PROVISIONAL SPECIFICATION.
Improvements in or Connected with Machinery for Varnishing and
otherwise Coating Continuous Paper or other Material.
I, EDMUND BUSII, of Hunslet Road, Leeds, in the County of York, Engineer,
do hereby declare the nature of this invention to be as follows:-
The object of this invention is to construct simple and compact machinery
for varnishing and otherwise coating continuous paper or other material, the
varnish or other coating being more evenly and efficiently applied than with
machines hitherto employed for the same purpose.
According to my invention, I employ a frame carrying a cylinder having a
plain unbroken surface, and on one end of the frame two brackets are provided
for the purpose of holding the roll of paper to be coated. Between the brackets
and the cylinder two guide rollers are provided, a tension roller actuated
by suitable springs or weights being situated between the said guide rollers, in
such a manner that the paper to be coated is held taut during its passage. from
the roller to the cylinder. A. varnish trough is situated at the front of the
machine, and an idle roller transfers the varnish from a roller in the trough to
the surface of the paper, the said idle roller pressing the paper against a blanket
on the cylinder. A roller or other delivery apparatus is provided at the back of
the machine for the purpose of taking off the coated web as it leaves the machine.

Improvements in or Connected with Machinery for Varnishing and
otherwise Coating Continuous Paper or other Material.
I, EDMUND BUSH, of Hunslet Road, Leeds, in the County of York, 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:-
The object of this invention is to construct simple and compact machinery
for varnishing, and otherwise coating continuous paper or other material, the
varnish or other coating being more evenly and efficiently applied than with
machines hitherto employed for the same purpose.

page_text: In order that my invention may be clearly understood, I will proceed to describe
the same with reference to the accompanying drawing which is a sectional side
elevation of a machine constructed according to my invention, and in which
letters of reference indicate the various parts.
A is the framework of the machine carrying a cylinder B having a plain
unbroken surface, and C, C are two brackets carrying suitable bearings at their
outer ends for the purpose of supporting a roll D of paper to be coated. E and F
are two guide rollers over which the paper to be coated is fed, and G is a tension
roller which may either be stationary as shewn, or which may be actuated by
springs or weights and so keep a constant tension on the paper. H is a varnish
trough situated at the front of the machine, and K is an idle roller which trans-
fers the varnish from a roller L rotating in the trough H, to the surface of the
paper carried on the cylinder B.
M is a
spreading roller and N is an auxiliary
spreading roller either of which are used according to the direction of feed of the
machine. P is a guide roller for assisting in taking off the paper after it has
received its coating of varnish. S is the main shaft of the machine through the
medium of which the cylinder B and the various varnishing and other rollers
are driven at an equal surface speed, with the exception of the roller M which
is driven at a much higher surface speed so as to cause it to spread the varnish or
other coat by rotating quickly on the coated surface.
If it is desired to run the machine in the opposite direction, the paper to be
coated would be fed from the roll D round the guide and tension rollers F, G
and E, and thence up round the cylinder B to the coating roller K from whence
it descends under the swiftly rotating roller N which equalizes and spreads the
varnish prior to the removal of the coated paper from the machine.
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:-
1. The combination of the cylinder B, guide rollers E and F, tension roller G,
coating roller K and spreading roller M, substantially as and for the purposes
set forth.
2. The combination of the cylinder B, brackets C, C, roll D, guide rollers E
and F, tension roller G, varnish trough H, rollers L and K, and spreading
rollers M and N, substantially as and for the purposes set forth.
3. The general arrangement, construction and combination of the various
parts forming the machinery for varnishing and otherwise coating continuous
paper or other material, substantially as described with reference to the accom-
panying drawing.
