The signals are of the 60-degree, 2-position type, using Xew YorkCentral standard spectacles and blades, which impose on the signalmotor a load equal to the lifting of a 17-lb. weight, at a distance of4 ft. from the center of the shaft. With this load the motor willclear the signal in from two to three seconds. The circuits by which signals arc controlled are shown in anaccompanying figure, which calls for a full block overlap, and thecontrol of the distant signal through a circuit breaker on the home Cos. type, with dynamic indication-current return. These signals,where slotted, will return to the stop position when the currentthrough the slot magnet is open, but the return indication from thesignal motor is not received at the lever until the lever is firstrestored to the normal position. The operating circuits for the sig-nals are r
