PROVISIONAL SPECIFICATION.
Improvements in or connected with the Attachment of Pneumatic
Tyres to Wheels.
I, CHARLES HENRY GUEST, of Tower Works, Tower Road, Birmingham, in
the County of Warwick, Engineer, do hereby declare the nature of this invention
to be as follows :-
My invention relates to attachments for connecting pneumatic tyres to the rims
of wheels and especially to that class of attachment in which two wires introduced
into the edges of the jacket or covering are employed.
The object of my invention is to provide improved means for connecting the
ends of such wires.
In carrying out my invention I make use of what I will term cam-hooks, one of
which is fixed upon one end of each wire and designed to engage with an eye or loop
upon the other end.
My cam-hook has the hook portion thereof bent to a curve drawn from a
different centre from that upon which the hook is pivotted so that when the point
of the said hook is introduced into its eye and pushed through it, the two ends of
the wire will be drawn together to tighten the wire upon the rim.
In practice I find it advantageous to pivot the curved portion of the hook to
the shank portion thereof so that when the two ends of the wire are connected the
said curved portion can be folded down and will not form an obstruction.
Dated this 25th day of January 1893.

COMPLETE SPECIFICATION.
Improvements in or connected with the Attachment of Pneumatic
Tyres to Wheels.
I, CHARLES HENRY GUEST, of Tower Works, Tower Road, Birmingham, in
the County of Warwick, Engineer, 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 attachments for connecting pneumatic tyres to the rims
of wheels and especially to that class of attachment in which two wires introduced
into the edges of the jacket or covering are employed having two or
convolutions to each wire.

The object of my invention is to provide improved means for connecting the ends
of such wires.
In carrying out my invention 1 make use of what I will term cam or lever hooks,
one of which is fixed upon one end of each wire and designed to engage with an
eye or loop upon the other end.
My cam hook has the tongue portion thereof bent to a curve drawn from a
different centre from that upon which the hook is pivotted so that when the point
of the said hook is introduced into its eye and the hook is closed, the two ends of
the wire will be drawn together to tighten the wire upon the rim.
I sometimes pivot the tongue to the hook proper in the form of a lever so that
when the two ends of the wire are connected the said tongue can be folded down
and will not form an obstruction.

page_text: To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawings, in which :-
Figures 1 and 2 are elevations at right angles to each other of my connecting
attachment; and,
Figure 3 is a view similar to Figure 1 illustrating the operation of my device:
Figures 4 and 5 are views at right angles to each other illustrating a modification
of my invention.
Similar letters of reference indicate corresponding parts in the several figures.
a is the wire, the two ends of which are to be united and b is the hook for uniting
the same.
As shewn in Figures 1 to 3 the hook is pivotted at c to a link d attached to
one end of the wire a, the said wire having at its other end a link or eye e with
which the hook is designed to engage.
The hook b is provided with a curved surface at f, the centre of which is
eccentric to the centre of the pivot c so that when the tongue or point of the hook b
is passed through the link e as shewn in Figure 3 and then folded over to the
position shewn in Figure 1, the surface f will act as a cam to draw the link e
towards the link d, the hook b is also provided with a notch g in which the end of
the link e lies with the hook in the position shewn in Figures 1 and 2.
In the modification of my invention shewn in Figures 4 and 5 the tongue of the
hook is pivotted to the hook proper at h so that when the said tongue is passed
through the loop e in the position shewn in dotted lines in Figure 4 and then folded
over to the position shewn in full lines in the said figure, it will act as a lever to
draw the two ends of the wire together. Also in the modification shewn in
Figures 4 and 5 the hook is represented as being directly attached to the wire a
and the loop is represented as being formed out of the wire itself.
.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is:
1. Attaching a pneumatic tyre to the wheel rim by a wire or wires the ends of
which or of each of which are connected by a hook at one end having a cam-
surface or lever engaging with a loop on the other end of the wire, substantially
as described.
2. In a device for connecting the ends of wires used for attaching pneumatic
tyres to the rims of wheels, a cam-hook at one end of the wire adapted to engage
with a loop on the other end of the wire, substantially as described.
