ABSTRACT:
A drawbolt for the mating shells of a container has a latch whose spaced e walls are provided with open slots that receive a transverse cross-bar on one end of a loop whose other end is engageable behind a hasp on one of the shells. Outwardly directed lugs on the side walls are received in aligned apertures in spaced guide walls of a frame, such walls having edges defining aligned peripheral cam surfaces which, together with the closed end of the slots in the latch, capture the cross-bar of the loop and establish a pivotal connection between the latch and the loop. By attaching the frame to a plate adapted to be mounted on the other of the shells, the apertures in the guide walls are closed by the plate. The free ends of a pair of upstanding tabs on the plate cooperate with the closed ends of the apertures in capturing the lugs on the latch thus establishing a pivotal connection between the latch and the frame. Pivotal movement of the latch on the frame causes the cross-bar of the loop to follow an arcuate path defined by the cam surfaces of the guide walls of the frame allowing the closed end of the loop to be drawn behind the hasp to releasably fasten together the two shells of the container.
