House, New Broad Street, in the City of London, Engineers, do hereby declare
the nature of this invention to be as follows:-
This invention relates to improvements in spanners and has for its object to
provide a simple spanner adapted to be used in tightening nuts in places difficult
of access by ordinary spanners.
According to the invention we provide a suitable ratchet brace, the ratchet
wheel of which is mounted upon a spindle, the lower end of which is arranged
so that it can be caused to engage with any one of a series of spanner boxes of
different sizes. In practice a suitable form of connection between the ratchet
spindle and the spanner boxes is formed by slotting or notching the lower end
of the said spindle and the upper ends of the spanner boxes.

Improvements in Spanners.
We, ROBERT HOARE, of 93, Bartholomew Close, in the City of London,
Merchant, and The ANGULAR HOLE MACHINE COMPANY LIMITED, of Dashwood
House, New Broad Street, in the City of London, Engineers, 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 improvements in spanners and has for its object to
provide a simple spanner adapted to be used for turning nuts in places difficult
of access by ordinary spanners.
According to our invention we make use of a ratchet brace the spindle of which
is adapted at each end to carry a box or socket designed to fit the nut to be
turned. The nut boxes are designed to be readily applied to and removed from
the spindle, and a suitable form of connection consists of a dove-tailed tongue
upon each end of the spindle designed to fit corresponding dove-tailed grooves
or slots in the nut boxes.
To enable our invention to be fully understood we will describe the same by
reference to the accompanying drawing, in which :-

is the spindle of the ratchet brace and b is the lever which works upon t
said spindle and carries a spring pawl c designed to engage with a ratch
wheel fixed upon the spindle the said ratchet wheel being arranged between t
two limbs e, e of the lever.

As shewn in the drawing the spindle a is formed with the boss f, with th
two circular portions g, 9 upon which the limbs e, e rotate, with the square po

mounted and with the square portion i designed to carry the detachable boss

1,7 are nut boxes designed to be detachably connected with the bosses f and j
as shewn in the drawing, each of the said bosses is formed with a dove-tailed
projection m and the bosses are each formed with a corresponding recess n so
that the said nut boxes can be readily engaged with and disengaged from the
bosses on the spindle.
It is to be understood, however, that any suitable means may be provided for
permitting of the said nut boxes being readily connected with and disconnected
from the spindle a.
both ends of the spindle is to allow a ratchet brace, the spindle of which can be
The object of providing for attaching the nut boxes to
turned in one direction only, to be used for either screwing or unscrewing nuts,
the nut boxes being placed upon one end or the other of the said spindle according
to the direction in which the nut is to be turned; where, however, a ratchet brace
is used which is capable of being turned in either direction then obviously it
will only be necessary to provide for attaching the nut boxes to one end of the
spindle.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:
1. In a spanner the combination of a 'spindle, a nut box adapted to be readily
connected with and disconnected from the end of the said spindle, a lever loosely
mounted upon the spindle and means for imparting movement from the said
lever to the spindle, substantially as described.
3.
2. In a spanner the combination of a spindle, a boss at each end of the said 40
pindle, a lever mounted upon the spindle between the bosses, means for impart-
ng motion from the lever to the spindle and nut boxes designed to fit the nuts
be moved, the said nut boxes and bosses being so constructed that the nut
oxes can be readily connected with and disconnected from the bosses, sub-
antially as described.
