PROVISIONAL SPECIFICATION.
Improvements in and in the Manufacture of Wheels.
We, WALTER HENRY CORKER, of The Hollins, Goldthorn Road, Wolverhampton,
in the County of Stafford, Manufacturor, and CHARLES HARRY PAGE, of The Eagle
House, Penn Fields, near Wolverhampton, aforesaid, Iron Master, do hereby
declare the nature of this invention to be as follows:-
This invention has for its object to construct wheels, more especially for cycles
and other light vehicles, in a manner which is very economical, and ensures great
strength combined with lightness of construction.
In constructing a wheel according to this invention, the usual spokes are dis-
pensed with and two circular dished plates of sheet metal are used to form the
sides of the wheel, and these plates are placed with their concave sides towards
one another and are fixed together at or near their outer edges where they meet or
are nearest to one another, and are joined together at their middles by the hub.
When a wheel constructed in the manner above described is required to be
formed to receive a pneumatic or other elastic tyre, the grooved or channelled
rim for such tyre may be formed by suitably shaping the edges of the side plates,
preferably before the plates are put together; and if no elastic tyre is required,
the desired form of rim for use without a tyre may be produced also by suitably
shaping the edges of the side plates. An elastic tyre, or a metal tyre, or, if
desired, a metal rim to receive an elastic tyre, may be formed with a flange or web
which passes between the edges of the plates and is securely held between the
plates.
The circular pieces of metal forming the side plates may be formed to the shape
desired, both in regard to the dishing and to the formation of the edges, by pressing,
stamping, or spinning, or partly by one process and partly by another or others.
The side plates may be formed, it desired, with openings therethrough to lighten
them and add to their appearance, and they may, if desired, be strengthened
by means of concentric or radiating corrugations.
The plates may be fixed to the hub, and also to one another, by brazing,
riveting, or in other convenient manner.

We, WALTER HENRY CORKER, of The Hollins, Goldthorn Road, Wolverhampton,
in the County of Stafford, Manufacturer, and CHARLES HARRY PAGE, of The Eagle
House, Penn Fields, near Wolverhampton, aforesaid, Iron Master, 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 to construct wheels, more especially for cyclos
and other light vehicles, in a manner which is very economical, and ensures great
strength combined with lightness of construction.
In constructing a wheel according to this invention, the usual spokes are dis-
pensed with and two circular dished plates of sheet metal are used to form the
sides of the wheel, and these plates are placed with their concave sides towards
one another and are fixed together at or near their outer edges where they meet or
are nearest to one another, and are joined together at their middles by the hub..
When a wheel constructed in the manner above described is required to be
formed to receive a pneumatic or other tyre, the grooved or channelled rim for such
tyre may be formed by suitably shaping the edges of the side plates, preferably
before the plates are put together; and if no elastic or other tyre is required,
the desired form of rim for use without a tyre may be produced also by suitably
shaping the edges of the side plates. An elastic tyre, or a metal tyre, or, if
desired, a metal rim to receive an elastic or other tyre, may be formed with a flauge
or web which passes between the edges of the plates and is securely held between
the plates.
The circular pieces of metal forming the side platos may be formed to the shape
desired, both in regard to the dishing and to the formation of the edges, by stamping,
pressing or spinning, or partly by one process and partly by another or others.
The side plates may be formed, if desired, with openings therethrough to lighten
them and add to their appearance, and they may, if desired, be strengthened
by means of concentric or radiating corrugations, or by means of both concentric
and radiating corrugations.
The plates may be fixed to the hub, and also to one another, by screws or rivets,
or in other convenient manner.
In order that the invention may be clearly understood, we will proceed to
describe, by way of example, practical applications of the same, which are illus-
trated in the accompanying drawings. Of these, Figure 1 is a side elevation of a
wheel, constructed according to this invention, having a rim adapted to receive
a pneumatic tyre; Figure 2 is a section taken on line of Figure 1; Figure 3
shews a modified section of rim adapted to receive a web of the tyre; and Figure 4
shews in sectional view a separately made rim fixed between the edges of the side
plates.
Referring first to Figures 1 and 2, A A are the dished plates forming the sides
of the wheel. The outer edges of these plates are shaped so that they logether
form a groove or channel for the reception of the tyre B. The two dished
plates AA are fixed to flanges a of the hub C by means of screws b, and are
fixed together near their outer edges, as shewn, by means of rivets or screws c.
The plates AA are shewn to be strengthened by means of radiating corrugations d,
which extend from the middle thereof to the rim into which they die out as
indicated at ee; and, in order to stiffen the portions of the rim which extend
between the corrugations d, short corrugations f are formed as gussets in the
angles which the dished portions of the plates make with the rim. The plates A
may be formed with concentric corrugations in lieu of, or in addition to, the
radiating corrugations d, as will be understood.

page_text: In the modification shewn by Figure 3, the rim, of which half is formed of the
metal at the edge of each plate A, is shaped with a deep groove g to receive a
corresponding web formed around the inner portion of the tyre B, and bolts or
rivets pass through both sides of this groove and through the web, thus securely
holding the tyre from becoming detached from the rim.
In the arrangement shewn by Figure 4 the rim D is formed separately from
the plates A A. The rim is formed with a web i which is placed in position
between the outer edges of the plates AA. The outer edges of the plates are
fixed to one another and to the web i of the rim by means of rivets or screws k
which pass through both the plates and through the web.
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: —
1. A wheel of which the two sides are formed of dished plates placed with their
concave surfaces towards one another, such plates being connected with one
another at the middle by means of the hub, and at or near their outer edges by
means of screws or rivets or in other convenient manner, substantially as described.
2. A wheel of which the two sides are formed of dished plates placed with
their concave surfaces towards one another, such plates being connected with
one another at the middle by means of the hub, and near their outer edges by
means of screws or rivets or in other convenient manner, such outer edges being
shaped to form a groove or channel to receive a pneumatic or other tyre, sub-
stantially as described.
3. The improvements in the manufacture of wheels which consist in forming
the sides and rims thereof, in sheet metal, by so shaping, by the process of
stamping pressing or spinning, or partly by one process and partly by another
or others, two separate pieces of such metal that when fixed together with their
concave surfaces facing one another they fulfil the intended purpose, substantially
as described.
