IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1869

page_text: LETTERS PATENT to John Wilkinson, of Bradford, in the County of
York, Overlooker, and William Scott, of Bradford, aforesaid,
Mechanic, for the Invention of " IMPROVEMENTS IN LOOMS FOR WEAVING."
PROVISIONAL SPECIFICATION left by the said John Wilkinson and
William Scott at the Office of the Commissioners of Patents, with
their Petition, on the 9th February 1869.
We, JOHN WILKINSON, of Bradford, in the County of York, Over-
looker, and WILLIAM SCOTT, of Bradford, aforesaid, Mechanic, 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 letting off the warp from the beam
and adjusting the tension thereof by the attendant at any time while
weaving; and the improvements consist in the application of a toothed
wheel to the beam to gear into another toothed wheel of smaller
diameter mounted on a stud fixed to the loom frame, and to which stud
wheel is fixed a brake pulley for a cord or belt to pass around, and then

page_text: be attached to a weighted lever; also in the application of a pair of
hand levers hinged to the loom frame, and with the handles projecting
towards the front of the loom. These levers are provided with catches
taking into a ratchet wheel fixed on the beam, and one of them is also
connected by a rod to the weighted lever, so that the attendant by
operating them may lift the weight, and thereby remove the pressure
from the brake pulley, and either let slack the warp or by means
of the catches set up the beam so as to increase the tension on the
warp.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Wilkinson and William Scott in the Great
Seal Patent Office on the 9th August 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
WILKINSON, of Bradford, in the County of York, Overlooker, and
WILLIAM SCOTT, of Bradford aforesaid, Mechanic, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Ninth day of February, in the
year of our Lord One thousand eight hundred and sixty-nine, in
the thirty-second year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto us, the said John Wilkinson and William
Scott, Her special licence that we, the said John Wilkinson and William
Scott, our executors, administrators, and assigns, or such others as we, the
said John Wilkinson and William Scott, 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
John Wilkinson and William Scott, our executors or administrators,
by an instrument in writing under our, 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 Scal Patent

page_text: catch K is hinged to the lever and rests on a projection L, which
prevents it from taking into the teeth of the wheel A when the pressure
is on the beam, but when the lever is lifted it takes into the said wheel,
and the attendant is thereby enabled to turn the warp beam backward,
and thus put any amount of tension on the warp that may be required
without having to leave the front of the loom.
Having thus set forth the nature of our said Invention, and shewn by
Drawings and description thereof how the same is or may be performed
or put into practical operation, we would have it understood that we
do not confine ourselves to the precise details herein shewn and described
as we may vary the relative sizes of the gear wheels or the size and
position of the brake pulley, or the position of the weighted lever, or we
may apply another lever or levers to act in connection or conjunction
with the said lever so as to facilitate the action on the warp beam by
the attendant; but we claim, the application of the combined means in
manner and for purposes substantially as herein described and shewn in
the accompanying Drawings.
In witness whereof, we, the said John Wilkinson and William
Scott, have hereunto set our hands and seals, this Seventh day
of August, in the year of our Lord One thousand eight hundred
and sixty-nine.
JOHN WILKINSON. (L.s.)
WILLIAM SCOTT. (L.S.)
