PROVISIONAL SPECIFICATION.
Improvements in and connected with the Construction of Cranks,
Back and Front Ends, Brake Levers, and other Parts of Cycles
and other Vehicles.
We, JAMES ARDLEY of 18, Inworth Street, Battersea, Engineer, and VINCENT
HUGHES of 38, Chancery Lane, London, Gentleman, do hereby declare the nature
of this invention to be as follows:-
Our invention relates to the construction of front and back ends, cranks and other
parts of cycles and other vehicles, when such parts are made of aluminium or an alloy
thereof, and the object is to render possible the employment of that metal in those
parts where it and its alloys would, owing to its brittleness, be at present inadmissible.
In carrying out our invention we proceed in or in about as follows:-We form the
parts to be constructed of metal (preferably steel) of T. H. oval, circular or other cross
section; to which are brazed or otherwise suitably attached steel rings or other
formations wherever openings are required in the said parts for the passage of spindles
or other parts of the machine or for other purposes. The steel parts above mentioned
are then placed in a suitable mould and molten aluminium or an alloy thereof poured
in, the result being that the steel parts (except the inner diameter of the rings or the
like) are surrounded by the aluminium. Provision may be made in forming the
mould for grooving out the aluminium in various parts to lighten the construction.
In cases where the cores are of T. H. or similar angular cross section-they will be
completely surrounded by the aluminium, but in cases where the cores are of circular,
oval, or other tubular, cross-section only the outer surfaces are covered with the
aluminium, the interior of the construction remaining hollow.

We, JAMES ARDLEY, of 18, Inworth Street, Battersea, Engineer, and VINCENT
HUGHES, of 38, Chancery Lane, London, Gentleman, 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 :-
Our invention relates to the construction of front and back fork ends, cranks, and
other parts of cycles and other vehicles, when such parts are made of aluminium, or
of an alloy containing that metal, and the object is to render possible the employment
of that metal in those parts where it and alloys containing it are, owing to brittleness,
at present inadmissable.

page_text: In carrying our invention into practice, we proceed in or in about the following
manner. We form the parts of the machine of metal (preferably steel) of T. H. oval,
circular, or other cross section, to which are brazed or otherwise suitably attached
steel rings or other formations wherever openings are required in the said parts, for
the passage of spindles or other parts of the machine, or for any other purposes. The
metal (preferably steel) parts above mentioned, are then placed in a suitable mould,
and molten aluminium or an alloy containing that metal poured in, whereupon the
steel or other parts (except the inner diameter of the rings or the like) are surrounded
by the aluminium. Provision may be made in forming the mould for grooving out
the aluminium in various parts to lighten the construction. In cases where the cores
are of T. H. or other angular cross section, they will be completely surrounded by the
aluminium, but in cases where the cores are of circular, oval, or other solid or tubular
cross section, only the outer surfaces are covered with the aluminium.
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 :-
Constructing cranks, back and front fork ends, and other parts of cycles and other
vehicles with a core or with cores of other metal than aluminium, preferably steel, the
said core or cores being of any cross section and tubular or solid, and surrounded or
covered by or embedded in aluminium by placing them, in suitable moulds and
pouring therein aluminium or an alloy containing that metal, the whole substantially
as described in the above specification.
