PROVISIONAL SPECIFICATION.
A Certain New or Improved Metal or Admixture of Metals.
We WILFRED VAN WART of 582, Moseley Road Birmingham Metal
Merchant, FRANZ WILLIAM POPP of 28, Ludgate Hill Birminghamı Merchant
and JOSEPH JOHN BRADLEY of 16 Buckingham Street Birmingham Metal
Caster, do hereby declare the nature of this invention to be as follows:-
This invention has reference to the manufacture of a new metal composed of an
admixture of metals and alloys and one method consists in a combination of aluminium,
tin and copper, and in certain cases a suitable proportion of nickel or any other
metal which may answer the same purpose as nickel may be added for the purpose
of hardening and whitening.
As an example of the formula, we employ the above named metals in or about
the following proportions.
We take of aluminium 100 parts more or less alloyed with from 1 to 25 parts
of copper and with from 1 to 25 parts of tin and as above stated when required
we may add to this mixture a proportion of nickel or other metal in from 1 to
25 parts.
Or we may find it desirable to omit from the above mixture of metals the copper
or the tin and substitute in the place thereof from 1 to 25 parts of the nickel or
other metal.
Or we may compound the mixture of say 100 parts more or less of aluminium
alloyed with from 1 to 50 parts of tin alone.
The object which we have in view is to produce an improved stronger and
lighter metal for spinning, casting, rolling, stamping and drawing, into tubes or wire
and for all cther purposes for which it may be used and also to produce a metal
which shall be non-corrosive.
We have set forth in the above description the component parts as also the
proportions in which we employ them but it may be found necessary or expedient
in some cases to add other metals or substances in order to improve the same in
whatever proportions we may think fit; but although we have mentioned that we
may add to or subtract from the said component parts as above described, those we
prefer to employ for general purposes of manufacture consist of the admixture of
the aluminium, copper and tin with sometimes the addition of nickel, or other metal.

page_text: Caster, 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 has reference to the manufacture of a new or improved metal
composed of an admixture of certain metals and alloys with aluminium and which
whilst we retain all the good qualities of aluminium such as extreme lightness non-
corrosiveness and effective appearance etc., we are enabled by our amalgamation of
metals and alloys to greatly improve these good qualities and add a very considerable
number of others which aluminium does not possess.
As is well known aluminium by itself though valuable for some purposes is
practically useless for the majority of industrial trades in which metals are used as
it is very unreliable when being worked up, and therefore will not produce
satisfactorily such articles as tubes, sheets wire, castings, and the like, in fact it
has been found almost impossible to produce a reliable weldless solid drawn tube
from aluminium alone. Then again, castings made of it cannot be successfully
used owing to their imperfect manufacture by reason of the "blow holes" which
present themselves during the working up of the aluminium.
In addition to the above illustration of defects that belong to the aluminium by
itself, the soft nature of the metal obviously affords comparatively little tensile
strength, but is weak under compression and bending tests. Now to overcome
these difficulties, the object which we have in view is to produce a new or
improved stronger metal which shall be as light as aluminium for spinning, casting,
rolling, stamping and drawing into tubes, and wire and producing sheets and for
all other purposes for which it may be applicable and our invention consists in
producing a metal composed of aluminium copper, tin, zinc, silver, and regulus of
antimony which we mix in any suitable proportions, we may find desirable
according to the purposes for which it may be required.
In the course of our experimental work we have found that the addition of zinc,
silver and regulus of antimony to the aluminium, copper, and tin, greatly increases
the utility and effectiveness of the metal we produce, and we also find that the
quantities of the component parts which we shall usually employ in carrying out
our invention will best meet our requirements as indicated in the formula which is
preferably as follows:-

page_text: without departing in any material degree from the essential elements of our said
invention.
In order that our new or improved metal according to the above formula of
component parts may at all times be made suitable for the various purposes for
which it is intended we do not desire to confine ourselves to the exact proportions
relatively as the same may be altered within the proportions named as by making
such alterations the metal can be made harder or softer and consequently of different
degrees of tensile strength.
By the admixture of the various metals with aluminium as specified, we produce
a metal principally of aluminium as will be seen, but which can with great
advantage be used in various manufactures which it would be impossible to inake
successfully of pure aluminium, we retain the extreme lightness and non-corrosive
properties of aluminium as stated, we also gain a much superior colour and con-
sequently finish. Amongst other advantages for some of the purposes for which
we shall use it, perfect castings free from blemish and blow holes can be turned
out, it can he readily rolled into very thin sheets, it can be drawn into wire and
into solid drawn seamless tubes, furthermore, the nature of the metal allows it to
take a very strong, clean and sharp screw thread which aluminium will not do,
being too soft.
We claim that our new metal is of much greater strength in all tensile bending
and compression tests which important points alone render it suitable for uses for
which aluminium could not be employed, and we are thus enabled by means of our
invention to adapt aluminium which is a comparatively little used metal into one of
universal importance.
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:
Firstly. The new or improved metal or admixture of metals in combination
consisting of an alloy or mixture, or alloys or mixtures of aluminium, copper, tin,
zinc, silver, and regulus of antimony, for the purposes of spinuing, casting, rolling
and drawing for producing shects, castings, tubes, wire and for other industrial
uses as set forth.
Secondly. The new or improved metal, or admixture of metals, forming one
combination consisting of aluminium, copper, tin, zinc, silver and regulus of antimony
in or about the proportions as set forth in the preceding formula and for the purposes
described.
Thirdly. We claim the herein described special amalgamation of the several
metals or alloys to produce our new or improved metal or the addition or sub-
stitution of any other metal or alloy or the omission of any one of the said alloys if
so required as set forth.
