I, WILLIAM EDWARD GEDGE, of No. 11, Wellington Street, Strand,
in the County of Middlesex, Patent Agent, do hereby declare the nature
of the said Invention for "A NEW OR IMPROVED APPARATUS OR "TWISTER-
WHISK FOR DRAWING, SPINNING, REELING, ROLLING UP, TWINING OR TWISTING
AND DOUBLING ALL TEXTILES GENERALLY, AND PARTICULARLY FOR DRAWING AND
THROWING EVERY DESCRIPTION AND KIND OF SILK," a communication to me
from abroad by Louis Rocheblave, scnior, of Alais, Gard, France, to be
as follows:-
-
OBJECT OF THE INVENTION.
The twister-whisk, the subject of this Invention, is an apparatus by
means of which and unon which one or several single or compound

page_text: By the rotary motions of one of its two main parts the twister-whisk
can according to the case and by working only upon a centre of motion
that represents one of the two ends of the textile produce the following
effects :-

page_text: 3°. When the textile through lack of suppleness or through the resist-
ance of its single or compound threads neither runs nor slides easily on
the thread holders or drawing plates of the apparatus these thread
holders or drawing plates must be replaced by pulleys or rollers of
triangular section, and should this inconvenience not be thereby obviated
the whisk U can be made to occupy a transversal position in the twister
frame C by introducing in this latter two toothed wheels.
As silk is the finest of all textiles and that which gives the longest
threads and the greatest number of turns of torsion, the special appa-
ratus which is to spin and work it must combine the following con-
ditions:-
I. Be of small size, so as to occupy little space, especially if it is to
work by groups.
II. Be so constructed as to resist the power of one or several thou-
sands of turns. of rotation per minute.
III. Be light and work casily so as to oppose but a small vis incrtia
to thic driving power.
1V. Reel amongst other lengths of thread those of 10, 20, 25, 33,
or 50 centimetres for every turn of torsion or twisting made on the
whisk U.
.
V. Twist and double in every direction and at every possible degree
one or several threads.
VI. Draw, reel, spin, and roll upon the whisk Ụ one or several
threads.
VII. Combine simultaneously all these effects, and at every degree
upon one or several threads on whisk U, cither by taking the burrs of the
cocoons at the basin or by taking some smooth silk threads on whisks,
spools, or otherwise.
DESCRIPTION OF THE TWISTER-WHISK.

page_text: 5ly. The toothed wheel M fixed on the shaft L.
6ly. The pinion Q fixed on the shaft O to direct the toothed wheel M
actively or passively.
The 5 first pieces of the come and go are dependent on the twister,
and the 6th one is dependent upon the whisk.
The alternate obliquity of the laying of the throad on the whisk U is
regulated by the number of teeth of the pinion Q and of the toothed
wheel M, and by the addition to these two pieces, if required, of two
supplementary toothed wheels supplied with the number of teeth which,
according to the diameter of the whisk U and the breadth of the skein,
will give the best regulation.
The small board H of the come and go arrangement may be replaced
by a flier having its axis of rotation on one of the inner sides of the
twister frame C one of its ends being joined to the connecting rod I,
and the other end supplied with the drawing plate or thread holders
guiding the thread.
The breadth of the skeins of thread which form themselves on the
whisk U depends on the length of the stroke of the crank pin K, and
if the small board H is replaced by a flier the breadth of the skeins
depends doubly on the stroke of the crank pin K, and on the length
of the flier from the point of its rotary axle to one or the other of its
extremities.
The motor is not represented in the Drawing because it does not form
an integral part of the apparatus, and because it may be constructed in
different ways.
However, whether the diameter of the pulleys P and N of the
annaratus is equal or unequal, their circumference convex. -with

page_text: triangular or concave, profile or section, and whether they are or are
not replaced by toothed wheels, the arrangement of the motor must be
able, according to the case, to transmit to them, separately or together
and by means of belting or toothed wheels, one or several motions. of
equal or unequal speed and in the same or contrary direction; then the
motor must be furnished with two pulleys one of which must be an
expansion pulley, that is to say, with its circumference cut in equal
arcs to increase or diminish its radius by small degrees.
When groups of apparatus are to be worked by the same motor and
not by means of toothed wheels, the use of leather straps or belts being
preferable to that of ropes or cords, the circumference of the pulleys
of the apparatus and that of the pulleys of the motor should be slightly
convex instead of being concave or with a triangular section or profile.
The working of the twister-whisk. consists in the turns of torsion or
twisting which its two main parts execute on themselves by the impul-
sion of a single or double motion of equal or unequal speed and in the
same or inverse direction transmitted to them by the motor.
The whisk which rolls or winds the textile and the twister that twists
it are two parts closely bound together, since the stop F, forming a part
of the twister, supports the shaft V, which is a part of the whisk, and 2
that the shaft O forming a part of the whisk serves as axle to the pulley
N, which forms a part of the twister.

.
of the other as to the
Nevertheless, the whisk and the twister, as
apparatus, are entirely independent the one
various rotatory motions they may respectively undergo.
The turns of rotation executed by the twister and the whisk are
individual or collective.
The individual turns of rotation and the collective ones of the whisk
and of the twister give six different combinations, which are,-
2
I. Individual turns of rotation of the whisk from left to right, or from 3
right to left, the twister being at rest.
II. Collective turns of rotation, executed by unequal speed, and in a
contrary direction.
III. Collective turns of rotation, exccuted by equal speed and in a
contrary direction.

page_text: IV. Individual turns of rotation, executed by the twister from left to
right or from right to left, the whisk being at rest.
V. Collective turns of rotation executed by unequal speed and in the
same direction.
VI. Collective turns of rotation executed by an equal speed and in
the same direction.
The come and go mechanism is the auxiliary part of the whisk, and
as such the small board H, participates in all the individual or collective
motions of the whisk and of the twister, and the number of motions
that it undergoes does not therefore cease to be in proportion to the
number of recling and rolling turns of the textile on the whisk U.
