PROVISIONAL SPECIFICATION.
Improved Axles for Railway Carriages, Waggons, and similar
Vehicles.
I STEPHEN PETTIT of Church Road, Norbiton in the County of Surrey,
Gentleman do hereby declare the nature of this invention to be as follows:-
This invention relates to improved axles for railway carriages, waggons and
other vehicles.
According to this invention I form the axles in two parts.
Into a tube I insert either a hollow or solid axle, so as to revolve freely in the
first mentioned tube; on to one end of this tube I fix one of the wheels; and on
to the end of the hollow or solid axle protruding from the other end of the tube
I fix the other wheel. By this means each wheel will run independently of the
other wheel.
I provide suitable means to prevent this compound axle from coming apart.
Dated this Seventh day of February 1895.

Vehicles.
I STEPHEN PETTIT of Church Street and Church Road, Kingston-on-Thames
Tailor 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 :-
I take a steel or other tube a (see the accompanying drawing) of the required
length strength and size upon one end of which I fix a wheel of the required
character.
I then take a second axle c of the required length and of such diameter as will
pass freely and without "play" inside the axle a, and on the end of c, I fix the
other wheel d. The second axle e I pass through the tubular one a. The end of
the axle e should protrude through the end of a in such manner and to such extent
as will allow of a cap or nut e being screwed thereon, or so that a pin or the like
may be employed to hold the axle e securely within a.
.
The compound axle thus formed is placed in suitable bearings which may be
made in two parts in the ordinary manner and fixed either to the springs g or
directly to the framework of the vehicle h. In order to keep the respective axles
in position, the tubular one a may be of such length as to butt against one of the
bearings as at 1, a collar i being attached to the axle c so as to be in contact with
the other side of the bearing as at f³. As an alternative method of keeping the
axles in position, a may be passed through both bearings and collars affixed to it,
one being outside each bearing f and consequently between the respective bearings
and wheels.
By the above arrangement the wheels will be able to revolve round co-incident
axes but independently of each other.

page_text: The bearings may be put outside instead of inside the wheels if desired.
I do not confine myself to the shapes, relative proportions or disposition of
parts described or shown as they may be varied as occasion may require without
departing from the spirit of my invention.
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 compound axle for vehicles and consisting of a tubular axle having one
wheel attached to it, and within which is free to revolve another axle bearing the
other wheel, the whole provided for and operating substantially as described in
the above Specification and exemplified in the accompanying drawing.
2. The combination of parts together forming an improved axle for railway
carriages, waggons, and similar vehicles, substantially as described in the above
Specification & exemplified in the accompanying drawing.
