IMPROVEMENT IN BOLT-TRIMMERS.

Specification forming part of Letters Patent N0. l57,610, datcd Dccember 8, 1874; application tiled October 27, 1874.

To all whom it may concern:

Be it known that I, J. D. KING, of Fort Wayne, in the county of Allen and in the State of Indiana, have invented certain new and useful Improvements in Bolt-Trimmers5 and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon, making a part of this specification.

The nature of my invention consists in the construction and arrangement of a bolt cutter or trimmer, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, 1 will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure l is a plan view of my bolt-trimmer. Fig. 2 is an end view of the same. Fig. 3 is a cross-section through the. line so :10, Fig. 1; and Fig. 4 is aperspective view of one of the cutting-levers.

A A represent two plates, between which the operating-levers are pivoted. At one end of the plate A are secured two short posts, I) 1), upon each of which is placed a lever, B. The outer end of said lever forms a socket, O, for the reception of the tenon d of the knife or cutter D, said tenon being fastened in said socket by means of a set-screw, a. The inner end of each lever B is formed with two or more cogs, w, as shown. At the other end of the plate A are also two posts, 1), upon which are placed two levers, G G, having handles H H attached on their outer ends. The inner ends of these levers Gr are formed with cogs 3 that mesh with the cogs a; on the ends of the levers B. The posts I) are formed with screws 2' upon their outer ends, on which the plate A is placed and fastened by means of nuts h on said screws. Each lever G is on its inner side, at a suitable point, provided with a projection, m, which strike each other and form stops for the inward movement of the levers.

The cutters D can readily be removed and others substituted, when desired or necessary, or for sharpening.

The plates A A may be provided with holes of any suitable shape as ornaments, and to lessen the weight of the instrument.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

The pivoted cog-levers B B, sockets O G, cutters I) D, with tenons d, and the set-screw a, in combination with the plates A A and the pivoted eogged levers G G, all substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 3d day of October, 1874:. 1

v JACOB D. KING.
