Abstract

A manually operated silk screen printing apparatus having a printing bed and a chase overlying the printing bed for removably mounting a screen in alignment with the overlying printing bed. Preferably, a single ball-shaped handle or joystick is mounted on the top of the squeegee carriage for pushing or pulling to slide a squeegee carriage mounted on a lever arm over the center of the screen. The carriage travels on a three-point bearing arrangement with a guide or track surface on the lever arm. Flipping of the handle through an overcenter position reverses the squeegee and the carriage for the respective flood and print strokes. More specifically, the lever arm includes a generally horizontal guide track overlying the chase and extending approximately the length of the screen. The guide track is centered with respect to the chase and guides the carriage. The squeegee blade is centered in perpendicular relationship along its length to the guide track and is movable through a predetermined angle with respect to an axis perpendicular to the surface of the stencil screen for both the print and return stroke.
