Whereas some spinning machines as hitherto constructed have required a large
base for the number of the spindles employed, thereby involving an undue expendi-
ture of power, and also have their means of production diminished by the alternate
movements of the driving drums and are attended with difficulty and some amount
of danger for operatives; and whereas in other machines the retarding drums must
stop during the unwinding of the yarn on the travelling inwards of the carriage:
And whereas in other machines only lower numbers can be spun and only warp
but not weft, and no cops cither large or small can be made, but the yarn is un-
wound on a bobbin requiring to be drawn by the yarn, besides which the spindle
with bobbin and flyer occupies too much space.
Now under this Invention the above defects in spinning machines are obviated
by means of a new mode of construction in which the process of spinning is con-
tinuous, and from which are obtained the following advantages
Cops of any suitable form and size as well as both weft and warp can be spun.
Space can be better utilized by the new arrangement of the spindles. Speed can
be increased owing to the tube of the flyer being short, light, and well set. Some
dangers to which operatives are now liable are diminished, and the apparatus is
so simple and easy in attendance that young persons may work at it without great
fatigue.

The apparatus consists of an arrangement in which the spindles are placed hori-
zontally, the yarn or thread passes through the tube at the end of the flyer along
one of the arms of the flyer to the end of which it is connected as usual,
and is conducted to the spindle. By the revolution of the said tube of
the flyer, the yarn or thread receives motion, and in case of its breaking
there is a stopping disc worked by hand, and a stopping apparatus allows the
attendant to use his hands freely. After finding the broken yarn or thread, he
draws it through the tube of the flyer, and by drawing back the lever of the
stopping apparatus, he puts the said tube again in rotation in order to unite the
yarn or thread.
The winding of the yarn or thread into the form of a cop is effected in the
following manner :-By the revolution of a heart-formed cam is worked a lever, to
which is connected one end of a chain which is led by means of a pulley to the
spindle frame and fixed thereto, thereby imparting to such frame an upward and
downward movement, more or less rapid, and corresponding with the variations of
form in the cam. By this means the point of the cop is formed. The shape is
given to the cop by a template worked by a screw in such a manner that the said
lever is caused to descend by degrees as the cop increases in size.
The spindle is or may be drawn by the yarn or thread, and its course will thus
depend on the diameter of the cop.
Consequently as the yarn or thread is driven by the drum at a constant speed
that of the rotation of the spindle is required to be less when the diameter of the
cop is less that when its diameter is greater.
And this speed is regulated as required by a retarding mechanism.
On the cop attaining a given size, the frame with the tube of the flyer is with-
drawn, so that the cop can be removed after the attendant has partly unwound the
yarn or thread on the spindle underneath the cop. When the partial unwinding is
done, the said frame is replaced and the machine is put in motion, after the tem-
plate has also been restored to its former position by a turn of the said screw.

PROVEMENTS IN APPARATUS FOR SPINNING YARNS OR THREADS."
"IM-
My Invention of "Improvements in Apparatus for Spinning Yarns or Threads "
has reference to the improvements in spinning machines hereinafter described.
Whereas some spinning machines as hitherto constructed have required a large
base for the number of the spindles employed, thereby involving an undue expendi-
ture of power and also have their means of production diminished by the alternate
movements of the driving drums and are attended with difficulty and some amount.
of danger for operatives. And whereas in other machines the retarding drums
must stop during the unwinding of the yarn on the travelling inwards of the
carriage. And whereas in other machines only lower numbers can be spun, and
only warp but not weft, and no cops either large or small can be made, but the
yarn is unwound on a bobbin requiring to be drawn by the yarn, besides which the
spindle with bobbin and flyer occupies too much space.
Now under this Invention the above defects in spinning machines are obviated
by means of a new mode of construction in which the process of spinning is con-
tinuous and from which are obtained the following advantages:—
Cops of any suitable form and size as well as both weft and warp can be spun;
spaces can be better utilized by the new arrangement of the spindles; speed can
be increased owing to the tube of the flyer being short, light, and well set; some
dangers to which operatives are now liable are diminished, and the apparatus is "so
simple and easy in attendance that young persons may work at it without great
fatigue.
The apparatus consists of an arrangement in which the spindles are placed hori-
zontally, the yarn or thread passes through the tube at the end of the flyer along
one of the arms of the flyer, to the end of which it is connected as usual, and is
conducted to the spindle. By the revolution of the said tube of the flyer the yarn
or thread receives motion, and in case of its breaking there is a stopping disc
worked by hand, and a stopping apparatus allows the attendant to use his hands
freely. After finding the broken yarn or thread he draws it through the tube of
the flyer and by drawing back the lever of the stopping apparatus he puts the said
tube again in rotation in order to unite the yarn or thread.
The winding of the yarn or thread into the form of a cop is effected in the
following manner :-By the revolution of a heart formned cam is worked a lever to
which is connected one end of a chain which is led by means of a pulley to the
spindle frame and fixed thereto, thereby imparting to such frame an upward and
downward movement more or less rapid and corresponding with the variations of
form in the cam. By this means the point of the cop is formed. The shape is
given to the cop by a template worked up by a screw in such a manner that the
said lever is caused to descend by degrees as the cop increases in size.
The spindle is or may be drawn by the yarn or thread and its course will thus
depend on the diameter of the cop; consequently, as the yarn or thread is driven
by the drums at a constant speed that of the rotation of the spindle is required to
be less when the diameter of the cop less than when its diameter is greater, and
this speed is regulated as required by a retarding mechanism.
On the cop attaining a given size the frame with the tube of the flyer is with-
drawn so that the cop can be removed after the attendant has partly unwound the
yarn or thread on the spindle underneath the cop. When the partial unwinding is
done the said frame is replaced and the machine is put in motion after the template
has also been restored to its former position by a turn of the said screw.
Having thus stated the nature of the said Invention I will proceed to describe
more particularly in what manner the same is to be performed by the aid of the
accompanying Drawings in which is represented the apparatus above referred to.

page_text: DESCRIPTION OF THE DRAWINGS.
In Sheet I. Fig. 1 is a longitudinal elevation; Fig. 2, a horizontal section of the
apparatus with the cop begun and completed; and Fig. 3 is a face view of a portion
of the apparatus. In Sheet II. is represented the apparatus for forming the cop
and working the spindle frame; Fig. 4 is a plan view; and Fig. 5, a side
elevation.
The yarn or thread k, Fig. 2, passes through the tube of the flyer a (which is put
in rotation by the centrifugal force of the tube a), on one of the arms of the flyer b,
on which it is connected as usual, and it is conducted by the small ring b¹ on the
spindle. By the revolution of the flyer the yarn or thread receives motion, and in
case of its breaking there is a stopping disc a² worked by hand and a stopping
apparatus h allows, the attendant to use his hands freely. The attendant after having
found the broken yarn or thread on the cop draws it through the tube of the flyer,
and by drawing back the lever of the apparatus h he puts the said tube again in
rotation in order to unite the yarn or 'thread.
cam.
The winding of the yarn or thread into the form of a cop on the spindle is
effected in the following manner :-The spindle frame e, with the short and light
spindles is raised and lowered by the mechanism represented in Sheet II. On the
shaft C¹ there is an excentric or cam in the form of a heart, which in revolving causes
the lever a to ascend and descend owing to the peculiar form of such excentric or
A chain d is connected to the said lever and leads by means of a pulley d¹ to
spindle frame e, to which it is fastened and to which it imparts an ascending and
descending movement more or less rapid, corresponding with the different operating
portions of the excentric or cam c. In this manner the point of the cop is made.
The form of the cop is made by means of the template b, which is worked by a
screw e¹ in such a manner that the lever a is caused to descend gradually in pro-
portion as the cop increases in size.
In the apparatus shewn the spindle is drawn by the yarn or thread and its course
thus depends on the diameter of the cop; consequently, as the yarn or thread is
moved forwards by the drums at a constant speed the velocity of rotation of the
spindle in the case of a smaller diameter of the cop ought to be less than in the case
of a larger diameter of the same. In order to regulate this velocity the retarding
mechanism shewn at f is employed.
.
If the cop has attained the size shewn in Fig. 2 the frame with the tube of the
flyer (this not being shewn by the Drawing) is withdrawn so that the cop can be
removed after the attendant has slightly unwound the yarn or thread on the spindle
underneath the cop. After the said partial unwinding of the cop the frame of the
tube of the flyer is placed in position and the machine again set in motion after the
template has also been restored to its former position by a turn of the screw e*.
Having thus described the nature of the said Invention, and in what manner the
same is to be performed, I hereby declare that what I claim as of my Invention
is,-
.
First. The manner of twisting the yarn or thread and winding it on the spindle
in the form of a cop in spinning machines, as herein before described.
And, Secondly. The new and peculiar construction of the apparatus for twisting
the yarn or thread and winding it on the spindle in the form of a cop, as represented
by the Drawings and hereinbefore described.
In witness whereof, I, the said Henry Schoch, have hereunto set my hand
and seal, the Fifteenth day of May, in the year of our Lord One thousand
eight hundred and seventy nine.
