Improvements in or connected with Chenille Machines.
I, WALTER SMITH, of Abbott's Factory, Forest Street, Hyson Green, in the
Town and County of the Town of Nottingham, Chenille-machine Builder, do
hereby declare the nature of this invention to be as follows :-
My invention relates to improvements in or connected with chenille machines
whereby the chenille instead of being made in short lengths, as formerly, can now
be made of any desired length; and instead of the chenille being made in lengths
determined by a traveller, moving down the shop or factory, as heretofore, and
afterwards wound up, my improved machine makes the chenille without the use
of a traveller and winds it upon bobbins, or the like, as fast as it is made.
According to my invention the warp threads are drawn from the bobbins by a
grooved roller, preferably of wood, placed at the back of the head of the chenille
machine in the place of the usual plain roller. Above this grooved roller are
arranged in a suitable manner, say, 4 small rollers preferably of metal, and 2 extra
sleys.
The finished chenille is led to a twister or winding frame carrying a number of
horizontal winding spindles. These spindles carry the bobbins on which the finished
chenille is wound and which are caused to move, at a different speed to the spindles,
by means of a friction brake or tension device acting upon each bobbin. The
bobbins are caused to traverse during their rotation by means of a frame which
carries the friction brakes, and said frame receives a reciprocating motion by means
of two heart shaped cams, operated by suitable gearing, from the driving shaft.
The chenille spindles and bobbins are arranged in tiers and are preferably driven
in the following manner :-A bevil wheel is fixed to the driving shaft and gears
with a pinion fixed on a longitudinal shaft which carries at the other end a series
of sprocket or grooved wheels or pulleys upon which are the belts or chains which
drive the spindles of the lowest tier. The second tier is driven from the first, and
so on. The cams are driven by a worm or bevil wheel on the said longitudinal
shaft which drives a vertical shaft connected by worm or bevil gearing with the
cam shaft.

Improvements in or connected with Chenille Machines.
I, WALTER SMITH, of Abbott's Factory, Forest Street, Hyson Green, in the
Town and County of the Town of Nottingham, Chenille Machine Builder, 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, reference being had to the accompanying drawings and to the
letters and figures marked thereon, that is to say :-
My invention relates to improvements in or connected with those chenille
machines which deliver finished chenille from cutters or chenille rollers, whereby
the chenille, instead of being made in short lengths, as formerly, can now be made

page_text: of any desired length, and can be wound upon bobbins, or the like, as fast as it is
made, the use of a traveller moving up and down the shop or factory being
dispensed with.
According to my invention the warp threads are drawn from the warp bobbins
of the chenille machine by a grooved roller, preferably of wood, placed at the back
of the chenille machine-head in the place of the usual plain roller. Above this
grooved roller are arranged two extra sleys and four small rollers, preferably of
metal. The finished chenille is led to a twister or winding frame carrying a number
of horizontal winding spindles. These spindles carry the bobbins on which the
finished chenille is wound and which are caused to move at a different speed to the
spindles by means of a friction brake, or tension device, acting on each bobbin.
The bobbins are caused to traverse during their rotation by means of a frame
which carries the friction brakes, said frame being reciprocated by means of heart-
shaped cams, or their equivalent, arranged at each side of the winding frame or
twister and operated by suitable gearing from the driving shaft of the chenille
machine. The chenille spindles and bobbins are arranged in tiers, and driven by
chains and sprocket wheels, or by belts and pulleys, by means of suitable gearing
from the driving shaft of the chenille machine.
And in order that my invention may be readily understood, I will describe the
same fully with reference to the accompanying drawings, in which :-
Fig. 1 is a diagrammatic view showing the position of the additional rollers and
sleys, in the chenille machine, with relation to the grooved roller.
Fig. 2 is a plan of the additional rollers at one side of the chenille machine
head, those at the other side being similarly arranged.
Fig. 3 is an elevation of part of the back of the chenille machine head.
Fig. 4 is a part section, to a larger scale, showing the conformation of the grooves
in the grooved roller.
Fig. 5 is a side elevation and Fig. a back elevation of the twister or winding
frame, the cam gearing at the right hand side being removed.
Fig. 7 is a front view, to a larger scale, of one of the chenille bobbins and friction
brake.
Fig. 8 shows the position of the longitudinal shaft with relation to the gear of
the chenille machine.
a represents one of the warp bobbins which are arranged upon the bobbin-board
or table 6 of the chenille machine. The warp d passes from these bobbins through
the sley c in the usual manner, and is led round the grooved roller e.
From this a
portion of the warp threads pass through the usual sley f (Fig. 3) and other portions
through the additional sleys g, y', and over the additional rollers h, h¹, which are
preferably fixed upon the bar which carries the sley f. The additional rollers j, j,
at each side of the head, are also affixed to this bar and are provided to guide the
selvage or waste chenille d'. The warp passes from the additional sleys g, gl, over
the rollers k, l, and to the chenille rollers or cutters m and is formed into chenille
in the usual well known manner. The cutter bearing or head n is preferably formed
with the side n' removable, and with a projection o cast upon the front to carry the
sley and roller bearing p. By this means the cutters can be taken out and put in
again without cutting down the warp threads. The usual arrangement may, however,
be employed.
The finished chenille is led from the chenille machine to the twister or winding
frame (Figs. 5 and 6) which consists of a number of spindles q, q, carrying
bobbins r, r, and rotated by a system of pulleys and chains or belts, as hereinafter
described.
The twister or winding frame is formed of two end or side frames s, s, connected
by bars s,, at the front and back of the frame. At the upper part of the frame
are bolted the horizontal battens or bars s2, s2, of which there are three at the back
and three at front, in a three-tier machine. These bars s', s, carry the spindles 9, 9.
At each side of the frame is bolted a bracket t which carries the bearings t', t, of
the slotted bar u, and a bearing for the cam shaft w.
Cam rollers a, a, are

page_text: secured to the slotted bar u, by means of studs and nuts, said studs passing through
the slot; and the slots in the bars enable the position of the rollers x, x, to be
adjusted so that the proper motion may be given to the brake frame by the
cams y, y.
The brake frame is bolted to the bars u, of which there is one at each
side of the winding frame, and said brake frame consists of two vertical end bars y²,
and three horizontal bars, 2. On the horizontal bars, z, are arranged the brake
blocks or friction pieces A, upon pins B. The amount of friction or pressure is
regulated by means of weights B (Fig. 7) hung at the end of the brake blocks.
The blocks A lie in channels C, C, formed in the end discs of the bobbins r, r.
The length of the bobbins r is equal to the throw of the heart-shaped cams y, so
that the traverse motion given to them, during their rotation, by the heart-shaped
cams shall wind on the chenille uniformly in layers. At the bobbin end of the
spindles 9, 9, are fixed the rotating arms or flyers D. The finished chenille E
enters the twister by the aperture F, passes through the hole F', thence through
the rings F2 and F3 on the flyers I) to the bobbin r. In the winding frame shown
on the drawings there are 24 spindles and bobbins, each of the construction repre-
sented in Figs. 5 and 7, but it is evident that the number of bobbins, the number of
tiers of spindles, and the construction of the brakes may be varied without departing
from the nature of my invention. The spindles g, g, have pulleys or sprocket
wheels G, G, G, G', keyed to them, and chains or belts connecting the wheels of
one tier with those of the next tier.
In a three-tier machine, as represented on the drawings, the pulleys or sprocket
wheels G, G, of the top tier of spindles are arranged at the back of the twister and
are connected by belts or chains with the pulleys or sprocket wheels G¹, G¹, on the
spindles of the second tier. On the spindles of this second tier are keyed the
pulleys or sprocket wheels G, G, at the front of the machine and these are
similarly connected with the pulleys or sprocket wheels G³, G³, on the lower
or bottom tier of spindles. Pulleys or sprocket wheels H, H, H, are keyed to the
lower spindles at different distances from their bearings, in such positions that said
pulleys or sprocket wheels may be conveniently connected by belts or chains 1, 2, 3,
etc. with the compound wheel or series of pulleys or chain wheels J, J, J, which is
fixed to the longitudinal shaft K. The pulleys or sprocket wheels H are, with the
exception of the first, which is keyed on the end spindle of the second tier, fixed
upon the spindles of the bottom tier. The longitudinal shaft K is suitably supported
by bearings and carries a worm L which gears with a worm wheel M keyed to the
vertical shaft N. The other end of the shaft K receives motion from the ordinary
driving shaft P of the chenille machine, preferably by means of bevil or mitre
wheels Q, Q. The vertical shaft N carries a worm R at its upper end, which gears
with a worm wheel S keyed to the cam shaft w, and by means of which the cams
are operated.
The bevil wheel by which the shaft K, with wheels J and worm L, is operated
from the driving shaft P of the chenille machine, is keyed to said shaft P at the
opposite end to the usual gearing which drives the chenille machine head gear T
and U, and the grooved roller e (Fig. 8). By actuating all the parts of the
twister or winding frame from the same driving shaft as the chenille machine,
as herein described, the winding of the chenille is more uniform than if the twister
be driven from separate shafting.
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
claim is :-
1. The improved chenille machine, having grooved warp roller, four extra rollers,
and two extra sleys above said roller, and working in combination with a winding
frame, actuated from the same driving shaft, substantially as herein before described
and shown on the annexed drawings.
2. The combination with a chenille machine, of a twister or winding frame having
horizontal spindles and bobbins wherein the bobbins receive a traverse motion as

page_text: well as a rotatory motion for the purpose of winding on any length of chenille
in layers, as herein before described.
3. In a chenille machine, the use of the grooved roller e to receive the warp
threads from the warp bobbins, as shown and described.
4. In a chenille machine, the employment of four extra rollers and two extra 5
sleys to receive the warp from the warp roller, as herein described.
5. The twister or winding frame for winding finished chenille upon bobbins or
the like, having its parts arranged and combined to operate substantially as
herein before described and as shown in the drawings.
6. My improvements in or connected with chenille machines whereby the use of 1
a traveller is dispensed with and the chenille can be made of any desired length
and be wound upon bobbins or the like as fast as it is made, substantially as
hereinhefore described.
