I, WORTHWORKS WALL, of 36, Market Street, Bradford, in the County of York
Tailor do hereby declare the nature of this invention to be as follows:-
This invention relates to a simple form of spanner or wrench for the purpose of
adjusting bolts or nuts, which spanner is provided with a loose sliding jaw which can
be set to the required space without the employment of a screw.
To carry out my invention I form a jaw at the end of, and integral with the handle
of the spanner,
the inner surface of which jaw is at a right angle with the line of the
inner edge of the handle. The inner edge of the handle has teeth formed upon it
from the inside of the fixed jaw to the required distance along the handle, as far as
the loose jaw hereinafter described may be required to move.
The portion of the handle nearest to the fixed jaw and upon which the loose jaw
slides when being adjusted, is formed flat, having two parallel flat sides, and the
toothed edge before referred to.
The loose jaw has a rectangular slot formed in it, and inside the slot teeth are
formed at that end of the slot which is in contact with the teeth upon the inner edge
of the handle.
A lever is attached at a right angle to the loose jaw, and when the spanner
is in operation this lever lies close to the inner edge of the handle and is grasped
with it.
The other end of the slot presses upon and grips the back of the flat part of the
handle.
By opening the lever away from the handle the teeth in the slot of the loose jaw
are disengaged from the teeth on the inner side of the flat portion of the handle, and
when the jaw is adjusted to the required opening, by pressing in the lever to the
handle, the teeth are engaged and the loose jaw becomes firmly locked, the more
firmly the more pressure is applied to it.
Dated this First day of June 1887.

page_text: 1, WORTHWORKS WALL of 36 Market Street, Bradford in the County of York,
Tailor 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:—
This invention relates to a simple form of spanner or wrench for the purpose of
adjusting bolts or nuts, which spanner is provided with a loose sliding jaw which can
be set to the required space without the employment of a screw.
To carry out my invention I form a jaw at the end of, and integral with the handle
of the spanner, the inner surface of which jaw is at a right angle with the line of the
inner edge of the handle. The inner edge of the handle has teeth formed upon it,
from the inside of the fixed jaw to the required distance along the handle, as far as
the loose jaw hereinafter described may be required to move.
The portion of the handle nearest to the fixed jaw and upon which the loose jaw
slides when being adjusted, is formed flat, having two parallel,flat sides, and the toothed
edge before referred to.
The loose jaw has a rectangular slot formed in it, and inside the slot teeth are
formed at that end of the slot which is in contact with the teeth upon the inner edge
of the handle.
A lever is attached or formed at a right angle to the loose jaw, and when the
spanner is in operation this lever lies close to the inner edge of the handle and is
grasped with it.
The other end of the slot presses upon and grips the top of the flat part of the
handle.
By opening the lever away from the handle the teeth in the slot of the loose jaw
are disengaged from the teeth on the inner side of the flat portion of the handle, and
when the jaw is adjusted to the required opening by pressing in the lever to the
handle, the teeth are engaged and the loose jaw becomes firmly locked, the more
firmly the more pressure is applied to it.
In order to enable my invention to be fully understood, I will proceed to describe
the same with reference to the accompanying drawings in which Figure 1 represents
a side elevation of my improved spanner. Figure 2 represents a plan of the same.
Figure 3 represents a sectional elevation of the loose jaw and Figure 4 represents
a side elevation of my improved spanner having the handle strengthened at the
sides.
Similar letters refer to similar parts in all the Figures.
The fixed jaw is represented at A and the portion of the handle upon which the
loose jaw B slides is represented at C which portion of the handle has teeth D formed
on its inner edge, into which fit the teeth E formed at the end of the rectangular slot
in the loose jaw B.

page_text: By opening the lever F, formed or fixed to the loose jaw B, away from the handle
the teeth E become disengaged from the teeth D, on the inner side of the handle,
the loose jaw B is then adjusted to the required opening by pressing the lever F
to the handle, when the teeth become engaged and the loose jaw is firmly locked to
the handle.
The spanner represented at Figure 4 is formed wider at the part G of the handle
than at that part of the handle upon which the loose jaw B slides. In this case the
loose jaw is formed with an opening at the top of the slot for the purpose of placing
upon that part of the handle represented at C, when there the two sides of the slot
are connected by means of the pin or rivet H.
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 :-
The loose jaw B with the rectangular slot J in combination with the lever F to
which it is formed or fixed for the purpose substantially as described and represented
in the accompanying drawings.
