BOLT-CUTTER.

Specification of Letters Patent.

Patented Sept. 26, 1905. l

Application led May 18,1905. Serial No. 261,003.

To @ZZ whom it may concern Be it known that I, FRANCOIS TESSIER, a subliect of King Edward VII, residing at Somerville, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Bolt-Cutters, of which the following is a specification.

The object of this invention is to provide a cheap, simple, and durable tool for cutting bolts, rivets, and the like.

The object of the invention is, further, to provide a tool of the character set forth which will have great power and which is adapted to be attached to the nut of a bolt in such a manner that the projecting end of 'said bolt may be cut off quickly and smoothly and flush with the top of said nut.

The object of the invention is, further, to provide a tool of the character set forth which may be conveniently applied to cut either from the right or left to accommodate the tool to use in various positions and under varying circumstances.

The invention consists in the combination and arrangement of parts set forth in the following specification, and particularly pointed out in the claims thereof.

Referring to the drawings, Figure l is a plan view of my improved bolt-cutter, showing the same with the handles in line with each other and with the cutter extending across the orifice in the position in which said cutter would be after the bolt or rivet had been severed. Fig. 2 is a plan view of the Same, illustrating the handles separated and one of said handles partly broken away, the cutter being in position ready to begin the cutting of the bolt, a nut and bolt being illustrated in position for said bolt to be severed, said bolt being illustrated as attached to a portion of the felly of a wheel. Fig. 3 is an enlarged section taken on line 3 3 of Fig. 2, illustrating the cutter in position to begin cutting the end of the bolt, which extends beyond the top of the nut. Fig. 4 is an enlarged section taken on line 4 4 of Fig. l, illustrating the cutter in position after the end of the bolt has been severed, the bolt being illustrated as attached to the felly of a wheel.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 8 is a holder, formed, preferably, of a piece of flat steel, one end of which is enlarged and provided with an orifice 9, extending therethrough. A pivotal Stud 10 is fastened to the holder 8, and to Said stud is pivoted a lever 11. The holder 8 and lever 1l are extended at one side of the pivotal stud 10 to form handles 12 and 13, respectively. The holder 8 is extended upon the opposite side of the pivotal stud 10 from that upon which the handle 12 is located and has formed therein, as hereinbefore set forth, the orifice 9, and between said orifice 9 and pivot 10 is a stud 14, fast to the holder 8 and projecting therefrom through a slot l5, formed in a cutter 16, said cutter being held upon said stud by means of a nut 17 and washer 18.

rIhe cutter 16 is provided at one end with a cutting edge 19 and at the opposite end thereof is pivotally connected by a stud 2O to the lever 11 at the opposite side of the pivot 10 from that upon which the handle 13 of said lever is located. erabiy formed upon a curve.

The operation of my improved bolt-cutter is illustrated in one of its adaptations in Figs. 2 to 4, inclusive, in which a bolt 21 is fastened to a felly 22 by a nut 23 and washer 24. The'nut 23 iits in the rectangular oriiice 9, and the holder 8 is of the same thickness as Said nut at that portion thereof containing the orifice 9, so that the upper surface of the holder 8 is flush with the Lipper surface of the nut 23. Assuming the parts, then, to be in the position illustrated in Fig. 2, the handle 13 of the lever 11 is rocked in the direction of the arrow in Said figure until Said handle is in alinement with the handle 12 of the holder 8, or substantially in the position illustrated in Fig. 1. During this rocking movement it will be seen that the cutter 16 will be rocked upon the Stud 14 and at the same time will be moved longitudinally of the holder 8, so that a combined reciprocatory and rocking movement is imparted to the cutter by the rocking of the lever 11, and as this movement is imparted to said cutter the same will be forced transversely across the top of the nut 23 and across the bolt 21 with a shearing cut, great power being obtained by reason of Said shearing movement and also by reason of the fact that the cutter and lever form a toggle, so that by a slight expenditure of power applied to the handles 12 and 13 a very great cutting or shearing power will be imparted to the cutting edge 19 of the cutter 16.

By practical use it has been found that a cutting-tool constructed in accordance with my invention possesses such power and holds the bolt so securely by means of the nut upon said bolt that the end of the bolt is Severed The cutting edge 19 is pref- 4 IOO IIO

with very little expenditure of power and leaves a very clean smooth cut, so that the end of the bolt is left with a surface free from any projections or roughness, the same appearing as if it had been filed or polished.

A great advantage of the tool hereinbefore described consists in the fact that the same may be placed in a variety of different positions and operated without ditlieulty, as the handle 12 may be moved to operate the cutter 16 from either side of the. holder 8, so that the bolt may be cut either from the right or from the left, as may be desired.

Having thus described my invention, what I claim, and desire by Letters Patent to secure, 1s

l. A bolt-cutter comprising in its construction a holder provided with an orifice adapted to receive a bolt, a lever pivoted to said hold er, and a cutter pivotally connected to said lever and slidably and rotatably mounted upon said holder, whereby said cutter may be moved across said orifice, both longitudinally and transversely thereof.

2. A bolt-cutter comprising in its construction a holder, a pivot fast to said holder, a lever journaled to rock upon said pivot, said holder and lever extended at one side ot' said pivot to form handles, said holder extended on the opposite side of said pivot from said lever and provided with an orifice therein, said cutter provided with a slot extending longitudinally thereof and havingits cutting' edge extending across said orilice, and a stud fast to said holder between said orifice andfpivot and projecting into said slot, said cutter pivotally connected to said lever, whereby a combined rocking and reciprocatory motion may beimparted by said lever to said cutter.

3. A bolt-cutter comprising in its construction a holder, a pivot fast to said holder, a lever journaled to rock upon said pivot, said holder and lever extended at one side of said pivot to form handles, said handles movable laterally across each other, said `holder extended on the opposite side of said pivot Ifrom said lever and provided with an orificetherein, said. cutter provided with a slot extending longitudinally thereof and having its cutting edge extending across said orifice,.and a stud fast to said holder between said orifice and pivot and projecting into said slot, said cutter pivotally connected to said lever, whereby a combined rocking and reeiprocatory motion may be imparted by said rlever to said cutterand said handles may be moved to impart a simultaneous forward andright or left hand movement to said cutter.

In testimony whereof fhave hereunto set my hand in presence of two subscribing witnesses.

FRANCOIS TESSIER.
