I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent:
Agents, do hereby declare the nature of this Invention (a communication to me
from abroad by William H. Clay of Paris in the County of Bourbon and State of
Kentucky United States of America) 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 a split link in the nature of a "match hook" adapted.
to secure one length of a chain to another and for other uses. .The link consists of
two halves hinged together at one end and folding together. so as to form a
complete link. Each half is made of half round iron with an opening in one of
its sides and an enlargement or protuberance at its opposite side, the opening in
one half of the link receiving the enlargement on the other when the link is closed.
and thus forming a complete and continuous link. The ends of each half of the
link opposite to the hinge is cut away.so that when the link is closed a V shaped
recess will be formed in the link thus enabling the link to be opened by inserting
a nail & in the recess should the two parts stick together.
In one form of link the ends of the enlargements or protuberances are bevelled.
and the ends of each half of the link at the openings are oppositely bevelled so na
to form tight joints when the link is closed. The one end of each half is formed.
with corresponding projections to form the knuckles for the hinge. In another
form the projections are omitted and the hinge is formed in the material composing
the body of the link, and in this link the ends of the projections are cut diagonal
to the line or plane of the hinge and the ends of the parts of the link that close.
against the projection are cut to an opposite angle to fit the diagonal ends of the.
projections and lateral movement of the halves of the link upon each other and.
strain on the hinge will be avoided.
By constructing the link with the hinge arranged as shown and described the.
small flanges or tins of metal which always form at the inner edges of the parts of.
the link in the use and wear thereof, in no manner interfere with the opening
of the link, as such fins do with links that open and close edgwise with the parts of
the link sliding upon each other.

"match-hook" for
This Invention relates to a "split-link" in the nature of a
securing one length of chain to another, and for other uses; and the Invention
consists in the peculiar construction and arrangement of parts, as hereinafter fully
described and pointed out in the claim.
Reference is to be had to the accompanying drawings forming part of this
specification, in which figure 1 is a plan view of the new and improved link as it
appears when closed. Figure 2 is a sectional elevation of the same taken on the
line xx of figure 1. Figure 3 is a plan view of the link as it appears when open.
Figure 4 is a sectional elevation of the link taken on the line y y of figure 1.
Figures 5 and 6 are plan and sectional views shewing the link formed with
diagonal protuberances, and figure 7 is a side view shewing the link open.
Similar letters of reference indicate corresponding parts in all the figures.
A represents the new and improved link. This is composed of two parts ab
hinged together by the hinge c. The part a is for the most part made of half-
round iron. It is open at a cut away at as and formed upon its inner surface,
opposite the opening a¹, with the enlargement or protuberance a³. The part 6 of
the link, like the part a, is for the most part made of half-round iron. It is open
at 6 cut away at 6' and formed upon its inner surface, opposite the opening 61
with the enlargement or protuberance bª. The opening a¹ of part a stands at the
opposite side of the link from the opening b¹ of part 6, and the enlargement a³ of
part a stands at the opposite side of the enlargement 63 of part b, so that when the
parts ab of the link are closed together, the enlargements a b³ close the
openings a¹ b¹ and thus form a complete and continuous link, as shewn in figures 1
and 2. The cut-away places a 6' when the parts of the link are closed together,
form a V-shaped recess, as shewn in figure 2, so that a nail, or other small object,
may be easily inserted between the parts of the link for forcing it open in case it
should stick or not work easily at the hinge.
In the form of link shewn in figures 1, 2, 3, and 4, ends of the enlargements or
protuberances as b³ are bevelled as shewn at d and the ends of the parts of the
link at the openings a¹ b¹ are oppositely bevelled as shown at d¹ to fit the bevelled
ends of the enlargements or protuberances, as clearly shown in figure 2, so that
tight joints will be formed at the openings in the parts of the link when the link
is closed, and in this form of link corresponding projections c¹ are formed on the
parts a b of the link which are fashioned to form the hinge c
In the form of link shewn in figures 5, 6, and 7, the projections c¹ are omitted,
the hinge c being formed in the material composing the body of the link, and in

page_text: this form of link the ends of projections a³ 63 are cut diagonal to the line or plane
of the hinge c and the ends of the parts of the link that close against the pro-
jections or protuberances are cut at an opposite angle to fit the diagonal ends of
the projections, as shewn clearly in figures 5 and 6, 'so that the projections will
prevent lateral movement of the parts of the link upon each other, and thus
prevent strain upon the hinge c.
By constructing the link with the hinge arranged as shewn and described, the
small flanges or fins of metal which always form at the inner edges of the parts
of the link in the use and wear thereof in no manner interfere with the opening of
the link, as such fins do with links that open and close edgewise with the parts of
the link sliding upon each other.
Having now particularly described and ascertained the nature of the said
Invention, and in what manner the same is to be performed I declare that what
I claim is;-
A link, consisting of the parts a b hinged together at the end to open away from
each other, and each provided on its inner surface with an enlargement or pro-
tuberance and an opening to receive the enlargement or protuberance, substantially
as herein shewn and described.
