WO WILLIAM EDWARD SMITH of 6 Harleston Street Fitter, and GEORGE
ROBINSON, 1 Burngreave Road, Surgeon, both of Sheffield in the County of
York do hereby declare the nature of our said invention for IMPROVEMENTS IN
ADJUSTABLE GEARING FOR THE ROLLS OF MANGLES AND WRINGING MACHINES
to be as follows:-
Our invention of improvements in adjustable gearing for driving the rolls of
Mangles and wringing Machines is carried out as follows.
We fit upon the ends of the roller axles, suitable pinions or toothed wheels, and
upon the mangle side (or upon an attachment thereto) we fix a wheel gearing into
one of the beforementioned pinions and also an adjustable pinion gearing into both
the beforementioned wheel and the pinion upon the other roller axle.
The said wheel has a fixed centre and is geared into the pinion upon the :bottom
roll, the intermediate or adjustable pinion revolves in bearings having a sliding
motion in segmental grooves, the said grooves being struck from the centre of the
beforementioned wheel.
The intermediate adjustable pinion is kept in gear with the wheel and the
pinion upon the top roller axle, by means of spiral or other suitable springs placed
at the back of the bearings and set up by screws.
We prefer to place our arrangement of adjustable gearing at the side of the
mangle opposite to the handle and flywheel, as being most convenient, but it may
be fixed to the other side if desirable.
By the arrangement before described it will be seen that as the rolls vary in
distance from each other, the adjustable or compensating pinion is either forced
back, or is forced forward by the springs, as the case may be, and is thus kept
properly in gear with the wheel and the roll pinion.
The object of our adjustable gearing is to keep the rolls properly geared (by
means of the intermediate pinion) when either reduced in diameter by being turned
down on account of wear, or when separated by clothes passing between them.

and Wringing Machines.
We WILLIAM EDWARD SMITH of 6 Harleston Street Fitter, and GEORGE
ROBINSON, 1 Burngreave Road Surgeon, both of Sheffield in the County .of
York do hereby declare the nature of our invention for IMPROVEMENTS IN
ADJUSTABLE GEARING FOR THE ROLLS OF MANGLES. AND WRINGING MACHINES
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
3
Our invention of improvements in adjustable gearing for Mangles and Wringing
Machines has for its object to keep the rollers properly geared together, although
the relative position of the axles of the rollers may be changed, as when they are
moved apart by the passage of clothes between them, or brought nearer together
by reducing the diameter of the rolls when they are worn or damaged.
In order that the manner in which we propose to carry our invention into
practical effect may be clearly understood we will describe the same with reference
to the accompanying sheet of drawings.
Figs 1 and 2 are an end and front elevation of a Mangle made according to our
invention.
Fig. 3 is a side elevation of our invention arranged as an attachment, to be fixed
to an ordinary Mangle.
Fig. 4, is a modification in the arrangement of the connecting rods, outside the
frame.
Fig. 5, shows one connecting rod inside and one outside the frame.
In carrying out our invention as applied to a Mangle for example, as illustrated
in the drawings Figs 1 & 2, we fit upon the ends of the roller axles, suitable toothed
wheels A. & A¹ and upon the mangle side we fix a wheel B gearing into the wheel A¹
upon the bottom roller.
An adjustable wheel C, gears into the teeth of the wheel B, and the wheel A; it
revolves upon a sliding stud having a to and fro motion in a segmental groove D
formed in the standard or side of the mangle.
The axes of the three wheels A, C, and B, are retained at the required distances
from each other to keep the teeth properly in gear by means of the connecting
rods E & F, or by a double set arranged as shown in Fig. 4 or as in Fig. 5. It will
thus be apparent that when the wheel A is raised by clothes passing through the
rollers, the wheel C will be drawn inwards and retain its teeth in their relative
position both with the stationary wheel B, and the wheel A.
The reverse action occurs when the rollers are reduced in diameter, and the
wheel A is in consequence lowered.
Instead of the connecting rods E and F, we may if desirable use a spring device
as shown in Fig. 3 or its equivalent to retain the adjustable sliding wheel C,
properly in gear with the teeth of the wheels A and B, but in this arrangement the
centre of the wheel A, should always be below the centre of the wheel B.

page_text: The wheels in Fig. 3 are shown fixed to a separate casting or attachment G, which
is intended to be fastened by screws or other similar means to the frame or standard
of an ordinary mangle or wringer.
We do not bind ourselves to any particular size of wheels, nor to the shape of
the attachment as shown in Fig. 3, as these may be varied to suit the circumstances
of the case; the wheels may also be fixed at either side of the machine as is found
most suitable.
By adding another set of wheels, our automatic or selfadjusting gearing may be
readily adapted to a three-roller mangle.
•
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed and put into practice,
we declare that what we claim is
1st In Wringing and Mangling Machines an arrangement of automatic adjustable
gearing for the purpose specified and substantially as hereinbefore described and
illustrated.
2nd In connection with the rollers of Mangles and wringing machines, the self-
acting compensating gearing consisting of the fixed wheel B, and the moveable
wheel C, working into each other and into the roller wheels A and A'; either built
up with the machine, or attached thereto upon a separate casting or fixture, sub-
stantially as described and illustrated.
