| cylinder 37. Each lever is rocked to the position shown in Figure 2 by a spring 39 so as to hold the annulus 32 away from the plate 30 and disengage the clutch. The clutch is engaged by admitting compressed air through 5 a suitable connection, not shown, into the cylinder 37 so as to move the piston 36 towards the plate 30 and rock the levers 34 which move the annulus 32 towards the plate 30 to clamp the driven plate 31 between the annulus 32 and the driving plate 30. The extent to 10 which the clutch will slip can be varied by varying the pressure within the cylinder 37 and the maximum pressure should be such that the clutch can transmit without slip the full load which can be transmitted through the driving belt 26 (Figure 1). 15 The driven plate 31 is mounted to rotate with a sleeve 40 but can move axially on the sleeve which is splined on a shaft 41. The sleeve 40 is supported by a bearing 42 from the plate 30 of the slipping clutch and by a bearing 42' from a casing 70 so that it can move 20 axially. The sleeve 40 has the driving member 43 of a cone clutch splined on it so that they move axially together. The other member 44 of the clutch is secured to a bevel pinion 45 and is rotatable on the shaft 41. The assembly 44-45 is rotatable in a bearing 46 which 25 restrains it from axial movement in the casing 70. The pinion 45 meshes with a bevel wheel 47 secured on the shaft 27a and a bevel wheel 48 secured on the shaft 27b. The wheels 47 and 48 both mesh with a second bevel pinion 49 which is rotatable on the shaft 41 and is secured to 30 the driven member 50 of a second cone clutch. The assembly 49-50 rotates in a bearing 51 which restrains it from axial 7. | ||
