MECHANICAL PARTS FOR TWISTING THE FRINGE.
The mechanism for twisting the fringe consists firstly of two screws, right and
left handed respectively which are made with double threads on part of their length
and single thread on the remainder. The double screw being run into single screw
at the point Figs. 7 and 14.
The head of the double screw g' has a pin g' run through it, to the centre of
which is attached the end of spring. When the screws revolve, the pins rise and fall
because the centre of the end of the spring is placed a little higher than the centre
of the screw, the latter having a slot in the end, which allows the spring to draw
the pins together in the centre as indicated at Fig. 9 which gives the head of the
screw in detail on large scale. The heads of screws 9 are kept in position by neck
ties o Figs. 7 and 8 to which is also fixed the plate k Fig. 7. The other ends of
screws g are kept in position by the angle iron p Fig. 7.
The fringe having been drawn by the chain c to the pins g³ is separated by the
same and dressed into the screw 9 in proper portions as shown in Fig. 14 and is
kept in the grooves by plates h Fig. 8 on the top.
The separated threads are carried along as the screw g revolves to Figs. 7
and 14, here they come in contact with a revolving rubber or belt i and are rolled
or twisted along the plate which has a rough surface like a smooth file and which
is fixed between the screws g level with the bottom of the grooves and can be
raised or lowered by the screw pl from underneath.
The twisting goes on from the point to here the double screw being cut into
the single screw causes two twists, to drop into one groove before leaving the belt i
consequently they get rubbed or twisted by the same, which brings them together
before reaching the reverse twister / Fig. 7.
The twists having got to come in contact with the rubbing pulley which rolls
or twists them on plate m in the opposite direction to belt i, giving them the final
twist.
Afterwards the fabric is drawn off the machine by means of roller n Figs. 1.
2. 3. 5. and drops onto the floor.
The twisting or rubbing belt i Fig. 7 is caused by an endless link chain the
inside connecting links being higher than the outside so as to keep the belt in
position. The said chain is driven by chain wheel at one end, and is carried
on drum at the other shewn at Figs. 5. 7.
The twisting or rubbing pulley is a flanged pulley having india rubber or leather
tyre fitted in between flunges 'Fig. 11 and is placed in between the screws from
underneath, having a plate m on the top similar to plate k.
For driving the screws g they carry pinions p³ Figs. 1. 5. geared together, one of
which is extended and geared with the large wheel p Figs. 1. 2. 3. 5. 6 which in
turn is driven by a pair of bevel wheels p p Fig. 5, wheel p is on a shaft which
extends through the whole length of the machine, and is driven by spur wheels'

Machine for Twisting Fringes on Shawls, Plaids, and the like.
1, WALTER GLEDHILL of Thornton's Wool Mill, St. Petersburg Russia,
Weaving Master, 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 :-
In the weaving of shawls and plaids etc., that have to be provided with a twisted
fringe at the sides a certain amount of reed space is left without warp, and the.
weft is caught up by a few threads put into the reed at the required distance from
the remainder of the warp.
The weft serves for the purpose of being twisted into a fringe at the sides.
And for the other ends a certain amount of warp is drawn in before starting the
next shawl or plaid.
Referring to the drawings accompanying my Provisional Specification,
Figures 11 show a front elevation, Figure 2 an end view and Figures 34 3B
a plan of a machine according to my invention constructed for fringing two sides
of a shawl simultaneously.
Figures 4, 5, 6 and 7 are respectively a part back elevation, longitudinal section,
part plan and a part longitudinal section of the twisting device.
Figure 8 is a transverse section on the line E F Fig. 6.
Figure 9 shews end and side elevations of the front end of the twisting screws.
Figures 10, 11 and 12 are part transverse sections taken respectively on the
lines G. H. J. K, and L M Figure 6,
Figure 13 shews a longitudinal and a transverse section of the chain driving
device.
Figure 14 shews the condition of the material during operation.
Figures 4 to 13 inclusive are drawn to an enlarged scale.
a a are the sides of a shawl before treatment in the machine and bb shews the.
twisting device which is divided into two parts or classes arranged so as to work
in the centre of a a, the one part serving to carry the fabric over the machine at
the requisite speed, the other part giving the required twist to the fringe.
THE MOTION FOR CARRYING THE FABRIC.
In commencing, the fabric is placed on the machine and is caught by spider-
wheels Q, which are fixed at an angle, in order to stretch and straighten the
untwisted fringe. The first two spider wheels are covered with a fork Q for the
purpose of pressing the fabric onto wheel pins thence it is passed onto a second
pair of spider wheels Q where it is picked up by a third pair and passed under a
pair of pulley brushes Q¹ which press the piece onto pins of chains c.

DRIVING..
For driving the screws gg¹ they carry pinions p³ geared together one of which
is extended and geared with the large wheel p which in turn is driven by a pair of
hevel wheels p³ p, wheel p is on a shaft which extends through the whole length of
the machine, and is driven by spur wheel ..
On the left hand side of the machine are two drums, one fast the other
loose. The fast drum has a spur wheel keyed on its boss and driving
wheel the latter drives shaft which gives the motion to the chain wheel +
that drives the india rubber belt i.
On the shaft at the right hand side is a spur wheel 1° geared into wheel 77
which turns the shaft 8 giving motion to chain c.
On shaft is a band pulley n² driving the wooden roller n.
Ou shaft is a spur wheels driving wheel

by means of intermediate
Shaft gives motion to shaft r by a pair of spur wheels and t¹ which shaft
drives the reversing rubber l.
Wooden roller n is used for drawing the piece off the machine and is driven by
pulley n. The fabric is pressed on to the wooden roller n by an iron roller n³
which is kept in position by inclined bars n. The arrows and thick dotted lines
show fabric going through when working.
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. A machine for twisting fringes on shawls and the like wherein the weft for
forming the fringe is carried in a stretched condition over two revolving screw
spindles having respectively a right and a left handed thread, the weft threads being
separated into groups by revolving sliding pins on the screws, so as to be made to
enter the grooves of the latter, where these groups are first twisted together
singly by a travelling rubbing belt operating in combination with a roughened
surface, and are then twisted together in pairs in the contrary direction by a
rubbing pulley operating in combination with the roughened surfaces, substantially
as described.
2. In a machine for twisting fringes operating as described in the first claim,
constructing the two screw spindles with double threads at their front parts and
with a single thread at their rear parts, so that the single groups of twisted threads
after travelling separately along the double screw threads are made to come
together in pairs in the single screw threads, substantially as described.
3. In combination with the two screw spindles g g referred to in the first and
second claims, the use of pins 9 sliding in grooves in the heads of the screws g¹
and acted upon by a spring g' in such manner that when by the rotation of the
screws the end of the pins approach the weft threads they are made to project
upward between the threads so as to divide these into groups, and are then
withdrawn again, substantially as described.
4. In combination with the screw spindles 9, y, the use of the endless rubbing
belt i and roughened surface k, by the combined action of which the groups of
threads situated in the grooves of the screws are twisted together substantially as
described.
5. In combination with the screw spindles 9 g' the use of a rubbing pulley / and
roughened surface m, whereby when two twisted strands are brought together in a
groove of the single threaded part of the screw, they are twisted together in the

page_text: contrary direction to that in which they were previously twisted, substantially as
.described.
6. In a machine for twisting fringes on shawls and the like, the combination of
spider wheels Q, and spiked endless travelling.chains c which carry the fabric
along over slotted plates ee screw spindles gg with single and double threads,
endless rubbing belt i, roughened rubbing surfaces k and m, and rubbing pulley 1,
arranged and operating substantially as and for the purposes set forth.
