UCKS SPECIFI ATION
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HEYCOCK, of Leeds, in the County of York, Woollen Cloth Manufacturer, send
greeting.
.
WHEREAS His present-most Excellent Majesty King George the Fourth,
by His Letters Patent under the Great Seal of Great Britain,,bearing date
at Westminster,, the 8th day of July, in the sixth year of His reign; did, for
Himself, His heirs and successors, give and grant unto me, the said William
Heycock, His especial licence that I, the said, William Heycock, my,exors,
admors, and, assigns, or such others as: I, the said William Heycock, 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 "CERTAIN: IMPROVEMENTS IN
THE MACHINERY FOR THE DRESSING AND FINISHING OF CLOTH;" in which said
Letters Patent is contained a proviso obliging me, the said William Heycock,
by an instrument in writing under my hand and seal, particularly to describe
and ascertain the nature of my said Invention, and in what manner the
same is to, be performed, and to cause the same to be enrolled in His
said Majesty's High Court of Chancery within six calendar months, next
and immediately after the date of the said 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
William Heycock,; do hereby declare the nature of my said Invention to
consist in pressing, damping, heating, and laying or drawing in the nap of cloths
by means of an improved machine which performs all these operations at the

page_text: same time; and, in further compliance with the said proviso, I, the said
William Heycock, do hereby describe the manner in which I perform my said
Invention by the following description thereof, reference being had to the
Drawing annexed, and the Figures marked thereon, that is to say :-
DESCRIPTION OF THE DRAWING.
Figure 1 is a section of my said improved machine, which as it shews by the
red line the passage of the cloth through it, will more readily convey an idea, of
the machine, and its general application. The parts marked A are the frame-
work, here represented as made of cast iron, and the cloth is supposed to be
moving in the direction of the arrows. B is a steam pipe communicating with
C, which is a steam case or steam box, having a number of small holes pierced
in its upper side, through which the steam escapes upwards, and is caught or
condensed upon
the under side of the roller D, the condensation being produced
merely by its passage through the intermediate atmosphere. The roller D is
covered with a spongy kind of cloth for the purpose of absorbing and becoming
saturated with the condensed steam or water, and thus damping the cloth in its
passage over it. E is a small roller, the effect of which is merely to press the
cloth on the roller below in order to damp it. G is a stone roller of 8 or 9
inches, diameter, for the purpose of grinding down, as it were, the nap or face
of the cloth, and thus rendering it soft and smooth. This roller I have hitherto
made of freestone. His an ordinary revolving brush roller, such as is used in
various machines now in use for dressing cloth; and K is a small roller,
capable of adjustment by means of its bearing sliding, up and down in the
slot J. This roller determines the degree of stress or pressure to be thrown
on the brush and stone rollers, it being evident that the lower the bearing of
the roller K is placed in the slot J-the greater. will be the stress or pressure
of the cloth upon the brush and stone rollers. L, M, are two hollow metal
cylinders, to be heated by steam by any of the ordinary methods now in use.
The cloth, will seen, passes under the lower of these two cylinders, which
is also the larger one, and over the upper one, which is the smaller. The object
of these two cylinders is to heat and and press the cloth when in a damp state.
N, P, are two drawing rollers, merely to secure the regular passage of the
cloth through the machine. Q is a pipe for conveying the steam from the
cylinders M, L.
Fig. 2 is an elevation of one side of my said machine; and here it should
be observed that similar letters refer to similar parts in all the Figures.
R, R, are two rack wheels, with a chain for giving the necessary increased
velocity to the drawing rollers.
Fig. 3 is an elevation of the other side of my said machine, and shews the

page_text: cogged wheels and pinions which give the respective proportionate velocities
to the various rollers connected with them and to the cylinders, and by which
it will be seen the velocity of the stone roller and the brush roller is much
greater that of the other rollers or of the cylinders. S is the steam pipe for
conveying steam into and thus heating the cylinders M, L.
Fig. 4 is a plan of my said Invention; and Fig. 5 is a front elevation of the
same.
Now whereas I have here described a whole or complete machine, and which
I call a finishing machine, but whereas I only claim as my Invention the
following improvements, being only parts of the said machine, that is to say:―
First, the steam case or box C, with the roller D, as the mode of damping
the cloth.
Secondly, the stone roller G.
And,
Thirdly, the two heated metal cylinders L and M.
And these said first, second, and hird improvements being, to the best of
my knowledge and belief, entirely new, and never before used within that part
of His said Majesty's United Kingdom of Great Britain and Ireland called
England, His said Dominion of Wales, or Town of Berwick-upon-Tweed, I do
hereby declare this to be my Specification of the same, and that I do verily
believe this my said Specification doth comply in all respects, fully and without
reserve or disguise, with the proviso in the said herein-before in part recited
Letters Patent contained, wherefore I hereby claim to maintain exclusive right
and privilege to my said Invention.
In witness whereof, I, the said William Heycock, have hereunto set my
hand and seal, this Twenty-sixth day of December, in the year of
our Lord One thousand eight hundred and twenty-five.
Inrolled the Fourth day of January, in the year of our Lord One
thousand eight hundred and twenty-six.
