I, WILLIAM COULTER of Huntingdon Street, Eagle Street Chorlton-on-Medlock,
Manchester in the County of Lancaster Superintendent Spreader do hereby declare
the nature of my invention for IMPROVEMENTS IN MACHINES FOR SPREADING
INDIA RUBBER OR OTHER SIMILAR MATERIALS UPON FABRICS to be as follows:―
The improvements which are the subject of this invention relate to the form and
construction of machines or appliances used for spreading India rubber or other
similar material upon fabrics, and consist in an arrangement of parts so as to form
a double ended machine with reversible motion, whereby the operator is enabled to
work from, and feed the said machine at either end, while dispensing with the
necessity of the pieces. being either wound back or lifted out and turned round
when they require to be recoated and reversed, also any defect in one roller is
neutralized by the reverse coat applied by the opposite roller.
In spreading machines that have hitherto been constructed, the dough is fed at
one end only, and work in one direction only. The usual process is to pass the
fabric over a roller and under a gauge for regulating the thickness of coating, the
operator standing at the front feeding the machine with dough. The material then
passes over a steam chest or heater and also over an adhesive drum at back of
machine which draws the piece along, and it is then wound up under the machine
when the operator has to either wind the piece back or lift it out and turn it
round for recoating. In these machines the driving drum which is also an adhesive
drum is placed at back of machine and behind the spreading roller.
In this invention I construct a double ended spreading machine which is a
machine with the parts arranged so that the operator is enabled to work at either
end of the said machine for the purpose of obviating the necessity of either winding
the piece back or of having to lift the pieces out, and turn them round for recoating
and reversing and also for allowing the operator the option of working from
that end of the machine in the direction from which the noxious vapours are
carried by the draught, which sometimes arise from certain classes of material
used: the operator by this means escapes the poisonous effects of the said vapours.
To suitable frames I attach a roller and gauge. These rollers work in reverse
directions. Between these rollers I place a steam chest or heater with the surface
on a level with the upper surface of the rollers. At each end or front of the

page_text: machine, I place a driving drum. The gauge at the end opposite to that at which
the operator stands being raised the operator supplies the dough at one end through
the roller and gauge onto the texture for the purpose of spreading one coat. The
fabric then passes over the steam chest or heater and over the driving drum at the
opposite end of machine and from thence passes to and is wound on the box under
the machine.
After the first coating the operator proceeds to the opposite end of the machine
and reversing the motion supplies the dough for the second or reverse coat from
that end. This mode of operations is repeated alternately from each end of the
machine until completion for any number of single coats in body or surface. The
piece after being attached to the boxes under machine not requiring to be removed
until completed.
In lieu of the material hitherto employed for the face or surface of the adhesive
drums which is liable to fire and decompose, I form these drums of metal either
for use as a steam drum or cylinder or of indented or perforated metal.
By these means friction is reduced and the liability of firing with consequent
injury to the rollers considerably lessened.
When the driving drum is out of gear and running in opposite directions, by
the machine being reversed the drums can be weighted for tension in the texture,
in place of putting the weights on the piece which is detrimental to the face or
surface.
Motion is given to the machine in alternate directions by a combination of straps
and gearing.

In securing the gauge in its position on the frame, I use a lock nut in addition
to the set screws to ensure greater accuracy in the gauge.

I, WILLIAM COULTER of Huntingdon Street Eagle Street, Chorlton-on-Medlock
Manchester, in the County of Lancaster Superintendent Spreader do hereby declare
the nature of my invention for IMPROVEMENTS IN MACHINES FOR SPREADING
INDIA RUBBER, OR OTHER SIMILAR MATERIALS UPON FABRICS, 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 the form and construction of machines, or apparatus,
used for spreading India rubber, or other similar material, upon fabrics, and consists
in an arrangement of parts, so as to form a double ended machine, with a reversible
motion, whereby the operator is enabled to work from, and feed the said machine
at either end, while dispensing with the necessity of the pieces being either wound
back, or lifted out, and turned round, when they require to be recoated and reversed,
also any defect in one roller is neutralized by the reverse coat applied by the
opposite roller.
In spreading machines that have hitherto been constructed, the dough is fed at
one end only, and work in one direction only.
The usual process is to pass the fabric over a roller, and under a gauge, for
regulating the thickness of coating, the operator standing at the front, feeding the
machine with dough: The material then passes over a steam chest, or heater, and
also over an adhesive drum at back of the machine, which draws the piece along,
and it is then wound up under the machine, when the operator has either to wind
the piece back, or lift it out, and turn it round, for recoating: in these machines,
the driving drum, which is also an adhesive drum, is placed at back of machine,
and behind the spreading roller. :
In this invention, I construct a double ended spreading machine, which is a
machine with the parts arranged, so that the operator is enabled to work at either
end of the said machine, for the purpose of obviating the necessity of either
winding the piece back, or of having to lift the piece out, and turn it round for
recoating and reversing, and also for allowing the operator the option of working
from that end of the machine in the direction from which the noxious vapours are
carried by the draught, which sometimes arise from certain classes of material
used: the operator by these means escapes the poisonous effects of the said
vapours.
:
In the construction of machines according to this invention I attach to suitable
frames, a roller and gauge, each roller and gauge spreading a coat in a reverse
direction: I place longitudinally, between these rollers a steam chest, or heater,
with the upper surface on a level, or nearly on a level, with the upper surface of
the rollers: At each end or front of the machine I place a driving drum.
The gauge at the end opposite to that at which the operator stands being
raised, the operator supplies the dough at one end through the roller and gauge, on
to the texture, for the purpose of spreading one coat: the fabric then passes over
the steam chest or heater, and over the driving drum at the opposite end of

page_text: the machine, and from thence passes to, and is wound on the box under the
machine After the first coating, the operator proceeds to the opposite end of the
machine, and reversing the motion, supplies the dough for the second, or reverse
coat, from that end: This mode of operations is repeated alternately from each
end of the machine, until completion, for any number of single coats, in body or
surface: The pieces after being attached to the boxes under machine, do not
require to be removed until completion:
In lieu of the material hitherto employed to form the face, or surface of the
adhesive drums, which is liable to fire and decompose, I prefer to use metal drums,
constructed so as to form a steam drum, or cylinder, or of indented or perforated
metal by these means, electricity is reduced and the liability of firing, with con-
sequent injury to the rollers is considerably lessened.
In securing the gauge in its position on the frame, I employ a lock nut in
addition to the set screws now in use, to insure greater accuracy in the gauge.
When the driving drum is out of gear, and running in opposite directions, by
the machine being reversed, the drums can be weighted for tension in the texture,
in place of putting the weights on the pieces, when wound on the boxes, which is
detrimental to the face or surface.
Motion is given to the machine in alternate directions, by a combination of straps
and gearing.
In order that my invention may be fully understood, I now describe the accom-
panying sheets of drawings: In the several views illustrated therein, similar letters
refer to similar parts.
Fig. 1 represents side view Fig. 2 is plan, and Fig. 3 end view of a double ended
spreading machine, constructed according to this invention.
The frames a¹ and a³, with the rollers and appliances contained therein, and which
are hereinafter described, are duplicates of each other, but are placed in reversed
positions, and form opposite ends of the same machine: the frame a placed in a
central position, forms part of the said machine, and contains the rollers or boxes
for receiving the fabric in process of manufacture, or when finished: The box g³
containing piece with conveying wrappers and at each end, is placed in position
at a. The leading wrapper is carried over the machine in the direction of arrow,
and attached to roller g¹.
The driving drum e having been placed out of gear, by means of the toothed
wheel being drawn forward on key bed of shaft 3 as shown in Fig. 3, and the
gauge c¹ having been raised the fabric represented by dotted line 7 is received from
box g³, passes over the driving drum e, over spreading roller b, under gauge c,
where the dough is supplied, over the conveying roller c and over steam chest or
heater d, in the direction indicated by arrow: the fabric then passes over
spreading roller b¹, round the driving drum e¹, in gear, and is wound on to receiving
roller g¹ placed in the central portion a of the frame.
After the first coating the operator removes box g³, attaches the bottom wrapper /
to the roller g, thus making the piece endless, raises the gauge c, gears up the
driving drum e, and proceeding to the opposite end of the machine, sets the
gauge c¹, places the driving drum e¹ out of gear, reverses the motion by means of
the clutch y or y¹, and supplies the dough for the second or reverse coat, the fabric /
returning over the steam chest or heater d, in the direction indicated by dotted
arrow the drums e and e¹ are weighted when running out of gear by means of
tension on the bands or straps to and to.
By shortening cross straps p¹and p² and placing them direct on g and g', the
pieces may be wound without the intervention of friction rollers f and f¹ g and g¹
being raised by means of set pins placed across groove kat k¹.
The driving drums e and e¹ are actuated by tooth wheels t and t¹, and the
spreading rollers b and b' by the toothed wheels 8 and 8¹ respectively gearing in
to the toothed wheels and 1 placed on shafts u and u¹, to which are attached
pulleys q and q¹.
These pulleys are connected by the belt or strap p.

page_text: Motion is given to the machine by the alternate use of the driving pulleys w
and which are caused to work in the required direction by means of straight and
cross straps, or gearing, and the clutches y and y¹.
The pieces are wound on the boxes g and g¹ by the action of the friction rollers f
and f¹ worked from pulleys u and us on shafts u and u¹, by means of the cross
straps p¹ and p².
When preferred, the texture may pass from box g³ over roller g³ and under scrape
gauge in lieu of passing from box g³ on to the driving drum e.
When the piece is finished it is rewound on to box g³ by a pinion ** being
slipped on to spindle of box g³, and gearing into pinion s attached. to frame, and
worked by the wheel't'.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is,
1st A spreading machine that is constructed for the purpose of spreading India
rubber or other similar material upon fabrics, arranged so that the spreading rollers,
and spreaders, are placed, and may be worked at either end of the said machine,
by a reversible motion, so as to apply to the fabric the required number of single
coats in reverse directions, in body or surface, without having to remove the pieces
until completion from the rollers or boxes to which they are attached, substantially
as herein before described and illustrated.
2nd A combination of parts, either arranged as herein before described, or other-
wise placed so as to form a double ended spreading machine, to enable the operator
to work at either end of the said machine, for the purpose of coating fabrics
reversibly with India rubber or other similar materials, without requiring to
remove the piece until completion.
3rd The combination of a reversible motion, with a double ended spreading
machine, for causing the fabric to pass backwards and forwards, during the process
of coating.
4th In a spreading machine, the application when preferred, of a steam drum or
cylinder formed of sheet metal, or of indented or perforated metal, in lieu of
India rubber varnish hitherto employed as an adhesive surface on wooden drums.
