page_text: Improvements in Spinning Mules.
I, JAMES KELSALL, of West Grove, Chorlton-on-Medlock, Manchester, in the
County of Lancaster, Foreman Fitter, do hereby declare the nature of this inven⚫
tion to be as follows:-
This invention relates more particularly to woollen mules though it may also
be applied to mules for spinning cotton or other fibres and it is designed to provide
an extra speed motion for driving the spindles.
Upon the tin roller shaft is placed a grooved tin roller pulley mounted upon a
brass bush or otherwise free to rotate on the shaft but without lateral movement.
Attached to or forming part of the grooved pulley is an internal friction cone
(or clutch box) capable of freely rotating on the shaft with the grooved pulley.
On the same shaft I also mount loosely to rotate thereon a toothed wheel or
pinion attached to one half of a clutch box. Between the grooved pulley and its
friction cone and the toothed wheel and its clutch box or friction clutch I mount
on the tin roller shaft on feather keys a sliding piece carrying at one end a fric-
tion cone to engage the internal cone and at the other end half of a clutch box
or friction clutch to engage the clutch. These rotate with the tin roller shaft
but are capable of lateral movement so as to be placed in gear with either the
friction cone on the one side or the clutch box on the other and thus take motion
from the grooved rim pulley or the toothed wheel. The grooved pulley and the
toothed wheel are rotated at different speeds and thus impart a higher or lower
speed to the tin roller shaft as desired. The toothed gear may be either helical
or skew gear bevel gear or may be substituted by any other suitable gear.
Instead of friction or other clutches a ratchet wheel and pawl may be arranged
to transmit motion to the tin roller shaft.
On a second shaft preferably parallel to the tin roller shaft is placed a grooved
pulley driven by the same band as the tin roller pulley from the rim pulley or
direct from the same rim pulley or a second rim pulley or in other suitable
manner. This shaft is provided with gears either worm helical skew bevel or
otherwise according to the speed required, to transmit motion to the toothed or
other gear on the tin roller shaft and a cross shaft at right angles to these two
shafts carries corresponding wheels to gear with the wheels thereon. The gear
will be varied or adapted to correspond with the speed to be transmitted there-
through whether less or greater than that transmitted direct through tin roller
pulley. I at present prefer to transmit the fast speed through the tin roller
pulley and the slow speed through the second shaft and gear wheels but this
may be reversed.

page_text: The gear between the second shaft and that at right angles thereto will serve
as change wheels which can be easily removed and replaced.
Instead of a third shaft at right angles to the counter shaft and the gearing
thereon the counter shaft may be fitted with a pulley with one two or more
grooves and a corresponding pulley be placed on the tin roller shaft in connec-
tion with the clutch box and the motion be transmitted from one shaft to the
clutch on the other by a rope or band.
The sliding piece carrying the two clutches is fitted with a depending lever
by which it is moved to one side or the other to bring either of the clutches
into gear.
✓-
The operating lever is moved in one direction by a spring and in the opposite
direction by a slide or incline attached to the floor past which the carriage runs
or the spring may be dispensed with a double slide or two slides may be
employed to move it first in one direction and then in the reverse as required.
To act as a spindle stopper the slide is arranged to hold both clutches out of
gear or engagement at the same time.
Two different speeds are thus obtainable for the tin rollers and spindles and a
third speed can be obtained in the usual way by a counter shaft driving on to the
rim shaft in addition to being completely stopped during a portion of the run of
the carriage.

page_text: pulley. On the tin roller shaft B I also mount loosely to rotate thereon a helical
pinion F to which is attached on half f of a clutch box,
Between the grooved pulley D and it friction cone E and the wheel F and its
clutch I mount upon the tin roller shaft B on feather keys
a sliding sleeve
or piece G carrying at one end a friction cone E¹ to engage with the internal
cone E of the pulley D and at the other end a half clutch fl to engage the
clutch of the pinion F. The sleeve G and the friction cone E and the clutch f
rotate with the tin roller shaft B and have a lateral movement thereon.
The sleeve G is capable of being moved to and fro on the tin roller shaft B
by a forked lever H so as to place the friction cone E in gear or engagement
with the internal cone E of the grooved pulley 1) or the half clutch fin gear
with the half clutch f and thus take motion from either to drive the tin roller
shaft and tin rollers.
The grooved pulley D and friction cone E are driven at different speeds to the
pinion and clutch thus the speed of the tin roller shaft B is varied according
to the position of the sleeve G, a higher or lower speed being imparted to it as
desired. The sleeve G may also be placed in a central position so that neither
part may be in gear and then impart no motion to the tin roller shaft and thus
stop it.
The friction cones E and E¹ may be replaced by a clutch box and the
clutches ff may be replaced by friction cones but I prefer the arrangement
shown.
The helical pinion F is driven by a helical pinion F but these may be sub-
stituted by skew bevel or any other suitable gearing.
I place a second shaft K parallel to the tin roller shaft B and to this I affix
a grooved pulley L driven by the band M by which the grooved pulley D on the
tin roller shaft B is driven from the rim pulley (not shown). The second or
counter shaft K is geared by helical pinions k¹ or by skew gearing or otherwise
with a transverse shaft K' to which the gear wheel F is affixed and by which
motion is transmitted to the sleeve G when the clutches ff are in gear.
The grooved pulley L is preferably smaller than the grooved pulley D and the
shaft K is preferably driven at a greater speed than the pulley D but the
shaft K can be driven at a greater or lesser speed than the pulley D by a larger
pulley on shaft K or by suitable arrangement of gearing. The gear can be
adapted so as to use the extra speed for slow motion or intermediate motion
according to requirements and if at any time the extra speed should not be
required, the motion can be put out of gear and the mule can be worked as an
ordinary mule with or without the use of the slide P' as a spindle stopper.
The second grooved pulley L instead of being driven by the band M which
drives the grooved pulley D may be driven direct from the same rim pulley or
from a second rim pulley or in a suitable manner from any other source of
motion. N is a guide pulley rotating on a stud n to guide or direct the band M.
The gear between the second shaft K and the shaft K' at right angles thereto
will serve as change wheels which can be easily removed and replaced.
In the modification shown in Figs. 5 and 6 I arrange the friction cones EE
only upon the tin roller shaft B and the clutches ff upon the cross shaft K¹
the gear wheel F being keyed to the tin roller shaft B and the wheel F" loose
upon the transverse shaft K and connected to the loose part of the clutch the
other or sliding part of the clutch sliding on feather keys in the shaft K'. In
this arrangement the friction cone E is keyed to the tin roller shaft B and the
friction cone E and grooved pulley Dare loose thereon and operated by the lever Gi
and the clutch f¹ is operated simultaneously by a lever G2 and a bell crank
lever g with a forked end at g² which engages with lever G³. The spring O is
attached direct to the lever G¹.
The lower end g of the lever G₁ is pivoted to move out of action on the inward
run or traverse of the mule carriage and thus avoids giving any shock.

page_text: Instead of the shaft K' at right angles to the tin roller shaft B and the counter
shaft K and the gearing thereon the counter shaft K may be fitted with a pulley
with one two or more grooves and a corresponding pulley be placed on the tin
roller shaft in connection with the clutch box and the motion be transmitted
from the shaft K to the clutch on the tin roller shaft B by a rope or band.
The forked operating lever G is moved in one direction by a spring O and in
the opposite direction by a slide or incline l' attached to the floor past which
the carriage runs or the spring may be dispensed with, a double slide or two
slides may be employed to move it first in one direction and then in the reverse
direction as required.
To act as a spindle stopper the slide P is arranged to hold or place both clutches
out of gear or engagement at the same time.
Two different speeds are thus obtainable for the tin rollers and spindles and a
third speed can also be obtained in the usual way by a counter shaft driving on
to the rim shaft. In addition by a suitably shaped slide the tin roller A and
the spindles may be completely stopped during a portion of the run of the
carriage.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is―
1. A speed or driving motion whereby two speeds may be obtained for the tin
rollers and spindles of mules having the several parts constructed and arranged
substantially as described and shown with reference to either of the figs. of the
drawings.
2. In a speed or driving motion for the spindles of spinning mules the_com-
bination with the tin roller A and tin roller shaft B of the grooved pulley D the
friction cones EE¹ the clutches f f¹ the counter shaft K the pulley L thereon
the cross shaft K' and the gearing thereon the lever G¹ spring and slide P
substantially as and for the purpose described and shown.
