  • Patent number: 4155304
    Abstract: A device for loading an ink fountain of a printing press directly from sealed cans of ink. The device includes a base plate having a pair of vertical threaded pillars laterally spaced to define a working area adequate to accommodate cans of ink in all normally available sizes. A pressure plate flatly superimposed above the working area has captive bushings which threadedly engage the pillars, the bushings being rotated in unison for lowering the pressure plate to the base plate. An aperture is generally centered in the base plate. Thus when the base plate is seated above the fountain and a can of ink having a puncture alined 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.
