To all whom it may concern:

Be it known that I, HUGH Lnsnnr, a citizen of the United States, and a resident vot' Philadelphia in the county of Philadelphia and State oi Pennsylvania, have invented useful Improvements in certain new and v Storage-Battery Tanks, of which the following is a s ecification. ()bjects o the resent invention are to prolong the life 0 the wooden tanks and their supporting battens and ,this object is accomplished according to the present invention generally stated, by providing cilicient, comparatlveiy inexpensive and reliable means for directing the dripclcar of or away from'the arts of the tank and battens, if present, w ich are most susceptible ti) the corrosive action of the drip. 4 The invention will be claimed at-the end here'of,.'butwill first he described in connec tion with the embodiments, but not the only embodiments, of it chosen for illustration in the accompanying drawings, inwhich- Figure I-is anelevationalview with parts broken away illustrating a tank :and a art of a second tan-k1embodying-features o the l "'Figlvfl', is side view with "roken away illustrating a modifica- 'ent1on. ;j ingsI-l is the lining as of lead iiich isconstruetedrof wood. 'irbattenronwhich. the't'a'nk may be ieii the b atten is present it supported'a'nd I may inst upon insulators 4-.

o .e p orts or blocking-pieces that are sometimes interposed hctx'veen the walls of adjacent tanks so as to oppose their bulging, by reason of the weight u'li the liquid which they contain.

At the'to the'lining 1. projects downward and outwarc all around the top ofthe tank, like the caves of the roof of a house. The object of this is to cause electrolyte to drip so far as may be, clear-of the wood; it being understood that electrolyte attacks and dis- Even with this provision, electrolyte dripping from the outwardliy and downwardlyprojecting part-6 of the ining is apt to fall upon the blocking pieces 5 and in that way reach the outside of the wooden walls of the tank and collecting between these walls and the ends of the bl ocking iece attacks the wood. Furthermore if the tank be not perfectly level the drip occurs principally at the corners and is by drafts of wind or other causes blow-n against the corners of the tank and since at the corners the end grain is exposed at the dovetails, the electrolyte reaches the end grain which is peculiarly susceptible to attack and corrosion. hen electrolyte drips from the corners italso reaches the ends of the battens 3 and attacks their end grain in a similar manner. To avoid these defects and disadvantages the edge of the turned-down por tion 6 'ofthe lining is furnished with a se ries of indentations 7, so that the drip occurs at the points 8 between these indentations-and these points 8 are located ingsuch a .wayas notto discharge their drip onto vulnerablepar'ts of the tank, for example, the points are located between the blocking ieces 5 and not at the corners of the tank so that the. drip falls between the blockingpieces and to the sides of the corners and is thus directed to positions where it does the least possible harm. Furthermore, the insulators t are so positioned with respect to the indentations 7 and the points 8 that the drip "from the latter does not fall upon the insulators and thereby lessen their ellii'ciency.

The construction and mode of operation of the deviceshown in Fig. 2 are as above described. with reference to Fig. 1, with the exception that the edges of: the lining atthe indentations are curved upward as at J, forming gutters which discharge at the oints 10.

What I claim is:

1. A storage battery tank having a lining which projects outwardly and downwardly from the top of the tank, and the edge of which is angular to the top of the tanlq'to direct the drip,'substantial1y as described.

' 2. A storage battery tank having a lining which projects outwardly and downwardly from the top of the tank, and the edge of which provided with indentatihns, the projecting portions of which direct the drip, substantially as described. I

3. A storage battery tank having which pmjoc-ts outwardly and downward] y from U10 top of the tank, and the edge of which is provided with indentatinns, lmvi 11g gutters ind the projections of said indentations serving to direct drip, substardially as described.
