Improvements in Machinery or Apparatus for Spreading Waterproof
or other Plastic Materials or Cements upon Fabrics.
We HENRY BIRLEY, Consulting Engineer of 54 Royal Exchange, and THOMAS
WILLIAMS Engineer to Messieurs Charles Macintosh and Company of Cambridge
Street Works, both of Manchester in the County of Lancaster do hereby declare the
nature of this invention to be as follows
--
In the ordinary machines for spreading waterproof or other plastic materials or
cements upon fabrics the spreaders or gauges are made suitable for spreading the
plastic material upon the full width of the fabric as it passes under them.
The object of this invention is to make a wide machine available for spreading the
plastic material simultaneously on two or more narrow widths of fabric avoiding the
waste of fabrics which occurs when this is done on the ordinary wide machines
owing to the narrow fabrics not being all of the same length and the impossibility
of drawing the ends of the shorter lengths of fabrics under the spreaders or gauges
at the parts where these are attached to the drag-cloths, as the thickness of the
attachment of the end of the fabric to the drag-cloth would prevent it from passing
under the gauge or spreader.
According to our invention each gauge or spreader is divided into two or more
lengths each of these lengths being suitable for the narrow fabric upon which the
plastic material is to be spread and each line of spreaders swings or oscillates upon
a spindle or arbor which passes through the whole line of spreaders or is otherwise
so arranged that each length can be raised from the fabric in the usual way (so that
each length of spreader can be used for each narrow width of cloth) independently of
the other.

Improvements in Machinery or Apparatus for Spreading Waterproof
or other Plastic Materials or Cements upon Fabrics.
We HENRY BIRLEY, Consulting Engineer of 54 Royal Exchange, and THOMAS
WILLIAMS, Engineer to Messieurs Charles Macintosh and Company of Cambridge
Street Works, both of Manchester in the County of Lancaster do hereby declare
the
manner
same is to be
the nature of this invention and in
performed, to be particularly described and ascertained in and by the following
statement:
what
In the ordinary machines for spreading waterproof or other plastic materials or
cements upon fabrics, the spreaders or gauges are made suitable for spreading the
plastic material upon the full width of the fabric as it passes under them.
The object of this invention is to make a wide machine available for spreading the
plastic material simultaneously ou two or more narrow widths of fabric, avoiding the
waste of fabric which occurs when this is done in the ordinary wide machines
owing to the narrow fabrics not being always of the same length and the impossibility
of drawing the ends of the shorter lengths of fabrics under the spreaders or gauges
at the parts where these are attached to the drag-cloths, as the thickness of the
attachment of the end of the fabric to the drag-cloth would prevent it from passing
under the gauge or spreader.
The nature of our invention and the manner in which the same is to be performed

page_text: or carried into practical effect will be readily understood on reference to the two
sheets of drawings hereunto annexed and the following explanation thereof.
Sheet 1. of the drawings represents a front elevation of a spreading machine
constructed according to our invention and Sheet 2 shows a side view of the same;
a being part of the frame of the machine b the bed roller, e, c' the gauge or spreader,
and d part of the steam chest, e, e¹ are the batch rollers for supplying the cloth
or fabric to be coated, and f, f' are the batch rollers for receiving the same after
coating.
According to our invention each gauge or spreader is divided into two or more
lengths (two lengths c and c¹ being shown on the drawings) each of these lengths
being suitable for the narrow fabric upon which the plastic material is to be spread
and cach length swings or oscillates upon a spindle or arbor which
the whole line of spreaders, or is otherwise so arranged that each length can be
passes through
raised from the fabric in the usual way (so that one length of the gauge or spreader
can be used for each narrow width of cloth) independently of the others.
Each width of cloth or fabric is provided with separate batch rollers of suitable
length and the latter are so arranged that they can be separately and independently
driven.
A rail is fixed across the machine behind the line of gauges or spreaders to
which are attached a bracket or brackets i provided with set screws k so that each
end of each length of spreader may be adjusted separately so as to regulate the
thickness of coating.
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 we
claim is :-
The improvements in machinery or apparatus for spreading waterproof or other
plastic materials or cements upon fabrics, substantially as hereinbefore described
and illustrated by the drawings annexed whereby we are enabled to make a wide
spreading machine available for spreading the plastic material on two or more narrow
widths of cloth simultaneously without waste of time or material.
