CAN-OPENER.

Specification of Letters Patent.

Patented Mar. 9, 1915.

Application filed flctober 3, 1914. Serial No. 86%,913.

To all whom it may concern Be it known that I, JOHN P. WALSH, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Can-0p eners; and I do hereby 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 appertains to make and use the same.

This invention relates to can openers, and one of the principal objects of the invention is to provide a can opener of simple construction which will operate quickly and which will readily cut out the top or head of a square or round can by a single out without rotating the cutters, said cutters being connected to the operating screw by a ball and socket joint, so that the screw will turn without rotating the cutter.

Another object of the invention is to provide a cutter of either round or square form in which the cutting blades are angular in form having an inclined cutting edge and a vertical rear edge, so that when the cutter is forced down into the top of a can, the entire top or a continuous opening will be formed therein permitting the removal of the portion cut by the separate cutting points.

The foregoing and other objects may be attained by means of the construction illus trated in the accompanying drawing, in which,

Figure 1 is a vertical sectional view of a can opener made in accordance with this invention, the threaded plunger or shaft being shown in elevation, Fig. 2 is a detail perspective view of the cutter removed from its shaft or plunger, Fig. 3 is a view of the lower end of the plunger or threaded shaft and showing the ball member of the cutter secured to the socket, and the cutter being broken away at opposite sides of the ball, and Fig. 4 is a top plan view of a cutter of circular form.

Referring to the drawing, the numeral 1 designates a shelf projecting from a wall or suitable support 2 and connected to the shelf 1 is a bracket 3, said bracket having an arm 1 which projects underneath the shelf and is secured thereto by means of suitable bolts 5. The bracket 3 is provided with a horizontal arm 6 at its upper end, said arm being provided with a screw threaded bore 7. Fitted into the threaded bore 7 is a shaft or plunger 8 provided with a cross handle 9 at its upper end. The shaft or plunger 8 at its lower end is provided with a cross head consisting of two separable members 10 and 11 secured together by means of bolts 12 extending through both members and said members are provided with semi spherical sockets 13, so that when they are both brought together, the socket is round to accommodate a ball member 14 formed on the cutter. The cutter comprises the rectangular frame 15 having crossed brace bars 16, and located centrally of the cross bars 16 is the ball 14 which is adapted to be connected to the socket 13 of the plunger or shaft 8. Projecting downward from the rectangular frame 15 are the cutting teeth or blades 17 said blades each having an inclined cutting edge 18 and an unsharpened vertical back edge 19. As shown in Fig. 41 the cutter may be round instead of rectangular as shown in Figs. 1 and 2.

The operation of the invention may be briefly described as follows: A can a is placed upon the shelf 1, and the shaft or -plunger 8 is rotated to bring the points of the cutters or blades in contact with the top of the can, and by further rotation of the shaft 8 the top is cut out of the can and the opposite rotation of the plunger or shaft 8 will carry the cutter out of the way. With this form of cutter, the contents of the can are not disturbed since it is held upright and the top is cut out without rotation of the cutter to disturb the contents of the can. The form of teeth of the cutter insures the removal of the entire piece of metal from the can, said piece conforming to the contour of the cutter frame.

Changes in the details of construction may be resorted to without departing from the spirit and scope of the invention as defined in the claims.

What is claimed is l. A can opener comprising a bracket having a horizontal arm provided with a threaded bore therein, a threaded shaft or plunger mounted in the bore and provided with a handle, said shaft having separable members provided with a ball socket at one end, a cutter comprising a frame having a ball thereon to engage said socket, said frame being provided with projecting cutters or b ades, e h having an inclined cutjoint, whereby the plunger may be moved 10 toward a can ithout rotating-the cutter.
