An Improved Device for Use in Domestic Wringing and
Mangling Machines.
We, ROBERT NEWSHOLME SMITII and SIEM PAGET, Engineers, and SAMUEL
HERBERT HORSEMAN, Mechanic, all of the Crown Works, Keighley, in the County
of York, 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 for an improved device for use in domestic wringing and
mangling machines has for its object to provide means for facilitating the rais-
ing and supporting of the upper roller of the machine out of contact with the
lower roller when the machine is not in use and thereby to preserve the roller
from the deteriorating effects arising from the tendency of water to lodge
between the parts in contact when the rollers rest one upon the other; and con-
sists of a casting formed at one end with a cam or inclined surface, at its other
end with a segmental or other suitable bearing, and at one side with a projec
tion or handle. The casting is supported on the end of the lower roller axle
in the end frame of the machine and normally rests therein with its cam surface
just below and out of contact with the axle of the upper roller, and when it is
desired to raise the upper roller the casting is rocked into such a position that
the lower part of its cam surface is brought into contact with the underside
of the upper roller axle whereupon the cam surface forms a bearing for the
upper roller axle so that the axle on being rotated mounts the incline or cam
and raises its roller.
In the accompanying sheet of illustrative drawings Figs. 1 and 2 are end
elevations of mangling and wringing machines provided with a roller raising
device constructed according to this invention. Fig. 3 is a similar view showing
the position of the raising device when in use. Fig. 4 is a front elevation and
Fig. 5 a sectional plan showing the position of the device in the end frame of
a machine. Figs. 6 and 7 are detached views showing the device in elevation
and sectional plan.
The roller raising device consists of the casting a mounted between the upper
and lower roller axles, formed at its upper part with a cam or incline b and
at its lower end with the bearing c which rests on the axle d of the lower
roller e.
The casting a is suitably shaped for insertion between the sides of
the end frame f of the machine and is provided at one side with a projection g
by means of which it is rocked on the axle d into or out of contact with the
axle h of the upper roller i.
The operation of the device will be readily seen: on pressing on the projec-
tion the front of the cam surface is brought in contact with the axle h which
in being rotated in the direction of the arrow rolls up the incline into the posi-
tion shown in Fig. 3 drawing the cam forward for the purpose and is thereby
raised and with it the roller i out of contact with roller e.

page_text: Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed, we declare that what
we claim is;-
-
1. In mangling and wringing machines the improved device for raising the
upper roller out of contact with the lower roller consisting of a casting adapted
to be interposed in the end frame of the machine between the upper and lower
roller axles and formed with an incline or cam substantially as described.
2. The improved device for use in domestic wringing and mangling machines
substantially as described with reference to the drawings.
