Press dampening roll fountain

Claim 1

An elongated fountain pan for receiving an elongated press dampening roll therein, comprising in combination: (a) dampening solution inlet means in said pan in the form of a plurality of spaced apart dampening solution apertures extending lengthwise of the pan and accordingly lengthwise of the dampening roll whereby the dampening solution may enter the pan generally uniformly throughout its length and thus maintain a generally even temperature of the dampening throughout the length of the pan; (b) control means in said pan for use in controlling the level of dampening solution within said pan, said control means comprising an elongated dam-wall extending lengthwise of said pan in spaced generally parallel relation to said plurality of dampening solution apertures whereby said dampening solution entering into said pan via said dampening solution apertures may travel a relatively short distance within said pan before exiting therefrom over said dam-wall, affording ready and thus efficient removal of contaminants from the dampening solution in said pan, and assisting in keeping the dampening solution in said pan at a relatively low operating aperture; and (c) drain means in said pan remote from said inlet means, for use in removing said dampening solution following its passage over said dam-wall.
