| movement. The driving member 51 of the second cone clutch is in the form of a rigid annulus secured to a flexible plate 51' which is secured on the shaft 41. The clutch member 51 thus rotates with the shaft 41 but can be 5 moved axially independently of the shaft to engage or disengage the clutch. A tubular extension 53 is secured on the end of the shaft 41 and a sleeve 54, secured to the clutch member 51, has an in-turned flange 55 which fits within the tubular extension 53 so as to locate the 10 clutch member 51 radially of the shaft and support it. A strong spring 56 is compressed between an internal flange 57 on the clutch member 51 and an external flange 58 on the extension 53 of the shaft 41. This spring presses the driving clutch member 51 into engagement 15 with driven clutch member 50 to engage the second clutch and its reaction on the member 53 is transmitted through the shaft 41 to the driving member 43 of the first clutch to press that member into engagement with the driven clutch member 44 and engage the first clutch. The spring 20 will, thus, normally engage both clutches so that both bevel pinions 45 and 49 are clutched to the shaft and would rotate in the same direction and at the same speed. This locks both the shafts 27a and 27b against rotation since neither of them can rotate without rotating the 25 bevel pinions in opposite directions which they cannot do. The two cone clutches constitute reversing clutches for selecting the direction of a turn and either can be disengaged by means of a piston 59 in a cylinder 60 formed in the casing 70. This piston has a piston rod 61 30 to which the inner race of a thrust ball-bearing 62 is secured. The outer race of this bearing lies between 8. | ||
