BOLT-,CUTTER I SPECIFICATION forming' part of Letters Patent No. 672,869, dated April 23, 1901.

Application filed November 30, 1900. Serial No. 88,205. LNo model.)

To all whom it may concer-m Beit known thatl, SAMUEL S. BoLsrNGER, a citizen of the United States, residing at Brockway, in the county of Douglas and State of Oregon,have invented certain new and useful Improvements in Bolt-Cutters; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in bolt or rod cutters. It provides for readily and eectively severing the bolt or rod, as intimated, and for securing the proper application of the leverage or power to aid the cutting operation, while simplicity, cheapness, and reduced cost of manufacture are obtained.

It consists of the detailed construction, combination, and arrangement of the parts for accomplishing the above ends or objects, substantially as hereinafter more fully disclosed, and specically pointed out by the claims.

In the accompanying drawings, illustrating the preferred form of my invention, Figure 1 is a broken side elevation thereof, the jaws being shown open. Fig. 2 is a broken side View witha side plate, 85e., removed, the jaws being shown closed. Fig. 3 is an edge View of the invention.

Latitude is allowed herein as to details, as they may be changed or varied at will without departing from the spirit of my invention and the same yet remain intact and be protected.,

In carrying out myin vention I pivotbetween suitably connected or bolted together guideplates l l two jaws or cutters 2 2, preferably provided with removable cutters, which when the jaws are open are adapted to receive between them the 'bolt or rod to be cut, the lower opposed portions or edges of said jaws being rounded, as at 2b, the purpose of which will appear farther on.

The handles or levers 3 3 are each preferably in two parts, the outer end portions 3, constituting cams, eccentrically pivoted between the guide-plates l, with outer convexed or rounded edges 3b, adapted to engage the rounded edges 2l of the jaws or cutters 2, and

inner corresponding edges or faces 2c, adapted to roll or bear upon each other primarily to exert leverage or power upon and effect the opening and closing of the said cutters or jaws and to secure the maximum cutting action of the latter when first or initiall-y'engaging the bolt or rod to be cut when most required and incidentally to facilitate the movement of the parts, dispensing with cogs, &c., therebetween. The jaws or cutters be ing arranged laterally or outside of the camendportions of the handles or levers, it will be seen that the latter can be brought toward each other, thereby effecting the cutting action by said jaws or cutters with the minimum movement of the hand, consequently to the greatest advantage. This is apparent from the fact that such movement of said handles, whose cam ends engage the longer arms of the cutters or jaws -to bring the cutting edges of said cutters together, is eected by the contraction of the hand, as in grasping an article and in bringing the lingers toward the palm, as contradistinguished from the use of the hands in moving the handles or levers apart.

The jaws or cutters and handles are connected up or together by means of crossing links 4 to provide for holding them mutually in engagement as the handles are actuated, said links being slipped upon suitably headed bolts or studs 4i, secured or screwed to said jaws and handles, respectively, the bolts or studs connected to said jaws moving in arcuate or curved slots- 4b in one of the guideplates l to accommodate the movement of said jaws.

The handles or levers 3 each have their hand-grasping and cam-ended portions halved and toothed or cogged together, as at 5, with adjusting-bolts 5a passing therethrough, to provide for varying the angle of connection therebetween to accordingly accommodate the grasping off said handles in compensating for wear of the cutting edges or faces of the cutter or jaws.

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

1. A bolt or rod cutter, comprising jaws or cutters, handles or levers having outer end IOO cam portions adapted to engage said jaws, said jaws or cutters which pass through said 1o and crossing links connecting with said jaws slots, substantially as specified. and handles or levers, respectively, substan- In testimony whereof I aiiix my signature tially as set forth. in presence of two witnesses.

5 2. A bolt or rod cutter, comprisir, 0f jaws or cutters, guide-plates one having zltzuate or SAMUEL S BOLSINGER curved slots, handles or levers adapted to Witnesses: engage said jaws or cutters, and crossing E. H. LEMON, links, with the connections between them and 1 GEO. BYRON.
