Abstract

22,553. Moore, S. Bramley-. Oct. 12. Clutches, friction. - Relates to friction clutches of the cone, segment, or other type, in which two clutch springs acting successively are employed. In a cone clutch, as shown in Fig. 2, the operating- collar Z is connected by a sleeve E to the cone A. A sleeve C is connected to the shaft X by pins C<1> passing through slots D in the sleeve E. Springs B, B' bear between the sleeve C and a cover on the outer cone A<1>, and between the sleeve C and cone A, respectively. The end X<1> of the shaft X engages the hollow end of the shaft Y, the hollow space being connected by a valve V with the ordinary system of forced lubrication employed on a motor-car. Any other dash-pot or similar retarding-device may be employed. In order to bring the clutch into engagement, the disengaging-lever is released, and the cone A moves at once into the position shown under the influence of the spring B<1>, the movement of the shaft X and sleeve C being so retarded by the dash-pot that the pressure of the spring B is applied gradually. In a segment clutch, as in Fig. 4, the segments J are pivoted at one end on the driven frame H, and at the other on levers K also pivoted to the frame, and actuated by springs S<1> connected to levers L pivoted to the frame H. The levers L are connected by a dash-pot T and by a spring S, and are adapted to be engaged by pins P on levers M, which engage the levers K and are operated by a sliding cone R on the shaft to disengage the clutch. When the cone R is withdrawn, the levers K, M move into the position shown under the influence of the springs S<1>, and move the segments J into contact with the drum G. The spring S moves the levers L inwards under the control of the dash-pot T, and so completes the clutching action.
