SAFETY-RAZOR.

To all whom it may concern:

Be it known that I. O'r'ro KAMPFE, a citizen of the United States, residing in the borough of Brooklyn, in the county of Kings, city and State of New York, have invented an Improvementin Safety-Razors, of which the following is a s 'iecilieation.

My invention is designed as an improvement upon the safety razors shown and described in applications for Letters Patent filed by me, the one under date of October 1906, Serial #331152, and the other under date of July 20, 1907, Serial #381,798, with the object of freely introducing a thin flexible blade into the curved holder of a safety razor and removing the same therc from in a normally flat condition and so rcmoving all liability of cutting the fingers in handling the blade.

In carrying out my invention I provide the body member with openings or bayonet slots which are as deep as is required for the extreme movement of the guard-comb between its full open position with the thin normally [lat blade inserted freely in position and its extreme position under pressure with the flexible blade bent or flexed and ready for use. The construction of the safety razor holder is substantially the same as described in my before-named applica tions.

In the drawing. Figure 1 is a partial central section and partial elevation representing the device of my improvement. Fig. 2 is a rear view of the safety razor and Fig. 3 is a. front clevatioi'i with the guardcomb moved out; in which position the normally flat blade is readily removed or inserted in the holder.

The body member a. as will appear from the drawing is of elongated proportions. It is curved as shown in Fig. 1 in cross section and slightly arched. The upper edge of the body member is provided with overturned edges 2 3 and 4, the edges 2 coming at the sides and the edges 3 and t at the back. These are overturned from the upper edge of the body member so as to form a l'ramc adapted to overlap the-back and thc opposite ends or three sides of the guardcomb c and a thin normally flat blade 17. 'lhcse over-turned, edges are comparatively narrow and the respective .ends are prcl'erably rounded so as not to present any blunt or Specification of Letters Patent.

opposing point to interfere with the handling of the implement.

A part a of the body member is perforated so as to receive the upper reduced end of the tubular handle l) and a washer (L2 pretc ably comes over the perforated end a around the reduced end of the handle which riveted in position to firmly connect the body member at the perforated part and the washer to the tubular handle. The lower end ot the tubular handle as constructed is int'eriorly threaded at b. I

0 represents the guard comb longitudinally curved and transversely flat and cor.- t'ormingyto the curved upper edge and the over-turned edges 3 1 ot' the body member. The guard comb is provided with teeth at its for ard edge and with lugs (3 at its I back edge; the lugs (3 being hook-shaped.

[n the back and at the upper edge of the body member I provide apertures in the form of bayonet slots 5 at their upper parts wide enough to receive the lugs 6 of the guard comb and of a width in their lower parts to corrcs 'iond with the width of the lugs back of the hook ends, consequently the guard comb when its lugs are connected at the openings 5 is free tO'lllOYO down the body member to the depth of the slots 01' openings 6 represents a rod passing through the tubular handle and having formed therewith at its lower end the exteriorly threaded cylinder c and the knurled head 0"; the cylinder 0 screwing into the .interiorly threaded end I) of the tubular handle, the rotation of which parts advances the rod 0 or withdraws the same, and I preler as shown in Fig. 1 to provide the guard comb at about the center with an appreciable recess 7 Fig. 1 to receive the upper free rounded end of the rod 1:.

Fig. 1 shows the e'uard comb and the thin normally llat razor blade in a position of use with the blade under tension and in which position the guard comb is held with torce against the under side of the blade and the blade clamped in the body member be- Ilcath the edges 2 fl and 4; the lugs (5 on the back of the guard comb comin g into the upper parts of the slots 5 as shown in Fig. 2.

Fig. 3 in front elevation shows the position ol the parts with the rod c withdrawn or low r d to an extent which pcrmits of the return of the thin razor blade to its normally flat condition. To attain this position the guard comb is moved down gradually by the force or power of the blade attempting automatically to return to a flat condition with the release of pressure, until the lugs 6 come to the lower portions of the slots 5 and the razor blade r'ully returns to its normally I over-turned edges 2 3 and 4, gradually bending or flexing the razor blade until the parts are brought into arelation of forcible contact with the blade clamped as in Figs. 1 and 2, and in which the parts are ready for use.

I claim as my invention:

1. In a safety razor, the combination with a thin normally flat removable and resilient blade, of a body member adapted to receive ,and having edges to'extend over and engage all edges except the cutting edge of the blade, a longitudinally curved guard comb coming 'against'the under or opposite side of the blade to flex the same and said guard comb adapted for a uniform falling and rising movement equally away from all edges upon its release, providing for the ready insertion of the thin remov'able blade in its normally fiat condition said body member being provided with spaced apart vvertically disposed slots of greater length than the extent of movement necessarily required 'for the guard comb and projecting members of the guard comb. passing through such slots and movable therein and ednstructed for engagement therewithto prevent the accidental separation of thel gua comb from the body, and means foi applyin tension to move the guard comband-qblade,bodily outward against the salim 'edges'of the body member and flex the blade.

2. In a safety razor, a longitudinally curved guard comb hav ing hook-shaped lugs, a body member receiving the comb and having curved engaging surfaces, andhaving bayonet slots which in depth are placed at right angles to the plane of the lugs and receive said lugs, a thin normally flat removable resilient blade placed freely between said guard-comb and body member in its normally flat condition and means for moving the comb and blade bodily and so applying tension to bend and flex the blade and clamp the same ready for use between said parts, the release ofwhich clamping means permits the resilient blade to straighten or r'cturnto its normally flat condition and in so doing move the guard comb.
