Abstract
A stack-forming machine has a telescoping container defined by a vertically reciprocable, downwardly concave press that is received within an upwardly concave lower section that remains stationary during reciprocation of the press. When the press is raised and an upper door on the press and a lower gate on the lower section are opened, the stack may be discharged from the container. The upper door is normally held closed by an overlapping portion of the lower gate, the latter in turn being releasably latched in place, and while the lower gate is swung downwardly by gravity to its opened position as the press is raised, the upper door is powered to its open position through linkage that interconnects the door with the lower section of the container so as to utilize the upward movement of the press as the source of opening power for the door. Included within the linkage is a coil spring that permits the upper door to be held closed by the lower gate when the latter is latched, notwithstanding reciprocation of the press at periodic intervals during the stack-forming cycle.
