Filed: 1937-10-21
Abstract: 498,343. Electric control systems. PETERS & CO., Ltd., G. D., GOODWIN, R. L., and NEGUS, G. H. Oct. 21, 1937, No. 28687. Addition to 474,481. Drawings to Specification. [Class 40 (i)] In the system described in the parent Specification wherein a plurality of mechanisms such as the control mechanisms of the oil engines of rail cars are selectively positioned by motors controlled over independent line circuits corresponding to the selections by any one of a plurality of master control devices, the electromagnetic clutches provided between the motors and the control throttle levers of the engines are arranged to release the levers and allow them to return automatically to their " engine idling " positions when the master controller is moved from a speed position to the idling position. This arrangement ensures a rapid reduction of engine speed to facilitate gear changing. The clutch magnets are housed in casings mounted on the throttle-lever shafts, the outer surfaces of the casings being provided with the contacts for effecting the control of the motors. The system described in the parent Specification is also modified by the provision of two twoposition dead man's switches on the master controller operated by the hand and foot respectively. These switches control electromagnetic brake and engine " stop " valves the arrangement being such that the brake valve is normally energized in parallel circuits when both switches depressed and the " stop " valve circuit is normally open at series connected contacts which are maintained open by the switches. If, therefore, both switches are released, the brakes are applied and the engines stopped. The stop circuit includes selector contacts on the master controller which are opened in the " idling " position so as to prevent stoppage of the engines when the controller is moved to the " idling '' position and both dead man's switches are released. The '' stop valve circuit may also be completed by a passenger's emergency switch.

IPC: B64C27/54
Filed: 1919-11-19
Abstract: 158,732. Pateras Pescara, Raul, Marquis of. Nov. 19, 1919. Screw propellers on a vertical shaft for helicopter aircraft have blades which are varied in pitch during each revolution and the extent of such variation is adjusted by a vertically slidable cam operatively connected with the blades. The boss 1 has radial sockets 19 which carry the spindles 8 of the blades 9. The inner end of the spindle 8 is threaded and engages a nut 6, which is constrained from rotating but can be moved axially by the roller 4, thus effecting rotation of the spindle and blade. Axial movement of the roller takes place periodically during each revolution when the cam is stationary. On moving the cam 3 so that a different contour is opposite the roller 4, a new periodic movement is obtained. Movement of the cam is effected by helical pinions which engage a screw-thread 14 on the cam.
