Improved Machines for Manufacturing Linings for Pneumatic Tyres.
We, ALEXANDER BLACK and DAVID BLACK, both of 456, Victoria Road, Cross-
hill, Glasgow, in the County of Lanark, Scotland, Tyre Manufacturers, do hereby
declare the nature of this invention to be as follows;
-
The object of this invention is to construct a machine for the manufacture of
the fabric lining described in Patent No. 23190/95.
In carrying out this invention, we take two pieces of flattened tubular metal,
each the width of the tapes or pockets, which are provided for the wires, and we
fix them parallel to one another, at the same distance apart as the lining is wanted
in width."
At one end of the parallel tubes we fix two rolls of tapes or pockets. The end
of each tape or pocket is drawn through its corresponding tube, and is caught in
a set of rollers at the other end.
The strip of fabric is then wound round the parallel tubes at an angle of
about 45° to them.
It. then passes through the rollers enclosing the tapes or pockets in its edges,
and is wound up on a spindle. To enable the fabric to adhere to the tapes or
pockets before it goes through the rollers, we may cut a piece off one side of the
parallel tubes.
The parallel tubes and the rolls of tapes or pockets are fixed on a bearing and are
free to revolve. The set of rollers and the spindle on which the finished lining is
wound, are also fixed on a bearing, and are free to revolve. In order that the two
axles may revolve simultaneously, they are connected by a rod or shaft.
Every complete turn of the parallel tubes will take on one complete turn of
the fabric. As everything, except the strip of fabric which is being lapped round
the parallel tubes, revolves, nothing can get twisted or out of place.
The act of revolving the parallel tubes may also be made to roll the lining and
wind it on the spindle at the same time.
Instead of using flattened metal tubes to carry the tapes or pockets, we may
use solid metal rods, and fold the tapes round each of them to form the pockets.
According to another modification, instead of having the parallel tubes or
rods, the rollers, and the tapes, free to revolve, we fix the strip of fabric on an
arm, and make the arm revolve round the parallel tubes or rods carrying the
fabric with it.

We, ALEXANDER BLACK and DAVID BLACK, sometime of 456, Victoria Road,
now of 90, Forth Street, Pollokshields, Glasgow, in the County of Lanark,
Scotland, Tyre Manufacturers, 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:-
The object of this invention is to construct a machine for the manufacture of
the fabric lining described in Patent No. 23190/95.
In order that the invention may be easily understood, we append drawings,
reference being made to the drawings and the figures marked thereon.
In carrying out this invention, we take two pieces of flattened tubular metal,
A Fig. 1, each the width of the tapes or pockets which are provided for the wires,
and we fix them parallel to one another, at the same distance apart as the lining
is wanted in width.
At one end of the parallel tubes we fix two rolls of tapes or pockets, B Fig. 1.
The end of each tape or pocket is drawn through its corresponding tube and is
caught in a set of rollers, C Fig. 1, at the other end.
The strip of fabric, D Fig. 1, is then wound round the parallel tubes, A Fig. 1, at
an angle of about 45° to them. It then passes through the rollers, C Fig. 1, enclos-
ing the tapes or pockets in its edges, and is wound up on a spindle, E Fig. 1. To
enable the fabric to adhere to the tapes or pockets before it goes through the
rollers, we may cut a piece off one side of the parallel tubes, Fig. 2.
The parallel tubes, A. Fig. 1, and the rolls of tapes or pockets, B Fig. 1, are
fixed on a bearing, F Fig. 1, and are free to revolve."
The set of rollers, C Fig. 1, and the spindle, E Fig. 1, on which the finished
material is wound are also fixed on a bearing, F1 Fig. 1, and are free to revolve.
In order that the two axles may revolve simultaneously, they are connected by
a rod or shaft, G Fig. 1.
Every complete turn of the parallel tubes, A Fig. 1, will take on one complete
turn of the fabric, D Fig. 1.
As everything except the strip of fabric, 1 Fig. 1, which is being lapped
round the parallel tubes, A Fig. 1, revolves, nothing can get twisted or out of
place.
The act of revolving the parallel tubes, A Fig. 1, may also be made to roll the
lining, H Fig. 1, and wind it on the spindle, E Fig. 1, at the same time.
Instead of using flattened metal tubes, A Fig. 1, to carry the tapes or pockets,
we may use solid metal rods, A Fig. 3, and fold the tapes round each of them to
form pockets, B Fig. 3.
According to another modification, instead of having the parallel tubes or
rods, the rollers, and the tapes, free to revolve, we fix the strip of fabric on an
arm, and make the arm revolve round the parallel tubes or rods carrying the
fabric with it.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we wish it to be
particularly understood that we do not limit ourselves to the precise details of
construction described and illustrated, but hold ourselves free to make such
alterations as conform with the scope of our invention, and we declare that what
we claim is:-
1. A machine for manufacturing linings for pneumatic tyres substantially as
described and illustrated.

page_text: 2. In combination with a machine for manufacturing linings for pneumatic
tyres as described, two pieces of flattened tubular metal fixed parallel to one another
for the purpose of guiding the tapes or pockets, and keeping the edges of the
lining parallel.
3. The mode of fixing a machine for manufacturing linings for pneumatic tyres
on a bearing so that everything will revolve except the fabric which is being
wound on the parallel tubes or rods.
4. In combination with a machine for manufacturing linings for pneumatic tyres
as described, two solid metal rods for the tapes to be folded over to form pockets
as shown by Fig. 3.
5. A machine as described and illustrated, but not free to revolve, with the
fabric fixed to an arm which is made to revolve round the parallel tubes or rods.
