IMPROVEMENTS IN LOOMS FOR WEAVING BRUSSELS CARPETS AND OTHER TERRY FABRICS
Year: 1857

page_text: LETTERS PATENT to Brook Hodgson and John Carter, of Halifax, in the
County of York, for the Invention of "IMPROVEMENTS IN LOOMS FOR
WEAVING BRUSSELS CARPETS AND OTHER TERRY FABRICS."
Sealed the 14th August 1857, and dated the 26th February 1857.
PROVISIONAL SPECIFICATION left by the said Brook Hodgson and John
Carter at the Office of the Commissioners of Patents, with their Petition,
on the 26th February 1857..
We, BROOK HODGSON and JOHN CARTER, of Halifax, in the County of York,
do hereby declare the nature of the Invention for "IMPROVEMENTS IN LOOMS
FOR WEAVING BRUSSELS CARPETS AND OTHER TERRY FABRICS," to be as follows:-
This Invention has for its object improvements in looms for weaving
Brussels carpets and other terry fabrics. For these purposes, in order to
introduce and withdraw the wires employed when weaving terry fabrics, a
double volute apparatus is applied to a loom. The volute acts on a suitable
slide, and moves it to and fro, by which means motion is given to a carriage or
apparatus arranged to take hold of a wire, then to move out with it from the
selvage of the cloth, then to carry it back towards the reed of the loom, then
to move the wire into the open shed, then to leave hold of the wire, and to go
forward to take hold of and in like manner to draw out another wire. The
volute acts on friction rollers carried by axes fixed to the slide. The volute
receives motion from the main shaft of the loom.

by the said Brook Hodgson and John Carter in the Great Seal Patent
Office on the 26th August 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME; we, BROOK
HODGSON and JOHN CARTER, of Halifax, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of February, in the year of our
Lord One thousand eight hundred and fifty-seven, in the twentieth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said Brook Hodgson and John Carter, Her special licence that we, the
said Brook Hodgson and John Carter, our executors, administrators, and
assigns, or such others as we, the said Brook Hodgson and John Carter, our
executors, administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands, and Isle
of Man, an Invention for "IMPROVEMENTS IN LOOMS FOR WEAVING BRUSSELS
CARPETS AND OTHER TERRY FABRICS," upon the condition, amongst others, that
we, the said Brook Hodgson and John Carter, our executors or adminis-
trators, by an instrument in writing under our or their hands and scals, or..
under the hand and seal of one of us or them, should particularly describe and
ascertain the nature of the said Invention, and in what manner the same was
to be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that we, the said Brook Hodgson and John Carter, do:
hereby declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and
by the following statement thereof, that is to say:-
This Invention has for its object improvements in looms for weaving
Brussels carpets and other terry fabrics. For these purposes, in order to
introduce and withdraw the wires employed when weaving terry fabrics, a
double volute apparatus is applied to a loom. The volute acts on a suitable:
slide, and moves it to and fro, by which means motion is given to a carriage
or apparatus arranged to take hold of a wire, then to move out with it from
the selvage of the cloth, then to carry it back towards the reed of the loom,
then to move the wire into the open shed, then to leave hold of the wire and
to go forward to take hold of and in like manner to draw out another wire.

page_text: The volute acts on triction rollers carried by axes nixed to the side. The
volute receives motion from the main shaft of the loom.
Ilaving thus stated the nature of our said Invention, we will proceed more
fully to describe the manner of performing the same.
DESCRIPTION OF THE DRAWING.
Figure 1 represents part of an end view of a loom; Figure 2 represents
the double volute and slide; Figure 3 represents the apparatus for holding
the wire; Figure 4 represents the slide, shewing the friction rollers. Figure 3
is a full size view; Figures 1, 2, and 4 are made upon a scale of about
3 inches to the foot. In Figuro 1, a, a, represents part of the framing of the:
loom;
b is the volute; c is a segmental rack or quadrant, which gives motion
to the pinion d on the volute shaft e, which actuates the volute, the quadrant c
receiving its motion from the tappet shaft 2 in Figure 2; f represents the
slide, which is actuated by the volute; be is a front view of the volute,
shewing its action upon the friction rollers on the slide, which gives the
requisite to-and-fromotion for inserting and withdrawing the wires, and we-
wish it to be understood that one side of the wing inserts and the other
withdraws the wire. This peculiar piece of mechanism is obliged to be set
at a certain angle, so as to allow only one friction roller to be acted upon at
once, but at the same time it must be understood that before the one friction
roller departs from the volute another has just entered, and in consequence
keeps up a continuous motion. 9 represents a projecting arm from the slide
bar, with which is connected the wire holder in its position for inserting the
wire. In Figure 1, h is a lever, to which is attached a rod j for the purposo
of taking the wire opposite the open shed after its withdrawal from the fabric
ready for insertion. The lever his actuated by the cam i; the rod j is used
for a double purpose.
Having now described one, we will proceed to describe the other.
Immediately after the insertion of the wire the cam i causes the rod j to
move the wire holder over to the wire nearest the breast beam or piece roller
ready for withdrawing another wire; when the wire is withdrawn from the
fabric, the wire holder is brought over a sufficient distance so as to cause it
to present the wire end in the proper position for insertion; this is per-
formed by the action of a cam on the tappet shaft 7 in connection with a lever
and a hook rod. is a lever, which is actuated by the cam l. To the lover k
is connected a rod m, which releases the wire holder after insertion, and holds
it sufficiently high to clear the wire heads that are in the fabric as the rod j
pushes it over to take hold of another wire. Figure 3 is the wire holder

page_text: n is an india-rubber spring in connection with the sliding part of the wiro
holder, the effect of which always keeps the slide o pressed on the wire head
during its withdrawal and insertion; m³ is the rod end (see Figure 1) for
releasing the wire holder, after insertion; p is the wire head or wire ready
for insertion or withdrawal.
Having now described the nature of our Invention, we wish it to be under-
stood that we do not claim any of the parts separately, nor do we confine
ourselves to the particular details herein described, as various modifications
might be introduced without interfering with the general principle of our
Invention; but what we claim in these improvements is, the combined
apparatus herein described.
In witness whereof, we, the said Brook Hodgson and John Carter, have
hereunto set our hands and seals, this Twenty-first day of August, in
the year of our Lord One thousand eight hundred and fifty-seven.
