Improvements in the Manufacture of Chains.
1, WILLIAM EDWIN HEYS, of 70 Market Street, Manchester in the County
of Lancaster, Patent Agent, do hereby declare the nature of this invention to be
as follows:-
Hitherto, the links of chains, and more especially of heavy chains, have generally
been forged or stamped out and the links closed by welding.
According to this invention, the chain is produced by casting from suitable
metals such as steel, bronzes, and the like, as hereinafter described with reference
to the accompanying drawings.
By this method, the welding is dispensed with so that chains of any form may
be cheaply made with the material so distributed that it can have greater dimensions.
where the friction is greatest.
The form of chain illustrated, whilst it is difficult to construct by ordinary
processes, can be as easily manufactured as one with a plain link, but it will be
understood that this invention is not limited to chains having a stay such as c in.
each link or in any link.
In constructing a chain according to these improvements, two or more links a are
cast together in a suitable mould.
These cast links a are then arranged at proper distances apart in another mould,
so that the matrixes for the intervening link or links may not be in contact, and
these intervening links are then cast with their loops din engagement with the
similar loops of the first links.
By this means, a long or short chain can be made at one operation by casting
one or more of the desired number of links bin engagement with links a, and on
being taken from the mould the chain will be complete.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Chains.
I, WILLIAM EDWIN HEYS of 70 Market Street, Manchester, in the County of
Lancaster, Patent Agent, 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 :-
This invention relates to the manufacture of chains by casting.
Hitherto the links of chains, and more especially of heavy chains, have generally.
been forged or stamped out, and the links closed by welding.
By this improved method of manufacture a chain is produced by casting from
suitable metals such as steel, bronzes, and the like, thus dispensing with welding
[Price 811

page_text: and its attendant disadvantages. A chain may thus be cheaply made with the
material so distributed as to have its greatest dimensions where the friction is
greatest.
The accompanying drawings to which reference is hereinafter made illustrate
three links of a chain constructed according to this invention.
The form of chain illustrated, whilst it is difficult to construct by ordinary
processes, can be as easily manufactured as one with a plain link, but it will be
understood that this invention is not limited to chains having a stay such as e in
each link or in any link, and that the links may be of any desired form.
In carrying this invention into effect certain of the links a are first cast
separately and are then arranged at proper distances apart in another mould in
which are formed the matrices for the intervening links b. These matrices are so
formed and the links a are so placed that when the intervening links bare cast
their loops are in engagement with the similar loops of the links a.
By this means a long or a short chain can be made at one operation by casting
one or more links b in engagement with links a, and on being taken out of the mould
the chain will be complete.
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 -
-:
1. In the manufacture of chains, casting certain of the links in engagement with
other previously formed links, substantially as herein before described and as
illustrated by the accompanying drawings.
2. A chain constructed substantially as herein before described and as illustrated
by the accompanying drawings.
Dated this 12th day of June 1896.
