IMPROVEMENTS IN POWER-LOOMS.
Year: 1856

page_text: LETTERS PATENT to George Tomlinson Bousfield, of Sussex Place, Lough-
boro Road, Brixton, in the County of Surrey, for the Invention of
*** IMPROVEMENTS IN POWER-LOOMS.-A communication.
Sealed the 25th July 1856, and dated the 26th February 1856.
PROVISIONAL SPECIFICATION left by the said George Tomlinson Bous-
field at the Office of the Commissioners of Patents, with his. Petition, on
the 26th February 1856.
I, GEORGE TOMLINSON BOUSFIELD; of Sussex Place, Loughboro Road,
Brixton, in the County of Surrey, do hereby declare the nature of the Inven-
tion for "IMPROVEMENTS IN POWER-LOOMS" to be as follows:-
These improvements relate to driving and stopping power looms, and' are-
particularly applicable to looms driven by friction cones. The nature..
of the improvements consists in detaching the balance-wlieel from the
driving shaft, and connecting it with or adding its equivalent in weight to
the belt cone for driving the loom, thus causing the said balance-wheel to be
kept in motion by the belt when the loom is at rest, whereby the power
required to start the loom, and the shock consequent upon stopping it, are
diminished; for when said balance-wheel is affixed to the driving shaft, as
heretofore done, its inertia has to be overcome when the loom is started, and
its momentum counteracted when the loom is stopped, whereas, by the

page_text: improved mode, the balance-wheel, by being kept in motion when the loom is
thrown out of gear, has no tendency to throw the loom forward and increase
the shock in arresting it, nor does it offer any resistance when the loom is
thrown into gear, but, on the contrary, its momentum contributes to put the
loom in motion.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Tomlinson Bousfield in the Great Seal Patent Office
on the 11th August 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
TOMLINSON BOUSFIELD, of Sussex Place, Loughboro' Road, Brixton, in the
County of Surrey, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of February, in the year of our
Lord One thousand eight hundred and fifty-six, in the nineteenth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said George Tomlinson Bousfield, Her special licence that I, the said
George Tomlinson Bousfield, my executors, administrators, and assigns, or such
others as I, the said George Tomlinson Bousfield, 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 "IMPROVEMENTS IN POWER-LOOMS," (a communication,) upon the condition
(amongst others) that I, the said George Tomlinson Bousfield, 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 George Tomlinson Bousfield, do hereby
declare the nature of the said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say:-
These improvements relate to driving and stopping power-looms, and are
particularly applicable to looms driven by friction cones. The nature of the

page_text: improvements consists in detaching the balance wheel from the driving shaft,
and connecting it with or adding its equivalent in weight to the belt cone for
driving the loom, thus causing the said balance-wheel to be kept in motion by
the belt when the loom is at rest; whereby the power required to start the loom,
and the shock consequent upon stopping it, are diminished; for when the said
balance wheel is affixed to the driving shaft, as heretofore done, its inertia has
to be overcome when the loom is started, and its momentum counteracted when
the loom is stopped, whereas, by the improved mode, the balance-wheel, by
being kept in motion when the loom is thrown out of gear, has no tendency to
throw the loom forward and increase the shock in arresting it, nor does it offer
any resistance when the loom is thrown into gear, but, on the contrary, its
momentum contributes to put the loom in motion.
And in order that the said Invention may be most fully understood and
readily carried into effect, I will proceed to describe the Drawing hereunto
annexed.
DESCRIPTION OF THE DRAWING.
Figure 1 is an end elevation of a loom to which the improvements are
applied; Figure 2 is so much of a front elevation of the loom, and Figure 3
so much of a plan thereof, as is necessary to exemplify said improvements;
and Figures 4 and 5 are sections of the driving apparatus and balance-wheel.
a, a, represents the frame of the loom; b, the cam shaft; and c, the lathe
shaft. A friction cone d is affixed to the lathe shaft c, and a belt cone e with
the balance wheel of connected with it turns loosely on said lathe shaft c.
These cones are represented in section in Figure 4, the face of the friction
cone d being covered with leather, as represented by the colored lines g, to
increase their adhesion when brought into action. The balance-wheel ƒ may
be formed so as to constitute the belt surface of the belt. cone, as represented
in Figure 4; or it may extend out from the belt surface of said belt cone, as
represented in Figure 5. h, h, are projections, to prevent the oil from passing
from the lathe shaft to the leather g. The belt cone e, with which the balance-
wheel is connected, is kept constantly in motion by the belt which drives the
loom, said belt cone being pressed against said friction conc d to operate the
loom, and withdrawn from it to stop the loom, so that the balance-wheel, while
it aids both in starting and running the loom, offers no impediment to its being
suddenly arrested. The belt cone e is brought into action and withdrawn from
the friction cone d by the shipping lever i, which is connected with the shipper j
in the usual manner. A friction brake for arresting the loom when thrown
out of gear may be applied to the friction cone d, either to the outside of the

page_text: flange.k, formed as represented in Figure 4, or to the inside of the flange 1,
formed as represented. in Figure 5. The friction brake for arresting the
motion of the loom when thrown out of gear may be applied and brought into
action by the loom shipper, as represented in the Drawings, or it
brought into action by the frog on the protecting rod in the usual way.

In witness whereof, I, the said George Tomlinson Bousfield, have here-
unto set my hand and seal, this Thirtieth day of July, in the year of
our Lord One thousand eight hundred and fifty-six.
