I, HERBERT JOHN HADDAN of 67 Strand in the County of Middlesex Civil
Engineer do hereby declare the nature of this invention, a communication to
me from abroad by George Edward Raymond of Chicago in the United States of
America, Manufacturer, 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 improvements in Apparatus for waxing paper or other
material.
The object is to provide means for coating to a greater or less thickness or
partially or completely saturating paper or other material with wax paraffine and
the like, by the capillary process and to further provide a simple effective and
economical apparatus for the above purpose.
With these ends in view my invention consists in certain features of construc-
tion and combinations of parts as will be hereinafter described and pointed out in
the claims.
The accompanying drawing represents the apparatus in vertical longitudinal
section.
A represents a tank in which the wax paraffine etc is kept in a liquid state by
heat from a series of steam radiator pipes B or by any other suitable means. From
the tank A a pipe a leads to a well C situated as low or lower than the tank A. in
order to cause the melted wax to flow freely from the tank thereto. The pipe a is
provided with a stop cock a¹ to regulate the flow of the melted wax. Over the
well C is a porous slab or series of slabs D of stone, wood, or other suitable material
kept at the desired temperature by a series of radiator pipes b which may con-
veniently be a continuation of the pipes B or may be a seperate series. Through a
slot in the slab D or through an opening between two of the slabs, a bunch of
wicking, felt or other fibrous or porous material E adapted to raise the wax by

is adapted to be raised or lowered by a pinion f on a rotary shaft, which meshes
with a series of teeth or notches f¹ on the tube. At a short distance from the
tube e there is a second opening in the slab D or between the slabs, through which
a second bunch or block of wicking felt or the like E¹ projects. The lower end of
the wicking E' does not, however, extend to the surface of the melted wax in the
well and is employed as a return conduit as will hereinafter appear. G represents
the paper.
It is drawn from a reel H over a pair of rollers I and beneath a
pressure roller i, the rollers I are synchronously geared and the roller i is driven
by its frictional contact with the roller I. and the tension of the paper is regulated
thereby. From the rollers I, i, the paper extends up and over the face or faces of
the slab or slabs D. over the top of the wicking E and thence along the face or
faces of the slab or slabs D over the top of the wicking El thence to the set of
rollers K, k, similar to and geared in the same manner as the rollers. I, i, thence
into the receptacle L and thence through a set of rollers M, m, to the cutter N.
The cutter or cutters N. consist essentially of a drop knife or rotary cutter or
cutters operated by a wheel O. geared with the roller M, m, which by a series of
cams or other equivalent means alternately engages' and releases a lever P.attached
to the drop knife.
The paper as it passes over the slabs is kept heated by heat from the slabs, and
is hottest on the side which is to receive the wax. As it passes over the top of the
wicking E it is covered with wax drawn up from the well C by the wicking,
felt, etc. As it passes along over the slabs after leaving the wicking E any super-
fluous wax is removed by the second set of wicking E¹ the wax being returned
through said wicking into the well.
The pressure of the wicking in the tube e is regulated by raising or lowering
the tube, and the waxed surface may be operated upon by two or more bunches of
wicks or felt E' instead of one. The same arrangement might also be employed
above the paper for coating the upper side as well as the lower."
It is evident that slight changes might be resorted to in the form and arrange-
ment of the several parts described without departing from the spirit and scope of
my invention, hence I do not wish to limit myself strictly to the construction
herein set forth.
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. In apparatus for waxing. paper the combination with a porous slab or slabs
over which the paper is drawn of a bunch of capillary tubes leading from a
reservoir beneath the said porous slab or slabs up through the same into contact
with the paper substantially as set forth.
2. In apparatus for waxing paper, the combination with a porous slab or slabs
and means for keeping them at the desired temperature of a vertically adjustable
bunch of capillary tubes leading from a well beneath the slab or slabs to a joint
above their upper surface, substantially as set forth.
3. In apparatus for waxing paper, the combination with a porous slab or slabs
and means for heating the same of a bunch of felt or other suitable material
adapted to feed the wax up through an opening in the slab or between the slabs,
and a bunch of capillary tubes adapted to convey the superfluous wax down
through an opening in the slab or slabs, substantially as set forth.
4. In apparatus for waxing paper, the combination with one or more slabs of
porous material, such as soap-stone pumice stone, and the like, and means for
passing paper over their surfaces, of a bunch of capillary tubes enclosed within a
casing, and a pinion and a series of notches for adjusting the casing and hence
the capillary tubes, substantially as set forth.

lower than the tank, and a pipe leading from the tank to the well and provided
with a stop-cock, of the porous slab or slabs located over the well, the bunch of
capillary tubes leading from the well through the slab or slabs, and the several sets
of rollers adapted to regulate the movement of the paper over the slab or slabs,
substantially as set forth.
6. The combination with the waxing apparatus, substantially as described of the
cutter or cutters located and operated substantialy as set forth,
