REUBEN sIDEMAN,oF sAN FRANCISCO, CALIFORNIA.

RAZOR-BLADE SHARPENER.

Application filed September 24, 1924. Serial No. 739,626.

To all whom t may concern:

Be it known that I, REUBEN SIDEMAN, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented a new and useful Razor-Blade `Sharpener',

.of which the following is a specification.y

Y This invention aims to provide novel means whereby the blade of a safety razor may be held during'the sharpening of the blade, the construction being vsuch that 'the blade, although securely held for sharpening, may be released readily when the sharpening operation has been concluded.l y

In `the accompanying drawings z- Figure 1 shows in top plan, a device constructed in accordance with the invention, vparts broken away; Figure 2 is an elevation wherein parts are broken away. Figure 3 is a cross section on the line 3 3 of vFigure 1. In carrying out the invention, as disclosed in Figures 1 and 2, there is provided a hold- 'er including a loop-shaped or enlarged body 1, from which project resilient arms 2, 3.

AOne arm is marked by the numeral 18, and the other arm by the numeral 19. The v blade yappears at and is located between the arms 18 and 19, the arm 18 having studs 21, passing through the blade 20, and received in openings 22 in the arm 19.: l

The numeral 23 marks a U-shaped vyoke vcomprising a base 24, and fingers 25 disposed at right angles to the base, the fingers terminating in eyes 26 receiving trunnions 27 on a bell crank lever 28, the bell crank lever comprising a handle 29 and a foot 31. The base 24 of the yoke 23, extends across ture.

the outer surface of the arm 18, the lingers 25 of the yoke being received in oppositely disposed seats 32 fashioned in the edges of the arm 18, the seats 82 being small enough lso that the yoke 23 cannot shift longitudinally 1 of the device.A The fingers 25 of the yoke 23 also pass! through notches 33 that are formed in thearm 19. The foot 31 of the bell crankk lever 28 has some resiliency, and,

when the handle 29 of thebell crank lever is pushed down against the arm 18, the arms 18 and 19 will'belpressed together at their free ends, to grip the blade 2O.l The notches 33 in the arm 19 are large enough, measured longitudinally of the arm 19, so that the arm 19 will not bind on the fingers 25 of the yoke 23, as the arm 19 moves to and from vclosed position with respect to the arm 18.

Having thus described theinvention, what is claimed is In a device for holding razor blades,` 'a clamp comprising arms, a yoke extended about the arms, and a lever fulcrumed on the yokeand engaging one arm, saidarm vhaving notches in its opposite edges `which 'are large enough to permit vrelative movement vbetween the arms, when the lever is 1 disengaged from said arm, the other arm ybeing provided in its edges with seats receivfing the yoke and small "enough to prevent the yoke lfrom shifting longitudinally of the device. v p

In testimony that I claim the foregoing` as my own, I have :aEUBEN sIDEMAN.

hereto affixed my signa
