IMPROVEMENTS IN LOOMS FOR WEAVING NARROW FABRICS
Year: 1870

page_text: LETTERS PATENT to Samuel Cunliffe Lister, of Bradford, in the
County of York, Manufacturer, for the Invention of “IMPROVEMENTS
IN LOOMS FOR WEAVING NARROW FABRICS."
Sealed the 23rd May 1871, and dated the 17th December 1870.
PROVISIONAL SPECIFICATION left by the said Samuel Cunliffe Lister
at the Office of the Commissioners of Patents, with his Petition,
on the 17th December 1870.
I, SAMUEL CUNLIFFE LISTER, of Bradford, in the County of York,
Manufacturer, do hereby declare the nature of the said Invention for
“IMPROVEMENTS IN LOOMS FOR WEAVING NARROW FABRICS," to be as follows:-
The object of this Invention is to provide a means for quickly inserting
weft into the shed each time it is opened.
In the Specification of a former Patent granted to me on the Ninth
day of April, One thousand eight hundred and seventy (No. 1054) I
described an arrangement of apparatus for passing a shuttle through a
loop of weft that had been carried across the shed by a weft carrier.
In this arrangement the shuttle was pushed endwise by pushers alter-
nately from one peg to another, the two pegs being placed end to end,
with a space between the two..

page_text: According to my present Invention I employ when weaving narrow
fabrics a similar arrangement of apparatus for passing a shuttle through
the shed, one of the pegs being placed on one side of the shed, and the
other peg on the opposite side, and the shuttle being moved across the
shed from one peg to another by means of pushers, as described in the
before-mentioned Specification. In this arrangement the shuttle should
be somewhat longer than the distance between the pegs. If it be
desired to use a shorter shuttle each peg may, as the shuttle carried by
it is being moved forward by its pusher, also move forward with the
pusher partly into the shed until it has delivered the shuttle on to the
opposite peg, which may at this time be stationary, and when the pusher
has completed the delivery of the shuttle on to the stationary peg, the
pusher with its peg both retire, or in place of the peg which has to
receive the shuttle remaining stationary whilst the shuttle is moved
across the shed, it may move forward to meet the shuttle and again
retire as soon as the shuttle has been delivered on to it. In place of
the supports for the shuttle which are on the two opposite sides of the
sled being composed of pegs, other forms of support may be employed
and the shuttle may similarly be pushed across the shed from one to the
other by means of pushers as above described. Two pegs moving
alternately to and from one another may also be employed. The shuttle
on the end of one peg being moved partly across the shed and delivered
by it on to the end of the opposite peg, which then retires and carries
it back beyond the warps after the weft has been beaten up, the peg
carrying the shuttle again moves forward and delivers it to the opposite
peg, and so on in succession. The tension of the weft may be regulated
either in the ways described in the Specification before mentioned for
regulating the tension of the thread of the vertical shuttle or in other
suitable manner.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Samuel Cunliffe Lister in the Great Seal Patent
Office on the 17th June 1871.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventeenth day of December, in the
year of our Lord One thousand eight hundred and seventy, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Samuel Cunliffe Lister, Her special license
that I, the said Samuel Cunliffe Lister, my executors, administrators,
and assigns, or such others as I, the said Samuel Cunliffe Lister, 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
LOOMS FOR WEAVING NARROW FABRICS," upon the condition (amongst others)
that I, the said Samuel Cunliffe Lister, 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 Samuel Cunliffe Lister, 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 :—
The object of this Invention is to provide a means for quickly inserting
weft into the shed each time it is opened.
In the Specification of a former Patent granted to me on the Ninth
day of April One thousand eight hundred and seventy (No. 1054) I
described an arrangement of apparatus for passing a shuttle through a
loop of weft that had been carried across the shed by a weft carrier. In
this arrangement the shuttle was pushed endwise by pushers alternately
from one peg to another, the two pegs being placed end to end with a
space between the two.
According to my present Invention I employ when weaving narrow
fabrics a similar arrangement of apparatus for passing a shuttle through
the shed, one of the pegs being placed on one side of the shed and the
other
peg 'on the opposite side, and the shuttle being moved across the
shed from one peg to another by means of pushers as described in the

page_text: before mentioned Specification. In this arrangement the shuttle should
be somewhat longer than the distance between the pegs. If it be desired
to use a shorter shuttle, each peg may, as the shuttle carried by it is being
moved forward by its pusher, also move forward with the pusher partly
into the shed until it has delivered the shuttle on to the opposite peg,
which may at this time be stationary, and when the pusher has com-
pleted the delivery of the shuttle on to the stationary peg, the pusher
with its peg both retire. Or in place of the peg which has to receive
the shuttle remaining stationary whilst the shuttle is moved across the
shed it may move forward to meet the shuttle and again retire as soon
as the shuttle has been delivered on to it. In place of the supports for
the shuttle which are on the two opposite sides of the shed being com-
posed of pegs, other forms of support may be employed, and the shuttle
may similarly be pushed across the shed from one to the other by means
of pushers as above described. The tension of the weft may be regulated
either in the ways described in the Specification before mentioned for
regulating the tension of the thread of the vertical shuttle or in other
suitable manner.
In the Drawings hereunto annexed I have shewn the manner in which
I prefer to carry out my Invention.
Figure 1 is a vertical transverse section; Figure 2 a horizontal
section, and Figure 3 a vertical longitudinal section of so much of a
loom as is necessary for shewing my improvements.
In the arrangement shewn in the Drawing the peg which carries the
shuttle and the pusher both move forward simultaneously into the shed,
and the pusher then delivers the shuttle on to the opposite peg which at
this time is stationary. The peg and pusher which carried the shuttle
across the shed then both retire to their original positions. a, a, are
the pegs which are slightly oval in section, at their forward ends and
carry springs a* which are to press against the interior of the shuttle
and retain it. The back ends of the pegs pass through fixed tubular
guides b. Within the tubes bare springs c which tend to press the
pegs into their forward position across the shed; a¹ is a pin passed
through the peg and through slots in the tube, and serves as a stop to
limit the peg's motion.
A longitudinal section of these parts is shewn separately at Figure 4;
d are the pushers capable of sliding to and fro on the pegs; projecting
from each pusher are pins d'embraced by a fork e by which a to-and-fro

page_text: motion is imparted to them. When the pusher is moved forward its
peg moves forward with it, being pushed forward by the spring c until
it is stopped by the pins a¹. The pusher then continues its forward
movement until it has delivered the shuttle i on to the opposite peg,
which, as before stated, is at this time stationary. The pusher then
retires and carries back with it the peg to its former position, the beat
up then takes place, and the same operation is repeated.
The form of shuttle I prefer to employ is shewn full size at Figure 5,
for the most part it is similar to the shuttle described in the Specification
before mentioned, it is however so constructed as to put tension on to
the weft in the manner described in the Provisional Specification lodged
by me on the 29th December 1870, No. 3389. This is effected by metal
plates m being pressed by the spiral springs m¹ against the periphery of
the bobbin. Other arrangements for putting tension on the weft may
however be adopted as before stated. The to-and-fro motion is given
in the following manner to the forks e which operate the pushers :-The
forks are at the upper ends of arms which turn on fixed studs f, near
the lower end of each arm is a slot into which enters a stud carried by
a slide bar f¹ which can move to and fro in guides, as shewn. There is
a separate slide bar for each fork and each bar is moved to and fro at
the required time by a double cam g, acting on rollers carried by it.
Each double cam is carried by an axis h, and the two axes h are geared
one with the other by the toothed wheels h¹, so that they both revolve
at equal speeds. One of the shafts his driven as shewn from the cam
shaft of the loom, which also carries the cams for the shedding motions.
The batten is worked to and fro by a cam on the driving shaft, which, as
is usual, is arranged to make two revolutions for one revolution of the
cam shaft.
The loom shewn in the Drawing is arranged for weaving one narrow
fabric only, it will however be evident that by prolonging the slide
bars f, so that a number of shuttles may be worked by them, the loom
may be arranged to weave several narrow fabrics at one time.
Other arrangements of mechanism for working the pegs and pushers
may also be adopted and the manner of working the pegs and pushers
may also be varied, as herein-before stated.
Having thus described the nature of my Invention and the manner
in which I prefer to carry the same into effect, I would have it under-
stood that what I claim as my improvements in looms for weaving

page_text: narrow fabrics is, the combined arrangements substantially as herein
described of pegs and pushers for passing a shuttle to and fro through
the shed opened in the warps.
In witness whereof, I, the said Samuel Cunliffe Lister, have hereunto
set my hand and seal, this Sixteenth day of June, in the year of 5
our Lord One thousand eight hundred and seventy-one.
