COMBINED HOLDER A ND GUIDE FOR SHARPENING SHEARS OR OTHER EDGED TOOLS.

SPECIFICATION forming part of Letters Patent No. 794,797, dated July 18, 1905.

Application filed November 16, 1904. Serial No- 233,028.

To all whom it may concern:

Be it known that I, PETER HAwKINsoN, a citizen of the United States, residing at the Astoria Hotel, Astoria, in the county of Olat sop and State of Oregon, have invented a new and useful Combined Holder and Guide for Sharpening Shears or other Edged Tools, of which the following is a specification.

This invention relates to a combined holder and guide for sharpening shears, knives, and other edged tools, and has for its object to provide a simple, inexpensive, and efiicient device of this character by means of which the shears may be conveniently supported while filing or otherwise sharpening the cutting edges thereof.

A further object of the invention is to provide means for supporting the file or sharpening-stone at the proper angle or inclination with respect to the holder, so as to give the desired bevel to the cutting edges of the shears.

A still further object is to provide means for supporting the point of the shears between the clamping-jaws of the holder, thereby preventing accidental displacement of the shearpart of this specification, Figure 1 is a perspective view of a combined holder and guide constructed in accordance with my invention, showing the manner of using the same. Fig. 2 is a transverse sectional view on the line 2 2 of Fig. 1. Fig. 3 is a transverse section on the line 3 3 of Fig. 1. Fig. 4: is a detail perspective view of the guiding member detached. Fig. 5 is a perspective view illustrating a modified form of the invention.

Similar numerals of reference indicate corresponding parts in allthe figures of the drawlngs.

The device may be constructed of wood, metal, or other suitable material, and consists of a pair of clamping members 5 and 6, provided with terminal handles 7 and having their opposite ends recessed, as indicated at 8, for the reception of the intersecting blades of the shears 9. The clamping members 5 and 6 are connected by a bolt or pin 10, which passes through the recess 8 and alined openings formed in the side walls of said members, attention being called to the fact that the members are spaced apart to accommo date the shear-blades and are free to move laterally on the pin or bolt, so that when inward pressure is exerted on the handles 7 the shears will be securely clamped between said members.

Extending transversely through the members 5 and 6 is a rod 11, provided with oppositely-disposed terminal eyes 12, and pivotally supported in said eyes is a rim or loop 13,adapted to be inserted under the point of the shearblade and prevent accidental displacement of 1 said blade during the sharpening operation.

As a means supporting the file or other sharpening-tool at the proper angle or inclination I provide a detachable guiding member 14, said member being preferably formed of a single piece of wire or other suitable material, one end of which passes through an elongated slot 15, extending transversely of the members 5 and 6, while the opposite end of the wire is bent to form'a plurality of coils or convolutions 16, upon which the end of the sharpening stone or file 17 is adapted to rest. The slot 15 is slightly inclined to correspond to the inclination or bevel of the cutting edge of the shear-blade, as best shown in Fig. 3,

,so that when the guiding member is reciprocated within the slot the stone 17 will engage the blade at the proper angle. By having the guiding member formed in the manner described the fingers may be readily inserted through the coils or convolutions 16, so as to permit the sharpening-stone to be readily grasped in the hand and a downward pressure exerted thereon in manipulating the same, while by means of the slot 15 the guiding member and stone may be moved longitudinally as well as transversely of the cutting-blade.

In operation the shears are clamped in position by introducing the pivotal point of said shears in the recess 8, with one of the cutting-blades thereof extending longitudinally between the members 5 and 6, as clearly shown in Fig. 1 of the drawings. The ring or loop 13 is then inserted under the point of the blade and an inward pressure exerted on the handles 7, thereby securely clamping the shears between the members 5 and 6, after which the guiding member is introduced in the slot 15'and said member and the sharpening-stone 17 reciprocated back and forth over cutting edge of the shear-blade. When one blade of the shears has been sharpened, the handles 7 are released and the opposite blade inserted between the clamping members and the operation above described repeated.

In Fig. 5 of the drawings I have illustrated a modified form of the device in which the detachable guiding member is dispensed with and a suitable guide-roller 18 substituted, said roller being supported at the proper angle or inclination and journaled on a bracket 19, secured in any suitable manner to the clamping member 6.

A removable clamping-ring 20 is also provided for supporting the point of the shearblade and holding the members 5 and 6 in engaging position.

From the foregoing description it will be seen that there is produced an extremely simple, inexpensive, and convenient device admirably adapted for the attainments of the ends in view.

Having thus described the invention, what is claimed is- 1. A device of the class described comprising a pair of clamping members adapted to receive a cutting -blade and each provided with a handle, and a tool-supporting guide member carried by said clamping members.

2. Adevice of the class described comprising a pair of clamping members adapted to receive a cutting-blade and each provided with a terminal handle, and atool-supporting guide member arranged at substantially right angles to the clamping members and carried by the latter.

3. A device of the class described comprising a pair of pivoted clamping members adapted to receive a cutting-blade and each provided with a handle, and a tool-supporting guide member mounted for reciprocationthrough said clamping members.

4:. A device of the class described comprising a pair of pivoted clamping members adapted to receive a cutting-blade, said members being provided with a transversely-disposed slot, and a tool-supporting guide member mounted for reciprocation in said slot.

5. A device of the class described comprising a pair of pivoted clamping members adapted to receive a cutting-blade and each-pro vided with a terminal handle, there being an inclined transversely-disposed slot formed in said members, and a tool-supporting guide nliember mounted for reciprocation in said s ot.

7 6. A device of the class described, comprising a clamping member adapted to receive a cutting blade and provided with a transversely-disposed slot, and a tool-supporting guide member mounted for reciprocation in said slot and provided with terminal coils or convolutions.

7 Adevice of the class described comprising a pair of pivoted clamping members adapted to receive acutting-blade, means carried by the clamping members for supporting the point of the blade between the same, and a tool supporting member mounted on said clamping members.

8. A device of the class described comprising a pair of spaced clamping-bars adapted to receive a cutting-blade, a loop or ring carried by the clamping-bars and adapted to-engage said blade, and a tool-supporting guide member mounted for reciprocation on the clamping-bars.

9. A device of the class described comprising a pair of spaced clamping-bars adapted to receive a cutting-blade, a loop or ring pivoted to the clamping-bars and adapted to engage the point of said blade, and a tool-supporting rod mounted for reciprocation on said clamping-bars and having one end thereof bent to form a plurality of convolutions or coils.

10. A device of the class described comprising a pair of spaced clamping-bars adapted to receive a cutting-blade, and each provided with a terminal recess and an intermediate transverse slot, a ring or loop pivoted to said bars and adapted to engage the point of the cutting-blade, and a detachable tool-supporting guide member mounted for reciprocation in said transverse slots.

11. A device of the class described comprising a pair of spaced clamping-bars adapted to receive a cutting-blade and each provided with a terminal recess and an intermediate transverse slot, a bolt passing through said terminal recesses and engaging said bars, and a detachable tool-supporting guide mounted for reciprocation in said transverse slots.

12. A device of the class described comprising a pair of spaced clamping-bars, adapted to receive a cutting-blade and provided with alined transversely-disposed inclined slots,and a tool-supporting guide member mounted for reciprocation in said slots.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.
