APPUCATION FILED lULY3|191L Patented Apr, 13, 1915.

CHARLES W. JPE'IOSKY, 01E MILWAUKEE, WISCONSIN, ASSIGNOR 'IO BADGER- SAFETY RAZOR COMPANY, OF MILAUKEE, WISCONSIN, A CORPORATION OF WISCONSIN.

Specification of Letters Patent.

Application filed July it, 1911. Serial Ito. 636,620.

To all whoiit it may concern Be it known that I, CHARLES W. Pn'rosnr, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Safety-Razors, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

This invention relates to improvements in safety razors of that type in which separate blades are used on opposite sides of the holder.

It is one of the objects of this invention to provide a complete safety razor comprising only a few parts which are co-related to each other so that the blades may be easily assembled in operative positions in the holder and be detached therefrom, and when assembled the parts will be in the most efficient position for shaving.

A further object of the invention is to provide a safety razor in which the blades may be easily and quickly removed or replaced for cleaning or stropping.

With the above, and other objects in View, the invention consists of the improved safety razor and its parts and combinations as set forth in the claims, and all equivalents thereof.

In the accompanying drawing in which the same reference character indicate the same parts in all of the views Figure 1 is a side view of the complete safety razor; Fig. 2 is a View taken at right angles to Fig. 1, a portion of the handle being in section; Fig. 3 is a vertical sectional view of the safety razor; Fig. 4 is a horizontal sectional view thereof taken on line 4-4: of Fig. 1; Fig. 5 is a transverse sectional view of the holder the section being shown as extending in a line across the plane of the blades; Fig. 6 is a vertical sectional view of the holder taken on line 6-6 of Fig. 3; Fig. 7 is a side view of one of the end plates of the holders;

' Fig. 8 is a side view of a portion of the handle used to hold the blades while stropping; and Fig. 9 is a similar view taken at right angles to Fig. 8.

Referring to the drawing the numeral 12 indicates the holder which is provided with elongated blade recesses 13 formed in the opposite side edges thereof and 14 the end plates covering the opposite ends of the holder and the ends of the recesses. The end ends of the blades so that plates are fastened to the holder by means of small screws 15.

The holder is of cylindrical concavo-convex form in cross section with the recesses extending at an angle toward each other from the opposite side edges 16 of the holder. Blades 17 are adapted to be inserted into the opposite elongated recesses and are provided with end notches 18. These blades are slightly longer than the holder and the .end plates are provided with recesses 19 holder and the blades and the toothed side edges 22 of the guard are of suflicient length toproject a slight distance beyond the cutting edges of the blades to serve as a guard therefor.

The guard is provided with projecting pins 23 which enter pin recesses 24 of the holder and with an aperture 25 through which extends the threaded portion 26 of the handle 27. The threaded portion of the handle is adapted to be screwed into the threaded opening 28 of the holder to secure the holder and the guard and the handle together. As the guard 21 fitting the concave portion of the holder 12 bears against this portion and the blades as shown in Fig. 6 and the threaded portion of the handle may be screwed into the threaded opening l 28 of the holder, the guard being disposed therebetween as shown in Fig. 3, it will be noted that the screwing up of the handle into the holder secures the guard in place and resultantly the blades 17 which bear against the guard will be secured in place by the tightening up of the guard which construction serves to clamp the blades in position.

The outer end portion 29 of the handle is reduced in diameter and slotted longitudinally approximately the entire length of the reduced portion as indicated by the numeral 30 to hold one of the blades in stropping. A thumb nut 31 threaded on the which is engaged by one of the notches 18 a of the blade When the blade is clamped in position between the bifurcated ends of the I handle. A tubular cap 33 extends over the reduced portion of the handle and engages the enlarged portion thereof.

From the foregoing description it will be seen that the safety razor is very simple in construction and the parts may be easily separated for cleaning and replacing the blades and when the blade becomes dull it may be clamped to the handle in a convenient position for stropping.

The position of the blades provide for the most efficient angle in shaving and the blade holding means securely lock the blades in position. v

. What I claim as my invention is:

1. A safety razor, comprising a holder provided with elongated recesses, remov able plates connected to the holder and covering the ends of the recesses, a blade extending into the recess and engaged at each end by the end plates to lock the blade in the recess a guard positioned adjacent to the blade, and a handle relnovably extending through the guard and connected to the holder.

2. A safety razor, comprising a holder provided with an elongated recess open at one side and 'both end edges, a blade extending into the recess and having notched ends which project beyond the recess, end plates removably connected to the holder and covering the ends of the recess and provided with recesses into which the projecting ends of the blade extend to lock said blade in the recess, a guard resting against the holder, and a handle extending through the guard and threaded into the holder.

In testimony whereof, I affix my signature, in presence of two witnesses.

CHARLES W. PETOSKY.
