IMPROVEMENTS IN PAPER MAKING MACHINERY
Year: 1846

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
WOODFULL, of Foots Cray, in the County of Kent, Paper Maker, 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 October, in the tenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the
said Henry Woodfull, my exors, adññiors, and assigns, Her especial license,
full power, sole privilege and authority, that I, the said Henry Woodfull,
my exors, admors, and assigns, and such others as I, the said Henry
Woodfull, my exors, adñiors, and assigns, should at any time agree with,
and no others, from time to time and at all times thereafter, during
the term of years therein expressed, should and lawfully might make, use,
exercise, and vend, within that part of Her said United Kingdom of Great
Britain and Ireland called England, Her Dominion of Wales, and the Town
of Berwick-upon-Tweed, in the Islands of Jersey, Guernsey, Alderney, Sark,
and Man, and also in all Her Majesty's Colonies and Plantations abroad, my
Invention of "IMPROVEMENTS IN PAPER MAKING MACHINERY;" in which said
Letters Patent is contained a proviso, that I, the said Henry Woodfull, shall
cause a particular description of the nature of my said Invention, and in

page_text: what manner the same is to be performed, under my hand and seal, to be
enrolled 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
Patent, as in and by the same, reference being thereunto had, will more fully
and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Henry Woodfull, do hereby declare that the nature of my said Invention con-
sists in certain arrangements and combinations of machinery whereby in paper
making the processes of drying the paper and cutting it into pieces of any
required widths are more speedily accomplished than heretofore; and I declare
that the manner in which the said Invention is performed is fully set forth in
the following description thereof, reference being had to the Drawings hereunto
annexed, that is to say :-
to
Figure 1 is a front elevation of a drying apparatus constructed according
my said Invention; and Figure 2, a plan of a portion thereof on the line
a, b, of Figure 1. A is a framework, in which are mounted horizontally six
double sets of revolving rollers F, Numbers I., II, III, IV., V., and VI.
Every set consists of two series of six rollers each, and the rollers of each
series are mounted one above the other, and alternate, as regards vertical
position, with those of the opposite series, so that every roller of each series
comes opposite a blank space in the next adjoining series of the same set,
which allows of the web of paper being carried alternately over and under the
two series of rollers in each set. Between every two sets of rollers there is
interposed a loose or vibratory roller, under or over which the web of paper
is carried; three of these rollers (I, I, I,) being placed at the top of the
apparatus, and the remaining two (I', I',) at the bottom. These vibratory
rollers rise and fall of their own weight, according as the paper is contracted
or lengthened in the course of drying, and from thus accommodating them-
selves to the varying state of the paper are called "accommodation
"dancing" rollers. Those which are marked I slide up and down in the slots
c, c, of the standards K, K, and those which are marked I' are supported by
oscillating levers L, L, which are counterpoised by weights M, M. R, R, are
picking or brushing rollers, placed so that the web of paper as it passes to or
from the "accommodation or "dancing" rollers I and I' shall come in con-
tact therewith, and be freed from any stray matters which may happen to attach
to it in its course through the drying frame. The whole of the rollers F, F,
and R, R, are put in motion by wheel-work fixed at the back of the apparatus
(not seen in the Drawing), and connected by cords, straps, or bands to pulleys
"
or

page_text: p.p, attached to the ends of the said rollers, the wheel-work deriving its motion
from the steam engine, or other primary power employed on the premises. H
is a heating chamber, constructed underneath the apartment in which the
drying apparatus is placed, and from which a constant supply of warm air
ascends through holes made for the purpose in the floor of the apartment, and
diffuses itself throughout the drying machinery. The chamber may have a
stove placed in it, or it may have warm air conveyed into it by pipes from some
other convenient source of supply. The horizontal rotary movements of the
various parts of the machinery assist to produce a continuous upward current
of warm air, and at the top of the apartinent there are apertures made in the
walls and roof, to allow of the escape of the used air into the external atmo-
sphere. B is a sizing machine of the ordinary description. The web of paper
as it comes from this machine is first passed over and under the two series of
rollers of the set No. I., then under the first of the "accommodation
"dancing" rollers I, and thence down between the rollers of the set No. II.
in the same alternating order as before, and so the operation goes on through-
out the entire series. From the drying apparatus the paper is immediately
carried under a series of circular cutters, marked O, O', Figures 3 and 4, which
divide it longitudinally into pieces of any required widths, and whence it is
passed on between the glazing rollers P, P.
"
ог
A modification of the preceding arrangements, in so far as regards the drying
parts of the machinery, is represented in the top portion of Figure 1 above the
line y, 2.
In this modification the rollers of each set have their bearings in
the opposite ends of balance or oscillating levers, similar to those marked L,
and before described, which renders the employment of separate "accommo-
dation" or "dancing" rollers unnecessary. Picking or brushing rollers are
introduced in the intervals in the same way as in the arrangement first before
described.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that the improvements which I
claim as constituting my said Invention are as follows:-
First, I claim the employment in paper making for the drying of the paper
of double sets ef rollers, mounted and revolving horizontally, and having
"accommodation " or "dancing" rollers, and picking and brushing rollers
interposed between every two of the said sets, as herein-before described.
Second, I claim the modification whereby the separate "accommodation
dancing" rollers are dispensed with, as herein-before described.

or
And, third, I claim the combination of the said drying apparatus, according

page_text: to either of the said forms of construction, with cutting rollers, whereby the
web of paper is immediately on its being dried, or coming from the drying
apparatus, cut into any required widths, as herein-before described.
In witness whereof, I, the said Henry Woodfull, have hereunto set my
hand and seal, this Third day of April, in the year of our Lord One
thousand eight hundred and forty-seven.
HENRY (L.S.) WOODFULL.
AND BE IT REMEMBERED, that on the Third day of April, in the
year of our Lord 1847, the aforesaid Henry Woodfull came before our said
Lady the Queen in Her Chancery, and acknowledged the Specification
aforesaid, and all and every thing therein contained and specified, in form
above written. And also the Specification aforesaid was stamped according
to the tenor of the Statute made for that purpose.
Enrolled the Third day of April, in the year of our Lord One thousand
eight hundred and forty-seven:
