do hereby declare the nature of my said Invention for "IMPROVEMENTS IN SPRING
WHEELS FOR TRACTION ENGINES OR FOR OTHER PURPOSES" to be as follows:-
My Invention has for its object to provide simple efficient and durable spring
wheels for traction Engines or other purposes-According to my Invention I secure
to the rim lugs or plates having square or equivalently shaped holes therethrough
transversely affording a housing and bearing for similarly formed bars or rods. The
boss is provided with flanges or plates in which similar and corresponding holes are
made for carrying similar bars or rods. The connection between the rim and the boss
is made by curved spring "spokes" of steel having each end squared or bent over
into loops or formed with eyes to correspond with the section of the bars or rods
and the spokes are secured by passing the bars or rods through these loops or eyes
the curves of the spokes being arranged alternately in reverse directions-The
bars or rods are secured in position by split pins and washers so that the spokes
can be secured firmly in position without bolts and nuts which are objectionable in
practice Any of the spokes can be readily taken out and replaced by withdrawing
the split pins and washers from the bars or rods and then the bars or rods form the
holes in the lugs or plates and the eyes or loops in the ends of the spokes The
spokes are merely intended to carry the Engine the rim being driven by an arın on
the boss connected by a link with the rim. There may be any suitable number
of spring spokes employed in connection with each pair of square or equivalently
shaped bars or rods.

page_text: I, JAMES HUTCHINSON MANN, of 123 Roundhay Road, Leeds, Mechanical 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:―
My Invention has for its object to provide simple efficient and durable spring
wheels for traction engines or other purposes.
I will describe my Invention with reference to the accompanying Drawings,
Figure 1 of which is a side view and Figure 2 a transverse section of a spring
wheel constructed according to my Invention. I secure to the rim A lugs or
plates B having square or equivalently shaped holes transversely therethrough
affording a housing and bearing for similarly formed bars or rods C. The boss D
is provided with flanges or plates d in which similar and corresponding holes are
made for carrying similar bars or rods (2. The connection between the rim and
the boss is made by curved spring spokes E of steel having each end squared or
bent over into loops e or formed with eyes to correspond with the section of the
bars or rods C C² and the spokes are secured by passing the said bars or rods
through these loops or eyes the curves of the spokes being arranged alternately in
reverse directions. The bars or rods are secured in position by split pins and
washers so that the spokes can be secured firmly in position without bolts and nuts
which are objectionable in practice. Any of the spokes can be readily taken out
and replaced by withdrawing the split pins and washers from the bars or rods and
then the bars or rods from the holes in the lugs or plates and the eyes or loops in
the ends of the spokes. The spokes are merely intended to carry the engine the
rim being driven by arms G on the boss D connected by a link H with the rim A.
There may be any suitable number of spring spokes employed in connection with
each pair of square or equivalently shaped bars or rods. In the drawing the holes
in the plates and B on one side of the wheel only is shewn squared those on the
other side of the wheel being shewn round and the bolts C being correspondingly
formed at the parts which pass through these holes respectively, but the holes in all
the plates may be squared or equivalently shaped, the bolts C in that case being
squared to correspond. Or the holes in the plates on both sides of the wheel may
be round in which case the part of the bolts over which the eyes or loops of the
springs pass only would be squared or equivalently shaped to fit the said eyes or
loops. It will be understood that although I have shewn my mode of securing the
springs as applied to both the rim aud the boss yet that it may be used at either
the rim or boss in combination with other mode of fastening at the parts where
my Invention is not applied,

page_text: 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
First. In spring wheels for traction engines or for other uses springs having
eyes or loops of a squared or equivalent form at either or at each end through
which pass correspondingly formed bolts or bars securing the springs to the rim or
the boss or both substantially as hereinbefore described and illustrated by the
accompanying Drawings.
Second. A spring wheel constructed and arranged as hereinbefore described and
illustrated by the accompanying Drawings.
