Improvements in or connected with Chill-moulds for Casting
Cylinders with Side Connections.
We, THOMAS GARFORTH RHODES, of Albert Terrace, Kirkstall, Leeds, Engineer,
and RAYMOND GAUNT, of The Mount, Stanningley, near Leeds, Engineer, both in
the County of York, do hereby declare the nature of this invention to be, as
follows:
-
The object of our invention, is to construct apparatus whereby cylinders having
side bends or connections, may be. cast without the necessity of employing sand
cores, thus forming the said cylinders in a smoother and more efficient manner
than heretofore.
The
According to our invention, we provide an exterior mould of, the external shape
of the cylinder and bent connection which it is desired to form, and within the
main portion of the mould we provide a central core which is held in position by a
spindle passing through the outer mould and into the centre of the main core.
core of the bend is supported in the external mould, and between the main core
and the bend core, an intermediate piece is provided which is connected to the said
main and bend cores in such a manner, that they may be released from the inter-
mediate piece by being withdrawn longitudinally from their positions in the main
mould. The intermediate piece is of such a form that, it may be released from the
casting into the interior of the cylinder, after the withdrawal of the main and pipe
cores. A suitable way of connecting the intermediate piece to the cores, is by
forming a recess in the said intermediate piece for the reception of the end of the
auxiliary core, and by forming the intermediate piece with dovetailed projections
which tako into dovetailed recesses in the side of the main core.

We, THOMAS GARFORTH RHODES, of Albert Torrace, Kirkstall, Leeds, Engineer,
and RAYMOND GAUNT, of The Mount, Stanningley, near Leeds, Engineor, both in
the County of York, 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:
The object of our invention is to construct apparatus whereby cylinders having

page_text: side bends or connections, may be cast without the necessity of employing sand
cores, thus forming the said cylinders in a smoother and more efficient manner
than heretofore.
In order that our invention may be clearly understood we will proceed to describe
same with reference to the accompanying drawing, in which similar letters refer
to like parts in all the figures.
Figure 1 shows the interior of one half of the chill-mould with the cores removed,
and Figure 2 is a similar view of the chill-mould shewing the cores in position.
Figures 3, 4 and 5 are detail views.
According to our invention, A is a chill-mould, composed of two halves the
interior of which when the parts of the mould are together being of the external
shape of the cylinder B and bent connection C which it is desired to form, and
D is a central core which is held in position by a spindle E, which rests in a recess F
in the outer mould A. G is the core of the bend which is supported in the neck H
of the external mould A, and J is an intermediate piece which is supported in
position by a screw K situated on the end of the core G, and by dovetailed pro-
jections L which slide in slots M in the core D. The intermediate piece J is of a
taper form, diminishing in diameter in all directions until it embraces the main
core G.
When making cylinders with side connections in the moulds above described,
the cores D and G, together with the intermediate piece J are placed in position,
and after the mould has been closed, the metal is poured and allowed to stand in
the ordinary way. When the metal is set, the cores D and G are withdrawn,
leaving the intermediate piece J within the casting, from which, owing to its taper
form, the said piece J may be removed through the main interior, as scen at Figure 5.
The cores D and G may be connected to the intermediate piece J by any other
means than those abovo described, providing they permit of the withdrawal of the
said cores in a longitudinal direction, and the said intermediate piece may be of
any form so long as it tapers toward the interior of the mould.
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. The intermediato piece J, substantially as and for the purposes set forth.
2. The intermediate picco J, held in position by the cores D and G, substantially
as and for the purposes set forth.
3. The combination with the mould A, of the centro core D having slote M, the
intermediate piece J having dovetailed projections L, and the core G having a
screw K, substantially as and for the purposes sot forth.
