Sept. 6,1932. G. s. MOORE SAFETY RAZOR Filed Deo. 19, 1931 Patented Sept. 6, 19322 UNITED STATES eILEs s.` Moenia,- I` INDIANAPOLIS, INDIANA SAFETYl RAZOR AppIication led. December 19, 1931. Serial No. 582,148..

Ihis Invention relates to safety razors and its object is to provide a device of this character having the advantages both of a safety razor and an ordinary straight razor, and` which will have a long life due to theconstruction of the blade, and one in which new blades may be easily inserted.

A further object is to provide improved razor blades which will be inexpensive and yet effective.

Further general objects will become apparent from the description which follows Referring to the accompanying drawing which is made a part hereof and on which similar reference characters indicate similar parts,

Figure 1 is an end view of my safety razor with all parts assembled,

Figure 2, a section on line 2-2 of Figure 1, Figure 3, a view of the safety razor head reverse from that shown in Figure 1,

Figure 4:, a view similar to Figure 1, but showing a one-piece razor blade,

Figure 5, a perspective view partly in section showing an edge of the razor, and

Figure 6, a detail showing an element for securing the handle to the shank of the razor. In the drawing numeral 10 indicates a head portion having a screw threaded stud 11 which extends through a plate 12 to which razor blades 13 are secured. The head is provided with a pin 14 which seats in a socket in the plate 12. The head portion 10 and the plate 12 carrying the razor blades 13 are all preferably shaped in the form of an equilateral triangle on each side of which is provided a cutting edge for the razor. The blades 13 have holes 30 into which pins or 4 lugs 16 on either the head 10 or the plate 12 edges whereas the third side has an inner` curved edge as shown at 18. The straight edge 19 is hinged on a pin 20 to an edge of the plate 12v. A coil spring 21 surrounds the shaving.

seat to hold them in place. The blades are -serves to rock the hinged portion 19 to lift it away from the edge of the razor blade. When i so lifted it converts the adjacent razor bladete '13 into an ordinary straight razor. In other words the protecting ribs or teeth on the edge ofthe plate 12 are lifted away from the cutting edge of the razor so that the razorA` cuts freely and operates ina manner similar" :e5 to the ordinary straight razor. The stud 11 is screw threaded and on its end carries a sleeve 23 to whichv is secured an arm 24, the arm carrying a screw threaded pin 25 on its..l` outer end. On its inner end the sleeve 23"3l rcarries a small pin 26which is adapted to seat in any one of several holes 15 inthe rear of the plate 12. The purpose of this pin and kthe holes is to provide meanslfor holding the arrn 24 in any one of several adjusted positions with respect to a side of the razor. The sleeve 23 carries a nut 32 which may be turned down to engage the finger 22 to hold the hinged side 19 away from the cutting edge of the blade. A handle 27 having screw so threads on the interior of one end is threaded over the pin 25. Ordinarily the handle will be offset as indicated in Figure 5 so that in shaving, the razor bladeswill be moved at an angle to the beard and thus facilitate easy' s;

A screw cap 28 is provided for holding the sleeve 23 in place on the pin 11. If it is desired, however,the user may attach the han'dle 27 directly to pin 11 thus eliminat-4 ing the sleeve 23 with its associated elements. "90 The handle 27 has a threaded end which carriesa nut 29. When usingpin this fashion the nut 29 may be screwed down upon thepin 11 as shown in dotted lines in Figure 2 to engage the linger 22 and swings the side 19 away 95 from the cutting edge of the razor blade. This provides an ordinary straight razor out of this side of the blade. The other two sides of the blade, however, still function as safety `razor edges. In shaving, the edge 19 may two cutting edges.

operate as an ordinary straight razor simply In witness whereof, I have hereunto set by pressing against the hinged edge 19 to my hand and seal at Indianapolis, Indiana, swing it away from the cutting edge of the this 8th day of December, A. D. nineteen hunrazor or if the operator so desires the nuts dred and thirty-one.

29 or 32 may run down to engage the nger 22 and permanently hold the edge 19 away from the cutting edge of the razor blade so that this edge of the razor will remain 'as' a straightiblade.

Instead of having each edge madeina'separate piece the razor may be-made-inthefform of a one-piece blade 3l as shown in Figure 4, this blade being provided with threev .cutting edges, thus insuring a relatively long cutting life as distinguished from safety razor blades as heretofore known which have only Onejparticular advantage secured by this razor over the ordinary safety razor Yis'thatv the angular portionsv at .theapexes o-f'thetr'iangle enable the'user to ,positi'o'nthe razor about certain portions of the face not easily accessible vby ordinary 'razors and thus operate more efficiently, parti'cula'r'lywhen lshaving adjacent the nose and the lower lip.

`It willbe obvious to those skilled in the art that various'c'hanges maybe made in my device Vwithout departing from the spirit of the invention and therefore I do not limit myself to what is shown in the drawing and described inthe specification, but only as indiea'ted'by the appendedr claims.
