PROVISIONAL SPECIFICATION.
Improvements in Adjustable Spanners for Axletree-caps of
Wheeled Vehicles.
We, GEORGE WESTON, 39 Harwood Street, Highfields, Sheffield, in the
County of York, Mechanic, and GEORGE WESTON, 57 Duke Street, Park,
Sheffield, in the County of York, Sausage Skin Dealer do hereby declare the
nature of this invention to be as follows:-
We use a square centre-piece to act as a fulcrum, from each side of which is a
projecting arm similar in shape to a tenon. Upon each of the arms is pivoted_n
lever about the centre lengthwise. One end of each of such levers forms the
grasping end of the spanner and is made in such shape as to fit the axletree-cap.
To cause or make the levers to grip the cap a four-sided wedge is forced between
the extreme or opposite ends of the said levers, and so opening those ends and
closing the other ends upon the cap.
We force the wedge between the levers by means of a screw passing through
the centre of the wedge and through the centre of the said square centre-piece
which is bored and screwed to allow of the passage of the screw through it.
When the levers are affixed to a cap it is screwed or unscrewed as may be
required by means of a lever or handle which encloses, or passes round all the four
said levers, and such lever or handle may be moved nearer to, or further away
from the cap as may be required by the depth of the axletree in the wheel.
All the parts may be made of steel or iron or other suitable material.
Dated this 15th day of December 1894.
