PRUNING IMPLEMENT.

SPECIFICATION forming part of Letters Patent No. 265,161, dated September 26, 188.,

- Application filed July 8, 1882. (ModeL) To all whom it may concern:

Be it known that I, FRANK O. SLANKER, of. Pomona, in the county of Los Angeles and State of California, have invented a new and Improved Pruning-Shears, of which the follow ing is a full, clear, and exact description.

In this improved arrangement of pruningsliears one of the shear-blades is attached to a lever which ranges along the lever of the other shear-blade, and is pivoted at the point of the blade to a lever, which is itself pivoted to the lever of said other shear-blade in about the position where shears are ordinarily pivoted, making an etlicient compound-lever arrangement, enabling the instrument to cut more powerfully than in the simple form.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate correspondingparts in both the figures.

Figure 1 is aperspective view of my improved pruningshears, and Fig. 2 is an end elevation.

A and B represent a pair of lever-handles, which are pivoted together at c, similarly to the manner in which pruning-shears are com; monly pivoted; but insteacbof attaching the) blades to them respectively, as in the common arrangement, I attach one, I), to lever A and the other, 61, to a lever, f, and pivot said lever ver B at g, arranging the lever f along lever A to bear against it at the end of its long arm, by which arrangementacompound leverage is obtainerhwhereby the blade cl is fulcrumed at the pivots c and g, and a sliding or slicing, as well as a direct cutting, movement is given to the blades, thus considerably increasing their operative capacity and facilitating the work. I also propose to arrange the elastic cushion it between the levers A and B at the point where they close against each other, to lessen the shock of the concussions thereat, said spring being fastened by a rivet, i, or other device, as preferred.

In practice the cutting-blades will be made separately from the levers and riveted on, as represented at j.

The usual spring, is, for opening the shears will be employed in these improved shears.

Shears constructed according to my invention may be readily ground without disconnecting the blades, the lever f being turned forward on the pivot g.

Having thus described my invention, I claim as new and desire to secure by Letters Paten t The combination, in pruning-shears, oflever f, having blade d, lever A, having blade I), with lever B,,said leverB being pivoted to lever A at c, and lever f being pivoted to lever B at g, substantially as described.
