To (/.ZZ fra/icm z5 'may concern:

Be it known' that l, HUGH S. 1Winn, of Clarksburg, county of Harrison, and State of West Virginia, a citizen of the United States, have invented certain new and useful Improvements in Ratchet Hydrant lVrenches, or" which the following 1s a specification.

My invention relates to an improvement in hydrant wrenches.

The object is to provide a simple tool adapted for use especially with hydrants.

This invention consists in the main of a handle fashioned at one end for coupling and uncoupling hose and having a section cut away at the opposite end and made re# movable therefrom, both main and removable section counterpart structures and adapted to be dove-tailed and mortised and tcnoned tog'ether and having orifices :formed therethrough and their inner faces counterbored and longitudinally grooved to receive a toothed wheel, having an opening through the center to receive a nut and a spring actuated ratchet plunger, fitted to and slidably mounted in thelongitudinal groove and adapted to cooperate with the toothed wheel.

In the accompanying drawings,

Figure 1 is an edge view.

Figure 2 is a view at right-angles to Figure 1 with the removable section removed.

Figure 3 is a view in perspective of the removable section.

Figure 4 is a section on line 4-4 of Figure l, and

Figure 5 is a section through the line 5 Vof Figure 2.

il represents the handle of the wrench with its end l, fashioned to receive and turn an ordinary hose coupling it having a hole 2, therein to receive the usual stud on the coupling.

The opposite end of the wrench is cut transversely and longitudinally through the center as indicated by the line 3, in Figure 1. and the numeral 4 indicates the removable section which is substantially a counters part of the integra-l half section 6, and the two are dove-tailed together at the inner end 7, as shown in Figures 1, 2 and 3 and otherwise fitted throughout their lengths on their inner faces as shown in Figure 1.

Each section 4 and 6 is provided with an orifice 8, vtherethrough andthe ends are counterbored or countersunk as shown at 9, to receive the ratchet toothed Wheel 10, the hubs ll, of which fit and turn in the oriices 8, as a bearing, the counterbore or countersinlr 9, affording clearance for the teeth of the wheel l0, as shown in Figures 1 and 2.

Fach section 4 and 6 is provided with a longitudinal groove 12, which when the parte are together is approximately square or rectangular in cross sect-ion and the ratchet plunger 13, is fitted to slide but excluded from turning therein. The tail 14, of this plunger is preferably of smaller diameter thus forming a shoulder 15, between which and the end 16, of the groove the spring 1T, is confined. rlhis spring normally forces the ratchet plunger against the teeth of the wheel 10, confining the movement of the wheel to one direction not turning the wheel when swung in the opposite direction. l'n other words, by reason of this construction the ratchet plunger rides over the teeth freely when the handle is turned one way and locks the handle to the wheel when turned in the opposite direction after the manner of other ratchet wrenches.

The angular slot 18, through the center is of any form, but as shown in Figure 2,

hexagonal.

The sections 4 and 6 are held together by dowel pins y19, projecting from the inner face of one section and entering dowel holes 20, in the other section, as well as by means of the dove-tailed inner ends 7, and by screws 21, which screw into the holes 22, threaded to receive them.

In this way .l have provided a simple ratchet hydrant wrench, composed of few parts, not easy to get out of order, but easily replaced if they do become impaired by simply unscrewing the screws 21, and separating the parts. The ratchet plunger, spring and toothed wheel are all shut in and housed and only the ends of the hubs 11, are exposed.

The hose coupling end forms an extension of the handle and increased leverage for the ratchet wrench end and by its curve indicates the direction in which the ratchet is to be turned and the ratchet wrench end constitutes an elongation of the handle and increased leverage for the hose coupling end, the whole presenting a neat and attractive appearance with a general taper throughout its length as shown 1n Figure l.

I claim,

A Wrench including a handle, having one end cnt out transverselyyand longitudinally through the center, and 'dove-tailed a't' the inner end, leaving an integral halfl sectioln;

removable counterpart half section having one beveled end Whlch lits thedove-tai-led nner end of the main section, each section having registering longitudinal grooves and count-ersunkv orifices, as Well as means for.
