ABSTRACT:
A Supplementary Liquid Dispensing Device is disclosed. The Supplementary Liquid Dispensing Device is particularly useful in lithographic printing presses and in particular for dampening systems within such presses. The device dispenses from an enclosed source of a given liquid a continuous flow of the given liquid which is part of a fountain solution of the dampening system by metering the continuous flow of liquid proportionate to the rate of evaporization of the liquid in a fountain solution with very minimal evaporization loss of the liquid by the device. The device reduces air polution particularly when a volitile liquid such as alcohol is a part of the fountain solution. The device also has the advantage of supplementing and replacing alcohol in a fountain solution in a very inexpensive way without the use of a highly sophisticated and complex electronic system.
