RAZOR BLADE HOLDER Filed Aug. 29, 1934 Patented Apr. 9, 1935 4' UNITED STATES PATENT" OFFICE;

RAZOR-BLADE HOLDER Harry M. Dahl, Sn, Yoakum, Tex. Application August 29, 1934, Serial No. 741,976

3 Claims.

My invention relates to an improved holder for razor blades and has for its object to provide a holder which is adapted to hold various types of safety razor blades in a manner to permit stropping of the blades.

A further object of the invention is to provide a holder having a pair of jaws movable relative to one another, adapted to receive a blade therebetween and a clamping bar for locking the blade in the jaws to prevent accidental displacement of the blade while stropping the same.

Another object of the invention is to provide a device of the above-mentioned character which is simple and durable in construction, reliable and eificient in use and inexpensive to manufacture.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawing, forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Fig. l is a top plan view of the holder showing a double edge razorblade secured therein,

Fig. 2 is a bottom plan view of the same,

Fig. 3 is a side elevation view of the same with the clamping bar in a raised position, and,

Fig. 4 is a top plan view of the holder showing a single edge razor blade secured therein.

In the drawing, wherein for the purpose of illustration, I have shown apreferred embodiment of my invention, the numerals 5 and 6 denote a pair of jaws constructed from elongated metal strips disposed in superimposed. relation and attached to one end of the jaws is a handle I. The jaws adjacent the handle are fixedly secured together by rivet 8 and the free ends of the jaws are freely movable relative to one another so that a razor blade 9 may be inserted therebetween.

The jaws are relatively narrow so that when the blade is positioned between the jaws the cutting edges of the blade will-project beyond the side edges of the jaws. are bifurcated, as at l0 and I l, to receive the head l2 of the clamping bar l3 which is adapted to lie on top of the jaw 5 when in locking position. The head i2 is off-set from the bar 13 and the connecting portion l4 between the bar and head is reduced to engage in the bifurcations l0 and l I of the jaws, whereby the head I2 engages the underside of the jaw 6, securing one end of the clamping bar and jaws together. The opposite end of the clamping bar I3'is provided with a longitudinal slot 15, adapted to be engaged by the pin it extending upwardly from the jaw 5 and The free ends of both the jaws.

a sleeve II slidably mounted on the jaws is movable over the end of the clamping bar securely locking the bar against displacement. The pin HS when engaged in the slot l5 limits the longitudinal movement of the locking bar, soas to 5 prevent the head I2 from becoming dis-engaged and the sleeve ll holds the bar l3 and jaws together so the pin It will not become dis-engaged from the slot l5. When the sleeve I1 is moved from engagement with the clamping bar it is supported by the raised portion E8 on the jaw 5 on a plane with the clamping bar for ready engagement therewith. j

In use,'various types. of razor blades may be held by the holder for stropping. The improved type of double edge blade having the central longitudinal slot is secured in the holder by first inserting the head l2 of the clamping bar l3 through the slot of the blade, then inserting the blade between the jaws 5 and B and moving it longitudinally of the .jaws until the connecting portion l4 between the head l2 and bar l3 enL- y gages in the bifurcations l0 and H of the jaws, after which the sleeve I1 is moved into engagement with the inner end of the clamping bar l3 securely locking it in its clamped position. Single edge blades and double edge blades of the old type are secured in the holder by first inserting the blade between the jaws and then engaging the head l2 of the clamping bar 13 with the bi ffurcations l0 and H, after which the sleeve ii is moved into engagement with the free end of the clamping bar. While the holder is primarily adapted to hold razor blades for stropping it is apparent that it may also be used for holding razor blades in various positions for useas a scraper, cutting seams and other purposes for which razor blades are now used. I

It is to be understood that the form of my invention herewith shown and described is to be 40 taken as a preferred example of the same and that certain changes in the shape, size and arrangement of the parts may be made without departing from the spirit of the invention or the scope of the subjoined claims. 5

Having thus described my invention, I claim:-

1. A razor blade holder comprising a pair of superimposed jaws movable relative to one another and adapted to hold a blade therebetween, the free ends of said jaws being bifurcated, a clamping bar having a head at one end adapted to engage in the bifurcations at the free ends of said jaws and means for securing the opposite end of said clamping bar to said jaws.

2. A razor blade holder comprising a pair of 55 superimposed jaws movable relative to one another and adapted to hold a blade therebetween, the free ends of said jaws, being bifurcated, a clamping bar extending longitudinally of said jaws having an off-set head at one end adapted to engage in the bifurcations at the free ends of said jaws, and a sleeve slidably mounted on said jawsmovable .to engage over the end of said clamping bar.

3. A razor blade holder'comprising apair of relatively: narrow elongated jaws fixedly secured together at one end and having their free ends movable relative to one another adapted to hold opposite a blade therebetween, the free ends of said jaws having bifurcations therein, a clamping bar extending'longitudinally of saidjaws and adapted to rest on top of one of thejaws, said bar having an off-set head at one end adapted toengage in the bifurcations of said jaws, a pin extending upwardly from one of said jaws for engagement with a slot in theopposite end of said clamping bar, and a sleeve slidably mounted on said 'jawsmovabl e to engage over the end of said 'clamping'bar "-to lock 5 in. clamping position.
