AN IMPROVEMENT IN MACHINES FOR WAXING AND OILING PAPER
Year: 1885

page_text: We HENRY MASON of 24 Sutton Street. Commercial Road, Confectioner and
WALTER RAWLINGSON of 22 Collingwood Road High Cross, Tottenham Waxed
paper Maker, both in the County of Middlesex do hereby declare the nature of
our said invention for "AN IMPROVEMENT IN MACHINES FOR WAXING AND OILING
PAPER" to be as follows:-
Our Invention relates to an improvement in machines for waxing and oiling
paper having for its object to equalize the deposit and remove the superfluous wax
or oil, whereby the quality of the paper is improved and the cost of the production
reduced by the saving in wax or oil.
The invention consists in the construction and in the application to the machine
of a steam heated scraper or knife applied to act on the undersurface of the paper
immediately on leaving the hot pressing rolls through which it passes from the
bath.
This knife or scraper has a bevelled edge and is fitted to a steam pipe preferably
by letting the back of the knife into a longitudinal groove in the pipe which
extends the whole length of the knife and imparts heat to it by conduction. This
knife is made adjustable by means of screws or otherwise to regulate its action on
the paper and the superfluous wax removed by the knife, falls into a shoot by
which it is returned to the waxing bath.

We HENRY MASON of 24 Sutton Street, Commercial Road, Confectioner and
WALTER RAWLINGSON of 22 Collingwood Road, High Cross, Tottenham, Wax
paper maker, both in the County of Middlesex, do hereby declare the nature of
our invention for "AN IMPROVEMENT IN MACHINES FOR WAXING AND OILING
PAPER 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 improvement in machines for waxing and oiling
paper having for its object to equalize the deposit and remove the superfluous wax
or oil whereby the quality of the paper is improved and the cost of the production
reduced by the saving in wax or oil.
The invention consists in a steam heated scraper or knife applied to act on the
undersurface of the paper immediately on leaving the hot pressing rolls through
which it passes from the bath.
This knife or scraper has a bevelled edge and is fitted to a steam pipe preferably
by letting the back of the knife into a longitudinal groove or slot in the pipe which
extends the whole length of the knife and imparts heat to it by conduction. This
knife may be made adjustable by means of screws, or otherwise, to regulate_its
action on the paper, and the superfluous wax removed by the knife is returned to
the waxing bath.
Reference is to be had to the accompanying drawings forming part of this
Specification wherein Figure 1 is a cross section of the hot pressing rolls and steam
heated knife of our invention. Figure 2 is a plan of the same. Figure 3 is a cross
section of the steam heated knife on a larger scale, and Figure 4 is a side elevation
of the principal parts of the whole machine showing the compensating driving
gear for winding the paper up uniformly, part of which is shown in elevation in
Figure 1. The same letters of reference indicate the same parts in all the figures.
a. d. are the steam heated pressing rolls constructed and operating in the usual
manner. b is the waxing bath through which the paper drawn from the roll is led
in the usual way.
c is the steel scraper and d the steam pipe in which it is fixed.
This pipe is connected at the ends to pipes preferably of smaller diameter by which
a circulation of steam is maintained through the pipe d. e is the paper drawn over
the bevelled edge c³ of the knife which is adjusted at such a height above the bite
of the rolls a a as to deflect the paper slightly from the straight line and so scrape
it sufficiently to remove the superfluous wax or oil. After passing over the knife
the paper is wound on a roller f situated at such a distance from the knife as to
allow the wax or oil to cool before the paper is wound up, the paper being carried
to the roller without intermediate support.
This roller is driven by a crossed belt g, carried over a series of adjustable guide
pulleys whereby the tension of the belt can be diminished in order to allow the belt
to slip sufficiently to approximately compensate for the increase of diameter of the
paper roll on f and so equalize the passage of the paper through the machine.

page_text: Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed we declare that what
we claim is
The combination with a machine for waxing and oiling paper of a steam heated
scraper or knife applied to act on the underside of the waxed or oiled paper
immediately after it leaves the hot pressing rolls substantially in the manner and
for the purpose specified.
