IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1864

page_text: LETTERS PATENT to Joseph Edmondson, Manufacturer, and Thomas
Ingram, Manager, both of Frizinghall, near Bradford, in the County
of York, for the Invention of "IMPROVEMENTS IN LOOMS FOR WEAVING."
PROVISIONAL SPECIFICATION left by the said Joseph Edmondson and
Thomas Ingram at the Office of the Commissioners of Patents, with
their Petition, on the 17th March 1864.
We, JOSEPH EDMONDSON, Manufacturer, and THOMAS INGRAM, Manager,
both of Frizinghall, near Bradford, in the County of York, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN LOOMS FOR WEAVING,"
to be as follows:-
The first part of the Invention relates to means of locking or retaining the
shuttles in the boxes, and consist in the application of a lever (to each box
frame) so formed that the picker when driven back by a shuttle from the
other side of the loom will actuate and cause the lever to retain the shuttle by
clipping or pressing against it. An adjustable stop is placed between the
picker and the outer end of the shuttle box to stop the shuttle in any required
position. This apparatus will also operate instead of a check strap.
The second part of our Invention relates to means of supplying weft to
continuous looms, and consists in having a carrier for the weft cases moving
in curved slides, or by preference mounted on the fulcrum of the lathe, so as
to be capable of oscillating in the same arc or curved line as the shuttle boxes,

page_text: and is operated by a connecting rod and a cam or tappet fixed on the tappet
shaft or other shaft of the loom, or on a stud fixed to the frame of the loom.
The weft fork is arranged so as to attach the connecting rod to the weft feeder
when a change of weft is required. The cam or tappet is so formed and set
or adjusted on the shaft as to cause the feeder to commence feeding imme-
diately after the arrival of the shuttle in the box, and to finish before the
shuttle is again driven out, thereby giving time and ease in the changing of
the weft cases.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Edmondson and Thomas Ingram in the Great Seal
Patent Office on the 17th September 1864.
· TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOSEPH
EDMONDSON, Manufacturer, and THOMAS INGRAM, Manager, both of Frizinghall,
near Bradford, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventeenth day of March, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-seventh year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Joseph Edmondson and Thomas Ingram, Her special licence that we, the
said Joseph Edmondson and Thomas Ingram, our executors, administrators,
and assigns, or such others as we, the said Joseph Edmondson and Thomas
Ingram, 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 Joseph
Edmondson and Thomas Ingram, our executors or administrators, by an
instrument in writing under our, or their, or one of our or their hands and
seals, should particularly describe and ascertain the nature of the said In-
vention, 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 we, the said Joseph Edmondson and Thomas
Ingram, do hereby declare the nature of our said Invenion, and in what
manner the same is to be performed, to be particularly described 'and ascer-

page_text: tained in and by the following statement and accompanying Sheet of Drawings
(that is to say) :-
The first part of the Invention relates to means of locking or retaihing the
shuttles in the boxes, and consists in the application of a lever (to each box
frame) so formed that the picker when driven back by a shuttle from the other
side of the loom will actuate and cause the lever to retain the shuttle by
clipping or pressing against it. Au adjustable stop is placed between the
picker and the outer end of the shuttle box to stop the shuttle in any required
position. This apparatus will also operate instead of a check strap.
The second part of our Invention relates to means of supplying weft to
continuous looms, such as are described in the Specifications of Patents,
No. 860, A.D. 1860, and 239, A.D. 1868, granted to the aforesaid Thomas
Ingram and Joseph Edmondson, and consists in having a carrier for the weft
cases mounted on the fulcrum of the lathe, so as to be capable of oscillating
in the same are or curved line as the shuttle boxes, and is operated by a cani
or tappet fixed on the tappet shaft or other shaft of the loom, or on a stud
fixed to the frame of the loom. The cam or tappet is so formed and set or
adjusted on the shaft as to cause the feeder to commence feeding immediately
after the arrival of the shuttle in the box, and to finish before the shuttle is
again driven out, thereby giving time and ease in the changing of the weft
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is an end elevation of a loom with our improvements applied thereto;
and Fig. 2 is part of a front elevation of the same; Fig. 8, a back elevation;
and Fig. 4, a plan of one shuttle box, or one end of the lathe or batten, shewing
the lever for retaining the shuttle in the box and the manner in which it is
operated by the picker, in accordance with the first part our Invention.
A is the lever, which is hinged on stud a fixed to the back of the shuttle
box, one end of this lever is cranked so as to pass through an opening of the
box to the picker B, the other end has attached to it a break or pad C, which
also passes through an opening of the box to the shuttle D. This break is
made to fit on the side of the shuttle when in the box. A spring E is
attached to the back of the box, and presses on the lever so that when the
shuttle is being driven out of the box by the picker the lever will assume the
position shown by dotted lines, and leave room for the shuttle's exit and
re-entrance. The shuttle on entering drives the picker back to the end of the
box, and the picker operates the lever, forcing it into the position shewn i
ull lines, thereby locking the shuttle in the box, until the picker is again

page_text: actuated and liberates the lever. F is the adjustable stop, which is secured
on the picker spindle by a set screw, and may be set so as to stop the shuttle
in any desirable position.
The second part of our Invention is shewn in Figs. 1 and 2, where G is the
lathe or batten carrying the shuttle boxes, being mounted upon a fulcrum H
as usual; I is the carrier for the weft cases, which is fixed to a lever J mounted
on the fulcrum H, so that this carrier is capable of oscillating in the same arc
as the shuttle boxes. On the same fulcrum H is hinged a lever K carrying a
pusher L working between two jaws i, i, of the carrier I (which are shewn on
a larger scale at Figs. 5 and 6). Also on this fulcrum H is a lever M; these
levers J, K, and M, though working on one fulcrum, are free to move thereon
independently of each other. N is a cam or tappet fixed on the low shaft O
hereafter explained; P is a spring connecting the levers M and K, by which
the downward motion of M also actuates K; Q is a break slide attached to M
with its counterpart Q' attached to K. They have dovetails fitting into each
other, and are kept together by an adjustable spring Q working through a
slot in Q. R is a set screw in the lever K with its end abutting against the
short arm of the lever M for the purpose of adjusting their relative positions ;
S is a spring connecting the lever J to a fixing on the lever K through an
opening therein. The lever M is brought back to and retained in a state of
rest after its operation by a spring M². On the end of the lever M, under the
centre of the low shaft O, is attached a bell-crank tumbler T carrying a friction
pulley T¹ to act when required against the surface of the cam or tappet N
fixed on the end of the end of the shaft. When this tumbler is not required
to be acted upon it is held out of contact (as shewn) by a spring T. In the
other arm of this tumbler is a slot, through which is passed a rod U carrying
a nut to prevent its going through the slot farther than is desired, and to give
motion to the tumbler when the pulley T¹ is to be put into gear with the
tappet N. The rod U is actuated by the levers U₁ and Us, the latter having
one end fixed on the shaft U³, which is actuated by the weft fork, and is
ordinarily used to let off the catches which cause the cloth to traverse forward
as it is woven. V is the hopper or rack for holding weft cases, similar to
those described in the Specifications of Patents hereintofore referred to; the
shuttles employed in these improved looms being also similar to those described
in the said Specification. The peculiar form of the cam N is shewn full size
in Figs. 7, 8, and 9..
The operation of the apparatus is as follows:-When the weft breaks or is
exhausted, the weft fork (which is at the end of the loom opposite to the one
shewn in the Drawings) turns the shaft Us in the direction indicated by the

page_text: arrow, which by means of the lever U¹ and U' depresses the rod U, and throws
the pulley T¹ under the cam N. This cam in revolving depresses the lever M
and thereby draws forward the carrier I and pusher L, which convey the
bottom case from the hopper V in time to meet the shuttle when it has arrived
in the shuttle box. The claws or projections on the under side of the carrier I
coming in contact with the batten or slay (as shewn at W, Fig. 5) the carrier
is forced back by the slay, while, owing to the form of the tappet N, the
pusher L is also retreating, but with a motion slower than that of the slay, the
difference of motion being so adjusted as to drive the case off from the jaws of
the carrier into the shuttle; and at the same time to expel the case containing
the broken weft or exhausted spool. The shuttle is then ready to be picked
out of the shuttle box, and the weaving will proceed as before. The carrier
and pusher then fall back into the position of rest and another case drops into
the jaws of the carrier ready to be conveyed to the shuttle when required. At
the same time the "shunt" or incline n on the cam N has driven the tumbler T
out of gear or line of contact with the cam, as shewn in the Drawing, where it
is held by the spring T2 until the weft fork again operates. The carrier is so
adjusted that the jaws or part on which the case rests are lineable, or in a
right line with the bottom of the opening in the shuttle, and as the notion
thereof is in the same arc as the slay, this line is preserved during the whole
time the case is being driven into the shuttle. The tappet N is, by preference,
so formed as to drive in the case so slowly at first as to give a safe entrance,
and then gradually to increase in speed till the operation is complete. Some-
times we give the tappet N such a form as to cause the pusher to follow the⚫
slay as it is retreating from the breast beam, but at a speed greater than that
of the slay, thus prolonging the time for driving in the case.
Having thus described the nature of this our said Invention, and shewn
how the same is to be or may be performed or carried into practical operation,
we would have it distinctly understood that we do not confine ourselves to the
precise details of construction or arrangement of the parts herein shewn and
described, as various modifications may be made therein without departing
from the main features of the Invention; but what we claim as of our Inven-
tion, is,-
Firstly, the method or means herein shewn of locking the shuttle in the
shuttle box by the picker.
Secondly, the application and use of carriers for supplying weft cases to the
shuttles while the lathe is in motion.
.
Thirdly, the arrangement of apparatus for supplying weft cases to shuttles,-

page_text: 'so as to cause them to move in the same arc or line as that in which the
shuttle boxes move.
Fourthly, the construction and use of a cam or tappet in such form and
manner as to produce variations in the relative speed of the lathe, and that of
the apparatus for driving the weft cases into the shuttles.
•
Fifthly, the combination and arrangement of parts or apparatus for the
purposes set forth, in manner substantially as herein described and illustrated
by the accompanying Sheet of Drawings.
In witness whereof, I, the said Joseph Edmondson, for and on behalf of
myself and the said Thomas Ingram, have hereunto set my hand and 1
seal, this Sixteenth day of September, One thousand eight hundred and
sixty-four.
