Complete Specification Accepted, 14th Sept., 1888
I HOWARD LANE, of 115 Palmerston Buildings, in the City of London, Engineer,
do hereby declare the nature of my said invention to be as follows:-
My invention relates to the process known as the "spinning of metals," which, as
hitherto practised, consists in the application of pressure to a metal body, when fixed
to a revolving spindle, thus causing variations of form in such metal body, as
required.
My invention consists in applying heat to the metal, while being operated upon, as
above mentioned, such heat being derived from a furnace, in combination, or close
contiguity with, the mandrel, lathe, spindle, or shaft, which carries the revolving
metal under operation. The metal is thereby maintained in a ductile and malleable
condition.
I build my furnace either under the lathe or in any other suitable position, or I
apply a portable gas or other furnace thereto, for the purpose of rendering any
portion or portions of the metal soft and pliable, when acted upon by pressure.

I, HOWARD LANE of 115 Palmerston Buildings, in the City of London Engineer,
do hereby declare the nature of my said 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 relates to the process known as the "spinning of metals," which, as
hitherto practised, consists in the application of pressure to a metal body, when fixed
to a revolving spindle, thus causing variations of form in such metal body as
required.
My invention consists in applying heat to the-metal, while being operated upon, as
above mentioned, such heat being derived from a furnace, in combination, or close
contiguity with, the mandrel, lathe, spindle, or shaft, which carries the revolving
metal under operation. The metal is thereby maintained in a ductile and malleable
condition.
I build my furnace either under the lathe, or in any other suitable condition or 1
apply a portable gas or other furnace thereto for the purpose of rendering any portion
or portions of the metal soft and pliable, when acted upon by pressure.
And in order that my said invention may be particularly described and ascer-
tained, reference is hereby made to the accompanying drawings, in which similar
letters of reference indicate corresponding parts.
Fig. 1 illustrates one of the applications of my invention, in which a steel cartridge
case a is shown mounted in an ordinary lathe, the peculiar taper required being
produced under the action of the gas flame. a is the cartridge case under operation.
bis a pipe through which gas and air pass to a circular Bunsen burner c, surrounding
the cartridge case, whereby a number of jets of flame are directed towards the
metal.
Pressure is applied to the metal by means of a lever, or a tool held in a slide rest,
and pressed forward in the usual manner.
Fig. 2 is a transverse section, showing the application of my invention to the
manufacture of a torpedo case. f is the furnace. g is the spindle upon which the
mould is mounted.
kis the metal under operation, and 7 is a lever which is used to press the metal to
the mould.

page_text: In some cases I use a blow pipe, instead of a furnace, to render the metal
pliable.
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 :-
The application of heat to metals while manipulating the saune, substantially as
and for the purposes herein before described, and illustrated by the drawings.
