w.`A. EVERS RAZOR BLADE HOLDER Filed Jan'. 24". isgs- Patented May 13, 1924.

UNITED STATES WILLIAM A. E'VEBS, 0F MARTINSBURG', WEST VIRGINIA.

RAZOR-BLADE HOLD-ER.

Application filed J'anuary'24, 1923. Serial No. 614,672.

T alt whom t may concer/1t.'

Be it known that I, WILLIAM A.l Evans, a citizen of the United States, residing at Martinsburg, in the county of Berkeley and State of lVest Virginia, have invented certain new and useful Improvements in Razor- Blade Holders, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in razor blade holders, and more particularly to a device of 'this character in which razor blades may be secreted and held and from which they may be extended for use in a cutting operation.

An important object of this invention is to provide a device of this character for holding standard types of safety razor blades.

f A still further object of the invention is to provide a device of this-character for simultaneously holding two di'erent types of blades.

It is well known to those'familiar with the art that blades .of the Gillette type are generally made very thin and are easily bent and accordingly are only adapted for use in very light cutting whereas other typesof blades having a single cutting edge are no made relatively stiffer and accordingly are capable of use for heavier work. It is the purpose of this invention to provide a holder by means of which Ione blade of each type may be held.

An additional object of the invention is to provide novel and improved means for holding the blades lin both concealed and extended position and to provide a structure whereby the blades may be easily extended for use.

. These and other objects I attain by the construction and arrangement Shown in the accompanying drawings-wherein for the purpose of illustration is shown a preton ferred embodiment of my invention and wherein like reference characters designate like parts` throughout.

Figure 1 is a perspective of one form of holder; y

'Figure 2 is a perspective of a slightly modified form thereof;

Figure 3 is a section on the line 8*-3 of Figure 1;

Figure 4 is a side elevation of the form shown in Figure 1, the blades being extended; and

Figure 5 is a section on the line 5-5 of Figure 4.

Referring now more particularly tothe drawings, the numeral indicates a casing longitudinallyelongated and substantially rectiform in cross section, being in the form of a relatively wide, narrow oblong. This casing has formed therethrough a longitudinally extending opening 11 which opens through the ends of the casing and which is in communication with a slot 12 opening through a narrow wall of the casing at one end of the casing and extending to and slightly beyond the center thereof. The casing is provided in its side walls with openings 13 and 14 communicating with the slot 11 thereof.

At one end the slot- 11 of the casing is of a width suilicient to accommodate a blade' Gr and a cam 15, the casing being notched at this end to allow operating space for a clamping nut 16 mounted upon the end of a pivot screw 17, the head of vwhich is mounted in the opposite wall of the casing and which extends through the blade G in an opening 18 normally employed for holding the blade in position upon the razor with which it is used and formed adjacent one end of the blade and through the cam 15. Adjacent this end of the casing the opening 11 is enlarged, as indicated at 19, to the thickness of'a second blade E, the end of the enlargement forming a shoulder limiting the movement of the blade E toward that end of the casing in which the pivo-t bolt is mounted. From this point the opening 11 of the casing tapers towards the opposite end 20 of the casing where it is of a thickness equal to the thickness of the blade E and of a slide plate 21 having an operating end 22 which may extend through the wall of the casing either at the opening 14 or throughthe enlargement 12a of the slot 12. Adjacent the end ofthe casing a lug 23 is formed through which extends a threaded aperture adapted for the reception of a thumb screw 24 which may be extended through the wall of the casing at this point for engagement with the plate 21 to lock the plate 21 or plate 21 and blade E against longitudinal movement in the opening 11.

By an inspection of the sectional view shown in Figure 3, and which corresponds toa section taken on a correspondingly numbered line of the construction shown in Figure 1it will be seen that when the slide plate 21 is withdrawn by engagement of the finger with the operating portion 22 thereof to that end of the slot 14 or sloty 12a remote from the end 2O of the casing, the blade` E Will be comparatively free to slide and may bereadily projected from the kend 2O of the casing by engaging the same through the opening v13 in the side wall thereof. With the blade in the desired position, the lslide plate Q1 may be again shiftedtovard the end 2O of the casing and the thumb screw 24 tightened with the rcsult that the blade will be held in the desire-d position. lt will furthermore be obvious that with the slide plate in the position shown in solidi lines in this section, by engaging the blade G through the opening 141-, the same may be rotated about the pivot bolt 17 through the slot 12 to place the same in the position shown in solid lines in Figure The opening 14 preferably communicates with the slot 12 or enlargement 12" thereof so that full and complete access to the bolt (l to swing the same may be had. Since this communication of these openings would expose the edge of the blade G when in the closed position to a certain extent, the sliding plate 21 in the closed position of the knife is so arranged as to cover the opening 14e and accordingly the projecting edge of the blade G to prevent accidental engagement thereof with the clothing'or fingers in handling` the knife. The cam plate 15 is provided with an elongated tail piece 15a which When the cam is swung with the blade to the open position, the blade G extends beyond the end of the casing and reinforces that edge of the blade Gr which it is not intended to use. By tightening the nut 16 the cam and blade may be secured in the extended position for use or in the closed position.

From the foregoing it is believed to be obvious that a holder constructed in accordance with my invention permits the .housing of razor bla-des of different types and assures proper maintenance of the same in either closed or open position. lt will furthermore be obviousthat this construction as hereinbefore set forth is capable of some change and modification without materially departing from the spirit of my invention and .l accordingly do not limit myself to such specific structure except as hereinafter claimed.

I clafimzll. l'n a device of the type described, a casing oblong in cross section and having an opening formed therethrough, a pivot mounted in one end of the casing adapted for extension through an opening formed in a razor blade adjacent one end thereof, a cam plate mounted within the opening upon said pivot and abutting said blade, and a clamping nut on the pivot operable from the exterior of the casing to bind the clamping plate against said blade, said casing having a slot formed in the side wall thereof through which the blade is rotatable to extended or closed position.
