Application filed November 10, 1927, Serial No. 232,220. .Renewed. February 18, 192s.

One of the objects of my invention is to provide a'safety razor in which the guard for the blade edge will serve-as an actuating member for rocking or rotating the blade for sharpening the blade edge.

Another object of arrange the parts of the razor that when the guard and the blade are out of shaving relation the blade may be folded Within the razor frame for storage and transportation.

In carrying out my, invention I provide a frame, a guard member-pivotally "carried by the frame,ja blade holder pivotallycarriedby the frame, means to retain the guard member and the blade in shaving relation, and

means cooperative between the guard member and the blade holder, when the guard member and the blade holder are out of shaving relation, for causing rocking or rotation of the blade forsharpening its edge when the guard member is .reciprocated in contact with a sharpening surface. 7 Myinvention Comprises novel details of improvement that will be more 'fullyh'ereinafterset forth and then "pointed out in the claims. 7 I I v I Reference is to be had tothe accompanying drawings forming a part hereof, wherein Fig. 1 isa side view ofa safety razor embodying my invention;

Sim1lar numerals of reference indicate corresponding parts in the several views.

' The frame 1 of the razor is shown comprising a base 1' and spaced uprights 1 to which base a handle Q is'attached in any desired or well known way, such as by riveting.

A pair of spaced arms 3 are pivotally supported at 4 upon and between the uprights I 1", and said arms at one end are shown connected by'a crosspiece 3 serving as afinger the invention is to so Fig. 2 is a verticalsection throughFig. 1

'piece'formanipulating thearms The'parts 3 and 3f serveias' a frame pivotally carried by frame 1'; Between the arms'3 a guard memherb is journale'd, as by pivots5 atthe ends ,of s'aid'guard member rotative in bearing holes in the'arms 3. In; the example illus trated the guard member 5 is shown the form of a roller having'a recessed mid-port1on 5 between spaced annularprQ ectmg surfaces,5 ,that are adapted to engage a faces 5 of the guard member whenthe parts to sharpening or stropping' surface 6. blade I .7 is adapted to rest upon the projecting-sun between the guard member and the blade edge for.cle arance at the blade for lather during.

shaving. AtS is indicated a bladeholder which may be of any suitable construction and is pivotally supported between theuprights 1". Said blade holder is shownprovlded with pivots 9 atopposite corners,.which are journaledin holes in the uprights-l The blade holder illustrated comprises a plate 8 having ears 8 at opposite corners, from which the pivots 9 extend. The blade holder isprovided with gears 10 shown located at the pivots 9 for 'rotatingtheblade holder,and the guard member .5 is shown provided with gears llwhich areadapted to meshwith the gears 10 when the guard member is folded toward and adjacent to the blade holder, as

indicated in Figs. 2 andlO. Tl1e blade holder plate 8 is provided with laterally disposed stops or lugs 12 at its .ends near the front corners,,which lugs extend edgewise beyond the plate, which plate'is shown recessed at its 7 ends at 8, (Fig. 3), and said lugs are shown offset from the plane ofplate8. The arms 3 are shown provided with projections or fingers 13 which are adapted to overlie stops 12 when the parts are in shaving relation to re tain the blade upon the blade holder, (Fig. 1). Said projections are shown extending inwardly respecting the planeof arms 3 to engageithe stops -l2 -whichare spa'cedapart a distance less .thanlthe-distance between said arms to permit] the blade holder to swing between said arms, (Figf3); As illustrated,

the arms 3 at the inner portions of the projeetions or fingers are'providedfwith re s the stops 12 to retain theparts, and the inner edges of the projections 13 are shown i1iclined at 13 respecting the stops12 so as to engage and slide along said stops when the parts are being assembledin shaving posivtion, 1
