Raymond H. Wilhelm, of Chicago, Illinois. Safety Razor Application filed August 9, 1921.Serial No. 490,974.

To all whom it may concern:

Be it known that I, Raymond H. Wilhelm, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Safety Razors, of which the following is a specification.

This invention relates to safety razors and an object of this invention is to provide a combined safety razor and flashlight which are arranged so that the rays from the light will project upon the face of the user of the razor so as to prevent the casting of a shadow over the face and permit the shaver to clearly see the portions of his face as they are engaged by the razor enabling him to make a clean shave.

Practically every shaver has experienced difficulty and annoyance at times owing to the improper position of light when shaving often resulting in leaving some of the beard on the face in spots, and it is an object of this invention to combine a battery lamp structure which is embodied in the handle of a safety razor and may be excited during shaving with the razor for clearly illuminating the shaver's face.

Another object of this invention is to provide a razor carrying head which is provided with a pair of light deflecting surfaces projecting at acute angles from the axis of the lamp bulb and towards the cutting edges of the razor blade so as to properly distribute the light from the bulb.

Other objects of the invention will appear in the following detailed description and in the accompanying drawing wherein:

Fig. 1 is an edge elevation of the improved razor.

Fig. 2 is a side elevation of the razor.

Fig. 3 is a fragmentary vertical section through the razor.

Fig. 4 is a top plan of the improved razor head.

Fig. 5 is a plan of the razor blade.

Referring more particularly to the drawing the improved razor comprises a handle 1 which includes a cylinder body shell 2 forming a housing for a battery 3 of the dry cell type. The cylinder shell 2 has a removable cap 4 removably mounted upon one end which engages the annular flange 5 formed upon the lamp socket 6 and clamps the lamp socket securely in position relative to the shell 2. The plug 7 of the lamp structure 8 is threaded into the socket 6 and the central electrode 9 thereof engages the central electrode 10 of the battery 3while the circuit is completed through the body shell 2 by moving the slidable contact 11 into engagement with the disc 12 of conducting material, which has a spring 13 engaging it which spring also engages the battery 3. The disc 12 is insulated from the cap 14 by suitable insulating discs 15 and the cap 14 is threaded upon the shell 2 for maintaining the battery 3 and discs 12 and 15 in proper position.

The cap 4 has the razor carrying head 16 formed thereon, which head is drilled to provide an internal screw threaded bore 17 which receives the shank 18 of the back 19 of the razor structure. The back 19 clamps the blade 20 against the razor head 21 to properly position the blade for shaving and the head 21 is provided with spaced teeth 22 under its edges to provide a safety razor. The razor carrying head 16 is also provided with two cutout portions 23, which form outwardly inclining light deflecting surfaces 24 which radiate from the axis of the bulb 8 outwardly towards the cutting edges of the blade 20 to properly deflect the light rays from the bulb 8 upon the face of the user.

The head 21 of the razor structure is securely clamped in place by the thread of the shank 18 into the razor carrying head 16.

The bulb 8 may be excited at the will of the user, by operation of the sliding contact 11 and as long as the contact is maintained in engagement with the disc 12 the lamp 8 will be excited.

If it is so desired, glass, preferably concave-convex, as shown at 30 may be placed within in the cut-out portions 23 to prevent water from entering the casing or body 1 of the handle structure during the cleaning of the razor. It is to be understood, however, that glass may be dispensed with if desired.

In Fig. 4 of the drawings the top plan of the improved razor head structure 19 is shown, the blade being illustrated in Fig. 5 of the drawing. The blade 31 is provided with a straight edge 32 extending throughout its entire length and with a relatively short straight edge 33, extending parallel to the edge 32 and also extending equal distances in each direction from the transverse center of the blade. The cutting edged portions of the blade 31 outwardly of the ends of the cutting ends are concavely curved as shown at 34, these concave cutting edges being provided to facilitate the shaving of the user's face such as along the jaw bones and about the chin, which portions of the face are rather difficult to properly clean with the ordinary straight cutting edge of a razor. A razor head 19 is constructed in accordance with the shape of the blade 31 and it has the usual form of guarding teeth along all of its edges which lie in proximity to the cutting edges of the blade.

It is, of course, to be understood that the invention may be constructed in various other manners and the parts associated in different relations and, therefore, I do not desire to be limited in any manner except as set forth in the claims hereunto appended.

Having thus described my invention what I claim is:

1. In combination a safety razor head having a threaded shank, illuminating means including a shell and a bulb, a reflector supporting the bulb and having a flange resting upon the end of the shell, a head having a threaded bore for receiving said shank and having cutout portions forming deflecting surfaces converging towards the center of the bulb, a cap secured to the head and adapted to have screw threaded engagement with the shell for binding said flange in position.

2. In combination a safety razor head having a threaded shank, illuminating means including a shell and a bulb, a reflector supporting the bulb and having a flange resting upon the end of the shell, a head having a threaded bore for receiving said shank and having cutout portions forming deflecting surfaces converging towards the center of the bulb, a cap secured to the head and adapted to have screw threaded engagement with the shell for binding said flange in position, and glass covers for said cutout portions.

In testimony whereof I affix my signature.

Raymond H. Wilhelm.
