COMPLETE SPECIFICATION.
Improvements in Wheels.
ROBERT LESLIE, Cycle Manufacturer Post Office Buildings, Elgin in the
County of Elgin, Scotland, 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 making of wire spoked wheels so that they
cannot "buckle," double or collapse in any way and the making of a rim and tyre
for said wheel so that the rim shall be protected from the road while the peculiar
construction of the tyre renders riding easy and the replacement of broken spokes
simple and inexpensive.
The invention is applicable to wheels for cycles, perambulators, carriages, pulleys
and to wheels for all purposes that are built with wire spokes.
Hitherto it has been the practice to secure the spokes to the centre of the rim
but this invention consists in attaching the spokes to the rim at any point beyond
the centre of the rim, preferably-as shown by the drawings-to the sides of the
rim opposite to the flanges of the hub to which they are fixed-the spokes thus
cross each other and the further beyond the centre of the rim they are carried the
greater the stability of the wheel and by placing the spokes close to the edges of
the rim only a small part of the tyre requires to be raised when a broken spoke is
being replaced.
On pressure being applied to one side of the rim of a wheel constructed according
to this invention the spokes at opposite side pull directly against the depressed ones
and thus prevent the rim from turning aside as in "buckling."
By use of crossed spokes as hercin described it is practicable to employ hubs
having flanges in a direct line with the rim (Fig. 1) and this brings the chain
wheel near to the centre so that the cranks of a cycle may be brought within four
and a half inches of each other.
The rim is made hollow or solid as required, in either case the part which
receives the rubber-the inside of the rim is formed with flat flanges at the edges
to which the rubber tyre is cemented as well as to the bottom and the bottom is
made with a slightly raised and flat centre and with gutters on either side between
the flat raised centre and the aforesaid flanges.
The rubber tyre is constructed to fit into the gutters before mentioned and to
cement to the flanges of the rim.
Drawings accompany this Specification and fully explain the invention.

The usual arrangement of spokes is shown at Fig. IV by dotted lines-13 and
15 show the spokes at hub and 16 shows where they enter the rim. 17 shows the
chain wheel. 18 and 19 show spokes entering the rim exactly opposite each other.

page_text: Having described the invention and the manner in which it is to be carried out I
declare that what I claim is :-
1. The fixing of spokes to a wheel so that those from either flange of the hub
cross each other and are attached to the rim at any point beyond the centre of the
rim substantially as herein described.
2. The making of a rim with flanges at the sides on which the tyre rests
substantially as herein described.
3. The making of a cushioned or solid tyre in such a manner that it covers the
edges of the rim completely and protects it from wear substantially as described
herein.
