Abstract
Abstract A line clamp comprising a ring plate adapted to be secured in position on a mounting surface, e.g., a deck, or other platform, or the like, by means of headed screws, and with a sleeve mounted in the center thereof and projecting downwardly therefrom with a bore extending into and through the supporting surface. A shank mounted for axial movement in this sleeve has a dished upwardly convex clamp plate on its upper end, and a spring draws the shank downward to releasably clamp a line between the dished head and the mounting ring.
