PROVISIONAL SPECIFICATION.
Improvement in Fastenings for Traces, Chains, and the like.
ARTHUR LAMPLOUGH Gentleman 2 Finsbury Square E.C. do hereby declare
the nature of this invention to be as follows:-
It consists of a flattened link made of iron or any other suitable metal
2 inches more or less in length with a cavity inch more or less in width cut
at one end of the link-this end of the link being at right angles & straight-
over this cavity a steel spring is placed 2 inches more or less in length-but
made to turn on a screw or bolt-the other end of this spring is made to fit
into a slot in the straight part of the link when in use.
The object of this simple device is that in case of need the spring can be
instantly pulled back and the trace chain unlinked-thus setting the fallen horse
free.
This connecting link can be applied to any chains where coupling purposes are
needed.
Dated this 30th day of April 1891.

COMPLETE SPECIFICATION.
Improvement in Fastenings for Traces, Chains, and the like.
I ARTHUR LAMPLOUGH of No. 2 Finsbury Square in the County of London
Gentleman 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 detachable links employed for coupling and uncoupling
chains for any purpose where it is necessary to disconnect a length of chain. My
improvement is especially applicable to cases where the chain requires to be
uncoupled while subject to strain such as in the case of uncoupling a trace strained
by a fallen horse.
I make the detachable link in iron or any other suitable metal having an opening
in one of its longest walls at the end adjoining the end wall which projects at right
angles from the other of its longest walls. This opening serves as a passage for
admitting or withdrawing one or both of the end links of the chains to be coupled.
The opening is closed or opened as required by means of a spring clip hereinafter
more fully described by reference to the accompanying drawings in which
Figure 1 is a plan of my improved detachable link closed by the spring clip.
Figure 2 is a plan of the same showing the spring clip opened.
Figure 3 is an end view of Figure 1.
Figure 4 is an edge view of Figure 1.
I make the detachable link A in the flattened form shown by Figures 1 and 3
providing an opening at B adjoining the end wall C of the link which projects from
the longest wall of the link at right angles in order that a link may be admitted or
withdrawn through the opening B while the chain to be disconnected is subjected
to strain.
By means of a screw or bolt DI pivot upon the flattened link A a spring clip E
The lip F
stamped from a flat piece of sheet steel to form the lips F G thereon.
serves to lock the spring clip E in position by entering the saw cut H made in the
end wall C and the lip G abutting upon the side of the link prevents the spring
clip E from being pushed beyond the point at which the lip F will enter the saw
[Prins 6d1

of the links when closed.
Having now particularly described and ascertained the nature of my said
invention and in what manner the saine is to be performed, I declare that what
I claim is :-
11
A detachable link; for uniting and disuniting chains, consisting of a link having
an opening therein closed when required by a spring clip substantially as described
and shown by the accompanying drawing.
