page_text: I, WILLIAM EDWARD PUGSLEY, of Lincoln, in the County of Lancaster, and
State of Nebraska, United States of America, Gentleman, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
My invention has for its object to provide a simple, strong and economical
wrench capable of ready adjustment to fit nuts and other devices of various
diameter.
To this end the said invention consists in certain peculiarities of construction and
combination of parts hereinafter described with reference to the accompanying
drawings and subsequently claimed.
In the drawings :
Fig. 1 represents a side elevation of my improved wrench partly broken away;
Fig. 2 a section of the same taken on line 2-2 of the preceding figure, and
Fig. 3 a perspective view of the lower wrench-jaw.
Referring by letter to the drawings, A represents a straight handle-bar of
suitable metal, having its forward end curved upon the under side and offset to.
form an abrupt shoulder b, this offset portion of the handle bar constituting the
lower jaw B of my improved wrench. Intermediate of its extremities the handle
bar A is provided with a concave socket for the half-round terminal c, of the
shank portion d, of an upper jaw C that is offset to form an abrupt shoulder e,
curved upon its upper side and transversely serrated upon its lower side. A pivot,
connects the half-round end of the upper jaw-shank with a clip D bolted or
otherwise rigidly secured to the handle-bar. Loose on the handle-bar and upper
jaw-shank is a collar E, and fast in this collar between said bar and shank is a
wedge-block F, the inclined face of the latter being uppermost. By a movement
of the collar the spread of the jaws B, C, is regulated and the forward movement
of said collar is limited by the shoulders b, e, of said shoulder.
The opposing faces of the upper jaw-shank and the collar E may be provided
with engaging serrations whereby they will automatically lock together and
prevent rear movement of said collar and wedge-block when the wrench is under
strain, and I may also employ a set screw G to positively lock the aforesaid_collar
and wedge-block in adjusted position. I also prefer to provide the lower jaw B with
longitudinal flutes as shown in Fig. 3 in order to improve the grip of the wrench.
From the foregoing description it will be seen that I provide a very simple
wrench having its greatest strength where it comes upon a nut, pipe or other device
to be turned the spread of the jaws to accommodate said wrench to devices of
varying diameter being easily effected by a movement of the collar having the
wedge-block fast therein.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. A wrench comprising a handle-bar having one end in the form of a jaw,
another jaw having a shank pivotally connected to the handle-bar, a collar loose on
the handle-bar and jaw-shank and a wedge-block fast in the collar between said
handle-bar and jaw-shank, substantially as set forth.
2. A wrench comprising a handle-bar having one end in the form of a jaw and

page_text: provided intermediate of its extremities with a concave socket, another jaw provided
with a shank having a half-round terminal engaging the handle-bar socket, a clip
fast on said handle-bar, a pivot connecting said jaw-shank terminal with the clip,
and a sliding device that regulates the speed of the jaws, substantially as set
forth.
3. A wrench comprising a handle-bar having one end in the form of a jaw,
another jaw having a shank pivotally connected to the handle-bar, a collar loose
on the bandle-bar and jaw-shank, a wedge-block fast in the collar between said
bandle-bar and jaw-shank and a set-screw for locking the collar in adjusted
position, substantially as set forth.
4. A wrench comprising a handle-bar having one end in the form of a jaw,
another jaw having a serrated shank pivotally connected to the handle-bar, a serrated
collar loose on the handle-bar and jaw-shank and a wedge-block fast in the collar
between said handle-bar and jaw-shank, substantially as set forth.
5. A wrench comprising a handle-bar having one end in the form of a jaw
provided upon its working face with longitudinal flutes, another jaw having a shank
pivotally connected to the handle-bar, a collar loose on the handle-bar and jaw-
shank and a wedge-block fast in the collar between said handle-bar and jaw-shank,
substantially as set forth.
6. A wrench comprising a handle-bar having one end in the form of a jaw
provided upon its working face with longitudinal flutes, another jaw having a
transversely serrated working face and a shank pivotally connected to the
handle-bar, a collar loose ou the handle-bar and jaw-shank, and a wedge-block
fast in the collar between said handle-bar and jaw-shank, substantially as set
forth.
