in the county of Warren and State of Pennsylvania, have invented certain new and useful Improvements in Shears and Scissors Sharpeners, of which the following is a specificatlon.

My invention relates to an improvement in shears and scissors sharpeners; and the object is to provide a simple portable device of the character mentioned in which an oilstone or other sharpening medium may be held in connection with means for clamping and sliding the shears at the upper angle thereacross.

My invention further consists in certain novel features of construction and combinations of parts, which will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, F igurel is a view in perspective of my improved sharpener. Fig. 2 1s a transverse section through the clam Fig. 3 is a transverse section through t e base and rod 10, showing the post in elevation. Fig. 4 is a longitudinal vertical section through the post and swiveled bearing. Fig. 5 is a longitudinal section throu h the clamp, andFig. 6 shows a slightly-mo ified form of rod 10.

A represents the base of my improved shears and scissors shar ener, it being adapted to rest on a table or l iench and be conveniently screwed in position by means of fasteners 1 1.

The stone or othersharpening device 2 is held in position on the base, as shown in'Fig. 1, it beihg removable therefrom, preferably by moving it sidewise.

A hollow post Sis erected at one end of the base, and the shank 4 is su ported therein at such elevation as may be 'esired, the elevation being regulated by a thumb-screw 5 in the block 6 and a slot 7 being rovided for the thumb-screw to work up and down in.

The shank 4 is provided with a swiveled' bearing 8 at the upper end to project laterally thereover. This bearin is provided with a hole 9. A rod 10 is sli able back and forth and is held in the swiveled bearing, it being limited in its movements by the collars or One form of rod 10 is shown in Fi 1, and a slightly-modified form is illustrate in Fig. 6.

not wis The clamp is adjustably connected with 'the forward end of rod 10. This clamp consists of two jaws 12 and 13, and blade 14 of the shears or scissors is held between them by turnin the thumb-screw 15, a spring 16 normally orcing the plates or jaws of the clamp apart when the screw is reversed to admit of One of these jaws is bowed, as shown in Fi 5, through the center, so that they will 0 amp more securely when forced together by the thumb-screw 5. One jaw is also provided with lugs 20 20 at its end to keep the jaws parallel. These jaws are connected by the arm 17 with the end of rod 10, and then angle is regulated by the thumb-screw18, which connects the arm to the'rod adjustably. The opposite end of rod 10 serves as a'handle.

From the foregoing it will be seen that the exact angle of the sharpened edge of the blade may be provided for by the elevation of the shank 4 in the post 3 and by the inclination of'the clamp at the end of the rod when thus adjusted with the blade and clamped between the jaws. The operator simply gras s the handle end of rod 1(),re-

' ciprocates t e rod until the blade is sharpened, the sharpening medium 2 being used with oil, water, or dr The stone or sharp enin device 2 may li e removed or replaced by siding it laterally or lifting it from its seat. The entire article is simple and may be made at a comparatively small initial cost and is most effective in the performance-of its function.

Slight changes might beresorted to in the form and arrangement of the several parts described without'd'eparting from the s irit and sco e of my invention, and hence do sharpened and a reciprocating rod to whichthe clamp is connected, and adjustable supporting means with which the rod has sliding connection.

2. The combination with a sharpening mediiim, of a clamp for holding the article to be sharpened and a reci rocating rod to which the clamp is adjustab y connected, and vertito limit myself to theexact con-- cal adjustable support having a swiveled bearing through the'medium of which the rod has sliding connection.

.3. The combination with a base a sharpen- 5 ing device and a hollow post, ofa shank supgorted in the post, a block adjustable u and ort of the s ank,-

own in the post for the su p a bearnig swiveled to the shank, a rod having sliding connection through a hole in the bear- Io ing, and a clamp adjustably connected with the rod.

4. The combination with a sharpening device of a clam com rising two jaws, one of Y which is boWe len t wise, means for clamping the jaws upon t e blade to be sharpened, 15 and means for re lating and'definitely determining the ang e of the clamp.

In testimony whereof I afiix my signature in presence of two Witnesses.
