Device for providing the inking system of printing presses with ink

Claim 1

A device for loading an ink fountain of a printing press from sealed cans of ink having parallel end surfaces and a continuous cylindrical wall made of thin axially collapsible material comprising, in combination, a base plate having vertical pillars secured thereto and laterally spaced to provide a flat working area free of lateral confinement and adequate to accommodate cans of ink of normally available size, a pressure plate flatly superimposed above the working area and supported on said pillars, the pressure plate and base plate being dimensioned to extend laterally beyond the can in all directions, the base plate having an aperture generally centered therein, a manually controlled driving means interposed between the pillars and the pressure plate for lowering the pressure plate parallel to the base plate so that when the base plate is seated above the fountain and a can of ink having a puncture aligned with the aperture is engaged between the pressure plate and the base plate, ink is squeezed through the aperture directly into the fountain accompanied by accordion-type collapse of the can to empty flattened condition.

Claim 2

A device for loading an ink fountain of a printing press from sealed cans of ink having parallel end surfaces and a continuous cylindrical wall made of thin axially collapsible material comprising, in combination, a base plate having vertical pillars secured thereto and laterally spaced to provide a flat working area free of lateral confinement and adequate to accommodate cans of ink of normally available size, a pressure plate flatly superimposed above the working area and supported on said pillars, the pressure plate and base plate being dimensioned to extend laterally beyond the can in all directions, the base plate having an aperture generally centered therein, a manually controlled driving means interposed between the pillars and the pressure plate for lowering the pressure plate parallel to the base plate so that when the base plate is seated above the fountain and a can of ink having a puncture aligned with the aperture is engaged between the pressure plate and the base plate, ink is squeezed through the aperture directly into the fountain accompanied by accordion-type collapse of the can to empty flattened condition.

Claim 4

A device for loading an ink fountain of a printing press from sealed cans of ink having parallel end surfaces and a continuous cylindrical wall made of thin axially collapsible material comprising, in combination, a base plate having vertical pillars secured thereto and laterally spaced to provide a flat working area free of lateral confinement and adequate to accommodate cans of ink of normally available size, a pressure plate flatly superimposed above the working area and supported on said pillars, the pressure plate and base plate being dimensioned to extend laterally beyond the can in all directions, the base plate having an aperture generally centered therein, a manually controlled driving means interposed between the pillars and the pressure plate for lowering the pressure plate parallel to the base plate, a puncturing member secured to the base plate within the aperture and having a tip extending upwardly from the base plate, so that when the base plate is seated above the fountain and a can of ink is engaged between the pressure plate and the base plate, the can is punctured and ink is squeezed through the aperture directly into the fountain accompanied by accordion-type collapse of the can into empty flattened condition.

Claim 5

A device for loading an ink fountain of a printing press from sealed cans of ink having parallel end surfaces and a continuous cylindrical wall made of thin axially collapsible material comprising, in combination, a base plate having vertical pillars secured thereto and laterally spaced to provide a flat working area free of lateral confinement and adequate to accommodate cans of ink of normally available size, a pressure plate flatly superimposed above the working area and supported on said pillars, the pressure plate and base plate being dimensioned to extend laterally beyond the can in all directions, the base plate having an aperture generally centered therein, a manually controlled driving means interposed between the pillars and the pressure plate for lowering the pressure plate parallel to the base plate, a puncturing member secured to the base plate within the aperture and having a tip extending upwardly from the base plate, so that when the base plate is seated above the fountain and a can of ink is engaged between the pressure plate and the base plate, the can is punctured and ink is squeezed through the aperture directly into the fountain accompanied by accordion-type collapse of the can into empty flattened condition.

Claim 7

A device for loading an ink fountain of a printing press from sealed cans of ink having parallel end surfaces and a continuous cylindrical wall made of thin axially collapsible material comprising, in combination, a base plate having a pair of vertical threaded pillars secured thereto laterally spaced to define a flat working area free of lateral confinement and adequate to accommodate cans of ink of normally available size, a pressure plate flatly superimposed above the working area and having captive threaded bushings threadedly engaging the pillars, the pressure plate and base plate being dimensioned to extend laterally beyond the can in all directions, the base plate having an aperture generally centered therein, driving means for rotating the bushings in unison for lowering the pressure plate parallel to the base plate so that when the base plate is seated above the fountain and a can of ink having a puncture aligned with the aperture is engaged between the pressure plate and the base plate, ink is squeezed through the aperture directly into the fountain accompanied by accordion-type collapse of the can into empty flattened condition.

Claim 8

A device for loading an ink fountain of a printing press from sealed cans of ink having parallel end surfaces and a continuous cylindrical wall made of thin axially collapsible material comprising, in combination, a base plate having a pair of vertical threaded pillars secured thereto laterally spaced to define a flat working area free of lateral confinement and adequate to accommodate cans of ink of normally available size, a pressure plate flatly superimposed above the working area and having captive threaded bushings threadedly engaging the pillars, the pressure plate and base plate being dimensioned to extend laterally beyond the can in all directions, the base plate having an aperture generally centered therein, driving means for rotating the bushings in unison for lowering the pressure plate parallel to the base plate so that when the base plate is seated above the fountain and a can of ink having a puncture aligned with the aperture is engaged between the pressure plate and the base plate, ink is squeezed through the aperture directly into the fountain accompanied by accordion-type collapse of the can into empty flattened condition.
