PROVISIONAL SPECIFICATION.
Improved Driving Gear for the Rollers of Wringing and Mangling
Machines.
We, RICHARD VARLEY, JOSEPH BUTTERFIELD, and JAMES SMгr, all of the
Firm of Varley and Company, of Cyclops Works, Keighley, in the County of
York, Machine Makers, and SAMUEL BARRETT, of the same place, Pattern Maker,
do hereby declare the nature of this invention to be as follows, that is to say:--
It relates to improved driving gear for the rollers of wringing and mangling
machines whereby the direction of motion of these rollers may be readily reversed
and that without reversing the direction of motion of the hand or power driving
wheel.
In carrying our invention into effect in accordance with one arrangement we
secure a double toothed wheel on the driving roller's shaft, one set of its teeth
forming an ordinary spur-wheel while the other set forms an internally toothed
wheel on the outside of or larger in diameter than is the said spur-wheel.
To the annular driving wheel, whether of the winch handle type or the one
driven by other power, we secure a pinion which we mount in bearings
SO that it may occupy and revolve in a position between the two
sets of teeth on the double driving wheel, at one time being in gear with
one set and so transmitting motion, when rotated in one direction, to the rollers,
while by its said bearings being moved as hereinafter described, it (said pinion)
is at another time in gear with the other set of teeth and so transmits its motion
to the rollers but in the opposite direction.
The bearings upon which the pinion and its driving wheel are mounted are
made to slide or move upon other bearings fixed to the machine's framework and
the movement transmitted to said moveable bearings is preferably effected by
an appropriately formed eccentric or crank so that when it is in one position
it will hold the pinion firmly in gear with one set of teeth while when it is
turned into the other position it will also as firmly hold it, the direction of the
force or weight that the moveable bearings exercise over the eccentric or crank
acting in both cases when the pinion is in its operating positions directly through
the dead centres of said eccentric or crank.
In accordance with an alternative arrangement we mount the driving wheel
and its pinion on a hinged bearing operated by cam, lever or notched connecting
rod devices for moving it from one position to another and retaining it firmly
in either or both of such positions. In this case the said pinion may be thus
brought from gearing directly with the tooth-wheel fixed on the roller's shait
in which position it transmits motion to said roller in one direction, to such a
position as an intermediate wheel (with which it is constantly in gear and which
is therefore carried by the same moveable bearings) will be brought into gear
with said roller-wheel by which means the motion of the said roller will be
reversed as desired.

Machines.
We, RICHARD VARLEY, JOSEPII BUTTERFIELD, and JAMES SMITII, all of the
Firm of Varley and Company, of Cyclops Works, Keighley, in the County of
York, Machine Makers, and SAMUEL BARRETT, of the same place, Pattern 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, that is to say:
It relates to an improved driving gear for the rollers of wringing and mangling
machines whereby the direction of motion of these rollers may be readily
reversed and that without reversing the direction of motion of the hand or power
driving wheel.
In order that our said invention may be readily understood, we have hereunto
appended sheets of drawings illustrative thereof, in which:-
Fig. 1 is a sectional end elevation of a wringing or mangling machine to which
our improved driving gear is applied.
Fig. 2 is part sectional front elevation of parts shown by Fig. 1.
Fig. 3 is an end elevation of parts illustrated by Figs. 1 and 2, with the hand
or driving wheel removed.
Figs. 4 and 5 are similar views to Figs. 2 and 3, but are illustrative of a
modification of our invention.
In carrying our invention into effect, in accordance with one arrangement
we secure a double toothed wheel a on the shaft 6 of the driving roller c, one
set of its teeth a¹ forming an ordinary spur wheel while the other set a² forms
an internally toothed wheel on the outside of or larger in diameter than is the
said spur wheel a¹.
To the annular driving wheel e, whether of the winch type as shown, or one
driven by other power, we secure, by means of the shaft fi, the pinion f which
we mount in bearings so that it may occupy and revolve in a position between
the two sets of teeth a¹ and a² on the double driving wheel a, at one time being
in gear with one set and so transmitting motion, when rotated in one direction,
to the rollers c and d, while by its said bearings being moved as hereinafter
described, it (said pinion f) is at another time in gear with the other set of
teeth and so transmits its motion to the rollers c and d but in the opposite
direction.
To enable the shaft f¹ to be moved as above described so that the pinion may
gear with the teeth a¹ or a² as desired, we preferably mount said shaft eccentric-
ally in the movable bearing 9, said bearing g being mounted in fixed bearings h.
It will therefore be seen that on rotating the bearing 9 by means of its handle g¹,
the shaft and pinion f may be moved to occupy the position shown in the
drawings, (wherein said pinion is in gear with the teeth a²) or they may be
lowered from such position so that the pinion may gear with the teeth a¹. Suit-
able stop pieces and g³ (shown in broken lines Fig. 3) are formed on the
bearing to come into contact with the projection h¹ on the bearing h so as to
cause the movement of said bearing to be stopped at the requisite time when the
shaft is being moved from one to the other of its operative positions. The
fixed bearings h are preferably formed of the shape shown in the drawings, so
that same may form a suitable guard for the gearings wheels.
It will readily be seen that the formation or construction of the bearings for
the shaft f, as also the crank, eccentric or like mechanism for imparting the

page_text: desired movement thereto, may be varied to a considerable extent, however we
preferably make use of those as above described.
in accordance with an alternative arrangement we mount the driving wheel e
and its pinion e' loosely ou the shaft 6 of the lower roller c, said pinion e gearing
with a wheel m mounted to revolve on a stud n fixed to the framework A of the
machine and having a pinion m¹ formed integrally therewith. This said
pinion m drives a wheel o fixed on the shaft 6 through the intermediate wheels
or pinions p and q mounted on the movable bearings r which revolve about
the stud n.
When the wheels p and q are in the position illustrated by Figs 4 and 5,
motion will be imparted from the pinion e¹ to the wheel o and consequently to
the roller in the direction indicated by the arrows, however on moving the
bearings so that the pinions p and q occupy the positions indicated at a and c
(Fig. 4), respectively, motion will be imparted to said wheel o and roller c in
the reverse direction, the pinion q having been moved out of gear with the
wheel o and the pinion been having been moved so as to gear with both the
pinion m and said wheel o.
The bearings are moved from one position to the other and held therein
by means of the rod s, having notches 2 formed therein, said notches taking
over the projection t formed on the framework A, or any suitable lever or other
mechanism may be used for this purpose.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
1. In driving gear for the rollers of a wringing and mangling machine a
wheel having two sets of teeth formed thereon as herein described, and a pinion
arranged so as to be caused to gear with one or other of such sets of teeth in
combination, substantially as herein specified.
2. In driving gear for the rollers of a wringing and mangling machine, toothed
wheels and pinions mounted as described, and intermediate toothed wheels
mounted on movable bearings and arranged to work in connection with said
toothed wheels and pinions, in combination, substantially as herein specified.
3. Driving gear for the rollers of wringing and mangling machines, the
same being constructed and arranged to operate substantially, as herein specified.
