HEINRICIIWOLFERTS, OF OHLIGS, NEAR SOLINGEN, GERMANY.

RAZOR.

SPECIFICATION forming part of Letters Patent No. 512,596, dated IJanuary 9, 1894.

Application filed August 17, 1893.

4a new and'improved razor-handle; and it consists essentiallyin `al'razor-handle composed of two hollow pressed sheet-metal shells, a

xpivot extendingthrough the shells, a blade mounted on the pivot, and concave-convex disk-shaped -springs mounted at ,their centers on the pivot and having their free marginal edges facing each other and bearing directly upon the razor-blade at points remote, or at a distance from the said pivot.

The invention is illustrated by the accom-- panying drawings,in which- Figure l is a side elevation of the improved handle, the front pressed sheet metal shell being artly broken away. Fig. 2 isa plan View part in section on the line -0c,Fig. l; and Fig. 3 is a Sectional View on the line y-y, Fig. 2. In order to enable those skilled in the art to i make and use my invention, I will now describe the same in detail, referrilfg to the drawings, wherein- The letter a indicates two hollow sheet metal shells pressed into form. These shells are connected at one end by a rivet d and an interposed filling piece c against which the shells rest. The opposite end portions of the shells are connected by a pivot b on which the razor-blade lois mounted and adapted to swing.

The concave-convex disk-shaped springs f, formed of sheet steel, are placed vwithin the hollow sheet metal shells, and at their centers they are mounted on the pivot b in such Serial No.483,363. (No model.)

manner that the free marginal edges of the disk-shaped springs bear upon the razor-blade 7c at points remote, or at a distance from the pivot b, thereby obtaining extended bearings by which frictional resistance is increased andr the springs are rendered superior in action to that construction where the springs only have very small bearings at their centers upon the blade. .'Ilhe marginal edges or rims of the disk-shaped springs are curved outwardly to form smooth bearing surfaces which oer sufcient resistance to render it possible to rivet the thin sheet metal shells together by means of the pivot b, so that the springs are somewhat compressed and spread at the rims upon the razor-blade. This pressure is advantageous, since the blade at its pivoted part does not touch the shells, but is given an extended bearin g on the free marginal edges of the diskshaped springs which assures the position of the blade at alll angles and gives the blade an even swing. v

Having thus described my invention, what I claim is- A razor-handle, consisting of two hollow pressed sheet-metal shells a, a pivot b connecting the shells at one end portion, and concavo-convex disk-shaped springs f arranged within the hollow sheetmetal shells and mounted at their centers on the said pivot with their free marginal edges bearing upon the razor-blade at points remote or at a distance .from said pivot, substantially as and for the purposes described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
