and Mangling Machines.
I, GEORGE WHALLEY, of Tower House, Keighley, in the County of York,
Machine Maker, do hereby declare the nature of this invention to be as follows:-
My invention relates to certain improvements in the driving motion fitted to
wringing and mangling machines, and has for its object, the arrangement of tho
mechanical parts in such a manner, that the gearing is more compact than when
the power is transmitted with the ordinary spur and pinion wheels as is now the
cominon practice; and to so construct and guard the wheels, that all danger of a
person being caught by the teeth of the wheels is removed.
In carrying out my invention, I secure to the end of the machine, placed
concentric to or with the roller spindle, an internal toothed spur wheel; and gear
with the same, a spur wheel of less diameter which is placed upon a boss of the
usual driving wheel. This boss in made eccentric and is free to revolve in the
centre hole of the spur wheel, which as the eccentric rotates, travels around
the fixed internal wheel, and having fewer teeth makes a portion of a revolution for
each revolution of the eccentric.
At the back of the spur wheel is cast or secured a pinion which rotates inside
another internal wheel that is secured on the roller spindle, the teeth gearing with
the teeth of the internal wheel, thereby causing it and the rollers to rotate. Or
instead of casting or securing the before mentioned pinion at the back of the spur
wheel, I can accomplish my object by casting or securing the internal wheel
thereto, and keying the pinion on the roller spindle, by which arrangement the
internal wheel at the back of the spur wheel will revolve around the pinion on the
roller spindle, and thereby cause the rollers to rotate; in either case the top and
bottom rollers are geared together, all arranged in a compact form and covered by
a guard, thereby rendering it impossible for a person to be injured by the teeth of
the wheels.

I, GEORGE WHALLEY, of Tower House, Keighley in the County of York 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:-
My invention relates to certain improvements in the driving motion fitted to
wringing and mangling machines, and has for its object the arrangement of the
mechanical parts in such a manner, that the gearing is more compact than when
the power is transmitted with the ordinary spur and pinion wheels as is now the
common practice, and to so construct and guard the wheels that all danger of a
person being caught by the teeth of the wheels is removed.
In describing my invention, reference is made to the accompanying drawings, in
which Fig. 1 represents a front view of such portions of a wringing machine as are
required to describe my invention, which is shewn in section cut in a vertical
direction through the centre, and Fig. 2 is a front view of the gearing, the wheel
on the guard plate, wheel sleeve, and eccentric being in section.
In carrying out my invention, I secure at the end of the machine on the roller
spindle A and concentric therewith, an internal toothed spur wheel B, and gear
with the same a spur wheel C of less diameter, and having a long boss or sleeve
which is placed upon a projecting boss D on the usual driving wheel E. This boss
is made eccentric, and on turning the driving wheel E, revolves in the centre hole
of the sleeve of the spur wheel C, causing the said wheel to travel round the
internal wheel B fixed on the roller spindle.
The wheel C as before described is prepared with teeth on the circumference,
and has also internal teeth concentric therewith, which gear with the teeth of a
fixed non-rotating pinion F cast to the guard G, which is secured to the machine
frame H by bolts, so that the said teeth are concentric with the roller spindle.
The action of the apparatus is as follows:-On turning the driving wheel E, the
eccentric D carries the wheel C around with it, the pick or throw of which being
such, that the teeth of the wheel C on the full side of the pick or throw of the
eccentric are in every portion of a revolution the same depth in gear with the
teeth of the wheel B; and the internal teeth of the wheel C the same depth with
the teeth of the fixed or non-rotating pinion F on the guard G; the pinion F
having one tooth less than the internal wheel C with which it gears, and the
external teeth of the said wheel C one tooth less than the internal wheel B, or other
variations in the number of teeth may be used by making the stroke or pick of
the eccentric in accordance therewith, by which I obtain a differential motion
proportionate to the variation in the number of teeth.
On turning the driving wheel E, the internal teeth of the wheel C rotate around
the fixed or non-rotating pinion F, and having more teeth, alter their respective
positions every revolution, as do also the external teeth of the said wheel with the
internal wheel B, thereby turning the rollers K in the usual proportion for such
machines of eight revolutions of the driving wheel E to one of the rollers; the top

page_text: and bottom rollers being connected together by the wheel J gearing with the
teeth J on the back of internal wheel B; the whole of the gearing being at one end
and enclosed within the guard G, renders it impossible for a person to be injured
by the teeth of the wheels.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed I declare that what
I claim is:-
°
The combination of the wheel B with the wheel C, eccentric D, pinion F and
guard G, substantially in the manner shewn and described, and for the purpose set
forth.
