Abstract
537,409. Gearing &c. LANCIA & CIA. FABBRICA AUTOMOBILI - TORINO - SOC. ANON. Dec. 18, 1939, No. 32462. Convention date, Dec. 21, 1938. [Classes 80 (i) and 80 (ii)] Means for locking a displaceable member, such as a toothed wheel slidable on a shaft, in either of two positions comprises a set of engagement members, such as balls, which are in two groups, one group serving for locking the wheel to the shaft, and the other serving to couple the wheel with a sliding member by which it is displaced. The wheel 2, Fig. 1, is splined on its shaft 1, and its movement is limited by shoulders 5, 5'. The hub 3 of the wheel has apertures containing balls 7, Fig. 5, which in intermediate positions of the wheel rest on the splines of the shaft. In the extreme positions, one or another group of the balls moves into recesses 8, 8' in the splines, so as to lock the wheel. A sliding collar 9 splined on the hub 3 has in its inner surface a groove 11, Fig. 3, which can accommodate the balls. The group of balls which has not moved inwards couples the wheel to the collar 9, which is operated by means such as a fork 14. When one set of balls moves inwards, the other set can move into lateral recesses 12, 12' in the walls of the groove 11. The collar 9 is thereby permitted to pass over the balls that have moved inwards, so as to lock them in position.
