PROVISIONAL SPECIFICATION.
Improved Feed Regulating Mechanism for Lappers of Cotton and
other Fibrous Substances, also Applicable to Drawing Frames.
We JAMES RUSHWORTH of 399 Oldham Road Failsworth near Manchester Cotton
Spinner and WILLIAM RUSHWORH of 19 Copster Hill Road, Oldham Carder do
hereby declare the nature of our said invention to be as follows:-
--
This improved speed regulating mechanism consists in the application to the
purpose of a special arrangement of Sun and Planet motion working in conjunction
with a pair of cone drums as hereinafter described.
In performing our invention and as applied to lappers of cotton, silk, worsted, jute
and other fibrous substances we secure upon the side shaft of the lappers one of a pair
of cone drams and alongside this drum key upon .the same shaft a spur wheel. This
spur
wheel gears with a planet wheel mounted upon one extremity of a spindle passing
through bosses in a sun wheel which is mounted to revolve loosely upon the side
shaft and at the other extremity of the same spindle is koyed a similar sized planet
wheel which is in its turn geared with a spur wheel (of the same size as the first
mentioned spur wheel) secured upon a long bush or sleeve capable of revolving loosely
upon the side shaft. A bevil pinion upon the other end of the sleeve gears direct with
the usual bevil wheel upon the feed rollers.
The cone drum beforementioned is arranged by an endless band to drive a corre-
sponding cone drum which is geared to the periphery of the sun wheel.
In this manner we are enabled to increase the speed of the side shaft to three times
its ordinary rate as the sun wheel during-its revolution neutralises two revolutions
of the driving wheel and so permits only one revolution to be imparted to the bush for.
driving the food rollers.
The action of this improved variable feed mechanism is as follows:-
In commencing to work the band is placed in the centre of the cone drums and in
this position the feed rollers are "timed" to be driven at the desired speed but in
case of a variation in the thickness of the lap the strap guider would be pushed either
on to the larger or smaller end of the driving cone drum and thus the speed will be
increased or diminished and so regulated to the greatest nicety.
In practice it is found that the tapper or bevil of the cone drams is only one half
that required in ordinary cone driving drums as the effect of the application of the
improved sun and planet driving mechanism is to double the effective speed of the
changing mechanism.
This improved seli regulating driving mechanism is equally applicable to regulating
the draft in the rollers of drawing frames for fibrous materials.

COMPLETE SPECIFICATION.
Improved Feed Regulating Mechanism for Lappers of Cotton and
other Fibrous Substances, also Applicable to Drawing Frames.
We JAMES RUSHWORTH of 399 Oldham Road, Failsworth near Manchester, Cotton
Spinner and WILLIAM RUSHWORTH of 19 Copster Hill Road, Oldham, Cardor do
hereby declare the nature of our said invention and in what manner the same is
to be performed to be particularly described and ascertained in and by the following
statement :-
This improved speed regulating mechanism is applicable to lappers of Cotton, Silk,
Worsted, Jute-and-other-fibrous materials and consists in the application to the purpose

page_text: of a special arrangement of Sun and Planet or differential motion working in
conjunction with a pair of cone drums as hereinafter described.
On the accompanying drawing we illustrate our improvements applied to a Lapper
of ordinary construction.
Fig. 1 is a side view of so much of a Lapper for Cotton as is necessary to illustrate
our improvements which are shewn applied thereto. Fig. 2 is a transverse section of
Fig. 1 across the line A-B and Fig. 3 is a partial plan view of Fig. 1.
In all the views a is the framework of the Lapper supporting the side shaft b
in the bracket cand driving the feed rollers through the bevil wheels c and d.
This side shaft is driven at an accelerated speed say about three times the ordinary
speed and is fitted with a differential motion working in conjunction with the cone
drums as hereinafter described.
In performing our invention we apply a spur wheelf at the extremity of the
side shaft which gears through the double spur wheel and spur pinion g¹ with
the upper cone driving pulley h. The lower cone driving pulley' is geared
through the bevil wheel and inclined shaft j carrying a four threaded worm j
with the large worm wheel k. The threads of the worm and worm wheel being
cut to an angle of about 224 degrees. Mounted in this worm wheel k are a pair
of bevil wheels 1, 1 gearing at one side with the equal sized hevil wheel m which
is keyed the side shaft b and on the other side gearing with a similar bevil wheel o
which is capable of being thrown in and out of gear with the sleeve p carrying
at its other extremity the bevil pinion c for operating the feed rollers. The sliding
clutch box permits this sleeve p to be disconnected from the bevil wheel o at
pleasure and thus enables the feeding mechanism to be stopped without stopping
the entire machine. In this manner we are enabled to increase the speed of the
side shaft to three times its ordinary rate as the worm wheel k by revolving only
once for every three revolutions of the driving wheel m so neutralises two
revolutions of such driving-wheel-and permits-only-one-revolution-to..be imparted_
to the sleeve p for driving the feed rollers.
The action of-this improved variable feed mechanism is as follows:-
In commencing to work the bands is placed in the centre of the cone drums and
in this position the feed rollers are "timed" to be driven at the desired speed but
in case of a variation in the thickness of the lap the strap guider t would be
pushed by the ordinary pedal mechanism operating the chain either on to the
larger or smaller end of the driving cone drum and thus the speed will be
increased or diminished and in proportion will be communicated to the feed rollers
the speeds of which are so adjusted to the greatest nicety.
In practice it is found that the taper or bevel of the cone drums is only one half
that required in ordinary cone driving drums, as the effect of the application of our
improved differential driving mechanism is to double the effective spoed of the
changing mechanism.
Our improvements are equally applicable to Lappers of other descriptions of fibrous
materials.
In our Provisional Specification we mention the application of our improvements
to Drawing Frames &c. but we do not propose to claim such further application.
Having thus particularly described and ascertained the nature of this our said
invention and in what manner the same is to be performed we declare that what
we claim is :—
In Lappers of Cotton, Silk, Worsted, jute and other fibrous material the use and
application of the differential mechanism working in conjunction with the cone
driving pulleys substantially as and for the purpose hereinbefore described.
