Improvements in Combination Wrenches.
A communication by HOWARD AFTAN POST and FRANK WILLIAM WRIGHT,
both of Wichita, in the County of Sedgwick and State of Kansas, United
States of America, Railway Postal Clerk and Railway Conductor respectively.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool and 6, Bank Street,
Manchester, both in the County of Lancaster and 323 High Holborn, in the
County of Middlesex, Civil Engineer do hereby declare the nature of this inven-
ion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
In the accompanying drawings, which consist of one sheet,
Figs. 1 and 2 are side views of the wrench, the one showing a slight modification
in the form of handle from that of the other;
Fig. 3, is a cross sectional view of the wrench, as shown in Fig. 1, on line 1-1
looking handleward ;
Fig. 4, a cross sectional view of the wrench, as shown in Fig. 2, on line 2-2
looking towards the sliding jaw; and
Fig. 5, is a detailed front view of a pipe cutting tool, such as is adapted for use
with the wrench for cutting off small pipes.
Referring to the drawings by letter, A, represents the fixed jaw, or head, of the
wrench. B. B. represents two parallel bars, arranged a little distance apart, and
fixed at one end, in jaw A, and at their opposite end portion they are connected
together. In Fig. 1, they are represented as terminating at said opposite end, in
sockets of a handle C, and in Fig. 2. as passing through a keeper D, and jointly,
forming the wrench handle, beyond said keeper, and at their connected end, the
metal thereof is flattened so that it may be easily and properly bent, and also so
that it may be broad enough, so that a hole may be made through it at the centre
of said bend.
E, represents the sliding jaw of the wrench, and is provided with two holes
through it, at right angle to its face, corresponding in diameter to that of bars B. B.,
and is sleeved on said bars, by placing the bars through said holes.
F, represents the adjusting screw of the wrench, and is arranged between
bars B. B. and is provided with a shank G, which extends, in Fig. 1, entirely
through the handle C, longitudinally, and in Fig. 2, through the keeper D, and
along between the handle portions of bars B. B. and thence through the hole of
the flattened bent connection of said handle parts, and is further provided at the
junction of said shank with an annular flange, or enlargement which bears against
the handle C, of Fig. 1, or the keeper D, of Fig. 2, and prevents the screw from
movement handleward. I, represents a knurled hand piece fixed upon the end of
shank G, at the handle end and serves as a means of turning the screw, and as a
means of preventing the screw from movement reverse to handleward, and is
provided with a series of peripheral sockets, or holes J, into which a lever may be
placed for turning the screw.
The screw thus arranged and provided is turned into a corresponding screw-
threaded hole of jaw E, which hole extends parallel with bars B. B., and, by
turning the screw, the said jaw is adjusted to or from jaw A, as may be desired.
The jaw faces are made parallel with each other, at one side of bars B. B., so
that they may be adjusted on nuts and other objects, and at the opposite side of
said bars they are made diverging, or what is commonly known as alligator form,
and one jaw is provided with teeth, of the form shown, so that the jaws, at that
ide, may be used for gripping and turning pipes.

page_text: Between the two bars B. B. the jaw faces are each slightly hollowed cross-wise,
as shown at K, and L, and provided in said hollows with cross teeth so that small
pipes may be entered between the jaws, between the said bars B. B. and gripped
as by a vice, by forcing jaw E, hard against it.
A pipe cutting tool, as shown at M, which may be provided with a frame adapted
to be seated against the face of jaw E, having a stem N, adapted to enter the screw
hole of said jaw, as represented in Fig. 1, may be used, seated as shown in Fig. 1.
for cutting off small pipes, and when the same is used, a curved plate O, is seated
against the face of jaw A, as shown in Fig. 1. against which a pipe may bear.
The wrench, thus made and equipped, is adapted as a combined nut wrench, pipe
wrench, vice grip pipe holder, and pipe cutter.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me by
my foreign correspondents, I declare that what I claim is:
1. The wrench described, consisting of the combination of the fixed jaw, the two
parallel bars, the handle fixed to or formed by said bars, the sliding jaw sleeved on
said bars, the adjusting screw turned into said sliding jaw, and provided with the
shouldered shank extending to the handle end, and the knurled hand piece fixed
upon said shank end, for turning the screw, in the manner substantially as and for
the purpose set forth.
2. The combination wrench described, consisting of the combination of the fixed
jaw provided with one square face and one diverging or bevelled face, and with a
toothed cross hollow between said faces; the two parallel bars, the handle fixed to, or
formed by, said bars, the sliding jaw provided with one square face, and one toothed,
diverging or bevelled face, and with a toothed cross hollow hetween said faces, the
adjusting screw turned into said sliding jaw, and provided with the shouldered
shank extending to the handle end; and the knurled hand piece fixed upon said
shank and provided with peripheral holes or sockets, substantially as and for the
☐ purpose specified.
3. In the combination wrench described, the combination therewith of the pipe
cutting tool M, and curved plate O, adapted to be seated respectively against the
face of jaws E, and A, and between the bars B. B. substantially as and for the
purpose specified.
