Improvements in Apparatus for the Manufacture of India Rubber
Packing, Hose-pipe, and other similar Rolled Fabrics.
We, RICHARD KENNEDY BIRLEY, of the firm of Charles Macintosh and
Company, Limited, of Cambridge Street Works, Manchester, in the County of
Lancaster, India Rubber Manufacturers, and JOHN DEMPSEY, of the same place,
Foreman Hose Maker, do hereby declare the nature of this invention to be as
follows:-
This invention relates principally to the manufacture of what is known as india
rubber packing which is usually made from strips of canvas about sixty feet long
and of a suitable width coated with india rubber, and then rolled up by hand or
otherwise under pressure round an india rubber core; but the same apparatus is
also applicable to the manufacture of hose pipe from india rubber coated canvas
rolled round a metal core which is afterwards forced out by hydraulic pressure;
and for other similar purposes where a strip of india rubber coated fabric is required
to be rolled up into a solid or tubular form.
The apparatus consists principally of a long table (say about sixty two feet)
preferably faced with wood and supported at intervals upon a suitable strong
framework. The face of this table must be level and perfectly true from end
to end.
Along the back of this table there are fixed to the framing at suitable intervals
a series of arms or cranes extending over the table and carrying a long continuous
shaft upon which we fix a series of grooved pulleys.
Over each of these pulleys passes a chain one end of each is attached to the
pulley and the other end is attached to and supports a long iron box, the lower
side of which is preferably faced with wood.
The lower face of this box is made true with the upper face of the table and
when the chains are slackened the box will lie perfectly flat on the table touching
the same from end to end.
Each end of this box is fitted with a set of parallel links and levers so that when
it is raised up from the table it will always remain equidistant from it at all points
and if moved to and fro over the table it will still always keep perfectly parallel.
The chain pulley shaft is driven at one end by worm or other suitable gearing
so that the long box can be thereby raised or lowered as required the first driving
shaft thereof being fitted with two pulleys and two belts one of which is crossed
and the other open so that by moving either belt onto the fast pulley by a strap
fork the chains may be made to raise or lower the long box.
Each arm or crane is provided above the table with a rack capable of sliding
transversely through two bosses in the lower part of the arm so that they are held
and can move in a horizontal position above the table. The front end of each rack
has a hole bored vertically through it and through this hole passes a pin attached
to the back of the long box, so that the racks can move the box to and fro, and at
the same time the latter can be raised and lowered whilst the racks remain in a
horizontal position.
Each rack is in gear with a toothed pinion and these pinions are all keyed on a
long horizontal shaft extending from end to end of the machine and actuated at the
driving end by suitable spur gearing from a main driving shaft which, like the former
one, is also fitted with two pulleys with open and crossed straps moved by a strap
fork so that by moving this latter in the proper direction by a hand lever the long
box can be caused to move transversely over the table in either direction.

page_text: The operation of making a sixty feet length of rolled packing by this apparatus
is as follows :-
A long strip of india rubber coated canvas of a suitable width (according to the
thickness of the roll required) is laid along the front of the table, and a corre-
sponding length of india rubber core coated with varnish is laid along one edge
which is then rolled once round the core by hand.
The long box being in its most backward position the chain pulley shaft is set in
motion so as to raise the long box a certain height from the table and the strap is
then shifted onto the loose pulleys. The attendants then place the rolled edge of
the canvas with the core inside it just beneath the front edge of the long box
from end to end of the table taking care that the canvas lies quite straight without
puckers.
The chain pulley shaft is now caused to revolve in the reverse direction so as to
lower the box onto the rolled edge and slacken the chains so that the weight of the
box rests on the roll.
The pinion shaft is now set in motion so as to cause the racks to push the long
box forwards whereby the canvas is completely rolled-up under pressure of the
whole weight of the box, the latter acting in the same way as the box of an
ordinary mangle.
The box is then raised up and the finished roll of packing can then be removed
being perfectly solid and cylindrical from end to end.
We prefer to make the strip of coated canvas of a number of pieces cut to an
angle of forty five degrees and joined together edge to edge.

COMPLETE SPECIFICATION.
Improvements in Apparatus for the Manufacture of India Rubber
Packing, Hose Pipe, and other similar Rolled Fabrics.
We, RICHARD KENNEDY BIRLEY, of the firm of Charles Macintosh and
Company, Limited; of Cambridge Street Works, Manchester, in the County of
Lancaster, India Rubber Manufacturers, and JOHN DEMPSEY, of the same
place, Foreman Hose Maker, do hereby declare the nature of this invention, and
in what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
This invention relates principally to the manufacture of what is known as india
rubber packing which is usually made from strips of canvas, about sixty feet long
and of a suitable width coated with india rubber and then rolled up by hand or
otherwise under pressure round an india rubber core; but the same apparatus is
also applicable to the manufacture of hose pipe from india-rubber-coated canvas
rolled round a metal core, which is afterwards forced out by hydraulic pressure;
and for other similar purposes where a strip of india-rubber-coated fabric is required
to be rolled up into a solid or tubular form.
The nature of our said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference to
the accompanying drawings and the following explanation thereof.
Fig. 1 on Sheet 1 of the drawings is a view of the driving end of our improved
machine and
Fig: 2-on Sheet 2 of the drawings is a front elevation of the two ends of the
machine which is more than sixty feet long and is composed of a suitable number
of sections each of which is a repetition of the one shown at Fig. 2.
The apparatus consists principally of a long table a (say about sixty two feet)
preferably faced with wood and supported at intervals upon suitable strong frame-
work b. The face of this table must be perfectly level and true from end to end.

page_text: Along the back of this table a there are fixed to the framing at suitable intervals
a series of arms or cranes c extending over the table a and carrying a long con-
tinuous shaft d upon which we fix a series of grooved pulleys e.
Over each of these pulleys passes a chain one end of which is attached to the
pulley e and the other end is attached to and supports a long iron box g, the lower
side of which is preferably faced with wood.
The lower face of this box g is made true with the upper face of the table a and
when the chains fare slackened the box will lie perfectly flat on the table a
touching the same from end to end.
Each end of this box g (which is made in sections bolted together) is fitted with
a set of parallel links and levers h, so that when it is raised up from the table a it
will always remain equidistant from it at all points, and if moved to and fro over
the table a it will always keep perfectly parallel.
The chain pulley shaft d is driven at one end by a worm wheel i at the driving
end actuated by a worm k fixed on one end of a short transverse shaft / receiving
motion through a countershaft m by means of bevil gear n and spur gear o from the
first driving shaft p which is fitted with two pulleys and two belts one of which is
crossed and the other open, so that by moving either belt onto the fast pulley by
the strap fork the gearing may be driven in either direction so as to raise or lower
the long box g.
7"
Each arm or crane c is provided above the table a with a racks capable of sliding
transversely through two bosses c¹ in the lower part of the crane so that they are
held and can move to and fro in a horizontal position above the table a.
The front end of each rack s has a hole bored vertically through it and through
this hole passes a pin t attached by lugs to the back of the long box y so that the
racks s can move the box g to and fro and at the same time the latter can be raised
and lowered whilst the racks s remain in a horizontal position.
26
Each racks is in gear with a toothed pinion and these pinions are all driven
by gearing from a long horizontal shaft v extending from end to end of the
machine, and actuated at the driving end by suitable spur gearing w from a second
main driving shaft x which (like the former one p) is also fitted with two pulleys
with open and crossed straps moved by a strap fork y, so that by moving this
latter in the proper direction by a hand lever or otherwise the long box 9 can be
caused to move transversely over the table in either direction.
The operation of making a sixty feet length of rolled packing by this apparatus
is as follows: A long strip of india-rubber-coated canvas of a suitable width
(according to the thickness of the roll required) is laid along the front of the
table a, and a corresponding length of india rubber core, coated with varnish is
laid along the back edge of the canvas which is then rolled once round the core
by hand.
g
The long box being in its most backward position (as shown at Fig. 1) the
chain pulley shaft d is first set in motion so as by means of the chains to raise
the long box g a certain height above the table a and the strap is then shifted onto
the loose pulley. The attendants then place the rolled edge of the canvas (with
the core inside it) just beneath the front edge of the long box from end to
end of the table a taking care that the canvas lies quite straight without puckers.
The chain pulley shaft d is now caused to revolve in the reverse direction so
as to lower the box g onto the rolled edge of the canvas and slacken the .
chains so that the weight of the box rests on the roll.
The pinion shaft is now set in motion so as to cause the racks s to push
the long boxy forwards (into the position shown in dotted lines at Fig. 1).
whereby the canvas is completely rolled up round the core, under pressure of
the whole-weight of the box, the latter acting in the same way as the box of
an ordinary domestic mangle.
The box is then raised
g
пр and the finished roll of packing can then be removed
being perfectly solid and cylindrical from end to end.

page_text: We prefer to make the strip of coated canvas of a number of pieces cut to an
angle of forty five degrees and jointed together edge to edge.
The operation of making a hose pipe or tube is the same, excepting that a
long steel mandrel is used instead of the core and is subsequently forced out by
hydraulic pressure in the usual manner.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
The general construction arrangement and operation of the improved apparatus
for the manufacture of india rubber packing, hose pipe, and other similar rolled
fabrics, substantially as hereinbefore described and illustrated by the drawings
annexed, and more especially we claim the use of the parallel links and levers
for the purpose of keeping the long box perfectly parallel and true to the table
as it is rolled to and fro.
