MOSES L. IlAl/VKS, OF NEW YORK, N. Y.
CAN-OPENER.
SPECIFICATION forming part of Letters Patent No. 706,823, dated August 12, 1902. Application filedMarch 18, 1902. Serial No. 98,801. (No inodel.)
T0 (tZZ whom, it may concern.-
Be it known that I, MOSES L. HAWKS, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a new and useful Improvement in Can-Openers, of which the following is a specification.
The principal object of my invention is to provide simple and inexpensive means whereby the knife is secured to the handle or frame without the use of screws or rivets or other parts for the purpose,'thus reducing the cost of manufacture as compared with other can The handle or frame A is provided with a centering-spur at one end and also a longitudinal slot ct, extending to a point near the end,
and a short transverse slot 0. for the purpose hereinafter described.
The knife 13, which may be blanked out from sheet metal suitable for the purpose, is substantially of the form shown at Fig. 4 of the drawings, one end of which is pointed and sharpened to a cutting edge. It is then bent as shown at Fig. 5 of the drawings. Preferably the knife is slightly curved in at the center, so that it will bear against the frame, and thus retain its position as adjusted by means of the spring tension, the notches at the sides of the knife engaging the inner edges of the frame. The knife is then secured to the frame by first passing the cutting-point edgewise through the slot 0. from the front side of the frame, then turning around until the blunt or rounded end of the knife-piece will pass through the transverse slot at. It is then bent down flat upon the opposite or rear side of the frame, overlapping the inner edges of the frame, as shown at Fig. 2 of the drawings. The knife may then be adjusted by sliding along the slot at to any desired position without becoming detached from the frame.
In use the spur at the end of the frame is inserted through the center of the can in the usual manner, the knife is adjusted to regulate the size of the opening wanted, the cutting-point is then forced down through the tin, and the can opened by rotating the knife around the center, cutting out the tin in a circular form, all of which will be readily com prehended and easily and. quickly aocom plished.
Having described my invention, what I claim as new, and desire to secure by Letters Patent, is- 7 p A can-opener of the character described, comprising-a handle or frame provided with a centering-spur at one end, a longitudinal slot, and short transverse slots near the end, with an elongated sliding plate having its end bent downward, one end of which is pointed and sharpened forming the knife, the other end being bent backward upon the under side of the frame thus securing the plate and knife to the frameas shown and described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
