PROVISIONAL SPECIFICATION.
Improvements in Securing Metal Wheels to their Axles.
I, JOHN WILLIM HALL, of Ivy House, Bilston, Staffordshire, Engineer, do
hereby declare the nature of this invention to be as follows:-
This invention consists in the hereindescribed improvements in securing metal
wheels to their axles and this invention is applicable inore particularly to the cast
steel wheels and axles of colliery tramway waggons but the said invention can be
similarly applied to permanently fixing other metal wheels on their axles.
By my invention the cost of fixing the said wheels on their axle is very consider-
ably reduced and it is impossible for the wheels when once fixed to ever become
loose.
For the purposes of this invention I make the axle perfectly true and if desired
I shoulder down the ends thereof on which the wheels fit; the eye of each wheel is
made perfectly true with the rim and a good fit on the axle. When the wheels
have or one of them has been forced or otherwise placed in position on the axle,
each end of the latter and the outside face of the boss of the corresponding wheel are
by any convenient means heated to a welding heat and then welded together thus
making it quite impossible for the wheels to become loose.
The eye of the wheel can very readily be made true with the wheel rim by
employing a press furnished with a punch or drift of the proper size which latter is
passed through the eye of the wheel while the wheel is being held by a self centering
chuck or by other means.

COMPLETE SPECIFICATION.
Improvements in Securing Metal Wheels to their Axles.
1, JOHN WILLIM HALL, of 1vy House, Bilston, Staffordshire, Engineer, 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 consists in the herein-described improvements in securing metal
wheels to their axles and this invention applicable more particularly to the cast
steel wheels and axles of colliery tramway waggons but the said invention can be
similarly applied to permanently fixing other metal wheels on their axles providing
such wheels and axles are made of wrought iron or steel which can be welded.
By my invention the cost of fixing the said wheels on their axle is very consider-
ably reduced and it is impossible for the wheels when once fixed to ever become
loose.
For the purposes of this invention I make the axle perfectly true by turning in a
lathe or by other well known means and if desired I shoulder down the ends of the
axle on which the wheels fit; the eye of each wheel is by boring or other means made
perfectly true with the rim and a good fit on the axle. When the wheels have or
one of them has been forced by hydraulic or other pressure or otherwise placed in
position on the axle, as by being heated and shrunk thercon, each end of the latter
and the outside face of the boss of the corresponding wheel are by any convenient
means heated to a welding heat and then welded together by hammering thus

page_text: making it quite impossible for the wheels to become loose. The weld extends along
the axle for about half an inch from the face of the wheel.
The eye of the wheel can very readily be made true with the wheel rim by boring
or by employing a hydraulic or other press furnished with a punch or drift of the
proper size corresponding with the eye of the wheel which punch or drift is forced
through the eye of the wheel while the wheel is hot and is being held by a self
centering chuck or by other means.
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
claim is:
1. Securing cast steel or other ductile metal wheels to their axles by fitting the
wheels tightly thereon and then heating and welding together the ends of the axle
and the corresponding bosses of the wheels, substantially as herein set forth.
2. A steel or other ductile metal axle for a colliery tramway waggon or for other
like purposes having a wheel fixed on each end by the axle and wheels being welded
together as herein set forth.
