DAZED LOONS BAD WEAVING
Year: 1860

page_text: LETTERS PATENT to James Aspell, of Middleton, in the County of Lan-
easter, Manufacturer, and Edward Booth, of Tonge, near Middleton,
Manager, and James Hurst, of the same Place, Overlooker, for the
DAZED LOONS BAD WEAVING"
Sealed the 27th March 1861, and dated the 28th September 1860.
PROVISIONAL SPECIFICATION left by the said James Aspell, Edward
Booth, and James Hurst at the Office of the Commissioners of Patents,
with their Petition, on the 28th September 1860.
We, JAMES ASPELL, of Middleton, in the County of Lancaster, Manu-
facturer, and EDWARD BOOTH, of Tonge, near Middleton, Manager, and JAMES
HURST, of the same Place, Overlooker, do hereby declare the nature of the
said Invention for "A CERTAIN IMPROVEMENT IN POWER LOOMS FOR WEAVING,"
to be as follows:-
Our Invention relates to that portion of the power loom known as the
"letting off" motion, and is similar in character to a motion for "taking up '
the cloth, for which Letters Patent have been previously granted to us bearing
date 20th March 1860, No. 723, in which a "spiral ratchet wheel" was
employed to regulate the "taking up" of the cloth, and the pawls transferred
from the smaller to the greater diameter thereof. Now, our Invention consists
in the employment and use of a "spiral ratchet wheel" for regulating the
"letting off" of the warp from the warp beam, but the action of the pawls

page_text: are reversed, that is, carried from the greater to the smaller diameter of
the spiral ratchet wheel by means of a bell crank lever, one end being attached
to a block or roller, and presses upon the periphery of the warp beam, and
following the decreasing diameter of the warp beam gives the necessary
backward motion to the carrier, so that an equal amount of yarn is "let off"
from the commencement to the completion of the piece, and the uniformity of
the same is regulated. The pawls for actuating the spiral ratchet wheel
receive motion from the swing or rocking shaft, or from any other convenient
part of the loom.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Aspell, Edward Booth, and James Hurst in the Great
Seal Patent Office on the 28th March 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JAMES
ASPELL, of Middleton, in the County of Lancaster, Manufacturer, and EDWARD
BOOTH, of Tonge, near Middleton, Manager, and JAMES HURST, of the same
Place, Overlooker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of September, in the year of our
Lord One thousand eight hundred and sixty, in the twenty-third year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said James Aspell, Edward Booth, and James Hurst, Her special license
that we, the said James Aspell, Edward Booth, and James Hurst, our
executors, administrators, and assigns, or such others as we, the said James
Aspell, Edward Booth, and James Hurst, 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 "A CERTAIN IMPROVEMENT IN LOOMS FOR WEAVING," upon the
condition, amongst others, that we, the said James Aspell, Edward Booth,
and James Hurst, by an instrument in writing under our hands and seals, or
under the hand and seal of one of us, 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.

page_text: NOW KNOW YE, that I, the said James Aspell, do hereby declare the
nature of our 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, that is to say:-
66
Our Invention relates to that portion of the power loom known as the
"letting off" motion, and is similar in character to a motion for taking up the
cloth, for which Letters Patent have been previously granted to us, bearing
date Twentieth March One thousand eight hundred and sixty, in which a
spiral ratchet wheel" was employed to regulate the "taking up" of the
cloth, and the pawls transferred from the smaller to the greater diameter
thereof. Now, our Invention consists in the employment and use of a "spiral
ratchet wheel" for "letting off" the warp from the warp beam, but the action
of the pawls are reversed, that is, carried from the greater to the lesser
diameter of the spiral ratchet wheel by means of a bell crank lever, one end
being attached to a block or roller, and presses upon the periphery of the cloth
beam, and following the decreasing diameter of the warp beam gives the
necessary backward motion to the carrier, so that an equal amount of yarn is
"let off" from the commencement to the completion of the piece, and the
uniformity of the same is regulated. The pawls for actuating the spiral ratchet
wheel receive motion from the swing or rocking shaft, or any other convenient
part of the loom.
Having now described the nature of the said Invention, together with the
manner of performing the same, we wish it to be distinctly understood that we
claim the use of the before-named spiral ratchet wheel for "letting off" the
warp from the warp beam, the construction of the spiral ratchet wheel being
similar to that described in the Specification of our before recited Letters
Patent, wherein it is employed for "taking up" the cloth; the present Inven-
tion and claim being for "letting off" the warp, as herein-before described an I
set forth.
In witness whereof, I, the said James Aspell, have hereunto set my
hand and seal, this Twenty-sixth day of March, in the year of our
Lord One thousand eight hundred and sixty-one.
JAMES ASPELL. (L.S.)
