Abstract
717,314. Typewriters. OLYMPIA WERKE WEST GES., [formerly ORBIS BUROMASCHINENWERKE GES. March 30, 1951 [April 8, 1950; March 6, 1951], No. 7382/51. Addition to 713,164. Class 100 (4) Keys. - In a resiliently mounted keybutton 1 for typewriters, calculating and like machines wherein a keylever 5 and a stem 3 of the key-button have a limited relative movement controlled by a cylindrical pressure spring 8 the key-lever 5 is provided with a notch 6 with which is engaged the lower end of a slot 4 in the stem 3. The spring 8 is supported in a cup 9 s'otted to pass the stem 3 and to non-rotatively engage a projection 7 on the key-lever 5. The key-button 1 is formed with a rim 2 to slidingly surround the cup 9. A modification is shown in Fig. 3 wherein the key-lever is upward directed at its end and is slidingly engaged by the stem 3 which is bent at 11 to prevent angu'ar displacement. Alternatively the stem may be provided with projections extending at right angles along the lever 5.
