IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1866

page_text: LETTERS PATENT to David Lord; Thomas Lancaster, and Robinson
Bennett, all of Great Horton, near Bradford, in the County of York,
for the Invention of "IMPROVEMENTS IN LOOMS FOR WEAVING."
Sealed the 11th May 1866, and dated the 24th January 1866.
PROVISIONAL SPECIFICATION left by the said David Lord, Thomas
Lancaster, and Robinson Bennett, at the Office of the Commissioners
of Patents, with their Petition, on the 24th January 1866.
We, DAVID LORD, THOMAS LANCASTER, and ROBINSON BENNETT, all of
Great Horton, near Bradford, in the County of York, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN LOOMS FOR WEAVING," to
be as follows:-
The object of our Invention is to prevent the breakage of the warp and
also of the yarn in weaving. For this purpose, in place of what is known
as the "stop rod" in ordinary looms, we affix to the crank lever of the loom
an arm having a point or toe, which at stated periods during the motion of
what is known as the "working part" of the loom acts upon an arm secured
to a shaft placed under the said "working part." Upon this shaft is also
keyed a flat table, which bears an arm made or cast at right angles to and

page_text: forming part of a lever placed on the front side of the "working part."
This lever works upon a centre pin secured to the front part of the "work-
ing part," and has at the part extreme from the centre a "circular flat,"
the purpose of which will hereafter be explained, as well as a spring
pressing upon the top of the lever to keep it in proper position. A stud
is also provided (in connection with the usual break gear) of a suitable size
to receive a hole made opposite to it in the "working part" before
mentioned.
The operation is as follows:--The loom being put in motion the toe of
the arm affixed to the crank lever raises the "circular flat" in front of the
"working part" by means of the flat table; and allows the hole in the said
"working part" to cover the stud in its usual traverse; but should the
shuttle not be in its proper position the "circular flat" at once drops and
prevents the hole in the working part from covering the stud by being
opposite the aperture, the spring ordinarily used in the shuttle box and in
connection with our apparatus indicating to the arm of the crank shaft
through the intermediate lever that the shuttle is not in the right place,
and thus breakage of warp or weft is prevented, the "break gear" being
brought into operation.
..
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said David Lord, Thomas Lancaster, and Robinson Bennett
in the Great Seal Patent Office on the 24th July 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, DAVID
LORD, THOMAS LANCASTER, and ROBINSON BENNETT, all of Great Horton,
near Bradford, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of January, in the year of our

unto us, the said David Lord, Thomas Lancaster, and Robinson Bennett,
Her special licence that we, the said David Lord, Thomas Lancaster, and

as we, the said David Lord, Thomas Lancaster, and Robinson Bennett,
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," upon the condition (amongst others) that we, the said David
Lord, Thomas Lancaster, and Robinson Bennett, our executors or admi-
nistrators, by an instrument in writing under our or their hands and
seals, 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 I, the said David Lord; on behalf of myself and
the said Thomas' Lancaster and Robinson Bennett, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and':
and ascertained in and by the following
statement thereof, that is to say
9.
The object of our Invention is to prevent the breakage of the warp and
also of the yarn in' weaving. For this purpose, in place of what is known
as' the "stop rod" in ordinary looms, we affix to the crank lever of the loom
an arm having a point or toe, which at stated periods during the motion of
what is known as the "working part" of the loom acts
acts upon an arm secured
to a shaft placed under the said "working part. Upon this shaft is also
keyed a flat table, which bears or supports an arm made or cast at right
angles to and forming part of a lever placed on the front side of the
working part." This lever works upon a centre pin secured to the front
part of the "working part," and has at the part extreme from the centre a
circular flat," the purpose of which will hereafter be explained, as well
as a spring pressing upon the top of the lever to keep it in proper position.
A stud is also provided (in connection with the usual break gear) o
of a
suitable' size to receive a hole made opposite to it in the "working part"
before mentioned.

The operation is as follows: The loom being put in motion the toe of
the arm'affixed to the crank lever raises the circular flat in front of the
"working part" by means of the flat table and intermediate lever, and allows
the hole in the said "working part" to cover the stud in its usual traverse;
but should'the shuttle not be in its proper position the "circular flat" at
once drops and prevents the hole in the "working part" from covering the

by the attendant.
In witness whereof, I, the said David Lord, have hereunto set my
hand and seal, this Nineteenth day of July, in the year of our
Lord One thousand eight hundred and sixty-six.
