Improvements in or relating to Spanners. Wrenches, and
the like.
1, EDWARD WILLARS of Cropston in the county of Leicester Engineer, do hereby
declare the nature of this invention to be as follows:-
The object of this invention is to produce a spanner which may be conveniently
worked or used at different angles and which is specially adapted for use where the
nut to be operated upon is confined within very limited space.
To carry out my invention therefore I provide an iron or other suitable jaw of
convenient size and shape, at the back of which and rigidly secured in a horizontal
position to the said jaw is a suitable toothed disc, both being preferably made in one
piece or casting.
On the two sides of the said toothed disc and kept in the required position by
means of bolts or pins, are two suitably shaped link plates having one end secured to
the centre of the toothed dise the opposite end being fastened in a convenier position
in the handle or lever of the spanner.
The upper end of the said handle or lever may be suitably hollowed or recessed to
allow of the free movement of the combined toothed disc and jaw, the outside or
upper edges of the handle are left projecting, thus forming two teeth which may when
necessary engage with the teeth of the disc and produce rotary movement of the
combined toothed disc and jaw.
A modification of my invention may consist of a toothed wheel working within two
suitably shaped plates.
Passing through the toothed wheel and plates, may be a pin or spindle, which
projects a convenient distance below the plate and on which may be secured a circular
block, the end or flat portion being suitably recessed to receive square, hexagon or
other shaped nuts.

page_text: Also between the two plates, before mentioned, is a handle or lever suitably hollowed
and provided with teeth or projections capable of gearing into the toothed wheel and
rotating the circular recessed block as desired. The said handle or lever may be held
in position by means of a bolt and nut.
The pin or spindle already referred to may be made of such suitable length as to
allow the circular recessed block to engage with nuts not on a plane surface.
A suitable cottar will serve to hold the spindle and block rigidly.

Improvements in or relating to Spanners, Wrenches, and
the like.
I, EDWARD WILLARS, of Cropston, in the County of Leicester, Engineer, 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
siaiement :-
The object of this invention is to produce a spanner which may be conveniently
worked or used at different angles, and which is specially adapted for use where the
nui to be operated upon is confined within very limited space.
In the accompanying drawings, Figures 1 & 2 are side and edge views of my
improved spanner, shewing the jaw and handle connected by means of two outside
link plates.
Figures 5 and 6 are side and edge views of a similarly constructed spanner, but.
shewing the jaw and handle forked and connected by means of an internal
link plate.
Figures 3 and 4. are side and edge views of a modification of my invention.
In Figures 1, 2, 5 and 6, A is an iron, or other suitable jaw, of convenient size
and shape, at the back of which is a suitable toothed dise B, both being preferably
made in one piece or casting. On the two sides of the toothed disc B, and working
on a rivet or equivalent B at the centre of the disc, are two suitably shaped link
plates C, having their opposite ends pivotted in a convenient position to the handle or
lever D of the spanner.
The working end of the handle or lever D, may be suitably hollowed or recessed
to allow of its free movement when in a line with the links, over the combined toothed
disc Band jaw A, and the outer edges of the handle Dare left projecting, thus
forming two lips or pallets E, which when required engage with the teeth of the
disc
and produce rotary movement of the combined toothed disc and jaw.
It will be observed, that when the handle forms a continuation of a straight line
joining the pivots B' as shewn in the drawing, the toothed dise Bean be turned round
so as to place the jaw A at any working angle with the handle.
When the jaw A is fitted to the nut, and pressure put upon the handle, the latter
turns upon its pivot B until one of the lips E engage with the teeth of the disc, when
the parts become rigid and act like a solid spanner.
Figures 3 and 4. represent the application of my invention to a box spanner, and
show a toothed wheel F. working within two suitably shaped plates G. Passing
through the toothed wheel F, and plates G, may be a pin or spindle G, which projects
a convenient distance beyond the plate G, and on which may be secured a circular or
other shaped block H, the end or flat portion being suitably recessed at H to receive
square, hexagon, or other shaped nuts.

page_text: Also between the two plates G. is a handle or lever D. suitably hollowed and
provided with lips or projections E, capable of engaging with the toothed wheel F
and rotating the block H as desired.
The said handle or lever may be pivotted between the plates G by means of a bolt
or equivalent B. The spindle G may be made of such a suitable length as to allow
the block to engage with nuts not on a plain surface.
A suitable cotter or split pin I will serve to hold the spindle and block rigid.
It will of course be readily understood, that, I do not confine myself strictly to the
construction of spanners as shewn in the annexed drawings, as I may make numerous
modifications of the same without departing from the principle of my invention.
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 wrench or spanner, the combination with the jaw A having a toothed
extension such as B, of an independent handle or lever D, connected with A by one
or more links C, and having lips or projections such as E adapted to engage with the
toothed projection B, substantially in the manner and for the purpose described and
illustrated in Figures 1, 2, 5 and 6 of the accompanying drawings.
2. In a wrench or box spanner the combination with the jaw or head El carrying
a toothed wheel or pinion F which revolves with it, of an independent handle or
lever D connected with by one or more links G, and having lips or teeth E adapted
to engage with F, substantially as and for the purpose described and illustrated in
Figures 3 and 4 of the accompanying drawings.
