Improvements in the Frames of Umbrellas and Parasols.
We, HENRY ELLIS, of 49 and 51 Ludgate Hill, in the City of London, and
BRIAN GEORGE COLEBY, of "Heathcot" Marlboro' Road, Putney, in the County
of Surrey, do hereby declare the nature of this invention to be as follows :-
In the ribs and stretchers of umbrellas and the like great elasticity is required;
at the present time they are usually made of sheet steel and of what is known as
the paragon or trough like form. We find however that these paragon ribs and
stretchers may more advantageously be made of alloys of aluminium specially
prepared with a view to hardness, stiffness and elasticity. Such an alloy consists
of eighty eight parts per cent. or thereabout aluminium, eight parts or thereabout
copper, and four parts or thereabout of nickel. Another suitable alloy consists of
eighty eight parts aluminium nine parts copper and three parts zinc. Amongst
the advantages of making paragon or trough like ribs and stretchers of these
aluminium alloys are the freedom from liability to rust or corrode and the
comparative lightness of the new metal.
The same alloys may be used in other parts of the frames of umbrellas and
parasols, the stick especially may consist of a tube of either of the new metals.

the same is to be performed to be particularly described and ascertained in and
by the following statement:-

formed of equal parts of the ingredients of the above mentioned alloys that is to
say consisting of 88 parts or thereabout of aluminium, 8 parts or thereabout of
copper, 2 parts or thereabout of nickel and 1½ parts or thereabout of zinc is in some
respects superior to either. Amongst the advantages of making paragon or trough
like ribs and stretchers of these aluminium alloys are the freedom from liability to
rust or corrode and the comparative lightness of the new metal.

page_text: The same alloys may be used in other parts of the frames of umbrellas and
parasols, the stick especially may consist of a tube of either of the new metals.
In making paragon ribs and stretchers these new metals are worked in the same
way as steel.
For making the various fittings appertaining to the frames of umbrellas and
parasols these new metals can be cast in moulds, rolled into sheets, drawn into tubes
and stamped in dies and generally they may be worked as brass is commonly used
in umbrella fittings.
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 :-
Umbrella and parasol frames composed wholly or in part of the new aluminium
alloys substantially as herein set forth.

A New Alloy, applicable for Umbrella Fittings, and for other
Uses where a Non-corrodible, Strong, and Light Metal is
required.
We, HENRY ELLIS, of 49. and 51 Ludgate Hill, in the City of London, and
BRIAN GEORGE COLEBY, of Heathcot, Marlboro' Road, Putney, in the County
of Surrey, do hereby declare the nature of this invention to be as follows:-
This invention has for its object a new alloy applicable for umbrella fittings,
and for other uses where a non-corrodible, strong and light metal is required.
This new alloy we term "Improved non-corrodible electric metal"; it is a triple
alloy of aluminium, copper and nickel. These metals are. combined in about the
following proportions:

many purposes suitable to replace for example the metallic parts of bicycles and
like vehicles and the spines and covers of fans inay with much advantage be made
of this alloy or combination of metals. Especially also it is suitable for use in the
manufacture of umbrellas; this forms the subject of another Patent granted to us
also numbered 16003 and dated the 22nd August 1894.
