IMPROVEMENT IN THE CONSTRUCTING WHEELS FOR BICYCLES, TRICYCLES OR ANY OTHER VEHICLES OR PURPOSES
Year: 1884

page_text: COMPLETE SPECIFICATION.
I SIDNEY BOLTON KINCAID, Master of The Grammar School of Guildford in
the county of Surrey do hereby declare the nature of my invention for AN
IMPROVEMENT IN THE CONSTRUCTING WHEELS FOR BICYCLES, TRICYCLES OR ANY
OTHER VEHICLES OR PURPOSES and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:-
The wheels are constructed by using in place of spokes two thin plates whose
surfaces are either frustra of a right circular cone or portions of a spheroidal or any
other surface of rotation, these plates being set at a greater distance apart at the
axle than at the tire.
These plates may be of any suitable material and may be coated or plated with
any material.
Also the plates may be corrugated or embossed or perforated in any way.
Also any convenient method of securing them to the axle or hub and to the tire
or circumference may be used.
I prefer, but, as aforesaid, this is not material to the invention, that the plates
should be of thin steel, either painted, or plated with nickel, or bare, and that they
should be of the form of frustra of a right cone and without perforations or
corrugations or embossment. A section of such a wheel is shown in fig. 1, where
the plates P are secured to a V shaped tire or circumference Tadapted to receive an
indiarubber tire by being bent out to the same angle as the V and attached to it
by a number of small rivets R. The plates are attached to the axle A by being
placed between the hubs or cheeks H and secured by screws S passing through the
outside cheeks and through the plates and screwing into the inside cheek as a nut,
these cheeks being keyed, or otherwise secured, to the axle; but as aforesaid they
may be fastened to the axle or to the tire in any other way.
Fig. 2 shows, in section, a wheel with perforations at p and baving a circum-
ference to receive an indiarubber tire formed of the plates themselves which are
bent so as when rivetted together to form a V shaped groove. K is the key which
secures to the axle.
Fig. 4 shows a wheel in which the plates form portions of a spheroidal
surface, with the concave sides inward, and are secured to a solid tire by rivets
passing through the tire and plates. A conical plate can be formed by cutting out
of sheet metal a figure like fig. 3 (i.e. a circle with a hole in the centre and a sector

page_text: removed) and bringing the edges of the removed sector together and securing them
by rivetting or otherwise; but I prefer to form the plates by pressing them
between dies of sufficient size or by hammering or in any other way that avoids
the necessity of joining.
Fig. 5 shows a perspective view of a spoked wheel A and of an improved plate
wheel K.
Such a wheel as herein described is stronger, especially as regards liability to
injury by blows or strains out of the plane of the circumference, and also is easier
to run than one made in the usual way. It can also be made more cheaply and is
less trouble to clean.
The drawings are not made to scale, and for the sake of clearness some parts are
purposely much exaggerated.
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
1° The construction of wheels by the substitution of two thin plates of metal,
set farther apart at the axle than at the circumference, in place of spokes.
2° The adaptation of such wheels to bicycles, tricycles, and other vehicles.
Dated this thirteenth day of November 1884.
