Be it known that l, FERDINAND PAUL.
BAUMAXN, w citizen of the Swiss Confed (,l'tl lfil'l, 1Gi '!\'liil at .ixiisnucht, Canton Zurich Switzerlanlil, have. invented new and.
useful in: iroven'reuts in Dry Batteries, of 'which the ffOll-DWJIlg is e specificetwn.
The invention relates to dry batteries of the kind in which the electrodes of each couple are in the form of plates between which the electrolyte is confined, The novei feature of my invention consi :s of 23, l'mttery in Which euchcouple comprises a carbon plate and st metallic plate arranged face to face, with a cavity located. between them, 111 which :1. soft electrolyte 1S confined the carbon late hnvin its ex tci'ioi' face impregnated with it fills? which enters-the poi-es kit the surface only, sniil iimpiegi'lzited face being also provided with a metal frame or covering adapted to rest against the negative electrode of the next Reference is now had. ing' throwing, in which:
Figure l is :i fractional front elevation, and 2, a. vertical section of one form of my hnm-oveoi dry battery.
in this form of battery, shown by oft examplqit is presumed that the elemei'its in. respect of materials are built on the l'uclanchc system. The hatter is composed. (if-three couples of piste-electrodes. The positive electrode as consisting of s mixtme'oif nmhgsnese ilioxicl and graphite, has on one (l6 the cm ity siu'rounrlerl by :1 hoifclei' r: to which is applied an insulating layer (1. In the iv 7) of each element is fillerl a, nasty electrolyte (2 containing arm to the acconn pony moniosolution that is to ammonium l'i nlroirirl, soiil electwolytebeing flush with. the surface oi the insulating layer (Z. )n the opposite side to that having the cavity snitahleflepth in the pores with -:i fillingsnhstance or mass f such as pz rafiin. The
through to the opposite side.
vzmic manner by deposition, to form a coat ins; of good conducting material, for exam ple copper, applied sons to estehlish intimate contact between the carbon eiecti'ode of the oneelement and. the zinc of the adjacent eleme'iit. f Each element comprises,- sclja'cently to electi olyte e and insulating layer a negative z1nc-electr0de it.
three" couples forming: the battery For keeping the battery securely together a non-conducting sheath 1S pi'ovicleci which may be of paraffin for example. The finisherl. battery forms 21 compact hotly and can be easily introduced in any electric ci?:- cuit. 4
The improved battery has, in. comparison with the, usually known batteries. the eelvan'tzigc of being easily and cheapiy menus factored. The same is especially itdi'iil'ltzigeous for pocket lamps, these being hitherto Furnished with batteries of meye or less (lifiicolt construction requiring; great care and accuracy in fitting and imposing an elevoted price for the lamp.
I claim:
A airy battery of "the hint? halvingplate electrodes of which the carbon eiec trotles' are impregnated with impervious -stances is made to form on'fy a omplete surface filling layer in? the pores smi :2 mete] 'i'mme applied to impregnated face of eec carbon electrmie to serve fjfilifl contact portion with srljacent negative, electrode.
2; fihattery comprised of a plurality of electrical couples each. consisting of carhon and a metal electrode in flat plate form arranged face to face, onev oi the electrodes having! a cavity on its face against which theothejr el-ectiofie is presented sci-iii cavitycox-hon clec- I the ccmtsining electrolyte,

The coverings- 3. A batteryunit comprising a carbon electrode in plate form,- an opposite metallic electrode also in plate form and arranged against .one face of the carbon plate but'insulated therefrom, a cavity being provided between said plates .an containing an electrolyte, the carbon plate being impregnated throughout its exterior face with an impervious filling which penetrates the poles ,at the surface thereof only to which face is also intimately attached a metal 00V,-
