An Improved Axle Bearing specially adapted for Subsidiary Wheels
of Cycles and other Wheeled Vehicles.
I, WILLIAM SHONE, Upton Park, Chester, Assistant Overseer of Chester, do
hereby declare the nature of this invention to be as follows:-
In my invention each wheel has an independent axle working in a slot of a
box. In this axle box is a spring which acts upon the axle. The spring is
adjustable by a screw preferably outside the box. Each box is attached directly
or indirectly to the frame of the vehicle.
This is specially adapted for use with two subsidiary wheels of bicycles outside
the treadles. These serve as a support to the cycle and also assist learners. Each
axle box is attached to a forked support which is secured to the frame of the
cycle.
I do not however limit myself to this application.

I, WILLIAM SHONE, Upton Park, Chester, Assistant Overseer of Ch
hereby declare the nature of this invention and in what manner th
be performed, to be particularly described and ascertained in and by the io.i w
statement—
In my invention subsidiary wheels are provided the axles of which work in
a slot of a box. In this axle box is a spring which acts upon the axle. This
spring is adjustable by a screw. The invention is specially applicable for sub-
sidiary wheels of cycles outside the treadles, which serve as supports to the cycle.
To show how my invention is performed I furnish drawings in which the same
parts are marked by the same letters.
Fig. 1 is a longitudinal section of the adjustable axle bearing. The axle A
works inside slot B of box C. The axle bearing box 1) rests on block E whielt
is secured by nut and screw F in any desired position so as to prevent axle A
descending too far. The spring G is fastened below to axle bearing box D and
above to block H, which by means of nut and screw J puts the spring G into the
required tension.

page_text: Fig. 2, is a view of self adjusting axle attached to cycle frame so as to form a
support. K is back fork of cycle frame to which is secured on each side bearing
arm L. Two vertical rods M on each side of frame K are attached to bearing
arm L. Up and down these rods M move the axle boxes C. The rods M pass
through holes in extensions or appendages of boxes (not interfering with the adjust-
ing spring arrangements in said boxes. The axle A carries the subsidiary wheel N.
One axle box Con each side of frame K has attached to it a tubular rod 0.
Inside O works the screw rod P, which is attached to bearing arm L at T. A
spring Q is fastened to tubular rod O at R and compressed by nut S screwed
on to rod P so as to make the connexion between C and L flexible. The spring Q
can be enclosed in a box if desired. This arrangement is repeated on the other
side of the frame K.
When the cycle is inclined one way or the other, the distance between T and
the ground is diminished, and, consequently, one subsidiary wheel N touches the
ground and supports the cycle, the adjusting apparatus coming into play auto-
matically.
In a simpler but less perfect form the connection between box C and bearing
arm L may be one continuous solid or tubular rod.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed, I declare that what I claim is:
-
1. An adjustable axle bearing in which on one side the bearing box is limited
in its movement and on the other side is acted upon by a spring whose tension
can be altered at will.
2. The arrangement shown in Fig. 2, where the adjustable apparatus comes
into play automatically, substantially as described.
