sncoNnAnY on STORAGE BATTERY.

i' following is a specification.

V has a beveledl lug The principal object of 4the present invention is to cheapen, improve and facilitate the connection by burning between adjacent cells, and between the bus bar and thesplate lugs avoiding the use of forms in the burning voperation and obtaining an excellent Contact. p

The invention will be claimed at the end hereof, but will be first described in connection with the embodiment of it chosen from among other embodiments of it for illustration in the accompanying drawings, in whichl Figure 1, is a side view, partly. in section, of so much and such parts of a storage battery as are necessary for an illustration of the invention. Fig. 2, is a perspective view of a plate shown in Fig. 1, with parts thereof brokenaway. Fig. 3, is a top or plan view of the construction shown in Fig. 1. Fig. Il', is a top or plan view illustrating a modification-of the invention in which the bus bar is not employed, and Fig. 5, is a view similar to Fig. 1, but showing the modification vof Fig. 4. I

'In the drawings l, is a bus bar having a beveled face or perhaps more accurately two beveled faces 2 and 3. Each plate 4,

5,l extending laterally beyond the faces o thesplate.

6, is a metal lling which is co-extensive` with the lugs ofthe plates and connects them with the bus'bar l. l In use the plates are mounted 1n a tank or I container 7, and are properly supported therein, for example, by a support 8. The lugs of the plates by reason of their width contact with each other at each end of the tank. More accurately, the lugs of the v alternate plates contact with eachl other vat each end of the tank. The contacting lugs of a number of plates are made to touch the side of the bus bar l. The beveled face of the bus bar and the beveled faces of the lugs constitute along continuous groove 9, shown `Speciication of Letters Patent.

application mea nay 1e. 1913. serial No. 767,977.

1n Fig. 3. By burning and puddling this groove 9, is filled with metal 6, thus connecting the bus bar and lugs. Puddling is the term applied in the art to describe the operation which consists in burning or joining two pieces together While applying molten metal to the joint. It may be said to be something like soldering but the metals are usually all the same, whereas inV soldering or brazing the applied metal is oftendiferent from the other metals. Since the groove is continuous, forms are not required and the assembling operation may be performed rapidly, successfully and comparatively inexpensively. i

In the modification shown in Figs. 4 and 5, the construction and arrangement are as above described, except that the bus bar l is omitted and the lugs 58 of the plates are of appropriate length. For example, they may be somewhat longer than in Fig. 1. The metal 6a is puddled into the groove 9, which, however, in this modification is constituted by the opposed beveled ends of the lugs 5.

The invention is not intended to be limited further than the prior state of the art may require, but f What I claim as new is:

1. In a storage battery the combination of a bus bar having a beveled face, a piurality of plates each having a bevel-faced lug extending laterally beyond -the faces of the plate, said lugs adapted to Contact laterally with each other forming with the face of the bus bar acontinuous groove, and metal illing said groove to burn together, substantially as described.

2. The combination in a storage battery of a plate of one polarity, plates of opposite polarity arranged on opposite sides of said late and each of the last named plates' the partsl tends laterally beyond its faces, the lateral extensions of said lugs being substantially in contact to form a continuous groove section for puddling purposes.
