IMPROVEMENT IN PRUNlNG-SHEARS.

Specification forming part of Letters Patent No. 160,392. dated March 2, 1875; application filed December 19, 1874.

To all whom it may concern:

Be it known that I, JEFFERSON CHASE, of Orange, Franklin county, Massachusetts, have invented certain Improvements in Pruning- Shears, of which the following is a specification:

My invention consists of improved pruningshears having peculiarly-shaped cuttin g-edges, hereinafter described, and a chisel-edge on the extremity and in the line of the handle or main half of the shears.

It will be seen that when a twig is inclosed between them, as shown in the drawing, any pressure upon the blades which forces-them together in the act of cutting such twig, will tend to force such twig inward toward the pivot or fulcrum of the blades.

The outer end of the blade A terminates in a chisel-edge, a, by means of which the small shoots which often spring from the trunk of a tree may be readily removed. For the re moval of shoots which are above the head of the user, the chisel a will be found of great
