Improvements in Tramway and other Wheels.
WILLIAM TOZER, Merchant, Botolph House, Eastcheap, London, E.C., in
the County of Middlesex, FREDERIC BARRY STANTON, Engineer, Mansion
House Chambers, 11, Queen Victoria Street, E.C., London, in the County of
Middlesex, do hereby declare the nature of this invention to be as follows:-
Our invention relates to tramway and other wheels and. is designed to improve
their construction and thereby impart to them strength efficiency durability lightness
and at the same time to facilitate the removal of the tyre and its replacement. With
a view of gaining strength and reducing weight we propose to form one or more
discs of thin steel or other suitable material with radial corrugations in such a
manner as to withstand great pressure. On the centre of these discs we weld or
otherwise fix a boss or nave in such form that the opposite disc may be secured
thereto by bolts rivets catches or other means.
At the outer edges we flange the corrugated disc so as to form a continuous ring
fastening which we force into grooves in the inner and outer sides of the tyre so that
should a tyre burst, the broken part is held firmly in place.
When it is desired to replace a worn tyre one of the discs is removed which
allows of the tyre being taken away and a new one inserted the disc is then replaced,
bolted or otherwise fastened up and the wheel is ready for use.
Dated this 19th day of May 1890.

COMPLETE SPECIFICATION.
Improvements in Tramway and other Wheels.
WILLIAM TOZER, Merchant, Botolph House, Eastcheap, London, E.C., in
the County of Middlesex, and FREDERIC BARRY STANTON, Engineer, Mansion
House Chambers, 11, Queen Victoria Street, London, E.C., in the same County,
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:-
Our invention relates to tramway and other wheels and is designed to improve
their construction and thereby impart to them strength efficiency durability and
lightness and at the same time to facilitate the removal of the tyre and its replace-
ment with a view of gaining strength and reducing weight we propose to form one
or more discs of thin steel or other suitable material corrugated in such a manner
as to withstand great pressure.
On the centre of these discs we weld or otherwise fix
a boss or nave in such form that the opposite disc may be secured thereto by bolts,
rivets, catches or other means. At the outer edges we flange or otherwise arrange
the corrugated disc or discs so as to form a continuous ring fastening which we force
into grooves in the inner and outer sides of the tyre so that should a tyre burst the
broken part is held firmly in place; the accompanying drawing shews various
methods of securing the disc to the tyre and nave and any suitable method may
be adopted.
Fig. A shews half section of wheel having two dished corrugated discs f, flanged
at outside edges to fit into recesses in tyre a and bolted (as at a Fig. A¹) one disc

page_text: left plain near the centre 6 the other having a boss c welded thereto the two discs
being bolted together with bolts d
Fig. B shews half section of wheel having two corrugated discs g flanged at
outside edges to fit into recesses in tyre h and bolted (as at a' in Fig. A¹) the
corrugations deepening towards the centre where the discs are bolted to a boss j
with bolts k.
Fig. C shews half section of wheel having corrugated discs / bolted through out-
side edges and tongue of tyre m with bolts n and also bolted near the centre to
boss p with bolts 1.
Fig. D shews half section of wheel with a combination of discs shewn in
Figs. B & C.
Fig. A' is a quarter elevation of wheel shewn in Fig. A. flanging as at ≈ shews
another method of stiffening the discs.
Fig. C is a quarter elevation of wheel shewn in Fig. C.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
A wheel centre composed of one or more discs made of mild steel or other
suitable material, pressed, stamped or forged into shape being indented, corrugated
or flanged radially to the centre of wheel as and for the purpose specified and fixed
to the nave and tyre in any convenient and suitable manner.
Dated this the Eleventh day of March 1891.
