STORAGE-CELL.

Specification of Letters Patent.

. Patented Aug. 12,1913.

Application filed August 1, 1912. Seria1No. 712,653. 7

To-aZl whom it may concern:

Be it known that I, AUGUST O. KRononR, a citizen of the United States, residing at 7 45 Hubbard v street, Milwaukee, in the county of Milwaukee and State of (Viscousin, have invented anewand useful Storage- Cell, of which .the following is a specification.

My invention relates to storage cells, by means of whichas commonly understoodelectrical energy is stored for future use.-

The objects are, to furnish a storage cell of higher efliciency and greater power, but less liable to injurious chemical action, than To attain these objects I use antimony electrodes and a saturated hydrochloric acid solution of compounds of antimony and chlorin, preferably antimony trichlorid, as the electrolyte. By using these, equally good results may be ob- I tained regardless of any one particular de-' sign or construction of the cell, providing the general rules and principles, pertaining to storage battery engineering, are observed. Hence I do not limit myself to the precise construction, asillustrated in the accompanying drawing and herein following de-, scription thereof, wheiein- Figurel is a vertical section of the entire storage cell, as indicated by the dotted line 0-0 in Fig.2, which is a top view of the cell; Fig. 3 is a cross section through the entire cell, as indicated by the dotted line B-B in Fig. 1;. Fig. 4: is a full size section of part of one of the twenty-four antimony plates P, that constitute the electrodes, showing that part which slides over the connecting rods S or S, andpart of the grooved surface; Fig. 5 is a cross section of the cupshaped upperpart of the glass rod L, as indicated by the dotted line -A-A in Fig. 1.

The containing vessel 0 is made of glass, and has three circular cavities in the bottom 'to hold the two antimony connecting rods S S and the glass rod L in place, as illustrated in Fig. l; the cover K is also of glass and firmly screwed to the containing vessel 0 by means of the six bolts N.

' The twelve antimony plates, that constitute the positive electrode, are connected and held together in a horizontal position, by sliding one above the other onto the ant-imony rod S, interposed by the twelve antimony plates that constitute the similarly constructednegative electrode with the antimony rod S, as illustrated in Fig. 1; the glass rings R (marked in Fig. 3 only) separate the positive and negative plates from each other, and also serve as supports for them. In the center, through the plates and rings, is placed the glass rod L, which terminates at the top in a cup form, so as to permit the funnel-shaped extension in the center of the cover K to slide into it, thus holding it in place and preventing the plates and rings from shifting; J J Q I are rub;

ber bands.

The glass stopper F can be removed by releasing the brass spring G, for the purpose of filling the cell with the electrolyte; the four holes M, as illustrated in Fig. 5, permit the liquid to pass through as indicated by the two arrows in Fig. 1; the dotted line E-E indicates the proper height for the electrolyte.

The binding posts 1) D are of brass, and form the terminals of the cell; they are screwed to the antimony caps H H, into the two circular holes in the cover K; the antimony rods S S connect with the antimony caps H H by sliding into them when the glass cover K is screwed in place, thus formmg complete connections, 'as' illustrated in I vFig. 1.

Each antimony plate is perforated with sixteen holes, as illustrated in Fig. 3, to allow a more free circulation in the electrolyte. To offer a good surface for effective electrolytical action, the plates are grooved on both sides in a checkered manner, as illus- At the N egati've Plates.
