PROVISIONAL SPECIFICATION.
Improvements in Wheels for Railway and like Vehicles.
I, JOHN BAKER of Frederick Street Rotherham in the County of York Wood
Turner, do hereby declare the nature of this invention to be as follows :-
This invention relates to wheels for railway and like vehicles and has for its
object to construct the same in a strong substantial and economical manner to
attain which I form on the inner periphery of the tyre an annular projection having
a circumferential groove on each side thereof.
The inner or centre part of my improved wheel I form of two discs or plates of
steel or other suitable metal each said disc or plate having a centre or boss part
arranged one to fit into or over the other and an annular tongue or projection on
their circumferences to fit into the grooves aforesaid of the tyre. These two plates
are preferably forced one towards the other and simultaneously into the tyre of the
wheel by hydraulic pressure and subsequently they may be bolted or rivetted to
the grooved projection on the tyre.
The plates or discs aforesaid may receive a packing or filling in of wood or
other substance between and they may be belled out or bevelled or straight as
preferred.
It will be obvious that although I have described a special form of tyre for my
improved plates or discs they may where desired be modified so as to suit
any ordinary form of tyre in which case the two discs may be cast in one piece
with wood or other suitable substance filling up the hollow part thereof.
Dated this 23rd day of August 1894.

Improvements in Wheels for Railway and like Vehicles.
I, JOHN BAKER of Frederick Street Rotherham in the County of York, Wood
Turner, 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 relates to wheels for railway and like vehicles and has for its
object to construct the same in a strong substantial and economical manner, to attain
which arrange and construct my improved wheels substantially as set forth in the
accompanying drawing in which
Figs. 1, 2 and 3 are elevations partly in cross section of my improvements
applied to my improved form of tyre and Figs. 4 and 5 are elevations of portions
of my improvements applied to an ordinary form of tyre.
Fig. 6 is a cross sectional elevation of part and Fig. 7 a longitudinal sectional
elevation taken on line a a of said Fig. 7 of a modification of the boss part of my
improved wheel.
of
Fig. 8 is a cross sectional elevation of a part of the boss of a further modification
me improved whool

page_text: Referring to Figs. 1, 2 and 3, I form the inner periphery of the tyre A
with an annular projection at having a circumferential groove a² on each side
thereof.
The inner or centre part of my improved wheel is formed of two discs or plates B
having a centre or boss part b¹ arranged so that the said boss part 6¹ of one plate B
fits into or over the boss part 6 of the opposite plate B, and each plate B is formed
with an annular tongue or projection 62 upon its circumference in order to fit into
the grooves a² of the tyre A.
The plates B may be forced one towards the other and simultaneously into the
tyre A of my improved wheel by hydraulic pressure and subsequently they may be
bolted together or rivetted to the annular projection a¹ by the bolts or rivets d³ in
which latter case flanges a³ are formed upon said projection a¹ for the bolts or rivets
to bear in as shown at Fig. 1.
Referring to Fig. 2. the plates B are built up as follows:
The annular tongue or projection 62 is rolled in the form of a flanged ring and
the boss b¹ is forged with a flange on it, the rest of the plate being welded to the
flange ring aforesaid and the flanged boss; and subsequently the two plates B are
welded together at their bosses simultaneously with their being forced or pressed
into the tyre A.
Referring to Fig. 3 the space between the plates B has a filling in of wood or
other suitable substance C in which arrangement the projection a¹ is formed with
only one flange a³ in order to enable the wood or other substance C to be placed
between and to fill up the space between the plates B.
The plates B may be belled out as shown at Fig. 1. or tapered as shown at
Fig. 4. or straight as shown in the remaining figures.
It will be obvious that where so desired my improved plates or discs B
may be modified so as to suit any ordinary form of tyre as shown at Figs. 4
and 5.
In order to more securely hold the plates B together I in some cases employ
a pronged ring or collar D (preferably composed of cast steel) the prongs d of
which extend in a radial direction and have a number of holes in them. "When
welding the two bosses b¹ and plates B together a portion of the iron from
either boss is forced into the holes of the prongs d' and thereby the plates B
become more securely welded or held together and form one hollow centre part of
my improved wheel.
In Fig. 8. the ring or collar D is formed with an annular indent or number of
indents d² and when the boss parts are welded together a portion of the iron of
each boss part squeezes into the said indent or indents and so fixes the plates B
together.
When using ordinary tyres it will be understood that for a cheaply constructed
wheel the two plates B may be cast in one and have wood or other light material
to fill up the hollow part thereof, and in some cases the two plates B may be
welded close together or nearly so as shown at Fig. 5.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :
1. In wheels for railway and like vehicles the combination of two metallic
plates B having tongues 62 with a tyre having a grooved or grooved and flanged
projection a substantially as described and illustrated.
2. In wheels for railway and like vehicles the combination of two plates B
welded or otherwise secured at their bosses 6' and arranged hollow substantially as
described and illustrated.
3. In wheels for railway and like vehicles the combination of two plates B
welded at their bosses 6º and periphery with an ordinary tyre substantially as
described.

cast together with a space between filled with wood or other light material.
