RAZOR BLADE HOLDER Edward Olszewski, Detroit, Mich.

Application July 24, 1943, Serial No. 496,259 2 Claims. (01. 51-218) My holder is of the kind that will accommodate razor blades of the wafer, double edge type. The purpose of my invention is to provide a device in which a blade may be held securely and firmly while being sharpened by having its cutting edges rubbed against a flat, slightly abrasive surface such as glass, honing stone and the like.

Another purpose of my invention is to provide a holder in which the blade may be placed easily, quickly and safely and from which it may be as easily, quickly and safely removed.

I shall now describe my invention with reference to the accompanying drawing in which,

Fig. 1 is a perspective view of my holder with the blade holding elements turned down;

Fig. 2 is a side elevation of one of main component parts of my holder, said part being shown somewhat enlarged for better illustration;

Fig. 3 is a side elevation of another main component part of my holder, also enlarged;

Fig. 4 is a perspective view of my holder slightly modified, with the blade holding elements turned upwardly;

Fig. 5 is a top elevation of my holder with a blade in position for sharpening;

Fig. 6 is a side view of a modified locking element, being a part of my holder.

Similar numerals refer to similar parts throughout the several views.

Generally speaking, the holder consists of a handle it! and a transverse member H for the support of a blade, and may be made of metal, plastic or some other suitable material. As shown in the drawing it is composed of two main parts [3 and I4, said parts being clamped together by means of a screw l5 passing through hole It in each of the two parts. As each of said parts is depressed on what is its inner surface, a slot I! is formed automatically when said parts l3 and I 4 are affixed to each other.

The transverse member ll includes a base 30 and a rectangular bed 3|, the latter being narrower than the base and narrower than the conventional two-edged razor blade. The purpose of this construction is to have the edges of the blade extend beyond the sides of the bed as shown in Fig, 5.

Mounted on the depressed surface of part i 4 are two members It? and 26, being substantially circular in shape and provided with intermeshingo teeth 2|. As the teeth are restricted to a part of their respective circumferences, the rotary motion of members l9 and 20 of which they are capable, is limited. Extending tangentially from the rim of each said member, but in opposite directions,

are holding fingers l2, which are normally disposed parallel to the longitudinal axis of the bed and close above the opening of slot H.

Member 20 is provided with a substantially radial lever 22 having a shoulder 22a normally disposed below the surface of bed H3. The lever serves to control fingers I2. When, as shown in Fig. 3, the lever is moved in the direction of the bed, it causes fingers l2 to swing upwardly in a converging arcuate motion, while shoulder 22a enters slot [1, as shown in Fig. 3. When the lever is brought down, the shoulder recedes from the slot, while fingers l2 revert to their normal position.

As a means of locking the shoulder and fingers against movement, I have devised a bolt 24, bearing against a compression spring 21 within a recess 25 in member 13. A retaining plate is indicated by a numeral 26 and retaining pins by numerals 28. When the lever is brought down, the bolt is forced in by a transverse flange 23 on lever 22, but comes back immediately into the path of the flange on its return.

Another locking device is shown in Fig. 6. This consists of a sleeve 33 ending in a bolt 34 and sliding on a horizontal flange 35 of lever 35. The bolt may be shifted manually into a recess 31 in the side of my holder 38. Numeral 39 indicates a blade holding finger.

I have discovered that the blades may be sharpened quicker when the side edges of bed l8, instead of being level are wavy or corrugated. I am therefore showing a bed with such corrugations in Fig. 4.

I shall now describe the operation of my holder: In order to place a blade on bed N3, the lever 22 is moved upwardly to have fingers l2 swing from a horizontal position, in an arc towards each other. A conventional blade having a central longitudinal aperture is placed on bed so that the fingers project through said aperture. The lever is then moved downwardly, causing the fingers to swing back to their initial position and to clamp down the end portions of the blade, as shown in Fig. 5.

It is assumed that the lever has been brought downwardly far enough to be caught by the movable bolt 24, which holds the lever in place. While the blade is thus clamped down to bed 18 by fingers l2, it may be sharpened by being rubbed against a suitable fiat surface as already explained herein.

When it is desired to remove the blade from the holder, the lever is pushed upwardly, past the yieldingly projecting bolt. The shoulder 2212 on lever 22 will abut the blade helping to push it off the bed, as shown in dotted lines in Fig. 3.

It is obvious that some changes in the construction of my holder are possible although such changes may be within the sphere of my inventive concept. What I, therefore, wish to claim is as follows:

1. A holder for razor blades having a central longitudinal aperture, comprising a handle, a cross member thereon, having an inwardly arched bed to support a blade, said bed having a centrally located longitudinal slot designed to be in register with the aperture in the blade, two geared wheels in said slot at right angle to the bed and in mesh with each other, a tangentially disposed clamping finger extending from each wheel in a direction opposite to that of the other, lever means to actuate said fingers by means of said wheels to clamp the end portions of the blade from inside its central aperture.

2. A holder for razor blades having a central longitudinal aperture, comprising an inwardly arched, substantially rectangular bed for a blade, said bed having a centrally located longitudinal slot designed to be in register with the aperture in the blade, two flat members pivotally mounted within the slot, each having a plurality of teeth in mesh with the teeth of the other, a clamping finger on each member, the fingers extending in opposite directions and being normally disposed parallel to the surface of the bed, a lever projecting from one of said members and out of the slot to impart an oppositely rotary motion to said members to cause the fingers to clamp the end portions of the blade from inside its central aperture.
