Norwich in the County of Norfolk, do hereby declare the nature of this invention.
to be as follows:-
The spanner or wrench is made adjustable by pivoting the divided handle at the
end, as shewn at Fig. 1. A bolt A. with a milled hexagon or thumb nut controls.
the adjustment the two halves of the divided handle being pushed apart by a spring
of suitable material.
Fig. I as shewn is suitable for nuts of bolts, and also for use with loose.
attachment B converting the spanner into a pipe wrench.
Fig. II is a pipe wrench provided with a loose serrated jaw of steel, held in.
its place by loose rivet B. A slight play or movement is allowed for rivet B
preventing the teeth of jaw from being broken when releasing the wrench from the
pipe.
The spanner and wrench are adjustable as described in foregoing Specification.
and as shewn in accompanying drawings.

EDWARD TOWLSON of 12 Bloomsbury Place, Norwich, Engineer and CHARLES.
ALBAN GUNTON of 36 Bridge Street, St. Georges, Norwich, Merchant, 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:
The object in designing the invention which is the subject of the prosent Speci-
fication has been to produce an adjustable spanner of an improved type, capable of
being used also as a pipe wrench.
Referring to the accompanying drawings,―
Figure I is an adjustable spanner and
Figure II is an adjustable pipe-wrench.
Both the spanner and wrench are constructed by providing the two halves A
and B, of suitable material; and pivotting them at C, by bolt & uut, rivet or pin.
The adjustment is effected and controlled by the bolt D which passes through the
two halves. A and B and is fitted with a nut E, which may be either square,
hexagon or round. The two halves A and B are kept distended by the bow-
spring F, which causes the two halves A and B to separate when the nut E is.

unscrewed. The spring F has two projections and F" which are inserted in a
space, provided for that purpose on each half of the pivotted joint.
The pipe wrench shewn at Fig. Il has the jaw G provided with a removable and
renewable face H, which is made of steel, serrated and hardened.
It is attached to the jaw G by n screw, or a rivet or any other convenient
method.
"
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
"
i
(Firstly.) In an adjustable spanner or pipe wrench, the dividing such spanner
or wrench into two halves, and pivotting them; substantially as shewn and
described!
"

(Secondly.) In an adjustable spanner or pipe wrench, the method of adjustment
by common bolt and nut, substantially as shewn and described.
(Thirdly.) In an adjustable pipe wrench the dividing such wrench into two halves,
and pivotting them; and the provision and application of a renewable face of
serrated steel, substantially as shewn and described.
