PROVISIONAL SPECIFICATION.
Improvements in the Method of Driving the Rollers of Washing,
Wringing, and Mangling Machines.
We, JOHN EDMONDSON, and JOSHUA WHALLEY, both of Eagle Iron Works,
Keighley, in the County of York, Machine Makers, do hereby declare the nature
of this invention to be as follows:-
The object of this invention is to arrange the driving gear in such a manner
that the friction of the machine is reduced, and to place all the wheels for
operating the rollers, at one end of the machine instead of at both, as hitherto,
also to so protect them that it is impossible for a person to be injured by being
caught with the teeth of the wheels.
We accomplish our object in the following manner: On the shaft of the
bottom roller, we secure a spur wheel having internal teeth and on the back of
said wheel is another spur wheel with the teeth arranged so as to gear with a
wheel secured on the shaft of the top roller. The first named wheel is operated:
by a pinion mounted on a shaft supported by a guard bracket bolted to end
frame and which by preference is made to enclose all the wheels.
By arranging the wheel in the manner described, the teeth of the driving
pinion work direct into the teeth of the wheel on the bottom roller shaft, instead.
of having to transmit the motion to the rollers through another wheel and pinion
as is the case with machines constructed in the ordinary manner.

COMPLETE SPECIFICATION.
Improvements in the Method of Driving the Rollers of Washing,
Wringing, and Mangling Machines.
We, JOHN EDMONDSON and JOSHUA WHALLEY both of Eagle Iron Works,
Keighley in the County of York, Machine Makers, 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
to say:-
The object of this invention is to arrange the driving gear in such a manner that
the friction of the machine is reduced while all the wheels for operating the rollers
are placed at one end of the machine instead of at both as heretofore, the covering
or protection of these wheels being such as to render it impossible for any person
to be injured by them when in operation as has often been the case.
In the accompanying sheet of drawings
Figs. 1 and 2 are respectively end and front elevations of a portion of a machine
shewing the arrangement and application thereto of our improved driving gear, the
covering for the wheels being omitted so that said wheels might more clearly
be seen.
Figs. 3 and 4 are similar views to Figs. 1 and 2 respectively but shew the cover
or guard for the wheels, in position. In Fig. 4 the hand wheel is also shewn in
position, while in all the other drawings it is omitted.
We attain the object. of our invention by rigidly mounting, as by keying or
otherwise, an internally toothed spur wheel a upon the shaft of the bottom

page_text: roller c.
To the back of this wheel a is secured a wheel d which is arranged to
gear with the wheel e rigidly mounted upon the shaft of the top roller.
In gear with the wheel a is a pinion mounted on the pin or shaft & carried by
the guard or cover which is secured by bolts m m¹ to the end frame n of the
machine, and which is made to cover all the toothed wheels as is shewn by Figs. 3
and 4.
On. the pink is securely; mounted the. hand wheel. p so that, by imparting rotary
motion thereto, the wheels-h, ad andre are revolved causing, the rollers c and y to
rotate as is desired.
C
The arrangement of gearing above described entirely obviates the use of
intermediate gearing wheels as at present usually employed and so dispenses with
the extra amount of friction that must necessarily accompany such extra gearing.
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 mechanism the combination of an internally toothed spur wheel
having an ordinary spur wheel attached to the back of it, a pinion for imparting
motion to said internally toothed wheel, and means for supporting said pinion,
said means being arranged to cover all the toothed driving wheels substantially as
specified.
2: The arrangement and combination of gearing wheels and means for supporting
same substantially as herein set forth and for the purpose specified.
3. The driving gear for washing and like machines substantially as herein
specified.
