. Specification of Letters Patent. Patented Feb. 15, 1910.

' Application filed November 24, '1908. Serial No. 464,276.

To all whom it may concern:

Be it known that I, CHRISTOPHER W. LE- VALLEY, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have in- Vented certain new and useful'Improvements in Safety-Razors, lowing is a specification.

My invention relates to a safety razor and stropping device, and has for its object toproduce a razor of this ty e having novel means for positioning the blade upon the supporting plate or base and there holdand a device connected to the razor adapted to hold the blade for strop ing, all of the parts of which article are a apted to be taken apart and compactly arranfged for carrying. Re erring to the drawings-Figure 1 is a perspective view of the razor and blade holder. Fig. 2 is a top planview thereof, the razor blade being removed and theblade clamps extended; Fig; 3 is a central longitudinal section on the line 3-3 of Fig. 2. Fig. 4 is a perspective view of the stropping device in open position. Fig. 5 is a plan view of the razor blade, detached. Fig. 6 is a crosssectional view of one of the pivoted blade clamps.

In the drawings, 2 indicates the razor hantubular construction and havin at 1ts uppe threa ed pin 2, adapted to engage with the holder 3. This comprises a flat plate rovided with a suitable guard 3' along its ront edge which may be formed by bending the plate at right angles and providing the bent edge with slots or apertures. plate 3 is made, is formed, preferably by pressing, to have an out-ward extending boss or projection 20, and a corresponding recess or socket on the inner side.

, In the wall of this socket is formed a screw-threaded aperture to receive the pin 2' of the handle.

A flange 5, constituting a finger rest and a guard for the rear or unused edge of the razor blade, extends along the edge of the boss 20 and referably extends a little beyond the surIace of the blade holder. By thus forming the blade holder the pin 2 of the handle is prevented from coming into contact wit-h the razor blade 4 when in place upon the holder 3 even though its end projects some distance beyond the socket wall.- The holder plate 3 is also recessed at its opof which the fol-' holder is stiffened longitudinally, while F end a' projecting screw- 1 The metal of which the supporting posits ends, as at 6, 6, so that the blade may e easily grasped and removed or replaced when desired.

The blade securing means comprise a pair of swinging clamps 7 7, pivoted to the opposite upper or rear corners of-the holder Each clam preferabl consists of a iece of metal fol ed on itse f and adapted" to be swung into the position indicated in Fig. 1 where it clasps the holder 3 and blade 4 that may be placed thereon between its two oppositely disposed portions. Along the folded edge of each clamp there is an inward projecting lug 8 adapted to register with a notch 4 on the end 0 the razor blade 4:, and thus position and holdthe blade. In order to further assist and insure that the blade shall occupy exactly the proper position on the holder, I prefer to provide it and the plate on which it rests with some sort of interlocking means, such as depressions 8, 8, in the plate 3 and projections or studs 8 in the blade 4. It is obvious that other forms of interlocking means mi ht be used. Itwill thus be seen that by Forming the plate 3 with 'a guard having a continuous bar along its lower edge and the flange 5 on its upper or rear edge, theplate or blaille t e clamps 7, 7 operate to stilfen the plate transversely or along its opposite sides.

The stropping device or holder for the blade while being stro ped is indicated at 9. It comprises a pair 0 plates 10, adapted to hold the razor blade between them and provided with looking devices 11 to engage with the locking studs 8 on the blade. The two plates are hinged together at their outer ends, as indicated at 12. The oppositeor inner ends are shaped into a sort of handle that is adapted to be insertedinto the outer open end ofthe razor handle 2.

In order to securely grasp the blade betweenthe clamping plates. 10, I prefer to' provide a swinging clasp l4, pivotally mounted on the outer end of one of the plates. The clasp 14 is preferably of U- shape in cross section and when swung into position firmly holds the two clamping forth.

2, In a safety razor, the combination witha blade holder recessed at its opposite ends, of a removable blade mounted thereon, a handle, swinging clamps, and registering means on said clamps and blade for holding the latter in position, substantially as set 3. In a safety razor,the combination of a blade holder recessed at its opposite ends, a removable blade supported on said holder, a pair of swinging clamps, and means on said clamps for engaging with the blade to hold it in position, substantially as set forth.

4:. In a safet razor, the herein described blade support ormed of thin metal, having an upper face upon which the razor blade may rest and formed with a guard alon its front edge and with an outward exten ing hollow boss or projection near its rear edge,

substantially as, and for the purposes set forth.

5. In a safety razor, the herein described blade support formed of thin metal having an upper face upon which the razor blade may rest and formed with a guard'along its front edge, an outward. extending hollow boss or rojection near its rear edge, and a boss, the Wall of which is perforated for the attachment of the handle, means forholdl ing the blade upon the support, and a handle detachably secured to .the boss-of thesupport.
