To all whom-it 'iri'a-y concern: i

Be itknown that- I, lVILLraat BJWE'rM-UR,

a citizen of the United States, residing at Montro'sc, in the county of Susquehanna, State of Pennsylvania, have invented 'cer tain new and useful Improvements in Safety- Razors; and I do hereby declare the following to a be a full, clear, and exact description of the invention, such as. will enableothers appertains to as the blade is worn away the guard plates can be adjusted in accordance with the change of form ofthe blade.

With these and other objects in view, the invention consistsin certain novel features of construction as hereafter shown and described and then specifically pointed out in the claims, and in the drawings illustrative of the preferred "embodiment of the invention, Figure 1 is a side elevation of the improved device. Fig. 2 is a plan view ofthesame. Fig. 3 is an end elevation. Fig. 4 is a section enlarged on the line t-1- of Fig. 2. Fig. 5 is a perspective view of the base meniher detached. Fig. 6 is a perspective view of the blade detached. the tun-part guard plate in perspective and detached. Fig. 8 is a perspective view of the clamp plate detached. Fig. 9 is aperspective view of a modified form of the twopart guard plate. Fig. 10 is a perspective view of the modified form of the clam plate which will be employ-ed with the moditied form of-the guard plate shown in Fig. 9. The ii'nproved device comprises abase plate or member 10, preferably diamond shaped and with a concaved upper face'and a convened lower face and provided'with upwardly directed studs 11--12 at the ends and a threaded stud 13 extending vertically from the center of the base plate. The blade is represented at 14 in Fig. 6, and is preferably formed with a convex-lower face to conform to the convexed base plate, and

is likewise provided with recesses 15-16 at' its ends to engage with the studs 1112, and is also provided with a central aperture 17 through which the stud 13 extends.

Fig. 7 represents I {Bearing upon't-he plate lat is a two-part guard member formed of two relatively thin' plates l3-19 with. recesses 20'-91 in their confrontmg'edges adapted to tit-around the Patented Feb."15, 19 10.

threaded stud 13. The outer edges of the guard members 18.19 are provided with spaced guard teeth or fingers 22 23 of the usual form. 'Rising from the plate 18 are spaced studs 24, and risii'ig-from the plate 19 are-similar spaced studs 25, the-studs 2 1-25 being arralwed-in alinement transversely of the guard plates, as shown.' A clam 26 having spaced slots 27 through which the studs Qtlr-25 extend, and likewise provided with an aperture 23 through which the stud 13 extends,'bears upon the plates. The handie member of the improved device is rep resented at 28 and is provided with a threaded aperture in its lower end adapted to eugage over the threaded stud 13, and'thus form a clamping means-whereby the members of the device maybe firmly compressed .and held in position. By this simple meari'sit will be obvious thatthe-plates 18-19 may be adjusted toward and away. from each other to conform to the position of the cutting edges of the blade 14 by simply lo0sening the handle 28 which will release the blades and permit the requisite adjustment. Thus when the blade It requires regrindin the plates 18-19 may be readily adjusted to tiechange of location of the cutting edges, as will be obvious. In event of one of the cutting edges becoming nicked, the plate can be ground to remove the 11icl ,'and the plates 1S19 then adjusted to a still greater extent to locate the fingers 22-23 in the proper position relative to the change of form of the newly ground cutting edge. With this improveddevice ifthe nick be near one end of the blade, the blade may be reground at an incline, or just sufficient, to remove the nick, and thus avoid the necessity for cutting away the uninjured portion of the blade, and the at a correspondin incline, the slots 2-7, and the pins2 l-25 eing sufficiently loose tt permit this slight oblique adjustment.

In Figs. 9 and. 10 a slight modification in the construction is shown coiisisting in arranging the pins 2425 in staggered relations, or out of alinement transversely, and forming the slots 27 likewise in staggered relations. This modification in the. construction of the device may be advantageous under certain circumstances, but it will-be p plate A guard plate adjusted obvious that this slight modified form does not constitute a departure from the invention,'or sacrifice an of its advantages, as the operationofthe, evice produces the same result inboth forms of the device.

What is claimed is A 1. A safety razor comprising a base member having a threaded stud, a, blade bearing upon said base and over said "stud, a twopart guard member-hearing upon said blade and provided with guide studs, a clamp plate bearing upon said guard plates and provided with slot-s through-which said guide studs extend, and a handle having a threaded aperture engaging said-guide stud and clamping the parts together.

2. A safety razor comprising a base meniber'having a concaved upper face and a convexed lower face and with' upwardly directed studs at the ends and a threaded stud extending therefrom intermediate the ends, a blade having a convex lower face and bearing upon the coueaved face of said base and over said'stud, a two-part guard In ember bearing upon said,b1ade and provlded with guide studs, a clamp late bear-.

ing upon said guard plates an provided with slots through which said guide studs extend, and a handle having a threaded aperture engaging said. guide stud and damping the parts together,

In testimony whereof, I affix' my signature, in presence of two witnesses.
