I WILLIAM BOWERY of No. 9 Weymouth Street, Apsley End Hemel Hempstead
Herts Card Maker do hereby declare the nature of this invention to be as follows
--
This improved machine consists of two or more cylinders of brass or other suitable
metal with a series of perforations in parallel lines running the whole length of the
cylinder. This cylinder has fixed in the inside of it a roll of wood or other suitable
material in which are graduated longitudinal grooves. These grooves are placed
opposite to and correspond with the perforations in the brass cylinder above
mentioned. Metal plates with perforations corresponding to the grooves in the
wooden roll are fixed to each end of the cylinders. These perforations and grooves
allow the air and water which accumulate in the process of manufacturing cards to
pass freely out at each end of the cylinders. These cylinders are covered with
clothing or felt. The bottom cylinder revolves in a trough containing paste or
other adhesive material and as it revolves carries the adhesive material to the cylinder
above it and by passing the paper of which the card boards are made, between the
cylinders at every alternate revolution the paste or other adhesive matter is equally
distributed on both sides of the paper of which the card is made.
The passing out freely from the machine of air and water and the equal distribu-
tion of the adhesive material are the principles I claim in my invention.
The machine is worked by means of four geared wheels and the upper cylinder
rises and falls by means of screws to adapt it to the thickness of the cardboard that is
being made by it. The upper cylinder also has a lever at each end of it to keep it
in position immediately above the lower cylinder which revolves in an ordinary
bearing.
The cylinders are covered with clothing which carries the adhesive material from
the trough beneath, already mentioned and the paper is carried through the machine
by means of silk threads which travel on rollers in the manner now in use in ordinary
card making machines.
Dated this 9th day of June 1887.

page_text: I WILLIAM BOWERY of No. 9 Weymouth Street Apsley End in the county of
Herts Card Maker, do hereby déclare the nature of my said 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 relates to apparatus for the manufacture of Ivory and Card boards and
paper of every description and for other purposes.
It is customary to make card of three or more layers viz. a core consisting of one
or more sheets of thick paper of inferior quality and two or more facing sheets or
outer layers of paper of superior quality. When card or cardboard is made in this
manner it is very desirable to prevent air and water or other liquid getting between
the clothing and the cylinder which causes the clothing to bulge and this creates
unequal pressure and prevents the paste or other adhesive substance from being
equally distributed over the surface of the cardboard or other material.
By my invention I prevent the accumulation of this air and water in the following
manner. I make a machine consisting of two or more cylinders or rolls of brass or
other suitable metal. This cylinder is shewn in elevation in Figure 1 in the accom-
panying drawing and in section on the line CD in Figure 2. These cylinders or rolls
are so constructed that at frequent intervals on their inner surface the metal of
which they are made is thicker as at g figure 2 than it is in the intervening spaces as
at and each of these increased thicknesses runs the entire length of the cylinder as
shewn by the dotted line from A to B. There is fastened to each end of the cylinder
(figure 2) a thick plate of the same or some other suitable metal and these plates
have attached to them the spindles on which the cylinder revolves. These plates are
shown in elevation in figure 3. and in section in figure 4 on the line E F. At eacli
of the before mentioned places (g) where the cylinder is enlarged or increased in
thickness on its inner surface I drill a hole (j) of suitable diameter the whole length
of the cylinder from A to B (hereinafter called "longitudinal holes") and on the
outer surface of each cylinder I drill holes (n. n. figure 1) at frequent intervals down
to and communicating with the longitudinal holes (j) already mentioned or I accom-
plish the same object with a perforated cylinder with an interior grooved wooden
roll. These holes or perforations (n. n.) allow the air and water or other liquid which
accumulate in the process of manufacturing card paper and other articles to pass
freely out through the longitudinal holes (.) at each end of the cylinder.
These cylinders or rolls are covered with clothing. One or more of them revolves
in a trough containing paste or other adhesive substance and as the material of which
the card paper or other article is being made passes between the cylinders.the before-
mentioned perforations in such cylinders or rolls allow the air and water or other
liquid which would otherwise get between the clothing and the cylinders to pass off
freely and by, so doing the cylinders have an even pressure on the substance passing
between them and they also equally distribute the paste or other adhesive material.

page_text: I also apply the principle of my invention to paper making by using the before
mentioned perforated cylinders for the purpose of dispersing air and water.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The freely passing off or dispersing of air and water or other liquid and the equal
distribution of the paste or other adhesive material in the manufacture of Card
Cardboard Paper and all other purposes to which my perforated cylinders are
applicable..
