Application led laruh 13, 1911. Serial No. 614,068.

To all Lc/wm it may conca/'n Be it known that we, LAwnENcn Y. SPEAK and GRANT E. EDGAR, both residing 'at Quincy, Massachusetts, have invented certain new and useful Improvements in Battery Installations; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled Vin the art to which 1t appcrtains to make and use thev same.

The invention relates to primary or seeondary battery installations andmore particularly such as are used on marine vessels, railroad cars and automobiles, and it has for its objects, an improved form of tank to hold the battery, an improved' forni of ventilation to draw the gases from within such a tank, and means for automatically closing the Ventilating pipes upon submergence of' the tank.

In the accompanying drawings illustrating an embodiment of our invention, Figure l, is a plan view of the battery installation,

\ the cover being broken away to show the cellularq compartments within the tank; 2, is a sectional elevation on line 2.--2 of Fig. 1 and Fig. 3, is a sectional elevation on line Bf of Fig. 1, showing particularly the valves in the Ventilating pipes.

The box consists of an outer tank 1, and an inner tank 3 with an open space 2 separating the two on the sides and bottom. The outer tank is constructed of metal or other suitable material and is lined on the inside with suitable material 4, as lead, to prevent electrolyte from getting out of the outer tank and then corroding the iron parts of the boat or other supporting structure. The inner tank is supported on the outer tank by the transverse members 5 suitably spaced to rovide the proper support and bearing sur ace.

The inner tank 3 is constructed of wood or other insulating material and has longitudinal and

transverse partitions

6 and 7 respectively, which serve to separate the inner tank into cellular compartments for the reception of the battery cells 8. The

vtransverse partitions 7 do not reach the top opening of adjacent'partitions that air, pro` pelled through the ducts, must pass back 'and -forththrough the longitudinal ducts in porting structure is kept within the battery tank even when spilled .from the cellsI as the result of the rocking motionof the boat.

The outer tank is provided with a cover of the lon- 12 which sits tightly on the top gitudinal partitions and overlies the edges of the outer tank. An angle 13 extendsconipletely around the tank 4and is flush wit-h the top of the cover.- The cover is com` pletely covered with a sheet et rubber, oilcloth or other suitable Water-proof material 14 which forms a Water-tight joint with the an le 13 -when the battens or strips 15 are tig tly secured by clamps 16. '.lhe cover 14 1s cut out to allow the entrance of the ventilating pipes, but is lield down against the cover of the tank by the flanges which suis round the pipes to hold them in position. When it is desired tol uncover the tank, the Ventilating pipes are removed and the clamps 16 are loosened so that the hattens 4may be lifted. The cover 14 is then pulled otl' and the cover 12 is removed in sections or as a unit depending upon its construction.

Extending through the cover is an inlet pipe 17 and an outlet pipe 18. These pipes are at opposite sides of the tank, being on the same end if there is an even number of longitudinal ducts, and on. different ends it there is an odd number of longitudinal ducts. vThe air which is made to enter through the pipe 17 by any known means passes over the first longitudinal row of cells, through the first opening 10 in the partition, to the next row, and thence serially over the remaining cells to the outlet pipe 18. In this Way each cell is swept by the current of air and dangerous pockets of gases are avoided. Both the inlet and the outlet pipes contain a valve which is automatically closed upon submergence of the releasing mechanism. "When water covers the top of the tank to a sufficient depth, the float 19, rises and lifts the catch 20-in the chamber 21. The shutter 22 is then free to be closed by the action of the depending Weight 23. In this way the cells are entirely protected from the ingress of water, even upon complete sulnnergence of the tank. When'it is desired to close the valvein the inlet or outlet pipe, theloat 19 is manually, raised until the catch 20de out of engagement with the shutter 22. whereupon the shutter is -pulled down and held tightly over the .pipe b v the weighted Varm 23. To open either of the valves, the weighted arin 23 is lifted by hand until the shutter 22 is caught by the catch 20.

Having thus described our invention what we claim is:

1. In a battery installation, a battery tank, a plurality of rows Ofbattery cells 1n said tank, a cover for`said tank, air inlet and outlet pipes passing into said tank, and partitions between the rows of battery cells reaching to said coverand having openings at alternate ends only so that the air ducts over said cells are in series throughout their length between said pipes.

2. ln a battery installation, a'tank for bat- `iery cells, and a water-tight cover for said tank, said cover comprising a part covering the tank in such manner as not to exclude water, and a water-proof part extending over the edges of the tank, bat-tens on the \\'ater-'proot' part extending completely around the edges of the tank, and clamps adapted to hold the battens tirinly in place in order to prevent the entrance of water between said cover parts at the edges ofthe tank upon submergence thereof.v

3. ln a battery installation, a tank for battery cells, a cover for said tank, air inlet and outlet pipes through said cover, and longitudinal partitions in the tank reaching to said cover and having openings at alternate ends only so that the longitudinal air ducts over said cells are in series throughout their length between said pipes. l

4. In a battery installation, an inner tank for battery cells, an outer tank, a space between said tanks, a cover over the outer tank, air inlet and outlet pipes through said cover, and longitudinal partitions in the inner tank reaching to the cover and having openings at alternate ends only so'that the longitiulinal air ducts over saidcells are in series throughout their length between said ipes.

5. In a battery installation, an inner tank v containing battery cells closely fitted therein, an outer tank, a space between said tanks, a cover over the outer tank, and an opening from the inner tank to the space between the tanks whereby electrolyte spilling from the cells collects in the space'between the tanks.

6.,In a battery installation, a tank for battery cells, a water-tight cover over said tank, air inlet and outlet pipes through said cover with a water-tight joint, and ay sealf and close to said cover, whereby the tanklmay. be

ing valve located in each of said pi etectuallysealed from -withoutfji 2i." s

`7.1-In` a-"battery installation, a tankfor battery cells, a water-tight cover. over said tank', air inlet and outlet pipes through said cover with. water-tight joints, and sealing valves having releasing mechanism adapted to automatically close both of the pipes against the entrance of water upon submergence of thetank.

8. In a battery installation, a tank for battery cells, a water-tight cover over said tank, air inlet and outlet pipes through said cover with water-tight joints, and a sealing valve located in each of said pipes close to said cover and having releasing mechanism adapted to automatically close the pipes against the ent-rance of water upon submergence, and a weight adapted to hold the valve eifeetually closed.

In testimony whereof we aiiix our signa' tures, iii presence of two witnesses.
