SAFETY RAZOR.

Application filed July 81, 1826. Serial No. 126,152.

This invention relates to improvements in safety razors, and has for one of its objects to provide an improved razor of simple and practical construction wherein provision is made for mounting a pair of blades thereon in such manner that a repetition of the shaving operation is obtained with every stroke of the-razor. I

Another object is to provide clamping means for a blade which will cause the same to assume a configuration wherein the transverse curvature of the blade will be gradually increased from one end toward the other.

thereof.

The above and other objects will appear more clearly from the following detail description, when taken in connection with the accompanyin drawings, which illustrate preferred em odiments of the inventive idea.

In the drawings Figure 1 is a side elevation, partly broken away and shown in section, of a razor constructed in accordance with the invention;

Figure 2 is an end elevation;

Figure 3 is a section on the line 33 of Fi re 2;

igure 4 is a section on the line 4-4 of Figure 2;

Figure 5 is a view similar to Figure 2 showing a slightly different form of the invention;

Figure 6 is a fragmentary side elevation, partly broken away and shown in longitudinal section, of the form shown in Figure 5; and Figure 7 is a section on the line 7-7 of Figure 5.

Referring more particularly to Figures 1 to 4 of the accompanying drawings, the numeral 5 indicates the handle of the razor which is provided with a bifurcated end 6, the bifurcation of which receives the extension 7 of a mounting 8. The handle and threaded extension 15 and guide pins 16. In assembling the razor'the blade 10 is first mounted upon the extension 15 and pins 16 in the customary manner following which the guard 12, blade 11 and guard 13 are successively positioned upon said extension 15 and pins 16, so that the blade 10 will be interposed between the guard 12 and clamping plate 14 and the blade 11 between the guards 12 and13. As is customary with razors of this type the guards and clamping plate are curved transversely, but in contra-.

distinction to the usual type, instead of curvplate. With the blades thuscurved the cutso ting edges thereof are so disposed that when the same are engaged with an area to be shaved they will have, in effect, a shearing action designed to facilitate the shaving operation. Also by providing a pair of blades, it will be apparent that with every stroke of the razor the shaving of a given area will be repeated.

The form of theinvention shown in Figures 5 to 7 is precisely the same as that above described with the exception that the guards 12 and 13' andthe clamping plate 14: are curved uniformly throughout their.

lengths so that the edges of the blades 10 and 11 will be parallel with a horizontal plane extending through the blades. This form of the razor may. be especially employed when preparing patients for surgical operations and the double blade arrangement willhave the effect of thoroughly removing the hair.

It is to be noted that although only two blades are shown and described, a larger number may be employed with equal facility by the use of a corresponding number of guards.

What is claimed is:

1. A razor including a guard, and a clamping plate cooperating with said guard to clamp a-blade therebetween, said guard and plate having opposed transversely curved faces with the curvature of said faces being gradually increased from ad'acent ends thereof toward their opposite en s and being adapted to correspondingly" flex said blade. v

2. A razor including a mounting, a pair of guards, and a clamping plate detachably connected to said mounting and adapted to clamp one blade between said pair of guards and another blade between one of the guards and said plate, said guards and plate being curved transversely and the curvatures thereof gradually increasing from one end toward the other.

In testimony whereof I have aflixed my signature.
