Abstract

466,136. Typewriters. ROYAL TYPEWRITER CO., Inc. Nov. 22, 1935, No. 32482. Convention date, May 2. [Class 100 (iv)] Keys.-In touch-adjusting means, an anchorplate for the action-returning springs is positively adjusted by means of a member, preferably slidable, which is mounted on the framework and engages the anchor-plate at opposite sides of the centre. In the means shown in Figs. 3 and 5, the action-returning springs 20 are connected to an anchor-plate 22 secured to arms 23 which are pivoted at 24 to the sides 5 of the framework A and are connected to counterbalancing-springs 26. The anchor-plate is movable vertically, to adjust the tension of the action-returning springs, by means of a slide 27 arranged at the front of the machine and having lugs 30 engaging inclined slots 28 in the anchor-plate. The slide is formed with fingers 29<1> resting on the front wall 7 of the framework, and is held in engagement with the front plate 8 by means of a rail 33. A knob 36 on the slide is set with reference to a touchindicating scale 37 on the front plate.
