Weaving Two or More Pieces of Fabrio.
I, HENRY ROBERT LISTER, of Ashbrow Mills, Huddersfield, Yorkshire, Manu-
facturer, do hereby declare the nature of this invention to be as follows:-
This invention refers to a new or improved construction and arrangement of loom
for weaving, the object of which is to weave two, three, or four pieces simultaneously
in one loom.
In order to carry out my invention, I emply two, three, or more ordinary slays or
reeds of suitable length, which said slays or reeds are placed side by side in a flat
horizontal position, connected to suitable framework, which is capable of being raised
and lowered by means of a rod, one end of which is connected to the underside of the
aforesaid framework, and the opposite end thereof connected to the crank shaft of the
loom, the said rising and falling framework answering the same purposes as the slay or
going part" of an ordinary loom, for beating up the woft. Each slay has its own
complement of healds and shuttle. boxes, the former of which I place in a flat horizontal
position under the "going part," the said healds being operated by suitable tappets or
cams, through the medium of levers, rods, cords, or chains, whilst I place the shuttle
boxes at each end of and opposite the corresponding slay or reeds, which consequently
form the shuttle races over which the shuttles traverse when sent from one end of the
loom to the other. The picking sticks for throwing the shuttles across the loom pass
through openings made in the rising and falling shuttle boxes, the said picking stick.
being operated by any suitable arrangement of cams or tappets.
The parts so far described form the main features of my invention, and occupy a
central position in my improved loom. The warp beams are placed in suitable positions
at the back of the loom, whilst the cloth beams may all be placed at the front of the
loom; but when weaving three pieces in one loom I prefer that only two cloth beams
should be in front of the loom, one placed at a higher altitude than the other, and the
third cloth beam placed at the back of the loom, and with this arrangement the weaver
can, without difficulty, see each piece as it is being woven.

page_text: The threads of warp from each warp beam are passed through their respective healds
and reeds, and secured in the ordinary manner to one end of each piece of canvas
connected with the warp beams, the "sheds" through which the shuttles are
sent being thereby formed above each slay, whereby the pieces will be woven
vertically.
The "going part" or rising and falling framework is so timed and operated that
when the picks are delivered for each piece being woven, the slay is at its lowest
position, but immediately the picks are delivered, the slay commences to rise, and
brings the reeds thereon against the shoots of weft last delivered, beating or forcing
them upwards against the pieces; the said slays afterwards descending to allow for
another series of picks being delivered, which are beaten up in like manner, and this
continues until the warp has been used up.
Suitable devices may be attached to my improved loom for detecting the absence of
weft and stopping the loom; or ordinary weft stop motions suitably arranged and
connected with the knocking off lever may be employed.
By employing two, three, or more slays, and laying them flat horizontally side by
side upon a rising and falling "slay," with their complement of healds and correlative
parts, operated by means herein described or by equivalent mechanical contrivances, I
am enabled to make a loom which is capable of weaving two, three, or four pieces of
cloth simultaneously, whereby I considerably increase the capacity for producing
woven fabrics in the same amount of time, whilst the cost of weaving is considerably
reduced.
My improved loom has also this further advantage, that it does not occupy much
more space than an ordinary loom.

page_text: I, HENRY ROBERT LISTER, of Ashbrow Mills, Huddersfield, Yorkshire, Manu-
facturer, do hereby declare the nature of this invention and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement:-
This invention refers to a new or improved construction and arrangement of loom
for weaving, the object of which is to weave one piece, or two or three pieces,
simultaneously in one loom.
Such being the nature and object of my invention, I will now proceed to
describe the same more fully, reference being had to the accompanying sheets of
drawings.
Fig. 1 is front elevation of my improved loom, and Fig. 2 cross section of same
taken through line 1—2.
A is the main or tappet shaft of the loom, supported in bearings in the framework B
and carrying fast and loose pulleys at C. On the said shaft Care also mounted two
bevel wheels D and E, gearing with other bevel wheels D' and E' secured on the
crank shafts D and E', which are arranged at right angles to the shaft A and extend
down each side of the loom being supported by the bearings a.
The shafts D' and E'
are cranked in two places, and connected to these cranks are connecting rods or
arms b, b, and c, c, which are secured at their upper ends to brackets bolted to the
underside of the slay board or "going part" F, so that when rotary motion is com-
municated from shaft A to the crank shafts D' and E³, an equal beat or regular up and
down motion is given to the slay board or going part F, the ends of which slide in
suitable grooves or guides formed in the framework B.
The slay board or going part F is provided with two or three slays or reeds d, e, f,
placed side by side in a horizontal position near the upper surface of the slay
board, and these slays or reeds form the shuttle races over which the shuttles g
travel when sent by the picker from side to side of the loom. h are the shuttle
boxes secured to the upper side of the slay board and placed at each end of and
opposite to each slay or reed, as will be more clearly seen in plan view of the
slay board at Fig. 5. i and represent the two series of picking sticks, one

series on each side of the loom, such said picking sticks being centred under the
loom upon the studs and supported in brackets and and working through
slots (see Fig. 5) in the slay board. F, the picking sticks also passing through
the corresponding shuttle boxes and terminating at a point above that to which
the slay board is raised.
The picking sticks are provided with pickers k, which however, are placed
loosely thereon so that they may be carried up and down with the shuttle boxes,
and yet not leave the picking stick. The picking sticks have also loops / con-
nected thereto, through which pass the extremities of the two series of levers m
and n having their fulcrums upon the horizontal rod o. These levers are operated
by cams or tappets m¹ and n¹ respectively, which are mounted on the main shaft A,
and at every revolution of said shaft the cams m¹ and n¹ strike the shoes m' and n³
on said levers, thereby depressing them and causing the picking sticks to rock
upon their fulcrums so as to send the shuttles across the loom. A plan view of
levers m is shewn at Fig. 3. In Fig. 1 the picking sticks i are shewn as having
been operated by the cams m¹ and the three shuttles sent to the other side of
the loom, from whence they will be returned by the opposing picking sticks i¹
when operated by the caus n¹. The cams m' and n' may be arranged and timed
according to the nature and construction of the fabrics to be woven in a similar
manner to that already existent in the ordinary loom. Every pick returns through
its own list, thereby making a complete and perfect list. The healds, shewn at
(one pair only being shewn, for the sake of clearness) are arranged horizontally
one above another under the slay board or going part F, and are supported and
operated by the cords p₁ and p2, the former being passed around the pulley q and
connected to both heald shafts, whilst the latter cords are connected at one end
to the heald shafts, and afterwards passed around the pulleys and ³, and their
opposite ends secured to the lever arms s and t, centred upon the rod o. These
lever arms are operated by cams s¹ and t¹, which, at every revolution of the
shaft A upon which they are mounted, alternately depress their respective levers,
thereby drawing down the cords p and operating the healds p so as to change
the " shed." The warp beam G may be placed in any suitable position, the warp
being unwound therefrom, passed under the several rods u, threaded through the
healds Р and slays or reeds d e f and connected to the canvas attached to the
cloth beams v, vl, and v³, which being arranged somewhat as shewn in Fig. 2, enables
the weaver to see each piece being woven.
The several parts hereinbefore described are so timed and operated that
when the slay board or going part is at its lowest position, as shewn in Figs. 1
and 2, the picking sticks at one side of the loom are operated and a series
of picks delivered, after which the slay board rises and brings the reeds or
slays d, e, f, carried thereby against the shoots of weft thus delivered, beating
or forcing them upwards against the woven pieces w, w¹, and w³, which are thus
woven vertically; the slay board F then descends again and another series of
picks are delivered, which are beaten up in like manner, and this continues until
the warp is used up.
When weaving fancy cloths, the warp beams may be arranged somewhat as
shewn at Fig. 4.
Suitable devices may be attached to my improved loom for detecting the absence
of weft and stopping the loom; or ordinary weft stop motions suitably arranged
and connected with the knocking off lever may be employed.
By employing two or three slays or reeds, and laying them flat horizontally
side by side upon a rising and falling going part, with their complement of healds
and correlative parts, operated by means herein described or by equivalent
mechanical contrivances, I am enabled to make a loom which is capable of weaving
one piece, or two or three pieces of cloth, simultaneously in one loom, whereby
I considerably increase the capacity for producing woven fabrics, in the same
amount of time, whilst the cost of weaving is considerably reduced.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
clain is:
Firstly. The improved construction of loom for simultaneously weaving two or three
pieces of fabric in a vertical position, in manner as described and shewn in the
drawings.
Secondly. The general arrangement and construction of parts forming my
improved loom for simultaneously weaving two or more pieces of cloth in a
vertical position substantially as herein shewn and described.
