NEW YORK, N. Y.

CUTTING-BLADE ron RAZORS.

Specification of Letters Patent.

Patented June '7, 1910.

Original application filed January 14, 1905, Serial No. 241,129. Divided and this application filed May 23, 1905. Serial No. 261,774.

To all whom "it may concern:

Be it known that I, WALTER J. SMART, a citizen of the United States, residing in the borough of Brooklyn, in the city of New York and State of New York, have invented a new and useful Im rovement in Cutting- Blades for Razors, 0 which the following is a specification.

- This invention relates to safety razors of the ty e disclosed in my pending application, erial No. 241,129, filed January 14, 1905, of which the present application is a division.

The objects of the invention are to improve and simplify the construction of the razor frame and blade; furthermore, to increase their efiiciency in operation, and to decrease the expense attending their manufacture and use. With the foregoing and other objects in View, which will appear as the description proceeds, the inventlon resides in the comination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of the following claims without de arting from the spirit of the invention.

11 the accompanying drawing forming part of this specification, Figure 1 is a plan view of an improved form of blade adapted to be used in connection with my safety razor. Fig. 2 is a plan view of the razor, partly broken away, with the blade in position ready for use. Fig. .3 is a side elevation of the improved razor and blade.

Like reference characters indicate corresponding parts in the difierent figures of the drawing.

The improved blade which I refer to use in connection with the razor o the present invention is designated by the reference letter B, and consists of a thin, fiat, plate-like piece of steel or other suitable material, preferably of narrow width and havinga sharpened'cutting edge. As usually made, the blade is of substantially uniform thickness. The blade B preferably is provided with end projections or handles having forward surfaces 11-11 and rearward surfaces 9.).

The razor construction which I prefer to employ comprises a curved razor frame 2 having a handle 3. The frame 2 is formed 2 in the present instance consists of downwardly bent ears or lugs 6, which are pivotally connected with the frame 2 by means of pins 7 projecting from the side edges of said frame. The ears or lugs 6 form abutments connected with the guard 4 of the frame 2, adapted to be engaged by the rear shoulders 9 of the end projections of the blade B for limiting the rearward movement of the blade, which is fitted between the retaining member or clamp 5 and the guard 4, as shown in Fig. 2., The end projections of the blade B extend beyond-the side edges of the frame 2 and guard 4 so as to form handles which can be grasped between the fingers in removing and replacing the blades. When a blade B is in position as illustrated in Fig. 2 the pivotal retaining member 5 contacts with and supports the same along its cutting edge.

The means for holding the pivotal retaining member 5 securely against the blade B referably consists of a coil-spring 8, whlch is interposed between the retaining member 5 and the frame 2 in rear of the pivotal connection between said retaining member and said frame. When it is desired to remove the blade B it is only necessary to press the rear endof the retain ing member 5 toward the frame 2 and to grasp the blade B with the fingers by means of the end projections or handles on said blade.

The end projections of the blade B preferably are located close to the forward cutting edge thereof, whereby the pivotal points- 7 of the retaining member 5 are located close to the cutting edge of the blade so as to enable the spring 8 to exert considerable leverage on the retaining member 5, and

.thus hold the cutting edge of the blade securely in position.

Having described my invention, I claim, 1. As a new article of manufacture, a thin, flexible, approximately-rectangular blade having a forward cutting edge and end projections located close to said cutting edge, substantially as described.

2. A safety razor having a guard, a

clamping member provided with downforward edge thereof with downwardly bent lugs pivotally connected with said guard, and a flat blade having end projections extending beyond the ends of said guard and resting against the lugs, of said clamping member, said blade being fitted between said guard and said clamping member, substantially as described.

. at. A safety razor having a guard, a clamping member having downwardly bent lugs adjacent the forward edge thereof, said lugs being pivotally connected with said guard adjacent the guard teeth thereof, said clamping member having a rearwardly extending finger-piece, a coil spring interposed between said guard and the finger-' name to this specification in the presence of two subscribing witnesses.
