IMPROVEMENTS IN LOOMS
Year: 1874

page_text: LETTERS PATENT to Richard Gill, of Bradford, in the County
York, Designer, for the Invention of "IMPROVEMENTS IN LOOMS,"
COMPLETE SPECIFICATION filed by Richard Gill at the Office of
the Commissioners of Patents, with his Petition and Declaration,
on the 16th October 1874, pursuant to the 9th Section of the Patent
Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
GILL, of Bradford, in the County of York, Designer, send greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS
IN Looms," and have petitioned Her Majesty to grant unto me, my
executors, administrators, and assigns, Her Royal Letters Patent for
the same, and have made solemn Declaration that I am the first and
true Inventor of the same.
NOW KNOW YE, that I, the said Richard Gill, do hereby declare
that the following Complete Specification, under my hand and seal,

page_text: This Invention relates to certain improvements in the method of and
apparatus for wrapping the piece, during the process of weaving, round
the breast beam of an ordinary loom by means of one beam only, by
which means I gain a more uniform tention throughout the entire
length of the piece than by the use of two beams with levers and
weights as hitherto in common use.
By my improved method I can weave any number of picks to the
inch without the aid of change wheels hitherto in common use.
I accomplish it in the following manner :-Instead of the catch wheel
which is used in ordinary looms, for giving motion to the breast beam
for drawing off the piece I place a friction wheel, the periphery of
which may be concave, convex, grooved, or turned flat, to various
sections, which wheel I cause to be sccured to one end of a shaft, in
lieu of catch wheel, supported by a bracket fixed to framework of loom.
On the other end is fixed a toothed wheel gearing into another toothed
wheel fixed to the end of breast beam shaft, to which motion is imparted
in the following manner :-To one or both of the bars or swords sup-
porting the sleyboard I fix a bracket, which is connected by means of a
rod working on studs to a lever having the friction wheel shaft as a
centre. The said lever is extended beyond the shaft at a suitable angle,
to the end of which is fitted a dog fitting the groove in the friction
wheel. When the loom is put in motion the bars supporting the sley-
board gives a reciprocating motion to lever; when moving one way the
dog grip revolves the friction wheel and toothed wheels gearing to breast
beam. Another dog is placed to prevent the the slackening of the tention
of the piece, during the return stroke of the lever the piece is drawn
off under the ordinary top roller over the breast beam or beam that the
piece is wrapped round. To the end of the said roller I fix a strap with
rod coupling to a lever working on a stud fixed in loom end or any
other convenient place; the other end of the 'said lever is coupled to the
long end of dog lever, in which is cut a slot; as the piece wraps round
the breast beam it gets larger in diameter and lifts up roller with strap

its entire length.
In witness whereof, I, the said Richard Gill, have hereunto set
my hand and seal, this Twelfth day of October, in the year of
Lord One thousand eight hundred and seventy-four.
Signed, sealed, and delivered by
the said Richard Gill, in the
presence of
JOHN WAUGH,
RICHARD GILL. (L.S.)
Engineer,
Bradford.
