HENRY SCHAAKE, OF SAN FRANCISCO, CALIFORNIA.

CAN-HEADING MACHINE.

SPECIFICATION forming part of Letters Patent No. 548,463, dated October 22, 1895.

Application filed December 18,1898. Serial No. 494,000. (No model.)

To all whom it may concern.-

Be it known that I, HENRY SCHAAKE, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Gan-Heading Machinery; and I do hereby declare the following to be a full, clear, and exact description of said invention, such as will enable others skilled in the art to which it most nearly appertains to make, use, and practice the same.

The present invention is designed for the placing of can-heads inside of can-bodies and may be termed an inside heading machine for can-bodies, it belonging to that class of headers set forth in Letters Patent No. 235,700, granted to George H. Pierce on the 21st day of December, 1880, and the invention relates more especially to the construction of the header and retaining jaws, or what is more commonly known as the molds.

In the Pierce patent, No. 235,700, twooperations are required before the head is applied to the can-body, the first being the flaring outwardly the end of the can-body and the second forcing the end or head into the ex-i panded end, the machine being an intermittent rotating one. This double operation necessarily greatly delays the heading of the can-body and prevents the output of a great number of cans per day.

My invention has for its object to facilitate the heading of cans by increase in the rapidity by which the head is applied, this being accomplished by applying the head in one operation.

This machine is designed more especially as an improvement upon the can-heading machine covered by Letters Patent granted to Chas. B. Kendall on the 21st day of April, 1891,No. 450,624, and like said patent I make employment of oppositely-rotating mechanisms, carrying header and retaining jaws, but with this difierence, that in my machine the head is applied inside, while in Patent No. 450,624 the head is applied outside. By prefence I locate the oppositely-operating mechanisms one above the other, for the reason that less space is occupied by the machine, which is an important consideration in can factories.

The manner of securing the header and retaining jaws to the oppositely-operating mechanisms, of causing the closure or bringing of the jaws together so as to inclose the canbod y, of feeding the can bodies and heads to the jaws, and of forcing the pistons inward so as to insert the flange of the can-heads inside the can-body being the same in construction and operation as the mechanism fully set forth and described in the aforesaid Letters Patent No. 450,624, detail description need not be given in this specification, for no claim is made thereto except in combination with my specific improvement, which relates to the jaws for receiving and so holding the canbody as to permit the flange of the can-head fitting inside thereof.

In order to more fully understand my invention, reference must be had to the accompanying sheets of drawings, wherein- Figure 1 is a vertical sectional view taken on line 00 00, Fig. 2. Fig. 2 is an end elevation showing the trackways for forcing the header and retaining jaws to and from each other in order to cause the closing and opening thereof. Fig. 3 is a detail longitudinal section of a headed can-body; and Fig. 4 is a side elevation of the heading-machine, showing position of the can-body, can-head, and discharge-chutes for the cans.

In the drawings, the letters A A represent two pairs of plates mounted upon shafts B B, which plates are bolted or otherwise secured to a vertical frame A (See Fig. 4:.) Said plates are arranged above each other, as shown in Fig. 1. From the inner face of these plates project the ribs which form circular pathways or tracks 0 G G 0 To the drive-shafts B B, I rigidly fasten the disks D D, which are rotated and carried around with the movement of the drive-shafts, said disks being located between the stationary plates A A. These disks carry around the trucks E E, which are mounted upon axles a a, upon the outer ends of which are secured the rolls 1] h, which travel within the circular trackways G O, and serve to throw the trucks in or out in order to force the header and retaining jaws G G to or from each other. These jaws are mounted upon the shafts gg. In order to facilitate and secure a perfect registering of the header and retaining jaws I provide the rolls e e, which are held in place tion of each will be found fully set forth and described in Letters Patent No. 450,624.

The present machine is provided with feedchutes for the heads and bodies, as will be seen by reference to Fig. 4, wherein J indicates the can-body feed-chute for supplying the bodies to the jaws of the header, J the chutes for supplying the heads or ends thereto, and J the chute for receiving the headed cans as discharged from the machine.

\Vithin the inner face of each jaw I out two semicircular grooves H 11, which when the jaws are brought together form a complete circular space of greater diameter than the diameter of the jaws. The material intermediate these grooves Islightly cut away, so that the diameter of the jaws between the points 1 2 when closed will be greater than from 4 3, or that portion of the jaws which encircle the can-heads, say, for the thickness of asheet of metal.

The can-body I when the jaws are closed will be held within the larger diameter, the ends thereof projecting within the annular grooves and coming flush with the inner face of the smaller diameter containing the canheads I. .W'hen thus held, the can-heads 1' are forced into the can-body as thepistons are moved inward by the action of the horizontal cams.

The object in providingthe annular grooves in the jaws is to permit the ends of the canbody to expand somewhat as the can-heads are forced therein, in order that a tighter joint may be formed.

Having thus described my invention, what I claim as new, and desire to secure protection in by Letters Patent, is-

1. In a machine for applying heads inside of can-bodies, the combination with a clamping device, jaw or mold which receives, clamps and holds the can-body its entire length and which receives and holds the can-heads to be applied inside the can-body, said holding device being made in sections which when brought together entirely surround the heads and body, the inner face of each section being cut away so as to provide a clamping device of two diameters, the larger diameter of which receives the can-body and holds it throughout its entire length while the smaller diameter holds the can-heads, and of devices for automatically forcing the heads into the ends of the can-body.

2. In a machine for applying heads to the inside of can bodies, the combination with a device for receiving and holding the can body and heads, said device having its inner face of two diameters, the smaller diameter of which retains and holds the can heads and the larger the can body, the annular groove into which the ends of the can body extend, and ofa device for automatically forcing the can heads into the can body.

3. In a machine for applying heads to the inside of can bodies, the combination with oppositely operating mechanisms adapted to operate toward each other in a vertical plane, header and retaining jaws or clamps secured to the respective mechanisms and operated therewith, said clamps or jaws having their inner face cut away so that when brought together a holding device of two diameters is provided, the larger of which encircles and holds the can body, the smaller diameter the can heads, and of mechanisms for automatically forcing the heads into the can body.

4. In a machine for automatically assembling can bodies and heads and forcing the heads inside the can bodies, the combination with the can head and can body feed chutes,

a device for receiving and holding the bodies and heads, said device being of two diameters, the larger of which holds and retains the can bodies and the smaller the can heads, a device for forcing the flange of the heads inside the can bodies, and a discharge chute for receiving the headed'cans.

5. In a can heading machine for assembling can bodies and can heads and forcing the flange of the heads within the ends of the can bodies, the combination with the oppositely operating mechanisms, a section of a jaw or mold secured to each mechanism which sections when brought together form a jaw, mold or clamp which entirely surrounds the can body and heads held therein, said jaw, mold or clamp being of two diameters inside, the larger of which retains the can body and the smaller the can heads, a device for forcing the can heads inward so as to place the flange of the can head Within the ends of the can body, and the chutes for supplying the heads and bodies to the machine and a chute for receiving the headed cans as discharged from the machine.

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

HENRY SCHAAKE. Witnesses:
