' PRESS I Filed April 22, 1936 ATTORNEYS WITNESS l? Q Auiermn INVEINTOR Patented Mar. 14, 1939 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to presses and more particularly to presses for destroying cans especially for use by automobile service and filling stations or other establishments having need for such devices, and has for the primary object the provision of a simple, durable and inexpensive device actuated by air or fluid pressure whereby cans and like containers after being emptied may be mashed or mutilated to prevent their 10 reuse.

With these and other objects in view, this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and 15 claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a perspective view illustrating a can 20 destroying device constructed in accordance with my invention.

Figure 2 is a sectional view taken on the line 2 2 of Figure 1.

Figure 3 is a top plan view, partly in section, illustrating the device.

Referring in detail to the drawing, the numeral I indicates a rectangular base or anvil having secured thereto vertically arranged and spaced uprights 2 for supporting at the upper end there- 30 of an end plate 3 of a cylinder 4. The other end of the cylinder is closed by an end plate 5 secured to the end plate 3 by tie bolts 6. The end plate 3 is perforated, to provide exhaust openings 1, and also has an opening 8 through 5 which operates a plunger rod 9 carrying at one end a piston l operating in the cylinder 4 and the other end has secured thereto a plunger head ll slidably supported by the uprights 2 and operating in conjunction with the anvil l to mash 40 or mutilate cans and like containers to prevent further use thereof. The plunger head II is of substantially rectangular formation and has secured thereto coil springs l2 which are supported by brackets l3 secured to the end plate of the cylinder. The springs l2 act to urge the plunger head upwardly and also to position the piston in its uppermost position within the cylinder.

A fitting I4 is secured to the end plate 5 and has connected thereto a valve l5. The valve !5 is connected to an air pressure or fluid pressure source (not shown) by a pipe Hi. The valve [5 when in one position will admit the pressure to the cylinder for acting on the piston III to drive 5 the plunger head downwardly in the direction of the base or anvil l. Another position of the valve I5 closes the pressure to the cylinder and vents the latter to the atmosphere so that the springs I2 may act to return the piston and 10 plunger head to their uppermost position.

A device of the character described is efilcient in operation and may be readily moved from one place to another and is easily connectible to an air or fluid pressure system.

Having described the invention, I claim:

A press for destroying cans, comprising a substantially rectangular base providing an anvil for receiving a can, uprights secured to and rising from the corners of the base, a cylinder including an end plate providing a lower head therefor and secured to the upper ends of the uprights, an end plate providing an upper head for the cylinder, tie bolts between the plates for securing the upper head to its cylinder, a piston in the cylinder, a plunger rod secured to the piston and slidably mounted through the lower head, said lower head having exhaust openings therein, a Substantially rectangular plunger head secured to the outer end of the plunger rod and having openings in the corners thereof to receive the uprights for slidable movement on the latter to cooperate with the anvil to crush a can, brackets secured to the upper head and extending in depending relation from diametrically opposite sides thereof, coil springs having their end convolutions secured to the brackets and plunger head respectively for holding and urging the latter upwardly in its normal position, a fitting threaded on the upper head and adapted to be 40 in communication with a source of fluid under pressure for introducing said fluid within the cylinder to act upon the piston for disposing the plunger head in operative position, and valve means mounted on the fitting for controlling the fluid to and from the cylinder.
