Abstract

13,611. Hedgeland, F. W. June 12. Motor road vehicles.-Relates to friction - clutch gearing of the kind described in Specification No. 10,496, A.D. 1906, for driving the vehicle in either direction by means of which, when the vehicle is rounding a curve, the overrunning axle is automatically disconnected from the driving-member, while the axles may also drive the motor, and consists in a modified and simplified arrangement of the mechanism. Fig. 2 shows a section of the clutch mechanism connecting the abutting ends of the divided axles 7, 8, and Fig. 4 a section on the line 4-4 of Fig. 2. The driving-member comprises a ring 15 having sprocket teeth 16 and provided with interior inclined friction surfaces 17,18. Cupshaped members 19, 21 also provided with inclined friction surfaces 20, 22 are arranged on each side of the ring 15 and bolted thereto. The squared ends of the axles are provided with multiple-thread screw sections 25, 26 confined against endlong movement by the cup-shaped members, the threads being cut in the same direction, preferably right hand. The threads may be formed directly on the axles. The shifting clutch members 27, 28 mounted on the screws are each formed with double inclined friction surfaces engaging the external members. The outer ends of the internally screwed members 27, 28 are formed to receive rings 29, which are driven from the ring 15 by means of bails 35, which slide laterally in removable plugs 36 mounted in the ring 15. The bails 35 extend round the outside of the rings 29 so as to limit the lateral movement of the shifting members 27, 28.
