PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Castor Bowls.
1, JOHN HARRINGTON, of Claremont, West Street, Ryde, in the Isle of Wight,
Manufacturer, do hereby declare the nature of this invention to be as follows:
The invention relates to improvements in the manufacture of castor bowls
whereby cheapness of construction and other advantages are obtained.
According to my invention I form castor bowls by building them up of a central
metal bush or bearing and two interfitting metal cups forming the cheeks and
running edge or periphery. The central bush or bearing is formed with a reduced
part at each end thereof, and the cups are formed with central holes to fit tightly
such reduced parts, whilst the rim of one of the cups is made to fit tightly within
the rim of the other so as to require some amount of power to force them together,
after which the ends of the central busb or bearing are burred over on to the
cheeks of the cups and, if desired, the larger rim is burred over the junction of
the smaller rim with its cheek. The two cups fit together like a box and lid.

Improvements in the Manufacture of Castor Bowls.
I, JOHN HARRINGTON, of Claremont, West Street, Ryde, in the Isle of Wight,
Manufacturer, 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 :-
The invention relates to improvements in the manufacture of castor bowls
whereby cheapness of construction and other advantages are obtained.
According to my invention I form castor bowls by building them up of a central
metal bush or bearing and two interfitting metal cups forming the cheeks and
running edge or periphery. The central bush or bearing is formed with a reduced
part at each end thereof, and the cups are formed with central holes to fit tightly
such reduced parts, whilst the rim of one of the cups is made to fit tightly within
the rim of the other so as to require some amount of power to force them together,
after which the ends of the central bush or bearing are burred over onto the cheeks
of the cups and, if desired, the larger rim is burred over the junction of the
smaller rim with its cheek. The two cups fit tightly like a box and lid.
My invention is illustrated in the accompanying drawings in which:-
Fig. 1 is an elevation of my improved castor bowl as seen from the outer side
thereof.
Fig. 2 is a similar view to Fig. 1 but seen from the inner side.
Fig. 3 is a cross section, Fig. 4 shows the central bush or bearing, and Figures 5
and 6 show respectively the outer and the inner flanged side cheeks of my improved
aston homl

page_text: a is the central bush or bearing which may be made solid as shown at Fig. 4 or
it may be made of two unequal lengths of drawn tubing forced the one tightly into
the other; it is formed as shown with a reduced part a¹ at each end thereof.
b. c are side cheeks having central holes therein fitting tightly the reduced ends a
of the central bush or bearing a and the said cheeks are formed respectively with
cylindrical flanges d. e of slightly different diameters. The various parts are
placed in proper relative position and forced together, when the cylindrical flange d
will be forced into the flange e and the central parts of the cheeks b. c over the
reduced ends a¹ of the central bush or bearing a; the ends of this latter are then
burred or rivetted over the side cheeks and the edge of the flange e is preferably
spun or burred over the junction of the flange d with its side cheek b. The outer
flange e thus forms the running surface.
I would here remark that the use of a central bush or bearing with reduced ends
and of side cheeks with central holes forced over the reduced ends of such central
bush or bearing separately considered form no part of my present invention as
such parts were shown,and described in the Specification of Letters Patent granted
to me No. 16408 of the year 1895.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A castor bowl constructed substantially as herein shown and described.
2. In a castor bowl the combination of a central bush or bearing with reduced
ends, centrally perforated side cheeks fitting tightly such reduced ends and
cylindrical flanges of slightly different diameters connected with such side cheeks
fitting tightly the one over the other, such parts being firmly secured together by
rivetting or burring over the reduced ends of the central bush or bearing and the
outer edge of the outer cylindrical flange, substantially as herein shown and
described.
3. In a castor bowl built up as hercin described, a running ring composed of two
cylindrical flanges, of the side cheeks forced the one into the other, substantially
as herein shown and described.
