Abstract
A non-rotating wedge-shaped ink agitator which reciprocates within an ink fountain along the length of an ink fountain roller. The ink agitator has a substantially flat bottom surface, side surfaces extending upwardly and outwardly from the bottom surface and a top surface which slopes toward the end of the agitator adjacent the ink fountain roller.
Claims12
A non-rotating one-piece ink agitator for use in an ink fountain having an ink fountain blade with a substantially flat upper surface and an ink fountain roller, said ink agitator being adapted to be reciprocated back and forth in the ink fountain along the length of the ink fountain roller comprising:
- (a) a substantially flat bottom base surface in close proximity to the upper surface of the ink fountain blade;
- said base surface being relatively wide at one end and narrowing to a relatively narrow portion adjacent the ink roller;
- (b) a pair of side surfaces extending upwardly and outwardly from said bottom surface thereby forming a plow angle between the bottom surface and said side surfaces;
- (c) a top surface extending between the edges of said side surfaces;
- (d) said bottom surface, said side surfaces and said top surface forming an isosceles trapezoid when viewed in vertical section and having an area which is smallest adjacent the ink roller and gradually increases as the vertical section is taken in planes spaced from the ink roller, and
- (e) said side surfaces being tapered towards the ink roller thereby forming a cone angle.
