A further object of my invention is to providev longitudinal strengthening means for the blades fashioned from the same material as the blades so that the possibility of the blade breaking at its edges is minimized.

Ano-ther object of my invention is to provide a blade and a razor therefor which has means for placing the blade in a position to be easily washed and wiped safely so that cleaning of the blade will be facilitated thus providing a sanitary blade for subsequent use.

My blades may be made of untempered steel formed and then the cutting edges tempered and sharpened, or such blades may be made of tempered steel and then the flange members and the central portion of the blade can be annealed. The process of making the blade can readily be determined upon for the type of the razor in which the blade is to be used and the result desired.

For a fuller understanding of the nature and objects of my invention reference is had to the following detailed description in connection with the accompanying drawings, in which:

Referring to Figs. 1 to 4, inclusive, of the drawings, numeral -25 represents a double-edged razor blade having a pair of parallel longitudinal springs or ange members 26 cut from the central portion o-f the blade leaving end portion 2l, 2l and creating longitudinal channels 29. rihe springs 2G are bent first parallel to the body of the blade as shown at 3B and then at an oblique angle to the blade as shown at 3l.

Referring to Figs. 5 to 7, inclusive, blade 32 is the same as blade 25 except that the parallel longitudinal springs 33 are bent inwardly from the same material at an oblique angle to the blade creating longitudinal channels Sli.

Referring to Figs. 8 to l0, inclusive, blade 35 is the same as blade 25 and blade 32 except that the parallel longitudinal springs 36 are bent inwardly at an oblique angle to blade and the ends 31 of the springs 35 are bent downwardly toward the blade creating longitudinal channels 38.

Referring to the razor shown in Figs. 11 to 17, inclusive, numeral 39 is a guard for a doubleedged blade, comprising a central Ilat portion lll] and guard portions ill. Pivoted at 43 at one end of the guard 39 there is a forked member :i2 to receive the longitudinal springs 26 of blade 25 within the channels 29. Similarly, blades 32 and 35 may be placed upon the forked member 42. A stop -52 extends beyond forked member 42 so that when member i2 is in open position, it will stop at about to the guard 39. Attached to pivot 43, there is also a cap 44 arranged torcover blade 25 and forked member i2 and be Vsnapped into position by latch $5 over one end of guard 39. Within the inside of cap 44 there is attached a block 46 with tapered sides 41 and threaded hole 48 in the central portion thereof. Hollow handle 49 has telescoped within its central portion a screw 50 long enough to engage threaded hole 48 when cap 44 is in closed posi tion. At the opposite end of screw 5U there is a nger knob 5l which is arranged to stop a predetermined distance below the handle 49 when screw 5l] is disengaged from cap 44.

In order to use the razor, latch 45 preferably with the springs facing toward flat portion 49, is snapped open and forked member 42 is moved to its 90 position to the guard 39. Blade 25 is then placed upon the forked member 42 by sliding the forks of member 42 into the channels 29 of the blade s0 that springs 28 will hug member 42. The blade 25 and forked member 42 is then allowed to drop upon guard 39. Cap 44 is then pivoted over` blade 25 and guard 39 causing block 46 to fall within opening 28 of blade 25. Latch 45 is then snapped over the end of guard 39 and knob v5l is turned so that screw 50 engages threaded hole 48 and the razor is then ready for shaving.

It is obvious that various changes and modifications may be made in the different details Of' construction of my blades and razor without departing from the general spirit of my invention, as set forth in the appended claims.

I claim:

1. A double-edged razor blade comprising a pair of parallel longitudinal springs formed from the material of said blade, said springs being bent first parallel to the body of said blade and then at an oblique angle to said blade.

2. A double-edged razor blade comprising a pair of parallel longitudinal springs formed from the-material of said blade, said springs being first bent at an oblique angle to said blade and the ends then bent downwardly toward said blade.

3. A double-edged razor blade comprising a pair of parallel longitudinal springs formed from the material of said blade, said springs beingequally distant from the longitudinal medial line of said blade, said springs being bent first parallel to the body of said blade and then at an oblique angle to said blade.

4. A double-edged razor blade comprising a pair of parallel longitudinal springs formed from the material of said blade creating a pair of longitudinal channels, said springs being bent at an oblique angle to the body of said blade.

5. A double-edged razor blade comprising a pair of parallel longitudinal springs formed from the material of said blade creating a pair of longitudinal channels, said springs being i-lrst bent at an oblique angle to said blade and the ends then bent downwardly toward said blade.

6. A double-edged razor blade comprising a pair of parallel longitudinal springs formed from the material of said blade, said springs being equally distant from the longitudinal medial line of said blade, said springs being first bent at an oblique angle to said blade and the ends then bent downwardly toward said blade.

7. A safety razor, comprising a hollow handle attached to a guard a part of a hinge at one end of said guard, a hingeable fork-shaped bladesupporting member having a part of a hinge at one end, a stop on said blade supporting member, a cap having a part of a hinge at one end, said parts of said hinge held together by a pivot pin, a threadedhole in the center of said cap, a screw thro-ugh said hollow handle for tightening said cap.
