My invention consists in fitting to the upper part or shank of the hook, a balanced
tongue piece so pivoted that the nose of the tongue piece automatically closes against
the point of the hook, after the shackle has been inserted, by the action of a tail piece
which, being pressed back by hand, the nose of the tongue piece clears the point of
the hook and the shackle can be detached, when the tongue piece automatically
closes the hook till the shackle is again inserted. When the hook is to be opened
to detach the shackle, the operator's hand in pressing back the tail piece cannot be
injured being at the back and clear of the shackle whilst the tail piece does not.
obstruct the eye of the hook.

get out of order by the rough handling to which they are exposed.
My invention consists in fitting to the upper part or shank, A of the hook a
balanced "tongue-piece "B so pivoted that the nose of the "tongue-piece" auto-
matically closes against the inside point of the hook, after the shackle has been
inserted, by the action of a "tail-piece" D which, being pressed back by hand, the
nose of the tongue B piece clears the point of the hook C and the shackle can be
detached, when the "tongue-piece" B automatically closes the hook till the shackle is
again inserted. When the hook is to be opened to detach the shackle, the operator's
hand in pressing back the "tail-piece" D cannot be injured being at the back, and
clear of, the shackle whilst the "tail-piece" D does not obstruct the eye of
the hook.
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 as novel is
The application of a “tongue-piece" attached to the shank of hook as herein
described.
