Silk screen printing apparatus comprising the usual silk screen frame hingedly secured to suitable support base, and having an inking-squeegee reciprocally movable with respect to the silk screen frame for alternately applying ink to the silk screen and squeegeeing the ink onto the media being printed during the printing operation; a flood bar maintained in a position of close proximity to the surface of the silk screen in one direction of movement of the inking-squeegee for applying ink to the silk screen; a squeegee maintained in a position of close proximity to the surface of the silk screen during movement of the inking-squeegee in an opposite direction for pressing the ink through the silk screen during a printing operation; pin devices carried by the inking-squeegee for automatically pivoting the silk screen frame about the hinged connection in one direction of movement of the inking-squeegee for elevating the silk screen to facilitate removal of the printed media and isertion of the next succeeding media to be printed; an endless chain operably connected to the inking-squeegee to provide said reciprocal movement therefor.
Silk screen printing apparatus comprising support base means, frame means hingedly secured to the support base means and pivotally movable between raised and lowered positions with respect thereto, a silk screen carried by said frame means, inking-squeegeeing means movable to and fro with respect to the frame means for applying ink to the silk screen in one direction of movement and squeegeeing ink through said silk screen in an opposite direction of movement, drive means carried by the support base means and operably connected with the inking-squeegeeing means for providing said to and from movement therefor, and means carried by the inking-squeegeeing means for automatically raising the frame means during the inking of the silk screen and lowering the frame means prior to the squeegeeing of the silk screen and wherein said last-mentioned means comprises pin means rigidly secured to the inking-squeegeeing means and slidably engageable with the frame means for pivoting the frame means about the hinged connection thereof upon one direction of movement of the inking squeegeeing means and pivoting of the frame means about the hinged connection thereof upon an opposite direction of movement of the inking-squeegeeing means.
Silk screen printing apparatus comprising support base means, frame means hingedly secured to the support base means and pivotally movable between raised and lowered positions with respect thereto, a silk screen carried by said frame means, inking-squeegeeing means movable to and fro with respect to the frame means for applying ink to the silk screen in one direction of movement and squeegetting ink through said silk screen in an opposite direction of movement, drive means carried by the support base means and operably connected with the inking-squeegeeing means for providing said to and from movement therefor, means carried by the inking-squeegeeing means for automatically raising the frame means during the inking of the silk screen and lowering the frame means prior to the squeegeeing of the silk screen, said inking-squeegeeing means comprising an independent flood bar member and squeegeeing member, means connecting the squeegeeing member with the drive means to provide alternate raised and lowered positions of the squeegeeing member with respect to the silk screen carried by the frame means, and means operably connecting the flood bar member with the frame means and silk screen to provide substantially constant contact of the flood bar member with the silk screen, and wherein the connecting means between the squeegee member and the drive means comprises a pair of spaced mutually parallel simultaneously vertically reciprocal rod members carried by the drive means and the connecting means between the flood bar member and the frame means comprises a pair of spaced mutually parallel pin members connected with the flood bar member and slidably engagable with said frame means and movable to and fro in synchronization by said drive means.
