PROVISIONAL SPECIFICATION.
Improvements in the Links of Chains or Cables, and in the Method
or Means of Making the same.
We ISAIAH HAMPSON of 27 Milner Road Hillsborough Sheffield in the County
of York, Smith, and WILLIAM HENRY BAGNALL of 19 Wood Street Langsett Road
Sheffield Spring Finisher do hereby declare the nature of this invention to be as
follows:-
Our invention relates to and consists in making links of chains or cables perfectly
solid one with the other instead of their having to be welded or joined or pieced when
put together as heretofore.
In making our improved links, which are composed of steel or other suitable metal,
we employ a sufficient number of moulds according to the length of chain or cable
required to be made. We prefer to make the moulds of strong cast iron; or other
sufficiently strong metal or compound of metals can be used if desired.
The moulds are made in two main portions, that is, an upper and an under portion ;
both upper and under portions are made in two pieces, (or more if necessary); each
portion is grooved or hollowed out into the shape the links are required to be
made, that is, either oval or circular, or of other desired shape, and a hole is made in
the centre of each portion of the mould sufficiently large for the link to pass through
after being moulded or cast.
The moulten steel or other suitable metal is run into the grooved or hollowed out
portions in the usual way, by suitable inlets made in the moulds, the upper and lower
moulds being fastened or secured together by pins or cotters. When cool enough
the moulds are opened out, whereupon a complete solid link will be found which will
require neither welding nor joining together in any part. The two portions of the
upper and under moulds are then, as it were, reversed, or turned over one on the top
of the other and fastened or secured together leaving the made link loose and
suspended in the hole made in the centre of the mould. The moulten steel or other
metal is then run into the grooved or hollowed out portions of the mould, but leaving
the made link suspended in the hole in the centre; and thus another solid link is
made having the first made link hanging, as it were, in its centre.
This mode of manufacture is repeated in making each succeeding link.
Our said invention, and the mode of carrying it out in practice, can be advan-
tageously adopted in making the links of all kinds of chains or cables whether of large
or of small sizes.

COMPLETE SPECIFICATION.
Improvements in the Links of Chains or Cables, and in the Method
or Means of Making the same.
We ISAIAH HAMPSON of 27 Milner Road Hillsborough Sheffield in the County
of York Smith, and WILLIAM HENRY BAGNALL of 19 Wood Street Langsett Road
Sheffield Spring Finisher 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 in writing, and on reference to the accompanying
sheet of drawings:-
Our invention relates to and consists in making links of chains or cables perfectly

page_text: solid one with the other, instead of their having to be welded or joined or pieced when
being put together or interlinked, as heretofore.
In making or casting our improved links, which are composed of steel or other
suitable metal, we employ a sufficient number of moulds according to the length of
chain or cable required, and the moulds we prefer to make of strong cast iron, or
other sufficiently strong and suitable metal, or a compound of metals can be used
therefor if desired.
In order however that our improvements, and the means we adopt in carrying out
our invention in practice may be fully understood, we have illustrated the same on
the accompanying sheet of explanatory drawings, marked with figures and letters of
reference corresponding with those in the following description, the same reference
letters indicating like parts in all the figures.
Figure 1, is a front elevation of half a mould, the other half being made to
correspond.
Figure 2, is a section drawn on the line A-B in Figure 1.
Figure 3, is a top view of the mould complete.
Figure 4, is a side view of the mould showing a solid link as hanging in the hole
in the mould during the making or casting of a second link, and,
Figure 5, is a front view of a mould as constructed for making or casting
cable links.
The moulds are made in two main portions, that is, consisting of an upper and an
under portion a, and b, as shown at Figures 2, and 3.
Both the upper and the under portions are made in two pieces c, and d, as shown
at Figures 1, and 4; or they can be made in more pieces or parts if found necessary.
Each portion of the mould is grooved or hollowed out (at e, Figures 1, 2, 4 and 5,)
into the shape the links, such as that shown at g, Figure 4, are required to be made
or cast; it being understood that our links can be made or cast either of an oval
circular or other desired shape, the grooves being of course shaped to correspond.
A hole , is made in the centre of each portion of the mould sufficiently large for
a link to be passed through after being moulded or cast.
The moulten steel or other metal is, in the usual manner,-run into the grooved or
hollowed out portions e, by inlets i, made in the moulds, the upper and under
moulds a, b, having been first fastened or secured together by pins or cotters j, k, or
by other like means.
When the steel or other metal has become cool enough the pins or cotters are
withdrawn and the moulds are opened out whereupon a completely solid link will be
found made, which will not require any welding or joining together in any part as
according to the old process of manufacturing links.
The two portions of the upper and under moulds a, and b, are then reversed, or
turned or folded over so as to be one on the top of the other, they are then fastened
or secured together by a cotter or other convenient holding means, and the made
link will be loose and hang suspended in the hole h, in the centre of the mould, as
seen in Figure 4.
Moulten steel or other metal is again run into the grooved or hollowed out portions
of the mould as before, the made link g, remaining suspended as just mentioned, and
in this manner another solid link is made or cast the second made link hanging loose
from the centre of the first made link.
This improved mode of manufacturing the links is repeated as often as necessary
in the making or casting of each succeeding link, according to the length of chain
or cable required to be made.
The moulds we employ in making or casting the studded links of cables, instead of
being divided as shown at A-B Figure 1, are divided lengthwise down the middle
as shown at CD Figure 5, and the grooves therein are so cut or shaped as to
mould and turn out the links with the studs therein perfectly solid, f, being the stud
in the link g, as seen in Figure 5.
It will be evident to the practical chain manufacturer that our said invention and
the mode of carrying it out in practice can be advantageously adopted in making or

page_text: casting the links of all kinds of chains or cables and either of large or small sizes or
shapes.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is: -
1. The making or casting of links of chains or cables perfectly solid one with
another, instead of welding joining or piecing the links when being put together
to form chains or cables, substantially in the manner hereinbefore set forth; and
2. The novel and peculiar construction, arrangement, and manipulation of moulds
for making or casting links of chains or cables solid, substantially as hereinbefore
described and as illustrated on the accompanying sheet of drawings.
