Definitions

  • This invention relates to switches or switcliboards for controlling a plurality of electric circuits such,.for example, as the switchboards for controlling the starting, lighting, and ignition circuits on motor vehicles.
  • the object of the present invention is to simplify and cheapen the construction of such devices and to provide for their reduction to a comparatively small compass in order that they may be easily and rapidly installed in position and will present aneat external appearance when so mounted.
  • the invention consists in a switchboard for controlling a plurality of electric circuits having a single switch adapted to control more than one of said circuits, independently.
  • the invention also consists in a switchboard of the above characterhaving means for locking the switch against operation when it is desired that the circuits shall not be under control.
  • the invention further consists in a switch board of the above character in which the key for operating the lock will also control an electric circuit additional to those controlled by the switch. 7
  • Figure 1 is a front elevation of the switch board. 1
  • Figure 2 is a front elevation partly. in section. r
  • Figure 3 is a side sectional elevation.
  • Figures 4 and 5 are views illustrating two; switches shown in Figure 3.
  • the insulating plate I arrange the necessary contacts for the battery and varioiis lamps comprised in the lighting set as denoted respectively in Figure 6 by the reference letters (Z c fg and also an earth connection it, and in conjunction with such contacts I arrange a contact'bridge i ( Figure 5) which is adapted to be rotated so that any or all of such contactsm-aybe made or broken according as any, all, or none of'the lamps require to be lighted.
  • the rotation of the contact bridge i is effected by a switch or handle 70 which is so constructed and arranged that in addition to the. motion of rotation for controlling the lighting circuit it is also capable of an axial or rectilinear movement for operating the starting switch or other means employed for starting the motor either directly .or
  • the barrel or cylinder ofthe rotary lock m itself carries or is adapted to actuate a contact bridge 0 ( Figure 4) which'may.
  • switchland locking means are preferablysuch that .the switch may be locked in any of its angular positions controlling the lighting circuit while at the same time the ignition and starter circuits may be locked in the off position.
  • controlli'n switch 70 embodies a central mem' her 1' to w iich the switch knobis secured b means of a screw .9 or otherwise and whic,
  • the starting switch may be moved axially for the purpose of operating the starting switch (or the start ing brush in the case where one of the motor brushes is employed as the starting switch) while such central member is surrounded by a tube or sleeve t which carries the contact bridge a and which may be caused to engage with the knob or handle by means of grooves or recesses engaging projections or pins upon the handle or by any other suite able means which while permitting of the withdrawal of the handle for operating the starting switch will yet transmit rotationof the handle to the sleeve t for the purpose of rotating the contact bridgei in a manner. to control the lighting circuit.
  • the tube or sleeve 6 is provided with a series of apertures or recesses u adapted to cooperate with a V-shaped or like recess 0 in the member 1', the apertures to being arranged peripherally in positions corresponding to the various angular positions which the lighting switch may be required to occupy, and in each of such recesses is a ball w which also in part projects into the recess 1). Be tween the member If and the lock m is a pin or bolt a?
  • the switch may be freely operated and owing to the fact that there is a plurality of recesses corresponding to the various angular positions of the lighting switch the latter may be turned to any one of such positions and then looked therein by the locking means while at the same time the starting and ignition circuits will also be locked against operation, it being understood that the contact bridge 0 actuated by the locli is so arranged in relation to the cont-acts that the ignition circuit is otf when the locking device is in its locked position.
  • A. suitable stop 1 may be provided in con junction with the lock for limiting the rotational movement of the same in order to ensure the correct positioning of the ignition contacts, and if necessary or desirable a similar stop or stops may be provided in conjunction with the starting and lighting switch, these arrangements ensuring that the devices themselves will be arrested with the result that no pressure may be exerted upon the contacts such as might the case were these themselves to carry the stopping or arresting devices.
  • a switchboard for controlling the starting, lighting and ignition circuits on motor vehicles comprising a switch mem ber adapted for both rotary and axial movements for controlling two of said circuits, and a locking member for locking said switch against both movements, and adapted to control the third circuit.
