Improvements in the Method of and Apparatus for Winding the
Yarn on to the Spindles of Mules and Twiners and for other like
Purposes.
I, ISAAC CLEGG SCHOFIELD of 3 Park Road Elland, in the County of York,
Cotton Doubler do hereby declare the nature of this invention to be as follows:-
The object of this invention is to dispense with the Clicks, Click wheels and Springs
now (heretofore) used on Mules and Twiners for the purpose of winding the yarn on
to the spindles of the said Mules and Twiners.
For the purpose of carrying out my invention, I employ a peculiarly constructed
Clutch Motion or Apparatus hereinafter described.
(1.) I fix a disc of any form or dimensions on to the tin roller shaft, which said disc
connects or gears-by means of one or more hubs-internally, with a drum or pully
whose inner surface, may be either smooth or indented-The above drum or pully is
not slid along the shaft, but is loose upon the shaft & has a side flange overlapping
the aforementioned disc.
(2.) I employ another pully with a side flange or rim to overlap the aforesaid disc
and hub or hubs, and so prevent the clutch from operating until requisite―The above
pully is slid along the shaft upon prongs on the boss of the aforesaid disc, and revolves
with the shaft and the disc.
(3.) The connection of the Clutch motion may be formed by the locking of the
fallers or by the revolving of the camm shaft.

page_text: I, ISAAC CLEGG SCHOFIELD of 3 Park Road Elland in the County of York Cotton
Doubler 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:
The object of this inventions is to dispense with the clicks, Click wheels, & springs
now (heretofore used on Mules & Twiners, for the purpose of winding the yarn on to
the spindles of the said Mules and Twiners. For the purpose of carrying out my
invention emply a peculiarly constructed Clutch Motion or Apparatus, herein after
described.
(1.) 1 fix a disc of any form or dimensions on to the tin-roller, or operating shaft,
which said disc connects or gears by means of one or more hubs internally with a
drum or pully whose inner surface may be either smooth or indented-which said
drum or pully is loose upon the shaft and has a side flange overlapping the afore
mentioned disc.
(2.) I employ another pulley with a side flange or rim to overlap the aforesaid disc
& so prevent the Clutch from operating till requisite-This second pulley is slid along
the shaft upon prongs on the boss of the aforementioned disc, & revolves with the
shaft & the disc The side flange of the second pulley overlaps the disc & hubs & forms
a kind of cap to prevent the hubs from being thrown off the disc by the Centrifugal
force in the revolution of the shaft-Also this second pulley is in turn overlapped by
the side flange of the first-mentioned drum or pulley whose inner surface may be either
smooth or indented-The two, side-flanged pulleys remain overlapping each other
while the carriage of the mule or Twiner is drawing out-During the drawing-out
process the clutch motion requires to be disconnected or
"out of gear
But when
the
yarn is being wound on to the spindles i.e. during the "taking i in process of the
carriage, the Clutch motion requires to be connected or geared This connection
is formed by withdrawing by a forked-lever-clipping the boss-the inner pulley from
the disc simultaneously with the change or reverse motion of the carriage & thereby
allowing the hubs to fall into the indentation of the outer pulley which thus becomes
scotched or "Wedged by the pulling of the winding chain which is attached to
or connected with it-When the carriage commences" drawing out" the second pulley
referred to, again overlaps the disc & destroys the connection.

In order that my invention may be fully understood I will describe the accompanying
sheets of drawings:-
:-
Fig. 1. A. front view of disc to be fastened on to the tin roller shaft.

page_text: Fig. 3. B. front view of drum or pulley with side-flange, with indentations on
inner surface.
Fig. 4. B section of same.
Fig. 5. C. front view of a second drum or pulley with sideflange or rim to overlap
disc, A.
Fig. 6. C. section of same.
Fig.
D. front view of Hub.
Fig. 8. D. section of Hub.
Fig. 9. A. B. D. shows the Clutch Motion in operation, but without the sideflanged
pulley C.
The Hubs D Figs. 7 & 8. may be constructed of any hard substance as Iron Wood
vucanite or India Rubber-They may be cast or turned in one piece having projections
or spindles on each side as in Fig. 8. which said projections or spindles slide along
the slots in the disc A & thus guide the hubs, (which fall by their own gravity) into
the indentations of the sideflange B just at the point that happens to be the lowest
when the sideflange C is withdrawn from covering the disc A & the hubs D.
The slots in the disc A may be of any suitable curvature so as to form a wedge
clutch in connection with the hubs D and the sideflange B as in Fig. 9.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
1 claim is
-
An internal Wedge Clutch-overlapped by a pulley with a side-flange to prevent the
gearing or scotching of the clutch during the "backing off" process.
