Clockwork Bell Patents (Class 116/91)
  • Patent number: 4232474
    Abstract: A toy safe having a box-like housing forming a compartment and a closure member hingedly coupled thereto for closing the compartment. An alarm mechanism is provided adjacent a sidewall of the housing with an aperture extending through the sidewall in proximity thereto. The alarm mechanism includes an alarm member such as a bell with a clapper mechanism pivotally mounted within the compartment adjacent the bell, the clapper mechanism having a tab portion in proximity to the aperture for engagement by a key member inserted through the aperture. The spring-wound actuating member coacts with the clapper member to intermittently pivot the same during unwinding of the spring, the actuating member including a handle positioned and configured relative to the interior of the closure member with a stop member engaging the handle member to prevent unwinding of the spring after the key is removed and to permit actuation of the alarm mechanism when the closure member is opened without the key.
