Abstract
Abstract There is disclosed a pressured liquid applicator which feeds the liquid to the applying surface in an even flow and at the control of the operator. In each embodiment there is a plurality of delivery tubes, and each tube has a positive open-close operation so that substantially the same force is applied to the liquid passing through each delivery tube, thus achieving the even distribution of the liquid. The actuation of the open-close operation is at the operator''s hand, requiring a minimal disruption in the application of the liquid while the applicator surface is being resupplied. In several embodiments of the applicator, the pressure of the liquid being supplied is used to automatically return and maintain the applicator in the closed position unless the operator applies a positive action to open the applicator for resupply of the liquid.

Claim 1
Independent Claim
275 words
A fountain liquid applicator comprising a brush member having a handle, head and attached bristles, an outer cylindrical member transversely located in said head portion of said brush and having spaced-apart apertures therein, a plurality of spaced-apart depending flexible tubes attached to said outer cylindrical member and aligned with said spacedapart apertures, said depending tubes imbedded in said bristles, an inner cylindrical member closed on one end by a rim portion and having a plurality of spaced-apart apertures, said inner cylindrical member slidably positionable within said outer cylindrical member for cooperatively aligning said spaced-apart apertures of said inner cylindrical member with the spacedapart apertures of said outer cylindrical member, said rim portion on said closed end limiting travel of inner cylindrical member in one direction, a source of pressurized liquid, connecting means for supplying said pressurized liquid to the interior of said inner cylindrical member, an arm member pivotably mounted on said handle portion of said brush, a lever member interconnecting the rimmed end of said inner cylindrical member and one end of said arm member for permitting transverse movement of said inner cylindrical member in response to pivoting movement of said arm member, a spring member connected to said arm member and biasing said arm member to pivot in a direction that would cause the apertures of the inner cylindrical member to register with the apertures of said outer cylindrical member, and a pin-like stop member located on said head portion of said brush for engaging one end of said arm member and limiting arcuate movement of said arm member and thereby limiting the travel of said inner cylindrical member in the other direction.
