Hermann Hessenbruch, of Philadelphia, Pennsylvania. Safety-Razor.
SPECIFICATION forming part of Letters Patent No. 554,873, dated February 18, 1896. Application filed November 6, 1895. Serial No. 568,074. (No model.)

To all whom it may concern:

Be it known that I, Hermann Hessenbruch, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Safety-Razors, which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists of a safety-razor having a head adapted to hold the blade and a resilient body, a frame with means for adjusting the cutting-edge relatively to the guard, said head and body being formed integral, possessing advantages as will be hereinafter set forth.

Figure 1 represents a perspective view of a safety-razor embodying my invention. Figs. 2 and 3 represent side elevations thereof at a right angle to each other. Figs. 4 and 5 represent perspective views of different forms of the invention.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings, A designates a body which is U or equilateral shape, having on the limb A′ thereof the longitudinal channeled member B, which forms a head to receive and hold the back of the razor-blade C, said blade extending across the body and having its cutting-edge overlying the guard D, which consists of a roller whose journals are mounted on the ears E, which are attached to a plate F located on the side of the limb G of the body opposite to the head B.

H designates a screw which passes through the limb A′, then through the opposite limb G and an opening in the plate F, and is fitted in the nut J, which is on the outside of said plate F, it being noticed that the body A and head B are formed of a continuous piece of metal, the body especially being of an elastic nature, so that the limbs thereof may be closed or separated by the action of the screw H, it being noticed that when said screw is turned in one direction the limbs may be brought together, whereby the cutting-edge of the blade may be advanced so as to occupy a proper position over the roller D for primarily adjusting the edge of the blade relatively to the roller D, which is the guard for said edge, and for subsequently advancing said edge as it is worn away in use and sharpening. It will also be seen that the roller and the plate F which carries the same may be readily removed for repairs or other purposes.

In Fig. 4 the ears K, which form the bearings for the journals of the guard, are formed of the limb G of the body A.

In Fig. 5 the roller is dispensed with and a lip L is substituted therefor, the same extending longitudinally outside of the limb G and continuous of the outer end thereof, said lip acting as a guard similar to said roller.

It will be seen that the body A is of a most resilient nature, so that it is sensitive to the action of the screw H, and is further more light, strong, simple and inexpensive in its nature.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is—

1. A safety-razor, consisting of a body of U shape, having a channel on the outer end of one of its limbs, a plate having an opening therein, and provided with ears on its sides, a roller journaled in said ears, a headed screw passing through both limbs of said body, and the opening in said plate, an adjusting-nut on said screw and a blade held in said channel, said parts being combined substantially as described.

2. An elastic body of U shape, an adjusting-screw fitted to the opposite limbs thereof, a channeled head on said body receiving the back of the blade, a guard for the edge of said blade opposite to said head, and a plate having ears carrying said guard, said plate being held on the adjacent limb of said body by said adjusting-screw, and said body and head being integral, substantially as described.

3. A safety-razor consisting of the body A of U shape having the channel B at the outer end of one of its limbs, the plate F with the ears E, the roller D journaled in said ears, the blade C held in said channel, and the adjusting-screw H passing through the plate F and both of the limbs of the body, said parts being combined, substantially as described.

4. A safety-razor, having a U-shaped body of elastic metal, a blade held by one of the limbs thereof, a detachable plate having a roller journaled thereon, and an adjusting-screw with a nut, said screw passing through both of the limbs of the body and said plate, said parts being combined, substantially as described.

Hermann Hessenbruch.
