Improved Hook or Catch Link for Chains and the like.
Year: 1898

page_text: Improved Hook or Catch Link for Chains and the like.
I, THOMAS PYBOURNE,, of the Firm of Pybourne's Horse Shoe Company,
Wolsingham, Durham, do hereby declare the nature of my invention to be as
follows:
This invention has reference to an improved construction of hook or catch link
for use as the end or clip link in such purposes as harness and watch chains and
the like.
The improved link would be formed preferably of an elongated shape, with a
part cut away at one of its sides for any adjacent ordinary link to enter. The link
would be split or, slit on its sides longitudinally from the hook head for a U shaped
separate centre piece to work in. This centre piece would be fulcrumed on a pin
at the end of gap, and have a projected extension which will fill up the gap
when the centre piece is oscillated inwards.
When any tension is on the other links of chain, this will act on the U shaped
centre piece and so keep the gap in link locked or filled up until the chain is
slackened.

I, THOMAS PYBOURNE, of the Firm of Pybourne's Horse Shoe Company,
Wolsingham, Durham, do hereby declare the nature of my 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, that is to say:-
This invention has reference to an improved construction of hook or catch link
for use as the end or clip link in such purposes as harness and watch chains and
the like.
And in order that my said invention and the manner of carrying same into
practice may be properly understood, I have hereunto appended a sheet of explana-
tory drawings in which Figures 1 and 2 are side views representing the hook or
catch link in its closed and opened out positions respectively, and Figure 3 is an
edge view looking at the opening out part. Figures 4, 5 and 6 are views corre-
sponding to Figures 1 to 3 of a slightly modified form of the link, and Figure 7 a
view looking at the opposite edge to that shown in Figure 6.
Referring to these drawings:-
The improved link a would be formed preferably of an elongated shape, with a

page_text: part cut away at a¹ at one of its sides for any adjacent ordinary link of the chain
to enter. The link a would be split or slit on its sides or edges at a longitudinally
from the hook head for à U shaped separate centre piece b to work in. This centre
piece would be fulcrumed on a pin at the end of gap, and as shown in
Figures 1 to 3 have a projected extension 62 which will fill up the gap at a¹ when
the centre piece bis oscillated inwards as shown in Figures 1 and 3.
When any tension is on the other links of chain, this will act on the U shaped
centre piece band so keep the gap a in link locked or filled up until the chain is
slackened.
In the arrangement shown in Figures 4 to 7 the centre piece is mounted on a
pin at the opposite side of gap a to that shown in Figures 1 to 3, but works
into a central slit part at a² of link a in a similar manner, the part befilling up
the gap being formed of an enlarged size equivalent to that of the link b.
Having now particularly described and ascertained the nature of my inven
tion and in what manner the same is to be performed I declare that what I
claim is:-
A hook or catch link for chains and the like, in which the central part of link
is slit for a hinged or moveable centre piece to work in, and fill up the gap space in
link, substantially as set forth.
