Improvements in and applicable to Pneumatic Tyres.
HENRY SMITH 154 Noel Street Nottingham Lace Draughtsman do hereby
declare the nature of this invention to be as follows:-
This invention, which relates to improvements in the means for connecting the
ends of the wires used for holding on the covers of pneumatic tyres, has for its
object the provision of means by which the ends of the wires may be readily
connected together, and disconnected as required.
According to one arrangement a suitably shaped bend is formed in or near each
end of the wire. The bend at one end of the wire is then passed through a collar,
and the other end of the wire is inserted in the collar up to the bend in the wire.
Both bends are thus on the same side of the collar and they are so placed with
regard to each other that the bend in each wire prevents the other wire being
drawn past it. A loose coupling is placed round the wires in such a position that
the bends in the wires are between the collar and the coupling.
In another arrangement the ends of the wires are bent at right angles to the
wire, and are held upon a suitably shaped piece by collars or clips.
In a third arrangement the extremities of the wire are fitted with heads which
are so grooved that one end of the wire will lay in the head on the other wire.
The clip used with this arrangement comprises two couplings one of which is
fitted to turn on the other. Both couplings are provided with a longitudinal slit
through which both ends of the wire are laid. The outer coupling is then turned
and prevents the wire passing through the slit in the inner coupling.
In a fourth arrangement one end of the wire is bent and passed through a tube
until the bent end of the wire can be hooked into a hole in the tube. The other
end of the wire is bent and after being passed through the tube above mentioned is
hooked to a plug which is then pushed into the tube.
These arrangement may be used with wires embedded in the covers or with
wires, the ends of which come through the cover and lay in the rim or pass
through the same.

COMPLETE SPECIFICATION.
Improvements in and applicable to Pneumatic Tyres.
HENRY SMITH 154 Noel Street Nottingham Lace Draughtsman 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 improved means for connecting together the ends of the
wires used for holding the covers of pneumatic tyres onto the wheel rims, the
object of the invention being the provision of means for enabling the ends of
the wires to be readily connected and disconnected as may be required.

page_text: In order that this invention and the manner of performing the same may be
readily understood there is attached hereto one sheet of drawings which are
referred to in the following detailed description.
Fig. 1 is a general view of a tyre fitted with one of the connections hereinafter
described.
Figs. 2. 3. 4. 6 and 8 are longitudinal sections of different connections, and
Figs. 5. 7 and 9 are transverse sections of Figs. 4. 6 and 8 respectively.
In pneumatic tyres, as generally constructed, the air tube a Fig. 1 is surrounded
on the outside by a cover b, the edges of which are fitted with one or more wires c
made into rings of such a diameter that when at the bottom of the rim d at one
side of the wheel, the wire can be forced over the edge of the rim at the other side
of the wheel. In Fig. 1 the parts are shown in position and one method of
connecting together the ends of the wire, part of the rim being broken away and
the cover divided at to show the wires and the connection e.
In the arrangement illustrated by Fig. 2 the ends ƒ and g of the wire are bent
at f1 and g and after being placed in the relative positions shown, couplings or
ferrules and ; are moved over the two wires. One of the couplings may be
fastened to one of the wires as indicated by the coupling on the wire g and it will
be seen that after the wires are in position any tendency to separate the ends brings
the bends and g¹ together and prevents the separation.
In Fig. 3 the ends and g of the wire are bent as shown at f¹ and g¹. The ends
are then laid upon a piece k and held there by collars hand; when the tendency
of the wires to separate longitudinally is resisted by the bends f¹ and gl.
In the arrangement shown in Figs. 4 and 5 the wire end f is provided with a
fixed head or collar fl and the wire end g with a piece which has a collar g' and
shank g both of which are grooved as shown at g³ for the reception of the wire f¹.
The collar is also grooved for the wire and the wires and g are held together
by a coupling provided with a slot h¹. For connecting the ends of the wires the
coupling is placed over the collar with the slot in such a position that
the wire can be passed through it into the slot, g. After this has been done
the collar is given a half turn to prevent the wire leaving the same.
The arrangement shown in Figs. 6 and 7 is a modification of the arrangement
shown in Figs. 4 and 5. The head g¹ in this arrangement is made in one with a
tube which answers the same purpose as the collar h Figs. 3 and 4 and the
head is made with a shank to fit the inside of the tube 92. With this arrange-
ment the ends of the wires are brought past each other until the wire fwill pass
through the slot 9, after which the part f' is passed within the tube g³ and the
ends thereby held together.
In the arrangement shown in Figs. 8 and 9 the wire 9 is passed through a slot in
the head of a piece k and is bent at g¹ to hook on to the piece k. The end of the
wire fis bent at f¹ to fit a bole in the coupling k and when in position the wires
are secured by a sliding collar h.
When any of the herein described arrangements are used on shallow rims the
ends of the wires are carried some little distance beyond the coupling so that the
wires may be more easily disconnected to allow of the cover being removed from
the wheel 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:-
1. The method of and means for connecting together the ends of the wires used
for holding on the covers of pneumatic tyres as shown in Fig. 2 and herein
described.
2. The method of and means for connecting together the ends of the wires used
for holding on the covers of pneumatic tyres as shown in Fig. 3 and herein

described.
4. The method of and means for connecting together the ends of the wires used
for holding on the covers of pneumatic tyres as shown in Figs. 6 and 7, and herein
described.
5. The method of and means for connecting together the ends of the wires used
for holding on the covers of pneumatic tyres as shown in Figs. 8 and 9 and herein
described.
