PROVISIONAL SPECIFICATION.
Improved Spreading Machine for Waterproofing Fabric with India
Rubber and other similar purposes.
WILLIAM LAWRENCE LIVERMORE 127 Mauldeth Road Fallowfield Manchester
Mechanical Engineer do hereby declare the nature of this invention to be as
follows: ×
The substitution of a moveable head-stock and guage for the fixed head-stock in
present use so that the cloth may be proofed, or spread, when travelling in either
dirrection thereby avoiding the loss of time consequent upon returning the cloth in
the old way or the cost of employing two head-stocks and two guages-one at either
end of the machine-for performing the same work.
The spreading machines in present use have-whether single or double-headed-
the guage or spreading knife, placed vertically above the roll between which and
the guage the cloth passes, but with my invention after the cloth has been proofed
on the forward travel with the guage in the usual position it can be proofed again
on the return by moving the guage forward on the roll to an angle of 30 degrees or
thereabout.

Improved Spreading Machine for Waterproofing Fabric with India
Rubber and other similar purposes.
WILLIAM LAWRENCE LIVERMORE 127 Mauldeth Road Fallowfield Manchester
Mechanical Engineer 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 concists in the substitution of a moveable head-stock and double
edged guage for the fixed head-stock and single guage hitherto used so that the
cloth may be proofed, or spread, when travelling in either dirrection thereby avoiding
the loss of time consequent upon returning the cloth in the old way or the cost of
employing two head-stocks and two guages-one at either end of the machine-for
performing the same work.
In carrying out my invention I employ a head-stock and guage which may be
used in a vertical position, feeding at the front, in the ordinary way, for the forward
travel of the cloth and moved forward to an angle of 30° or thereabouts, turning
back the guage so as to bring the second edge into position, feeding at the back,
for the return travel.
In this way the loss of time, occupied in winding back the cloth reversing the
rolls or transfering the opperation from one end of the machine to the other and
adjusting two distinct guages, is avoided.
In the accompanying drawing I have shown my improved machine in longi-
tudinal section and illusterated by dotted lines the travel of the cloth to be proofed,
or spread, in the backward and forward movement.
A is the roll of cloth which passing over the "back drum" F guide roll C feed-
roll D under the guage G at H and over the "back drum" E is taken up at B.
For the return travel the head-stock J is moved forward to K, turning on the
neck of the feed-roll D: the guage G is turned back so as to bring the edge I into
position against the roll D the spreading composition is fed in at the back against I

page_text: and the driving gear of the machine reversed returning the cloth from B over the
drum E under the guage at I over the roll D guide roll C and drum F to A,
repeating the opperation until the required number of layers have been spread upon
the cloth.
L, L, are the steam-heated tables or chests for drying the fabric and evaporating
the solvents, these chests may be placed as shown in the drawing or in any other
suitable position.
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 :-
(a) A moveable head-stock to allow of the cloth being spread while travelling in
either dirrection thereby dispensing with the necessity for employing two head-
stocks and two guages-one at either end of the machine.
(b) A double edged guage, or guage with two spreading knives, for distributing
the rubber compound evenly over the fabric in whichever dirrection the cloth is
travelling instead of the single edged, or single knife, guage hitherto used capable
of spreading the cloth as it travels in one dirrection only.
