To all whom it may concern:

Be it known that I, Henrie Clauss, a citizen of the United States, residing at Fremont, in the county of Sandusky, State of Ohio, have invented certain new and useful Improvements in Safety-Razors; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to safety razors, and consists in the construction and arrangement of parts hereinafter more fully set forth and claimed.

The objects of the invention are to produce a razor of the character described, of simple and inexpensive construction, wherein the handle and blade holder are formed integral of a single piece of metal; to provide a razor wherein the handle and blade holder are so shaped and so connected as to enable them to be cast or forged out of a single piece; to provide a razor wherein a multiplicity of parts is obviated, and wherein there are no joints or movable members to interfere with the perfect cleaning of the instrument; to produce a razor wherein there are no springs to hold the parts together or hold the blade in place, and wherein a stiff blade or a wafer blade may be used with equal facility; to provide a razor where a single or a double edged blade may be used, and wherein the blade is so held as to maintain it securely in place and yet enable it to be readily removed, and easily inserted, when desired.

The above objects are attained by the structure illustrated in the accompanying drawing, in which:—

Figure 1 is a plan view of one side of a razor involving my invention. Fig. 2 is a plan view of the opposite side to that shown in Fig. 1. Fig. 3 is an enlarged longitudinal section through the blade-holding plate, the screw for holding the blade and adjusting it with respect to the guards, and a portion of the handle. Fig. 4 is a perspective view of that portion of the razor shown in Fig. 3, with the blade removed. Fig. 5 is an enlarged transverse section on line 5—5 of Fig. 1. Fig. 6 is a perspective view of the blade.

Referring to the characters of reference, 1 designates the blade-holding plate which is provided at its opposite edges with the guard teeth 2, forming in effect a comb along the opposite edges of said plate.

Formed integral with the plate 1 and projecting therefrom in axial alinement therewith is a handle 3 for manipulating the razor. At the juncture of the handle and blade is a curved offset 4, and extending diagonally through the handle at said offset is a tapped aperture 5 in which is threaded a screw 6 having a knurled head 7. The inner end of the screw 6 is provided with a conical point 8, which, when the screw is screwed through said aperture, projects onto or sightly overhangs the end of the plate 1 adjacent to the handle. Projecting from the face of the plate at the opposite end thereof, but in alinement with the conical end of the screw, is an undercut lug 9, the inner face of whose over-hanging portion is beveled outwardly, as at 10. The blade 11 which is herein shown and provided with two cutting edges 12, is adapted to lie upon the plate 1 with the edges thereof supported by the guards 2.

For the purpose of securing the blade in position upon the plate 1 and adjusting it centrally thereon so that its cutting edges shall lie properly upon the guards the requisite distance from the ends of the teeth thereof, said blade is provided in its opposite ends with the U-shaped notches 13. These notches are located an equal distance from the cutting edges of the blade and one of them is adapted to engage the lug 9, and the other to be engaged by the conical end 8 of the screw 6. In securing the blade in position, the notch at one end thereof is caused to engage the lug 9 and the screw 6 is turned so as to carry the conical end 8 into the notch at the other end of the plate, whereby as said screw is turned into place, the conical end thereof engages the margin of the notch in that end of the blade and crowds the blade longitudinally to carry the notch at the other end forcibly against the shank of the lug 9, under the inclined, over-hanging portion 10, and at the same time because of the taper of said screw presses the blade forcibly against the plate, whereby said blade not only becomes centered upon the plate, but is at the same time firmly held thereto, as clearly shown in Figs. 2 and 3. To remove the blade, it is only necessary to turn the set screw 6 backwardly until the conical end thereof is withdrawn from engagement with the notch in the blade, when said blade may be lifted from the plate 1.

While I have described and shown the blade having two cutting edges, it is evident that a blade with but one cutting edge may be employed, with equal facility.

By means of this arrangement a comparatively thin blade may be employed, or one of considerable thickness, as may be desired.

It will now be apparent that by means of this arrangement, a safety razor is produced of the utmost simplicity, cheapness, durability and strength, wherein the arrangement is such that all open joints and angles are obviated, enabling the razor to be easily cleaned, thereby rendering it highly sanitary. It will also be apparent that by reason of the means shown of securing the blade to the holder or plate, which is adapted to carry it, a blade may be quickly placed in position and securely held by a simple manipulation of the screw 6, the operation of tightening the blade in place also serving to adjust its edge properly with respect to the guard.

Having thus fully set forth my invention, what I claim as new and desire to secure by Letters Patent, is:—

1. A razor comprising a handle having at one end an integral flat portion forming a blade-holding plate, said plate having a guard at one edge, a fixed blade-engaging member at one end and a movable blade-engaging member at the opposite end, a flat sheet metal blade lying upon said plate, said fixed and movable members engaging the opposite ends of the blade only to removably retain it in-place upon said plate.

2. A razor consisting of a handle having a flattened portion at one end thereof and an offset therein at the termination of said flattened portion, a guard upon said flattened portion, a blade lying upon the flattened portion and guard, means for centering the blade on said flattened portion, and an inclined screw passing through said handle at said off-set therein for engaging the blade to detachably retain it in place.

3. A razor comprising a handle having a flattened portion at one end, a lug at the outer end of the flattened portion, a blade lying upon the flattened portion and having in one end a notch to receive said lug, the opposite end of the blade also having a notch and a tapered screw engaging therein.

4. A safety razor, consisting of a handle having at one end a flattened portion to support a blade, a blade lying upon said flattened portion, an undercut lug at one end of the flattened portion engaging one end of said blade, and a tapered screw passing at an angle through the handle and engaging the opposite end of the blade for forcing it against said lug and clamping it against the face of said flattened portion.

5. A safety razor, consisting of a handle having a flattened portion at one end, a blade adapted to lie upon said flattened portion, a stop to engage one end of the blade, and an inclined screw passing through the handle and engaging the blade at the other end at an angle to its longitudinal axis.

6. A safety razor, comprising a blade-holder having a flat blade-supporting surface with fixed blade-engaging means at one end and movable blade-engaging means at its opposite end, a flat sheet metal blade removably secured in position upon said holder by the means engaging its opposite ends, and a handle extending longitudinally from the end of the blade-holder, substantially as described.

7. A safety razor, comprising the blade-holder having guard teeth at its opposite edges and a handle extending longitudinally from one of its ends, the detachable blade provided with notches in its opposite ends, and fixed engaging means coöperating with the notch in one end of the blade and movable engaging means coöperating with the notch in its opposite end for detachably securing said blade to the blade holder, substantially as described.

In testimony whereof, I sign this specification in the presence of two witnesses.

Henrie Clauss.
