PROVISIONAL SPECIFICATION.
Improvements in the Axles of Road Vehicles and their Bearings.
I WILLIAM WILSON HULL of Gold Street Northampton in the County of
Northampton Coach Builder do hereby declare the nature of my said invention to
be as follows:-
These improvements relate more particularly to the axles and bearings of carts and
carriages and are intended to lessen the friction so as to afford easier draught and
also a ready means for adjusting the bearings such bearings being adapted to the use
of balls and the like and are likewise intended to provide a more effective means of
lubrication.
In carrying out my invention I preferably use a solid faggoted axle carrying a
shoulder or case hardened collar against which the balls revolve with an extension
beyond this which is screwed at its extremity to receive the "Collett" washer and
nut hereinafter described.
In the inner face of the hub of the wheel I let in a box of steel or other metal to
carry the balls or the like and having its inner extremity internally screwed or
threaded to receive the correspondingly screwed or threaded end of a steel or other
tube surrounding the extremity of the axle the opposite end of this tube is also
screwed or threaded and on this is fitted the opposite box let into the outer face of
the hub. This box is internally screwed or threaded to engage with the corresponding
screwed or threaded end of a cap which secures the whole arrangement and the parts
hereinafter described.
On the screwed end of the axle I provide an adjustable "Collet" by means of
which the balls are held in position and more or less freedom for the same may be
obtained. This "Collet" is kept in position by means of a washer and nut in which
is a hole for a lynch pin or cottar.
The oil or other lubricant is held in the boxes and the top of the axle is chased the
whole length of the arm along which the oil or the like may run and being confined
to the boxes does not so readily escape over the wheel.

COMPLETE SPECIFICATION.
Improvements in the Axles of Road Vehicles and their Bearings.
I WILLIAM WILSON HULL of Gold Street Northampton County of Northampton
Coach Builder 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 :-
These improvements relate more particularly to the axles and bearings of carts
and carriages and are intended to lessen the friction so as to afford easier draught
and also a ready means for adjusting the bearings, such bearings being adapted to
the use of balls and the like and are likewise intended to provide a more effective
means of lubrication.
In carrying out my invention I preferably use a solid faggotted axle carrying a
shoulder or case hardened collar against which the balls revolve with an extension
beyond this which is screwed at its extremity to receive the "collets" washer and
nut hereafter described. In the inner face of the hub of the wheel I let in a box of
steel or other metal to carry the balls and the like and having its inner extremity

page_text: internally screwed or threaded to receive the correspondingly screwed or threaded
end of a steel or other tube surrounding the extremity of the axle, the opposite
end of this tube is also screwed or threaded to and on this is fitted the opposite box
let into the outer face of the hub.
This box is internally screwed or threaded to engage with the corresponding
screwed or threaded end of a cap which secures the whole arrangement and the parts
hereafter described.
On the screwed end of the axle 1 provide an adjustable "collet" by means of
which the balls are held in position.
Referring to the accompanying drawing A is the axle and A¹ the extremity thereof
shewn in section as are also the other parts in connection therewith except a portion
of the surrounding tube and B B are the boxes let into the hubs of the wheels in
which run the balls or rollers C, C, C, C.
D is the tube surrounding the axle A¹ and with the boxes which it is intended to
connect and adjust let into the hub of the wheel. The inner extremities of these
boxes are tapped at b, b to receive the screwed or threaded ends of the tube D).
The onter extremity of one box is also tapped to engage with the correspondingly
screwed end of the cap E. The collet F is adjustable on the screwed or threaded
end of the axle A' and is grooved so as to provide a race for the ball or other
bearings and is kept in position by a washer G and nut H which may be further
secured by a lynch pin or cotter if desirable.
The cap E encloses and secures the adjustable parts and it will be seen that by
means of the tube D I am able to adjust the whole of the bearings without removing
the wheel.
Oil or other lubricant may be introduced into the boxes and I prefer to chase the
whole length of the top of the arm A³ so that such may pass freely to the bearings
whilst the cap E prevents it escaping over the wheel.
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. In the axles of road vehicles and the like the shouldered and screwed extremity,
substantially as herein described and illustrated in the accompanying drawing.
2. In the hubs of wheels of road vehicles and the like the use of a tube such as D
connecting the boxes thereof as and for the purposes described.
3. For use in road vehicles and the like arrangement of axle extremities and
bearings substantially as herein described and as illustrated in the accompanying
drawing.
