Definitions

  • the switching-0d of the current is effected, according to the arrangement which forms the object of this invention, in a manner known by itself, ata separate part of the cylinder which is not directly driven from the switch shaft and which is rotated only for the angle'which is necessary for the switching-off.
  • This transmission is effected according to the invention, by means of an irregular disk mounted upon the switch shaft and of a roller through the intermediary of a rocking lever which is coupled in any convenient manner with the switching off cylinder.
  • Figs. 2, 3 and 4 show in plan view three different switch positions, the switched-off position (Fig. 2), the switching-on position (Fig. and the position at the moment of the releasing by the outwardly situated magnet (Fig. 4).
  • Figs. 5 to 8 illustrate the second form of construction in plan view, the switch being shown in four switch positions, viz in the switched-off position (Fig. 5), during the switching-on movement (Fig. 6), at the Serial No. 496,664.
  • the cam 0 is keyed serves for operating the switch.
  • the cam 0 acts upon a roller (Z which is rotatably mounted in the rocking lever e.
  • the spring 9 is attached with one end to the rocking lever e pivotably mounted upon a support f and with the opposite end to the casing of the cylinder switch, not shown in the drawings.
  • a link It connected with the rocking lever 6 serves to transmit the movements to the pawl lock 2' which consists of a frame fixed to shaft b and having mounted therein a series of pawl latches, as clearly shown by dotted lines in Figures 2, 3 and 4.
  • the last pawl 7c of said lock is connected with the switching oft cylinder 91. (Fig. 1) by a stud Z which is adapted to move in the slit m of the lock.
  • the cylinder a can freely rotate around the main shaft Z).
  • 0 is the blade spring for switching off the part '11 of the cylinder 2) is the releasing pawl, Q the outwardly arranged no-voltage magnet with its armature 1".
  • lfthe releasing pawl of the lock is curved so that its curvature corresponds with that of the cylinder the armature of the outside releasing magnet can operate the releasing pawl by shock within the angle which'is necessary for the switching-off.
  • Figs. 5-8 differs from the form of construction which has just been described with reference to Figs. 14 by greater simplicity in so far as instead of the-centrally. arranged pawl lock e', the part a of the switch which has to be operatedis directly coupled with the rocking levere, so that this part a is coupled with an element situated at the outside of the switch and which does not participate in the rotating movement.
  • FIG. 5 shows the arrangement in thenormal position of rest.
  • a des ignates the handle or a hand wheel which is rigidly connected with the shaft 5 and which is adapted to act directly upon the roller (Z of the rocking lever e by means of the cam 0.
  • a levers is hingedly connected with the rocking lever e and coupled at z with the part a move. ly mounted in shaft 7).
  • the spring 0 serves to return the part a to the switching-off position.
  • a switch shaft a switch member rotatable on said shaft, a spring biasing said member to open circuit position, a cam fixed on said shaft, a rocking lever operated by said cam, means including a latch for connecting said rocking lever to said member, and an electromagnet for actuating said latch to disconnect said rocl: arm and member.
  • a switch shaft In an electromagnetic switch, a switch shaft, a switch cylinder rotatable on'said shaft, a spring biasing said cylinder to open-circuitposition, a cam fixed on said shaft, a rocking lever having a relatively stationary fulcrum, a roller on said lever coacting with said cam, a support fixed to said shaft, a connection between said support and rocking lever, a plurality of concatenated pawls mounted on said support, a pin rigid with said cylinder, the last of said latches being engaged with said pin and the first of said latches having a tailcurved substantially concentric with said shaft, and a relatively stationary magnet having an armature adapted to engage said curved tail.
  • a manually operable switch shaft a switch member biased toopen-circuit position rotatably mounted on said shaft, means including a latch for connecting said shaft and switch member for rotation. together, and a relatively stationary. .magnet for actuating said latch.
  • a manually operable switch shaft a switch cylinder rotatable on said shaft and biased to open-circuit. position, means including a latch fixed to said shaft and a pin rigid with said cylinder connecting said shaft and cylinder, and a relatively stationary ma 'net adapted to actuate said latch to disconnect said cylinder.
