of the bill 2 and keeper 5 is positively precluded.
To disengage the hook and keeper, it is only
necessary to rotate the sleeve 12 to aline the notch 5 7
13 therein with the bottom of the slot 1.’ This
leaves the bill 2 free to pass out of the slot throug
the bottom side of the latter.

In conclusion and brie?y stated, the hook em
bodying my invention comprises a body and a 10
belt.v A keeper is pivoted to the body of a hook
at one end of the hook remote from the bill, and
is provided at its free end with a sheath for re- .
ceiving the bill of the hook. Mounted on the
keeper, and rotatable about the axis of the keeper 15
is a sleeve adapted to retain the cell in the sheath.
The sleeve is provided with a notch which is
adapted to align with the open side of the sheath
to permit movement of the bill into and out of
the sheath.
