Improvements in Differential and other Gearing employed in
Machinery for Preparing and Spinning Cotton and other
Fibres.
I, ROBERT TAYLOR, Junior, of the firm of Asa Lees and Company Limited,
of Soho Iron Works, Oldham, in the County of Lancaster, Engineer, do hereby
declare the nature of this invention to be as follows:-
My invention relates particularly to what is known as the jack in the box
mechanism but it relates also to the means for imparting motion from the main
driving shaft of the machine to the bobbins.
In one arrangement of mechanism for transmitting differential motion from the
driven cone to the bobbins I mount loosely on the driving shaft a bevel wheel
driven in any convenient manner from the cone; this bevel wheel gears into a
bevel wheel or preferably a pair of bevel wheels each provided with two sets of
teeth and each bevel mounted upon a stud projecting from a boss which is secured
to the shaft. The outer row of teeth on the bevels gear with teeth cast upon the
inner face of a casing fitted loosely upon the boss of the bevel on the driving
shaft; this casing is made in two parts the boss of the faceplate which forms one
part being fitted loosely upon the driving shaft, and on this boss is secured the
gear from which the bobbins are driven.
In a modification of the above arrangement the studs with the bevel wheels are
carried round by the driven cone and a bevel wheel secured on the driving shaft
gives motion to the inner row of teeth on the double bevel wheels, the outer row
transmitting the variable motion to a bevel gear loose on the shaft and carrying
a gear by which the bobbins are driven.
Instead of the usual "swing" arrangement which consists of two levers I
propose to use three levers or links the first of which is hinged at one end to the
axis of the gear on the driving shaft and at the other end to the first carrier;
the second link is hinged to the first and second carriers and the third link is
hinged to the second carrier and to the axis of the gear on the bobbin shaft which
rises and falls with the lifting rail.
On one of these links I have a stud which enters a slot in a bracket fixed to the
frame side and so guides the parts and keeps them steady.
In some cases the second carrier wheel would gear into a pinion mounted on the
lifting rail and this pinion would transmit the motion to the bobbin gear.

Improvements in Differential and other Gearing employed in
Machinery for Preparing and Spinning Cotton and other
Fibres.
1, ROBERT TAYLOR, Junior, of the firm of Asa Lees and Company Limited,
of Soho Iron Works, Oldham, in the County of Lancaster, Engineer, 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 :-
My invention relates particularly to what is known as the jack in the box

page_text: mechanism but it relates-also-to the means for imparting motion: from the main
driving shaft through the jack in the box, mechanism to the bobbins.
And in order that my invention may be fully understood and readily carried
into effect I will describe the accompanying, two sheets. of drawings reference being
had to the figures and letters, marked (thereon.
Figure 1 is a sectional elevation of one arrangement of my improved differential
gearing.
Figures 2 and 3 are similar views to Eigal of two alternative arrangements.>.
Figure 4 is a view of my improved "swing" arrangement for carrying the
gears which transmit motion to the bobbins.

In the first arrangement of mechanism illustrated by. Fig. 1. for transmitting,
differential motion from the, driven cone to the bobbins, a; designates,a,pinion.
which is driven by gearing, not shown, from the driven cone; the,pinion a is fixedi
upon the long boss of a bevel gear which is mounted loosely upon the driving,
shaft c. The bevel wheel 6 gears into a pair of bevel wheels d (or it might be,
into a single bevel wheel only) 'each provided with two sets of teeth d½ d².respect..
tively, and cach, bevel wheel d being mounted upon a stude projecting from a
bosse fixed upon the driving shaft c. The bevel wheels d are held in position on
their studs e by means of washers and screws y or by other suitable means. The
outer row of teeth, on the bevel wheels d gear with teeth, cast upon the inner...
face of a casing, fitted loosely upon the boss of the bevel gear b; this casing.
is made in two parts, connected together by screws bolts or equivalent means,+
and the boss of the part h¹ is, fitted loosely upon the driving, shaft. and, on this,
boss is secured the gear from which the bobbins are driven.
"
"
In operation the pinion. a being driven carries round with it the bevel gear.
and the latter drives by the inner row of teeth d the pair of, bevels d which thus
receives rotatory motion on their axes the studs e, in addition to their revolving motion
around the driving shaft c, consequently the outer row of teeth on the bevels d...
impart a differential motion to the casing with which they gear and so to the
spur wheel fixed on the part h'.
T
".

In the alternative arrangement illustrated by, Fig. 2. the construction is
substantially the same as in that already described; but in this case instead of the
bevel gears each with two rows of teeth, two pairs of separate, bevel, gears di d
are employed, fixed upon studs e, which are supported in a bracket k the boss, of
which is secured to the driving shaft c by means of a screw l.
In this instance also the part h of the casing is dispensed with and the teeth,
with which the bevels d' engage are made upon the part
с
In the modification illustrated by Fig. 3 the studs e with the bevel wheels dare
carried round by the gear a which is driven from the driven cone as before, and
the bevel wheel in this case is fixed upon the driving, shaft c instead of being,
loose thereon and gives motion to the inner row d' of teeth on the d
double bevel
wheels d, the outer row d² transmitting the differential or variable motion to the
part hand gear j by which the bobbins are driven.
In the improved swing. arrangement illustrated by Fig. 4 instead of the
usual combination of two levers propose to use three links or levers m, n, o,
respectively, of which the link m is binged at one end to the axis of the gear j
on the driving shaft c and at the other end to the axis of the first carrier p; the
second link n is hinged to the first carrier p and the second carrier q, and the
third link is hinged to the second carrier q.and to,the axistof gear s..onsthe bobbin
shaft whichi.gears with the other..bobbin gear.u. and trises and falls with the
lifting rail.
On one of these links in, this case on the link.n, I have a stud 10, which entersta.
slot in a bracket a fixed, to the frame sidey and so guides the, moving parts and
keeps them steady.
In some cases the second, carrier, wheel would gear into a pinion, mounted on
the lifting rail, and this pinion would transmit the motion. to the first-bobbins
gear

page_text: 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 driven pinion a and bevel gear 6 loose upon the
driving shaft c, of the double bevel gears d each with two rows of teeth or the
single bevel gears d² d said gears d revolving around the shaft c, the inner rows of
teeth gearing with the driven bevel gear 6 and the outer rows d³ with teeth on
the part or which is mounted loosely upon the shaft c and carries a gear j from
which the bobbins are driven, all combined arranged and operating substantially
in the manner herein described with reference to Figs. 1 and 2.
2. The combination with the driven pinion a mounted loosely upon the driving
shaft and carrying the studs e and bevel gears d, of the bevel gear 6 fixed upon
the driving shaft c and driving the inner rows of teeth d' on the bevel gears d, the
outer rows d' of which drive the part h' on which is fixed the gear ; from which
the bobbins are driven all combined arranged and operating substantially in the
manner herein described with reference to Fig. 3.
3. The combination of parts constituting the improved "swing" arrangement
substantially as herein described with reference to Fig. 4.
