Abstract

219,769. Doe, W. S. May 29, 1923. Absorbents; treating electrodes to prevent local action; electrodes; electrolytes; connections; connections to carbons.-Each cell of a dry battery for flash lamps &c. comprises a carbon pan 25 containing a depolarizing mixture which may consist of carbon, graphite, manganese dioxide, peroxide of lead, glycerine and tragacanth. The top, sides, and ends of the pan are coated with insulating material. Resting on the depolarizer is a layer of absorbent material such as blotting paper, 19, moistened with a solution of ammonium chloride and bisulphate of mercury and then dried. The dried blotting paper is secured to the lower surface of a zinc plate 15 by means of a cementing material 20 applied to the edges. The upper surface of the zinc plate is coated with varnish or other insulating material and is provided with struck-up protuberances 18, the points of which are bare and make contact with the under side of the superimposed carbon pan 25. The battery is held between contact plates 30, 31, the plate 31 having protuberances 32 which bear against the lowest carbon pan 25. The battery is activated by dipping the zinc plates 15 and linings 19 in water, and when exhausted can be regenerated by renewing the zinc plates and depolarizing mixture. Fig. 1 shows the battery in use with a lamp. The plates 30, 31 are provided with flanges 33, 34 as shown in Fig. 2 which are fastened by binding posts 35, 36 to the cover 11, the post 35 being in electrical connection with the outer terminal of the lamp. The post 36 is brought into contact with the central terminal 53 of the lamp to complete the circuit by means of a disc 50 which rotates about a pin 51 which connects the lantern to the cover 11 and makes contact with the central terminal of the lamp. The post 36 passes through a slot in the disc 50 which when rotated brings the end of the slot into contact with the disc and completes the circuit. A mica &c. plate 60 is interposed between the battery and a flange 61 on the cover to prevent short-circuiting.
