WALTER HAM 8 New North Street Theobalds Road London W.C. Cycle
Manufacturer do hereby declare the nature of this invention to be as follows:-
(A.) A stud nipple (C, Fig. 2) tapped to screw on wire (A). The wire (B) to be
bent (D) Fig. 1.
(B.) The end of H wire (Fig. 4) to be bent & flattened so as to form a stud G
(Fig. 4). E wire to be tapped (Fig. 3). A hooked nipple (F. Fig. 3) to screw on
E wire (Fig. 3).
(C.) The stud nipple C as in Clause A (Fig. 2). A hooked nipple F as in
Clause B (Fig. 3).
I
(D.) A stud G as in Clause B (Fig. 4). A bent wire D as in Clause A (Fig. 1).
(1.) The ends of a wire (used as one coil or a plurality of coils) to be bent or
have an attachment severally described as above to be used as a means of attaching
pneumatic tyres, cushion tyres, or solid tyres to the rims of bicycles, tricycles,
cabs, carriages and any other sort of vehicle.
(2.) The attachment on a wire or end of a wire (G on A).Fig. 2 to have a. thin
neck (I, Fig. 2) this neck to pass through end of loop D (Fig. 1).
(3.) The description in Clause 2 above to apply to the mode of attachment of
ends of wire as severally described in Clauses A, B, C,.D.
(4.) The attachments as herein before set forth allow of adjusting-i.e.-increasing
or decreasing the circumference of the coil or coils of wire and connecting and
disconnecting the ends of the aforesaid coil or coils of wire thereby allowing the
tyre to be fitted on or taken off the rim expeditiously.
(5.) The invention above severally described relates to the mode of attaching
pneumatic and other tyres to rims by the aid of wires and other appliances herein
set forth.

Improvements relating to Pneumatic and other Elastic Tyres.
I, WALTER HAM, of 8 New North Street, Theobalds Road, London, Cycle 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
My invention relates to pneumatic and other elastic tyres and in particular to
that kind or class of tyre which is secured to the rim by a circumferential wire or
wires in a manner well known in the trade.
The object of my invention is to provide improved devices for connecting the
ends of the wire together to form a complete circle which devices at the same time
permit the circumference of the wire circle to be increased or diminished if desired
thus allowing the wire to be placed on and taken off the rim very easily and
expeditiously.

page_text: According to my invention I screw to one end of the wire a hooked nipple or form
the end of the wire into a hook, the other end of the wire is correspondingly
formed with a stud at right angles to the wire, or has a nipple of similar shape
screwed on. The stud and hook are of a suitable shape so as to be readily put in
engagement with each other when desired.
In order that my invention may be clearly understood I will now proceed to
describe the same with reference to the accompanying drawings which illustrate my
improved devices.
Referring to Figure 1 the end of the wire A is merely bent into a hook A¹
adapted to engage with a stud such as shewn in Figure 2 in which figure B is a
nipple tapped to fit the screwed end of the wire A and having a stud C formed at
the side. Figure 3 shews a nipple D formed with a hook D₁ which is screwed on
the wire and Figure 4 shews a stud A' formed at the side of the wire itself. It will
be understood that the hook shewn in Figure 1 can be used either with the stud
shewn in Figure 2 or with that shewn in Figure 4 and this is also the case with
the hook shewn in Figure 3. The part of the wire or nipple carrying the stud is
preferably formed with a thin neck as shewn at E in these figures so that the
entrance to the hook may be contracted as shewn in Figures 1 and 3.
My improved devices are also applicable for connecting the ends of a wire coil
which is sometimes employed in placo of the single wire circle for securing a tyre
to the rim.
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
The devices for connecting the ends of a wire to form a circle having one or
several turns for securing an elastic tyre to its rim substantially as described with
reference to Figures 1 to 4 of the accompanying drawings.
Dated this 8th day of September 1896.
