nnmonm BATTERY.

Be it known that I, ALFRED RORDAME, a residing at Salt Lake City, in the county of Salt Lake and State of Utah, have invented certain new and useful Improvements in Dry-Cell Batteries, of which the following is a specification.

My. invention relates to dry cells for gencrating electric current, and has for its object to provide a dry cell which will prevent ving a the escaping of the energizing paste thereof from between the bibulous liningfand the container and hold the said energizing paste in place when the chemical chan es occur, which, changes must take place w en electricity is thus generated, and-will prevent said paste, from escaping over-the sides of the container, the forming of short circuits and the rapid deterioration of the cell. These objects I accomplish with the device illustrated in the accompanying drawings in which similar letters of reference indicate like partsthroughout the several figures, and as described in thespecification formpart ofthis application and pointed out in the-appended claims.

.In said drawings Figure 1 is an elevation of one "of my cells, with. parts cut away, and piu'ts' Show? in .vertical fSGgiOIIJ Fig. 2kis a p a view 0 .a portion 0. t e screen pac ing.

'li filmells gs usually constructed the energizingpaste' {soften forced from between thebibulous'lining and the metal container, by certain gases which are liberated by the chemical action generating the electric current most casessaid Paste lwill be thus forced, by said gases, between the sealing means and the container and will flow over thesides of said container andsoak into the insulating jacket around the cell and establish an external short circuit when said saturated jacket comes in contact with other saturated ackets of adjacent cells, "similarly constructs and likewise afi'ected- In this "ay' a piunib'er of adjacent cells will be {quickly ruined,

My invent-ion consists more specifically in 1nt 9rposmg between the metal. container and ,ghulous lining,*an insulated screen 1ng, having interstices obliquely dis- In this way the bibulous ling d;.the'enrgizing paste is forced Specification of Letters Eatent.

to fill said space in said interstices and around said screen packing. "he purpose of so spacing the bibulous lining and metal container.

Referring now to the drawings: the container 1', is made of zinc preferably as a cylindrical cup with open top. A screen packing madeot two or more telescoped cylinders 8 and "9, constructed of coarse mesh screen material, made of cotton netting, which has been dipped into plastic celluloid, rubber or other insulating material, is placed within said container, with the interstices obliquely disposed and filled with the energizing paste 10. A simple and convenient method of making said cylinders and placing them in position to form the packing is to construct the cylinders of coarse cotton netting and dip them into the insulating and stifiening paste, and when said paste is dried, to telescope one within the other and move one on their common axis, so that the-openings or interstices in the ,walls of one cylinder will not be .in alinement. with those of the other cylinder, to form a rigid noncompressible packing having a great many openings in and through its wall. The usual bibulous liniiig 2 is then inserted with a portion thereof upstanding above the walls of the container. The usual carbon electrode 4 is centrally, placed in said container 1 and the depolarizing battery mixture 3 is tightly packed around said electrode 4 filling the said container to near the top. The bibulousliningQ isturned over on The, usual abtop of the battery mixture. sorbent 6 and sealing mixture 5 are then put in place to fill said container. The insulating jacket or outer covering 7 is secured on and around said metal container. As will be obvious-the pressure of the generated gases on the bibulous lining can not force the "energizing paste out of the space between said lining and container and any tendency to move said paste upward will be prevented by the screen packing; and the paste will he held in place during the Whole life of the cell.

Havingftlms described my invention l desire to secure by Letters Patent, and claim 1. A dry battery comprising :1 nine container; :1 pecking therein composed of coarse mesh insulated screen cylinders with the interstices in staggered relation and filled with energizing paste; a bibulous lining Within the inner of said screens; a centrally disposed electrode; a battery mixture between the electrode and said bihulons lining; and [L seal for said container.

2. A dry cell battery COlfipl'lSlIU n. zinc container; a plurality of course mesh wtttm netting cylinders onewithin the iithdl with the interstices out of radial elinement; 21E energizing paste in the interstices ei set netting; a cylindrically shaped bitfuleue 11n= in g within the inner of said cylinders; e we ti-ally placed electrode; at battery min be tween said electrode and said bibelcus 1in= ing; and a sealing means for mid centsiner.

In testimony whereof I have altered my 2 signature in presenceot twewitnessee.
