COMPLETE SPECIFICATION.
Improvements in or relating to Wrenches or Screw Keys.
I, IRA BURCH TRIPP, of 18 South Canal Street, Chicago, in the County of Cook
and State of Illinois, United States of America, Manufacturer, 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 relates to improvements in sliding jaw wrenches which shall be
simple and cheap in construction, and at the same time very powerful in operation
and easy of manipulation.
The invention also contemplates the combination of several wrenches of different
sizes and conformations, for instance with the preferred form of adjustable wrench "
there may be utilized a smaller nipple wrench and also an alligator wrench. Other
useful tools may further be combined with the improved wrench without affecting
its operation or inconveniencing the operator, for example, one of the extremities
of the wrench may be so formed into an effective screw driver as I shall describe.
In order to better understand the nature of the invention, attention is directed
to the accompanying drawings forming a part of this specification; and in
which:
Figure 1, is a side view of the device, the parts being assembled and shown as in
operation;
Figure 2, is a similar view, the parts being slightly separated, as when a nut
is being grasped; and,
Figure 3, is a section taken on the lines of Figure 1.
In all of the several views, like parts are indicated by the same numerais of
reference.
The entire device is made of metal, preferably of sheet steel stamped to the proper
shape. The body portion 1, of the wrench is provided with the fixed jaw 2, formed
integral with it at one extremity, and with the teeth or serrations 3 on one edge
extending from adjacent to the jaw to a point near the other extremity of the
body.
The sliding jaw 4 of the wrench is formed upon one end of the part 5, which is
provided with teeth 6, similar to the teeth 3. An operating lever 7, which is
constructed of a single sheet of metal bent upon itself to the shape shown, has
downwardly extending legs 8, which straddle the body 1, and are pivoted at 9 to
the sliding jaw 4.
The parts being placed in the position shown in Figure 2, can be adjusted upon
the nut, which will be firmly engaged between the jaws, the lever 7
being held in engagement with the body, as shown in Figure 1, to thereby retain
the teeth 3 and 6 tightly together. This takes place as a natural result of the
grasping of the wrench in the hand, and effectively locks the jaws.
In order to increase the utility of the device. It may grind the end of the part 5
down to a sharpened edge, forming a screw driver 10, which can very handily be
used when the part 5 is maintained in a position at right angles to the body 1,
or is removed therefrom.

page_text: An alligator wrench 11 may also be formed upon the extremity of the body 1.
By cutting away the body within the alligator wrench, a nipple wrench will be
formed, for turning nuts too small to be readily grasped by the jaws of the adjusting
wrench and which will further increase the utility of the device.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. In a sliding jaw wrench, the combination with the body having the fixed
jaw, and having one edge toothed or serrated, of a sliding jaw having similar
teeth adapted to engage with those in the body, and a locking lever carried on
the opposite side of the body from the sliding jaw, having legs straddling the said
body and pivoted to said sliding jaw, substantially as set forth.
.2. In a sliding jaw wrench, the combination with the body having the fixed jaw,
and having one edge toothed or serrated, of a sliding jaw having similar teeth
adapted to engage with those in the body, a locking lever carried on the opposite
side of the body from the sliding jaw, having legs straddling the said body and
pivoted to said sliding jaw, and a screw driver formed on one extremity of said
wrench, substantially as set forth.
3. In a sliding jaw wrench, the combination with the body having the fixed jaw,
and having one edge toothed or serrated, of a sliding jaw having similar teeth
adapted to engage with those in the body, a locking lever carried on the opposite
side of the body from the sliding jaw, having legs straddling the said body and
pivoted to said sliding jaw, and an alligator wrench formed on one extremity of
said wrench, substantially as set forth.
4. In a sliding jaw wrench, the combination with the body having the fixed
jaw, and having one edge toothed or serrated, of a sliding jaw having similar
teeth adapted to engage with those in the body, a locking lever carried on the
opposite side of the body from the sliding jaw, having legs straddling the said
body and pivoted to said sliding jaw, and a nipple wrench combined with an
alligator wrench on one extremity of said wrench, substantially as set forth.
5. In a sliding jaw wrench, the combination with the body having the fixed
jaw, and having one edge toothed or serrated, of a sliding jaw having similar teeth
adapted to engage with those in the body, a locking lever carried on the opposite
side of the body from the sliding jaw, having legs straddling the said body and
pivoted to said sliding jaw, and a screw driver formed upon one extremity of said
on another
wrench and a nipple wrench combined with an alligator wrench
extremity of said wrench, substantially as set forth.
