ABSTRACT:
A mechanism for raising, lowering and tilting a casket bed. The mechanism includes and upstanding threaded rod mounted in a casket for rotation about its longitudinal axis. A bracket is attached to the threaded rod for vertical movement along the rod upon rotation thereof. The bracket has a leg with an opening which receives the rod. This leg is inclined to the rod at the same angle as the lead angle of the threads on the rod. The diameter of the opening in the leg is smaller than the crest diameter of the threads of the rod to form a driving engagement between the threads of the rod and the bracket leg. A casket bed frame is pivotally connected to a the bracket. A friction material is positioned between the bracket and the casket bed frame. The bracket friction material and casket bed frame are joined by a lockbolt under a preset compression which holds these members together in friction engaging contact sufficient to retain the casket bed in a selected pivotal position under its normal load while permitting pivotal movement of the casket bed upon the application of additional force. Stop means are provided to limit the maximum tilting of the casket bed.
