* UNITED STATES JOHN FRANCIS OMALLEY, OF NEW YORK,

SAFETY RAZOR.

Application filed October 14, 1926. Serial No. 141,561.

This invention relates to safety razors and has particular reference to a blade holder member especially designed for use in connection with blades of the double-edge flexible type, said holder being in the nature of an improvement over my prior United States Letters Patent No. 1,543,587, granted June 23, 1925.

In addition to facilitating the attainment -of the objer ts set forth in my prior patent,

the present invention comprehends, respectively, means for insuring the properregistration-of the edges of the blade with the teeth of the guard member; an improved means for adjusting the blade. edges with respect to the guard member, and 'an improvement in the means of connection between the guard memher and the head which greatly facilitates the operation of cleaning and drying the holder member after use.

With the above recited and other objects in view, reference is had to the following specification and accompanying drawings in which there is exhibited one example or embodiment of the invention which is in no way intended as alimitation upon the scope of the appended claims as it is to be clearly 'understood that variations and modifications which properlyfall within the scope of said,

claims may be resorted to when found expedient. In the drawings Figure 1 is a side view of the razor illustrating, respectively in full and dotted lines,

the closed and open positions;

Fig. 2 is a top plan view thereof with parts broken away to disclose the underlying structure; 7

Fig. 3 is an end Viewthereof;

Figi- 4 is an enlarged fragmentary detail sectional view taken approximately on the line 44 of Fig. 2, and illustrating in full and dotted lines the adjusted relations of the head and guard member;

Fig. 5 is a fragmentary perspective view of the guard member; I

Fig. 6 is a plan view of the blade removed from the blade holder member.

Referring to the drawings by characters of reference, 10 designates the handle to which the guard member 11 is rigidly attached, the handle 10 having a reduced terminal 12 projecting above the upper face of the guard member, the said terminal being of a non-circular configuration .to snugly fit within. the similarly formed opening13 of the blade 14. The guard member on its opposite longitudinal side edges, is provided registration of .the cutting edges ofthe blade with the guard teeth. A head 18 which is transversely convex on its under face 19 to coincide with the convexity of the upper face of the guard member, is hingedly connected with the guard member by means of a depending arm 20 havin a hinge knuckle 21 positioned. between t e spaced hinge knuckles 22 which are. secured to and; depend from the under sideof the guard member and I through which hinge knuckles a hinge pin 23 extends. 'The opposite end of the head 18 is provided with laterally spaced parallel depending bearing cars 24 within which an eccentric lever 25 is journale'd, the eccentric lever having a cam face 26, which cam face in addition to locking the head in closed relation to the guard member serves to permit of limited adjustable locked condition of the head with respect to the guard member to vary the flexing of the blade in order to regulate the spacing of the cutting edges with respect to the guard teeth whereby the nature of the shave may be varied. In order to accommodate the depending arm 20 and the bearing ears 24, the opposite ends of the guard member are formed with notches 27. The

head is further provided with a medial aperture 28 for accommodating th'etcrminal 12 of the handle. I

From the foregoing construction it will be seen that the head 18 may be swung to a position which fully uncovers the guard member for facilitating the application or removal. of the blade while exposing the said parts to' permit of the ready cleaning and drying of the surfaces. When swung to a closed position, the blade is clamped and maintained in applied relation against accidental displacement while the eccentric lever allows for variation in the flexing of the blade when thus secured in place. Furthermore, the guide lugs 17 serve to position and properly hold the blade in registration with the guard teeth, so that the cutting. edges are equidistant-1y spaced from the ends of the guard teeth.

It will be observed that the use of end lugs adjacent the corners of the device will prevent relative angular displacement of the blade and guard since the straight end edges of the blade fit accurately against the lugs. It will be apparent therefore that the end lugs serve the two-fold functional utility of preventing both endwise and angular dislacement relatively of the blade and guard. he'central lug 12 and aperture 13 do not need to fit together accurately as to length, but they may fit closely, respectively as to thickness and width. It is merely essential that the central lug shall prevent undue edgewise movement relatively of the blade and guard. There may be sufficient clearance between lug 12 and aperture 13 to permit at least slight edgewise adjustment relatively of blade and guard.

What is claimed is: h

1. A safety razor, comprising a guard having lugs as lts'ends and having a non-circular projection at its center, a handle secured to the guard, a blade having a central noncircular opening mounted on the guard with its ends against the lugs of the guard and the non-circular projection of the guard extending through the opening thereof, a head hinged at one end to the guard and having a non-circular opening into which the projection of the guard extends, and means on the head for securing the free end thereof to the guard.

2. A safety razor, comprising a guard having lugs at 1ts ends and aslot at its center, a handle having a terminal with flattened sides extending through the slot of the guard abov'ethe upper face thereof, a blade having a central slot, said blade resting upon the guard with its ends against the lugs of the guard and the terminal of the handle proecting through the slot thereof, a head hinged at one end to the guard and having an opening into which projects the terminal of the handle, and an eccentric on the free end of the head for clamping the head to the guard.
