Abstract: An ink supply cartridge, for use with an insignia applying device having a chassis, a movable insignia element mounted within the chassis and a support member mounted to the chassis and the movable insignia element and pivotally movable into and out of the path of travel of the movable insignia element, includes a housing containing an ink supply portion and having an ink applying member and a retainer member for attaching the ink supply cartridge to the support member. The ink supply portion is adapted to receive an ink reservoir member which is adjustable to control the flow of ink to the ink applying member and the insignia element as desired. The attached ink supply cartridge is positioned to be engageable with the insignia element to ink the insignia element when the element is within the housing in the at rest position.

Abstract: An electro-mechanical marking device for use with various types of apparatus, having a stack sheet feed assembly, includes an open-ended housing adapted to loosely receive and hold interchangeable marking heads in a self-leveling position. The interchangeable marking heads include a resiliently mounted food device which engages the stacked sheets prior to the marking actuated position. The housing includes a solenoid which selectively energizes a drive element to move the element between an at rest position, and an actuated position. The interchangeable marking heads, such as bar-coders, imprinters, marginal word imprinters, daters and numberers, hot die stampers, foil stampers and label affixers, are held in engagement with the drive element to permit the operative movement of the selected interchangeable marking head between the inward at rest position and an outward actuated position.
