An improved ball bearing axle, having ball bearings at both ends of bush, the
bush is made of metal and recessed at both ends, into each recess a hardened steel
cup is fitted with raised lip, the balls going in those cups, and being held in position
by detachable, steel washers, so, that the bush can be removed from axle without
the balls becoming displaced. The balls revolve in detachable steel cones, one on

GEO. A. STRONG.
An Improvement in Ball Bearing Axle Boxes, suitable for Road
Vehicles and the like.
I, GEORGE ALBERT STRONG, of 8 Greek Street, Dublin, Ireland, Patent
Carriage Axle Maker, 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 has reference to an improved ball bearing axle provided with ball
bearings at both ends of bush whereby friction is reduced to a minimum and
a perfectly smooth rolling contact obtained.
The bush is made of metal recessed at both ends, and into each recess is shrunk
a hardened steel cup provided with a raised lip on its inner side.
The balls are carried in these cups and are held in position by detachable steel
washers so that the bush can readily be removed from the axle without the balls
becoming displaced.
The balls revolve on detachable steel cones-one on each end of axle-one cone
being screwed or driven on arm, and held in position by a pin; the other cone being
an adjustable screwed cone held in position by a lock nut and pin.
An ordinary brass oil cap screwed into the bush in front in the usual manner-
completes the improved axle bush.
In order that my said invention may be more readily understood, and carried into
practice, I will describe the accompanying drawings, in which
Fig. 1, represents a longitudinal view of the improved bush and broken portion
of axle. Fig. 2, is a section of same; and
Fig. 3, is an end view of the bush shewing the balls in position.
A, is the axle which is slightly squared at its outer end for the purpose presently
described. B, is the bush; b, b, the hardened steel cups shrunk into its recesses at.

page_text: both ends. In these cups the balls c, are placed-a sufficient number being used to
occupy the circunference complete. d, d, are the detachable steel washers which
are shrunk or screwed into position and retain the balls in the cups.
e, e¹ are the
detachable steel cones, the inner cone e¹ being driven on the arm and secured by a
pin, while the outer cone e, is.adjustable and is screwed on the axle. This cone is
held in position by a lock nut between which and the cone is inserted a "D,"
washer g. for the purpose of enabling the lock nut to be screwed home tight without
affecting the cone.
The lock nut is secured by a pin h.
k, is the brass oil cap screwed home against the leather washer l.
From this description it will be seen that the bush may be readily removed from
the axle without disturbing the balls which will be at once recognised a most
convenient and useful arrangement.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I would have it understood
that what I claim is :-
First. In the construction of axle bushes for road vehicles, and the like, the use
and application of ball bearings arranged and operating in the manner substantially
as herein specified.
Second. In axle bushes, the combination formed by the steel cups b, b; balls c;
washers d, d, cones e, e', and lock nut f, all arranged, constructed, and operating in
the manner substantially as herein described and set forth.
