Claims4
An apparatus for connecting a lifting tackle to a lifting loop of a submersible pump, said apparatus being adapted to be lowered into a pumping station along essentially vertical guides, comprising:
- a connection yoke;
- means formed at one end of said connection yoke for slidably engaging said guides;
- and
- means disposed at an opposite end of said connection yoke for releasably securing a lifting tackle in a substantially horizontal position and for automatically releasing said tackle upon contact of the tackle with the lifting loop, said securing means comprising a slidable pin member for engaging the lifting tackle, a spring adapted to urge the pin out of engagement with the lifting tackle, and a stop arm for holding the pin against the spring force until said stop arm is engaged by the lifting tackle and is rotated to release the pin so that the spring slides the pin out of engagement with the lifting tackle, whereby a lifting tackle may be lowered into a pumping station for engagement with the lifting loop of a submersible pump.
