page_text: and such like Purposes.
We, GEORGE ALLAN of Corngreaves Iron Works near Birmingham, Engineer,
and THO TURNER of Corngreaves Iron Works near Birmingham, Engineer do
hereby declare the nature of this invention to be as follows:-
Our invention relates to a process whereby we produce bars of metal presenting
a surface so variegated that when they are coiled and welded as in forming a twist
barrel, the surface of the barrel when it is polished and coloured in the usual way,
presents a pattern of helical streaks of light and dark colour alternating with
each other.
For this purpose, we first arrange in an ingot mould, a number of bars of iron
lengthwise of the mould with intervals between them and we pour into the mould
melted steel which surrounds and encloses these bars and becomes in a manuer
welded to them. We then by rolling lengthwise draw down this compound ingot
in breadth or thickness or in both these dimensions but chiefly in thickness
proportionately elongating it. So far the process corresponds with that which is
described in the Specification of Rose's Patent N° 16,147 of 1884. Having
sufficiently elongated the compound bar and reduced its transverse section to the
form of a long rectangle, we now cut it transversely into a number of slabs each
of which presents on its cut surfaces sections of the iron and of the steel
interspersed therewith, the iron sections shewing themselves more or less elongated.
We then roll each of these slabs in the direction of its length tous greatly
elongating the iron portions, so that they present themselves as thin streaks
alternating with streaks of steel and we thus produce a variegated bar suitable
for such purposes as forming twist barrels. The iron bars originally placed in the
mould may be of square, rectangular, polygonal, round or other section and they
may be disposed in the mould in various arrangements and attitudes so that, when
their sections come to be elongated as described, they may present various patterns
determined by the original forms and arrangements of the bars and the extent of
the successive drawings to which they are subjected.

and such like Purposes.
We, GEORGE ALLAN of Corngreaves Iron Works near Birmingham, Engineer
and THO TURNER of Corngreaves Iron Works near Birmingham Engineer do
hereby declare the nature of our 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 a process whereby we produce bars of metal presenting
a surface so variegated that when they are coiled and welded as in forming a twist
barrel, the surface of the barrel when it is polished and coloured in the usual way,
presents a pattern of helical streaks of light and dark colour alternating with
each other.
For this purpose, we first arrange in an ingot mould, a number of bars of iron
or steel with intervals between them and we pour into the mould melted steel
which surrounds and encloses these bars and becomes in a manner welded to them.
We then by rolling lengthwise draw down this compound ingot in breadth or
thickness or in both these dimensions but chiefly in thickness proportionately
elongating it. So far the process corresponds with that which is described in the
Specification of Rose's Patent No 16,147 of 1884. Having sufficiently elongated
the compound bar and reduced its transverse section to the form of a long
rectangle, we now cut it tranversely into a number of slabs each of which presents
on its cut surfaces sections of the bars and of the steel interspersed therewith, the
bar sections shewing themselves more or less elongated. We then roll each of
these slabs in the direction of its length, thus greatly elongating the bar portions, so
that they present themselves as thin streaks, and we thus produce a variegated bar
suitable for such purposes as forming twist barrels. The bars originally placed in
the mould may be of square, rectangular, polygonal, round or other section and
they may be disposed in the mould in various arrangements and attitudes so that,
when their sections come to be elongated as described, they may present various
patterns determined by the original forms and arrangements of the bars and the
extent of the successive drawings to which they are subjected.
Fig. 1 of the accompanying drawings represents an ingot of steel in which are
included in the manner described a number of bars of rectangular section. This,
when rolled, is elongated and thinned as shewn by Fig. 2, the internal bars being
proportionately thinned and widened. This rolled ingot being cut into lengths as
indicated by the dotted lines in Fig. 2 produces a number of slabs each such as is
shewn by Fig. 3. Each of these slabs being now rolled, a bar is produced such as
is shewn by Fig. 4, presenting a variegated surface. In & similar way the ingot
partly shewn by Fig. 5 may be rolled and cut to lengths each a slab like Fig. 6,
and these may again be rolled producing variegated bars such as are shewu by
Fig. 7. There may be many different arrangements of the bars in the primary
ingot; and these bars may themselves be of compound metal; Figs. 8 and 9 are
examples shewing compound bars included in a compound ingot.

page_text: 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
The process for manufacturing variegated metal by casting a steel ingot
including bars arranged in the mould, rolling the ingot to increased length and
width, cutting it into slabs and then rolling the slabs into bars, substantially as
herein described.
