PROVISIONAL SPECIFICATION.
Improvements in Jacks or Gearing for Imparting Differential Motion
in Machinery for Preparing and Spinning Fibres.
We GEORGE HAWORTH of 12 Audley Range Blackburn in the County of
Lancaster, Card Master, and SAMUEL FALLOws of Ewwood Works, Blackburn
aforesaid, Spindle and Flyer Maker do hereby declare the nature of this invention
to be as follows:-
This invention is designed to effect economy of construction and in the working
of appliances above referred to, and comprises a new and improved construction,
combination, and arrangements of parts.
On the jack shaft is a ball or sphere one part of which is enclosed by a cavity
formed in a disc, the other part being enclosed by a cup plate fastened to the
face of the disc. The ball forms a surface on which the disc can revolve and
oscilate. The inner face of the disc is provided with bevel teeth gearing with like
teeth of a bevel wheel on a long collar and which wheel is enclosed by a hollow
boss gearing with the disc by means of teeth recesses and pins, or other like
connection. Behind the disc which works on the ball or sphere, is a plate through
which the ends of adjusting screws project and by means of which, or by cam
surfaces the disc is inclined thereby securing the requisite connection and motions
of the disc and wheels without the use of an eccentric as heretofore, the usual
long collars and wheels for transmitting the varied motions and gearing to the
spindles and to the bobbins are employed.
In lieu of the ball on the jack shaft, the disc plate may have a hole or eye
through its centre, and be received and work on and between two angled plates on the
jack shaft.

Improvements in Jacks or Gearing for Imparting Differential Motion
in Machinery for Preparing and Spinning Fibres.
We GEORGE HAWORTH of 12 Audley Range, Blackburn in the County of
Lancaster, Card Master, and SAMUEL FALLOWS of Ewwood Works Blackburn
aforesaid, Spindle and Flyer 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 is designed to effect economy of construction and in the working
appliances above referred to, and comprises a new and improved construction,
combination, and arrangement of parts.
On the jack shaft is a ball or sphere one part of which is enclosed by a cavity formed
in a disc, the other part being enclosed by a cup plate fastened to the face of the
disc. The ball forms a surface on which the disc can revolve and oscillate. The
face of the disc is provided with bevel teeth gearing with like teeth of a bevel wheel
on a long collar and which wheel is enclosed by a hollow boss gearing with the disc
by means of teeth or by cam surfaces the disc is inclined thereby securing the
requisite connection and motions of the disc and wheels without the use of eccentric
as heretofore, the usual long collars and wheels for transmitting the varied motions
and gearing to the spindles and to the bobbins are employed.

its centre and be received and work on and between two angled plates on the jack
shaft.
Such being the nature and object of this our said Invention the following is a
complete description of same reference being had to the accompanying drawings in
which
Fig. 1 is a general view or elevation of the "Jack" complete.
Fig. 2 is a plan view, or a view of fig. 1 turned one fourth part of a revolution.
Fig. 3 is a longitudinal section enlarged scale about full size shewing the whole
of the parts in position.
Figs. 4 to fig. 11, inclusive, are views of the several parts, drawn apart, for purpose
of clearly illustrating the construction thereof.
Fig. 12, illustrates jack in position and an arrangement of gear suitable for appli-
cation of Jack to a roving or slubbing frame.
At 1 is the jack shaft on which is the ball 2, enclosed on one side by a cavity 3
formed in the disc 4 the other part of the ball 2 being enclosed by the cup plate 5
secured by the set screws 6 to the face of the disc 4. (see fig. 4).
The ball 2 forms a surface on which the disc 4 can revolve and oscillate. The
face 7 of the disc 4 is provided with teeth 8 gearing with teeth 9 of the bevel
wheel 10 on the long collar 11. The teeth 12 of the face 13 of the disc 4 gear with
the teeth of the wheel 14, which is fast on the shaft 1 and is enclosed by the hollow
boss 15 the rim 16 of which is bevelled or oblique and coincides with and bears
upon the inner face 17 of the disc 4 projecting or extending beyond the teeth 8
and 12, whereby the teeth 8 and 12 of disc 4 are kept in gear with the wheels 10
and 14. At a are runners on which the cam surface 16 bears and prevent any
rubbing friction between such surfaces and the surface 17 of the disc 4.
The jack may be geared up to in any suitable manner according to the purpose to
which it is to be applied, for example in connection with a slubbing intermediate or
roving frame.
A driving pulley A on the jack shaft 1 operates the latter and at its other end is.
the twist wheel B gearing with a carrier wheel C, latter gears with wheel D on top
cone shaft E, the bottom cone F drives the bevel gear G on an upright shaft 11
and by mitre or bevel wheel J gears with a like wheel K on the collar L of the
cam 15, the cam surface 16 bears on the inner face of the disc 17 and so keeps the
teeth 8 in gear with 10 and the teeth 12 in gear with 14 and on the long collar or
sleeve 11 is a wheel gearing with the ordinary train of wheel connected with the
bobbin wheels N.
The action is as follows:—
The jack shaft runs at uniform speed so likewise the wheel 14 which is fast thereon,
say for example the latter has 36 teeth and the wheel 12 has 40 teeth and that 8 and 9
have each 36 teeth, the jack shaft would make 10 revolutions the long collar
would make 9, losing 1 revolution in 10, that is so long as the cam does not
revolve but if the cam is caused through the action of the cones to revolve, the
variation or differential motion required is transmitted to the bobbins suitable to their
changing and increasing diameter.
A gain of speed may be obtained by reversing or turning the disc 7 so as to
bring its 36 teeth (8) into gear with 36 teeth of 14 and the 40 teeth of 12 gear with
the 36 teeth of wheel 10 and there is a gain of one revolution in 10. This difference
can of course be further varied either to slower or quicker according to the number
of teeth on the several gearing surfaces. The change from losing to gaining being
available at will through the mere reversal or turning round of the parts shewn by
fig. 4 which can be slided off and on the shaft at will for purpose of effecting such
change. It will thus be seen that the jack described affords facilities for either the
bobbins to lead, or by the reversal as described of part of fig. 4 it is available for
frame whereon the flyer leads.

page_text: Having now particularly described and ascertained the nature of this our Inven
tion and in what manner the same is to be performed we declare that what we
claim is :-
The general construction, combination and arrangement of parts constituting the
improved "Jack" or differential motion operating in manner set forth and as fully
described herein and illustrated by annexed drawings.
