  • Patent number: 4407504
    Abstract: An amusement device consists of a box-like structure having a transparent lid which may be opened through the proper positioning of a plurality of tumblers contained on an exterior face of the structure. The transparent lid is of a spring biased construction to facilitate its opening once the proper combination on the tumblers has been set, and a troll-like figurine is releaseable from an interior portion of the structure upon an opening of the lid. If desired, the troll may be provided with an award deliverable to the bearer. Further, the combination required to open the structure is changeable through the use of selectively positionable gears associated with the tumblers.
