Abstract

381,296. Typewriters. LIPP, C., 1, Karlsruherstrasse, Halensee, Berlin. Aug. 29, 1931, No. 24379. [Class 100 (iv).] Machines for perforating paper; paper-backings.-A paper support or backing for use in producing indelible typing on typewriters or like machines has a grained or grooved surface, harder than the platen but softer than type, and is adapted to be associated with the platen in a readily removable manner. The support may consist of a thermoplastic material such as celluloid or hard rubber, and the grooving may be produced by machining or by stamping, in which case the tips of the graining may be made harder than the body of the support. In Fig. 4, the support is a curved sheet 5, fitting snugly to the platen 2 over which it may be wound in the usual way under the paper sheet 6. The support may be a complete thin cylinder which is slidden endwise over the platen. In Fig. 7, the support comprises two grained strips 1, 1a which are connected by metal strips 7, 7a spring-hinged together at 8 so as to embrace the platen 2. A single grained strip may be connected to arcuate metal springs which partly surround and grip the platen.
