Abstract

1,071,380. Typewriters &c. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 8, 1965 [Dec. 11, 1964], No. 47179/65. Heading B6F. [Also in Division F2] In a typewriter in which a spherical typehead is moved in letter-space direction by an escapement mechanism described in an earlier Specification, a rebound limiting device is attached to the type-head traversing lead screw 14 and is operative when a stop 18 on the escapement wheel is engaged by its escapement pawl. The rebound limiting device 21 comprises an annular inner hub 60, Fig. 3 (not shown), rigidly attached to the lead screw 13. Upon this hub is fixed one end of a spring clutch 64 wound in such a direction over an outer hub 62 such that when the lead screw 13 is turned in direction of arrow 14 viz. in the escapement or driven direction, the spring is unwound. Rebound movement is absorbed by the spring 64 tightening and driving the hub 62, connected to a weight 63. Surrounding the weight 63 are a pair of friction brake shoes 68 having an adjustment 70 to provide additional load in the rebound direction of movement.
