COMPLETE SPECIFICATION.
An Adjustable Combination Spanner and Pipe Wrench.
I, PERCIVAL HENRY PARKYN, of 158, Union Street, Plymouth, in the County
of Devon, Engineers' Fitter, 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 an improved tool adaptable for use as an adjustable
spanner for engaging with any size square or polgonal nut, and easily convertable
into an adjustable pipe-wrench.
In the accompanying drawings Figs. 1 and 2 are like side elevations of my
said improved tool, the former as it would appear when arranged for use as a
spanner, and the latter as it would appear when arranged for use as a
wrench, for engaging with and gripping a pipe or other cylindrical or circular
body.
From cast or wrought steel or other suitable metal or metals I produce my
improved tool, consisting of a body A, head B and handle C, preferably formed
integrally with each other. The said body portion is preferably rectangular in
cross section, but may be of any suitable shape that lends itself to the formation
of teeth D upon its upper or back surface, the head B being of any formation but
preferably that shewn, the inner face of which B may be plain, jagged, or
serrated as desired, but always at right angles to the plane of A.
The cross sectional dimensions of the handle C is less than that of the body A,
to permit an adjustable jaw E to be passed freely thereover the said jaw being
formed internally to fit and slide freely upon the body A, and provided at its
upper end with a worm wheel F, adapted to mesh with the teeth D of the body A
when rotated by the thumb and forefinger. The said jaw is formed to provide
at its lower end an extension G, one side of which G would at all times be parallel
with the face B of the head B, and provided with a like surface, while the other
is at a suitable angle (preferably 60° or thereabout) with the surface G¹, and
provided with notches or ratchet teeth G².
My said improved tool when used as a spanner would have the jaw E placed
in the position shown by Fig. 1, so as to be capable of grasping almost any size
nut, when adjusted by the mere rotation of the worm wheel F as illustrated by
Fig. 1, and when needed for use as a pipe or like wrench, the said worm wheel
may be rotated until the said jaw E is clear of the body A, when, if slid along_C
and reversed, and replaced with its worm wheel again in contact with the teeth D,
and its surface G2 facing the surface B₁ of B, the tool may then be used for grasp-
ing a pipe or other circular body as illustrated by Fig. 2.
The said combination tool may be made of any size suitable for the work for
which it is intended.
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) The adjustable combination spanner and pipe-wrench substantially as
herein described and shewn.

page_text: (2) The combination tool, consisting of a body A, with head B and handle C,
the said body having a toothed surface D, with which meshes the worm wheel F
of a reversable jaw E with extension G, the said extension having upon one side
a plane surface G¹, and upon the other a ratcheted surface G2 substantially as
described and shewn.
