contacts the pin 36 and is also sufficiently wide to intercept the cross shaft 25 the spring 38 is formed of sheet stock and is shaped into a u shaped member where the two major are not quite symmetrical in shape the fixed arm of the spring 38 connects to a flange plate 40 shown in fig6 attached to the front plate 28 and the back plate 33 it is anchored in a generally vertical posture the arm 39 is free to flex and bend it bears to the left against the cross shaft 25 when the cross shaft 25 moves to the left as shown by its dotted line position in fig5 the arm 39 follows it and by that movement pushes the pin 35 to the left returning the rack 35 to its left most position the rack 35 stays in this position when the cross shaft 25 pushes to the right again after completion of the reset step which occurs in the movement of the cross shaft 25 the spring arm 39 serves as a reset mechanism as will be described it is timed in reset to coincide with resetting of the price computer in the gasoline pump the rack 35 has gear teeth on its lower edge and meshes with a gear 44 the gear 44 is mounted on a shaft 45 in fig7 the shaft 45 also supports an arm 46 which is bifurcated at the upper end the arm 46 swings with rotation of the gear 44 the arm 46 extends upwardly to capture a pin 48 in the slot 47 shown in fig7 the.
