and in Apparatus Employed for such Purpose.
We HENRY BROOKS BROADHURST of 56 Mosley Street Manchester Merchant, and
EDWIN SMITH of Ten Acres Mill Newton Heath, Manager, both in the County of
Lancaster do hereby declare the nature of this invention to be as follows:-
These improvements relate to the manufacture of that class of fancy piled fabrics
which are woven simultaneously two pieces face to face, the two fabrics being united
together by the pile warp threads which when the two pieces are severed or cut
asunder form the pile on the face of the two pieces, the object of the invention
being to obtain a combination of piled fabrics of one or more colors with checked
grounds of any desired description and of the same or different colors; this being
a new kind of fabric never before produced.
This we propose to effect by means of a double set of healds or harness so actuated
that the two pieces are woven together with a pile warp or warps passing from one
fabric to the other and interweaving with both, in combination with either a
revolving shuttle box, a drop box, or other multipe weaving shuttle apparatus
whereby we are enabled to use various colors of weft so as to produce varied
colored stripes across the fabrics, at the same time that we weave the double fabric
having a continuous or intermittent fancy pile on the surface of each.
We employ two yarn beams for the main warps of the two fabrics and one for the
pile warp of both, and for letting off the pile warp so as to produce the desired effect
we pass the same partly round and between two rollers covered with india rubber
cloth with their circumferences in contact, one of which is actuated by the following
means, and the other revolves by friction of contact merely. The driven roller has
a fine toothed ratchet wheel fixed on one end of its axis, in the teeth of which works
a ratchet or pawl carried by a long letting off lever the fulcrum of which is the
axis of the roller, and the other end is connected by a cord attached to and worked
by one of the hooks of the Jacquard or other pattern producing machine.
When this book is drawn up it raises the letting off lever causing the ratchet to
over run a certain number of teeth, and when this hook is released the weight of the

page_text: lever or an applied spring causes it to fall and its other end rising pushes the
ratchet wheel round and rotates the letting off roller so as to give off the required
length of pile warp.
The cutting asunder of the two fabrics may be performed by means of a knife
travelling to and fro, or continuously in one direction by a band, or by any suitable
and well known method either in the loom during the operation of weaving or apart
therefrom after the weaving is completed.
Wo prefer however to cut the fabrics asunder in the loom during the process of
weaving, by means of a knife drawn to and fro by means of a cord, the two ends
of which are attached to a drum or wheel which we cause to perform a portion of a
revolution in each direction alternately by the following means.
On the axle at one side of the drum or wheel we key or fix a toothed pinion into
which gears a toothe quadrant fixed to one end of a lever. The other end of a lever
works on a fixed stud or fulcrum, and at or about the centre of the lever carries a
roller or bowl which runs in the groove in a revolving cam.
The form of this groove
is such as to give the requisite up and down motion to the lever which by means of
the toothed quadrant and pinion imparts such an alternate revolving motion to the
drum or wheel as will cause the cord or band to draw the knife to and fro across
the loom.

page_text: Improvements in Weaving and Cutting Fancy Double Piled Fabrics
and in Apparatus Employed for such Purpose.
We HENRY BROOKS BROADHURST of 6 Mosley Street Manchester Merchant, and
EDWIN SMITH of Ten Acres Mill Newton Heath Manager, both in the County of
Lancaster 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:-
These improvements relate to the manufacture of that class of fancy piled fabrics
which are woven simultaneously two pieces face to face the two fabrics being united
together by the pile warp threads which, when the two pieces are severed or cut
asunder form the pile on the face of the two pieces, the object of the invention being
to obtain a combination of piled fabrics of one or more colors with checked grounds
of any desired description and of the same or different colors, this being a new kind
of fabric never before produced.
The nature of our said invention will be readily understood on reference to the
annexed drawing and the following explanation thereof.
Fig. 1. on the drawing represents in sectional elevation so much of a loom as is
necessary to illustrate our invention, a, a being part of the framing of the loom,
b, b and c, c the yarn beams for the main warps and d, d the yarn beam for the
pile warp.
For the purposes of our invention we use a double set of healds or harness so
actuated that the two pieces are woven together with a pile warp or warps passing
from one fabric to the other and interweaving with both, in combination with either
a revolving shuttle box, a drop box or other multiple weaving shuttle apparatus
whereby we are enabled to use various colors of weft so as to produce varied colored
stripes across the fabrics, at the same time that we weave the double fabric having a
continuous or intermittent fancy pile on the surface of each.
We employ two yarn beams b, b and c, c for the main warps of the two fabrics and
one beam d, d for the pile warp of both and for letting off the pile warp so as to
produce the desired effect we pass the same partly round and between two rollers e, e¹
covered with india rubber cloth or other suitable material with their circumferences
in contact, one of which e is actuated by the following means, and the other e¹ revolves,
by friction of contact merely.
The driven roller e has a fine toothed ratchet wheel f,ffixed on one end of its axis,
in the teeth of which works a ratchet or pawl g, carried by a long letting off
lever h, the fulcrum of which is the axis of the roller e and the other end is con-
nected by a cord attached to and worked by one of the books of the Jacquard or
other pattern producing machine.
9.9
When this hook is drawn up it raises the letting off lever h, causing the ratchet
to over-run a certain number of teeth, and when this hook is released the weight of
the lever or an applied spring causes it to fall, and its other end rising pushes the

page_text: ratchet wheel, round and rotates the letting off roller e so as to give off the
required length of pile warp.
The cutting asunder of the two fabrics may be performed by means of a knife
travelling to and fro, or continuously in one direction by a band, or by any suitable
and well known method either in the loom during the operation of weaving or apart
therefrom after the weaving is completed.
We prefer however to cut the fabrics asunder in the loom during the process of
weaving, by means of a knife drawn to and fro by means of a cord the two ends of
which are attached to a drum or wheel i, i Fig. 2 which we cause to perform a portion
of a revolution in each direction alternately by the following means.
On the axle at one side of the drum or wheel i, i we key or fix a toothed pinion k, k
into which gears a toothed quadrant 1, 1 fixed to one end of a lever m, m. The other
end of this lever works on a fixed stud or fulcrum n and at or about the centre,
the lever carries a roller or bowl o, o which runs in the groove in a revolving
cam P, P.
The form of this groove is such as to give the requisite up and down motion to the
lever m, m which by means of the toothed quadrant l, and pinion k, k imparts such
an alternato revolving motion to the drum or wheel i,i as will cause the cord or band j,j
to draw the knife to and fro across the loom.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
In the manufacture of that class of fancy piled fabrics which are woven simul-
taneously two pieces face to face.
First, the combination of piled fabrics of one or more colors with checked grounds
of any required pattern and of the same or different colors substantially as herein-
before described.
Secondly we claim as a new manufacture the fancy double piled checked fabrics
woven as above described.
Thirdly we claim the apparatus hereinbefore described and illustrated by Fig. 1. of
the annexed drawings for letting off the pile warp in weaving such fabrics, and
Fourthly we claim the particular arrangement of mechanism shown on Fig. 2. ol
the annexed drawings and hereinbefore described for cutting or severing the pile of
such fabrics consisting of a single lever actuated by a grooved cam in combination
with a rack and pinion for actuating the cord which drives the cutting knife.
