County of Middlesex, Engineer & Patent Agent, for the Invention
of "IMPROVEMENTS IN LOOMS FOR WEAVING STAYS, OR CORSETS & OTHER.
SIMILAR ARTICLES."-A communication from.. abroad by Alexis Manigot,
of Paris, in the Empire of France, Merchant.
Sealed the 22th August 1861, and dated the 23rd April 1861.
PROVISIONAL SPECIFICATION left by the said William Clark, at the
Office of the Commissioners of Patents, with his Petition, on the 23rd
April 1861.
I, WILLIAM CLARK, of 53, Chancery Lane, in the County of Middlesex,
Engineer & Patent Agent, do hereby declare the nature of the said. Inven-.
tion for "IMPROVEMENTS IN LOOMS FOR WEAVING STAYS OR CORSETS & OTHER
SIMILAR ARTICLES," to be as follows:-
This Invention relates to the application of multiple rollers: to loomis
employed in weaving corsets and other similar articles...
This improved arrangement of of loom will be fully understood by referring
to the annexed Drawings, Fig. 1 of which represents a lateral vertical section
of this improved system as applied to looms. Fig. 2 shows a front elevation
of the same; Fig. 3 is a plan of the batten furnished with the shuttle boxes
and their accessories. This multiple roller may be applied to any kind of
loom, with the batten having its fixed point of oscillation either at the bottom
or top of the frame.
I fit between the supports a of the loom a cast-iron frame,b secured at
the base and furnished with cross bars c, the head of frame beconsists of two

page_text: bearings & carrying the shaft e, on this shaft are mounted the grooved rollers
f, the number of which can be varied at will and form by their assemblage
the multiple roller which forms the principal feature of this Invention; above
the multiple roller f, f, f, f, is disposed another roller, composed as the other,
of a series of grooved rollers 9, 9, 9, 9, all in connection with each other on an
axis which turns in bearings i, the distance between the multiple rollers f & g
is regulated by means of a screw j, between which rollers the fabric passes
as it is woven. The shaft e of the multiple roller f. f, independently of its
bearings d is further adjustable in the bearings k, bolted to the uprights a
of the loom. Motion is given to each of the rollersf composing the multiple
roller in the following manner-An intermediate pinion 7, mounted freely
on the shaft m, gears with the roller f, which is itself geared with a pinion n,
which is of a thickness to allow of another pinion o being interposed between
two pinions on the same axis, solid with the one n, but of a rather less
diameter. A small pinion p, which gears with o, is solid, with a ratchet
wheel mounted on the same shaft. This wheel q is actuated by the catch r
which is itself set in motion by the levers which work the jacquard. It
will thus be seen that by this combination, which is the same for each of
the rollers, the loom and the jacquard apparatus being suitably regulated
that the fabric may be delivered according as it is required by any particular
roller without inconvenience and with great facility of movement.
Another part of this Invention relates to the shuttle box which is arranged
in the following manner:-In the boxt (Fig. 3) are disposed two rods u, u¹,
on these rods slide the shuttle driver v, but in order to prevent the thread
from unwinding too much, when weaving at the sides of the fabric, a small
stop is employed which is raised by the jacquard at the desired moment to
prevent the shuttle y running to the end of the box t in groove x. The
shuttle employed is by preference the unwinding shuttle. Such is the
improvement resulting from the application of this system of multiple rollers
to looms for weaving corsets & other articles.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Clark in the Great Seal Patent Office on the
21st October 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
CLARK, of 53, Chancery Lane, in the County of Middlesex, Engineer & 3
Patent Agent, send greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-third day of April, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fourth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said William Clark, Her special licence that I, the said William
Clark, my executors, administrators, and assigns, or such others as I, the
said William Clark, my 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 STAYS OR CORSETS AND OTHER SIMILAR
ARTICLES," a communication to me from abroad by Alexis Manigot, of
Paris, in the Empire of France, Merchant, upon the condition (amongst
others) that I, the said William Clark, my executors or administrators, by
an instrument in writing under my, or their, or one of their hands and seals,
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 I, the said William Clark, 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, reference being. had to the Sheet of Drawings hereunto annexed,
and to the letters and figures marked thereon (that is to say):-
This Invention relates to the application of a multiple roller to jacquard
looms for the purpose (when weaving stay gussets or other anologous
articles) of bringing back the weft of the fabric parallel to the batten of
the loom. At present when manufacturing said stay gussets, it is necessary
in the weaving to suppress a certain portion of the weft threads which causes
considerable loss of time to the attandant in drawing out the fabric, which
he fixes by means of a pointer bar and brings back the line of the weft
parallel to the batten of the loom before he can proceed with the weaving.
All this may be avoided by the employment of the multiple roller according
to this Invention applied to jacquard rollers, the tension being exerted
mechanically on those parts of the fabric requiring it while the attendant
proceeds with the weaving without interruption.
The annexed Drawing represents the multiple rollers according to this
Invention Fig. 1 being a longitudinal vertical section of the rollers applied
i

page_text: to a self-acting loom; Fig. 2 a front view of same; Fig. 3 a plan of the
batten furnished with a shuttle box and its accessories; Fig. 4 shows an end
view of a second arrangement of multiple rollers; Fig. 5 a longitudinal
section of the same; Fig. 6 an end. view of said multiple rollers, while
Fig. 7 shows a specimen of the woven fabric obtained. In all the Figures
the same letters of reference indicate like parts where they recur.
a, uprights of a loom which may be of any kind, the batten having its
point of oscillation either fixed at bottom or at the upper part of the
frame; b, frame of cast iron, adapted to its position between the uprights a
of the loom, fixed to the ground and furnished with stays c; d, brackets
fixed to frame b, having bearings supporting shaft e; f, grooved rollers keyed
on shaft c, they may be covered with cloth or other material, their number
being varied as required for forming by their combination the multiple
rollers of this Invention; g, series of grooved rollers of a similar number to
the preceding rollers f, and placed above them, they are united on an axis h
turning in brackets i, and may also be covered with cloth or other material;
j, binding screw for regulating the distance between the rollers & 9. between
which the finished fabric is held; k, brackets carrying shaft e of the multiple
roller f, bolted to the uprights a of a loom; 1, intermediate pinion mounted
on shaft m, turning freely thereon, and gearing with roller f; n, pinion actuating
said pinion 1, but of less breadth, so as to interpose between them, & on
the same shaft another pinion o solid with the one n, but of smaller diameter;
p, pinion, gearing in the one o, solid with a ratchet wheel q, and mounted on
the same shaft, this wheel q is actuated by catch r set in motion by levers s
for regulating the jacquard apparatus; t, shuttle box, in which are disposed
two rods, u, u; v, shuttle driver,. sliding on said rods u, u¹. For the
purpose of preventing the thread from unwinding to too great an extent
at the time when the work is being carried on at one side of the loom only,
a small block or stop piece is employed, this is raised through. a.groove x
by the jacquard apparatus at the desired moment to prevent the shuttle y
passing to the end of the box t. Ishaft with a perfectly turned surface
on which are keyed at each end a portion of roller 2, and a toothed wheel 3 on
shaft 1 are also loosely mounted a number of hollow shafts, one within the
other, having at each end portions of rollers 4, 5, 6, 7, & 8, the combination
of which forms the multiple roller of this Invention; these portions of multiple
rollers are geared with as many toothed wheels 9, 10, 11, 12, & 13, each
being keyed on the shaft corresponding to the portion of roller it actuates;
14, pullies gearing with toothed wheels 8, 9, 10, 11, 12, & 13, and com-
municating rotary motion thereto. It will thus be easily understood that

page_text: by these combinations, which are the same for each of the rollers, and by
suitably regulating the loom and jacquard apparatus, that the fabric may
be drawn by all or any of such rollers in particular without any difficulty and
with great smoothness of motion.
Having described the nature of the Invention and the manner of per-
forming the same, I declare that what I claim as the Invention to be
protected by the herein-before in part recited Letters Patent, is,-
First, the grooved multiple rollers either covered with cloth or uncovered,
represented at Figs. 1 & 2 of the Drawings annexed, together with the
several parts constituting the means of actuating said rollers either separately
or in combination.
Secondly, I claim the second arrangement of multiple rollers represented
at Figs 4, 5, & 6 of the Drawings, in which the different rollers are keyed
on hollow shafts receiving rotary motion from toothed wheels keyed on each
of said shafts.
Thirdly, I claim the improved arrangement of shuttle box having a rod
& also the shuttle driver and stopping block for preventing too great an
unwinding of the thread.
In witness whereof, I, the said William Clark, have hereunto set my
hand and seal, this Eighteenth day of October, in the year of our
Lord One thousand eight hundred and sixty-one.
Witness,
W. G. E. SwINNOCK,
