Specification of Letters Patent.

' Patented Dec. 26, 1916.

Application filed A ril 20, isle. Serial no. cases.

' To all whom it may concern:

Be it known that l, FRANK A. Sn'rMANs, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Razors, of which the following is a specification.

My invention relates to improvements in razors, and has for its object the production of a device of this character which will be of improved construction, and eficient in use.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understoodby reference to the accompanying drawing forming a part ofthis specification, and in which,

Figure 1 is a partially sectional front elevation of a razor embodying the invention, Fig. 2 is a partially sectional rear elevation of the device, Fig. 3 is a substantially central section of the device, Fig. 4 is a top plan view thereof, and Fig. 5 is an enlarged section taken on line w-a: of Fig. 1.

The preferred form of construction, as

illustrated inthe drawing, comprises an elongated comparatively flat hollow body 1 adapted, in the employment of the razor, to constitute a handle.- Rotatably mounted in the rear wall of the body 1, at the upper end thereof, is a stud 2, to which is fixed a pinion 3. The front end of the stud 1s squared for engagement with an opening of corresponding form which is provided centrally in a circular blade 4 which is adapted to be mounted upon said stud. The connection between said stud and blade serves to lock the latter to said stud so that upon rotation of the stud, said blade will also be rotated. Said blade is held in operative position upon said stud by the upper end portion 5 of the front wall of the body 1, said portion 5 being hjngedly mounted, as at 6. Spring keepers 7 secured to the rear wall of the razor body are adapted to engage over the lateral edges of the wall member 5 to lock the same in operative position. The construction is such, as will be seen, that upon release of the wall member 5 and forward rocking of the same, the blade 4:

will be free for removal from the stud 2 for sharpening or replacement, as will be readily understoo Carried by the wall member 5 is a guard 8 of arcuate form adapted to coiiperate with the upper exteriorly projecting portion of the blade 4:, as will be readily understood. The guard 8 is secured in position by means of a screw 9 which passes through an elongated slot provided in said guard in order to permit of adjustment of the latter. in the operation of the razor, the blade 4: is rotated, such rotation being eflected by means of a hand operable wheel 10 rotatably mounted in the body 1 with opposite sides projecting exteriorly through slots formed in the lateral walls of said body, said exteriorly projecting portions being adapted for engagement by the thumb or fingers, as will be readily of wheel 10 is knurled to facilitate rotation of the same. Said wheel is operatively connected with the blade 4 by means of a train of multiplying gears 11 interposed between the wheel 10 and the pinion 3, the arrangement being such, that when said wheel is rotated at a comparatively slow rate of speed, the blade will be rotated at a much higher rate of speed.

In order to prevent the entrance of lather or other foreign matter into the body 1 during operation of the razor, strips 12 of rubber or other suitable material are provided at the upper end of said body secured to the front and rear walls thereof, which engage with the opposite sides of the cutting edge of the blade at the points of entrance into the razor body. Said cleaning members 12, engaging with the opposite sides of the lade, serve to wipe oil any foreign matter from the blade, and thus to prevent entrance of the same into the body of the razor, as will be readily understood.

While I have illustrated and described the preferred form of construction for carrying my' invention into'efiect, this is capable of variation and modification without departing from the spirit of the invention. I,

therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come-within the scope of the appended. claims.

understood; The periphery Having described my invention what I claim as new and desire to secure by Letters Patent is:

1. A razor comprising a hollow comparatively flat body; a stud rotatably mounted in said body on one wall of said body at one end thereof; a circular blade mounted on said stud, the opposite wall of said body being hingedly mounted; and means for normally holding said last mentioned wall in operative position, substantially as described.

2. A razor comprising a hollow comparatively fiat body; a stud rotatably mounted in said body on one wall of said body at one end thereof; a circular blade mounted on said stud, the opposite wall of said body being hingedly mounted and adapted, when in operative position, to hold said blade in position on said stud; and means for normally holding said last mentioned wall in operative position, substantially as described.

3. A razor comprising a hollow comparatively fiat body; a stud rotatably mounted in said body on one wall of said. body at one end thereof; a circular blade mounted on said stud, the opposite wall of said body being hingedly mounted; and keepers engaging with the lateral edges of said last mentioned wall for normally locking the same in blade to prevent the entrance of foreign 4 matter into said body; and means in said body for rotating said blade, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
