This invention relates to apparatus employed in self-acting mules known as the
winding-on inotion, and consists in a mode of actuating the quadiant screw, whereby
the tension of the yain may be automatically governed or regulated during the
operation of building the cop
According to my invention I employ an endless band or belt placed below the
mule cannage, which passes over a grooved pulley working on a stud fixed neai
the back of the headstock, and over a second pulley arranged in conjunction with
the bevel wheels which actuate the quadiant sciew, to operate in such a manner as
that when the endless band or belt is moved in one duection the sciew will be
rotated, but if moved in the opposite direction the pulley will be moved round
upon its axis or shaft without actuating the screw.
The latter effect may be pro-
duced by means of a ratchet-and-pawl arrangement, or other similar device
The upper line of the endless band or belt passes between the upper side of a
projection or bracket fastened to the lower portion of the carriage end and the
lower side of the extremity of a lever, whose opposite extremity works upon a pin
or axis supported in a bracket also attached to the carriage That end of the lever
which is over the projection is suspended from an aim fastened to the counter-
faller, and is so adjusted that should the yain during the operation of winding-on
become too tight, causing the counterfallei to be thereby depressed, the lever will
in consequence be lowered, so that the endless band or belt which passes below
will be held or gupped between it and the projection, and will be pulled or drawn
as the carriage recedes, so as to actuate the quadiant screw and alter the position
of the winding-on chain, thereby bringing the yain to the tension required.

page_text: Means for adjusting the position of the lever, the tension of the endless band or
belt, as also an arrangonent for increasing its hold or friction on the pulley, which
actuates the quadrant screw, are provided.

"IM-
This Invention relates to apparatus employed in self-acting mules known as the
winding-on motion, and consists in a mode of actuating the quadiant screw, whereby
the tension of the yarn may be automatically governed or regulated during the
operation of building the cop
The nature of my Invention, and the manner of carrying it into practical effect,
will be readily understood from the following descuption thereof, reference being
had to the accompanying Sheet of Diawings, in which,-
Fig 11s a side elevation of so much of a spinning mule as is necessary to illustrate
my said Invention
Figs 2 and 3 are respectively a sectional view and an end view shewing details
of inechanism in connection with the lower end of the quadiant screw, and Figs 4
and 5 are respectively a side view and an end view of that portion of the apparatus
which in practice is attached to the mule carriage, but is in these views shewn
detached so as to be more readily understood.
In the various Figures the sume letters of reference are used to denote corre-
sponding parts
A (Fig 1) represents the framing of an ordinary mule headstock, B, the aim of
the quadiant enclosing the quadiant screw C, the mule cannage, and G, the
winding-on chain, Diepresents the endless band or belt passing over a grooved
pulley E. This pulley is supported on a stand F is a second pulley which
iotates on the axis 01 shaft e, and is arranged to operate in conjunction with bevel
wheels a and a¹ (see Fig 2) which actuate the quadiant screw, b, c, (Figs 2 and 3)
is a catch wheel having teeth or notches d, d, d The catch wheel c and the bevel
wheel a arc fastened on a common boss or centre, they and the pulley 7 are free to
rotate on the shaft e, f is a pawl supported on a plate or disc h, which forms the
back of the pulley g, 2 18 a spring clasping the boss on which the wheels c and a
are fastened The arrangement of the catch wheel c and sping 2, as shewn, is such
that when the pulley g is 1otated in one direction (2e, in the direction indicated
by the arrows in Figs 1 and 3) the pawlf will bear against one or other of the
teeth d, d, d, but when rotated in the opposite duection the position of the pawl
will be so altered as to allow it to be carried round with the pulley g without
touching any of the teeth on the catch wheel c I is a projection or bracket
attached to the mule carriage C, over which the endless belt or band D passes
within a V shaped groove, the projection or bracket II being constructed in three
pieces or portions 3, 4, and bolted together in the manner shewn in Figs 4 and 5,
thus providing means for adjusting the portion 7 vertically and horizontally as
requied, is a lever or bar jointed at one end to a bracket 7, and suspended at
the other end by a chain m (Fig 1) passing beneath the friction bowl n
extremity of this chain is fastened to the counter faller o, and the other to one end
of a bell-crank lever p (Fig 1) supported on the extremity of a bracket 9 on the
faller rod + The other end of the lever p is jointed to one end of a connecting or
radius rod 8, whose other end 18 jointed to a slotted bracket y. The compounding
of the lever p and radius rod s with the bracket q is designed to give the lever ka
quicker and more extended up-and-down movement than would obtain if operated
The onc

page_text: directly by the faller u That end of the lever or bat k near the front of the car-
riage C is provided with a vertical arm to which is attached at night angles a grip-
ping piece or knifo t (see Fig 5)
The action of the apparatus is as follows -During the operation of winding-on,
or when the mule carriage is receding from the quadrant, the faller u and the lever k
will be in the position shewn in Fig 1, but during the operation of spinning, or
whilst the carriage is approaching the quadrant, the faller will be raised, thereby
bringing the level to the position indicated by dotted lines If during the
building of the cop the yain should become too tight the counterfaller o will be
so fai depressed as to lower the lever . sufficiently to cause the endless band or
belt D to be held or gripped between the gripping piece or knife tand that portion
of the bracket 1 maikud 3, and as the carnage recedes the band or belt D will be
pulled or diawn so as to iotate the pulley g Instead of the pulley g being caused
to actuate the quadrant screw during the receding of the carriage, as mentioned in
my Provisional Specification, I prefer to modify this arrangement by causing the
quadiant screw to be actuated during the outward stretch of the canlage, and to
this end I reverse the position of the catch wheel and pawl, thereby relieving the
lever and gupping knife t, which by this arrangement are only required to give
motion to the band or belt itself Upon the endless band I fasten a boss or disc w
(see Fig 1) If the disc be moved along with the band during the winding-on, the
return movement of the camage will cause the lips x, x, on the bracket to come
in contact with the boss or disc w, and push it back to its former position, at the
same time actuating the catch wheel and quadiant screw, thereby altering the posi-
tion of the winding-on chain, and bringing the yarn to the tension requned.
Having now described the nature of my said Invention, and the manner of car-
ying it into practical effect, I would have it understood that I do not claim generally
either the use of an endless travelling band or belt arranged to be checked by the
depression of the counter faller, or the actuating the checking apparatus by means
of the counter faller, noi lo I lay claim to any of the mechanical parts herem-before
shewn and described when taken sepuately and apart from the combination or
application thereof in manner and for the purposes herein-before described and
shewn, but what I consider to be novel and original and therefore clann as secured
to me by the heiein-before in part recited Letters Patent is, the combination of
parts constituting the improved apparatus constructed, arranged, and operating as
herein-before described and shewn in my Diawings for automatically actuating the
quadiant sciew, as and for the purpose specified
In witness whereof, I, the said Joseph Ormerod, have hereunto set my hand
and soal, this Tenth day of July, in the year of our Loid One thousand
eight hundred and seventy-seven.
