PROVISIONAL SPECIFICATION.
An Improved Metallic Alloy, more especially intended for use for
Gas or Petroleum Engine Igniters or like articles subjected to
Great Heat.
I CHARLES WILLIAM PINKNEY of Raglan Road, Smethwick in the County
of Stafford Engineer do hereby declare the nature of my invention. to be as
follows:-
:-
My invention is intended more especially to provide a gas engine or petroleum
engine igniter tube or thimble which will be more durable and efficient than such
tubes or thimbles as hitherto made but my invention may also be used for other
articles which are subjected to great heat. According to my invention I make the
tubes or thimbles of cast iron or like metal of close texture such as that usually
known as hydraulic iron with which is combined nickel to form a considerable
proportion of the alloy usually I prefer to employ about equal proportions of the
said iron or like metal and the nickel.
The alloy may be formed most conveniently by first melting the nickel and then
introducing the iron in a divided state such as in the form of borings for
example.
The articles may be cast or otherwise formed from the alloy in any usual or
suitable way.
Dated this 20th day of October 1891.

COMPLETE SPECIFICATION.
An Improved Metallic Alloy, more especially intended for use for
Gas or Petroleum Engine Igniters or like articles subjected to
Great Heat.
I CHARLES WILLIAM PINKNEY of Raglan Road Smethwick in the County
of Stafford Engineer 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 :-
My invention is intended more especially to provide a gas engine or petroleum
engine igniter tube or thimble which will be more durable and efficient than such
tubes or thimbles as hitherto made, but my invention may also be used for other
articles which are subjected to great heat such as vapourisers, lamps and burners.
According to my invention I make the tubes or thimbles (or other article to be
subjected to high heat) of cast iron or like metal of close texture such as mild steel,
Bessemer steel, or charcoal iron or what is usually known as hydraulic cast iron
(preferably the latter) with which I combine or alloy nickel in such quantity as to
form a considerable proportion of the alloy. Usually I prefer to employ about
equal proportions of the said iron or like metal and the nickel. The alloy may be
formed most conveniently by first melting the nickel and then introducing the iron
in a divided state such as in the form of borings for example.
The articles may be cast or otherwise formed from the alloy in any usual or
suitable way.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
A metallic alloy of nickel and cast iron or like metal as-hereinbefore defined for
the purposes described.
