PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Metallic Hubs for the Wheels
of Bicycles and other Velocipedes, Motor Carriages, and Road
Vehicles.
We, GEORGE HENRY MIDDLETON and GEORGE MACBETH, trading together as
Middleton and Macbeth, of 53, Oliver Street, in the City of Birmingham, Metal
Spinners, do hereby declare the nature of this invention to be as follows:-
This invention consists of the hereindescribed improvements in the manufacture
of metallic hubs for the wheels of bicycles and other velocipedes motor carriages
and road vehicles generally.
;
In carrying out this invention we take a thin steel or other ductile metal tube
of somewhere about the same length as is the required wheel hub and by tools in a
press or by rolling in a lathe or by other means we reduce the diameter of the
end portions of the tube and form shoulders or rebates thereon at a short distance
from each end corresponding with where the flanges for the spokes are to be.
Each of these flanges is formed of an annular sheet metal blank with a central
raised boss adapted to fit on to the shouldered down part of the tube which forms
the body of the hub. The shoulders keep the flanges true and at the proper
distance apart. The said flanges are secured in place by any convenient
means as by each of the boss parts of the flanges having one two three or more
inwardly projecting tongues formed with it which are bent back and take through
holes formed in the tubular body of the hub and are then bent up inside the hub
thus effectually securing the hub and flanges together. Both of the said flanges
are formed and fixed to the tubular part of the hub in the manner above described.
The central portion of the tubular hub, that is the part between the shoulders
where the flanges fit on, may if desired be swaged or otherwise reduced in diameter
so as to give a better appearance to the hub. The end portions of the tubular
part of the hub are made of the proper size to receive the cups for the ball bearings
and when the hub is required for a back wheel of a bicycle or other wheel which
has a sprocket wheel fixed on it, the said tubular part is screw threaded as usual
to receive the sprocket wheel.

We, GEORGE HENRY MIDDLETON and GEORGE MACBETH, trading together as
Middleton & Macbeth, of 53, Oliver Street, in the City of Birmingham, Metal
Spinners, 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 consists of the herein described improvements in the manufacture
of metallic hubs for the wheels of bicycles and other velocipedes motor carriages.
and road vehicles generally.
We will describe this invention by referring to the accompanying drawings on
which Fig. 1 is a longitudinal sectional elevation of a wheel hub constructed in
accordance with this invention; Fig. shews a piece of the tubular, body of the
hub separate from the flanges; Figs. 3 and 4 shew the two parts of one of the
flanges of the said hub and Figs. 5 and 6 are longitudinal sectional elevations of
slightly modified forms of the flange and portion of the hub and Fig. 7 shews a
further modified form of the said wheel hub.
The same letters of reference indicate the same or corresponding parts in all
the figures of the drawings.
In carrying out this invention we take a thin steel or other ductile metal tube A
of somewhere about the same length as is the required wheel hub and by tools in a
press or by rolling in a lathe or by other means we reduce the diameter of the
end portions a¹a of the tube and form shoulders or rebates a³ a thereon at a
short distance from each end corresponding with where the flanges for the
spokes are to be. Each of these flanges, which are marked respectively B¹ B³,
is formed of an annular sheet metal blank shewn separately by Fig. 4
made with a central hole 61 adapted to fit on to the shouldered down part a¹
or a of the tube A which forms the body of the hub. The shoulders a³a of the
tube A keep the flanges B₁ B true and at the proper distance apart. The said
flanges B1 B2 are secured in place by any convenient means as by each of the
flanges having one, two, three or say four inwardly projecting tongues marked b³
formed with it which are bent back as shewn in Fig. 4 and take through corre-
sponding holes c formed in the shoulders a³ a³ of the tubular body A of the hub
and are or may be then bent up inside the hub as shewn in Fig. 5 or these tongues be
may be left straight as shewn in Figs. 1, 4, 6 and 7 in this case for furtner security
we provide for each flange a screw threaded ring (which rings are marked
respectively D¹ D²) screwed on to the parts a¹ a² of the hub tight up against the
flanges BB and the rings D1 D2 are pierced with spoke holes a corresponding
with the spoke holes 63 of the flanges B B2 so that the spokes can pass both
through the flange and through the ring and thus prevent the rings D¹ D³ from
coming unscrewed and the flanges getting loose. The central portion A of the
tubular hub that is the part between the shoulders a³ a where the flanges B¹ B
fit on may if desired be swaged or otherwise reduced in diameter smaller than the
shoulders a³ a as shewn in Figs. 6 and 7 so as to give a better appearance to the
hub. The end portions a5 a6 of the tubular part of the hub are made of the proper
size to receive the cups E1 E2 for the ball bearings and when the hub is required
for the back wheel of a bicycle or other wheel which has a sprocket wheel fixed
on it, the tubular part is at a screw threaded to receive the sprocket wheel.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:-
1. In a metallic hub for the wheels of bicycles and other velocipedes motor cars
and road vehicles, making the central tubular part A of the hub with shoulders a³ a*
to bear against the flanges for the spokes in combination with a projecting tongue
or tongues formed on said flanges which engage in corresponding holes in the
said shoulders for the purpose and substantially as set forth.
2. In a metallic hub for the wheels of bicycles and other velocipedes motor cars
and road vehicles, the combination of the central tubular part A made with
shoulders a3 at, the two flanges 131 132 cach made with a projecting tongue or
tongues b which engage in holes c in the said shoulders, and the rings D1 D2 which
are screwed
or otherwise fixed on to the end portions of the hub against the
flanges B1 B2 the said rings and flanges having holes through which the spokes pass
all substantially as hereinbefore described and illustrated by the accompanying
drawings.
