UNITED "STATES E. H. CAMP, OF JACKSON, MICHIGAN.

IIVIPROVED SHEAR AND STAKE HOLDER.

Specification forming part of Letters Patent No. 114,395, dated September 27, 1864K.

To @ZZ whom t may concern:

Be it known that I, E. H. CAMP, of Jackson, in the county of Jackson and State of Michigan, have invented a new and Improved Shear and Stake Holder; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying` drawing, formingy part of this speciiication, said drawing representing a perspective view of my improvement.

The object of this invention is to facilitate tinmen and all workmen in metals in adj usting the position, supporting, and holding of the shear-Shanks, stakes, and other tools.

The ordinary method of supporting and adjusting the said tools is to have a series of holes or cavities made in the upper surface of the work-bench. A special cavity is required for each different-sized shank, or for each different position in which the tool is to be placed. When the bench is too high or too low for the workman, it is necessary to alter the height of the bench.

By the use of my improvement the tinman is enabled to hold and adjust the position of shanks of the tools without having any cavities in the bench, and without changing the height thereof.

A is a base-plate, made of iron or other suitable material, to be securely fastened by any suitable means to the workmans bench. The 'central part of plate Ais hollowed out 0r made with a depression, as shown at a, to form a socket for the reception of a movable ball, B, of iron or other material. This ball contains a series of differentsized cavities, b, for the reception and holding of the shanks of different-sized shears, stakes, or other tools. The ball B maybe of -any suitable size, and may contain any suitable number of cavities. The

ball B is clamped and firmlyheld in any desired position by means of a clamping-plate,

c, by which it is hinged at d to lugs e, which rise from plate A, as shown. The front end of the plate C is pressed and fastened down by means of a vertical screw-rod, D, which passes up from the under side of plate A through an aperture in the front end of plate C, above which is a hand-screw nut, E, which engages the screw-'thread j on the upper end of rod D, as shown. The central part of plate C has an opening, g, the sides of which are beveled and form a socket for the reception of the upper part of ball B. By turning the nut E the plate C will be pressed down upon ball held in whatever position may be desired.

rlhe opening g in plate C permits the insertion of the tool-shank into the uppermost cavity of the ball B, and by adjusting the ball prior to clamping it the cavity may be so placed as -to give the tool and its shank such 'a position, either vertical or inclined7 as may be suitablefor the work to be done. The height of the tool may also be varied in the same manner to suit the workman.

I do not confine myself to the use of the screw-rod, nor to any particular form of device for locking or hinging the plates.

Having thus described myinvention, I claim as new and desire to secure by Letters Patentl. The employmentpof a ball shank-holder, operating in the manner and for the purpose herein shown and described.

2. The combination of the ball shank-holder with the plates A C, substantially in the manner herein shown and described.
