Definitions

  • My invention relates to a new or improved regulating switch and is particularly adapted for use in connection with cinematograph projectors, especially in cases where duplicate machines are used, or where a single machine is used and the switchgear is also arranged to control the lighting circuit of the theater or similar locality.
  • the object of the invention consists in a new or improved arrangement whereby the amount of current switched on in either one or two arcs or in one are and the lighting circuit, is limited to a predetermined maximum.
  • the switch arms for each set of resistances are arranged to move over the usual radially arranged contact studs, preferably disposed side by side or one above the other.
  • These switch arms are connected by two hinged or pivoted connecting members, the inner ends of each of which are pivoted to one another, while their opposite ends are connected to the respective switch arms.
  • the inner ends of each of the connecting members are provided with projecting portions or stops each arranged to engage the opposite member and thus limit the stroke or extent of rotation of either switch arm relatively to the other.
  • Fig. 3 is a part end elevation of Fi 2 seen from the left.
  • the switch board 1 is provided with two sets of radially disposed contact studs 2, 2, connected in the usual manner to two sets of resistances (not shown in the drawings).
  • Each set of contact studs is provided with a switch arm 3, 3 pivotally mounted on the sw tch board at 4, 4, respectively.
  • the switch arm 3 has pivoted thereto at 5 one end of a connecting member 6 while the switch arm 3 has pivotally connected at 5 one end of a connecting member 6.
  • the members 6 and 6" are connected at or near their inner ends by a pivot 7 or the like.
  • the member 6 is provided at its extreme inner end with a rcarwardly projecting stop or the like 8 located in such a manner as to engage one edge or side of the member 6, while the member 6 is provided at its inner end with a forwardly projecting stop or the like 8 arranged to engage one edge of the 0pposite member 6.
  • Each of the switch arms is provided with an operating handle 9, 9, secured at or near the front end of the rotatably mounted holders 10, 10*, respectively.
  • a pair of stop pins 11 and 11 are arranged between the two series of contacts to prevent the switch arms being moved off the contacts.
  • the switch arms 3, 3 are in the position shown in Fig. 1, both are in the zero position in which no current is passing through either of the resistances. If now it is desired to switch on the are or other electrical circuit connected with the contact studs .2, the switch arm 3 is rotated in an anti-clockwise direction, that is to the position shown in full lines in Fig. 2, in which position the maximum amount of current is switched on in one circuit while no current is passing in the other.
  • the switch arm 3 will have to be rotated in a clockwise direction will be readily understood,
  • the stops 8, 8, on the inner ends of the members 6, 6, are so arranged that the maximum movement of the switch arms is reached, when for instance, one arm is moved to the position in which the full current is allowed to pass and the opposite arm is in zero position. If the switch arm 3 is now rotated in a clockwise direction, the opposite arm 3 will be moved back toward its zero position, to a corresponding extent to which the switch arm 3 is advanced.
