FREDERICK KAMPFE, OF BROOKLYN, NEW YORK.

RAZOR- SPECIFIOATION forming part of Letters Patent No. 788,835, dated May .2, 1905.

Application filed April 26, 1904. Serial No. 204,954. i

To aZZ whmn it may concern:

Be it known that I, FREDERICK KAMPFE, a citizen of the United States, residing in the borough of Brooklyn, county of Kings, city and State of New York, have invented certain new and useful Improvements in Razors, of which the following is a specification.

My invention relates to razors, and especially to that class where the blade is detachable from the handle and shank.

In the accompanying drawings, Figure 1 is a perspective view of a blade. Fig. 2 is a side view, partially in section and partially in elevation, of a handle, shank, and bladeholder with the blade in place. Fig. 3 is a back view of the construction shown in Fig. 2, and Fig. 4 a cross-section taken on the line 4 4 of Figs. 2 and 3.

Similar reference-letters designate corresponding parts.

Referring now to the drawings which illustrate the preferred form of my invention, A designates a blade detachable from the bladeholder B, which is preferably rigidly secured to and substantially integral with the shank C, which shank may either be extended to form a handle or may be pivotally connected to a handle D, as shown.

In the back or heel of the blade A is formed a continuous groove a. Preferably this groove will be formed in the back of the blade in the early stages of manufacture thereof, as it can then be used to great advantage in the operations of grinding, polishing, honing, &c.

Preferably, too, the blade will be magnetized, in which event this groove increases the efficiency of the blade as a magnet, makes it easier to magnetize the blade, and conserves the magnetism to a greater extent.

When the blade is made detachable from the bladeholder, as shown in the accompanying drawings, this longitudinal groove has another function-namely, that of coacting with suitable projections arranged on the inside of the blade-holder to hold the blade firmly in position therein. For example, in the construction illustrated in the accompanying drawings the metal forming the back or heel l) of the blade-holder B is indented or bent inward to form one or more projections As shown, a number of such rojections are formed by the indented meta being slitted or having the portions at 6 cut away, thus leaving a number of projections b, which coact with the longitudinal groove (1 in the heel of the blade to hold the same firm.

The sides I) of the blade-holder are preferably turned up to bear against the sides of the blade A, which further tends to hold the blade rigid.

The slits 6 give additional resilienc to the blade-holder, and the fact that t iey are formed in the indented portion of the metal prevents the possibility of their edges coming into contact with any surface, such as that of a strop, and this does away with the possibility of scratchin such a surface.

The sides 12 of the b ade-holder will preferably be cut away at the outer extremities, as shown in dotted lines in Fig. 2, which leaves the back of the blade-holder with its projection or rib extending slightly, so as to form a guide for the inner end of the blade as the same is placed in the holder.

Additional lugs or retaining devices may be provided for the inner end of the blade by forming rojections b at the inner end of the blade-ho der. In this case the portions of the metal of the blade-holder will preferably be cut away, as shown at If, for the purpose of giving greater resiliency to the spring-lugs b.

The blade instead of having a rounded back or heel will preferably be cut square, so that the blade will stand on its back, which is a great convenience, especially in the process of washing and wiping, as it does away with the possibility of the blade adhering to the surface upon which it is rested and makes is much easier to handle the same.

What I claim as new is- 1. A razor-blade provided with a continuous longitudinal groove arranged in the back thereof, a bladeholder, and one or more projections arranged within said bladeholder and adapted to coact with the longitudinal groove in. said blade.

2. A razor-blade provided with a continuous longitudinal groove arranged in the back thereof, a blade -holder having the metal of its back portion indented to form a an indented groove in its back, the bottom projection adapted to coact with the contink wall of the groove having portions removed uous groove in the blade. l therefrom to form slits.

3. A razor-blade provided with a contin- In witness whereof I have hereunto signed 15 s 5 uous longitudinal groove. arranged in the my name in the presence of two subscribing back thereof, a blade holder having the l witnesses.

metal of its back portion indented to form a projection adapted to coact with the continuous groove in the blade, said projection be- 10 ing provided with one or more slits.
