Definitions

  • the subject of the present invention is an improved-high tension switch intend-ed for operation by low tension current and especially adapted l'or switching comparatively high tensions (such as 220 volts) which are,
  • the low ⁇ tension current used for the op eration of the switch is supplied by cells
  • accumulators or fromthe low tension side generated by a separate source of low tension current no-t dangerous to the human body, said member being operated by a connecting rod that is brought into and retained in a suitable position ready for the succeeding switching operation (on when the switch is oll' and off when the switch is on, or tor switching over in the case of series or other special switches) by means of two independent or separate pressure springs arranged to come into action alternately and neit-her of which influences the action of the other.
  • the one pressure spring is in operation and acts on the rod the other spring does not make contact with said rod.
  • the rod is tilted by the spring pressure into the necessary ready position t'or the next switching operation in such manner that of the two alternately acting springs the only spring pressing on the rod at any time is the one that is to perform the task of tilting the rod into the succeeding ready position after a switching operation has been performed.
  • the switchv member has studs for the connecting rod whereas co-acting surfaces are provided at the lower end oit said lod such that when the rod comes to bear against .either of said studs, the eort f of traction exerted by the electromagnet is transmitted to the switch member.
  • the studs may also serve as supports for the alternately acting springs.
  • a stud or stop may be provided on the connecting rod for co-operation with notches cut in the lower side of the switch member.
  • Figures 1 to 4 represent vertical sections through the commutator showing the movable parts in four different positions
  • Figure 5 represents a vertical section through the commutator at right angles to that of Figures l to 4
  • Figure G represents avertical' section of another embodiment in which the low-current coil is omitted.
  • a denotes 'the solenoid
  • b an iron clamp for the same
  • c the iron core, secured to the clamp b by the nut e
  • d is a copper spindle secured in said core
  • f is an iron armature provided with a through longitudinal bore loosely surrounding the copper spindle cl, so that the armature is able to. move longitudinally
  • g Figure 4 is a spiral spring arranged round the armature and exerting on the latter a force tending to thrust the latter outward
  • 7L is the connecting rod, one end of which is articulated to the armature'by means of a pin i.
  • j is asmall plate set edgewise on the rod L and serving to limit the angular stroke of the same by contact with a spring fn. or a spring 0,' 7c is the switch lever ⁇ for the high tension current.
  • the switch lever lc pivots on a shaft r and has fitted thereto .on one side of said shaft, or on both sides if the switch is of the double pole variety, a short piece of insulating tube p. On the end of this tube is fixed a copper contact ringg, flattened on opposite sides in such manner that these flattened surfaces are not parallel but diverge upwardly. rlhe object of this is to retain the commutator lever between the two contact springs s and t after the rod 71, has returned to its position of rest.
  • Said contact springs s and t are connected to the high tension circuit, and the two terminals u and o ( Figure 4) are connected to the ends ot the winding of the magnet coilV a and also to the low-tension current circuit.
  • Spring jaws w holdthe switch lever 7a when the latter is not engaged between the contact springs s and 2f.
  • a spindle (Figure), which is mounted on the iron clamp bfand carries a button, limits the downstroke of the armature f.
  • Two stops y and a prevent the switch 'lever 76 from turning too far in either direction.
  • the whole unit is lli) mounted on a base plate a, a ofinsulating material.
  • Figure 1 shows the positions of the moving parts of the switch when the magnet' tension circuit through the contacts s, z5 and the contact ring g. .Y
  • the harpoon rod is replaced by a rod terminating in a spindle at the lower end and acting in the same manner for reversing the switch lever, two notches being cut in the lower side of said-lever to form stops, one on each side of its pivotal point, and situated at the same distance apart as the two studs Z and m in the arrangement according to Fignres l to 4.
  • the spindle of the connecting i'od is caused to engage the notches or stops by the spring mechanism of the commutator lever.
  • a switch member arranged to be actuated by a current impulse generated by a separate source of low-tension currentnot dangerous to the human body
  • a tiltable and slidable connecting rod for operating the switch member
  • studs on the switch member co-acting surfaces at the lower end of the rod such that when the rod comes to bear against either of said studs the eiiort of traction exerted by the low-tension current inipulse on the rod ,is transmitted to the switch member
  • two separate pressure springs arranged to act alternately and independ- -ently upon the connecting rod to bring and maintain the saine in position ready for the next succeeding switching operation.
  • a switch 'member arranged to be actuated 'by a current impulse generated by a separate source of low-tension current not dangerous to the human body
  • a tilt-able and slidable connecting rod for operating the .switch member
  • studs on the switch member coacting surfaces at the lower end of the rod such that when the rod comes to bear against either of said studs the effort of traction exerted by the low-tension current impulse on the rod is transmitted to the switch meniber
  • two separate pressure springs mounted on the aforesaid studs and arranged to act alternately and independently upon the connecting rod to bring and maintain the-same in position ready fr the next succ eeding switching operation.
