To all whom it may concern: l

Beit known that I, JASPER N. DAVIS, a citi-zen of the United States of America, residing in the city and county of Denver and l State of Colorado, have invented a new and useful Battery Box or Tray and Handle Therefor, of which the following is a speci-fication. A

This invention relates to improvements in ignition storage battery boxes or trays and handles therefor.

The object of the invention is to provide a i wooden box having an interior lining of lead l and an outside jacket of the saine material, i which overla )s the upper edges ofthe box, g and is secured to the inner linino b v burning, j so that the box is elcctivelv. protected i a ainst the action of the sulfuric acid with Wich the battery cells are supplied, the lead being practically non-corrosive under the action of the said acid, thus providing a box which is not only strong and durable by reason of itsconstruction, but which is not weakened or eaten away by contact with the said acid. Further, to provide a box of this character, having hook shaped lugs whichl are burned to the outer jacket, and to which are removably attached a suitable acid- )roof handle, by which the battery can be lifted and transported without fear of break-A ing of the handle or lugs, and the consequent i injury to the battery, the metal used in the construction of the box being'lead exclu-I sively, which is practically impervious tothe action of sulfuric'. acid.

'In the accompanying drawings, Figure l, is a vertical, sectional view through the iinroved battery box equipped for service, the liandlc being in engagement with the hooked lugs, and partly broken away. Fig. L?, is a plan view of the box as shown in Fig, l, the compound which seals the cells being omitted. Fig. 3, is a sido elevation of a pori ion ofthe box, showing one of the hooi-:ed lugs, and an aperture in the outside jr-.cken rcgistering with the base of thc lug when the*` Fig. 4, j is a perspective view of a portion ot' the iuj side and outside jackets, showingthe lap seam where lthe jackets are burned together, l and the opening through which the handle lug ispasscd. Fig. 5, is a perspective vieu' of one of the handle lugs. nd Fig. l, is a. perg spective View of a portion of'oneV of the ends l of the Wooden box, showingthe recess in which the handle lug tits.

Similar numerals of reference refer to similar parts throughout the several views.

Referring to the accompanying' drawings, the numeral l, indicates a rectangulm` wooden box, of a suitable size, the uprner edges of which. are inwardhr beveled. Lilli g box is incasod in a lead jacket 2, which is of sulieient thickness to insure the requisite strength. The jacket 1s enough longer than the boxto lap over its upper inclined edges and entirely cover them, the corners ol the jacket being cut to forni initer joints as shown at 3, at which point the meeting edgesare burned together and thus securely united. An inner lead lining er jacket e, is nlaeed Within the box i, and this jacket is or a sise to fit snugly within the box, and ext-enel slight distance above the inner edge of the shown in the drawings, the extended. portion lapping edge of the outside jacket, to which it is secured by. burning, as'wnl be unde stood by reference to Fig. Il. By this conf` struction the wooden box is entirely incluse between the inner and outer j acl-rete, which are burned together so as to ret-'ent i. trance of the sulfuric acid usen in the batter Thebe thus free not only from the action the acid but from all other moisture as Well, is prevented from rotting, and conse-cp. retains its strength and rigidity for indefinite period.

ln connection with the improved style et battery box, above described, a suitable ha i dle is employed for liftineand transporting l[he saine, and it is essential that this handle, should be inane of material. that is inde structible under the action of sulfuric acid,

as it frequently happens that the handles. at

present employed are eaten away and therefor(` wrake ed to such an extent by the acid that they break and let the battery vtall, thereby causingr injuryto the said lfiat'tery. To overcome this detect, a handle 6 is einployed, which is made up of layers or sliects 7 of lead or oli lea-d webbing, the texture oi which is coarse enough to give the requisite strength. and these layers of lead or ot' lead webbing, are separated by layers o5 rubber, which also cover the outer sides and edges of the lead layers, completely einher li The lead layers merge into one the ends of the handle, or are lGU ous to the action of the acid, and therefore The hooklugs 10, to 1 not liable to break. which the handle is attached, have body portions 11, which are wedge shaped, as shown in Fig. 5, and the wedge shaped portions are passed through openings 12, in the overlapping edges of the ends of the outside jacket, and into corresponding recesses 13, in the ends of the box, these recesses extending,Y in

shown in Fig.

faces of the dy portions 11, to lie against 6, so as to permit the outer the outside lead jacket, as shown in Fig. 1, and the body portions are secured to the g jackets in the following manner: ik hole 14, Q

preferably rectangular in outline, and somc- -What smaller than the area of the body porlinadequately protected against the acid,-

tion 11, is formed in each end of the outer jacket, and in such a position that when the body portions are placed in the recesses 13, they cover the holes .14, as shown in Fig. 3. The edges of the aperture 14 are burned to the body portions, and the holes are then illed iusli with the surface of the jacket, by

placing pieces of lead in them and melting it. g

I hooks on the lugs and an acid proof handle having aperturesin its ends through which Y The edges of the openings 12, in the overlap ping ends of the jackets, are also united with the body portions of the lugs, by burning, l and the bodies of the lugs are thus securely united with the outer jackets, care being taken to make perfect joints so as to prevent the acid from getting Y The ends of the hand e through to the box. are passed under the hooked lugs so that the apertures 9 in the said' ends will be engaged by the hooks, for lifti or transportin thebattery, and the hand es can be quickly disconnected at any time, when desired. By this construction, the outer jacket sup Orts the weight of the battery, the Wooden xox being relieved of all Weight and strain when battery is lifted by the handle, and as lead. is the only metal used in the construction of the box, there is nothing that can correde under the action of the acid, and the danger of injuring the batvteries through partie es of corroded metal getting into the cells is thus entirely eliminated.

. Battery boxes in present use are unsatisfactory, irst because the Wooden portion is .which soon weakens it, causing the box to fall to pieces, and second, because metals are used in'their construction which corrode and are eaten away under the action of the acid, ,causing breakage and consequent injury to 'the battery, and third .because pieces `of y,corroded metal frequenti `get into the battery cells and injure the attery. The bat-S tery box herein described, by-'its construe: V' ingsiivhich registerwitecesses tion and material, eliminates these objeetionable features; besides requiring less time and care in charging them and keeping them in order.
