PROVISIONAL SPECIFICATION.
Improved Castor for Use in connection with Wringing and like
Machines.
We, CLAPHAM HOLMES, ISRAEL PEARSON and NATHAN MIDGLEY all of
Royal Iron Works, Keighley in the County of York, Machine Makers, do hereby
declare the nature of this invention to be as follows, that is to say :-
It relates to improvements in the formation and construction of castors for
use in connection with wringing and like machines whereby they are made
to be thoroughly efficient for their purpose while their cost of production does
not greatly add to that of the machines to which they are applied.
In accordance with our said invention we mount the usual bowl or runner in
bearings that form a disc at the part where they join together. These bearings
and disc are formed of cast metal and in the process of casting are poured into the
mould to run around their axial pin which is placed in said mould, the sudden
cooling or chilling of which cast metal, sufficiently relieves it from said pin so that
on its withdrawal from the mould it will loosely revolve on same.
To take over the axial pin and fit over this disc is another disc also of cast metal,
and in this disc an annular groove is formed concentrically with its axial pin so that
suitably formed antifriction rollers may be placed and retained therein when the
two discs are brought together.
The bowl or runner, its bearings, the two discs with the antifriction rollers placed
between them, and the axial pin are then taken and placed in the mould in which
the wringing or like machine's end frame is to be formed, by which means when the
casting of such end frame is produced the castor forms an undetachable part of its,
its said axial pin and upper disc forming a homogeneous joint with the end-frame.
Or instead of this method being followed in forming the joint a suitable part may be
made so that the castor may be bolted to the end frame, however the method first
before described is preferably employed.

COMPLETE SPECIFICATION.
Improved Castor for Use in connection with Wringing and like
Machines.
We, CLAPHAM HOLMES, ISRAEL PEARSON and NATHAN MIDGLEY all of
Royal 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

page_text: be performed, to be particularly described and ascertained in and by the following
statement, that is to say :-
It relates to improvements in the formation and construction of castors for use
in connection with wringing and like machines whereby they are made to be
thoroughly efficient for their purpose while their cost of production does not greatly
add to that of the machines to which they are applied.
In the accompanying sheet of drawings
Fig. 1 is end elevation of a portion of a wringing or mangling machine showing
the application of our improved parts.
Fig. 2 is part sectional side elevation enlarged scale, illustrative of our improved
castor as detached or cut away from the machine.
Fig. 3 is end elevation of parts shown by Fig. 2.
Fig. 4 is a sectional top view on line A B of parts shown by Fig. 2.
Fig. 5 is part sectional side elevation similar to Fig. 2 but shows a modification
in the formation of certain of the parts.
In accordance with our invention we mount the bowl or runner a (having a
peripheral form as shown by Figs. 1, 3, and 4, or the usual form of bowl may be
made use of) in the bearings that form a disc c at the part approaching the
framework d where another disc f is formed.
These bearings and disc c are formed of cast metal and in the process of casting 2
are poured into the mould to run around their axial pin 9 (see Fig. 5) which is of
wrought iron and is placed in said mould prior to the pouring in of the molten
metal, the sudden cooling or chilling of said molten metal sufficiently relieves it
from said pin 9 (in a manner extensively followed by manufacturers of the class of
machine to which this invention applies) so that on its withdrawal from the mould
it (the disc c now formed) will loosely revolve on same, its head g¹ retaining it in
position.
Or the pin may be fixed within the framework d and discf while it passes
loosely through the disc b which is retained thereon by the pin has shown by
Figs. 1, 2 and 3, in which case the annular groove k is made in the disc e instead of 3
being in the disc f as shown by Fig. 5.
The disc is also formed concentrically with the pin 9 or 93 and has an annular
groove k formed therein (see Fig. 5) when same is not formed in the disc c as
above described, in which antifriction rollers m are placed to facilitate the
movements of the disc c about its said pin g.
When the formation of bearings, discs and pin shown by Fig. 5 is followed, all
these parts are preferably formed by being cast together as above described, the
antifriction bowls being placed in position and the whole then placed in the mould
where the remaining portion of molten metal is run to form the whole end frame d
or instead of the castor part being thus integrally formed with the end frame it
may be bolted or otherwise fixed thereto as may be desired.
Provided it is found desirable to render one or other of the castors inoperative
as such, for the purpose of anchoring the machine, a catch piece s hinged at t to the
framework d may be employed for entering the opening between (or spanning) the
bifurcations of the bearings b as shown by Fig. 2 and in broken lines Fig. 3, such
catch-piece being hinged so that it may be turned out of position when not
required as shown by Fig. 1. Or other catch pieces or locking pins may be
employed, but for cheapness we preferably make use of the one shown.
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. The combination of castors formed as described with the framework of a
washing, wringing or mangling machine substantially as specified.
2. The combination in a washing, wringing or mangling machine of the parts
described substantially as herein specified.

herein set forth.
