Definitions

  • the invention relates to an electric accumulator for the storage of electric energy,'which may be used for example in motor cars and the like.
  • the well-known accumulators comprise cells the plates of which can only be removed with difficulty and with a considerable risk of damaging the pasted plates, making inspection and care of the interior impossible for those not skilled in the art and having no special equipment.
  • the deposit accumulating in the cells, and which may be considered the principal 'cause of interior short-circuits is-diflicult to remove, and flushing appears to be of little effect, in practice, for removing the impurities on the bottom and those between the plates.
  • the invention relates to an electric accumulator having a cover from which the plates are suspended, the plates being arranged in a jacket entirely or partly open at the bottom and constructed as an inner tank placed within an outer tank or vessel which holds the electrolyte.
  • the accumulator is characterized by the fact that the Walls of said inner tank near the upper parts are provided with outwardly protruding ribs forming, together with corresponding ribs of the inner wall of the outer tank and the upper parts of the walls of both tanks, a gutter-shaped space which may be filled up with a sealing material.
  • inwardly protruding ribs can be arranged on the interior of the walls of the inner tank near the upper parts, the cover of the accumulator being supported by the said ribs, whereby the joint between them may be covered by sealingmaterial.
  • Fig. 1 is a fragmentary section on one corner of the accumulator showing how the various parts can be scaled up.
  • Fig. 2 is a side elevation of one of the cells of the accumulator, partly in section, and
  • Fig. 3 isan elevation of part of the accumulator, at right angles to Fig. 2, showing one of the cells partly in section. 5
  • the inner tank composed, for example of a moldable insulating material, which in this case has perforated side walls, whereas the bottom side is open; this bottom, however, can also be constructed only partly 10 open. If necessary the side walls could be provided with ventilation openings.
  • the said inner tank houses a group of plates P and is supported upon ridges 6a on the bottom of an outer tank 4, with a free space between the side wall of the 15 inner and outer tanks.
  • the inner tank has in- .tegral handles 2 whereby it can be removed from the outer tank.
  • ribs 6 Fig. 1 which are directed to- 20 wards each other and arranged on a level.
  • both ribs 6 form the bottom of a gutter-shaped space the upright walls of which are formed by 5 the upper parts of the walls 01 both tanks.
  • the said gutter-shaped space may be filled up with a sealing-material such as bitumen, pitch or the like, or with a strip of rubber, in order to bring about a perfect closing.
  • the walls of the inner tank can also be provided with an inwardly protruding rib 1 receiving the edge of the cover 8.
  • the edge which is formed in this manner may also be closed by a sealing-mass 5. It is also possible, however, to 35 make the cover so that it forms one unit with the inner tank.
  • a group of plates In an electric accumulator, a group of plates, a cover from which said plates are suspended, a 40 jacket surrounding said group of plates and at least partly open at the bottom, said cover being supported upon said jacket, an outer vessel surrounding said jacket, said jacketand vessel having ribs projecting, respectively, outward and 45 inward just below their upper edges, and means in said outer vessel supportihg said jacket so that its rib stands in non-overlapping relation at the same level with the rib on said vessel, to form a gutter bottom for receiving a sealing 50 material.
