2 Claims. (01. 101364) The principal objects of this invention are to a mercury contact I! which of course tilts with provide means for keeping the level of the ink the lever and the float. When the float lever is in an ink fountain constant so that it will deliver in the position shown in full lines in Fig. 3, the ink uniformly; to provide such means in a form contacts I! are broken. These contacts supply 5 in which only a very small amount of work is electric energy to solenoids IQ of two solenoid 5 required in operating the valve for regulating the controlled valves l8. Consequently at this time level of the ink and there is little danger of the when the level of the ink in the float chamber is caking of the ink, and to provide a valve operated high these valves are closed. by the energy from an independent source not in When the level of the ink in the float chamber any way dependent on the direct buoyant power is lowered the float 20 descends as indicated in 10 f fl t r i d in th i 1 dotted lines in Fig. 3 and this establishes the Other objects and advantages of the invention contacts I! by the swinging of the same.
