page_text: I, ROBERT COCKBURN, of Cumbrae House, Dumbreck, in the City of Glasgow,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention has for its object the production from wrought iron or steel of
light, strong and inexpensive wheels adapted mainly for use in wheel barrows but
also applicable to other vehicles.
Under one modification of the invention the wheel is made up of a thin web or
dise of sheet iron or steel which is strengthened to resist buckling or lateral flexure
by corrugations extending radially after the manner of spokes or in the form of
concentric annuli, the web being by preference creased or stamped from the sheet.
A central orifice is left for the passage of the shaft, or axle, and on each side is
attached by riveting or otherwise a washer creased or formed to provide an
extended bearing on the shaft on each side of the web, or the web may be creased
to form the bearing on one side whilst a washer is attached to it to form the bearing
on the other side. In either case the wheel nave thus formed may be shrunk on
to the shaft or axle. The rim or tyre of the wheel which may be of tee, angle or
plain hoop section is attached by riveting or like means to the web, the outer rim
of the web being flanged or bent over for convenience of attachment when a plain
hoop ring is used.
Under another modification the web instead of being in the form of a disc is
composed of two bars each split at its ends and spread to approximately X shape
to form radial arms or spokes extending from the nave to the rim. The two bars
are laid cross-wise one over the other so that the arms or spokes divide the wheel
into equal segments. A creased up eye is formed on each bar at the centre and
when the bars are fitted together the creased parts form a nave having a suitable
bearing on the shaft or axle on which the nave so formed is shrunk.
The outer ends of the radial arms or spokes may be bent or flanged for attach-
ment to a hoop like rim or tyre or they may be flat and attached to the web.of
a T or angle iron rim, or again they may be carried through orifices in the rim
and the ends riveted therein.

COMPLETE SPECIFICATION.
Improvements in Wheels for Vehicles.
I, ROBERT COCKBURN, of Cumbrae House, Dumbreck, in the City of Glasgow,
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 has for its object the production from wrought iron or steel of

Improvements in Wheels for Vehicles.
I, ROBERT COCKBURN, of Cumbrae House, Dumbreck, in the City of Glasgow,
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 has for its object the production from wrought iron or steel of
light, strong and inexpensive wheels adapted mainly for use in wheel barrows but
also applicable to other vehicles.

page_text: The invention is illustrated under several modifications by the accompanying
drawings in which Figures 1 and 2, 3 and 4, 5 and 6 are respectively front elevation
and vertical sections of the improved wheel.
Under one modification of the invention and as illustrated by Figures 1 and 2
the wheel A is made up of a thin web or disc B of sheet iron or steel which is
strengthened to resist buckling or lateral flexure by corrugations extending radially
after the manner of spokes or in the form of concentric annuli, the web B being
by preference creased or stamped from the sheet. A central orifice C is left for
the passage of the shaft or axle D, and on each side is attached, by riveting or
otherwise, a washer E creased or formed to provide an extended bearing on the
shaft D ou each side of the web B; or the web B may be creased to form the
bearing on one side whilst a washer is attached to it to form the bearing on
the other side. In either case the wheel nave E thus formed may be shrunk on
to the shaft or axle D. The rim or tyre F of the wheel which may be of tee,
angle or plain hoop section is attached by riveting or like means to the web B,
the outer rim of the web B being flanged or bent over for couvenience of attachment
when a plain hoop ring F is used.
Under another modification illustrated by Figures 3 and 4 the web instead of
being in the form of a disc is composed of two bars B each split at its ends and
spread to approximately X-shape to form radial arms or spokes extending from the
nave E to the rim F. The two bars B are laid cross-wise one over the other so
that the arms or spokes divide the wheel A into equal segments. A creased up
eye is formed on each bar at the centre and when the bars B are fitted together
the creased parts form a nave E having a suitable bearing on the shaft or axle D
on which the nave so formed is shrunk.
The outer ends of the radial arms or spokes may be bent or flanged as at f for
attachment to a hoop-like rim or tyre F or they may be flat and attached to the
web of a T or angle iron rim as at f¹ or again they may be carried through
orifices in the rim and the ends riveted therein.
Under the modification represented by Figures 5 and 6 the wheel A has three or
more spokes B on either side of the rim F welded together at their inner ends to
form the axle D as shewn, the outer ends being welded to the rim in which recesses
are cut for the reception of the spokes, shoulders being formed thereon in the
welding operation to bear against the inner periphery of the rim.
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 I
claim is :-
A wheel for use in wheel-barrows and other vehicles constructed substantially
as described under several modifications with reference to the annexed drawings.
