MULTI-PURPOSE SCREEN PRINTING MACHINE ABSTRACT OF THE DISCLOSURE An improved low cost screen printing apparatus for printing on both flat and curvilinear objects. Two vertically aligned shafts support the printing head and, by following the pivotal motion of a rocker arm, raise and lower the printing head relative to the object being printed with a straight vertical displacement, resulting from the controlled movement of the upper shaft by the rocker arm which drives the upper shaft through an elongated slot. The squeegee assembly operates in a timed relationship with the raising and lowering of the screen head to alternatively raise and lower the squeegee assembly concurrently with the raising and lowering of the screen so that the squeegee and flood bar are retained in an operative position and parallel to the screen surface during both print and flood cycles. When the screen and squeegee assembly are in the raised position, the squeegee assembly and screen frame are selectively connectable to a reciprocating carriage, for printing either curvilinear or flat objects.
