SPECIFICATION forming part of Letters Patent No. 280,825, dated July 10, 1883.

Application filed J nne 17, 1882. (No model.)

To all whom it may concern:

Be it known'that I, TIMO HY D. Horon- KISS, of Higganum, in the county of Middlesex and State of Connecticut, have invented a certain new and useful Improvement in Outting-Pliers, of which the following is a description, reference being had to the accompanying drawings, where Figurel is a side view. Fig. 2is a view similar to Fig. 1, with a side plate removed, so as to show what is behind it. Fig. 3 is a top view. Fig. 4 is a view in section on the plane as as.

My improvement mainly pertains to that class of cutting-pliers having two lever-handles with a short lever intermediate between them; and it consists in the combinations of parts set out in the claims at the end of this de scription. g r

The letter a denotes a lever-handle, the up per end of which carries one of the detachable cutters.

The letter 1) denotes a short lever pivoted to the lever-handle a, intermediate between that lever-handle and the other lever-handle, c. A short lever, 12, carries the other of the detachable cutters, and the spring d tends to press the levers a and b apart.

The letters 0 e denote two side plates, which are attached to the sides of the levers a and c, the latter being pivoted therein.

The short lever 12 has in what may be called its outer side a socket, b, for the reception of the rounded side of the rocking shaft f.

The lever-handle c has in what may be called its inner side a U-shaped socket, c, for the reception of the U-shaped side of the rocking shaft.

It isobvious that by pressing the lower ends of thetwo lever-handles together the two outters will be caused to meet, and that on releasing such pressure the spring will throw the two outters apart. The improvement in this regard consists in the use of the rocking shaft f as an intermediate between the short lever b and the lever 0, these two levers being appropriately socketed for shaft.

I am aware that the general combination of these three levers is old; but the particular combination by which the movements of the levers b and c are connected is new.

the reception of this rocking.

The letters 9 9 denote the detachable and interchangeable cutters. The heads of the levers a and b are furnished with the recess h,

having one side at a right angle to the bottom of the recess and the other side at an acute an gle to the bottom of the recess.

The screw i may be used to keep the cutters from accidental displacement.

I claim as my invention- 1. .In combination, the handle-lever a, the intermediate lever, I), having the socket b, the handle-lever 0, having the socketc, the rocking sha'ft f, and the side plates, 6 c, all sub I
