CERTAIN IMPROVEMENTS IN LOOKS FOR WEAVING
Year: 1862

page_text: LETTERS PATENT to Joseph Place, of Over Darwen, in the County of
Lancaster, Spinner and Manufacturer, for the Invention of "CERTAIN
IMPROVEMENTS IN LOOKS FOR WEAVING."
Sealed the 28th January 1868, and dated the 4th November 1862.
PROVISIONAL SPECIFICATION left by the said Joseph Place at the
Office of the Commissioners of Patents, with his Petition, on the
4th November 1862.
I, JOSEPH PLACE, of Over Darwen, in the County of Lancaster; Spinner
and Manufacturer, do hereby declare the nature of the said Invention for
"CERTAIN IMPROVEMENTS IN LOOMS FOR WEAVING," to be as follows:-
My Invention relates to that part of the power loom known as the "treading
motion," by which the rise and fall of the healds is effected."
The improvement consists in the novel employment and use of a double set.
of "treddles," that is, one set hinged to the back rail of the loom, and projecting
forwards, and the other set of a corresponding numbér hinged to the front
rail, their ends projecting towards the others, so that such extremities may be
coupled together by a link near the middle of the depth of the loom. The
"treddles" so constructed are to be actuated by "tappets "of a suitable and
peculiar form and of less dimensions than those hitherto similarly employed,
and so calculated as to render the "shedding "motion more positive. By
this combination of small tappets and double-" treddles" looms may be driven
at a higher speed, and a considérable improvement effected in the fabric.

by the said Joseph Place in the Great Scal Patent Office on the 1st
May 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
PLACE, of Over Darwen, in the County of Lancaster, Spinner and Manufac-
turer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourth day of November, in the year of our
Lord One thousand eight hundred and sixty-two, in the twenty-sixth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Joseph Place, Her special license that I, the said Joseph Place,
my executors, administrators, and assigns, or such others as I, the said Joseph
Place, 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 "CERTAIN IMPROVEMENTS IN
LOOMS FOR WEAVING," upon the condition (amongst others) that I, the said
Joseph Place, 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 Joseph Place, 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 ascertained in and by the following
statement and accompanying Drawings (that is to say) :—
My Invention relates to that part of the power loom known as the
"treading motion," by which the rise and fall of the healds is effected.
The improvements consist in the novel employment and use of a double
set of "treddles," that is, one set hinged to the back rail of the loom, and
projecting forwards, and the other set of a corresponding number hinged to
the front rail, their ends projecting towards the others, so that such extremities
may be coupled together by a link near the middle of the depth of the loom.
The treddles so constructed are to be actuated by "tappets" of a suitable and
peculiar form and of less dimensions than those hitherto similarly employed,
and so calculated as to render the "shedding" motion more positive. By

page_text: this combination of small tappets and double "treddles" looms may be
driven at a higher speed, and a considerable improvement effected in the
fabric.
In order that the Invention may be better understood and explained in
detail, I have hereunto attached a Sheet of Drawings made upon a scale of
about two inches to the foot, similar letters of reference being marked upon
corresponding parts of the apparatus.
Fig. 1 is a sectional view taken from front to back, shewing particularly
that part of the loom, to which my improvements are applied; Fig. 2 is a
cross sectional view taken from side to side of the loom.
In Figs. 1 and 2, a, a, is the framing of the loom; 6, the yarn beam; c, c,
the healds; d, the breast beam; and e, the cloth roller, all of which are now
well known. The healds c are attached to the treddles f. f, which are hinged
to the framing at the front of the loom, and are coupled at their opposite ends
at a point about half-way between the front and the back of the loom by a
pin and slot or link to the treddles ff, the opposite ends of which are
hinged to the framing at the back of the loom in a line about opposite to the
treddles ff, the treddles f,f, being furnished with bowls, which are acted
upon by the tappets 9, 9, which are employed to actuate the healds, and are
smaller than the ordinary "tappets," which in combination with the double
treddles enables the speed of the loom to be increased.
Having now described the nature of the said Invention, together with
the method of carrying the same into practical effect, I wish it to be
distinctly understood that I claim the novel employment and use of a double
set of treddles connected together to actuate each heald, and used in com-
bination with the smaller tappets, as herein-before described, set forth, and
fully illustrated in the Drawings attached.
In witness whereof, I, the said Joseph Place, have hereunto set my
hand and seal, this Twenty-eighth day of April, in the year of our
Lord One thousand eight hundred and sixty-three.
JOSEPH PLACE. (L.S.)
