ABSTRACT:
A machine for imprinting numbers on sheets of paper, particularly in a consecutive order, includes a base in the form of a box-like housing in which is located a levelling mechanism for levelling a platen against which sheets of paper are supported for imprinting a number by means of an imprinting head supported for reciprocal movement toward and away from the platen by means of an arm extending upward from the base member and including a solenoid for reciprocal movement of the print head toward and away from the platen. The level of the platen for precisely adjusting the support surface of the platen for uniformly printing the numbers includes a pair of adjustable screw mechanisms disposed on orthogonal axes for selectively adjusting the slope of the platen. An alternative embodiment includes a solenoid operated plunger acting against a fixed platen disposed in the center of a sheet support table.
