improvements in Jacks or Gearing for Imparting Differential
Motion in Machinery for Preparing and Spinning Cotton and
other Fibres.
I, THOMAS HENRY RUSHTON, of Kay Street Works, Bolton, in the County
of Lancaster, Machine Maker, do hereby declare the nature of this invention to
be as follows:-
:-
This invention relates to further improvements in the jacks or gearing for
imparting differential motion in machinery for preparing and spinning fibres for
which Patents were granted to George Haworth and Samuel Fallows numbered
11938 of 1888 and to the said Samuel Fallows and George Haworth numbered
15570 of 1889.
In carrying my present improvements into effect I rearrange various parts of
the mechanism specified in the above Patents. The wheel marked 13 described in
the Specification and illustrated in the drawings to Patent No. 15570 of 1889 I
place inside the cam 14 thereby causing the teeth 11 to be put on the opposite side
of the disc 3. I dispense with the forks 1, grooves 7, in the ball 6, and the disc 4
specified in the said Patent and in lieu thereof I cast or attach on or to the disc 3,
snugs, pins or studs which engage in slots or forks formed with or attached to the
ball 6 or the boss of the said ball.
may reverse this by using the suugs pins or studs on or attached to the bail
and engaging in slots or forks which may be formed with or attached to the disc.
The ball 6 prefer to make hollow and elongate the boss of the ball on the
shaft 10. This boss may be made hollow for a certain length to avoid friction and
to assist the lubrication. Fastened to this boss so as to revolve with it I employ a
cover extending over the whole mechanism. On the inside of this cover are a
number of inclined wings or projections for purposes of lubrication. The inside of
the cover is also made inclined or taper being larger in diameter at that end in
which the wings are placed.
For purposes of lubrication holes for the reception of oil are made through the
boss of the cover and extending through the elongated boss of the ball into the
hollow of the said boss. The oil poured through these holes flows through
the hollow portion of the elongated boss into the hollow of the ball. A hole is
made through this ball through which the oil is allowed to lubricate the bearing
surfaces of the disc and ball.
When in motion and owing to the inclination of the inside of the cover the oil
is kept to the end largest in diameter where it is most required and drips from the
inclined wings or projections on the inside of the cover on to those working parts
which require lubricating thus ensuring a constant lubrication without waste.

Improvements in Jacks or Gearing for Imparting Differential
Motion in Machinery for Preparing and Spinning Cotton, and
other Fibres.
I, THOMAS HENRY RUSHTON, of Kay Street Works, Bolton, in the County
of Lancaster, Machine Maker, 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 :-
This invention relates to further improvements in the jacks or gearing for
imparting differential motion in machinery for preparing and spinning fibres for
which Patents were granted to George Haworth and Samuel Fallows numbered
11938 of 1888 and to the said Samuel Fallows and George Haworth numbered
15570 of 1889, and the objects of my improvements are to simplify and arrange in
a novel combination and to provide improved means of lubricating such gearing or
mechanism.
In carrying my present improvements into effect I rearrange various parts of the
mechanism specified in the above Patents. The wheel marked 13 in the
Specification and illustrated in the drawings to Patent No. 15570 of 1889 I place
inside the cam 14 thereby causing the teeth 11 to be put on the opposite side of
the disc 3. I dispense with the forks 1, grooves 7 in the ball 6, and the disc 4
'specified in the said Patent and in lieu thereof I cast or attach on or to the disc 3,
snugs, pins, or studs which engage in slots or forks formed with or attached to the
ball 6 or the boss of the said ball.
I may reverse this by using the snugs pins or studs on or attached to the ball
and engaging in slots or forks which may be formed with or attached to the disc.
The ball 6, I prefer to make hollow and elongate the boss of the ball on the
shaft 10. This boss may be made hollow for a certain length to avoid friction
and to assist the lubrication. Fastened to this boss so as to revolve with it I
employ a cover extending over the whole mechanisın. On the inside of this cover
are a number of inclined wings or projections for purposes of lubrication. The
inside of the cover is also made inclined or taper being larger in diameter at that
end in which the wings are placed.
For purposes of lubrication holes for the reception of oil are made through the
boss of the cover and extending through the elongated boss of the ball into the
hollow of the said boss. The oil poured through these holes flows through
the hollow portion of the elongated boss into the hollow of the ball. A hole is
made through this ball through which the oil is allowed to lubricate the bearing
surfaces of the disc and ball.
When in motion and owing to the inclination of the inside of the cover the oil
is kept to the end largest in diameter where it is most required and drips from the
inclined wings or projections on the inside of the cover on to those working parts
which require lubricating thus ensuring a constant lubrication without waste.
Referring to the accompanying drawings forming part of this Specification
Figure is a sectional elevation of my improved differential gearing and so
much only of a flier frame as is necessary to illustrate the application of said
gearing to the same, and
Figure 2 is a sectional elevation showing the differential gearing in detail.
The differential gearing is carried by the driving shaft a of the machine, and
consists of the following parts :-
A toothed wheel is fixed upon the driving shaft a preferably by means of a
nipping screw c as shown, and at one point gears into a toothed disc d which has
its teeth set in a ring eccentrically and diagonally to the axis of the shaft a, the
number of teeth in the ring being greater than the number of teeth on the wheel b.

page_text: The
The interior of the disc d is cupped and fashioned to fit at the required angle
upon the ball shaped portion of a long boss e which is mounted loose upon the
shaft a.
The disc d is maintained in its proper working position upon the ball of
the boss e by means of a flanged sleeve f, the flanged portion of which is cut off
at an angle corresponding to the inclination of the disc d to the shaft a.
flanged sleeve is mounted loose and is maintained in its proper position upon the
shaft a by means of a fixed collar y. The disc has formed or fixed on its back,
studs which engage with corresponding slots in a flange e on the boss e.
Fastened on the boss e by a nipping screw is a cover which extends over and
incloses the whole mechanism so as to exclude dust and dirt. On the inside of this
cover i near one end are a number of inclined wings or fins, and the inside of
the cover is inclined or tapered being larger in diameter at that end in which
the wings are placed. A hole for the reception of oil is made through the
boss of the cover i, and extends through the boss e into the interior of the same,
which is made hollow for part of its length in order to diminish friction and
facilitate lubrication. The oil poured through the hole flows through the
hollow portion of the boss e, and through a hole e in the ball portion, whereby the
bearing surfaces of the disc d and ball are lubricated.
When the mechanism is in motion and owing to the inclination of the interior of
the cover the oil therein is kept to the end largest in diameter, where it is most
required and drips from the inclined wings on to those working parts which
require lubricating, whereby constant lubrication without waste is insured.
The mechanism is actuated in the usual way, that is to say, the motion of the
driving shaft a is communicated by the twist wheel and gears m, n, to the top
cone o which drives by a belt p the bottom cone whence motion is transmitted by
the train of gears 3, s, s, s³, to the jack shaft t which drives by a gear u, a pinion v
keyed on the sleeve f. The toothed wheel b, being fixed on the driving shaft a,
drives the toothed disc d which by its studs d' drives the boss e from which motion
is transmitted to the bobbins in the usual way by gearing, not shown, from the
wheel w keyed on the boss e.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The combination with the toothed wheel & fixed on the driving shaft, and the
flanged sleeve driven from the bottom cone, of the toothed disc d, studs d',
flanged ball boss e, cover and bobbin wheel w all arranged and operating
substantially as herein set forth.
2. The combination with the cover i fixed upon the ball boas e, of the wings ¹
for lubricating the working parts inside said cover, and the hole for supplying
oil to the interior of the ball boss and bearing surface of the disc d substantially
as herein set forth.
3. The general arrangement and combination of parts embodying my improve-
ments substantially as and for the purposes herein described and as shown.
Dated this 13th day of March 1894.
