Keyboard Kickback Elimination

Spring member 165 is attached to the restoring bail 60' of an interlocked open keyboard for eliminating an annoying kickback sometimes encountered. The keyboard is shown in U. S. Patent 3, 152, 759.

Member 165 strikes lower cantilever spring 42 when the latter is engaged in notch 84 forcing spring 42 out of 84. Narrow tang 142 is added to spring 42 for this purpose. Member 165 is in a tine of a comblike spring closely similar to the upper cantilever spring 41.

The lower edge of the crossbar 23 is relieved with a 5 degrees bevel 123. This permits heavier loading of the selection bars 46, due to a larger than usual number of contacts in the coding section, with the same pressure on keys 14.
