PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Squirting Metals in a Heated
Condition.
We, FREDERICK GEORGE PANIZZI PRESTON, of the Firm of J. Stone & Com-
pany, of Deptford, in the County of Kent, Engineers, and JAMES SHAW MCLAREN,
in the employ of the said firm, do hereby declare the nature of this invention
to be as follows:-
Our invention relates to apparatus for squirting metals in a heated condition
and it has principally for object to construct a so called "container" for the
heated metal to be operated on, which will stand a considerable
variation of temperature without bursting or becoming deform...
essure and
According to our invention the cylinder or container for containing the heated
metal consists of a comparatively thin tube or lining of steel or the like and
around this tube we wind comparatively thin wire of a flat or other suitable
section in several layers, the ends of which wire are fastened in any convenient
manner either to the tube or independently of the tube. The tension given
to the different layers of the wire windings may vary according to the alteration
of diameter of the container as it is being built up, that is to say the first layer
of winding may be done with a greater tensile strain on the wire than the next
layer and so on.
The container may then be enclosed in an outer casing or belt provided with
trunnions if desired and it has a plunger which is actuated by a hydraulic ram
or other suitable means. The apparatus is further provided with a die of any
approved construction which is so made as to be removable or adjustable and
if the apparatus be used for making tubes or similar hollow articles we provide
a suitable mandril. It is evident that various sizes and shapes of dies and
mandrils are used for forming articles of different kinds.

Improvements in Apparatus for Squirting Metals in a Heated
Condition.
We, FREDERICK GEORGE PANIZZI PRESTON, of the Firm of J. Stone & Com-
pany, of Deptford, in the County of Kent, Engineers, and JAMES SHAW MCLAREN,
in the employ of the said firm; do hereby declare the nature of this invention

page_text: 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 apparatus for squirting metals in a heated condition
and it has principally for object to construct a so called "container" for the
heated metal to be operated on, which container will stand a considerable pres-
sure and variation of temperature without bursting or becoming deformed.
According to our invention the cylinder or container for containing the heated
metal consists of a comparatively thin tube or lining of steel or the like and
around this tube we wind comparatively thin wire of a flat or other suitable
section in several layers, the ends of which wire are fastened in any convenient
manner. A suitable thickness is of an inch and of an inch wide but we
do not limit ourselves in any way to these dimensions. The tension given to
the different layers of wire windings may vary according to the alteration of
diameter of the container as it is being built up, that is to say the first layer
of winding may be done with a greater tensile strain on the wire than the
next layer and so on, as practised in the manufacture of wire-wound guns.
As an example we may state that the first layer or layers of wire may be
wound at a tension of say 50 tons per square inch and the last layer or layers
at say 25 tons but we do not limit ourselves to these figures as they may be
varied without departing from our invention.
The container may then be enclosed in an outer casing or belt provided with
trunnions if desired and it also has a plunger which is actuated by a hydraulic ram
or other suitable means. The apparatus is further provided with a die of any
approved construction which is so made as to be removable or adjustable and
if the apparatus be used for making tubes or similar hollow articles we provide
a suitable mandril. It is evident that various sizes and shapes of dies and
mandrils are used for forming articles of different kinds.
Figure 1 of the accompanying drawings represents in sectional elevation a
container constructed according to our invention.
Figure 2 is an end view thereof.
Figure 3 is a detail view in transverse section showing a convenient mode of
fastening the wire.
Figures 4, 5 and 6 show slightly modified forms in sectional elevation.
Referring to Figures 1 and 2 the cylinder or container for containing the
heated metal consists of a comparatively thin tube or lining a of steel or the
like and around this lining we wind comparatively thin wire b of a flat or other
suitable section in several layers as indicated the ends of which wire are fastened
for example as shown that is to say the inner end is clamped in the lining a as
shown in Figure 3 by the head of a screw the top of which is flush with the
said lining and preferably a washer is interposed between the head of the screw
and the end of the wire. The other or outer end of the wire b may also be
clamped as shown in Figure 3 to one of two discs g attached to the lining a
by screws h by which discs the wire is also kept in place. The whole may be
protected by an outer casing e, which is made in halves bolted together by
bolts d and to which the dises 9 may be also attached by screws h.
instead of there being two lugs for each half part of the casing there may be
more or each casing part may have two flanges extending the whole length
of the container. Or the wire may be fastened at each end in any other con-
venient manner. As aforesaid the tension given to the different layers of the
wire windings varies. Instead of using wire we may use thin sheet metal of
any convenient width to wrap round the lining practically in the same manner
as has been described with reference to the wire. The outer casing e is pro-
vided if desired with trunnions f f see Figure 2 and it has as usual a plunger
(not shown) which is actuated by a hydraulic ram or other suitable means.
The apparatus is further provided with a die as aforesaid or a die and a man-
dril according to the articles it is desired to produce.
Or

page_text: Figure 4 represents a container in which the lining is mounted in another
tube a to which the inner end of the wire is fastened independently of the
lining a.
Figure 5 represents a slightly modified form in which the wire b is replaced
by rings 6 of wrought iron or other suitable metal to form several layers which
are shrunk on to the lining a, so as to be in tension.
Figure 6 shows yet another modification in which the wire is replaced by a
number of concentric cylinders or tubes 62 of wrought iron or the like to form
several layers which are shrunk on to the lining a, so as to be in tension.
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:-
1. A container for squirting metals in a heated condition consisting of a lining
surrounded by a number of layers of wire.
2. A container for squirting metals in a heated condition consisting of a
lining surrounded by wrappings of thin metal.
3. A container for squirting metals in a heated condition consisting of a
lining surrounded by a number of layers of rings or tubes substantially as set
forth.
4. A container for squirting metals in a heated condition consisting of a lining
surrounded by a number of layers of wire or sheet metal, having a greater
tension during winding near the lining than at a distance therefrom substan-
tially as set forth.
5. The constructions of containers for squirting metals in a heated condition
as described and shown on the drawings.
