RAZOR-BLADE HOLDER.

Application filed May 22,

My invention has for its object to provide an extremely simple and highly efficient razor blade holder, and to this end it consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In the accompanying drawings, which illustrate theinvention, like characters in die-ate like parts throughout the several is views Referring to the drawings:

Fig. l is a perspective view of the invention with a razor blade applied thereto; Fig. 2; is a side elevation of the invention with one of the springs released and the razor blade removed;

Fig. 3 is a, view artly in side elevation partly in *long1tudinal central section. showing a razor blade mounted in the opposite spring tromthat shown in Fig. 1; V

Fig. i is a fragmentary detail view, on an enlarged scale. with some parts sectioned,

the razor ressed; and lulg". 5 is a transverse 5-5 of Fig. 4. a i

The improved holder comprises a pair of scar springs 6 and 7 and a slidable sleevelilze handle 8. The sear springs 6 and are turned toward each other in longitudinal adjustment and have one member :ef each spring integrally formed. Both sear springs 8 and 7 are formed from a single halt-round spring rod which. when the members of said springs are compressed, are round in cross section. The handle 8 is mounted on the springsfi and 7 for longitudinal sliding movement from one spring to the other for holding the members thereof compressed or section on the line -for telescopioal movement onto the free members of both springs forsimultaneously holding their loose members compressed.

lit will be noted that the free member of the spring 6 is somewhat shorter than the free member of the spring 7 and that the space between its members is less than that between the members of the spring: 7. The spring 6 is adapted to hold a relatively short and thin razor blade w, as shown in Fig. l, and the spring 7 is adapted to hold'a relativelv long and thick razor blade 51 as shown in Fig. 3. The outer ends of. the springs 6 and 7 are upset at 9 to aii'ord stops to prevent the handle 8 from being removed from the springs.

In applying a razor blade to the holder ment with the strop by turning the henblade holderwith both springs 7 is hiahlv important in produoin 1926. Serial No. 110,924.

ber thereof and the handle 8 telescoped over the inner end of said free member to hold" the razor blade clamped between the members of the spring. as shown in Figs. 1 and The tension of the free members of the springs 6 andlis such as to securely hold the handle 8 against endwise sliding move ment on theflsprines or rotation thereon.

With the razor blade held by the improved holder the same may be stropped as with an ordinary straight razor and the blade reversed each time it is brought into en between the fingers and thumb oi the openator. The diameters of the springs 6 and 7. when compressed. are such that when strepping a razor blade the respective spring will lie on the strop and hold the edge of the blade in a manner to produce bevel on the edge of the razor b ich run.

cutting edge.

'VVhat l claim is:

1; A blade holder comprising a lonsitw diually extended member having clamping arms at its opposite ends projecting inward ly toward each other. and a single sleeve mounted upon and about said member and freelv movable in opposite directions thereon to slide over and clamp both or either of said arms to said member.

2. A razor blade holder comprising" two sear springs turned toward each other longitudinal alignment and having two of these membersinteg'rally formed, a sleevelilre member mounted on said spring'an movable from one searspring to the other to hold the tree members thereof compressed while the tree member of the other spring is released. said sleeve-like member being arranged. when holding the free member oi? one spring: compressed, to he slid over the inner end ot the free member of the other spring); to hold the same-compressed to clamp a razor blade between the member of the respective spring. The structure defined in 01mm 2 in which the outer ends of the SPI'lIlgS are m as;

upset to )re'vent the removal of the sleevelike mem er from the springs.

4-. The structure defined in claim 2 in which the members of one spring, When compressed, are spaced differently from the members of the other spring when compressed.

5. The structure defined in claim 2 in which the free member of one spring is longer than the free member of the other 10 bers of each spring are compressed, are 15 round in cross section.

In testimony whereof I afiix my signature.
