Abstract

710,088. Typewriters. JARDINE, Ltd., J., and HARDY, F. S. Feb. 12, 1952 [Nov. 14, 1950], No. 27740/50. Class 100 (4) Letter-spacing mechanisms.-The driving pinion A of an escapement mechanism gears with a worm C which extends the full width of the carriage frame B and is arranged so that it can be rotated to increase or decrease the normal spacing. The worm C may extend through the end plate of the carriage to a knob E which can be manually rotated one amount when required to print a double impression to produce a relief effect or another amount to correctly type a diphthong. The knob is located by a spring- pressed plunger which can be put out of action by a masking plate G when a continuous increase or decrease of letter-spacing is required. The worm in this case is rotated by a frictional drive from a coacting worm J turned by gears K, L from a pinion M meshing with a vertical rack N. The rack N is vertically slidable by a roller N' engaging on a rail O extending across the frame of the machine. This rail is pivoted at one end O' to vary its inclination and is provided with a pointer R at the other end, where it is fixed by a screw T at a desired position on a scale S. The amount of inclination, upwardly or downwardly from the pivot O<SP>1</SP> determines the change in the letter spacing. If the inclination is set at the commencement of a line a justified typewritten script may be produced.
