Abstract
An adjustment mechanism for a button stitching machine includes a shaft rotatably mounted in a support block and having a threaded, forwardly extending portion and a rearwardly extending portion. The threaded forwardly extending portion threadedly engages a bore provided in a rear end of a rear tongue of the button stitching machine. Rotation of the shaft causes the rear tongue to advance and retreat accordingly. A potentiometer-type dial provides an inner scale graduated for indicating fractions of a turn and an outer scale which counts the number of turns.
