WILLIAM' DUNLOP, OF FULLARTON, CANADA.
IMPROVEMENT IN BOLT-TRIMMERS.
Specification forming part of Letters Patent No. 133,972, dated December 17, 1872.
V I To all whom it may concern:
' Be it known that I, WILLIAM DUNIQOP, of
Fullarton, in the county of Perth, Province of Ontario and Dominion of Canada, have invented a new and useful Improvement in Bolt- Trimmer, of which the following is a specification:
Figure 1 is a longitudinal section of my imf. j proved bolt-trimmer taken through the line a: m, Fig. 2, the/handles being broken off. Fig. 2 is a top view of the same.
Similar letters of reference indicate corre- "i sponding parts.
My invention is an improvement in the class of bolt-trimmers in which a cutting tool or chisel is reciprocated by arack-bar and toothed segment and it consists in the construction and arrangement of devices forming the complete or operative implement, as hereinafter described. a
A is the lower lever or handle of the implement, the forward end of which is made wide and has a slot formed in it to receive the operating parts of the device. B is a block, which slides back and forth upon ways a formed upon the lower parts of the inner surfaces of the side bars that form the slot, and which is held down to its place by stays 0 attached to the upper parts of the said surfaces. In a recess in the forward part of the lower side of the block B is secured, by a screw or bolt, a chisel, D, the lower side of which is flush with I the lower side of the handle or lever A. The
edge of the chisel D, when the block B is pushed forward, strikes against a steel cushion or plate, E, secured by a screw or bolt to the inner surface of the forward end of the the chisel D shaves off the projecting end of I the bolt. Upon the upper side of the rear part of the sliding block B are formed cogs or teeth 1), into which mesh the cogs or teeth f formed upon the rounded forward end of the upper lever or handle F. The forward end of the lever or handle F is pivoted by a bolt, G, to projections or lugs a formed upon the rear parts of the upper edges of the slotted forward end of the lower lever A, so that the sliding block B and chisel D may be drawn back by raising the free end of the lever F, and forced forward to make a cut by forcing the said end downward.
' Disclaiming the use in bolt-trimmers of a reciprocating-cutter, or cutter-bar, and a' toothed segment for operating the same- I do claim as new and of my invention- The improved implement herein described,
formed by the cutter D, the block or bar 13 provided with the teeth I), the slotted leverA having ways a and a downward projection at its front end, the cushion-plate E, stays G, and the lever F with a toothed segmental head fulcrumed at G, all constructed and arranged as and for the purpose specified.
