PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Wheel Hubs for Cycles and
other Wheeled Vehicles.
We, HENRY JAMES BROOKES, of Cape Works, Cape Hill, near the City of
Birmingham, Cycle Manufacturer, and ALFRED BENJAMIN DAVIS, of No. 6, Bacchus
Road, Winson Green, Birmingham, aforesaid, Tool Maker, do hereby declare the
nature of this invention to be as follows:-
This invention relates to the manufacture of hubs, for the wheels of cycles and
other wheeled vehicles, from sheet metal or from lengths of solid-drawn tubing,
and has for its object, the simplification of means of forming the spoke flanges
and which consists in thinning or reducing the metal of the walls of the tubular
blank or length at the parts where the said flanges are to come.
The said thinning process is conducted either by a turning, spinning, rolling
or reeling process.
In carrying out one process according to my invention, I take a tubular blank
and annularly reduce the thickness of the parts of the same where the spoke
flanges are to come by a cutting or turning process or processes. Then by a rolling
process the annular bulging or swells are formed and as described in the Specifica-
tion of former Letters Patent granted to one of the present applicants, No. 17070
of 1896. The bulgings are then upset in the direction of the axis of the hub and
spoke flanges of a double thickness of metal are thereby produced.
According to another method the thinning of the metal at the desired parts
is effected by the application of pressure, as between rollers, which displaces the
same lengthwise and produces thin walls at the points operated.
This thinning process may be connected in any of the initial stages of producing
the hub, or the thinning may be done after the formation of the bulgings or swells,
and prior to the upsetting process.

page_text: Road, Winson Green, Birmingham, aforesaid, Tool Maker, 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 relates to the manufacture of hubs, for the wheels of cycles and
other wheeled vehicles, from sheet metal or from lengths of solid-drawn tubing,
and has for its object, the simplification of the process of forming the spoke flanges
thereof. The said invention consists in thinning or reducing the metal of the
walls of the tubular blanks or lengths at the parts where the said flanges are to
come.
ས་
The said thinning is conducted either by a turning, spinning, rolling or reeling
process.
In carrying out one process according to my invention, I take a tubular blank
and annularly reduce the thickness of the parts of the same where the spoke
flanges are to come by a cutting or turning process or processes. Then by a rolling
process the thinned parts are annularly bulged or swelled as described in the
Specification of former Letters Patent granted to one of the present applicants
No. 17070 of 1896. The bulgings are then end closed, collapsed or upset in the
direction of the axis of the hub and spoke or equivalent flanges of a double thick-
ness of metal are thereby produced.
By thus thinning the parts of the metal to be bulged and collapsed, the forma-
tion of the spoke flanges is greatly facilitated and a correspondingly lighter hub
is obtained without impairing the strength.
According to another method, the thinning of the metal at the desired parts
may be effected by the application of pressure, such as by spinning between rollers,
which displaces the metal lengthwise and produces thin walls at the points operated
upon.
This thinning process may be conducted in any of the initial stages of producing
the hub, or the thinning may be done after the formation of the bulgings or swells,
and prior to the upsetting process.
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:
In the manufacture of wheel hubs from tubular blanks in which spoke or like
flanges are formed integrally therewith by outward bulging and end closing or
upsetting processes;-thinning or reducing the metal of the walls of the tubular
blanks or lengths at the parts where the said flanges are to come, in the ways and
for the purpose herein set forth.
