' March-10, 1925- J. ROOS CAN OPENER File March 17, 1924 WITNESS Patented Mar. 10, 1925.

UNITED STATES JOHN RODS, OF BEAVERTON, OREGON.

CAN OPENER.

Application filed March 17, 1924. Serial No. 693,709.

To all whom it concern:

Be it known that I, JOHN Roos, a subject of the Republic of Switzerland, residing at Beaverton, in the county of Washington and State of Oregon, have invented a new and useful Can Opener, of which the following is a specification.

My invention relates to improvements in can openers in which a bracket is attached to a wall plate and in which spurs are slidably mounted in the bracket to be pressed into a can.

The objects of my invention are to produce a can opener which can be screwed against the wall and which therefore is readily available when wanted; which is not likely to be misplaced; which does not occupy any room on the table where the room is mostly needed for more important purposes; which opens cans very quickly and with a minimum of effort; and which is sanitary in so far as the same spurs which open the can may serve as closing plugs whereby flies, dirt or dust are prevented from contaminating the containers of the can.

Other objects and advantages are to be found in the construction and arrangement of parts as will be described in the specifications, and particularly pointed out in the appended claims.

I attain these objects with the mechanism illustrated in the accompanying drawing, in which- Fig. 1 is a plan view of the entire mechanism.

Fig. 2 is a side elevation of Fig. 1.

Similar numerals refer to similar parts throughout the several views.

This invention is especially intended for tin cans filled with milk or some other fluid of which only small quantities are needed at a time.

The wall plate 1 is provided with screw holes 2 in order to be fastened to any suitable vertical surface. Attached to the wall plates is a strap 3, whose laterally extending ears 4 are held to the wall plate 1 by means of the screws 5. The upper and lower ends of the strap 3 are bent away from the wall plate 1 and at right angles thereto; said upper end which may be called lug 6 proceeding for a short distance only, while the lower end or lug 7 after proceeding for a short distance in the same width as the body of the strap 3, widens out into a circular baseplate .3 Somewhat larger diameter than the can 9 (indicated in dotted lines in Fig. 2) in order to leave room for the upwardly extendlng projections 10 which serve to center the can 9 properly. A strut 11 from the wall- In operation the arm 13 is turned to one side; a can 9 is placed on the base plate 8 properly centered by the projections 10; the arm 13 with the spurs 14 is then lifted to the proper height against the tension of the spring 17, and carried back across the top of the can 9. After the spurs 14 have been placed in the proper position, a slight blow with the hand on the disk 16 will produce the desired perforation in the top of the can. This done, the spurs are withdrawn by lifting the arm 13, and turning the latter aside permits the removal of the can.

To close the can, the spurs 14 are reinserted into the previously made apertures, in which case said spurs function as plugs, with the rubber washers 15 assisting materially in producing an airtight closure.

Having thus described my invention, it will be seen that my objects have been accomplished and, though I have shown the preferred form of construction, I reserve to myself the right to make minor changes, providing I do not contravene the spirit and principle of my invention.

I claim:

1. In a can opener, the combination ofa wall plate, a strap secured to the wall plate, lugs projecting from the top and bottom of said strap and at right angles to the wall plate, a horizontal base plate forming an extension of said lower lug, and two spurs adapted to be guided by said lugs, said spurs pointing down vertically toward the base plate, the distance from one spur to the other being smaller than the diameter of the base plate.

2. In a can opener, the combination of a wall plate, a strap secured to the wall plate, lugs projecting from the top and bottom of said strap, a base plate having a point in the edge attached to said bottom lug, a strut extending from a point in the opposite edge of the base plate to thewall plate, and two spurs slidably mounted in said lugs, said spurs having a vertical and horizontal: move ment relative to the base plate. v

V 3. In a can opener, the combination of vertical strap, lugs projecting horizontally from the top and bottomof said strap, a rod slidably and rotatably mounted in both lugs, an arm projecting horizontally from the rod arm centrally to the spurs, and a horizontal base plate attached to said bottom lug, the

edge of said base plate being provided with upwardly extending projections on both sides of said bottom lug.

Signedby me at Portland, Oregon, this 20 12th day of March, 1924. H p
