COMPLETE SPECIFICATION.
Improvements in Spreading Machines for Spreading India Rubber
or other Plastic Materials on Textile Fabrics and the like.
We, WILLIAM COULTER of Park Street, Greenheys, Practical Waterproofer,
and THOMAS ROWLEY of Corporation Street, Consulting India Rubber Manu-
facturer and Rubber Expert, both in Manchester in the County of Lancaster
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 improvements which are the subject of this invention relate to machines that
are used for spreading india rubber or other plastic materials on textile fabrics and
the like, and the object of this invention is to enable gauges of different angles
with blunt or sharp edges, to be employed as scrapers for regulating the thickness
of coating without requiring the removal of either of said gauges from the machine
in order to place a gauge of the required angle in position.
We attain this object by mechanism illustrated in the accompanying sheets of
drawings and as hereinafter described.
In the drawings similar letters refer to similar parts.
In this invention in lien of the ordinary gauge which is or may be placed at
either or both ends or other equivalent position in a spreading machine such as
hereinbefore described, we employ gauges that form part of, or are attached to, a
frame that is capable of being revolved as represented in Figs. 1 and 2 on
drawings, which are side and end views respectively of gauges constructed
according to this invention applied to one end of a spreading machine.
In these views the gauges c, c¹ and c² which are each formed with different
angles, are attached to a frame by bolts, set screws, or other preferred means.
We support the frame either by a shaft passing through or spindles connected
to the ends of said frame; the ends e of said shaft or spindles have a bearing in a
box of the usual description placed in each side frame a and regulated in the
ordinary manner by means of the screws y, g'. We connect the ears j, j to the
frame by forming a dovetailed groove in said frame and placing therein counter-
sunk bolts with thumb serewsk' attached thereto as shown in Figs. 3 and 4, by
which means the said ears are placed and retained at any required distance apart.
In the accompanying drawings
Fig. 3 is a sectional view showing the hereinbefore described frame with the
gauge in proximity to the spreading roller m, and the ear j in the ordinary
position but attached to the frame by the bolt which is retained in the dove-
tailed groove h.
is
When it is desired to change the gauge c' for a gauge of a more or less acute
angle such as c or c² the aforesaid ears j and j' are detached and the frame
revolved by means of the handles a' and a² so as to bring the required gauge into
the position occupied by, and take the place of the gauge cl which is placed out of
the way by said frame being revolved; the gauge that has been brought into use is
adjusted by the screws g, g, and the ears j and corresponding with the angle are
replaced in the manner herein before described.
In the drawings annexed, to which reference has herein before been made we
have shown the revolving frame with three gauges attached thereto, but the form
of said frame may be varied so as to have a greater or less number of gauges
connected therewith.
The aforesaid gauges may be connected to the frame by means of grooved
backs as shown in Fig. 3.

page_text: Having now particularly described and ascertained the nature of this our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
In a machine that is used for spreading india rubber or other plastic materials on
textile fabrics and the like, the use of gauges of different angles, with blunt or
sharp edges or rounded faces such as c, c' and c² that may be employed as scrapers
for regulating the thickness of coating attached to a frame such as 6 which is
capable of being revolved so as to bring any one gauge of a required angle into use
without removing from the machine the gauges that are not required for immediate
use, in the manner substantially as herein before described.
Dated this 16th day of February 1892.
