Abstract

1,053,187. Typewriters &c. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 7, 1964 [Sept. 25, 1963], No. 36631/64. Heading B6F. [Also in Division F2] A spring motor for applying to a carriage driving shaft 12 of a typewriter disclosed in Specification 1,053,186 an output driving tongue having a fixed limiting value comprises an input shaft 17, 22 which is connected through a one-way clutch spring 23 to a sleeve 16 rotatable about the input shaft and in turn connected to one end of a spiral spring 20. The sleeve 16 is also connected through a further one-way clutch spring 29 to a fixed collar 28. Rotatable about the sleeve 16 and attached to the other end of the spiral spring 20 is a spring housing 15 which drives the output shaft through gearing. The housing 15 is provided with two clutch release arms 26, 31 which co-operate with projections 24, 30 of the clutch springs 23, 29 respectively to disconnect the input drive when the input shaft 17, 22 has rotated by a predetermined amount in one direction or to disconnect the sleeve 22 and the fixed collar 28 when the housing has been rotated in the opposite direction by a predetermined amount. The spring 20 can. therefore, only be wound to a fixed value tension.
