Abstract: In the combination of a spring driven motor having a winding shaft which rotates less than one complete revolution during the unwinding of the motor from a fully wound condition, escapement means for permitting the motor to unwind at a controlled rate and a bell to be struck immediately proximate to completion of unwinding of the motor, there is provided an improved bell actuating mechanism. The bell actuating mechanism comprises a bell post coaxially mounted at one of its ends on the winding shaft for rotation with the winding shaft, means coaxially mounting a gong bell onto the other end of the bell post for rotation with the bell post and the winding shaft, a hammer for striking the bell, a spring mounting the hammer immediately adjacent to an inner surface of the bell, an arm integral with and extending outwardly from the bell post for rotation with the bell post and the winding shaft, the path of movement of the arm intersecting the hammer and the hammer being rotationally so positioned relative to the axis of the winding shaft and the bell post that the arm engages the hammer as the unwinding of the motor is completed. The spring flexes, the arm then disengaes from the hammer, whereupon the unflexing of the spring throws the hammer against the gong.
