Improvements in or connected with the Manufacture of Chain Cables.
I, JOHN VERITY, of 15, Lidderdale Road, Liverpool, in the County of Lan-
caster, Engineer, do hereby declare the nature of this invention to be as follows:-
-
This invention has reference to the manufacture of chain cables, or chains,
more particularly of cast steel, and, more especially, those kinds which are used
on board ship, as anchor cables, mooring cables, and the like; and it has for its
object to provide improvements in connection with that method or mode of mak-
ing chain or cables, wherein steel links are cast through another or other links,
which are already made, or partly made, by which this method can be more
expeditiously carried out, and links and chains more rapidly made than hereto-
fore, and generally to simplify and expedite the manufacture, and render the
manufacture capable of being practically and successfully carried out, at a low
cost.
According to this invention, separate links of steel are first manufactured by
casting, and then these separately manufactured links, in pairs or groups, are
joined together by casting other steel links through them, that is, through the
adjacent ends of the two links which become so coupled together. This is
effected, under the present invention, by the employment of mechanical casting
boxes, containing comparatively thin and light moulds, or linings of sand, or
the like, for forming the sides and greater part of the connecting-up link, and of
employing separate sand mould pieces for the sections for making the parts of
the connecting up link which pass through the links to be connected; and the
already cast links to be coupled up, are adapted to serve as a means of holding
these parts of the moulds. The side sand moulds or linings, held in the casting
boxes, together with the moulds held by the links, make a complete mould for
the link. The side moulds or linings are placed and held in the mechanical
moulding box, their ends being a certain distance apart and the manufactured
links, holding the moulds for the end portions, are introduced into the casting
box from either side, and are held there during the casting operation.
As regards the metallic casting box, this may advantageously be of the type
set forth in the Specification of my former Letters Patent No. 14242 of 1896,
with moveable parts, and seats or chambers for holding the sand moulds or
linings, and gaps for receiving and holding the links.
Each part or half of the said moulds or linings for the casting box will be
conveniently made in halves which fit one on the other.
The links made as described, are preferably cast in circular, or substantially
circular. form: whilst the other links which they connect up. and are cast
through, are complete links: and, when of the stud link type. are already fitted
with the stud in position. Or, as a modified method of manufacture, the links
which are to be connected up by casting other links through them, are, first,
only partly made, and of circular form: that is, they consist of plain cast steel
rings: then the connecting up rings are cast through them: and then afterwards,

Improvements in or connected with the Manufacture of Chain Cables,
I, JOHN VERITY, of 15. Lidderdale Road, Liverpool, in the County of Lan-
caster, Engineer, do hereby declare the nature of this invention, and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement;-
-
This invention has reference to the manufacture of chain cables or chains,
more particularly of cast steel, and, more especially, those kinds which are used
on board ship. as anchor cables, mooring cables, and the like; and it has for its
object to provide improvements in connection with that method or mode of
making chain or cables, wherein steel links are cast through another or like
links, which are already made, or partly made, by which this method can be
more expeditiously carried out and links and chains more rapidly made than
heretofore, and generally to simplify and expedite the manufacture, and render
the manufacture capable of being practically and successfully carried out, at a
low cost.
According to this invention, separate links of steel are first manufactured by
casting, and then these separately manufactured links, in pairs or groups, are
joined together by casting other steel links through them, that is, through the
adjacent ends of the two links which become so coupled together. This is effected,
under the present invention, by the employment of mechanical casting boxes,
containing comparatively thin and light moulds, or linings of sand, or the like,
for forming the sides and greater part of the connecting-up link, and of employ-
ing separate sand mould pieces for the sections for making the parts of the con-
necting up link which pass through the links to be connected: and the already
cast links to be coupled up, are adapted to serve as a means of holding these
parts of the moulds. The side sand moulds or linings, held in the casting boxes.
together with the moulds held by the links, make a complete sand mould for
the link. The side moulds or linings are placed and held in the mechanical
moulding box, their ends being a certain distance apart and the manufactured
links, holding the moulds for the end portions, are introduced into the casting
box from either side, and are held there during the casting operation.
As regards the metallic casting box, this may be advantageously be of the type
set forth in the Specification of my former Letters Patent No. 14242 of 1896,
with movable parts, and seats or chambers for holding the sand moulds or
linings, and gaps for receiving and holding the links. "Each part or half of
the said moulds or linings for the casting box will be conveniently made in halves,
which fit one on the other.
Drawings illustrating this invention are hereto annexed. In these drawings.
Figure 1 is an elevation partly in section, shewing the boxes and completed
links placed in position ready for the casting operation: and Figure 2 is a plan
view, taken through the line A A Figure 1. Figure 3 is a side elevation
in

page_text: In the drawings, a generally designates the casting boxes containing the light
sand moulds; and are the finished links into which other connecting links are
to be cast.
The mould shewn comprises the back or body b, with the central longitudinal
gap in it; and the two covers e el, fitting on the parts above and below the
gap b, respectively, and held to the body by pins d. At the upper part of
the body in the cover c, a runner c, lined with a sand mould or lining e', is
provided, through which the molten metal is run into the upper of the sand
moulds on either side of the gap b. The body, and covers ce, are provided
with semi-circular or nearly semi-circular chambers; and into these chambers
the sand linings or moulds are placed. Each mould is a hollow semi-annulus,
made in halves in the direction of its plane, and fitting respectively in the body,
and covers of the box.
Regarding the finished links. these are provided with a sand mould at
each end, the sides of which are substantially Hush with the sides of the link:
and these moulds will have a hole through them, which, when a link is placed
in position, must be coincident with the ends of the hole of the sand moulds h.
These moulds of the finished links are shewn clearly in Figures 1 and 2,
where the link shown is one having a stud . The sand mould, in this case,
extends from end to end of the space within the link, and surrounds the stud o'.
It will now be seen, that when the sand moulds or linings are in position,
in the boxes a, with the links o in position in the gap on each side, containing
their sand moulds p. a complete hollow circular sand-mould is provided extending
through the completed links o at either side. Consequently when the metal is
run into the box a through the sand lined runner e. and Hows into and round
the circular space through the moulds hand p. it casts a complete ring or link
through the two finished links o in the box, joining the two up.
If several boxes a be placed a side by side, with the links o joined up with
them as described, and in the correct relative positions, several links may be
cast in succession or together, and a considerable length of chain made in one
casting operation.
Of course, after the casting operation, when the metal is sufficiently cool,
the covers ee of the box are taken off, and the links forming a length of cable,
taken out.
Thus while the moulding or casting operation is what may be termed a
"mechanical casting or moulding, yet all the castings are in effect, or equiva-
lent to sand castings" and possess the required qualities and characteristics.
The links made as described, are preferably cast in circular, or substantially,
circular, form: whilst the other links which they connect up, and are cast through,
are complete links, and, when of the stud link type, are already fitted with the
stud in position. Or, as a modified method of manufacture, the links which are
to be connected up by casting other links through them, are, first, only partly
made, and of circular form: that is, they consist of plain cast steel rings; then
the connecting up rings are cast through them: and then afterwards, all the links
are heated up, and bent to the required form, fitted with the studs, and finished.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
1. The herein described improvement in or connected with the manufacture of
chain cables, namely, the manufacture of such cables wherein links are cast into
or through completely or partly manufactured links, and part of the moulds to
receive the casting metal are sand moulds held within or by said completely or
partly manufactured links: the other parts of the said moulds being held in
boxes: for the purposes set forth.
2. In the manufacture of chain cables wherein links are cast into or through
completely or partly manufactured links, the employment of mechanical casting boxes

page_text: in which sand linings or moulds are used and arranged on either side of the
said manufactured links: and sand moulds within the said links between said
box moulds; said boxes and links being arranged relatively to each other as set
forth substantially as described.
3. The apparatus or means for manufacturing chain cables, constructed and
arranged particularly as shewn in, and set forth with reference to the drawings.
