SECONDARY OR STCDIELAGE BATTERY.

Application filed February 3, 15H5.

Zh eli when? t may concern.:

Be it known that l, BRUCE Fono, a citizen of the United States, and a'resident oi Philn adelphia, in the county oi' Philadelphia and State of Pennsylvania, have invented ce1"- tain new' and useful improvements in Seeondary or Storage Batteries, 'of which the following,` is a specification.

The principal objects oi the present invention are lirst, to lprovide ior steadying, or preventing lateral shifting of, plates in. respect to their container Without increasing the hazard of short-circuiting by sediment and second, to provide improved storage batteries for portable, vehicle, snbmarine and like uses.

rihe invention Will be claimed ollowing .e description of ,the invention which will be `given in connection with the accompany ingdrawings, in Which Figure 1,' is a side View, principally in, section.

Fig. 2, is a similar 'vieWWith parts broken away illustrating a modication.

F 3, is a similar View illustrating another modification, and

Fig. et, is a detail view of Fie'. 2, showing an additional niodiieationn in the drawings, referring more par ticnlarly to 2, l is a or.container9 as'of hard rubber, havinga rib 2 opstandn ing from its bottoni, and` forming sediment space 3. t, plates of one polarity having feet 5 arranged to ahnt on one i'ace oi the rib 1Q?. t5 are plates. oi' the other olarity haring Keet 7 arranged to abut on tie other of the rib 2. These.-4 eet cooperating with the rib obviously steady the plates.'

The capacity'ior sediment is limited by the distance between the bottoni edge of the and the bottoni of the containerl and seonaont may rise almost to the bottoni o e pla rithout bridging plates of n n like polarity and thus causing siiort-cirn cuits, the :ieet on one side oft the rib Si are ci one polarity andthe feet ont. e other side oi the rib 2 are of the other pothey may become embedded in sedi nient which will not produce short-cireuiting.

As shown in l, the jar l is provided with a pair of spaced opstanding ribs 2 and thev feet on the plates oi one lpolarity engage with the outer iace oi one rib whuiie the feet 'in oi'. the plates of the other polarity engage vwith the outer face of the other` rib.

ieceation of Letters Patent.

lPatented et, iilb Serial No. 5,627.

The plates oi' each polarity being 'thus held at their bottoms against shiitinfbr in only one direction, they may be prevented from shitting in the opposite direction'by the straps 9 and l() at their tops engaging the side walls oi the container. 'lhe operation is as has been above described and the arrangement is weil adapted for comparatively wide and low plates.

As shown in Fig. 3 each plate has two feet. The feet 5" oi' plates 'of one polarity cooperate with the adjacent faces of the ribs 2" and the feet 7" oi.t plates oi' the opposite polarity coperate with the distant faires oi the ribs Ik The tops of the plates may be held against shitting by providing a snug [it between the terminal posts ll and l2 and the cover lf3. .The inode oi? operation is as has been above described and the arrangement is well adapted for nar row and high plates. it' the jar is not of insulating material or lined With insulating material, insulating caps 8 may be applied to the feet as shown in Fign fi.

i/l is one oi" the separators interposed between the plates and which entends beyond the sides of the plates, which are narrower than the jar and the separator, so as to fit between the sides of the ln this way the separator is held against lateral shifting and since the plates are also heid against lateral shifting it follows that lthe projecting marginal portions of the sep( arators'. operate to prevent short-circuiting between plates ofY unlike polarity which inight occur if the edges ot the plates and separatorsnvers in alinernent. Moreover the bottoni or the jar being ribbed 'forms separated sediment spaces; the Apoint being that theprojections from yplates of unlike polarity ninst not extend into the same sediment space, as thesedilnent risinggto the projections wouldl canse ashort-cireuit be- Vfore the' entire sediment space had been the other Slgn l'engage the other face only thefrilol and those apperta'ining tol-plates o 0.
