Improvements in Chenille Cutting Machines.
We WILLIAM HENRY SMITH of Mill Street Kidderminster in the County of
Worcester Carpet Manufacturer and THOMAS COOPER of No. 1 Farfield Street,
Kidderminster, aforesaid Machinist do hereby declare the nature of this invention
to be as follows:-
Our invention has reference to machines employed for the cutting up of cloth
made of wool, cotton or other fibrous material commonly known as chenille or fur
used in the manufacture of carpets rugs and other articles.
The object of our invention is to effect a more rapid cutting than that effected
by chenille cutting machines as ordinarily constructed as well as to produce a more
regular chenille or fur.
Our improvements consist essentially of the following construction and arrange-
ment of parts. We provide the chenille cutting machine with a positive and
regular tension motion consisting essentially of a roller covered with card or
filleting. On each end of the spindle of the said roller is a pulley around which
we arrange a metallic brake by which a strain is put on the cloth operated upon.
This strain is regulated by a screw. Below this tensión roller is a guide roller
and also a can roller which said can roller works freely on its spindle. The cloth
passes from the can roller around the guide roller and from thence to the card or
tension roller hereinbefore referred to. Above the said card or tension roller we
place a contracting roller. This contracting roller has two angular or V shaped
grooves cut in it; cach of the said grooves commences at the middle of the roller
and proceeds to the end of the roller, one of the said grooves inclining to the right
and the other to the left. The said roller is placed in such a position that the cloth
passing round it is contracted and made to take its correct position on the cutting
bed of the machine.
We also provide the machine with a clutch action and a stop motion. We drive
the take up roller and closing cylinder by means of worm gearing. By the use of
the said gearing the cloth is prevented from running back when the clutch is
ungeared which it would otherwise do in consequence of the strain put upon it by
the card or tension roller.
The clutch has for its object to enable the attendant to immediately stop the
passing through of the cloth should it be desirable from any cause to do so, without
bringing the knife cylinder to rest at the same time.

Improvements in Chenille Cutting Machines.
We WILLIAM HENRY SMITH, of Mill Street Kidderminster, in the County of
Worcester, Carpet Manufacturer and THOMAS COOPER, of No. 1 Farfield Street
Kidderminster aforesaid, Machinist do hereby declare the nature of our invention
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
Our invention has reference to machines employed for the cutting up of cloth
made of wool cotton or other fibrous material commonly known as chenille or fur
used in the manufacture of carpets, rugs and other articles.

page_text: The object of our invention is to effect a more rapid cutting than that effected

Our improvements consist essentially of the following construction and arrange-
ment of parts. We provide the chenille cutting machine with a positive and

filleting. On one end of the spindle of the said roller is a pulley around which we
arrange a metallic brake by which a strain is put on the cloth operated upon. This
strain is regulated by a screw. Below this tension roller is a guide roller and also
a can roller which said can roller works freely on its spindle. The cloth passes
from the can roller around the guide roller and from thence to the card or tension
roller herein before referred to. Above the said card or tension roller we place a
contracting roller. This contracting roller has two angular or V shaped grooves
cut in it each of the said grooves commences at the middle of the roller and
proceeds to the end of the roller, one of the said grooves inclining to the right
and the other to the left. The said roller is placed in such a position that the cloth
passing round it is contracted and made to take its correct position on the cutting
bed of the machine.
We also provide the machine with a clutch action stop motion. We drive the
take up roller and closing cylinder by means of worm gearing. By the use of
the said gearing the cloth is prevented from running back when the clutch is
ungeared which it would otherwise do in consequence of the strain put upon it by
the card or tension roller.
The clutch has for its object to enable the attendant to immediately stop the
passing through of the cloth should it be desirable from any cause to do so without
bringing the knife cylinder to rest at the same time.
We will now proceed to describe with reference to the accompanying. drawings
the manner in which our invention is to be performed.
Figure 1 represents in front elevation and Figure 2 in side elevation a chenille
cutting machine containing our improvements;
Figures 3, 4, 5 and 6 represent details of the said machine as hereinafter
particularly explained.
The same letters of reference indicate the same parts in the several figures of
the drawings.
a, a are the standards or uprights of the machine and c is the main shaft
provided with the usual fast and loose pulleys b, b2; d is a second shaft at right
angles to the main shaft e, the said second shaft d turning in the bearings d², d², d²
and receiving its motion through the bevil gearing e, f, the bevil wheelf being
fixed on the end of the main shaft c and the bevil wheel e turning loosely on the second
shaft d (see the sectional view Figure 3). The second shaft d drives the principal
moving parts of the machine by the gearing hereinafter described, and the said
shaft d is provided with the clutch action stop motion hereinafter described.
Above and parallel with the driving shaft c is the tension roller g turning in the
brackets g, on the uprights a, a. The said tension roller g is covered with wire
card or perforated tin and upon the end of the shaft of the said roller g, a
pulley is keyed around which pulley is a metallic brake hereinafter described for
putting the required strain upon the cloth passing around the said tension roller.
Above the tension roller g is the ordinary closing roller or cylinder i for closing
the chenille after it is cut. The closing cylinder is of the ordinary kind and
constitutes no part of our invention.
Parallel to and receiving motion from the closing cylinder i is the contracting
roller r constituting part of our invention. By an examination of Figure 1 it will
be seen that the roller consists of a cylinder having two angular or V shaped
grooves or threads cut upon it one of the said grooves inclining to the right and
the other to the left, each thread or groove commencing at the middle of the roller
and proceeding to the end of the roller. It will also be seen that the summits of
the threads of the contracting roller are of the same diameter throughout, but the

bases of the threads diminish in diameter from the middle to the ends of the roller
(see Figure 1). By this construction of roller the cloth passing around it is
contracted and made to take its correct position on the cutting or knife bed t of
the machine; is the knife or cutting cylinder in which the cutting knives ², k
are fixed, the said cutting cylinder being driven from the pulley on the main
The cutting or knife bed t and cutting cylinder k are of the ordinary
kind and constitute no part of our invention. Below and parallel to the driving.
shaft c is the can roller in on which a
of chenille to be cut is placed. The
said can roller n turns freely in the brackets m², m² and above the can roller is a
guide roller n, turning freely in brackets n', n' to guide the cloth from the can
roller to the tension roller g. The chenille or fur from the closing roller i passes
to the take up roller w and from thence to the roller w2 upon which it is wound.
The direction in which the cloth from the can roller m is slowly drawn through
That
the machine to be cut into chenille or fur is indicated by the dotted line a.
is to say, the cloth from the can roller i passes around the guide roll n and from
thence to the card or tension roller g. From the tension roller g the cloth passes
to the contracting roller r whereby it is contracted and made to take its proper
position on the cutting or knife bed t of the machine. After the cloth passing
over the knife bed t has been operated upon by the cutting roller and thereby
converted into chenille or fur in the ordinary way it passes under the roll v, carried
by the bracket 2 to the closing roller i for closing the chenille after it has been
cut. From the closing roller the chenille or fur passes under the take up roller w
and is then wound upon the roll w³.
We will now proceed to describe in detail the gearing by which the machine is
driven as well as the clutch action stop motion and brake.
The closing and contracting rollers and are geared together and driven by.
the chains which passes over the chain or sprocket wheel 2 on the end of the
closing roller and over a chain or sprocket wheels on the end of the contracting
roller r.
The ends of the contracting roller work in the sliding or adjustable
bearings situated in the boxes or brackets r². The bearings are adjusted
so as to separate the two rollers i and r for tightening or slackening the driving
chains by means of the screws worked by the handwheels 7, the said screws 1³
taking into screw boxes in the said adjustable bearings ¹ (see Figure 2).
The closing roller i is driven from the shaft d by the worm d³ gearing with
the worm wheel turning loosely on the stud d. Cast in one piece with the
worm wheel d* is a spur wheel de which gears with the spur wheel d' on the end
of the closing roller (see Figure 2). The extreme end of the shaft d carries a
second worm w which gears with the worm wheel w* on the take up roller w and
drives that roller.
The clutch action stop mechanism of the shaft d consists of the following parts;
is one half of the clutch made in one piece with the loose bevil wheel e on the
shaft d by which bevil wheel the shaft d is driven from the main shaft as herein-
before explained. The combined bevil wheel and half clutch e and e² is kept in
its place against the shoulder on the shaft d by the collar as best seen in
the sectional view Figure 3 of the clutch mechanism; e3 is the sliding clutch
fastened to the shaft d by the feather key e, and the said sliding clutch is thrown
into and taken out of gear with the half clutch e² by the hand lever j turning on
the stud or centre plate 2 (see Figure 2). The handle end of the lever ; works
in the catch plate best seen in the sectional view Figure 6, the said hand lever
being fixed in its position by engaging it on one or other side of the catch or
projection on the plate as seen in the said Figure 6. By throwing the half
clutch into gear with the half clutch e² the closing and contracting rollers i
andr and the take up roller w are set in motion. By reversing the motion of the
half clutch e the last named rollers are brought to rest and the passing of
the cloth through the machine is stopped without bringing the knife cylinder
to rest.
In order that the operator, when the clutch motion is out of gear may let back

page_text: and take up the fur or chenille on the take up roller w in case of the bursting or
rupture of the chenille the end of the shaft d has a hand wheel y keyed to it by
the turning of which and the shaft d the take up roller w may be rotated through
the worm gearing w³, w without communicating motion to the closing and
contracting rollers.
The brake by which the required tension is put upon the card or tension roller g
is represented detached in side elevation in Figure 4 and section in Figure 5 and
combined in the machine in Figure 1, and consists of the following parts: Upon
the end of the shaft of the roller 9 a pulley his keyed around which pulley a
metallic brake strap g works, the inner ends of the brake strap being jointed
together at g, the opposite ends being tightened or slackened on the pulley h by
the screw bolt and hand wheel at q², the screw bolt working in and opening and
closing the jaws q on the brake strap. The brake is prevented from rotating
with the pulley by means of a stud 95 (see Figure 1) passing through an
opening in the jaws 9 of the brake strap. as seen in Figure 4.
Having now particularly described and ascertained the nature of our inven-
tion and the manner in which the same is to be performed we declare that we
claim as our invention of "Improvements in chenille cutting machines" :-
First The combination in the said machines of a contracting roller for
contracting the cloth before it passes over the cutting hed of the machine by
which it is converted into chenille or fur, the said contracting roller being con-
structed arranged and operating substantially as hereinbefore described and
illustrated in the accompanying drawings.
Secondly-The combination in the said machines of the contracting and card
or tension rollers and metallic brake described and illustrated and the conjunction
therewith of the driving gear described and represented for driving the closing
roller and take up roller.
Thirdly- The arrangement or combination of parts for driving the contracting
roller from the closing roller and for adjusting the contracting roller hereinbefore
described and illustrated in the accompanying drawings.
Fourthly The arrangement or combination of parts hereinbefore described
and illustrated in the accompanying drawings constituting a clutch action stop
motion for rapidly arresting the motion of the cloth in case of the accidental
rupture or bursting of the said cloth in the act of cutting and for other purposes.
