EDMUND TWEEDALE, SAMUEL TWEEDALE & JOSEPH SMALLEY Machine
Makers Castleton near Manchester do hereby declare the nature of this invention
to be as follows:-
This invention consists of an improved construction, and arrangement of
apparatus for purpose aforesaid, in which one of the bevel wheels is dispensed
with, the weight of the apparatus lessened, & centrifugal action reduced to a
minimum.
According to this our invention we construct on the driving shaft a boss which
forms a bearing for a cross shaft, on one end of which is secured a bevel wheel
which gears with the bevel wheel driven from the conc drums, and on the other
side with a similar bevel wheel to that driven from the cone drums, on the boss
of which latter bevel wheel is secured a spur wheel, that drives the bobbins.
The opposite end of the cross shaft to which the bevel wheel is attached is.
made the requisite weight to counter balance the centrifugal force of the bevel
wheel when revolving.
The action is as follows; On the driving shaft commencing to rotate it carries
the bevel wheel and the cross-shaft round with it and supposing the bevel wheel
driven from the cone drums to be stationary, one revolution of the driving shaft
will cause the bevel wheel, on the cross shaft to give two revolutions, in the
same direction as the driving shaft, to the bevel wheel which drives the bobbins,
and in consequence the size of the spur wheel, driving the bobbins, is reduced
to one half the usual diameter. Any rotation of the bevel wheel driven from
the cone drums, alters the speed of the wheel that drives the bobbins and so.
regulates the winding.

Improvements in "Jacks" or Apparatus for Ensuring Differential
Motion on Slubbing and Roving Frames.
We, EDMUND TWEEDALE, SAMUEL TWEEDALE, and JOSEPH SMALLEY
Machine Makers, Castleton, near Manchester, do hereby declare the nature of
this invention and in what manner the same is to be performed, to be par-.
ticularly described and ascertained in and by the following statement:-
This invention consists of an improved construction and arrangement of
apparatus for purpose aforesaid in which one of the bevel wheels is dispensed
with, the weight of the apparatus lessened, and centrifugal action reduced to a
minimum.
According to this our invention, we construct a boss on the driving shaft which
forms a bearing for a cross shaft, on one end of which is secured a bevel wheel
gearing with the bevel wheel driven from the cone drums, and on the other side
with a similar bevel wheel to that driven from the cone drums, on the boss of which
latter bevel wheel is secured a spur wheel employed to drive the bobbins. The
opposite end of the cross shaft to which the bevel wheel is attached is made the
Pine 11

revolving.
In order that our invention may be better understood, we will make reference to
the accompanying sheet of drawings which is sectional elevation of our improved
"jack" or differential motion employed in slubbing and roving frames. A represents
the driving shaft provided with a boss B through which is placed a stud or cross
shaft C. A bevel wheel D is made secure on one end of the said cross shaft, whilst
on the opposite end of said shaft is a balance weight E for neutralizing the
centrifugal action of the bevel wheel D whereby the parts are evenly balanced.
Two bevel wheels F and G are mounted loosely on the main shaft A both of which
wheels gear with the bevel wheel D. The former bevel wheel F is driven by spur
wheel H from the ordinary cone drums which regulate the winding of the yarn:
The bevel wheel G through the intervention of spur wheel I and ordinary swing
wheels drives or gives rotary motion to the bobbins. The part marked projects
from the boss of the toothed wheel I and is employed as a shield or cover to the
series of bevel wheels.
The action is as follows:-On the driving shaft A commencing to rotate, it
carries the cross shaft C together with the bevel wheel D around with it, and
supposing the bevel wheel F which is driven from the cone drums to be stationary,
one revolution of the driving shaft A will cause the bevel wheel D on the cross
shaft C to give two revolutions to the bevel wheel G and spur wheel I (which
drives the bobbins) in the same direction as the driving shaft, consequently the
diameter of the said spur wheel is reduced to one half its usual diameter and
the number of bevel wheels are lessened by one.
Any variation of the speed of wheel H driven from the cone drum is trans-
mitted in relative proportion to the spur wheel I which drives the bobbins,
whereby their speed is regulated accordingly.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
:-
Firstly. In "jacks" employed in slubbing and roving frames, the mounting of a
bevel wheel and counterbalance weight on the cross shaft C as shewn and
described.
Secondly. In "jacks" employed in slubbing and roving frames, the combination
and arrangement of bevel and spur wheels, shewn and described herein, or any
mere modification thereof.
