Application filed. March 19, 1927. Serial No. 176,789.

I My invention relates to safety razors and relates more particularly to improvements in that type of safety razor which is designed to have used therewith a flexible replaceable 5 steel blade and which is commonly known as the Gillette type of razor.

The Gillette type of safety razor is highly desirable because the blades can be replaced and a sharp blade always had at a small cost. In these days of scant attire for women, they often employ a safety razor for shaving unsightly hair from the arm pits. It has been found dangerous, however, to use the average safety razor, whether the Gillette or other types, because the sharp corners of the blade protrude sufficiently to cut the skin when con.- tacting with a cupped or depressed area, such as the arm pit,

. My invention is particularly useful for shaving arm pits and other depressed orconcave skin areas of the body without fear of injuring the skiri. This invent-ion employs the standard Gillette type of flexible steel blade and consists of a curved top member in which the blade resides and a curved bottom or guard member for,'in connection with the top member, giving the blade the desired curvature. The top member is so designed that it is impossible for the corners or ends of the blade to contactlwith the skin area being shaven. ,A suitable screw handle assembly is, of course, provided.

In the accompanying drawing in which I- have illustrated a preferred embodiment of my invention and in which like reference characters'refer to like'parts,

Figure 1 is a top plan view of my improved razor,

Figure 7 is a sectional view of the razor,. I 50 taken along theline 77 of Figure 3', and

body portion of the top or blade receiving member, which is provided with a screwvtlu-caded shaft 2 and blade positioning studs a The blade receiving member is, in fact, shell-like, being cast from brass or other suitable metal with the shaft 2 and studs 3 integral therewith or it may be pressed out of sheet metal and have the shaft 2 and studs 3 welded or otherwise secured in place. The studs 3 act to position the blade and guard member. Obviously, the studs3 are only desirable elements and are not necessary as shaft 2 will'position the blade and guard member with respect to longitudinal movement and the shoulders 5 of the blade receiving member will position-the blade and guard member with respect to lateral movement. I From each end of-the body portion 1 and integral therewith, extend semi-cup shaped shields or shield portions 4 so that the blade receiving member may be characterized substantial'l as an inverted gondola-like shell. I have shown the shields 4 as being semi-cup shaped so that a curved surface will always contact with all parts of the skin being shaven. It

will be obvious, however, that theseshields4 i I may be made any desired shape, the purpose of them being mainly to form a housing for a the corners of the razor blade and to form a blade receiving member which willcon rm somewhat to the surface wh1ch1t 1s inte ded to shave. -The cup-shaped shields 4 also assist 'in holding the lather that is gathered and accumulated from the shaven skin area by the'blade. By reason of the shape and size. of the shields 4, as shown for instance in 1.

Figures 2 and 4, shoulders 5 are formed which, together with the shields 4, determine the effective cutting length of the blade tobe used with my "razor and also position both the blade and guard member against lateral movement.

welding for-instance, the handle 7. 'From both sides,'preferably, of the body portion 6 extend the guard prongs 8. From the ends The guard member consists ofacurved bodyportion 6 to which may be secured, by

shaft 2 protruding into the handle 7 and.

Figures 6 and 7. The prongs 9 are shortened just sufiiciently to fit snu 1y within the shields 4 thus, together with the latter, forming a complete housing for the corner of the razor blade. The prongs 8 are preferably of such a length that when the razor is assembled the tips of the prongs will be in a line forming a tangent with the outer surface of the shields 4. The guard member is provided witlr two holes through which the studs 3 (if present) may extend when the razor is assembled. The handle 7 is hollow to receive the shaft 2. The inside of the blade receiving member is given the proper curvature to give to the flexible blade, when assembled in the razor, an arcuate curvature as shown particularly in Figure 7. The .upper face of the body portion 6 of the guard member has a similar curvature.

The blades 11 to be used with my improved razor are the standard Gillette type of thin flexible steel which can be obtained upon the market at a very small cost. The body portion 1 of the blade receiving member is shorter than the cutting edge of the blade 11 so that when the blade is positioned in the blade receiving me nber only a portion of the cutting edge of the blade is exposed, namely, that portion-of the cutting edge whichlies between the'inner shoulders 5 formed by shields 4 with the body portion 1. The sharp objectionable corners of the blade 11 must, therefore, reside within and are entirely surrounded by the shields 4, so that when the razor is assembled and used for shaving, the

skin will not be torn or cut by the sharp corners of the blade 11.

It is scarcely necessary to describe the assembling of my improved razor. The blade 11 is positioned in the blade receiving mem her, the studs 3 (if present) and the threaded shaft 2 passing through positioning holes that are provided in the blade. The guard member is then positioned upon' the blade, the

"the studs 3 protruding through positioning holes in the guard member. A cylindrical invternally threaded member is provided for insertion in the" handle to screw onto the shaft 21nd force the guard member against the blade thereby causing it to take the desired curvature for comfortable shaving.

It is, of course, possible to merely reduce the length of the four end prongs of the guard member of the standard Gillette type of safety razor so that it Will' fit into my improved blade receiving member. Thus by providing my improved blade receiving memberwith the standard .Gillette type. of safety razor, the guard member of which-has, been altered as above described, the user can alternatively employ the set for shaving 'said to be adapted to shave any part of the human body without fear of injury thereto.

I claim 1. In a safety razor, a blade receiving member comprising a body portion shorter than the blade it is to receive and semi-cup shaped shields at the ends-of said body portion and integral therewith, and a guard member having a plurality of prongs on either edge thereof, the end prongs being shorter than the others'and being adapted to be housed in the said shields. I

2. In a safety razor, a blade receiving membcicomprising a body portion with shoulders at the four corners thereof and a shaft member protruding from the center of the inner side of said body portion adapted to snugly receive the blade and guard member so as to position the blade and guard member against both longitudinal and lateral movement.

3. A 'blade'receivi-ng member for a safety razor comprising a body portion having semicup shaped'shield portions at each end thereof forming lather receptacles.

4. A blade receiving member for a safety razor comprising a body portion having extended shield portions at each end thereof recessed to receive the ends of-a safety razor blade and semi-cup shaped to form lather re- 'ceptacles. 1 5. A blade receiving member for a safety razor comprising." a curved body portion which is shorter than the blade it is adapted to receive andwhich has extended shield portions at each end thereof recessed to house the ends of a blade received in said member and being received in shield portions which are semi-cup shaped-to'form lather receptacles. In testimony whereof I afiixmy signature. .ALBIN K. PETERSON.
