AN IMPROVEMENT IN OR APPLICABLE TO POWER Looms
Year: 1855

page_text: LETTERS PATENT to William Madeley, of the City of Manchester, i
in
the County of Lancaster, Machinist, and Thomas Hanlon, of the same
Place, Mechanic, for the Invention of "AN IMPROVEMENT IN OR APPLICABLE
TO POWER Looms."
Sealed the 3rd July 1855, and dated the 18th April 1855.
PROVISIONAL SPECIFICATION left by the said William Madeley and
Thomas Hanlon at the Office of the Commissioners of. Patents,, with
their Petition, on the 18th April 1855.
We, WILLIAM MADELEY, of the City of Manchester, in the County of
Lancaster, Machinist, and THOMAS HANLON, of the same Place, Mechanic,
do hereby declare the nature of the Invention for "AN IMPROVEMENT IN OR
APPLICABLE TO POWER LOOMS" to be as follows:-
Our Invention consists in a new or improved apparatus for relieving the
shuttle, immediately before it receives the impelling blow of the picking rod,
from the pressure of the spring or swell commonly used in the shuttle boxes of
power looms, for preventing the shuttle when driven home at each pick from
rebounding or leaving the shuttle box before receiving the next stroke of the
picking rod.
Our improved apparatus consists of a lever mounted on a suitable stud or
fulcrum, and one end of which lever is placed under the ordinary stop piece

page_text: of the stop rod of the loom, and the other end is placed so as to be acted
upon by a stud or piece which descends and rises with each revolution of the
crank by which the lathe or batten is driven. As the crank revolves, at each
pick of the loom this stud or piece depresses the adjacent end of the lever,
and thereby raises the other end, which lifts up the stop piece and partially
turns the stop rod, the finger on which pressed the spring or swell of the
shuttle box against the shuttle. The turning of the stop rod removes the
finger from its bearing against the spring or swell, which consequently ceases
to press on the shuttle, and the shuttle is left at liberty to obey the stroke of
the picking rod without the latter having to overcome the resistance of the
swell or spring, by which means a saving in power, time, and wear of parts is
effected.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Madeley and Thomas Hanlon in the Great Seal
Patent Office on the 17th October 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
MADELEY, of the City of Manchester, in the County of Lancaster, Machinist,
and THOMAS HANLON, of the same Place, Mechanic, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria did, by Her Letters
Patent under the Great Seal of the United Kingdom of Great Britain and
Ireland, bearing date the Eighteenth day of April, One thousand eight hundred
and fifty-five, in the eighteenth year of Her reign, give and grant unto us, our
executors, administrators, and assigns, Her especial license, full power, sole
privilege and authority, that we, the said William Madeley and Thomas
.Hanlon, our executors, administrators, and assigns, should and lawfully might,
:during the term of fourteen years therein expressed, make, use, exercise, and
vend, within Her said Majesty's United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, our Invention of "AN
IMPROVEMENT IN OR APPLICABLE TO POWER LOOMS;" in which said Letters Patent
is contained a proviso, that if we, the said William Madeley and Thomas
Hanlon, should not particularly describe and ascertain the nature of the said
Invention, and in what manner the same is to be performed, by an instrument
in writing under our hands and seals, or under the hand and seal of one of
us, 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

page_text: Patent, then the said Letters Patent, and all liberties and advantages whatso-
ever thereby granted, should utterly cease, determine, and become void, as in
and by the same, relation being thereunto had, will more fully and at large
appear.
NOW KNOW YE, that in compliance with the said proviso, we, the said
William Madeley and Thomas Hanlon, hereby declare that the nature of
our said Invention, and the manner in which the same is to be performed,
are particularly described and ascertained in and by the following statement
and description, reference being had to the Drawings on one Sheet hereunto
annexed, and in which description and Drawings the same letters and
numbers of reference are used to indicate the same or corresponding parts in
the several Figures in which they occur:-
Our Invention consists in a new or improved apparatus for relieving the
shuttle, immediately before it receives the impelling blow of the picking rod,
from the pressure of the swell commonly used in the shuttle boxes of power
looms, for preventing the shuttle when driven home at each pick from
rebounding or leaving the shuttle box before receiving the next stroke of the
picking rod.
We shall now proceed to describe our apparatus with reference to the
Drawings, in which Figure 1 is a plan, and Figure 2 is an elevation, of such
parts of a loom with our apparatus as are requisite to be shewn for the
explanation of our Invention. The Drawings are made to a scale of half
the full size.
A is the crank arm, and B the lathe arm; C is the stop rod, on which are
fixed the stop piece D and the stop rod finger E; and F is part of a side frame
of the loom; all of which parts are well known and in general use. The bent
lever G is mounted on the stud H, placed in a slot in the side frame F; and on
the stud I, placed in a slot in the crank arm A, is the bowl J. The lever G
is so formed that one end will pass under the stop piece D and be in contact
with it, and the other under the bowl J, and so as to be acted upon by it at
the time; herein-after described. When the loom is in operation, the crank
revolves and gives motion to the crank arm A. The stud I must be so placed,
that as the crank arm descends, the bowl J, immediately before the shuttle
receives the impelling blow of the picking rod, will come in contact with the
adjacent end of the lever G and depress it, thereby raising the other end,
which lifts up the stop piece D, and partially turns the stop rod C with the
finger E. The turning of the stop rod removes the finger E from bearing
against the swell in the shuttle box, which consequently ceases to press on the
shuttle, and leaves it at liberty to obey the stroke of the picking rod without

page_text: the latter having to overcome the resistance of the swell. The studs Hand I
are placed in slots to admit of the adjustment of their respective positions so
as to ensure the precise action of the. lever G at the required time, By
making the end of the lever G, against which the bowl J comes in contact,.
long enough for the bowl to continue to act against it until the shuttle. has
arrived in the opposite shuttle box to that from which it was thrown, the
pressure of the finger E against the swell will not only be taken off at the time
of picking, but will also be kept off until the shuttle has arrived in the oppo-
site box, at which time the bowl J should pass off the end of the lever G,
and allow the finger E at once to be drawn against the swell, and press against
the shuttle, in the ordinary way.
Having now described the nature of our said Invention, and the manner
in which the same is to be performed, we declare. that. we claim as of our
Invention, the application of a lever acted upon by.or from the crank arm,
which lever, acting upon the stop piece as herein-before described, relieves the
shuttle, immediately before it receives the blow of the picking rod, from the
pressure of the swell or part which tends. to retain it in. the shuttle box.
In witness whereof, we, the said William Madeley and Thomas
Hanlon, have hereunto set our hands and seals, the Sixteenth day
of October, in the year of our Lord One thousand eight hundred and
fifty-five
WILLIAM MADELEY. (L.S.)
THOMAS HANLON.
Signed, Sealed, and delivered by the said William
Madeley and Thomas Hanlon, in the presence of
JOHN P. ASTON, Attorney,
Manchester.
