Abstract

New Revolver Design

Lifting of the heads is accomplished by a drive shaft 1 and lift finger 6 utilizing a pivoted lever 2 to lift the write head 3 and an integral lever 4 for the read head 5. Parallel motion is achieved by using flat springs 7 mounted parallel to the drum axis.

Because of the parallel mounting of the head, any change in the dimensions of the mounting means (springs, etc.) does not affect the position of heads along the track. Minor motion of the heads parallel to the drum axis due to temperature changes or other causes is not as critical as motion in the direction of the track. This is especially important in one word revolvers where adjusting of the head positions is extremely critical.
