Abstract: A typeholding chase which positively clamps rubber type elements, and firmly engages the elements during high speed machine operation. The chase provides secure engagement of type elements, while facilitating interchange of such elements without a need for separate tools. The chase houses a plurality of resilient support members including mounting surfaces as well as spacer blocks and a bias plate for inducing a type clamping force.

Abstract: A disposable ink cartridge for use in automatic marking systems. The ink cartridge is composed of a housing which contains a collapsible elastomeric ink reservoir having an open end secured to a plurality of barrier disks. The barrier disks are apertured to permit passage of ink through and between them, from the reservoir. An ink absorbing member of fibrous or porous material is positioned at the other, outlet end of the cartridge housing. The ink cartridge provides a constant flow of ink when the ink absorbing member is contacted by a print head or the like until the supply of ink is depleted from the reservoir. The cartridge design permits depletion of essentially the entire reservoir under the above conditions.
