PROVISIONAL SPECIFICATION.
Improvements in Machinery or Apparatus for Coating Paper or
other Fabric with Glue, Gum, Paste, or other Fluid or Semi-fluid
Material.
I, GEORGE ISAAC FELDON, of Upper Marsh, Lambeth, in the County of Surrey,
Drapers' Box Manufacturer, do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to construct a simple apparatus by the aid of which
fluid or semi-fluid matter, such as, gum, glue or paste, may be expeditiously and
economically applied to the surface of sheets or continuous lengths of paper or other
fabric.
For this purpose I employ a drum or cylinder fixed upon a shaft mounted with
capability of revolving in suitable bearings and 1 immerse the periphery of this drum
or cylinder at one part thereof in a bath of the coating inaterial.
The fabric to be coated is drawn across the drum or cylinder from botween a pair
of nipping or tension rollers which are preferably covered with India rubber or other
suitable material in order that they may obtain a proper grip of the fabric, and one
or both of these nipping or tension rollers is or are geared with the shaft of the drum
or cylinder thus giving motion theret in the direction of travel of the paper.
One of these nipping or tension rollers is preferably driven by contact with the
other or the fabric passing between them, the necessary nip being obtained by means
of weighted levers or springs acting to press one of such rollers upon the other. Or
one or both of the nipping or tension rollers may be driven from any suitable source
of power and motion may be communicated therefrom to the drum or cylinder or the
drum or cylinder may be so driven and motion may be communicated therefrom by
gearing to the nipping roller or rollers.
•
The surplus coating material is removed from the drum or cylinder by means of a
brush or doctor.
The action of this apparatus is as follows:-the drum or cylinder in its revolution
takes up a film of coating material from the bath and the surplus thereof is removed
by the brush or doctor, and the drum or cylinder continues to revolve bringing the
reduced film of coating material into contact with the fabric which is drawn from the
nipping or tension rollers across the surface of the drum or cylinder in the direction
of the revolution thereof thus evenly and efficiently covering the surface of the fabric
with the coating material.

Improvements in Machinery or Apparatus for Coating Paper or
other Fabric with Glue, Gum, Paste, or other Fluid or Semi-fluid
Material.
I, GEORGE ISAAC. FELDON, of Upper Marsh, Lambeth, in the County of Surrey,
Drapers Box Manufacturer, 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 object of my invention is to construct a simple apparatus by the aid of which,
fluid or semi-fluid matter, such as gum, glue, or paste may be expeditiously and

page_text: with such drum or cylinder thus as the fabric is drawn forward giving motion
thereto in the direction of travel of the fabric under treatment, and, if desired, both
of the nipping or tension rollers d d¹ may be geared together so that they both
impart a positive motion to the drum or cylinder c.
The nipping or tension rollers d d' are driven by frictional contact with the fabric
passing between them and the necessary nip is obtained preferably by the simple
weight of the upper roller d or the weight of this roller may be increased by loading
it with heavy metal if desired. The bearings of the shaft or axis d² of the nipping
or tension roller d are slightly elongated or slotted in order to allow such roller to
rest upon the fabric under treatment.
The surplus coating material is removed from the drum or cylinder c by means of
an adjustable doctor y formed of India rubber or other suitable material or it might
be a brush fixed to plates g¹ slotted to receive set screws g² screwing into the body or
frame a.
The action of the apparatus is as follows:-the fabric is drawn from the reel e
between the nipping or tension rollers d d'and across the drum or cylinder c thus
giving motion to the nipping or tension rollers and through the toothed wheels d
and c to the drum or cylinder c.
The drum or cylinder e in its revolution takes up a film of coating material from
the bath the surplus thereof being removed by the doctor g and the drum or
cylinder c continues to revolve' bringing the reduced film of coating material into
contact with the fabric which is travelling in the direction of the revolution of the
drum or cylinder thus evenly and efficiently covering the surface of the fabric with
the coating material.
Since filing my provisional specification, I have discovered that the arrangement
therein proposed for giving motion from a separate source of power to the axle of
the drum or cylinder or to the axle of one of the nipping or tension rollers does not
possess sufficient novelty or utility to render it advisable to make any claim thereto,
and I have therefore omitted any further description of, and, I do hereby disclaim
such arrangement.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, 1 declare that what
1 claim is
1. The improvements in machinery or apparatus for coating paper or other fabric
with fluid or semi-fluid matèrial, substantially as herein shown and described.
2. In machinery or apparatus for coating paper or other fabric with fluid or semi-
fluid material, a bath b to contain the coating material, a drum or cylinder c adapted
to revolve in such material and convey it to the fabric, a doctor g to remove the
surplus material and nipping or tension rollers d d¹ connected with the cylinder c by
gearing such as d c² thus giving motion by the forward movement of the fabric to
the drum or cylinder c, all in manner substantially as herein shown and described and
for the purpose stated.
3. In machinery or apparatus for coating paper or other fabric with fluid or semi-
fluid material, a bath b to contain the coating material, a drum or cylinder c adapted
to revolve in such material and convey it to the fabric, a doctor g to remove the
surplus material, and nipping or tension rollers d d pressed together by the weight
of the upper one d and connected with the drum or cylinder c by gearing such as d³ c²
thus giving motion by the forward movement of the fabric to such drum or cylinder c,
all in manner substantially as herein shown and described and for the purpose stated.
