Sept. 15, 1931. F. RASSIER RAZOR BLADE HOLDER Filed Feb. 7, 1951 INVENTOR FRANK Afls IER BY TOR/NM Patented Sept. 15, 1931 UNITED STATES FRANK RASSIER, OF MINNEAPOLIS, MINNESOTA RAZOR BLADE HOLDER Application filed. February 7, 1931.

This invention relates to razor sharpening equipment, and the primary object is to provide a novel, efficient, and practical design of blade holder which is adapted to firmly hold a safety razor blade so that it can properly be stropped upon an ordinary hone or strop to sharpen its edge. Further and more specific objects will be disclosed in the course of the following specification, reference be 1 ing had to the accompanying drawings, in

which:

Fig. 1 is a perspective elevation of my improved razor blade holder, showing a razor blade as secured therein by the locking plate in closed position.

Fig. 2 is a view similar to Fig. 1, but showing the locking plate as in partly open position.

Fig. 3 is a sectional detail view on the line :12 8-3 in Fig. 2.

Fig. 4 is a perspective detail view similar to the left end portion of Fig. 2, but showing the holder as adapted to receive a different type of blade.

Referring to the drawings more particularly and by reference characters, A designates the handle of the tool, from one end of which integrally extends a plate section B. To the outer end of the plate B is pivotally so secured, as at 5. a second plate C which is so arranged that it will swing in close parallel position with respect to the plate B, leaving only a comparatively thin slot 6 between the plates. In this slot is releasably held the blade to be sharpened. Anchor lugs 7, of a thickness equal to that of the blade. project into the slot 6 from the inner face of the plate B with which they are also preferably integral. These lugs, as shown in Fig. 2 engage notches in the ends of the razor blade, while the design shown in Fig. shows lugs which engage intermediate perforations in the blade. In similar manner the shape and position of the lugs may be arranged in still other 45 ways to accommodate still other makes or Serial No. 514,194.

types of blades, and in some instances it may be found necessary to employ means other than lugs to insure proper retention of the blade in the holder. When the plate G is closed, as in Figs. 1 and 3, it firmly locks the 50: blade in the holder so that the latter may be manipulated back and forth over a hone or strop to sharpen the blade. During the stropping process the holder is of course rocked over its back edge, i. e., the edge opposite of that from which the blade extends and consequently there will be no tendency for the plate 0 to open accidentally and thus release the razor blade. To insure proper firmness and rigidity of the plate C, however, I provide an inclined groove 8 in an enlarged portion 9 of the member AB, to receive the inclined inner end edge 10 of the plate. The enlargement 9 is also provided with a notch 11 to receive a lug 12 at the inner end of the plate 0, thus providing a positive interlock, and also a convenient projection to be engaged by the operators finger to open the device.

It is understood that suitable modifications may be made in the structure as disclosed, provided such modifications come within the spirit and scope of the appended claim. Having now therefore fully illustrated and described my invention, what I claim to be new and desire to protect by Letters Patent 1s:

A razor blade holder comprising a main plate member terminating at one end in a handle and having an enlargement at said end, said plate member having a recess therein to receive a razor blade and projecting lugs to engage the blade and hold it in place with one edge only projecting beyond one edge of the plate, a second plate member pivotally secured at one end to the outer end of the main plate member for locking the blade with respect to said lugs and recess, the inner end edge of said second plate member being angularly formed, said enlargement having an angular groove for slidably receiving and securing the said angular inner end edge of the second plate member, and a lug projecting from the inner end of the second plate member to facilitate removal of the same from the groove, said enlargement having a notch adjacent to the groove for receiving said lug of the secondary plate.

Signed at Minneapolis, Minnesota, this 5th day of February, 1931.

FRANK RASSIER.
