Patented June 17, 1930 WILSON J'. BREA'UX, 0F ORLEANS, LOUISIANA i VRAZCJIi.-BLADE SHARPENER Application filed Mareh15, 1928. Serial No. 261,960.

My invention relates to improvements in razor blade sharpeners, andis more especially intended for use 1n sharpening blades of safety razors.` In ordinary practice, these 5 are generally used until they become dull, and

then are thrown away, but Y the herein described invention is intended to provide a cheap, simple and efficient apparatus "which may be used for `re-sharpening such blades,

or, if desired, for sharpening ordinary razor blades; but it is more especially intended for use in 4connection withv safety razor blades, since these are more commonly used and more `conveniently sharpened in an apparatus of the character described. Y

Accordingto my invention, the razor blade may be drawn longitudinally over a stone or sharpening pad, and at the same time will be automatically given a transverse movement 2o while the apparatus provides for conveniently turning over the razor blade at each end of the stroke. v

My invention will be more fully understood Aafter reference to the accompanying` drawings, in which like parts are indicated by similar reference symbols throughout the several views, and in which Figure l is a plan view of the complete ap paratus in use. e

Figure 2 is a side elevation of the device with the handle omitted for the sake of clearness in the drawings. v

Figure 3 shows a section along the line 3-3 of Figure 1, and looking in the direction of the arrows.

Figure t'shows a section along the line 4 4 of Figure 2, and looking down, parts being shown in elevation.

Figure 5 is a sectional elevation of the sliding frame and handle, on which the razor blade is carried in the operationof sharpening same, and

Figure 6 is a detail view showing the razor blade and its holder, andthe parts being 'N shown in full lines for. movement iny one direction, and in dotted lines for movement in the reverse direction. A represents a housing block hereinafter y called a holder. For convenience of manipu- 5 lation, the holder may be provided with a handle a. socket a.

The stone or pad B, on which the razor is sharpened, is held in such a way as to pro-` ject above the top of the holder, as shown in Figures 2 and 3. i o Y Secured beneath the holder is the base block D which is spaced from the holder, as by the transverse `strips C and C securedto the base block b y means of the nails E or any other convenient way.V

By this arrangement, an open slot is left between the holder and the base block.

The base block D is providedwith guide This holder is provided `witha ways D and D2 preferably re-inforced with metal, and may be secured to the base block in any convenient way as by means of the nails E, see Figure l. These guide'channels DjandD2 are divergent as shown.

F represents the sliding frame carrying the razor `blade to be sharpened, which sliding frame is operated by the handle F revolubly connected thereto in any convenient way; as shown, for instance, in Figure 5, in which Figure G represents a pin secured in the handle by means of the cross pins g, and provided Vwith a squared portion g adapted to engage the pinion H which is held against turning on pin G. This pin G is journalled as at g? at one end of the sliding frame.

The sliding frame F has one end ianged upwards as at f to form a journalled bearing forone end of the shaft L, and the other end f -is also flanged upwards and bent overon itself as at f2 to form a casing for the block fr* shown as at the leftof Figure 5. Journailed at this end of the casing are the .idler I andthe pinionK carried by the end of theshaft L. Thusy the rotationof the handle F through an'angle will cause the shaftL` to be also rotated through an angle. l

The bottom of the sliding frame carries a pin f* preferably carrying an anti-friction roller f5, which roller engages in the guide ways D andD2, and imparts a transverse motion tothe sliding frame as it ismoved longitudinally, as will be hereinafter described.

' The shaft Lis attened as at Z, see Figure 3, to engage the blade holder M which is 'in the form of a clip held against turning onV NT OFFICE said shaft, and which holds firmly in place below the housing block, transverse spacing the razor blade N which is to be sharpened.

` The operation of the device is as follows:

The operator grasps the handle a of the holder with his left hand, and with his right hand grasps the handle F of the sliding frame F, and turns this handle so that the gears H, Iand K arerotating the shaft L, so

that the blade Niwill bear on the 4surface of the sharpening element B. This element, 'as

before said, may be of stone, a leather pad, with or without abrasive material, or any other sharpening element which may beV de sired to use in connection with the holder. Bearing with the proper pressure on the top ofthe sharpening element, as shown in Figure 1, and moving the traveling frame to the right Y of said figure, the roller fo engagingin the grooves D and D2 will cause the traveling fra-me to move transversely of the sharpen-y ing element, at the same time it is moving longitudinally of said element, thus sharpening the edge of the blade from one side. yWhenl the traveling frame-has been moved as far as possible in one direction, turn the handle F` so as to shift the razor blade from the position shown in full lines in Figure 6 to that shown in dotted lines in said figure, and move the traveling frame in the opposite direction. During this movement, Athe opposite side of the razor blade will be sharpened. Gf course,

in the operation of the device, the razor blade j should be pressed down upon the abrasive surface with sufficient force to secure the desired abrasive effect.

A few vibratory movements of the traveling frame, if same be properly manipulated,

will soon put the desired edge on-the razorV blade..

The razor blade may be conveniently inserted in the holder and removed therefromof parts might be made, which could be used l without departing from the spirit of my invention, and Ido. not'mean'to limit the invention to such details, eXcept as particularly pointed out in `the claims. Y v

Having thus described my invention, what I claim and desire to secure by Letters Patent ofthe United States is:

1. A hand razor blade Sharpener coin-pris-V ing a handle and a housing block projecting forwardlytherefroin, said block being Vprovided with a recessed upper face :and a plane lower face, an abrading block held in the recessin the upper face,a base bloclr mounted strips interposed between the ends of said housing block and said baseblock and spacing the two apart, said base block having a V-shaped groove in its upper surface, a blade holding frame provided with a cross bar projecting through the space and between said housing block and said base block, and slidable both longitudinally and laterally in said space', said frame having a projection engaging in said groove, a rotatable blade clamp carried by said frame, a handle rotatable attached to said frame, and means actuated by rotating said handle for rotating said clamp. 2. `A hand razor blade Sharpener comprising a handle and a housing block projecting forwardly therefrom, said block being provided with a recessedV upper face and a plane lower face, van' abrading block held in the recess in the uppery face, a base block mounted below the housing block, Vtransverse spacing stripsY interposed between the'ends'of said housingbloclr and said base block and spacing thetwo apart, said base bloclr having a V- shaped groove in its upper surface, a blade holding frame provided with a cross bar projectingthrough the space and between said housing block and said base block, and slidable both longitudinallyand laterally in said space, said frame having a projection engagvVlLSON J. 13R-EAUX.
