PROVISIONAL SPECIFICATION left by the said Charles Barraclough
at the Office of the Commissioners of Patents, with his Petition,
on the 19th October 1853.
I, CHARLES BARRACLOUGH, of Halifax, in the County of York,
Mechanic, do hereby declare the nature of my Invention for "IMPROVE-
MENTS IN THE MANUFACTURE OF CARPETS AND OTHER FABRICS" to be as
follows:-
This Invention relates to looms for weaving terry or cut pile fabrics
by power by the use of wires, and it has for its object improvements in
the apparatus employed for stopping such looms should a wire not be
correctly taken or a weft not thrown in to the shed. For this purpose
the wire carrier has applied to it an instrument or catch, which, if not
supported, descends and comes in the way of a lever or instrument, and
is thus the means of stopping the loom, but if the carrier takes a
wire correctly the loom goes on working; and there are stationary rods
resting in grooves in the shuttle race near the selvages of the fabric,

page_text: and on which the weft, if there be any, rests; and there are levers,
having their axes at the back of the slay board, actuated by a cam at
either side of the loom, which, when a weft is thrown in, descends upon
it wherever the weft may be, and are prevented descending further;
but if there be no weft, the levers descend further, and thus cause the
Jeem to be stenned
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Charles Barraclough in the Great Seal Patent
Office on the 19th April 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
CHARLES BARRACLOUGH, of Halifax, in the County of York, Mechanic,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by' Her
Letters Patent, bearing date the Nineteenth day of October, in the year
of our Lord One thousand eight hundred and fifty-three, in the seven-
teenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Charles Barraclough, Her special
licence that I, the said Charles Barraclough, my executors, administra-
tors, and assigns, or such others as I, the said Charles Barraclough, 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 "IMPROVE
MENTS IN THE MANUFACTURE OF CARPETS AND OTHER FABRICS," upon the
condition (amongst others) that I, the said Charles Barraclough, by
an instrument in writing under my hand,and seal, 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 Charles Barraclough, do hereby
declare the nature of the said Invention, and in what manner the same

page_text: is to be performed, to be particularly described and ascertained in and
by the following statement thereof (that is to say):
This Invention relates to looms for weaving terry or cut pile fabrics
by power by the use of wires, and it has for its object improvements
in the apparatus employed for stopping such looms should a wire not
be correctly taken or a weft not thrown in to the shed.. For this pur-
pose
the wire carrier has applied to it an instrument or catch, which, if
not supported, descends and comes in the way of a lever or instrument,
and is thus the means of stopping the loom, but if the carrier takes
a wire correctly the loom goes on working; and there are stationary
rods resting in grooves in the shuttle race near the selvages of the
fabric; and on which the weft, if there be any, rests; and there are
levers, having their axés at the back of the sley board, actuated by a
cam at either side of the loom, which, when a weft is thrown in, descend
upon it wherever the weft may be, and are prevented descending
further; but if there be no weft, the levers descends further, and thus
cause the loom to be stopped.
And in order that my Invention may be most fully understood, and
readily carried into effect, I will proceed to describe the means pursued
by me. I would here remark that these improvements relate more
particularly to those descriptions of looms for weaving carpets and
other fabrics for which Patents have been obtained by George Collier
and others, and the Drawings show these improvements applied to a
loom of this description; and as the same has been most fully described
in former Patents it will not be necessary for me to enter into a
minute description of the working thereof, only in as far as regards my
present improvements.

DESCRIPTION OF THE DRAWINGS.
Figure 1, shows a vertical section, and Figure 2, a front view of a
loom suitably arranged for weaving carpets and other piled fabrics,
having my improvements, applied thereto; the other Drawings show
separate views of some of the parts on a larger scale, and of some of
the cams employed for giving inotion to those parts which constitute
my present improvements; and as the nature of these Drawings is

page_text: written thereon it will not be necessary to repeat the same.
.
a, a, is the
wire carrier or instrument, formed with a forked end, which rises and
receives' the end of the wire when it is drawn out of the woven fabric,
and conducts it into a position to be again inserted into the shed.
a', are studs or projections on the wire carrier, which pass through
and move freely up and down in slots formed in the bar or instrument b,
and cause it to be moved to and fro with the wire carrier. The bar b,
at its upper end is bent at right angles, as shewn, so as to rest and be
suspended on the wire, when it is lifted by the forked end of the wire
carrier to be conducted towards the shed, the bar at other times.
is a
resting on a fixed step attached to the framing of the loom.
spring catch let into the side of the bar or instrument, which comes
in contact with a projection on the lever arm c, (when the bar b, is
moved towards the shed with the wire carrier) should a wire fail to be
taken correctly by the drawing out apparatus; but when a wire is cor-
rectly taken by the rising up of the forked end of the wire carrier, then
the bar b, will be raised and suspended on the wire, and the spring
catch will pass over the projection on the lever armi c, and the wire will
be conducted into a position to be inserted into the shed, the spring
catch in its return movement passing freely over the projection on the
lever arm c. When a wire fails to be taken by the forked end of the wire
carrier a the bar 6 will not be lifted with the carrier a, and the spring
catch will come in contact with the projection on the lever arm c
fixed on the axis c', and the lever arm fixed on the axis c. will be
disengaged from the lever arm c" fixed on the axis c', on which is fixed
the throwing off lever c³, the lever arm being at all times pulled
upwards by a spring to cause the lever arm c. to throw out the spring
rod from its slot, by which the loom will be stopped, as is well under-
stood. The to and fro and up and down movements are given to the
wire carrier a, in like manner to that described in the former Patents
before referred to.
I will now describe my improvements for stopping the loom when
there is no weft. d, d, are levers (one on each side of the loom)
moving on axes at the back of the sley board; these levers are
formed at the front end into a fork or grid, as shewn separately at

page_text: Figure 3, and they move up and down in spaces formed by stationary
rods let into or across the shuttle race near the selvages of the fabric,
and are supported by fixed brackets e, e, as shown. The levers d, d,
receive motion in the following manner :-f, f', are cams on the cam shaft
which give motion to the levers g, g', moving on the axis g²; the levers
9, g', are connected by chains or otherwise to the levers h, h', fixed on
the axes i, i, upon which are fixed the lever arms j, j', which are con-
nected by links h, k, to the levers d, d, so as to cause them to rise and
fall when acted upon by their respective cams. The links k, k¹, carry
projecting arms, which act upon the lever arms 1, 1, fixed on the
axis c'. When either of the levers d, d, descend between the spaces
formed by the stationary rods (should the weft fail to be laid across the
spaces so as to support its lever d), and when either of the arms k¹
descend and depress one of the levers l, motion will be communicated
to the axis c', the lever arms c, e, will be disengaged, and the loom
will be stopped, as before described.
Having thus described the nature of my Invention, and the manner
of performing the same, I would have it understood that I do not con-
fine myself to the precise details herein shewn and described so long as
the peculiar character of my Invention be retained; but what I claim
is, the combined apparatus herein described for stopping a loom should
a wire not be correctly taken, or if a weft not thrown.
In witness whereof, I, the said Charles Barraclough, have here-
unto set my hand and seal, this Twenty-seventh day of March,
in the year of our Lord One thousand eight hundred and
fifty-four.
Witness,
THOS PALETHORPE,
CHARLES BARRACLOUGH. (L.S.)
Halifax.
