\VILLIAM J. PULLIAM, OF CHICO, CALIFORNIA, AS SlGNOR QF ONE-HALF TO ALLEN HENRY AND A. M. BARLEY, BOTH OF SAME PLACE.

WRENCH.

EJPECIFIGATION forming part of Letters Patent No. 350,602, dated October 12, 1886.

Application filed March El, 1886.

To aZZ whom it may concern.-

Be it known that I, WILLIAM J. PULLIAM, of Chico, county of Butte, and State of California, have invented an Improvement in Wrenches; and I hereby declare the following to be a full, clear, and exact description thereof.

My in vention relates to the class of wrenches, and particularly to a new and useful wrench for adjusting the nuts on the teeth of thrash IO lug-cylinders.

My invention consists in a short stock for entering the cylinder, a handled shank pivoted in said stock and projecting outwardly between the cylinder-bars, a socketed piece or r jaw pivoted in the stock for engaging the not from within. gears by which the rotation of the shank is transmitted to thesocketed piece I or jaw, a clamp on the stock for engaging one of the cylinder-bars and holding the stock steady. and ajaw or holder on the shank for engaging the tooth and keeping it from turning, all of which I shall hereinafter fully describe.

The object of my invention is to provide a or loosening the nuts, by which the teeth of a thrashingcylinder are secured to the bars without having to reverse the cylinder.

Referring to the accompanying drawings,

Figure l is a perspective view of my wrench.

Fig. 2 is a View showing its application.

A is the stock, consisting of a short box small enough to enter between the bars of the cylinder. w

3 5 B is a shank having a handle, I), and pivoted in the stock, whereby it may be rotated. In the stock is also pivoted or journaled the nut-v engaging jaw, here shown as a socketed piece, 0, which lies parallel with the shank, as shown.

0 Upon the stem of this jaw G, and housed in the stock A, is a gear or pinion, 0, which engages with another gear or pinion, b,'upon the main shank B, whereby power is transmitted from said shank torotate the socketed piece 4 5 or jaw.

Upon the inner side or bottom of the stock A is a clamp-arm, D, havinga bent or hooked point, d. The clamp-arm is fixed by a small set-screw, d, and may be adjusted longitudi- "the teeth are secured.

of holes, (1", in its body, with any of which the set screw may engage.

Fitted loosely upon the shank B is a forked jaw orholder, E, fromthehub of which an arm,

6, extends toward. and is adapted to enter a socket or hole, a, in the stock A. g

The use of my wrench is seenin Fig. 2. F are the bars of a thrashing-cylinder. G are the teeth, the threaded shanks of which pass through the bars, and Hare the nuts by which WVith the ordinary wrench the operation of fitting and tightening up the teeth or of removing them is rather long and tedious. Thetooth is first put through its seat in the bar, and is then struck with a hammer to drive it home properly. Then the entire cylinder must be reversed or turned half-way around in order to permit the wrench to pass through and operate on the inside of the then opposite side of the cylinder, in order to adjust and tighten up the nut on the inwardly-projecting shank of the tooth. When this is completed, the cylinder must be turned forward again and the next tooth inserted, as before. In using my wrench this constant reversal of the cylinder is avoided, and the tooth may he fitted, driven in, and its nut adjusted and tightened up without moving the cylinder at all. As willbe seen, the stock of the wrench is passed through between the bars of the cyl- 8o inder, and its socketed piece or jaw O fits over the nut. The clamp-arm D then engages with its hooked or bent end'one of the bars, either above or below, according to the direction in which it is turned. This prevents the stock from moving, and by reason of the longitudinal adjustment of said clamp-arm it may be fitted to various cylinders having different spaces between their bars. The forked jaw or holder E slips up over the sides of the tooth 0 and prevents said tooth from turning, and saidjaw or holder is itself held firmly by the en gagementof its arm c with the hole' a in the stock. The sliding movement of the forked holder "enables it to be readily fitted and ad- 5 justed to various lengths and positions. Every part being now fixed the handle I) is turned, whereby rotation is imparted to the socketed piece or jaw G, and the nut is set up or loosened, as the case may be. It will thus be seen that I00 the tooth can be driven in and its nut set up without having to move the cylinder.

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

1. I11 a wrench for adjusting the nuts on the teeth of a thrashing-cylinder, the combination of the stock A, for entering the cylinder, the handled shank B, pivoted in the'stoek and extending outwardly between the cylinder-bars, the nut-engaging piece or jaw O, pivoted in the stock, the gears between said jaw and the shank B and housed in the stock, a clamp on the stock for engaging the bars of the cylinder and holding said stock steady, and a jaw on the shank B for engaging and holding the cylinder-tooth, substantially as described.

2. In a wrench for adjusting the nuts on the teeth of a thrashing-eylinder, the combination of the stock A, for entering the cylinder, the handled shank B, pivoted in the stock and extending outwardly between the cylinder-bars, the nut-engaging piece or jaw O, pivoted in the stock, gearing, between theshank and said jaw, and the longitudinally adjustable clamparl n D. secured to the stock for engaging the eylinderbars, substantially as and for the purpose herein described.

3. In awrench for adjusting the nuts on the teeth of a t-hrashing-eylinder, the combination of the stock A, having a socket or hole, a, the

handled shank B, pivoted in the stock, the nut-engaging piece or jaw G, p voted in the stock, gearing between said jaw and the shank B, and the adjustable forked jaw or holder E, fitted on the shank for engaging the cylindertooth, and having an arm, 6, entering the hole a in the stock, substantially as herein described.

4. A wrench for adjusting the nuts on the teeth of a thrashing-cylinder, comprising the stock A, for entering the cylinder, thehandled shank B. pivoted in the stock and extending outwardly between the cylinder-bars, the sock eted piece or jaw G, pivoted in the stock and engaging the nut from within, the pinions or gears b c in the stock and upon the shank B and jaw C, respectively, the longitudina lyadjustable clamp arm D on the stock for engaging the cylinder-bars, and the adjustable forked jaw or holder E on the shank B, for engaging the cylinder-tooth, and having an arm, 6, engaging a socket or hole in the stock, all arranged and adapted to operate substantially as herein described.

In witness whereof I have hereunto setmy hand.

WILLIAM J. PULLIAM.
