PROVISIONAL SPECIFICATION.
Improvements in Adjustable Spanners for Cyclists and others.
We, JOHN THOMPSON, CHARLES EVERARD, and JOHN HARRISON, trading as
The Elliptic Cycle Company, of 13, Brook Street, Peterborough, in the County of
Northampton, Manufacturers, do hereby declare the nature of this invention to be
as follows:-
This invention retates to an adjustable spanner having a pair of jaws at each
end and provided with a worm or screw arranged to adjust both pairs of jaws.
A spanner constructed according to the said invention is made in two parts or
halves, the ends of each half forming the inner jaw of one pair of jaws and the
outer jaw of the other pair of jaws, the said ends being so shaped and arranged that
when one pair of jaws is quite closed the other pair is more or less open, whereby,
whatever may be the position of the jaws one pair will always be adapted for
larger sized nuts than the other pair. The two bars carrying the ends forming
the jaws slide one upon the other and are held together by clips or stirrups, one
clip preferably being fixed to each bar and embracing the other bar. One of the
bars is recessed and carries a screw or worm which engages with teeth on the other
bar; the worm is carried upon a spindle which is flattened at its ends.to enter slots
and then rivetted or burred over to fix it in position.

Improvements in Adjustable Spanners for Cyclists and others.
We, JOHN THOMPSON, CHARLES EVERARD and JOHN HARRISON, trading as
The Elliptic Cycle Company, of 13, Brook Street, Peterborough, in the County of
Northampton, Manufacturers, 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 an improved adjustable double spanner, that is to say,
a spanner having a pair of jaws at each end aud a worm or screw for adjusting
both pairs of jaws simultaneously.
According to our invention we make the spanner in two parts or halves, the ends
of each half forming the inner jaws of one pair of jaws and the outer jaw of the
other pair of jaws, the said ends being so shaped and arranged that, when one pair
of jaws is quite closed, the other pair is more or less open, whereby whatever may
be the position of the jaws, one pair will always be adapted for larger sized nuts
than the other pair.
The two halves carrying the ends forming the jaws slide one upon the other and

page_text: are held together by clips or stirrups, one clip preferably being fixed to each part
and embracing the other part. One part is recessed and carries a screw or worm
which engages with teeth on the other part; the worm is carried upon a spindle
which is flattened at its ends to enter slots and then rivetted or burred over to fix
it in position.
In the accompanying drawing,-
Figure 1 is a side elevation of a spanner made according to our invention:
Figure 2 is an elevation at right angles to Figure 1; and,
Figure 3 is a section on the line 3-3 Figure 1.
a and bare the two parts or halves of the spanner, the said parts or halves being
arranged so that at one end they form the outer jaws a¹ and of the two pairs of
jaws, the other ends a² and 2 being arranged to form the inner jaws. The jaw a¹
is made to fit a larger nut than the jaw b
c is the worm or screw with which the half or part b is provided the said worin
being mounted loosely upon a spindle d which is flattened at its ends to enter
slots e, e in a recess in the half and is then rivetted or burred over to fix it in
position as described. g, g are the teeth formed in the half or part a and with
which the worm or screw c engages.
h, are the clips or stirrups rivetted to one end of each of the halves, and' in
which the other ends of the said halves slide when the worm e is turned.
With this construction of spanner it will be obvions that, by rotating the worm,
the ends forming the jaws will be caused to approach or recede from one another
according to the direction in which the worm is turned whereby they will be
adapted for different sized nuts, and it will also be obvious that one end of the
spanner will always be arranged to receive larger nuts than the other end.
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 :-
1. An adjustable double spanner formed of two halves or parts the ends of which
form jaws, the parts being connected together so as to slide one upon the other and
provided with a worm and teeth for moving them and being of such relative length
that when one pair of jaws is closed the other pair is more or less open, substantially.
as, and for the purpose, described.
2. In a double spanner having two bars held together by clips and provided with
a worm screw for moving one bar on the other, a spindle on which the worm screw
is loosely mounted, the ends of such spindle being flattened and fitted into two
narrow slots in one of the bars, and then secured there by having such ends rivetted
or burred over upon the bar, as set forth.
3. The manufacture and use of the improved adjustable spanner for cyclists and
others hereinbefore described and illustrated in the accompanying drawing.
