Application lejd April.z 9,"

The present,inventionrelates to an improved product ot' manufacture which is such in construction as to permit it to be conveniently defined as a shearsl Sharpener, that is, Ian' implement whose lconstructif'in is such as to permit'i't yto be employed as an aid in sharpening scissors blades, shears blades, and similar cutting instruments such as are employed more exclusively in barber shops.

Broadly the improved device comprises a clamp or vise in which the blade to be sharpened is rmly held, together with a therein in any suitable manner.

roller guide to accommodate and aid manipulation of the abrasive tool for tiles or other' instrument'employed in sharpening the cutting edge of said blades.

A distinguishing feature of the vise is a wooden body which it includes which cooperates with the cutting blade and the clamping plate .to minimize objectionable metallic vibrations and noises during the sharpening operation.

Another and indispensible feature is a roller carrying plate which is adjustably mounted on the vise in a position to permit it to conveniently accommodate the reciprocatory strokes of the file.

Other features and advantages flowing from the seemingly new organization of parts will become more readily apparent from the subsequent description and accompanying drawings.

In the drawings:

Figure 1 is anV end view of the improved structure.

Figure 2 is a top plan view thereof,

Figure 3 is an enlarged fragmentary inside elevational view. y

In the drawings, the reference character 1 designates generally the improved vise. This is shown supported on an appropriate base 2. It comprises an elongated block of wood 3 on one side of which is a metallic clamping plate 4. This plate is adjustably mounted on bolts 5 passing transversely through the wooden block and anchored The screw threaded ends of these bolts project through and beyond openings in a clamping plate and carry washers 6 and retaining nuts 7 the nut being preferably of wing type. In practice, the blade to be sharpened isl clamped firmly between the plate 4 and the block of wood. As before stated, the block of wood is particularly important in that it y 19a.

substantially eliminates the metallic'clinkdependable The threaded ends of the bolts projectv through and beyond the elongated slots and this arrangement permits the plate to be adjusted vertically with respect .to the base 2. Observing the upper end portions of the plate 8 it'will be noted that these are provided with right angularly disposed flanges 13 having their upper end portions projecting above the top of the block. These projecting portions .are 'formed with openings providing bearings for reception of a retaining bolt 14 for a tile rest rolled 15 which is located between the upstanding portions of said flanges. Incidentally, it will be noted that the adjacent edge or corner portion of the wooden block is cut away as at 16 to provide clearance to permit free rotation of the roller.

In practice, the blade to be sharpened is clamped between the jaws ofthe vise, these jaws being formed by the parts 3 and 4 already described. The pointed end of the blade is preferably arranged on the vrigl'it hand end yof the device. Then the roller carrying plate 8 is adjusted to the desired height as the lile or other sharpening medium is reciprocated across the roller 15 and engaged with the cutting edge of the blade in an obvious manner.

. It is thought that by considering the fore-v going description in connection with the drawings, a clear understanding of the construction and arrangement of parts as well as the method of use and advantages will be quite clear. In view of this, a more lengthy description Yis thought unnecessary.

Minor changes coming within the field of invention claimed may be resorted to if desired.

I claim: 1

1. As a new product of manufacturaa blade clamping device comprising a wooden backing block, a metal clamping plate and retaining means for said plate, together with an adjustably mounted roller supported on said block adjacent the top Vof the latter.

2. As a new product of manufacture, a

blade clarrnping; vise comprising a backing block, bolts Vcarried thereby, a clamping plate associated with one side ofthe block, retaining nuts for said plate, the opposite side of the block being cut away at its top to provide a clearance space, a roller mounted for rotation in said clearance space, and a support for said roller comprising a plate adjustabl mounted on the llast named side of saidbock. i y

3. In a Sharpener of theolass described, a backingmember of compressible material, blade clamping means on one side of the body and means on the opposite side of the body for aiding in the manipulation of a sharpening implement comprising an adjustably mounted plate, and a rest roller `blade clamping means -on one side of the block, a file rest and manipulating roller on the opposite siderof the block, and means for adjustably mounting said roller on said block.

In testimony whereof I aliix my si nat-ure.
