of Washing, Wringing, and Mangling Machines.
We, HEBDEN COLBURN of Oakworth near Keighley in the County of York,
Foreman, and JONAS OGDEN of Aireworth Street, Keighley aforesaid, mechanic do
hereby declare the nature of this invention to be as follows, that is to say :-
It consists of an improved device applicable to weighted-lever and other machines
for washing wringing and mangling whereby the rollers thereof, may be relieved of
the pressure imparted to them through or by their well known weighted levers when-
ever desired with the advantage of saving said rollers from the rapid deterioration
at present experienced.
To attain this an eccentric is mounted in a suitable position on the framework of
the machine beneath the above named weighted levers, an appropriate handle being
attached to said eccentric so that by this handle the eccentric may be inade to rotate
on its axis and raise the levers. A hollow or recess being made on the outer edge
or periphery of said eccentric so that when it has moved and lifted the levers to their
highest position, said levers, by resting on said hollow part, will be retained in this
position.
Instead of the eccentric being employed as above set forth, two eccentrics may be
used, one being mounted on the end frame on one side of machine and the other on
the end frame on the other side thereof, in suitable proximity with the outer ends of
the upper roller. Each of these eccentrics being arranged by suitable connecting
parts, so that when rotated they receive the whole of the pressure of the weighted
levers through the well known upright connecting or pressure rods; in this manner
relieving said rollers of same. And by a projection being formed on the periphery
of each of said eccentrics, or by the "dies" in connection with the top rollers being

page_text: formed to encircle the axle shafts of same, whenever said eccentrics are moved to
receive the pressure, as above described, the top roller will be lifted clear of the bottom
one, an object very much desired for their preservation.
Again the two last named eccentrics may be substituted by two suitably shaped
locking levers, mounted in similar positions to the end frames of the machine.
The two last named devices are also applicable to any of the usual well known kinds
of top or bottom spring machines, as will be readily understood.

We, HEBDEN COLBURN of Oakworth near Keighley in the County of York,
Foreman, and JONAS OGDEN of Aireworth Street Keighley aforesaid, mechanic 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 is to say:
:-
It consists of an improved device applicable for weighted-lever and other machines
used for washing, wringing and mangling purposes, by the employment of which
the rollers thereof may be relieved of the pressure imparted to them through or by
their well known weighted levers whenever desired, with the advantage of saving said
rollers from the rapid deterioration at present experienced.
In order that our said invention may be more readily understood we have hereunto
appended sheets of drawings illustrative thereof to which, by figures and letters,
reference is made in the following description.
Fig. 1 is a front elevation and fig. 2 a sectional end view of a sufficient portion of
a machine to illustrate the application of our improvements. Figs. 3 and 4 are detail
drawings enlarged scale of parts hereinafter referred to. Figs. 5 and 6 are portions
of similar views to figs. 1 and 2 respectively and illustrate another arrangement of
our improvements.
The object of this invention is attained by mounting an eccentric a upon the
framework of the machine, the same being mounted beneath the weighted levers c c¹
so that by the handle it (said eccentric a) may be rotated on its axis and made to
raise said levers c c'. A hollow or recess e is made on the outer edge or periphery of
the eccentric a so that when it has moved and lifted the levers c c to their highest.
position, they will be retained in this position by resting on said hollow part e.
Instead of the eccentric a being employed as above set forth, two eccentrics may
be used, one being mounted on the end frame b on one side of the machine and the
other on the end frame on the other side thereof, in suitable proximity with the outer
ends of the top roller g. Each of these eccentrics f is arranged to operate a lever h,
which is pivoted at to the end frame b, so that when each of said eccentrics f is
rotated they raise said lever as also said roller g, in this manner receiving the whole
of the pressure of the weighted levers.
Or again the eccentrics may be made to operate the upright rods kk by being
mounted upon the frame-work & somewhat as is shewn by broken lines fig. 2.
In order to obviate the rebounding of the levers e, as the roller is lifted by
articles passing between it and the roller gas when in use, we insert the spiral
spring m to form the joining piece between the bottom and the top parts of the
rods the same having the compensating effect easily understood.

In any or all of the arrangements as above described it will be seen that when-
ever the eccentrics a or fare moved or rotated to receive the pressure, the top roller
is lifted clear of the bottom roller g' an object which is very essential for their more
effectual preservation.
The device illustrated by figs. 5 and 6 is also applicable for use in connection with
any of the well known kinds of top or bottom spring machines as will be readily
understood.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :
1. The eccentric a with its handle d, the levers c c¹ the rods k k¹, and the roliers g g'
in combination, the same being constructed and arranged to operate in the manner
and for the purposes substantially as herein specified.
2. The eccentric a with its handle d, the levers c¹ the rodsk k¹, the springs m,
and the rollers g g in combination, the same being constructed and arranged to
operate in the manner and for the purposes substantially as herein specified.
3. The eccentric f, the lever h, and the rollers g g in combination, the same
being constructed and arranged to operate in the manner and for the purposes
substantially as herein specified.
