Improvements in Spanners, Wrenches, and the like.
1, CECIL WAGENER HOLMES of The Leicester Cycle Works, Friday Street,
Leicester, Cycle Manufacturer do hereby declare the nature of this invention to
be as follows:-
-
This invention relates to spanners, wrenches and the like with one movable jaw
and is particularly designed to produce a strong yet light and serviceable spanner
which may be easily carried by the cyclist in his pocket or pouch.
In carrying out this invention I provide a bar having one jaw fixed upon or
integral with it; the jaw edge of this bar is flat and may be perpendicular or
otherwise to the face of the fixed jaw. The back of the bar I prefer to make not
quite parallel with the jaw edge so that the bar thickens as it recedes from the
fixed jaw.
At the end remote from the fixed jaw I may form in the end of the bar a
hexagonal recess to serve as a box spanner and may so arrange this as to receive
boxes of different sizes if desired.
The sliding jaw is made to slide upon the bar the slot being longer than the
breadth of the bar so as to provide room for a tapered gib having end flanges to
prevent it from slipping out from the movable jaw. The movable jaw on its back
end is provided with a set screw or equivalent tightening device préferably provided
with a milled or wing head.
To use this spanner the set screw or equivalent is slackened and the movable
jaw moved to the proper position and tightened up by the set screw forcing the gib
against the back of the bar.
The bar and jaws may be reduced in thickness for the sake of lightness so as to
leave preferably only a thin web in the centre. A screw driver extension or
attachment may be provided where required.

COMPLETE SPECIFICATION.
Improvements in Spanners, Wrenches, and the like.
I, CECIL WAGENER HOLMES of The Leicester Cycle Works, Friday Street,
Leicester, Cycle Manufacturer, 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 spanners, wrenches and the like with one movable jaw
and is particularly designed to produce a strong yet light and serviceable spanner
which may be easily carried by the cyclist in his pocket or pouch.
The invention will be best understood by reference to the accompanying drawings
n which :-
Figure 1 is an elevation, with the adjustable jaw shown partly in section, of a
panner constructed according to my invention and
Figures 2 and 3 are perspective views of the adjustable jaw and the gib
respectively, detached from the non-adjustable part of the device.
Like letters indicate like parts throughout the drawings.

I provide a bar A having one jaw A' fixed upon or integral with it; the jaw
edge A³ of this bar A is flat and may be perpendicular or otherwise to the face
of the fixed jaw A'. The back As of the bar A I prefer to make not quite
parallel with the jaw edge A³ so that the bar thickens as it recedes from the fixed
jaw A¹
At the end remote from the fixed jaw A¹ I may form in the end of the bar a
hexagonal recess or aperture A' to serve as a box spanner and may so arrange this
as to receive boxes not shown in the drawings of different sizes if desired.
The adjustable jaw B is made to slide upon the bar A the slot B' Figure 2
thereof being deeper than the breadth of the bar A so as to provide room for a
tapered gib C having end flanges C1 C2 to prevent it from slipping out from the
movable jaw B. The movable jaw B on its back end is provided with a set screw
or equivalent tightening device D preferably provided with a milled or wing
head D'.
The flange C¹ at one end of the gib C extends around three sides of C and the
flange Cat the other end projects only from one side so as to enable the gib C to
be passed easily through the slot B¹ before the adjustable jaw B is placed on the
bar A, for which latter purpose the slot B' is sufficiently deep to pass over the
non-adjustable jaw A'; or the reverse of this arrangement may be provided,
viz. the flange C2 may extend around three sides and the flange C¹ project from
one side only.
The adjustable jaw B is preferably cranked in the manner shown whereby the
sloping back A need not be carried so far back as would be necessary if the jaw
were straight and so as to obtain with the minimum of weight an extended bearing
for the jaw upon the bar A.
To use this spanner the set screw or equivalent adjusting device D is slackened
and the movable jaw B moved to the proper position on the bar A and tightened
thereon by the set screw D forcing the gib C against the back A³ of the bar A.
The bar A as at A' and jaws may be reduced in thickness for the sake of
lightness so as to leave preferably only a thin web in the centre. A screw driver
extension or attachment not shown in the drawings may be provided where
required.
As shown in Figure 1 the back A³ is shown inclined towards the axis of the bar
and the face A parallel thereto but this arrangement may if desired be reversed.
When using the spanner the tendency is to force the movable jaw B on to the
wider part of the bar A so that the greater the power applied to it the more
firmly will the jaw B be held on the bar.
It will readily be seen that instead of using a screw D as the means for adjusting
or tightening the movable jaw B another device may be employed in combination
with the inclined face for effecting the same result.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
:-
1. In an adjustable spanner or the like the combination with a bar having two
jaws one fixed and the other movable thereon of an inclined part such as A
substantially as and for the purpose described and illustrated in the accompanying
drawings.
2. In an adjustable spanner or the like comprising a bar having two jaws one
fixed and the other movable thereon the combination with the movable jaw of a
gib such as C and set screw or tightening device such as D substantially as
described and illustrated in the accompanying drawings.
3. In an adjustable spanner or the like comprising a bar having two jaws one
fixed and the other movable thereon the combination with the bar of an inclined
part such as A3 and with the movable jaw of a set screw or adjusting device such
as D and a gib having an inclined face to correspond with A' substantially as
described and illustrated in the accompanying drawings.

having a tightening or adjusting device of a bar increasing in width as it recedes
from the fixed jaw.
5. The complete adjustable spanner or wrench substantially as described and
illustrated in the accompanying drawings.
