Abstract
As a carriage carrying a mooring line guide is lowered by paying out a hoisting line two retaining projections mounted on the carriage are inserted into complementary stationary sockets to anchor the carriage in a lower position, As the carriage reaches such lower position two reciprocable latch pins mounted on the carriage are projected by compression springs into stationary sockets to lock the retaining projections in their sockets, Retraction of such latch pins in opposition to the force of such compression springs to remove the latch pins from their sockets is effected by tensioning of the hoisting line, The carriage is guided for elevational movement by rollers engageable with upright tracks or by guide sleeves encircling an upright taut guide line.
