To all whom it may concern:V

Be it known that I, GEORGE W. HARRIS, a citizen of the United States, residing at New York, county and State of New York, have 5 made a new and useful Invention in Storagelo having large active surface with low internal resistance. Second the construction of an electrode which shall possess minimum Weight and greatldnrability, ears or bindingA posts manner as to give increased strength to these parts and electrical resistance. x

To these ends my invention'consists tirst in the novel 'method of construction hereinafter. 2o described and claimed. Second in the novet electrode constructed in accordance wlthsaid l method.

in` `1order understood by that my invention may bef;fully those Skilled in the art refer-` ;25 'ence is had to the accompanying drawings takenn connection with the following description thereof. l

P P are sheets of blotting paper, fabric, er any other equivalent prousor absorbent non-conducting material ofjsligbtly great-er length than the activefodlead plates l?, as shown'in Fig.`3, and'of a width-sufficient plates P of whichthe lectrode 'sgformedto lit snugly between 'the cleats'D D in the box or former.

.C is a strip of cloth or analdgoiis material adapted to secure the parts ot the electrodo .tOg'hl afteritis completed.'

F F represent the .completed faces of the electrode, and E and E thelf,.conducting ears or lugs of large surface preferably .securedto the faces F and F by solder around the edges and in the holes H. band b are the binding screws for connect-l ing. the completed elements in circuit for charging or discharging.

p 10,-;Fig.. 1, are forming wardly extending heads 71, the functienof these pins being to separate the extended pins with downedges of the lead `plates P and to aid in' turnl ing said edges over 'as shown on the right in Fig. 4t. e 1

. My novel method of construction is as fol'- lows. A strip of cloth or analogous pliable non-conducting material'4 of good tensile strength and preferablypossessing absorbingI qualities, and substantially of the width of the completed electrode, isv laid in the boxer former B with its ends projecting in-.the man;

ner shown in Figs. 1 and 3,tl,1e length of thgs-` i Strip being Sufficient .presentaremos-ftd a v the completed electrode'fn the manner shown in Eig. 4, where the ends are shown as stitched together. l then lay one or more sheets ofb blotting paper of equivalent non-condncting absorbing material P upon the cloth in' the 4bottom of thel box or former the inner end r" vends projecting against 'the cloth atthe rear end'of the box or former'and tting snugly between the cleats D Q,.the sidefs'of said?V y blotting paper being parallel with the sides' of the box or former. I next place upon the sheet or sheets of blotting paper thus dise width and lessi-length than theb: ottingpaper 'Irc o` osed a thin sheet of lead of slightly greater"- in such manner that its inner end Arests against one of the cleats l) andoue lateral edge bears against one of the lateral inner faces'of the box or former l. I then place another layer ofl blotting paper upon this. sheet of lead and then an additional sheet of lead upon this blotting paper as before; in this instance however, the other lateral edge of the second plate l is caused to restagainst the other ,lateral inner face of the box or former. Alternate layers of blotting paper and sheets ot lead are thus disposed until the box or former is i'illed to the desired depth; the laterale projecting edges on one side constituting the terminals to be united as l one element or pole of the 'electrodel and the like projecting edges on the other side constituting the terminals for the other element or pole.'(see Figs. 2 and -l).-. I then draw together and firmly unite the ends of the cloth strip orfabric G, by stitching (see Fig. et) and carefully remove the electrode from the box or former, after which I place it between clamps. 'While the lclamps are thus in positionIinsert long metallic pins p provided with heads or handles 7i., between the projecting edges of the entire set of plates l onone side and iron or otherwise turn down these projecting edges in the manner shown on the right in Fig. 4. The pins j; are then drawlr out by the aid of the haudlest, and inserted between the projecting edges of the plates pn the opposite side, and these edges are ironed or turned down in a similar manner, it being obvious that great care should be used to leave a sufficient space at the opposite edges .0f the electrode to prevent any possibility of short circuit between the individual plates of each element. These wires may be of leadl andinay it' preferred be left in position thereby affording a more com pactl y formed mass.

The edges having all been turned down as described, I then unite them in one solid orintegral mass by soldering, llead burning, or in any manner which may readily suggest itself to those skilled in metalworking. I then prepare ears or lugs E Eof the necessarydiinensions for conducting the entire current which the battery is capable of receiving anddischarging andunite these ears to thefaces F F by solderingor lead burning them thereto.

I prefer to make these ears of tapering or Wedge shape and of large area, as shown, and to perforate them with holes H for the'purpose of receiving the solder and atording a' firm and sure metallic union between all parts of the ears and the faces F F.

, The electrode as thus constructed constinary rough usage without damage.

A tutes a single or complete electrode bound togctheron all sides andthercfore read-y l'or transportation and use as a completed article which may be subjected to more than ordi- It slight,

-,durable, of 4very lon7 internal resistance, and

.notsubject to local or short circuit action.- 'lbvocl''incitent` such electrodes maybe united together in series or multiple are relatonini l my preferred manner, either by .uniting the binding screws bb of such electrode in any ef the usual ways, or two 01' more electrodos may be joined togetherin a single large cell by uniting the faces PLF on one sido in any desired -wa-y, such matters beingy obvious to. those skilled in the art. Y

rllic electrodes as Ythus constructed are placed in battery cells or jars in anyol' the Qwell known storage battcrysolutions and are 'cha-rgedwlrile in this condition in the usual manner, it being necessary before commencing the charge that they shall stand'a suliicient length ot' time in the solution to allow it to thoroughly saturate the intermediate sheets ot blotting pape as will be readily understood by those skilled in the art.

After the electrodes have been formed by charging, discharging and recharging after the manner of forming Llant cells they are ready for future use and transportation and their compactconstruction is of such a nature ,that they are not readily subjected to damage eitherin transportation or nse,la'nd they may be charged and hold the charge put'into them for months without deleterious results,-

even though removed tion.

I ainaivare that it is old in the art to construct a storage battery cell of aiternate thin sheets of lead and blotting paper-,land Intake n'o claim broad enough to include such a structure.

Having thus' described my invention, what I` claim and desire to secure by Letters Patent of the United States, ist* 1.

2. The described method ot constructing a storage battery electrode consisting in pililig together alternate sheets or strips of lead and -an absorbent as blotting paper, the opposite edges of alternate sheets ol`4 lead extending beyond the edges of the corrcspomfli ng edges of the intervening sheets ol blotting paper and from the charging solufinally uniting all of the edges into'two independent integral faces.

The described vmethod of constructing a IlO IIS

storage battery electrode Yconsisting in intcrleaving overlapping alternate ducting material adapted to become active under a charging current, and absorbent nonconducting material and then. unitingr the overlapping edges ot' the conducting material on opposite sides into integral faces which constitute the poles of the electrode.
