COMPLETE SPECIFICATION.
Improved Apparatus for Supplying Paper and other Fabrics with
Paste and other Liquid Cementitious Matter.
We, JOSEPH FOSTER, FRANCIS FOSTER, and JAMES YATES FOSTER, all
of Bow Lane Iron Works, Preston, in the County of Lancaster, Engineers, 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:-
Our invention relates to an improved construction of apparatus for supplying
paste or other liquid cementitious matter to paper and other fabrics, whereby such
cementitious matter is supplied more abundantly and more perfectly to the paper
than with the arrangements heretofore employed for this purpose.
According to our invention we cause a constant and uniform supply of the
cementitious material to be delivered on to the paper from the suitable shaped
orifice of a tube through which the material is forced by a worm or other suitable
appliance from a reservoir containing the same, such reservoir and forcing appliance
being so arranged relatively to the level at which the orifice of the tube is situated
that when the forcing appliance ceases to operate no further quantity of liquid will
flow from the tube, and as soon as the forcing appliance is set in motion again, the
material will at once be delivered on to the paper.
For this purpose, according to the arrangement we prefer to employ, the
paste or other cementitious matter is contained in a tank situated at a lower
level than the surface of the paper or other material on to which the paste is
to be supplied, and the paste is raised by a pump, worm or otherwise to about
the same level as the said paper, where it is delivered into a tube by preference
of flexible material extending horizontally or nearly so to the paper and having
its orifice applied in more or less close proximity to the surface of the paper,
so that as this is made to travel along, the paste &c. will be delivered from
the orifice on to the paper in a line, the width of which will correspond to the
orifice of the tube, the quantity delivered being regulated on the one hand by the
speed of the forcing appliance and on the other hand by a regulating cock or valve
on the supply tube.
On the accompanying drawing is shewn by way of example an arrangement of
our improved apparatus combined with a newspaper printing machine for supplying
a line of paste to a continuous sheet of printed newspaper, in order that two sheets
may be secured together by pasting.
Fig. 1 shews an elevation, Fig. 2 is a plan and Fig. 3 is an end view of the orifice
of the delivery tube.
end of
A is a tank containing the paste or other cementitious matter to be applied to
the paper, and secured to any convenient part B of the printing machine. C is a
tube extending down into the tank and containing a worm D to the upper
whose axis is fixed a bevil pinion E gearing with another bevil pinion F on a shaft
carried by a bracket on the framing B and driven by a band and pulley G from
any convenient shaft of the machine, so as to impart rotary motion to the worm D
and thereby raise the paste up the tube C.
On the upper end of the latter is provided a branch H with cock I, to which is
attached a flexible tube J passing to a roller K round which travels the printed
paper L. The tube is there supported by a clip M adjustable on a standard N
and supporting a second clip O by means of a spring arm P which is so arranged
as to hold the orifice of the tube close against the paper L.
The clip O is formed as shewn at the end view at Fig. 3 so as to close the
opening of the tube all but a small hole through which the paste issues, the edge

page_text: of the tube being by preference formed with a notch below the hole so that the
width of this notch will determine the width of the line of paste applied to the
paper.
Thus it will be seen that the paste raised by the worm D will be delivered into
the tube J in quantity depending upon the speed of the worm and the degree of
opening of the cock I, and will be supplied by the tube to the paper in sufficient
quantity to insure the perfect adhesion thereto of a second sheet.
It will be evident that several tubes J could be connected to the worm tube C
for supplying paste to several sheets of paper; also, that the orifice of the tube J
might be applied to the flat part of the travelling paper, provided there be a
suitable fixed resisting surface behind the latter. The orifice of the tube J being
at the same level as the branch on the tube C, no paste will flow from the former
when the motion of the worm is stopped. The upper end of the worms axis is by
preference provided with a second worm of reversed pitch D' whereby the paste
will be prevented from being forced above the level of the branch H, and a space
is left between the two worms at the level of the branch for the delivery of the
paste into the latter.
The lower end of the worm D is by preference made to extend somewhat below
the end of the tube C, whereby it will be made to produce a circulating motion in
the paste in the tank so as to prevent it from settling. For the same purpose the
projecting end might have radially projecting screw vanes fixed to it.
The bracket Q carrying the tube Cmay be made vertically adjustable on the
framing so as to enable the degree of immersion of the tube C to be adjusted.
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 what
we claim is :-
--
1. In apparatus for supplying paper and other fabrics with paste and other
liquid cementitious matter, the combination with a reservoir for the cementitious
matter of a worm or other appliance for raising the liquid to a level above the
reservoir where it is delivered into a tube extending to the paper or other fabric
to be supplied, the orifice of the tube being held in close contiguity to the paper
so as to deliver the liquid thereon in a line of the required width, substantially as
described.
2. In apparatus for supplying paper and the like with cementitious matter, the
combination of a tube C containing a worm D and partly immersed in a tank A
containing the cementitious matter, gearing E F driven by a suitable motor for
imparting rotary motion to the worm, a branch H on the tube C provided with a
cock I a flexible tube J for conveying the cementitious matter to the paper, and
clips MO for holding the orifice of the tube against the paper L at or about the
same level as the branch H of the tube C, substantially as described.
3. In combination with the worm D, referred to in the preceding claims, a second
worm D' with reversed pitch for preventing the cementitious matter from being
raised above the level of the branch H, substantially as described.
