mechanism. As the arm rotates it will engage with the bill of the pivoted catch 21 and will force the latter from engagement with the hub portion of the arm 11, so that the arm 20 will fall by gravity toward the bottom of the case. At the same time the outer arm 23 will also move downward by gravity and will carry with it the pin 24 and the latter moving into engagement with the switch 25 and closing the lamp-circuit. The lamp will thus be ignited and during the night hours will form a "visual sign to notify the person attendance that a call is coming in. The lamp at the same time will afford a means for illuminating the tape, so that the message may be read. The arms 20 and 23 will remain in a depressed position until the operator, by grasping the handled crank 28 at one end of the shaft, pulls the arm 20 up to position, and the bill-22,
engaging position by gravity, the lower end of the catch being much heavier than the upper end, so that such catch will be automatically moved. to locked position and will remain in this position until another call is received. v
It IS necessary that the operator move the device by hand for the purpose of breaking riding over the" hub portion of the arm 11, will bemoved to is released.
2. In combination with a switch of a lightcircuit, a suitably-mounted shaft, an arm thereon, a catch engaging said arm, means for releasing the catch from the arm, a second shaft suitably mounted, means carried by said shaft contacting with the switch, means for imparting motion to the secondnamed shaft, and a weighted arm carried by the second-named shaft acting in conjunction with the first-named shaft for holding said second-named shaft against rotation until the catch is released.
3 In combination with a switch of a lightcircuit, a suitably-mounted shaft, an arm thereon, a catch engaging said arm, means for releasing the catch from the arm, a second shaft suitably-mounted. means carried ,"by saidshaft contacting with the switch,
means for imparting motion to the second named shaft, an arm carried by the secondnamed shaft, and a bill on said arm engaging the first-named shaft to hold the secondnamed shaft against rotation until the catch is released.
