PROVISIONAL SPECIFICATION.
Improvements in Connecting Air Supply Tubes to Pneumatic
Tyres.
I, HARRY HEATON, the younger, Managing Director, of Lifford Mills, Kings
Norton, in the County of Worcester, do hereby declare the nature of this invention
to be as follows:-
:-
-
My invention relates to an improved method of attaching an air supply tube to,
the rubber tube of a pneumatic tyre. In connecting such tubes by existing
methods considerable difficulty is experienced because of the tendency of the
pneumatic tube to draw away from the washers securing the air supply tube when
the said pneumatic tube is inflated.
My invention consists in a method of preventing the drawing away of the
pneumatic tube by means of a novel kind of rubber washer.
In constructing a rubber washer for this purpose I insert in the washer a canvas
ring concentric with the aperture of the washer and dividing the rubber washer into
two annular rings. Sometimes I apply a compound washer of this description
inside the pneumatic tube as well as outside and when I screw up the two washers
by means of a screw nut the washers compress the rubber of the tube and the
canvas ring indents the said rubber and grips it firmly. When the pneumatic tube
is inflated the canvas ring entirely prevents the rubber from being drawn away
around the air supply tube and at the same time makes a joint which is quite
air tight.
I apply my improved compound washer either on the inside or the outside of the
pneumatic tube or on both inside and outside.
To back up my washers I arrange the air tube in the usual manner and adopt
the usual flat nut and metal washer.

COMPLETE SPECIFICATION.
Improvements in Connecting Air Supply Tubes to Pneumatic
Tyres.
I, HARRY HEATON, the younger, Managing Director, of Lifford Mills, Kings
Norton, in the County of Worcester, 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 an improved method of attaching an air supply tube to
the rubber tube of a pneumatic tyre. In connecting such tubes by existing
methods considerable difficulty is experienced because of the tendency of the
pneumatic tube to draw away from the washers securing the air supply tube when
the said pneumatic tube is inflated.
My invention consists in a method of preventing the drawing away of the
pneumatic tube by means of a novel kind of rubber washer.

page_text: Referring to the accompanying sheet of drawings :-
Figure 1 is a section of a pneumatic tyre showing the position of the rubber
washers relative to the other parts.
Figure 2 is a plan of my new washer and
Figure 3 is a section.
Figures 2 and 3 are drawn to a larger scale than Figure 1.
In constructing a rubber washer for this purpose, I insert in the washer Ca
canvas ring D, Figures 2 and 3, concentric with the aperture of the washer and
dividing the rubber washer into two annular rings. Sometimes I apply a compound
washer of this description inside the pueumatic tube as well as outside, and when I
screw up the two washers by means of a screw nut the washers compress the rubber
of the tube and the canvas ring indents the said rubber and grips it firmly. Such
washers are shown in position at CC Figure 1.
When the pneumatic tube is inflated the. canvas ring D entirely prevents the
rubber from being drawn away around the air supply tube, and at the same time
makes a joint which is quite air tight.
I apply my improved compound washer either on the inside or the outside of the
pneumatic tube or on both inside and outside.
To back up my washer I arrange the air tube in the usual manner and adopt the
usual flat nut and metal washer.
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 :-
A rubber washer for connecting the air tube to a pneumatic tyre, having a
canvas ring embedded in, or forming part of the washer and dividing the washer
into two annular rings so that when the air tube is gripped between the washers or
by the washer, the canvas ring indents the rubber of the air tube and grips it
firmly, so preventing the rubber from being drawn away round the air supply tube
substantially as hereinbefore described.
Dated this 30th day of April 1894.
