Improvements in Chain Attachments.
I, HERBERT JOHN ALLISON, of 52 Chancery Lane, London, in the County of
Middlesex, Patent Agent, do hereby declare the nature of this invention, which
has been communicated to me from abroad by The Bridgeport Chain Company, a
corporation located at Bridgeport, Fairfield County, Connecticut, U.S.A., and in what
manner the same is to be performed to be particularly described and ascertained in
and by the following statement :-
My invention relates to the various classes of short chains which have gone into
extensive use and are now manufactured and sold as independent articles as, for
example, balter chains, kennel chains etc. and has for its object to provide a novel loop
and bar therefor which shall greatly increase the efficiency in use leaving all parts of
the chain amply strong for every purpose to which it can be applied, which shall give
to the chain a neat and attractive appearance, and in which the cost of production
shall be reduced to the minimum.
With these ends in view, I have devised the novel attachments of which the following
description, in connection with the accompanying drawing, is a specification, numbers
being used to denote the several parts.
novel chains ;
Fig. 1 is a view of one end of one of my
Figs. 2 and 3 views illustrating the construction of the cross bar and the manner in
which it is attached to the chain;
Fig. 4, a view of the loop detached; and
Fig. 5 is a perspective showing the loop connected to a chain link as in use.
The chain forms no portion of my present invention it being of course apparent,
that any suitable chain may be used, althongh in practice I preferably use, and have
illustrated in the drawing, the chain covered by British letters patent No. 11,598
A.D. 1887.
1 denotes the chain, and 2, the cross bar. This cross bar is struck out from sheet
metal. It is made widest at the middle as shown, and an opening 3 is punched out at
the widest portion, care being taken, however, to leave sufficient metal upon the inner
side of the bar to resist any possible strain. Upon the outer side of the bar is a cut 4
leading into the opening. The operation of attaching the bar to the chain is clearly
illustrated in Figs. 2 and 3; the metal on opposite sides of the cut is pressed outward
in opposite directions as shown in Fig. 2. One end of the bar is then passed through
the opening in the end link of the chain and the end of the link itself dropped into the
opening 3 in the cross bar. The metal of the bar is then closed together as shown
in Fig. 3 leaving the bar firmly connected to the last link of the chain. Operating in
connection with this cross bar is a loop 5, see Figs. 1 and 4. This loop is provided
with an eye 6 at each end which incloses the opposite sides of the link of the chain.
In practice, the ends of the eyes are opened outward, the sides of the chain link to
which it is desired to attach the loop are placed in the eyes, and the ends of the loop
closed around the sides of the chain link, leaving the loop, however, free to swing on
the chain. This feature of connecting both ends of the loop with the opposite sides of
a link of the chain is an important feature in use as it retains the loop in convenient
position to receive the cross bar and prevents it from turning in every direction as
when an ordinary ring is used. At the other end of the chain, in practice, I place a
snap hook which may be of any suitable or preferred construction.
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. The combination with a chain link, of a loop having eyes at opposite ends which

page_text: engage the opposite sides of the link, thereby securing both ends of the loop firmly to
the chain, leaving the loop free to swing, and a cross bar connected to the chain and
adapted to engage said loop.
2. A sheet metal cross bar for chains made widest at its central portion and
having a central opening with a cut leading thereto from the outer edge of the bar, so
that the metal on opposite sides of the cut may be pressed outward to permit a chain
link to be inserted in said opening, after which the ends are pressed together thereby
securing the bar to the chain.
