Definitions

  • This invention relates to charging-switches for storage batteries, the object being to provide a simple and efficient device for the use of persons not familiar with electrical apparatus and others and by means of which the charging-current cannot be allowed to pass through the battery in the wrong direction.
  • My improved apparatus includes an elec tromagnet and a permanent magnet acting upon each other, in combination with a circuit-closing lever and a latch for said lever controlled by the cooperation of the magnets.
  • Figure 1 is a central vertical section of the improved switch with parts in elevation.
  • Fig. 2 is a horizontal section through the casing, showing the mechanism in plan; and
  • Fig. 3 is a diagram of the circuits.
  • A is a base of insulating material, such as slate or wood
  • B is a box or cover adapted to rest upon the base and cover all except a portion A along one side thereof.
  • a number of terminals a and a are fixed on the said uncovered portion.
  • a permanent magnet C is mounted upon the base.
  • an electrical helix D is mounted upon the magnet.
  • E is an electromagnet whose soft-iron core eprojects from both ends of the helix, one end being pivotally connected with the upper end of a standard f, while the other end projects over the pole of the permanent magnet C and is normally retracted therefrom by a spring f..
  • the pole-piece of this magnet carries a latch or hook f reaching forward and adapted to engage with the upper end of a lever g.
  • This lever is pivoted near the base and has a handle g projecting through acurved slot in the casingB for hand manipulation.
  • the lever also carries a contactspring 9 adapted to engage with the pin a when the lever is thrown to the vertical position.
  • This spring contact also serves to throw the lever out of contact with the pin when the handle is released and the latch f does not retain it.
  • Fixed to the base A are also the metallic parts 1 2 3 4. of a polechanging switch, of which '5 is the circuitcontrolling element, pivoted at the center and provided with two metallic insulated plates 72 and 2' S and 6 are the binding-posts for the wires of the charging-circuit.
  • h is a back-stop for lever g and is in circuit with an alarm 0 and battery 10, as will hereinafter appear.
  • the pole-changing switch-lever 1 is thrown either to the right or left. We will assume it to have been thrown to the left, as shown in dotted lines in Fig. 3. Then lever g is thrown to its vertical position to bring the two contacts 0 and g together.
  • the complete circuit will thus be established as follows: from post 5 to plate 3, bridge-piece 13',
  • the charging-current will then, however, be I directed through helix D, as followsrfrom i lever g to hook f wire 12, helix D, wire 13, throughithe battery and wire 10, as before. Some of the current may or may not still continue through the coil E in parallel. At all events the permanent magnet is now strong L enough to hold the hook in engagement with lever g until the'current for any reason ceases or its poiarity is'changed. In case the polarity of the current in magnetE in the first instance is such as to produce a north pole in i the pole piece above the permanent magnet there will bo a repulsion between it and the north pole of the permanent magnet and the hook wil i not engage lever g.
  • the winding of helix D is such that the cur-: rent traversing it will tend to strengthen the polarity 'of the permanent magnet, and thus insure the integrity of the circuit during the charging period. This vitalizing of the per-5 manent magnet during the charging period; also increases the permanency of the magnet.
  • I claim 1 In a charging-switch, the combination of a permanent magnet, a movable electromagnet having a pole within cooperative range of the permanent magnet, a latch carried by the electromagnet, and a circuit closing lover I adapted to be retained by said latch.
  • a charging-switch the combination of a fixed permanent magnet, a pivoted electromagnet having a pole within cooperative range of the permanent magnet, a spring nor- 7 mally restricting said pole, a latch carried by said electromagnet, a pivoted circuit-closing lever, a pair of contacts controlling the circuit of'said electromagnetpne of which is carried by said lever, the latch being adapted to engage the lever when the current flogws in one direction only. or r 3.
  • a charging-switch In a charging-switch, the combination of a permanent magnet, an electrical helix surrounding the same, an electromagnetmovably mounted and carrying a latch, a lever controlling the circuit of said electromagnet, and means whereby said electrical helix will be thrown into circuit when the current through the electromagnet is in a proper direction for charging.
  • a charging-switch the combination of 5 a permanent magnet, an electrical helix surrounding the same, a pivoted electromagnet 7 having a pole piece within cooperative range of the permanent magnet, a spring normally retracting the electromaget from the permanent magnet, a latch carried by the electromagnet, a lever controlling the circuit of the electromagnet and adapted to be engaged by said latch and a circuit extending from said latch through said electrical helix, substantially as described.
