Improvements in connection with Spanners for the Use of Cyclists
and others.
I, JOHN WILLIAM COCKERILL of 5 George Street, Hanover Square,
London, W., Physician and Surgeon, do hereby declare the nature of this
invention to be as follows:-
My invention relates to spanners for the use of cyclists and others and consists
in forming the handle of the spanner (which may be of any suitable kind) with a
slightly curved end so that it can be used as a tyre lifter as and when required.
The curved part may be of metal, or preferably of bone, ivory, horn, vulcanite, or
other suitable material or combination of materials. In the case of screw spanners,
the screw-threaded stem of one of the jaws can be taken out and inserted under
the lifted tyre to keep it above the rim, while the lifting end is being used at
another part of the circumference of the tyre.

Improvements in connection with Spanners for the Use of Cyclists
and others.
I, JOHN WILLIAM COCKERILL late of 5 George Street, Hanover Square,
London, W., and now of 17 Whitehall Place, London, S.W. Physician and
Surgeon, 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 :-
My invention relates to spanners for the use of cyclists, and others using
vehicles with detachable, and especially with wired on pneumatic tyres. To
detach such tyres it is almost a necessity to use a suitable tyre lifter and the
operation is still more easy to perform with two such instruments; one being used
to keep the lifted wire above the rim, forming a fixed point, while it is worked off
with the other. It is also convenient to have such an instrument or instruments
combined with a spanner. My invention, therefore, consists broadly in forming
the handle of the spanner, which may be of any suitable kind, with a curved end
shaped so as to form a convenient tyrelifter; and further one of the jaws, with
its stem can be made removable, the stem having a curved end, in the manner, and
for the purpose above described.
In order to more fully explain my invention I make reference to the accom-
panying sheet of drawings in which
Fig. I is an end view of the upper blade withdrawn showing the threaded
stem, and curved end for use as a tyre lifter.

page_text: Fig. II an end view of the spanner with upper blade in place, and showing the
curved end of the handle forming a second tyrelifter, and Fig. III a side view of
the same.
Similar letters refer to the same part, A, the upper jaw, B. the threaded
stem, C, the end which forms the tyre lifter to hold the wire above the rim as
described, D, the lower jaw, E, the handle, F, the curved end forming a second
tyrelifter for working off the tyre; G a screw nut made to fit the thread of the
stem of the upper jaw; by turning which the separation of the jaws is adjusted,
H, hollow in spanner handle to accommodate the end C, when the jaws are closed.
I have illustrated the form of spanner which I think to be the best, but I do
not restrict myself to the precise shape, configuration, relative proportions, or
disposition of parts, as described in the above specification, or exemplified in the
accompanying drawings, as any or all of them can be considerably varied without
departing from the spirit of my invention.
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 :-
I. In spanners for the use of cyclists and others, constructing the handle with
a curved end shaped so as to form a convenient tyrelifter, the whole substantially
as described in the above specification, and exemplified in the accompanying
-drawings.
11. Constructing spanners capable of being divided into two parts, each part
having a curved end, shaped so as to form a convenient tyrelifter, the whole
substantially as described in the above specification, and exemplified in the
accompanying drawings.
III. Constructing spanners, one of the jaws with its stem being removable, and
the stem having a curved end shaped so as to form a convenient tyrelifter, the
whole substantially as described in the above specificatiou, and exemplified in the
-accompanying drawings.
