CERTAIN IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1853

page_text: LETTERS PATENT to Richard Heyworth, of Cross Hall, near
Chorley, in the County of Lancaster, Manufacturer, and Thomas
Battersby, of Cross Hall aforesaid, Overlooker, for the Invention
Sealed the 19th December 1853, and dated the 26th October 1853.
PROVISIONAL SPECIFICATION left by the said Richard Heyworth
and Thomas Battersby at the Office of the Commissioners of
Patents, with their Petition, on the 26th October 1853.
We, RICHARD HEYWORTH, of Cross Hall, near Chorley, in the
County of Lancaster, Manufacturer, and THOMAS BATTERSBY, of Cross
Hall aforesaid, Overlooker, do hereby declare the nature of the said
Invention for CERTAIN IMPROVEMENTS IN LOOMS FOR WEAVING " to be as
follows:-
Our Invention consists in dispensing with the spring swell generally
employed in power looms, and in substituting in its stead a feeling
finger, which is fixed to the stop rod underneath the lay bottom. To
the stop rod is also fixed a lever, the upper end of which is connected
to one of the connecting arms by which the lay is moved to and fro;
by this means the stop rod is made to vibrate in its bearings, and the
motion is given to it at the proper time for moving the feeling fingers
out of the way when the shuttle enters the box and when the picking

page_text: stick acts on the shuttle. The object of our Invention is to diminish
the power required for picking the shuttle, and to reduce the wear and
tear in the shuttles, pickers, picking straps, and other parts connected
with the picking motion.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Richard Heyworth and Thomas Battersby in the
Great Seal Patent Office, on the 25th April 1854. ..
TO ALL TO WHOM THESE PRESENTS SHALL COME, we,
RICHARD HEYWORTH, of Cross Hall, near Chorley, in the County of
Lancaster, Manufacturer, and -THOMAS BATTERSBY, of Cross Hall afore-
said, Overlooker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the. Twenty-sixth day of October, in the
year of our Lord One thousand eight hundred and fifty-three, in the
seventeenth year of Her reign, did, for Herself, Her heirs and succes-
sors, give and grant unto us, the said Richard Heyworth and Thomas
Battersby, Her special license that, we, the said Richard Heyworth
and Thomas Battersby, our executors, administrators, and assigns, or
such others as we, the said Richard Heyworth and Thomas Battersby,
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 "CER-
TAIN IMPROVEMENTS IN LOOMS FOR WEAVING," upon the condition (amongst
others) that we, the said Richard Heyworth and Thomas Battersby, by
an instrument in writing under our hands and seals, or under the hand
and seal of either 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 montlis.next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that we, the said Richard Heyworth and Thomas
Battersby, do hereby declare the nature of our said Invention, and in

page_text: what manner the same is to be performed, to be particularly described:
and ascertained-in and by the following statement, that is to say
Our Invention consists in dispensing, with, the, springs, usually.'em-
ployed for acting on the swells by which the shuttle is held in, the
shuttle box, and in substituting an improved combination of parts in
their stead. And in order that our Invention may be fully understood.
and readily carried into effect, we will proceed to describe the means
pursued by us, reference being had to the accompanyings Drawings, and
the letters and figures marked thereon.
DESCRIPTION OF THE DRAWING.
Figure 1, is a side elevation of part of a loom to which one mode of
applying our improvements is attached Figure. 2, is a plan; and
Figure 3, a front view of the same. , is the loom side; b, the.crank
shaft; c, the lay bottom; d, the lay sword; e, the stop rod; e, the stop
finger; the frog; g, the connecting arm; and, the swell. "All these
parts. are made in the usual manner: To the stop rod e, is fixed a
lever i, the upper end of which is acted upon by a connecting strap 2,
fixed to the cotter g of the connecting arm g, or by any other convenient
part of the connecting arm or crank shaft. k, is: a short lever also fixed
to the stop rod. This lever is acted upon by the spring 1, the lower end.
of which fits on a stud projecting from the lay sword. m, is a feeling
finger fixed to the stop.rode; another similar finger is fixed to the
other end of the stop rod, which is not shown in the Drawing. The
mode of the operation is as follows:
The Drawing represents the lay close up to the cloth; the strap on
the cotter g' is now acting on the lever i, which, by overcoming the
resistance of the spring I, raises the stop finger.cl over the frog f.:
during the advancing of the lay, and at the same time the feeling
fingers m are held beyond the reach of the swells h, thereby liberating
the shuttle which had previously been held by the action of the spring;
the crank shaft in revolving gradually draws the lay back, at the same
time that the warps are opened to form the shed; the shuttle is then
picked across from one shuttle box to the other in the ordinary manner;
the feeling fingers m, being still held beyond the reach of the swells h,
allow the shuttle to leave one box and enter the other without having

page_text: overcome the resistance of the springs, and to raise the stop finger
over the frog, as in looms of the ordinary construction; but as soon
as the crank turns the centre, as shewn by dotted lines in Figure 1
the cotter g¹ ceases to act on the lever i, and the spring is at
liberty to draw the feeling fingers m against the swells h, one of
which then comes against the shuttle and prevents it from rebounding.
When the lay again advances towards the cloth the cotter g¹ acts on
the lever i, at the proper time for raising the stop finger e¹ over the
rog, as before described. The object of our Invention is to remove
the pressure of the swell from the shuttle when the picking motion
comes into operation and when the shuttle enters the box, whereby less
ower is required for working the loom, and less injury is done to
the shuttles, pickers, picking straps, and other parts connected with
the picking motion,' than in looms of the ordinary construction.
Having thus described the nature of our Invention, and the manner
of performing the same, we wish it to be understood that we do not limit
ourselves to the precise details herein set forth, as the same may be
varied without departing from the peculiar character of our Invention ;
but what we do claim is, removing the pressure from the shuttle when
it is picked, and when it enters the shuttle box, as herein-before shewn
and described.
In. witness whereof, we, the said Richard Heyworth and Thomas
Battersby, have hereunto set our hands and seals, this Twenty-.
fourth day of April, One thousand eight hundred and fifty-four.
