Improvements in or relating to Adjustable Spanners.
We LLEWLLEYN AUGUSTUS PARROCK of 18 Presbury Road Aston Birmingham
Mechanical Engineer and JAMES DIAMOND of 1 Buckingham Street Birmingham,
Licensed Victualler, do hereby declare the nature of our said invention to be as
follows:-
Our invention consists of improvements in or relating to adjustable spanners in
which a ready means of adjustment with a firm grip is effected and in a simple
and efficacious manner.
We will describe our invention thus :-
We employ a bar of metal angular in cross section and of a required strength to
withstand the strain it may receive. The edges of this bar are parallel and at the
upper end is the fixed jaw which is part of same the lower end serving as the handle.
The second part or jaw is provided with a slot and is moveable on the first named.
The one side (the inner side) is formed as a jaw, and this corresponds with the
jaw first named. The outer side has an extension piece which is slotted and
receives a lever of the length or nearly so of the part termed the handle working
upon a pin and admits of being moved to and from the handle the end of this
lever is provided with a knob and at a required distance from the joint and upon
the lever is a boss and between the joint and the boss this lever is pivotted or
swivelled and this admits of a rotatory motion being given to the lever by means
of the knob.
To practically illustrate the same :-
The angular and parallel bar of metal with the fixed jaw has its outer edge
formed as a screw or thread and the boss upon the lever is screwed or threaded
correspondingly, and engages with the said screwed edge; a rotary motion is given
in the right direction by the swivelled part and by this means opens the jaws to
receive the nut or bolt or whatever purpose it may be required for, the motion
reversed brings the two jaws upon its work; it will be perceived that by this
means the jaws are controlled to the fraction and when the lever is brought down
with pressure the screwed boss engages with the screwed edge and is immoveable
until the pressure is released.
For a quick action or opening of the jaws the lever is brought away that is the
screwed boss is released from the screwed edge and slides down.
We form these spanners in any convenient way by stamping or casting and of
any suitable metal,

Mechanical Engineer, and JAMES DIAMOND of 1 Buckingham Street, Birmingham
Licensed Victualler, do hereby declare the nature of our said invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:
Our invention consists of improvements in or relating to adjustable spanners in
'which a ready means of adjustment with a firm grip is effected and in a simple
and efficacious manner,
We will describe our invention thus
We employ a bar of metal angular in cross-section and of a required strength
to withstand the strain it may receive. The edges of this bar are parallel and at
the upper end is the fixed jaw, which is part of same, the lower end serving as the
handle. The second part or jaw is provided with a slot and is moveable on
the first named. The one side (the inner side) is formed as a jaw, and this
corresponds with the jaw first named. The outer side has an extension piece
which is slotted and receives a lever of the heigth or nearly so of the part
termed the handle working upon a pin and admits of being moved to and from the
handle, the end of this lever is provided with a knob, and at a required distance
from the joint and upon the lever is a boss, and between the joint and the boss,
tbis lever is pivotted or swivelled and this admits of rotatory motion being given
to the lever by means of the 'knob.
To practically illustrate the same:
The angular and parallel bar of metal with the fixed jaw has its outer edge
formed as a screw or thread, and the boss upon the lever is screwed or threaded
correspondingly and engages with the said screwed edge a rotary motion is given
in the right direction by the swivelled part and by this means opens the jaws to
receive the nut or bolt or whatever purpose it may be required for, the motion
reversed brings the two jaws upon its work, it will be perceived that by this
means the jaws are controlled to the fraction, and when the lever is brought
down with pressure the screwed boss engages with the screwed edge and is
immoveable until the pressure is released.
For a quick action or opening of the jaws the lever is brought away that is the
screwed boss is released from the screwed edge and slides down.
We form these spanners in any convenient way, by stamping or casting and of
any suitable metal.
And in order that our invention may be clearly understood and more readily
carried into practice we have appended hereto a sheet of drawings upon which we
have fully illustrated the nature of the said improvements together with the mode
of, and means for carrying the same into effect.
Figures 1, 2, 3, 4 are longitudinal views of parts detached, but when put
together as shewn at Fig. 5, shews an adjustable spanner, constructed according to
our invention.
Figure 6, is a longitudinal view (substantially the same as Fig. 5 with a
modification of an adjustable spauner) constructed according to our invention.
Figure 7 is a longitudinal view (substantially the same as Figs. 5 and 6, with a
modification, of an adjustable spanner constructed according to our invention.
The same letters of reference indicate like or corresponding parts in each of the
figures where they occur.
a is the bar of metal, hollowed out at a' for lightness, the edges b. b. are parallel,
the fixed jaw is formed upon one end and is a part of a, the other end of a,
serving as the handle, the second jaw d is moveable by the slot or aperture e which

page_text: slides upon the bar b. shewn by dotted lines, and detached Figure 2, and in
application in Figures 5, 6. 7. d' is the inner side of the jaw corresponding to
the fixed jaw. is an extension piece which is slotted on its edge sufficient to
receive the form g, and which is provided with the hole f, the slot in the extension.
piece allows the form g to pass until the hole gland the hole fare opposite to each
other and a pin his passed through and rivetted over, i is a second hole in g, which
is provided with a recess into which the projection is placed being at the one end
of the lever while the other end of lever has & milled knob, the neck k coming
opposite to the hole i, this will admit of the pin 1, Fig. 5, or small screw being
engaged therein. The neck k, and the pin 4 allows the lever j to be moved to and
fro from the bar or handle a. In each of the Figures 1, 5, 6, 7, the bar a is screwed
or threaded on its edge at m, and in Figures 4, 5, 6, we shew a boss or wheel on
the end of marked n, which is serewed or threaded correspondingly to n.
In Figure 6 we shew a modification of Fig. 5 by which we gain great freedom in
the movement of, we still use the extension piece f, but this we form interiorly as
a socket to receive a ball which is at the end of marked o, this is known as a
ball joint or ball and socket.
In Figure 7, we dispense with the screwed boss and make the end of lever j¹
serrated as o² to engage with m, of a. p, is a lamina spring bent round a. secured by
the pin q, it is bowed at the top r, to receive the lever . When the lever j
assumes the position shewn in Figs. 6 and 7, that is away from the spring p, the
screwed or serrated parts are disengaged and by means of the lever the moveable
jaw d can be moved along a with the greatest ease, nearer to or farther from the
fixed jaw c, when the lever jl is brought down into the spring p, as Fig. 5 the
screwed boss or wheel n is brought to engage with m, and by giving a rotary
motion to by motion is given to d longitudinally and the two jaws c and d
are brought together to effect their purpose. Although this plan is not 80
expeditious as the first named it is very precise in its operation.
Figure 7 in its application has to be gripped continuously by the hand. In either
case the action reversed releases and opens the jaws.
We construct these adjustable spanners by stamping, casting or in any manner
suitable to our purpose.
While we have described the features of our invention, and the object we have
attained and shewn on the sheet of drawings, we do not limit ourselves to these
drawings only as illustrative of our invention, nor to the form or details of
construction but contemplate necessary or desirable changes in the construction
and the substitution of equivalent members (for instance we may arrange the
moveable jaw d with an aperture upon its upper edge sufficient to receive therein
the threaded boss or wheel the end of the lever with its parts working in one part,
which forms the aperture, while the other part is slotted to allow the lever to fall
to the handle as before set forth) without departing essentially from the
principle of our said invention.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is -
Improvements in or relating to adjustable spanners.
