Complete Accepted, 27th May, 1887.
We, WILLIAM NEWZAM NICHOLSON and WILLIAM MATHER, both of Newark upon
Trent in the County of Nottingham, Agricultural Engineers do hereby declare the
nature of our said invention to be as follows :—
Our invention for improvements in Travelling wheels consists in making the spokes
of such wheels of a T section of Wrought Iron or Steel, the table of the T being
placed parallel with the tyer of the wheels. The inner ends of the spokes are cast
into the naves of the wheels and the outer ends butt against the inner sides of the
Tyers. The tyers of the wheels consist of either a single section of T Iron or Steel
bent with the web inwards, the table of the T forming the tread or they may be
formed of one or more rings of T or L Iron or Steel, surrounded by hoops of a flat
or convex section. The outer end of the spokes where they butt against the tyers are
formed with enlargements or other arrangements to receive the rivets that fasten them
to the tyers.
We prefer to make the spokes of T Iron as described, but we do not confine
ourselves to this particular section, as Iron or Steel of L U or H section may be used
without departing from the main principle and intention of our invention which is to
produce by the methods described, wheels of remarkable lightness and rigidity.

page_text: WILLIAM NEWZAM NICHOLSON and WILLIAM MATHER, both of Newark upon
Trent, in the County of Nottingham, Agricultural Engineers, do hereby declare the
nature of our said 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 consists in making the spokes of travelling wheels of a T section of
wrought iron or steel and is illustrated by Figures 1 and 2 of the accompanying sheet
of drawings, which show a wheel made on our improved plan in elevation and section
respectively.
The spokes A are placed with the table of the T parallel with the tyer of the wheel,
their inner ends are cast into the nave B of the wheel, whilst their outer ends butt
against the inner side of the tyer C and are provided with bosses or enlargements a
through which rivets pass to secure them to the tyer C.
Figure 4 shows these bosses on an enlarged scale. The tyers C consist of either a
single section of T iron or steel, as shown in Figures 1 and 2, bent with the web
inwards, the table of the T forming the tread of the wheel or they may be formed of
one or more rings of Lor T iron or steel C surrounded by hoops C of flat or convex
section as shown in section by Figure 3.
We prefer to make the spokes A of T iron or steel as described and shown in
Figures 1. 2. 3 and 4 but we do not confine ourselves to this particular section as iron
or steel of L, U, or H section, as shown in Figures 5. 6 and 7 respectively, may be
used, either with or without the bosses or enlargements a shown on the drawings,
without departing from the main principle and intention of our invention; which is
to produce by the methods above described wheels of remarkable lightness and
rigidity.
Having now particularly described and ascertained the nature of our said Invention
and in what manner the same is to be performed we declare that what we claim is :-
The formation of Travelling wheels having spokes of T, L, U, or H section of iron
or steel, the inner ends of such spokes being cast into the nave, and the outer ends
rivetted to a tyer consisting of one or more hoops of T or L section of iron or steel;
substantially as described and shown in the drawings.
