GAISMAN, NEW YORK, N. Y., ASSIGNOR, BY MESNE ASSIGNMENTS, TO GILLETTE SAFETY'RAZOR COMPANY, OF BOSTON, MASSACHUSETTS, A CORPORATION OF DELAWARE SAFETY RAZOR Application filed September 19, 1928. Serial No. 306,926.

The object of my invention is to provide a safety' razor in which a pivotal guard having stops to engage a blade edge will be retained by spring pressure in shaving position with the stops engaging the blade, and

` in which the guard will be held positively out of shaving relation lto the guard when for shaving, said projection being adapted to engage the abutment to positively retain the guard away from the blade when the guard is out of shaving relation to the blade.

- e My invention also comprises novel details Y of improvement that will be more fully hereinafter set forth and then pointed out in the claims.

Reference is to be had to the accompanying drawings forming a part hereof, wherein Fig. 1 is a side view of a safety razor embodying my invention; Fig. 2 is a section on line 2, 2 in Fig. 1; Figs. 3, 4, 5 and 6 are sectional views showing the parts in different positions, Fig. 5 being a section on line 5, 5 in Fig. 2, and Fig, 7 is a plan view of the guard. j

Similar numerals of reference indicate corresponding parts in the several views.

The numeral 1 indicates a main frame of the razor shown provided with spaced uprights 2 in which a blade-holder 3 (of any desired orwell known construction) is carried by a shaft 4 journaled in said uprights, all in a well known way. A roller 5 is also A shown journaled in said uprights and provided with a gear 6 in mesh with a gear 7 carried by said shaft 4 for rocking the blade holder when reciprocated along a strop 8 to sharpen the edge of blade 9. The frame l is 5G shown provided with a handle 10, and with spaced strop-tensioning members 11 and 12. f

A guard 13 is rovided with stops 14 (shown in hook-like orm) for retaininor the blade by engagement therewith at its edge portion. The guard is pivotally supported on frame 1, at one side of the handle, being shown provided with laterally extending ears or lugs 15 pivotally attached by rivets 16 to laterally extending ears or lugs 17 carried by frame 1, the ears 17 being shown extending from the strop-tensioning member 11. The guard member is shown provided with an opening 18 freely receiving the handle 10, whereby the guard may be manipulated by engagement of a finger with the extending portion of the guard member at 19, on the side of the handle opposite the stops 14.y

The guard member 13 is shown provided with a spring-like projection or finger 20, which may be formed by cutting away the metal of the guard member at 21, (Fig. 7 The projection 20 is adapted to engage an abutment 22 on frame 1 for retaining the guard member in different positions. The abutment 22 is shown on the strop-tensioning member 11, and said projection. may be formed by pressing out or embossin the metal of ymember 1, said abutment being shown provided with a curved outer surface to be engaged by the projection 20. Said projection engages the abutment 22 in a spring-like manner.

- Vhen the guard and the blade are in cooperative relation for shaving the projection 2O will engage the abutment 22 with spring action, at a point behind the centre of the abutment, and the abutment will enter the cutaway portion or opening 21 at the free end of the projection to permit the engagement of the abutment and the projection as shown in Fig.3 and thereby the projection will retain the blade edge in engagement with the stops or hooks 14 to retain the guard resiliently pressed with respect to the blade edge. vWhen the guard member is tilted or turned on its pivot 16 from the position shown in Fig. 3 to the position shown in Figs. 4 and 5 the projection 20 will flex and slide along the abutment 22, sothat when the guard is moved .sufficiently tov assume the position shown in Y Fig. 6 the projection 2O Will lie against the i abutment 22, as at a point Withoutlits course and 'thereby the guard-Will be positively retained away from the blade retaining position,andin a position Vfor stropping the blade edge, as indieatedin Figli.
