight and smooth joint or seam without solder. To make thejoint perfectly air-tight I may interpose a thin film of chemically-pure vegetable paper throughout the seam before closing.

What I claim as my invention, and desire to secure by Letters Patent, is-

l. The combination ofthe holding and clamping disks B B, the wheel or roller F, the frame or holder F, provided with journals (1 d, eccentric to the axis of said wheel or roller, the hinged frame G, containing bearings for said journals, the screw I, and lugsff, forminga bearing for said screw I, whereby provision is afforded for adjusting the wheel or roller to suit cans of different diameters, and for moving it to and from the can to operate upon'it, substantially as specified.

2. The combination ofthe holding andclamping disks B B, the wheel or roller F, the frame or holder F, provided with journals d d, the hollow screw H, forming a bearin g for the journal d, and the set-screw (1 whereby provision is afforded for adj ustingthe wheel or roller'vertically, substantially as specified.

3. The combination of the can holding and clamping disks B B, the wheel or roller F at the side of said disks, adapted to be adjusted vertically and moved horizontally toward and from the disks, and the knife-edged disk 'k arranged to be adjusted by mechanism vertically and toward and from a can, substantially as and for the purpose specified.

4.. The combination of theholding and clam ping disks B B, the wheel or roller F, the frame F, carrying the same, andsupported uponjournals eccentric to the center of the wheel or roller, the sprin g h, connection i, and pulley j, all arranged substantially as and for the purpose specified.

RICHARD WAGNER.
