PROVISIONAL SPECIFICATION.
An Improved Screw Binding Appliance for the Running Tyres of
Velocipedes or other Road Vehicles.
I,'John HaldeN CRESSWELL, of No. 8 Pleasant Row, in the City and County
of Newcastle-upon-Tyne, Sausage Maker, do hereby declare the nature of this
invention to be as follows:-
My invention relates to the right and left hand binding screws by which the
running tyre is secured by screwing up the tapped sockets on the ends of the
binding wire, or is detached by unscrewing said sockets in the opposite direction.
In effecting the latter operation if the right and left hand screws are given too
many turns the screwed sockets come off the ends of the screws and when this
bappens, as it frequently does, the machine is disabled as it is extremely difficult,
in fact practically impossible, for the rider to re-enter them on the threads. If
the right and left hand screws in replacing the tyre be turned in the wrong
direction by mistake the same unstripping of the sockets takes place and this has
been found so serious a drawback that the use of the right and left hand screw
fitting is being to a great extent abandoned, although it is, in every other respect,
admirably adapted for its purpose.
I propose by my invention to connect the sockets by means of a "bridle "
piece, preferably flexible, one end of which is fixed to one socket and the other
end slides through a guide on the other socket and has upon it a collar or stop
which coming against the guide, when the sockets are screwed apart to the proper
extent, prevents them being further separated and coming off the threads of the
right and left hand screws. Two or more "bridle" pieces may be fitted but one
is preferable and a suitable cavity or channel will be formed along the socket to
allow the bridle" piece to work freely in the india rubber.

An Improved Screw Binding Appliance for the Running Tyres of
Velocipedes or other Road Vehicles.
I, JOHN HALDEN CRESSWELL, of No. 8 Pleasant Row, in the City and County
of Newcastle-upon-Tyne, Sausage Maker, 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 screw binding appliance for the running
tyres of velocipedes or other road vehicles, as I will now proceed to explain by
reference to the accompanying drawings; in which
Figs. 1, 2, 3, and 4 shew the right and left hand screw appliance, drawn for
clearness to twice the actual size, and Figs. 5 and 6 shew-it-of-its actual size.
applied to the pneumatic tyre of a velocipede wheel.
Referring to Fig. 1, the appliance is shewn in plan partly sectional with the
sockets A A screwed out to their fullest extent by the right and left hand
screws B B formed upon the turning piece C, and in this position the screws are
prevented coming out of the sockets by the "bridle" piece D, which clasps and

to make a loose fitting, instead of fixing one end to one of the sockets, by which
I save length which is of the greatest importance, and I also form it of a
semicircular or trough like section to prevent the key pin, used in turning the
screws by the holes in C, penetrating the canvas or india rubber of the edges of
the tyre as shewn in Fig. 2 which is a cross-section through a- of Fig. 1. At
the ends it forms nearly a circle which clasps the socket as shewn in Fig. 3, which
is a cross-section through-e-d of Fig. 1, and is retained thereon by the casings FF
which slip over and are soldered on the sockets, the bridle" working through a
guide formed by one half of the collars EE being cut away. Fig. 4 shews in
side view the appliance with the sockets screwed close up to the turning piece C,
the limit of the binding effect of the wire G around the tyre.
Referring to Figs. 5 and 6, the right and left hand screw appliance is shewn in
position within the overlapping edges of the tyre T, in the hollow cavities of the
rim R, the sockets A A being partly drawn together by the screws B B so as to
bind the tyre to the rim by the wire G. The turning piece C is accessible for
operating the screws in either direction, by a small portion of the edge of the tyre
being slit so as to be folded back as shewn in dotted lines on Fig. 6 to allow of the
introduction of the key pin (which is simply a piece of wire or a nail) into the
holes in C. If required a small portion of the rim may be cut out to allow
the edge of the tyre to be folded back as indicated on Figs. 5 and 6.
It will be seen that when the sockets are screwed together as shewn on Fig. 5,
the appliance occupies a very short space and fits the curve of the rim by the
sockets being shaped as shewn on Fig. 4. The sockets A A being entered upon
the threads of the screws B B the bridle piece D is applied and the cases FF
slipped over the sockets and soldered thereon when the turning piece C being
rotated by the key the sockets travel together upon the screws from the ends of
which they cannot be unscrewed when the tyre is to be taken off the rim. The
tyre when the binding wire is drawn tightly around the rim by the screws is
perfectly fastened independently of the inflation of the air tube, and any liability
to "creep" upon the rim is entirely prevented.
Having now particularly described and ascertained the nature of said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1st. The application to the running tyres of velocipedes or other road vehicles,
for the purpose of securing the tyre to or detaching it from the rim, of a right
and left hand screw appliance, provided with a "bridle" piece which will prevent
the sockets coming off the ends of the screws, and protect the india rubber or
canvas from injury by the key pin in turning the screws, substantially as described.
2nd. The improved screw binding appliance, consisting of the sockets A A, the
right and left hand screws B B, on a turning piece C, and a "bridle" D acting as
a stop to the sockets when unscrewed and as a shield to protect the tyre from
injury, constructed and operating substantially as described and shewn, with the
objects herein before stated.
