Improved Construction of Links for Chains.
I, OTTO KLATTE, Manager of the Firm Walzwerk, Germania, Neuwied on the
Rhine, Germany, 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 present invention consists in forming chain links of one or more wires of any.
desired thickness or of such wires twisted to form a rope, said links being formed
by winding the wire, wires, wire rope, or wire ropes in the form of a chain link
and suitably splicing in the ends to prevent their becoming detached.
As wire of any strength may be employed for this purpose it is obvious that
chains of any desired strength can be attained according to the present invention.
Links of this kind are particularly adapted for forming very strong chains, and for
connecting the ends of weldless chains. Links formed of wire may be wholly or
partially covered with thinner wire in order to ensure the retention of the circular
section of such link, when the chain is under tension. Or the link may be enclosed
or partly so in a metallic casing which may either be cast round the said link, or
may consist of an open metallic casing into which the wire forming the said link
may be wound and then the casing closed onto the same such metallic casing being
whole or divided.
And in order to make the present invention more easily intelligible reference is
had to the accompanying drawings in which the similar letters denote similar parts
throughout the several views :-
Figure 1 being a side elevation partly in section of a part of a chain formed of
wire and provided with an undivided metallic casing.
Figure 2 a plan of Figure 1.
Figure 3 is a similar elevation to that of Figure 1 showing link or wire rope
having a metallic casing with overlapping joints, and
Figure 4 is a plan of Figure 3 with the casing partly removed.
Referring to Figures 1 and 2, the link proper is formed of wire a suitably wound
and bound within the open metallic casing b which is advantageously thicker at the
interior of the said link, and tapering towards the edges. This casing is advan-
tageously formed in two parts, having tapering ends overlapping at cc and suitably
connected together. This casing is split around the exterior sides of the link and
before closing, the ends d appear as shown in dotted lines in Figure 1.
closed the ends d d of the casing are folded down and form a butt joint as shown
in full lines at Figure 1.
When
Figures 3 and 4 show a chain link formed of wire rope a and also having a
casing divided somewhat differently as shown at cc the ends of the casing overlapping
whilst in this case the horizontal seam of the casing does not butt, but overlaps as
shown at Figure 3.
The advantage of chain links formed in this manner with an exterior casing is
that when the casing is worn, the same can easily be removed and a new one
substituted.
It will be evident that for the purposes of this invention wire and wire rope are
substantially the same, and that may also provide the interior wire with a casing
or covering of a thinner kind of wire instead of metal.

page_text: 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. A chain link formed of wound or twisted wire having the ends suitably spliced
substantially as described.
2. The combination of a chain link formed of wound or twisted wire and enclosed
in a suitable casing substantially as described.
3. The combination of a chain link formed of wound or twisted wire and a
divided casing to enclose the same, substantially as described.
4. The combination of a chain formed of wound or twisted wire and having a
metallic casing, said casing being divided and having its ends overlapping at the
joints, substantially as described.
5. The combination of a chain link formed of wire a, a casing b enclosing said
wire a, and having its ends d tapered at the juncture c, for overlapping, substantially
as described.
