PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Cut Pile Fabrics.
We, JOHN WIMPENNY, of 49 Carlisle Street, Bradford, in the County of York,
Watchmaker, and DIXON REDSHAW, of 228 Priestman Street, Bradford, aforesaid,
Mechanic, do hereby declare the nature of this invention to be as follows:-
This invention has for its object, the construction of a machine, by which yarn
may be inserted in, and secured to a woven fabric after it has left the loom, and to
cut the yarn in such a manner that, it has the appearance of a pile fabric woven
and cut in the manner as hitherto.
We accomplish our object in the following manner :-In a suitable frame is
mounted a shaft having tappets secured thereon, on the rotation of which, they
operate levers, and thereby cause a bar having a number of sharp pointed pins
projecting vertically, to reciprocate in a somewhat vertical direction, and by
another cam with suitable intermediate connections, the said bar is caused to move
laterally.
On the before mentioned shaft, wheels are secured, which operate discs having
an adjustable pin attached to the face of each, which are respectively coupled by
rods to a needle bar, so that, on the rotation of the discs, the said bar is caused to
reciprocate in a horizontal direction.
The fabric into which the pile is to be inserted and secured, is placed on a beam,
and conducted over one or more guide bars to the bar having the vertical pins
inserted therein, in front of which is a roller provided with cutting knives attached
to the circumference.
The yarn for the formation of the pile is placed in any suitable position and
conducted to a series of needles, which on being operated in the manner as before
described insert the yarn in the fabric, at the same time the bar with the vertical
pins ascends such a distance as to prevent the inserted yarn being drawn back on
the retreat of the needles, thus by these means forming a loop of each thread of
yarn each time the needles are inserted.
By the rotation of the cutting knives close to the before mentioned vertical pins,
the top of the loops is cut, thereby forming the pile, the fabric being drawn from
the beam by means of a spiked roller or other suitable arrangement, at a speed
proportionate to the number of insertions required in a given length.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Cut Pile Fabrics.
We, JOHN WIMPENNY, of 49 Carlisle Street, Bradford, in the County of York,
Watchmaker, and DIXON REDSHAW, of 228 Priestman Street, Bradford, aforesaid,
Mechanic, 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 has for its object, the construction of a machine by which yarn
may be inserted in and secured to a woven fabric after the said fabric has left
the loom, and to cut the inserted yarn in such a manner that, has the appearance
of pile fabric, such as is woven and cut in a plush loom.

invention,
Fig. 2 is an end view thereof,
Fig. 3 a view of the opposite end of the machine, and
Fig. 4 a transverse section through line
α,
b.
The working parts of the machine are driven by one of the pullies A, motion
being transmitted therefrom to the main shaft B. of the machine by means of spur
wheels C.
The cloth D which is to form the ground or backing of the pile fabric, is placed
upon the beam or roller E. and may be conducted direct between the supporting
bars F to the spiked stripping rollers G as shown by Fig. 4.
The yarn for the pile is by preference placed upon the beam H. and conducted
to the horizontal reciprocating needles secured to the bar J in any convenient
manner.
"
Upon one end of the main shaft B. are secured two tappets K and K', and on
the other end of the said shaft is secured a spur wheel C, on the face of which are
respectively secured the "crank pins A' and A3, which on the rotation of shaft B,
give a reciprocating motion through rods L.. L. to the before mentioned needle
bar J.
The periphery of the tappet K¹ operates the arm M, one end of which is secured
to the shaft N, to which are attached a number of short arms O. for the purpose as
hereinbefore described.
The tappet K operates the lever P. supported on fulcrum pin P³ and the said
lever is connected by a rod Q to another lever mounted loosely on a stud or short
shaft R. To this lever a pawl S is attached, by which an intermittent motion is
given to the ratchet wheel T and pinion T attached thereto, and by the latter
through the spur wheel U to the spiked stripping roller G.
Upon the main shaft B. two or more tappets W are secured, which operate
through the levers X. the needle bar Y. provided with a number of needles corre-
sponding to those in the horizontal reciprocating needle bar J.
The action of the machine is as follows: The cloth D for the backing or ground
of the finished pile fabric, is conducted from the beam or roller E to the spiked
stripping roller G in the manner as before described, and is held in its required
position during the time the horizontal reciprocating needles J' and the vertical
reciprocating needles Y¹ are forming the loops for the pile, by another series of
horizontal needles Z. secured to a bar attached to the short arms O, the said needles
passing through the holes bored in the before mentioned supporting bars F.
The yarn from the beam H passes through the eyes of the series of needles J
attached to, and operated by, the horizontal bar J, the needles pierce the cloth D. and
carry the yarn some distance through the same, by which means, each needle J¹
forms a loop on one side of the ground or backing cloth at each revolution of the
main shaft B, the loops being retained in the manner as hereinbefore described.
Before the retreat of the needles J' the vertical needles Y' and bar are operated
in a vertical direction upwards, such a distance that, the said needles engage in the
loops formed by the insertion of the yarn through the ground or backing cloth,
thereby retaining the loops on the withdrawal of the needles J'.
When the last mentioned needles are clear of the cloth D, the vertical needles Y¹
descend, and the series of horizontal needles Z are withdrawn, clear of the cloth,
thus liberating the same, so that on the operation of the spiked roller G, a certain
length of the cloth D is drawn from the roller E when the operation of forming
the loops is repeated.
The yarn at the ends or tops of the loops are cut by means of a revolving circular
and spirally bent knife T rotated by a belt passing over pullies P¹ and P³, and
mounted on journals attached to the vertical needle bar Y, thus converting the loops
into what is known as pile.

page_text: Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
1. The combination of the horizontal needles J and Z with the vertical
needles Y arranged substantially in the manner and for the purpose as hereinbefore
set forth.
2. The combination of the horizontal needles J' with the vertical needles Y' and
revolving knife T' arranged substantially in the manner and for the purpose as
hereinbefore set forth.
3. The combination of the parts forming the complete apparatus arranged sub-
stantially in the manner and for the purpose as herein before set forth and illustrated
by the accompanying drawings.
