PROVISIONAL SPECIFICATION.
Improvements in the Construction of Wheels and Pulleys.
I, ROBERT HUDSON, of Gildersome Foundry, near Leeds, in the County of
York, Engineer and Iron Founder, do hereby declare the nature of this invention
to be as follows :-
This invention has reference to an improved construction of metallic wheels and
pulleys suitable for various purposes, whereby I am enabled to considerably
simplify, cheapen and facilitate their manufacture and greatly add to their
durability whilst at the same time obviating the necessity of shrinking on their
tyres.
To this end the spokes of a wheel or pulley according to my invention, instead
of each terminating at the hub or centre of the wheel or pulley as usual, are made
to terminate at the periphery only for which purpose they are composed of bars of
angular or other convenient section adapted to be secured at their central portions
to a hub or centre and at their ends to the rim of the wheel or pulley so that each
bar will form two spokes continuous with each other, thereby avoiding the formation
of joints in the spokes at the hub.
In one construction of wheel or pulley according to my invention there are eight
spokes formed by four bars of L or other convenient shape in cross section the
central portions of these bars being rivetted or otherwise secured to an annular
extension or flange on a metal hub or centre, and their outer ends, which are
suitably formed, being secured to rings that may be also of L or other convenient
shape in cross section and form the wheel rim to the outer side of which is, or may
be, secured an outer rim or tyre, which in the case of wheels for rolling stock,
would be flanged in the ordinary way.
In a modified construction the rings of or other cross section are replaced by a
single ring of L or T shape in cross section to the internal annular flange of which
the outer ends of the bars forming the spokes are suitably secured, as for example
by rivetting.
Improvements in the Construction of Wheels and Pulleys.
I, ROBERT HUDSON, of Gildersome Foundry, near Leeds, in the County of
York, Engineer and Iron Founder, 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 has reference to an improved construction of metallic wheels and
pulleys suitable for various purposes, whereby I am enabled to considerably

terminate at the periphery only for which purpose they are composed of bars of
angular or other convenient section adapted to be secured at their central portions
to a hub or centre and at their ends to the rim of the wheel or pulley so that

central portions of these bars being rivetted or otherwise secured to an annular

or may be, secured an outer rim or tyre, which in the case of wheels for rolling
stock, would be flanged in the ordinary way."
In the accompanying drawings,
Fig. 1 is a side elevation, and Fig. 2 a central vertical cross section, illustrating:
a wheel of the kind just referred to suitable for a vehicle.
It comprises four metal bars 1 of 1 shape in cross section, curved in the direction
of their length, and arranged to cross each other so as to form eight spokes. The
four bars are arranged in two pairs bent laterally at their central portions so as to
cross each other at opposite sides of an annular extension or flange 28 of a metal
hub or centre 2 to which they are connected it may be by bolts and nuts 3 as
shown, or by rivets, which serve also to secure in position curved metal bars 4
which act to stiffen or strengthen the said bars 1 at their central portions. At
their outer ends one of the sides or flanges of each bar is bent down upon the other
as shown at 5, and riveted between two metal rings 6 that are also of shape in
cross section and form the wheel rim. 7 is an outer rim or tyre secured upon the
said wheel rim, it may be by shrinking in the ordinary way.
Fig. 3 is a part cross section illustrating a modified construction in which the
angle iron rings 6 shown in Figs. 1 and 2, are replaced by a single ring 6* of
tee shape in cross section to the internal annular flange 65 of which the outer
flattened ends of the bars 1 forming the spokes are suitably secured, as for example
by riveting as shown.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A wheel or pulley in which the spokes are composed of bars of angular or
other suitable section secured at their central portions to a hub or centre and at
their ends to the rim of the wheel or pulley so that each bar will form two spokes
continuous with each other thereby avoiding the formation of joints in the spokes
at the hub substantially as herein described.
2. A wheel or pulley constructed substantially as described and shown or modified
as set forth.
