ABSTRACT:
A marking device wherein liquid is dispensed through the interfacial spaces in a bank of thin blades to an article pressed into engagement with the lower ends of the blades and wherein the flow of liquid to the blades is controlled by maintaining a vacuum in the storage tank which supplies the liquid to the blades characterized in the combination therewith of improved vacuum-producing means by means of which the vacuum of constant predetermined pressure can be maintained with a lesser volume transfer and, hence, with less evaporation of the liquid material, with less work output and, hence, less noise output, and with improved longevity of the apparatus.
