page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JEAN
THOMAS LAURENTE LAMY GODARD, of Christopher Street, Finsbury Square, in
the City of London, Merchant, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Seventh day of November, in the third year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto me, the said
Jean Thomas Laurente Lamy Godard, Her especial licence, full power, sole
privilege and authority, that I, the said Jean Thomas Laurente Lamy Godard,
my exors, admors, and assigns, or such others as I, the said Jean Thomas
Laurente Lamy Godard, my exors, adñiors, 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, the
Invention of "IMPROVEMENTS IN LOOMS FOR WEAVING TO BE WORKED BY STEAM
OR OTHER POWER," communicated to me by a certain foreigner residing abroad;
in which said Letters Patent is contained a proviso that I, the said Jean
Thomas Laurente Lamy Godard, shall cause a particular description of the
nature of the said Invention, and in what manner the same is to be performed,
to be inrolled in Her said Majesty's High Court of Chancery with 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.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the
said Jean Thomas Laurente Lamy Godard, do hereby declare the nature of
the 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 had to the Drawing hereunto annexed, and to the figures and
letters marked thereon, that is to say:-
The Invention relates to a peculiar mode of apparatus applied to looms in
order to size or starch the warp in the process of weaving, in places of
starching or sizing the warp by hand as now practised. And further, the
Invention also relates to a mode of winding up the woven fabric as it is
made.
And in order to give the best information in my power, I will proceed to
describe the Drawing hereunto annexed.
DESCRIPTION OF THE DRAWING.
Fig. 1 represents a side view of a loom having the improved apparatus
applied thereto. It will not be necessary to describe the various parts of the
loom, which are well known and in general use, but simply confine the
description to the improved apparatus applied thereto, and it may at once be
stated that the construction of the loom may be varied, or, in other words, the
improved construction of apparatus may be applied to any of the various con-
structions of looms wherein it is desired to apply starch, or size, or other usual.
fluid to the warp. a is the warp beam, and the cloth roller or beam; the warp is
indicated by red lines, and it will be seen to pass over a roller c which revolves
in the trough d, and it is important to remark that the roller c is covered with
woollen cloth and revolves in the trough d, and thereby becomes saturated on
the surface with starch or other usual liquid which is contained in the trough
d; and in order to regulate the quantity of starch which is delivered to the
warp, and to ensure its being equal, the surface or side of the trough over
which the warp first passes is lined or covered with woollen cloth, and the
bearings of the axes of the roller c are capable of adjustment nearer to
and further from the side of the trough, and by the coming together of the
woollen cloth with which the roller is covered, and with which the inner sur-
face of the side of the trough is lined, the starch or other liquid will be laid
smooth and equal, and the quantity delivered to the yarn of the warp adjusted
to the greatest nicety; and when the warp has received its starch or fluid it is
next operated on by a revolving brush, which is so regulated as to turn in the
same direction as the warp. travels, and the brush is composed of four surfaces
of hair each at right angles to the axis, as will readily be seen at Fig. 2,

page_text: where the brush is shown separately, and it is important that the yarn when
starched should be dried to a considerable extent before being woven into a
fabric, and for this purpose a fan or such like apparatus is applied at e; it con-
sists of a flat surface of thin wood or other material, which is affixed by two
arms to two wire rods f, which are affixed to the front framing of the loom, and
the back ends of such wire rods are attached by cords to arms g affixed to the
axis h, and consequently when that axis is moved the rods f will be moved,
and the elasticity of the rods moves them downwards; thus it will be seen
that the fan will have a quick to-and-fro movement, by which air will be
forced against the yarns of the warp; on the axis h are affixed two levers i, one
at each end, to the lower ends of which are attached a hook or driver j which
lay hold of the studs on the end of the axis of the brush, and cause it to
revolve, and motion is communicated to the axis h by the working of the
swords of the loom, there being an axis or rod which runs from sword to
sword, and is capable of movement in bearings affixed to the backs of the
swords, as is shewn in the Drawing; about the middle of the axis k is affixed
an arm 1, which is connected by a pin joint to the arm m, which arm m is
connected to the axis h, and by this means motion is given to the whole of the
machinery or apparatus, the peculiar construction of which constitutes the
Invention secured by the present Letters Patent; m' are two rods of wood
joined together at their ends, and are placed between the warp threads to keep
them separate, similar to the shed which is opened by the working of the
loom, and there are weights to keep the rods from ascending with the warp,
and there are three rods at which keep the warp correct; but in case of their
being separate and requiring to be put back from time to time according to
this arrangement, the three rods at nare attached together at their ends, and
they have cords o, by which they are prevented going forward with the warp
threads, the warp threads as they are made into cloth or fabric being drawn
between the three rods n. The mode of winding on the fabric consists of applying
the lever p and p¹ which are operated on by the treadle q.
The lever p moves
on an axis at 7, and it is so arranged that the axis may be moved from point
to point, in order that as the work or cloth roller becomes full its axis may
caused to turn a less and less distance, and thus compensate for the encreasing
diameter of the cloth on the roller. The lever p is connected by a cord to the
treadle q, and the lever at its other end is connected to the lever p¹ by a
cord; such lever p¹ moves on an axis at s, and at the front end of the lever is
attached a driver, which taking into the teeth of a ratchet wheel drives it
round, and thence by means of a train of wheels continued motion is commu-
nicated to the cloth roller.

page_text: I would remark that I am aware that it has before been proposed to employ
two rollers, one revolving in a trough containing fluid for dressing warp in
looms, and a brush moving in an opposed way to the yarn, and also a fan to
dry the warp so prepared; I do not therefore claim the application of rollers,
brushes, and fans generally for such purposes, but what I claim is,-
First, the mode of applying a covered roller and lined trough, together with
a brush working in the direction of the movement of the warp, and a fan
worked as above described, and also the mode of applying the bars m³, n, as
described.
And, secondly, I claim the mode of winding on the cloth or fabric as it is
made, as above described.
In witness whereof, I, the said Jean Thomas Laurente Lamy Godard,
have bereunto set my hand and seal, this Sixth day of May, in the
year of our Lord One thousand eight hundred and forty.
