IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1868

page_text: LETTERS PATENT to Robert Clough, of Grove Mill, Keighley, in the
County of York, Worsted Spinner and Manufacturer, for the
Invention of "IMPROVEMENTS IN LOOMS FOR WEAVING."
Sealed the 22nd December 1868, and dated the 26th June 1868.
PROVISIONAL SPECIFICATION left by the said Robert Clough at
the Office of the Commissioners of Patents, with his Petitiou, on
the 26th June 1868.
I, ROBERT CLOUGH, of Grove Mill, Keighley, in the County of York,
Worsted Spinner and Manufacturer, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN LOOMS FOR WEAVING," to be as
follows:-
This Invention relates to means of working healds or heddles of looms
employed for weaving fabrics technically known as 'lastings" and
"serge-de-berries," and the object is to enable the weights employed for
lifting the said healds or heddles to be regulated or adjusted in their
weight or pressure according to the sort or quality of cloth to be woven,
without having the said weights to change as heretofore. For this

page_text: purpose I employ a series of ordinary jack-rods and levers instead of
the bowls or pullies and cords now used to attach the top part of the
healds to, the bottoms being attached to levers operated by treading
tappets as usual; and I employ a series of levers, each being hinged
at one end to the loom end frame, and the other attached by cord or rod
to a lever fixed on one of the jack-rods. The weights are attached
to these levers and are capable of. being moved thereon as required, so as
to regulate or adjust their pressure or action on the bealds in lifting
them.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Robert Clough in the Great Seal Patent Office
on the 26th December 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT.
CLOUGH, of Grove Mill, Keighley, in the County of York, Worsted
Spinner and Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her.
Letters Patent, bearing date the Twenty-sixth day of June, in the year
of our Lord One thousand eight hundred and sixty-eight, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Robert Clough, Her special licence,
that I, the said Robert Clough, my executors, administrators, and assigns,
or such others as I, the said Robert Clough, my executors, adminis-
trators, 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," upon the condition (amongst others) that I, the said
Robert Clough, 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 Robert Clough, do hereby
declare the nature of my 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 and accompanying Sheet of Drawings (that
is to say):-
This Invention relates to means of working healds or heddles of looms
employed for weaving fabrics, technically known as "lastings" and
"serge-de-berries," and the object is to enable the weights employed for
lifting the said healds or heddles to be regulated or adjusted in their
weight or pressure according to the sort or quality of cloth to be woven,
without having the said weights to change as heretofore. For this
purpose I employ a series of ordinary jack-rods and levers (instead of
the bowls or pullies and cords now used) to attach the top parts of the
healds to, the bottoms being attached to levers operated by treading
tappets as usual; and I employ a series of levers, each being hinged
at one end to the loom end frame, and the other attached by cord or rod
to a lever fixed on one of the jack-rods. The weights are attached
to these levers and are capable of being moved thereon as required, so as
to regulate or adjust their pressure or action on the healds in lifting
them.
In order that this Invention may be clearly understood I herein give
reference to an accompanying Sheet of Drawings of an ordinary loom,
with my improvements applied thereto.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is an end elevation of such parts of the said loom as are
required to shew the application of the said Invention, and Fig. 2 is
the front elevation of same.
A are the ordinary jack-rods and their segment or arched ended levers,
which by cords B are connected to the top parts of the healds Cas
usual. The bottom parts of the said healds are connected by links D
and tee rods E to ordinary treading levers F, which are operated by
treading tappets G in the usual manner. Hare a series of levers which
are hinged at I to a frame J fixed to the loom end. Each of these
levers is connected by a rod K to a lever L on one of the jack-rods, and
on each of these levers H is a weight M, which is capable of being
moved thereon and secured by set screws N in any position, so as to
regulate or adjust the pressure on the healds required for lifting them
according to the sort or quality of cloth or fabric being woven. The
said weighted levers are guided in their motions by gratings or a frame

page_text: with slot holes P fixed to the loom end, and to prevent noise by sudden
drops or to break their fall a cushion of india-rubber or other similar
substance R is placed and secured on a bed fixed to the bottom of the
frame.
It will be observed that by this combination and arrangement of
apparatus the ordinary treading tappets and levers operate upon the
healds to draw or pull them down, and soon as the tappets cease to act
the weighted levers react to lift the said healds with such amount of
force as may be found requisite, and which can easily and readily be
regulated according to circumstances,
Having thus described the nature of my said Invention, and shewn
by Drawings how the same is to be or may be performed or carried into
practical effect, I would have it understood that I do not confine myself
to the precise details as herein set forth, nor do I claim any of the parts
separately considered, but what I do claim as of my Invention is, the
combining ordinary jack-rods and treading levers with adjustable
weighted levers for working healds, in manner substantially as herein
described and shewn in the accompanying Sheet of Drawings.
In witness whereof, I, the said Robert Clough, have hereunto set
my hand and seal, this Twenty-fourth day of December, in
the year of our Lord One thousand eight hundred and sixty-
eight
Signed, sealed, and delivered by
the within-named Robert Clough,
in the presence of
