A Machine for Cutting Chenille Cloth
the City of
We, WILLIAM TALBOT, residing at 116 Sherbourne Street, in
Toronto in the County of York ind Province of Ontario, Carpet Manufacturer,
and JAMES PFTER MURRAY, residing on Castletrink Avenue, in the sud City of
Toronto President of The Toronto Carpet Manufacturing Company, Limited,
do hereby declare the nature of this aid invention and in what manner the same is to
be performed to be particularly described and ascert uned in and by the following
statement
-
In the manufacture of chenille goods the chenille is first woven into what is
technically known as chenille cloth with the warp threads equi-distant from each
It has always
other and at regular intervals and parallel to the sides of the cloth
been impossible heretofore to get a machine which will evenly cut the weft threads
or filling between the warp threads into the chenille strips all uniform and even
throughout their length, and the object of this invention is to produce a machine
which will evenly cut the weft threads or filling of the chenille intermediate and
parallel to the warp threads with rapidity and precision, and to so arrange the
machine that in the event of any irregularity the cloth can be thrown away from
the cutters without the necessity of stopping the machine, and the invention
consists essentially of a machine having a bed plate provided with a series of
grooves arranged equi-distant from and parallel to each other, corresponding in
number and location with the number and location of the warp threads, a series of
slots intermediate the said grooves, a series of cutter knives loosely journalled on
and revolving with a shaft engaging with the slots formed in the said bed plate
intermediate the grooves for the warp threads, and means for moving the bed plute
to and from the cutter knives the whole device being hereinafter more fully set
forth and more particularly pointed out in the claims

The machine consists of a stand or frame A Formed in the middle of the top a
of the frame A are bearing boxe- B, in which re journalled the ends of the shaft C
The shaft is provided with a longitudinal pline D Mounted on the shaft C
contiguous to the inner ends of each of the journals E are collars or washers F
spline D extends from the collars or washers F contiguous to one of the journals E
to the collars or washers F contiguous to the other journal E Mounted on one end
of the shaft ( IS a fist pulley G Mounted and longitudinally movcable on the
shaft are a series of cutting di es H Each of the cutting dises H is provided
with bore I through which passe the shaft C, and each of the di cs H is provided
with recess or enlargement in continuation of the bore I into which fits the 1
spline D to cause the cutting discs to revolve with the shaft ( The cutting
discs He held separated from each other by series of washers J mounted on
the shaft (between the said cutting dise The cutting discs and washers are
free to move longitudinally on the shaft in order that they may have sufficient
play to overcome the vibration of the machine, o that at all times they may cut
the chenille cloth evenly between the warp threads Bolted to the top of the
frame A on the front side of and contiguous to the cutting discs His guide bar K
provided with series of slots arranged equi-dist int from each other, and at
regulu intervals, and corresponding in number und location with the number and
location of the cutting discs H Mounted in the top of the framework A below
and in front of the cutting discs H is rock shaft L, to one end of which is
connected lever M having a spring dog engaging with the notches 0 of 1
segment P, secured to the top of the frame adjacent to the sad lover M
connected to each end of the rock shaft L1 in arm R which worl in
in the under side of the bed plite I The ends of the bel plate I work in
guides U formed on the top a of the frame ind in front of the cutting discs H
That side of the bed plate T contiguous to the cutting disc. H is provided with a
series of literal grooves V extending to the cutting edge to receive the warp
threads of the chenille cloth and is provided also with series of slots Winter
mediate the grooves V, in each of which works one of the cutting discs H
The
number and location of the slots W correspond with the number and location of the
cutting discs, and the cutting discs working in the slots W of the bed plate and
the slots of the guide bar K are held in their proper relation to the chenille
cloth whilst it is pissing over the bed plate and being cut into chenille strips
warp threds of the chenille cloth are held in the grooves V which are located
intermediate the slots W, and the tension of the chenille cloth whilst it is passing
over the bed plate is sufficient to permit the grooves V to hrmly hold the warp
threads therein Journalked in the front of the frame A midway between the top
and base is the unwinding roll X, one end of which is Jounalled in
brake Y to permit of the requisite to ision being placed on the chenille cloth
Journalled at the rear of the frame A is a winding roll 4 suitably driven preferably
by a gering operated from the main diving shaft c The main driving shaft c
15 journal'ed in the frime vertically below the shaft C, and mounted on the main
driving shaft c 14 a fist pulley d Passing around the pulleys d and G is a duive
belt e by means of which motion is transmitted from the main driving shafte to the
shaft for the cutting dises Mounted on the end of the main driving shaft con
the outer side of the fast pulley d are a set of pulleys f, by means of which motion
is transmitted to the machine In the operation of the machine the chenille cloth
is placed on the unwinding roll X and passed over the bed plate T, the warp
threads of the chenille cloth are placed in their re pective grooves V, and con-
nected with the winding roll Z, The bed plate is then moved to the cutting
discs H by means of the rock shift L and arin R operated by the lever N
T'he
machine is then set in motion, and the revolution of the cutting discs cuts the
chenille cloth evenly into chenille strips, and the revolution of the winding roll, Z,
draws the chenille cloth across the bed plate T The bed plate T holds the
chenille cloth against the cutting discs H In the event of any of the warp
threads being displaced from their respective grooves V the lever M can be moved
The
friction

page_text: in the direction indicated by the arrow, and the chenille cloth moved away from
the cutting disc The bed plate T being supported upon the ends of the arms R
follows the arc of movement described by aid arms when turned and thus the
tension on the bed plate T of the chenille cloth will always be the same whether
the bed plate is close to the cutting discs or away from the same
Having now particularly described and certained the nature of our said inven-
tion, we hereby declare that we are aware of the Specification of Howard Lees
