PROVISIONAL SPECIFICATION.
Improvements in Machinery for the Manufacture of Pneumatic
Tyres.
We, HENRY JELLEY of 1, Rothsay Terrace, Coventry in the County of
Warwickshire, Manager, and CHARLES HUBBARD of Whitley Villa, Whitley
near Coventry, in the county aforesaid, Works Manager, do hereby declare the
nature of this invention to be as follows:-
This invention relates to a machine for covering the reinforcing fabrics, covers
or treads of pneumatic tyres with rubber cement or solution for the purpose of
their construction or combination with other parts.
The machine consists essentially of a trough adapted to contain the rubber
solution and of a longitudinal axle passing through the said trough and carrying
one or more rollers for applying the solution to the fabric which is carried over
and in contact with these rollers by another series of loose rollers mounted on an
independent axle the middle rollers of the series having preferably a certain amount
of free play on the axle to allow for the varying thickness of the fabric. The axle
carrying these rollers is mounted in bearings in such a manner that it has free play
in the vertical plane and therefore the rollers it carries rest by their own weight in
contact with the rollers for applying the rubber solution, and it is also so mounted
that it can be raised at one or both ends to allow the length of fabric to be placed
round the rollers. The ring of fabric is stretched between these series of rollers
and another roller the axle of which is mounted in bearings which are adjustable on
the frame of the machine, so that a ring of fabric of any length can be stretched and
solutioned. The fabric is caused to travel over the solutioning roller or rollers by
rotating one or both of the rollers carrying it.
It will be understood that the amount of solution applied to the fabric will depend
upon the width of the rollers, the number of them, and their position with respect
to one another, and in order to regulate the amount of solution applied a scraper is
mounted on the front of the trough which is adapted to bear against the fabric to
which the solution has been applied and remove all superfluity, the operating face
of the said scraper being shaped to correspond with the width, uumber and distance
apart of the rollers on the solution trough.

COMPLETE SPECIFICATION.
Improvements in Machinery for the Manufacture of Pneumatic
Tyres.
We, HENRY JELLEY of 1, Rothsay Terrace, Coventry in the County of
Warwickshire, Manager, and CHARLES HUBBARD of Whitley Villa, Whitley
near Coventry, in the county aforesaid, Works Manager, 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 a machine for covering the reinforcing fabrics, covers

page_text: or treads of pneumatic tyres with rubber cement or solution for the purpose of
their construction or combination with other parts.
In the accompanying drawing which illustrates this invention :-
Figure 1 is a view in side elevation and
Figure 2 is a view in plan..
In both views like parts are marked with like letters of reference.
The machine consists essentially of a trough A adapted to contain the rubber
solution, of a longitudinal axle B mounted in suitable bearings on or in the said
trough, of one or more rollers C adapted to take up and apply the solution to the
fabric or other material, and of a series of loose rollers D mounted on an axle d
and a roller E mounted adjustably on the trough A or on an extension thereof the
two forming a stretching device to receive the fabric or material to be treated.
When the rollers D are not in use, they and the axle carrying them.are placed in
a recess in the extension A' of the trough.
The number and width of the rollers C on the axle B will depend upon the parts
of the strip of fabric or other material to be solutioned. To prevent too much
solution adhering to the rollers C gauges such as a are fixed to the top of the
trough A. The axle d carrying the loose rollers D is mounted in bearings
arranged to slide in vertical guides such as G carried by the trough so that the said
rollers lie by their own weight on the rollers C, and the eyes of the said rollers are
slightly larger than the axle on which they are nounted to allow them a certain
amount of free play. The bearings carrying the axle d and the bearings F carrying
the roller E are so guided and mounted that the rollers D and E can be lifted to
allow the fabric or other material to be placed around them. The fabric or material
is stretched around and between the rollers D and E and the bearings F carrying
the latter are so mounted on an extension A¹ of the trough that the position of
the said roller with respect to the rollers D can be readily varied to stretch the
fabric or material so that it will travel round with said rollers when the axle B is
rotated which may be effected either by a hand crank such as H as shown, or by
power through suitable pulleys.
It will be understood that the amount of solution applied to the fabric will depend
upon the width of the rollers C, the number of them, and their position with respect
to one another, and in order to regulate the amount of solution applied by the rollers
a scraper such at J is mounted on the front of the trough which is adapted to bear
against the fabric to which the solution has been applied and remove all superfluity,
the operating face of the said scraper being shaped to correspond with the width,
number and distance apart of the rollers C.
We wish it to be particularly understood that we do not limit ourselves to the
precise details of construction hereinbefore described and illustrated by the
accompanying drawing, but that we hold ourselves at liberty to make such changes
and alterations as fairly fall within the spirit and scope of our invention.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
The improved machine for applying rubber cement or solution to the parts of
pneumatic tyres for constructive purposes as hereinbefore described and illustrated
by the accompanying drawing.
