SAFETY RAZOR.

Application filed March 9, 1923. Serial No. 623,992r

To all whom it may concern:

Be it known that I, WILLIAM G. ADAMs, a citizen of the United States, residing at Roanoke, in the county of Roanoke and State of Virginia, have' invented a new and useful Improvement in'Safety Razors, of which the following is a specification, reference being had to the accompanying drawing.

My improvement relates to a safety razor structure wherein provision is made for conveniently turning the blade so as to bring first one side and then the .other side of the blade against the face during theshaving operation, whereby the blade may longer be kept in cutting condition.

A structure for this purpose is described in my application for Letters Patent, Serial Number 57 8,37 7, filed July 29, 1922. In the form described by that application, the blade carrier member turns on an axis which extends in the direction of the length of the handle of the structure. `The object of the present invention is to provide a structure in which the axis of the carrier member is parallel to the cutting edgeof the blade.

In the accompanying drawings;

Fig. l is a side elevation of a safety razor embodying my improvement;

Fig. 2 is an elevation of the same structure looking toward the left'as shown in Fig. 1, the greater part of the handle being broken away;

Fig. 3` is an upright section on the line,

-"3 3, of Fig. V1, looking toward the right;

Fig. 4 is a section on'the line, 4 4, of Fig. 1;

Fig. 5 is a perspective of another form of the structure;

Figure 6` is a rear elevation of the same structure, portions being broken away;

Fig. 7 is an upright section onl the line, 7 7, of Fig. 5, the yoke-form carrier member being turned away fromthe guard and the blade .and the blade holder being turned transversely to the plane of the carrier member;

Fig. 8 is a detailview of the yoke-form carrier and the blade holder; Fig. 9 yis a section on the line, 9 9, of Fi eferring to said drawings, A is the usual handle. B is the guard support which rises obliquely from the upper end ofthe handle.

'C is the guard. In the form shown by the drawings, the guard is integral with the support B. D is the blade having a back,

D1, ,which is engaged in the blade holder, E. Said holder is pivoted to the carrier member, F, on an axis which is midway between the ends of the blade and perpen dicular to the cutting edge of the blade and parallel to the plane of the blade.v The holder, E, has a journal, E1, resting in a bearing, F1, formed in the carrier member, F. At the side ofthe holder opposite said bearing the holder has a head or handle, E2, adapted to be grasped by the hand for turning the holder in said bearing.

On'the support, B, are two bearings, B1, formed by cutting a tongue from each side yedge of the support and bending said tongues backward, whereby the axial line of the two bearings isl placed outside of the body formed by the support and the guard. The carrier member is of the same length as the length of the guard the dimension of the guard parallel to the carrier yinember. At each end the carrier member has in its lower part an eye, F1, through which the tongue forming the adjacent bearing extends. By this means the carrier member is hinged to the unitary body composed of the support, B, and the guard, C.

\ At the middle of the carrier, F, a tongue, F2, extends downward into a slot or aperture, B?, formed in the adjacent part of the support, B. On the inner face of the support, B, is a blade spring, B3, secured to the support by rivets, B4. The-middle part of said spring extends into the path of the tongue, F2, and presses said tongue rearward the contact between the spring and said tongue being below the axial line of the bearings, B1, whereby strain is exerted upon the carrier member in the direction which 1 causes ,the blade, D, to be pressed against the guard,`C, when the carrier member and the blade are in the working position.

When the blade is to be reversed, the carrier member :and the holder and the-blade' are' again turned on the axial line of the bearings, B1, into the working position.

The guard and the blade and the blade back may be of any ordinary construction. In the form illustrated by Figs. 5, 6, 7, 8

In said form we have the handle, A, the

support, B, andthe guard,C,y as before.

i the holder, H, andthe bladeare turned half way by the hand engagingthe handle, H3,

The yoke-form carrier member, G, has arms, G1, extending alongI the ends of the 4guard and hinged at, G2, to the forward part of the guard, in a line parallel to and a little forward of the cutting edge of the blade, D. The blade back, D1', is engaged by tlree tongues, H1', forming parts of the holder, H, two of said tongues being at one side and the other at the other yside of said back, The holder has a journal, H2, .resting in abearing, G3, -formed in the carrier member. Outside of said bearing .said journal 'sup ports a head or handle, H3. Toythe rear of the support, B, are `secured two spring tongues, G4, whichv extend into the lpath of and engage the body of the yoke-form carrier member when the latter is in its working position, atwhich time the blade, D, is also in its working position, its cutting edge bearing againstthe guard. Y

When the blade is' to be reversed, the rear part of the yoke-form carrier member is pressed ward out of engagement with the tongues,- G4, and forwarded into the position indicated by dotted lines in Fig. 7. Then this turning being on the axis of the journal, H2, and the bearing, G3. When this halfturn has been made, the yokeform carrier member is again drawn backward into engagement with the tongues, G.

It will now be observed that -in each of these two forms, thel carrier member is hinged-on an axis which is parallel to the cutting edge of the blade, the hinge line in v ends to the carrier member on an axial line transverse to the hinge line of the carrier one case being at the rear of the blade and in the other case being near and at the front ofk the blade. It will also be observed that in each form the blade may be reversed with` out detaching the blade from the remainder of the structure.
