ABSTRACT:
A coffin bed adjusting apparatus for providing both elevation and tilt adjustments to a coffin bed in a burial casket. The bed frame is connected to a bed support member which is pivotally mounted to an elevating support member. The elevating support member is threadedly mounted on a threaded shaft, the rotation of which adjusts the vertical height of the bed. A rack is slidably mounted on a threaded shaft, the rotation of which adjusts the vertical height of the bed. A rack is slidably mounted to the elevating support member, and is engaged to a pinion which is also mounted to the elevating support member. The rotation of the pinion drives the rack, which translates the rotating movement into a pivoting of the bed support member thereby causing a desired tilt of the casket bed frame. This pivoting is achieved by the interaction of a slot in the bed support member and an arm on the rack. The pinion which moves the rack is rotated by a second shaft. The second shaft engages the pinion only to rotate it but the pinion freely slides vertically on the second shaft.
