To all whom it may concern:

Be it known that I, CHARLES H. OoUM- have invented certain new and useful Im-L provements in Razors, of which the following is a specification.

This invention relates to improvements in safety razors.

A main feature of the invention is to proma, (1n this case the guard being located on the. side of the blade oppoments in the specific form of locking means by the guard and handle, by which a less number of parts are used than heretofore, wherea detachable guard has been employed.

This invention also relates to improvements in specific details, of construction and arrangement of parts etc,

Other objects of the invention will here-. inafter appear, as will be shown in the speci fication and claims.

which a locking rod 6, operates. The rod 6,

is reduced as at 7, to form a shoulder 8, at

one point, and from the opposite end of the reduced portion the rod is beveled, as at 9, for a purpose to be described. The movement of the rod is limited in the opening 5, and is provided with a groove or slot 110, in

which fits a pin 11, extending from the bar 3. Intersecting the opening 5, is a vertically disposed opening 12, in bar 3, toreceive a projection or post to cooperate with the rod to effect the locking of the parts.

A substantially V.-shape cross section, of uniform thickness having two extensions 13 and cutting edges 14-14, is sup ported on the angularly disposed faces of the bar 3, and extends slightly beyond the ends of the same, as shown in Fig. 3. The blade will be of suflicient thickness to form a rigid structure to insure of a substantial structure when the parts are assembled and the underside, at the apex forms a recess to receive,

the projection formed at-the apex of the holder. The sides of this blade are arranged at an angle to each other with the terminal edges of said sides projected at an angle to said sides, as seen clearly in Figs. 2 and 4.

:In the apex of the blade is an opening 12 which registers with the opening 12, in the bar 3. Fitting over the blade is a cap member 16, comprising two angul'arly disposed sections 1717, corresponding to the angle of the outer surface of the knife, and connected by a web 18, fitting over the apex of the blade at a point about the center thereof.

The lower ends of the. cap are dropped below the normal angle of the two members and are formed with longitudinal slots 19, through which the edges of the blade pass. By reason of the slots, two connecting rods or guards 20, are provided at the lowerends of the guard, which are normally below the lowers edges of the blade, and the distance between the inside of said rods about equals the distance between the two edges of the blade. Depending from the web 1 8, is a post 19, formed-with a slot 21, at its lower enu. The width. of the lower end of the slot equals the diameter of the reduced portion 7, of the bar 6, while the upper portion of said slot is enlarged, and about equals the'normal diameter of the rod. I

To assemble the 'parts,-the blade is fitted on the bar 3 of the frame 2, then, by reason of the width between the guards 20-20, of the cap 16, thelatter can be dropped down over the blade lo, the post passing into the openings to hold the blade in position on fit of the rod 6, in the enlarged portion of the slot is such as to form a frictional contact. ,To release the connection, the movement of the rod 1s reversed, by endwise pressure thereon in an obvious direction to bring the reduced portion in almeinent with the lower end of the post.

The relationship of the guard with reference to the blade, is such that when one is shaving there can be no liabilityof presenting the Wrong angle to the face which is so cutting into the flesh of prevalent with the safety razors.

The angular disposition of the blades with relation to the guards 20-20, makes it possible to shave with the razor held in the hand in the most natural position without liability of cutting. VVhen the razor is drawn over the face on the line bb, obviously the edges cc, of the guard will serve as a means for preventing the edge of the blade the person using the razor.

By making the blade of V-shape cross section and a proper width blade, I am enabled to produce a rigid sheet steel blade, thus overcoming all the objections to the old "type flexible sheet steel blade. I do not wish this to be confused with any V-shaped sheetsteel bladc, whose two diverging faces are of such .vidth that the blade is flexible.

The razor can be adjusted to suit a coarse or a fine beard by varying the angle of the cutting edge of the blade in relation-to the face. This is accomplishedby holding the handle at an angle to bring the blade to suit any beard.

The invention is extremely simple, and effectivean'd by means of the relationship and shape of the parts the blade may be made stronger than the blades of this type now in use.

By making the opening 12 in the blade elongated it facilitates the placing and re moval -of the blade from the guard, 19. This however is not obligatory asa perfectly round opening can be used if desired.

The blade may be formed as shown in Fig; Ziif desired thus giving it an extra stiffening.

In this form the end edges-0f the sides of the blades, adjacent the apex of said sidesp are connected by bridging strips 12, which effectively stiflens the blade asan entirety.

What I claim is:

forated blade of substantially V shaped cross section ,and having a longitudinal cutting edge, of a handle embodying a holder, a per foration in the holder to cooperate with the perforation in the blade and a cap having a lug adapted to cooperate with both perforations and a cooperating member to detachably secure the blade to the holder.

2. In a razor, a handle comprising a trans-- versely extended holder of substantially V- shaped cross section with rigid end portions, and a clamping or locking device one member of which extends longitudinally under the apex of the holder and parallel thereto,
