PROVISIONAL SPECIFICATION.
Improvements in and in connection with Pneumatic Tyres.
I FRANCIS PEGLER, of Retford, in the County of Nottingham, Rubber
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention has for its object to provide efficient means for joining together
the ends of the flexible tubes employed in forming the inner air tubes or chambers
of pneumatic tires, or the tubes forming the pneumatic tires themselves, in the
case of single tube tires.
In an air tube constructed according to this invention, one end of the tube to be
joined is closed by a diaphragm at a short distance within it, and inside the open
free end thus formed is inserted or formed a collar ring, or the like, at a short
distance from the said diaphragm, whilst the other end is similarly closed and has
formed on it a corresponding external collar or the like, the two ends so constructed
forming a kind of spigot and faucet jointing device.
• In order to join the two ends of the tube the spigot or plug end, having the
external collar, is folded longitudinally and passed into the corresponding open
faucet or socket end until the two closed ends are adjacent, and the internal and
external collars have passed.each other, when the plug end is released, the said
projecting collars, then locking the ends in this closed position and thereby
effectually preventing their separation until the spigot or plug end is again
compressed so as to allow the passage of of the said locking collars past each
other.
When employing this invention for jointing together the ends of single tube
pneumatic tires the said ends are left open, and after joining them by passing the
locking collars into position, in the manner herein before described with reference
to inner air tubes, the overlapping socket end is secured by rubber or other cement
to the plug end in the usual manner.

Improvements in and in connection with Pneumatic Tyres.
I FRANCIS PEGLER, of Retford in the County of Nottingham, Rubber
Manufacturer, 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 has for its object to provide efficient means for joining together
the ends of the flexible tubes employed in forming the inner air tubes or chambers
of pneumatic tyres, or the tubes forming the pneumatic tyres themselves, in the
case of single tube tyres, and consists essentially in securing them together by
means of suitable interlocking devices.

page_text: In the accompanying drawings:
Fig. 1 shows a vertical section of two ends of an air tube constracted according
to this invention, and, Fig. 2 is a similar view of a modified arrangement of the
same.
Referring to Fig. 1 of the drawings, one end a of the air tube to be joined is
closed by a diaphragm 6 at a short distance within it, and inside the open free
end c thus formed is inserted or formed a collar ring d whilst the other end e is
similarly closed by a diaphragm f and has formed on it a corresponding collar or
groove g the two ends so constructed forming a kind of spigot and faucet jointing
device.
In the modified arrangement shown in Fig. 2 the two closing diaphragms b, f
(Fig. 1) are divided or replaced by cross webs h, i placed at a short distance apart
aud joined by inclined parts thus forming when placed in position as shown,
and inflated, a secure dovetail jointing device. By this means a pliable yielding
joint is obtained which readily permits of the free expansion of the tube when
inflated.
When employing this invention for jointing together the ends of single tube
pneumatic tyres the said ends are left open, and after joining them in the
imanner hereinbefore described with reference to inner air tubes, the overlapping
socket end is secured by rubber or other cement to the plug end in the usual
manner.
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. A joining device for the air tubes of pneumatic tyres consisting in closing the
ends to be joined and securing them together by means of interlocking connections
substantially as described.
2. The arrangement and construction of interlocking devices for securing the
ends of pneumatic tyres and air tubes substantially as described and shown.
