IMPROVEMENTS IN PRESSING TALLOW AND OTHER MATTERS AND SUBSTANCES AND FABRICS
Year: 1845

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
PALMER, of Sutton Street, Clerkenwell, in the County of Middlesex, Manu-
facturer, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Third day of March, in the eighth year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto me, the said
William Palmer, Her especial licence, full power, sole privilege and authority'
that I, the said William Palmer, my exors, adñiors, and assigns, or such
others as I, the said William Palmer, my exors, admors, or assigns, should
at any time agree with, and no others, from time to time and at all times
during the term of years therein expressed, should and lawfully might make,
use, exercise, and vend, within England, Wales, and the Town of Berwick-
upon-Tweed, my Invention of "IMPROVEMENTS IN PRESSING TALLOW AND OTHER
MATTERS AND SUBSTANCES AND FABRICS;" in which said Letters Patent is
contained a proviso that I, the said William Palmer, shall cause a particular
description of the nature of my said Invention, and in what manner the
same is to be performed, to be inrolled in Her said Majesty's High Court
of Chancery within six calendar months next and immediately after the date
of the said in part recited Letters l'atent, as in and by the same, referenco
being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
William Palmer, do hereby declare that the nature of my said Invention,
and the manner in which the same is to be performed, are fully described
and ascertained in and by the following statement thereof, reference being

page_text: had to the Drawings hereunto annexed, and to the figures and letters
marked thereon (that is to say):-
My Invention consists in arranging continuous surfaces in such manner
that matters requiring to be pressed are continuously fed in at one end of the
machine and continuously delivered at the other end of the machine, and the
pressure is gradually encreasing on the matters subjected thereto from the
time of their entering the machine to the time of their leaving the machine.
And in order that my Invention may be most fully understood and readily
carried into eflect, I will proceed to describe the means pursued by me.
DESCRIPTION OF THE DRAWINGS.
Figure 1 represents a longitudinal section of a machine for pressing
arranged according to my Invention; Figure 2 is a transverse section thereof;
in each of these Figures the same letters are used to indicate similar parts.
a, b, are two rollers suitably arranged for moving the endless chains c, c, such
chains being moved by indents in the roller a, in which the axes c' of the links
of the endless chain takes. The endless chain c, c, has bars of hard wood or
other suitable material d, d, fixed across it, and these bars are the pressing
surfaces or instruments aided by another arrangement of surfaces carried by
other endless chains hereafter described. c, f, are cylinders which receive the
endless chains 9.9 the cylinder e being similar to the roller a, with indents
to receive the axis of the chain g, and this chain is similar to that at c, c, and
motion is given to the cylinders a and c in the following manner-On the
axes of the cylinders a and c are affixed cog wheels a' and e', the cog wheel a¹
taking the cog wheel e¹ causes those cylinders to travel together. The cog'
wheel a' is taken into and driven by the pinion A on the axis B, on which are
affixed a fast and loose pulley, motion to which may be given by a band driven
by a steam engine or other suitable power. The endless chains J., carry
metal plates-g', ', which are turned up at right angles at their ends, as is
shown. On the chain of surfaces carried by the chains g, g, is an endless
apron h, h, of strong canvas or other suitable material, and it is on this
surface or apron that tallow or other fatty matters are spread at i, i, in order to
their being pressed; and in order to prevent the tallow or other matter being
driven back, have cloths i, j, of thin canvas or other suitable material
affixed across the endless apron at intervals, and further cloths at k, k, at
the sides of the endless apron, so that when tallow or other fatty matter has
Leen spread at i, i, the cloths j, j, are laid over the same, and then the cloths
k, k, on either side, and in this state the tallow or other fatty matter is carried
between the pressing surfaces hereafter described, and the fatty matter on its

page_text: arrival at the end is to have the cloths j,j, and k, k, removed, and then the
concrete fatty matter is to be. taken off the endless apron h, h. m, m, are
two endless chains of pressing rollers ?, n, between which the endless chains
of surface before described pass, and the matter between them is com-
pressed. o, p, are two planks, the lower one p of which is fixed, and the
upper one is capable of adjustment by screws 9; and it is important to call
attention to the circumstance that the planks o, p, are further apart at the end
of the machine where the matters to be pressed enter, and they approach each
other so as to come nearer together at the point where the pressure ceases;
hence it will be understood that the matters being pressed are gradually more
and more pressed from the point where the pressure commences to the point
where the pressure ceases, and the matter under process of pressure will
be subject to pressure for a considerable time, and although the pressure
will be similar in some respects to that of a pair of rollers, there will
be the material difference of the extent of moving pressure to which the
matter is subjected by this arrangement of machinery. The endless chain of
surfaces 9 may if desired, be supported on the under side by rollers v. v,
as shewn. The upper rollers n, n, are supported by the platform s, s. This
machinery, when for pressing tallow or other fatty matters, is to be placed in a
room, the floor of which is to be covered with lead, so that the fluid portion of
the fatty matters expressed from the more solid or concrete parts may fall to
the floor and flow away by suitable gutters or channels on the floor into
suitable receivers. This machinery is also suitable for pressing matters which
do not require the cloths j, as wet grains, hops, &c. from the brewers, and the
machine is also suitable for pressing wet woollen or other fabrics to extract
the moisture therefrom, in which case the folded pieces would be placed
successively at i, i, on the travelling endless apron, and they will be delivered
pressed at.
Having thus described the nature of my Invention, and the best means I
am acquainted with for performing the same, I would have it understood
that I do not claim any of the parts separately, nor do I confine myself to the
details, so long as the peculiar character of the Invention be retained. But
what I claim is, the mode of arranging machinery for pressing tallow and other
matters and fabrics as herein described.
In witness whereof, I, the said William Palmer, have hereunto set
my hand and seal, this Second day of September, in the year of
our Lord One thousand eight hundred and forty-five.
W (L.S.) PALMER.
