Patented. Feb.
N. PETERS. PHOTO-UT U ITED STATES PATENT OFFICE,
JOHN RILEY, OF BOSTON, MASSACHUSETTS.
IMPROVEMENT IN WRENCHES'.
Specification forming part of Letters Patent No. 174,155, dated February 29, 1876; applica ion filed January 31, 1876.
To all whom it may concern:
Be it known that I, JOHN RILEY, of Boston, in the county of Suffolk and State of Massachusetts, have invented an Improved. Adjustable Wrench, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings making part of this specification, in which- Figure 1 is a perspective view of a wrench constructed in accordance with my invention. Fig. 2 is a perspective view of the same, the adjustable jaw being removed. Fig. 3 is a perspective view of the adjustable jaw. Fig. 4is a transverse section through both jaws and, the portion of the wrench between them.
In many positions where it is desired to tighten or loosen a nut, there is not suflicient space to applyand turn a monkey-wrench, and even it another description of wrench could be used, it is not capable of being ad justed to nuts of different sizes, rendering it oftentimes necessary to employ several wrenches for difl'erent-sized nuts. To supply the above-mentioned need is the object of my invention, which consists in a rod or shank having a handle and provided with a stationary jaw, and a portion having a screw-thread for a movable jaw to turn on, the latter being, clamped when adjusted in place by a binding screw a wrench so constructed being suitable for use and readily adjusted to nuts of different sizes located in positions difficult of access, where ordinary adjustable wrenches cannot be employed to advantage.
'To enable others skilled in the art to underderstand and use my invention, I will proceed to describe the manner in which I have carried it out.
In the said drawings, A represents a cylindrical rod or shank, provided at one extremity with a cross-bar, a, at right angles. thereto, which serves as a handle. The opposite extremity of the rod or shank A is provided with a stationary jaw, b, which is at right angles to the rod A, and also to its handle a.
A portion, 0, provided with a screw-thread, projects out at right angles from the shank A at the end provided with the stationary jaw b,
the screw portion 0 being also at right angles thereto. Over the screw portion 0 turns a movable jaw, d, which may thus be moved.
toward or away from the jaw 12, in order that the wrench may be adapted for nuts of different sizes; this jaw (I, when adjusted, being held rigidly in place by a clamping-screw, e, which passes through the head of the jaw 01,
and bears against a flattened side, h, of the cally, or nearly so, and where the ordinary wrenches are not adapted for turning the not on account of the handle coming into contact with the bowl.
Instead of the screw 0,, any other suitable clamping device may be employed.
The relative direction of the stationary jaw with respect to the shank a may be changed if desired; for instance, it may project out in line therewith and form a continuation thereof, or it may be situated on the other side of the shank and form a right or other angletherewith, in which case the position of the screw portion 0 must be made to correspond therewith- What I claim as my invention, and desire to secure by Letters Patent, is-
The shank A, with its stationary jaw b and screw portion 0, in combination with the movable jaw cl and a clamping device, substantially as and for the purpose described.
Witness my hand this 24th day of J annary, A. D. 1876.
JOHN RILEY. In presence of- N. W. STEARNS, P. E. TEsoHEMAoHER.
