Specification of Letters Patent.` Patented Man 9, 1920.

Application led November 27, 19.18, Serial No.v 264,344. Renewed Liovember 17, 1919. Serial No. 338,536.

State of New York, have invented certain.

new and useful Improvements inStorage-l Cells, of which the following is a specification.

This invention relates to storage batteries and a major object is to provide a storage cell in which eachelementcomprises a series of plates arranged radially or otherwise at an angle to each other and substantially in thearea of a cylinder to increase the electrical capacity and eiicienoy of operation.

Another object of the invention is to pros vide a storage cell embodying a central or positive element having a series of angularly disposed plates connected at their inner edges adjacent their base by the fusion of a plug thereto, and at said inner edges adjacent the top by the fusion of a post thereto which serves as a binding post or distributor of the current.

Still another object of the invention is to provide a storage cell embodying av negative element composed of a series of angularly disposed plates each having an upstanding lug connected as by fusionv to a ring or connector common to all of them which serves as a binding post or distributor of the current.

A further object of the invention is to provide a battery jar having an upstanding supporting bead lfor the elements, prferably unconnected tothe wall of the jar and also preferably being curved so as to permit and facilitate play ,of the sediment which forms and reduce the chances of its formation in masses which short-circuit the battery. t.

A still further object of the invention is to provide a novel` separator means to prevent contact between the positive and negative plates of the element andto reduce the chances of buckling thereof` and a form specifically coperating with interfitting radial plates to receive a plate; of one polarity and be braced against onel or more plates of the opposite polarity.

Another object is to provide the elements of such a construction that one of them will be supported by the other in assembly, to

facilitate `their handling.

Again an object is to provide an endless or rmg connector for one series of plates and a connector for the other series of plates adapted to extend through the ring connector in spaced relation thereto.

In addition to the foregoing, it is an aim .to provide the additional specific improvements which will become apparent as the followmg description progresses in relatio to accompanying drawings.

In these drawings, similar and corresponding parts are designated by the same characters of reference throughout the views in which they appear, and

Figure 1 is a view in vertical section of a storage cell constructed in accordance with my invention and taken on the line a-a of Fig. 4;

Figs. 2, 3 and 4 are transverse sections respectively taken on the lines 22, 3-3 and 4-4 of Figfl, and

Fig. 5 is a view in perspective of the novel form of separator employed.

With reference to the drawings, 10 indicates the containing jar, of hard rubber, glass or other suitable material, which is preferably cylindrical, open at the top and ranged to substantially occupy the area of a cylinder being preferably spaced from each other at the inner side edges, except at their base where a plug 13 is fused thereto and at their upper ends where a post 44 is fused to them. Itis understood. howeverA that said plates may be connected together for their entire lengths. if desired, or their grids made integral. Post 14 stands upwardly through and bevond central openings in an inner cover plate 15 and an outer Vcover plate 15a, sealed together and to the jar-by a rubber or other fusible compound 15b to form a closure for the jar. In practice I prefer that this be the positive element, although it is obvious that it may be of opposite polarity if considered desirable. Referring now to the other element of the battery, it also consists of a series of radial plates arranged substantially in the area of a cylinder. These plates are designated 19 and each one is provided at its upper end adjacent the outer side edge with an up standing, preferably integral, fusible lug 20, and the lugs 2O are all connected together by means of a fusible ring 21. A post 22 integral with the ring extends through an opening in the cover plates andla. This element I prefer to form of negative po, larity. A

The plates used are preferably of the Faure or pasted grid type, and they may be manufactured and assembled in accordance with my constructions and processes set forth in co-pending applications filed November 27th, 1918, and bearing Serial Numbers 264,345; 264,346, and 264,347, respectively. In dis osing the plates of the two elements in sullstantially cylindrical formation and alternately of different polarity, the elements are placed with their longitudinal centers in alinement but with the plates disalined and the base of the negative element opposite the top of the positive element, and the elements are then moved longitudinally towardpeach other. As the negative plates are connected merely by means of the ring, their base ends are separated and free to slide between the positive plates. Since the positive plates underlap the said ring, they will engage the ring at their upper ends, as the positive element is lifted, say by the post thereof, which is advantageous in assembly. By way of example, the parts of the elementare made of lead. As usual too, the elements are electrically charged a d are submerged in an electrolyte, say di ute sulfuric acid, contained in 45 t e jar.

The rib or 'riser 11 reviously referred to supports the active e ements at a distance, say one-half of an inch from thebase or bottom of the jar as the lower end edges of the lates 12- and 19 rest directly on the rib.

his rib is unconnected to the sides of the jar and hence it does not form an abutment vwhich will permit the formation of sediment in such a mass as to contact with the plates and cause short-circuiting. Moreover, this rib is preferably annular so that all of its surfaces presented to the sediment will be curved and will thus further serve to keep the sediment in motion inthe electrolyte.

In the ring 21, an opening 23 is provided directly below or in alinement with-the openingof a thimble 16 which may pass removably through the cover plate 15 and screw into the plate 15 as shown. A plug 17 is e5 carried kby thethimble 16 and has a vent l12 and adjacent their hub or inner edges, is

opening 18 for the escape-of gases from the jar. Plug 17 is screwthreaded to the thimble so that it may be removed to permit a syringe' or the like to pass through thimble 16 and opening 23 to withdraw electrolyte for testing purposes in addition to permitting the jar to be lled with water or electrolyte when necessary.

Located in each space between the plates an improved separator of the construction detailed in'Fig. 5. This separator is hard rubber or other suitable material which is preferably of a much higher degree of resistance to conductivity than the plates. One longitudinal edge thereof is 'be'veled from opposite sides or otherwise, made wedge or V-shaped as at 24 to snugly it between and contact with the walls of the plates 12. In the opposite longitudinal edge, a groove or slot 25 is provided to receive the inner longitudinal edges of the plates 19 of the negative element as clearly shown in Fig. 4. The separator thus not only prevents contact between the plates of opposite polarity but it-also servesv to securely hold the negative plates rigid to prevent buckling thereof.

Further the plates hold the separators fixed against any chance of displacement and the different plates and separators mutually brace leach other whereby 'the entire active structure is rigidiied and held substantially in the form of 'a cylinder.

It will be obvious by arranging the plates of the lpositive element equidistantly and directly connecting them to the postv 14 or point of delivery of the current, practically direct conductivity of the current ensues, winch accordingly reduces resistance, while wlth the negative element all of its plates .are securely held against buckling and the path of travel of the current to its post has een reduced and made more direct. As a result of this development of the principle of direct conductivity, I am enabled to obtain higher voltage and greater capacity from a cell of given active surface, or plate area, than is obtainable from cells of the present standard type.
