sense, the regulation is intermittently ap--- plied to prevent hunting.
The drawing illustrates the preferred embodiment of the regulator showing it ap plied to an electrical distribution system.
Referring to the drawings in detail, a generator 1, having a shunt field 2, supplies current to a distribution circuit the leads of which are represented by 3 and 4. A voltage responsive solenoid 5 is bridged across the generator leads and has in series with its winding a variable resistance 6 which permits its manual adjustment. A plunger 20 cooperates with solenoid 5 and has pivotally secured thereto an arm 7 which swings on a fixed pivot 8. The free end of the arm 7 is reduced in thickness to provide flexibility and carries contacting surfaces 9 which engage the improved variable contacting surfaces 10, hereinafter described. A spring 1] and an adjusting screw 12 permit manual adjustment of the mechanical movement of the arm 7.
An automatic rheostat 13 is provided with a motor having twofield windings 1 f and 15 which make it possible to reverse the direction of rotation of its armature 22. A
resistance varying arm 21 is actuated by the,
spectively.
The contacting cams 10 are offset from one another so as to present diflerent portions of their peripheries'to the contacts 9 at any particular moment. They are rotated at a constant speed by means of the gears 17 and the worms 18 which are driven at a uniform rate by a constant speed motor Theoperation of the system is as follows: Solenoid 5 will respond to any departure of the system from its desired predetermined condition thereby causing a deflection of the arm 7 bringing one of its contacts 9 into engagement with one of the cams 10. The degree of deflection of the arm7v will determine the length of time during which such contact 9 is in engagement with its cam 10, the regulator being so constructed that the arm 7 will not remain in constant engage-- ment with a cam 10 during its complete revolution. i
The interruption in the regulation brought about by the breaking of contact between such contact 9 and the associated cam 10.;,
and the reestablishing of this contact as often as necessary to effect the desired regulation, gives solenoid 5 ample time to respond to' the corrected condition in the distribution circuit, and to vary the deflection of its arm 7 in accordance therewith. This method permits any departure in the system to be corrected by constantly decreasing increments of regulation and prevents hunting and its accompanying inaccuracies.
This invention is particularly applicable to systems employing a generator having ahigh time constant in which several seconds have been found to elapse after the operation of the regulator before the rogu lation becomes effective. It may be employed, however, to compensate for the lag in systems employing generators'having low time constants, by revolving the contacting cams at a higher rate of speed. The in vention may, therefore, be adapted for use in various systems by simply modifying the speed at which the cams rotate.
