My invention relates to safety razors and thefiobject of my invention is to provide a razor that embodies four cutting edges formed on a single plate and means; for identifying the respective cutting edges or blades.

A further object is to provide nieans to 1 hold the blades in proper relation to the.

holder. 1 I j .Referring to the drawings which form a part of this specification.

Fig. 1 .is a pers ecti-ve view of a razor 2 construction'embo ying my invention 5' Fi 2 is a sectional view taken onaline' B of smaller diameterthan that of the.

' threaded portion thus providing a shoulder 13 against which the guard plate E is held by a screw D which extends through the central opening E therein. *A similar opening E is formed in the razor plate F so that the screw B may hold all three plates together on the handle. 1

Thetop' plate C and guard plate E are formed in the shape of a rectangular pyramid, the outer edges G-GGG respec-' tively of which are disposed on a common plane. They are, formed by a die and of pressing and, are consequentl adapted-to maintain their shape when finis ed.

The top plate is provided with pins H-H extend through the openings pressed from thin sheet metal and are ren ered stiff and unyielding by the operation.

respectively which pass through holes 1-1- respectively formed inthe razor plate F and guard plate to hold them in proper relative position. I I

The razor plate F isfiexible and is slotted as indicated at JJJJ respectively to permit the blades to bend and conform to the surface of the guard plate as will be readily understood and the razonplate is provided with two additional holes I-I respectively'so that all four out- "edges L-L-L -L respectively maybe brought successively opposite any side of the 123 or 4 thereon brought opposite the opening M in the top plate so that the user may "know which blade is to be used for the next shave, etc.
