SPECIFICATION forming part of Letters Patent No. 593,882, dated November 16, 1897.
' Application filed July 24, 1897. Serial No. 645,833 (No model.)
To all whom it may concern: I
Be it known that I, SAMUEL T; FREAS, a citizen of the United States,residing at'Trenton,
' 5 is a detail view, showing the oone'of the nut in the county of Mercer and State of New J er sey, have invented certain new and useful Improvements in \Vrenches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains tomake and use the same.
My present invention relates to an improvement in wrenchessuch, for instance, as bicycle-wrenches or other small-sized simple and convenient wrenches.
The object of the invention is to simplify and cheapen the construction-of wrenches of this character; and the invention therefore consists in the construction and combination of parts, substantially as will be described and claimed. 7
In the annexed drawings, Figure l is a side view of my improved wrench, partly broken away. Fig. 2 is a cross-section on line x as, Fig. 1. and the 'coacting parts. Fig. 4 is a detail View of a modification of the wrench. Fig.

4 A denotes the fixed jaw which is formed on the end of the handle B. The edge of handle 13 adjacent to the biting edge of jaw A is provided with a series of parallel inclined notches and ribs at, equivalent in arrangement to a section of a screw,-the same being engaged by the adjusting-nut.
The sliding or movable jaw O is formed integral with the sleeve or boxing'D, that e m- Fig. 3 is a view of the adj usting-nut' The sleeve or boxing D at a point adjacent to theseries of threads or ribs or is provided with a square-cut notch I), wherein is situated the adjusting nut or knurl E, having several screw-threads, preferably three,'as at e, which engage the handle-threads a, by which engagement the revolution of the adj usting-nut E serves to propel the sliding jaw toward or away from the fixed jaw. The nut E is furnished at one end with a projection or cone F, which loosely enters a correspondinglyshaped seat in the sliding jaw O. The opposite end of the nut E is fashioned with a depression or countersink. The adjacent end of the notch 19 formed by the projection G on the sleeve or boxing D is bored at g to receive a cup H, that is heldin the bored projection G by means of a pin 0. The end of the cup H nearest to the nut E is shaped to serve as a bearing for the single spherical ball I or pin that rests loosely between the aforesaid cup H and the countersink in the contiguous end of the nut. Within the hollow cup -H is a spiral spring J, tensioned against the ball I and causing the latter to press easily and constantly against the nut E.
As seen in Fig. 5, the cone F is formed with ratchetsor serrations K, which bite into the wall of the recess in the sliding jaw, or the ratchets or serrations may be formed in said recess, or said ratchets may be formed in both said recess or cone, as may be found most convenient or desirable. The object of these ratchets is to prevent the nut or knurl from rotating when pressure is exerted on the sliding jaw. The sliding jaw can be adjusted toward the fixed jaw by simplypushing it forward; but when an object is grasped between the jaws and pressure is exerted on the sliding jaw the ratchets will engage with each other, or the ratchets of the recess or cone, as the case may be, will bite into the adjoining part and thus prevent the nut from rotating.
Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
1 In a wrench, the combination of the fixed jaw, the sliding jaw, the adj usting-nut having a projection that enters the sliding jaw, and the ball-bearin g supportvfor the nut,
too
consisting of the removable cup in the end of the sliding jaw and a ball between said cup and the countersunk end of the nut, substantially as described.
2. In a wrench, the combination of the fixed jaw, the sliding jaw, the adjustingnut having a projection that enters the sliding jaw, and the ball-bearing support for the nut, consisting of the hollow removable cup in the sliding jaw, a ball between said cup and the nut, and a spiral spring within the cup bearing against the hall, substantially as described.
3. In a Wrench, the combination with a threaded handle carrying the fixed jaw, of r 5 of the nut, and the ball-bearing support for 20 the nut, substantially as described.
In testimony whereof I aflix my signature in presenceof two witnesses.
SAMUEL T. FREAS.
