Hugh Watson, of Grand Island, Nebraska, assignor of one-half to Jesse Clemens, of Grand Island, Nebraska. Safety-Guard for Razors.
No. 903,347. Specification of Letters Patent. Patented Nov. 10, 1908.
Application filed February 20, 1908. Serial No. 416,937

To all whom it may concern:

Be it known that I, Hugh Watson, a citizen of the United States, residing at Grand Island, in the county of Hall and State of Nebraska, have invented a new and useful Safety-Guard for Razors, of which the following is a specification.

This invention relates to safety guards for razors, and has for its object to provide an improved safety guard by means of which its teeth will be accommodated to permit of proper use of the razor in its position when used in shaving. This object is carried out by the particular construction of the safety guard hereinafter set forth, in which the teeth are set at a slant.

The invention consists in a safety guard for razors constructed as hereinafter set forth and claimed.

In the accompanying drawings:—Figure 1 is a view in elevation and transverse section of a safety guard with a razor blade secured thereto mounted on a handle, the guard being constructed in accordance with this invention. Fig. 2 is a plan view looking at the under side of the guard, the handle detached. Fig. 3 is a modification of the guard. Fig. 4 is a detail view of a portion of the guard showing the shape and position of the teeth.

The guard consists of the body portion 1, which is provided at its longitudinal edges with the rows of teeth, 3 and 4. The said teeth of the said rows are obliquely disposed in relation to the longitudinal edges of the said guard 1. In the form of the invention, as illustrated in Fig. 2 of the drawing, the teeth 3 and 4 are inclined in the same general direction, and when this form of guard is used it is the intention that the razor may be used with one hand only. The said teeth 3 and 4 are formed with the tapering or converging sides 5, and the outer edge portions of the said teeth gradually diminish in transverse thickness, as indicated at 6 in Fig. 2 of the drawing. The said teeth 3 and 4 are located upon the beveled surfaces 7, provided at the edges of the said guard-plate, and, by reason of the fact that said teeth are so positioned, and have the peculiar configuration described, the area between the teeth toward the middle of the plate 1, is gradually diminished; thus the lather and beard which is removed from the face of one using the razor is gradually pushed from between the teeth as it approaches the middle of the guard-plate 1. Thus it will be seen that a free passage or discharge of the said matter or material is afforded.

The form of the guard-plate as indicated in Fig. 3 of the drawing is similar in construction to that shown in Fig. 2, with the exception that the teeth 12, of the set at the opposite side of the said plate are disposed in opposite directions. With this form of guard-plate, one may use the razor with either the right or the left hand.

In both forms of the invention as shown and described the razor-blade 10, is held in position against the guard-plate 1, by a backing plate 9, which is mounted upon a rod or stub 10, which enters the handle 11.

What is claimed is:—

A safety guard for razors, consisting of a plate having beveled edges and teeth spaced from each other, and being located upon the beveled surfaces of the edges of the plate, and being disposed obliquely with relation to the beveled edges.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.

Hugh Watson.
