Abstract
104,723. Napier & Son, D., and Rowledge, A. J. March 13, 1916. Systems for controlling travel for a fixed distance or number of revolutions.-Relates to electric control systems for operating the mechanical clutches and brakes used in epicyclic variable-speed gearing, particularly of the type described in Specifications 16,595/15 and 16,596/15, [both in Class 80 (ii), Gearing, Variablespeed &c.]. Gear for operating two clutches and three brakes, as described in the latter Specification, is described. Clutch and brake-operating-cams H, H<1>, H<2> are secured on a shaft G driven directly or through gearing by a motor L. The shaft G may be rotated clockwise from the neutral position shown, in a series of steps to adjust the cams for forward speeds, and in the opposite direction for reverse. The cams are so formed as to be locked in their set positions, and also as to bring all the clutches, etc., to neutral or disengaging positions if the cams are advanced half the normal speedchanging distance. Secured to the shaft G are a pair of conducting segments Q, Q<1> separated by gaps or insulations R, R’. A ring S carries a series of brushes Tx, Tr .. T’, Ty, of which the brushes Tx, Ty, are connected to the reversing-coils X, Y of a reversing switch N, and the brushes Tr .. T<4> are connected to push button or lever switches &c. Or .. O<4> in the circuit of a battery M. The push-buttons may be so connected that contact is not broken until a new button is pressed. The ring S is connected by a link S’ to a pedal and may be rotated clockwise through a distance equal to half that between two brushes Tn, T<1> &c. Assuming the gear to be in neutral position with the parts as shown, if the switch O<1> is closed current passes through the coil Y and moves the reversing-switch over to connect the contacts N<1>, V<3> with the contacts Y’, Y<2> respectively. This sends a current through the armature L’, and field L<2> of the motor L und also through a coil L<3> which disengages a brake normally engaging the armature of the motor. The shaft G and segments Q, Q<1>, are thereby rotated until the gap R reaches the brush T<1>, whereupon the motor stops and the brake is applied, the first speed being thus engaged Further rotation is produced by closing the switches O<2>, O<3>, O<4>, or backward rotation by closing the switch Or or any switch for a reduction of speed, whereupon the coil X is excited and moves the reversing-switch to connect the contacts X<1>, X<2> with the central contacts. If, while the switch is still closed, the ring S is rotated a half-step by the pedal, the segments Q, Q<1> follow for a half-step and the cams H, H<1>, H<2> disengage the clutches and brakes. When the pedal is released the ring S returns and the segments follow. If the current fails, the armature brake may be disengaged by hand and the shaft G may be rotated by a crank handle, or by rack and pinion gearing which is normally kept out of mesh.
