PROVISIONAL SPECIFICATION.
Improvements in Wringing and Mangling Machines.
I, THOMAS WALKER, of Regent Street, Eccles, in the County of Lancaster,
Machinist, do hereby declare the nature of this invention to be as follows:-
This invention is primarily designed to provide gearing for driving the rollers of
these machines which will permit of the position of the rollers being changed or
reversed without any alteration or addition thereto.
I construct the shafts of both rollers of equal length preferably sufficiently long
at both ends to carry gear wheels and I prefer at present to place the gear
wheels attached to the rollers at the same side of the machine as the driving
mechanism.
On the face of each of these pinions I fix studs or lugs projecting outwards.
The plate wheel instead of being fixed to the lower roller shaft I mount to run
loose on a stud or bearing carried by a bracket bolted or otherwise fixed to the
frame. On the back of this wheel I place a slide or bracket or its equivalent with
which the projection on the pinion of the lower roller engages so that when the
wheel is rotated the roller also rotates. The bracket also carries a stud for the fly
wheel and the intermediate carrier or stud wheel is carried on a stud on the frame.
The bracket is supported in any convenient way by bolts and studs.
When it is desired to remove or reverse the rollers the weight is removed the
top roller lifted out and then the bottom one. The roller that was top then takes
the place of the bottom one the projection on the gear wheel engaging with the
slide or snug on the back of the plate wheel.
If desired the pinions may be at the other side of the frame and an arm, crank,
disc or other device be provided for carrying the pin or projection by which the
rollers are caused to rotate.
Instead of lugs by which the plate wheel connects with the gear wheel on the
roller the plate wheel and the gear wheel both may be made with bolt holes or
slots and then connected together by passing a bolt or its equivalent through such
holes. To remove the rollers these bolts are unfastened and withdrawn.

COMPLETE SPECIFICATION.
Improvements in Wringing and Mangling Machines.
I, THOMAS WALKER, of Regent Street, Eccles, in the County of Lancaster,
Machinist, 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 :-
This invention is primarily designed to provide gearing for driving the rollers
of these machines which will permit of the position of the rollers being changed or
reversed without any alteration or addition thereto.
:
It consists essentially in so constructing the machine with the shafts of both
[Prine |

page_text: rollers of equal length and gear wheels thereon with projecting lugs bolts or the
like which engage with the side or back of a plate or driving wheel that the rollers
may be removed from the machine and their position reversed without changing
the gearing.
It will be fully described with reference to the accompanying drawings in which
sufficient of a wringing or mangling machine is shown to illustrate the invention.

The top roller A the bottom roller B and the frame C are of the ordinary
construction.
The shafts D and E of the top and bottom rollers A and B I form of equal
length and preferably of equal lengths at both ends of the rollers so that gear
wheels may be placed at either end of the rollers. At present I prefer to place
the gear or star wheels F and G by which the rollers are geared together at the
same end of the machine as the driving mechanism. On the face of each of the
pinions F and G I fix projecting studs or lugs ƒ and g.
If desired however the wheels F and G may be placed at the other end of
the machine and a disc or other device be applied to the shaft to connect the roller
with the driving mechanism.
The plate or driving wheel H and the fly wheel K which hitherto it has been
customary to mount upon the lower roller shaft I mount to run loose upon studs h
and k carried by a bracket L bolted or otherwise fixed to the frame C.
The studs and k may be cast or otherwise affixed to the bracket L one
projecting inwards towards the frame and the other outwards. The bracket is
supported in any convenient way such as by three stud bolts l.
The plate wheel H is driven from the fly wheel K by the intermediate carrier or
stud wheel M rotating on the bottom stud bolt which supports the bracket L.
On the back of the plate wheel H I form or attach a slide or clutch / (or its
equivalent) with which one of the lugs for g projecting from the pinions F and G
engage so that as the driving wheel H rotates the rollers are caused to rotate
thereby.
Instead of projections on the face of the pinions F and G engaging with
corresponding projections on the face of the plate wheel H the two may be formed
with holes and stud bolts g or other bolts passed through to connect the wheels
together.
One form of this modification is shown in Fig. 3 in which the plate or driving
wheel H is mounted on the stud has described in Fig. 1. Another form of this
modification is shown in Fig. 4 the plate wheel H is furnished with holes and is
bolted to the pinion G by bolts g11 by which it is supported it also carries a stud K¹
keyed cast or otherwise affixed to it upon which the fly wheel K rotates. In this
modification the bracket L may be dispensed with.
In another arrangement as shown in Figs. 6 and 7 an internal toothed wheel H¹
may take the place of the plate wheel H and the intermediate or carrier wheel M
be dispensed with. In this case the stud / carries the wheel H¹ and the fly wheel K
is supported by a bearing or socket k¹ formed in the bracket. On the back of the
wheel H I place the slide or clutch ¹ with which the projections for g on the
pinions engage.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A wringing or mangling machine having the shafts of both rollers constructed

page_text: of equal length and dimensions and carrying wheels or their equivalent provided
with projecting lugs on their face (or holes to receive bolts) in combination with a
slide clutch or stop on the side or back of a driving wheel (or holes to receive
bolts) by which they are rotated so that the rollers are capable of being reversed
in their position substantially as described.
2. In a wringing or mangling machine the combination with pinions provided with
lugs or projections on their face on roller shafts of equal length, of corresponding
lugs or projections on the driving wheel forming a slide or clutch with which those
on the pinions engage substantially as and for the purpose described.
3. A wringing or mangling machine having the several parts constructed and
arranged in combination substantially as described with reference to Figs. 1 to 5
or Figs. 6 and 7 of the drawings.
