Definitions

  • This invention relates to electromagnetic vibratory regulators for dynamos driven at variable speed especially on vehicles, the regulators being provided with a contact spring actuated bycontact spring, to affect the operation of the reg-' ulator in an unfavorable manner.
  • the contact spring which bears with preliminary tension against a stop finger which is moved with it, is arranged in such a manner, that, on swinging, it impinges rigidly against the contact for the lower range of speed and resiliently against the contact for the higher range of speed.
  • the Vibrating governor has a magnet frame I with a magnet 2, which carries a current coil 3 and a voltage coil 4. n the upwardly pointing leg of the magnet frame I is suspended, by means of a leaf spring IS, a right angle-shaped armature 5, to the downwardly directed leg of which are secured, so as to be insulated, a contact spring 6 and a substantially rigid stop finger I of equal length.
  • the contact spring 6 bears with preliminary tension against the stop finger I and carries a double contact 8, which on one side passes through a recess provided in the stop finger 1.
  • the contact 8 cooperates with two opposed fixed contacts 8 and I0, 9 being connected to the frame of the magnet and I0 insulated therefrom. As may be seen from the drawing, the stop finger I bears on that side oi'the contact spring Ii which faces the contact 9.
  • circuit diagram II denotes a continuous current dynamo, I2 thev excitation winding thereof, lldenotes a series resistance, It a battery and I5 denotes an automatic charging switch between the dynamo I I and the battery I4.
  • the contact 8 present on the contact spring 5 bears on the contact I0, whereby the resistance l3 in the excitation circuit of the dynamo II is short circuited. If the armature 5 is attracted by the magnet 2 at a certain voltage of the dynamo II, the contact spring 6 is immediately lifted from the contact 8 and thus the resistance I3 is connected in series with the excitation winding I2. If, on increasing voltage, the armature 5 is attracted more strongly, then the contact spring 8 strikes with'its contact 8 against the contact .9, whereby the excitation winding I2 is short circuited. As a result of its preliminary tension,
  • the contact spring 6 damps the impact and in doing this it may be raised from the contact finger I.
  • the stop finger 1 takes the contact spring 6 with it and opens the contact 8, 9. If the armature 5 thereby goes into its inoperative position, then the stop finger 1 causes the contact spring 6 to strike rigidly against the contact I0.
  • the vibrating governor controls the voltage of the dynamo in known manner by periodic opening and closing of the contacts 8, III or 8, 9.
  • the remaining construction or the governor can be chosen in any desired manner.
  • An electromagneticvibratory regulator for dynamos driven at variable speed comprising an armature, a contact spring actuated by said armature, two fixed contacts between which said contact spring is adapted to swing, one of said contacts being for the lower range of speed of the dynamo and the 0ther-of said contacts being for the higher range of the speed of said dynamo, and a substantially rigid stop finger rigidly mounted upon and actuated by said armature together with said contact spring, said contact spring being substantially coextensive with and bearing against said stop finger with preliminary tension whereby, on swinging, the said contact spring impinges rigidly on the contact for the lower range of speed and resiliently on the contact for the higher range of speed.
  • An electromagnetic vibratory regulator for dynamos driven at variable speed comprising a magnet frame, an armature, a spring pivotally securing said armature to said frame. a contact spring and a substantially rigid stop finger, both mounted on said armature, said contact spring bearing against said stop finger with preliminary tension, and two fixed contacts between which said contact spring is adapted to swing, one of said contacts being for the lower range of speed of the dynamo and the other for the higher range 01' speed of said dynamo, said contact spring and said stop finger being substantially coextensive and arranged in such a manner that, on swinging, the said contact spring impinges rigidly on the contact for the lower range of speed and resiliently on th contact for the higher range or speed.
