STORAG E BATTERY.

SPECIFICATION forming part of Letters Patent N 0. 710,870, dated October 7, 1902.

Application filed May 16,1902. Serial No.lOT,638r (N0 model- My invention relates to storage batteries,

my purpose more particularly being to produce a neat, compact, and reliable form of storage battery in which the ba ttory-plates are protected to some extent by their form.

An additional object of my invention is to produce a storage battery of comparatively great power and of a form convenient for housing in an ordinary battery-jar.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is an elevation, partly in section, showing a cell of my battery, the jar being indicated by dotted lines. Fig. 2 is a plan view of the battery-plates and their immediate connections removed from the jar, and

Fig. 3 is a sectional detail showing a slight modification of the supports used for the plates and showing the insulation upon said supports.

Mounted within the jar l is a frame coir sisting of an annularbase 2, of vulcanite, clay, or other insulating material, standards 3 4 5 6 7 8, preferably made of lead and formed or made of any other material corresponding to the material of the battery-plates, and braces 9 1O 11 12 of conducting material, these braces being so disposed as to connect the standards 3 at 5 6 7 8 in the manner indicated in Figs. 1 and 2. These braces 9 1O 11 12 serve also as conductors, connecting the plates of each kind together. The terminals are shown at 13 and ll,each terminal,ot'course, being connected with plates of a particular kind. The plates 15 16 17 1S 1.) 2O 21 are all made of the same shape and are provided with the ears 22, 23,24, 25, 26, and27. Each plate is of the form of a hollow truncated cone, the ears being flattened out for convenience in mounting the plates. Between adjacent pairs of ears are mounted annular sleeves 28 of material corresponding as nearly as practicable to that of the plates and the standards.

\Vhere the standards, sleeves, and plates are of substantially the same material, no insulation need be used between adjacent pairs of ears or upon the standards either above or below the plates. If, however, the standards are made of a material not acted upon by the battery fluid during the charging process, they are preferably insulated, as indicated in Fig. 3, by tubes 2.) and rings o0, of vulcanite. These tubes and rings should be neatly fitted upon the standards and may be temporarily cemented thereto, if desired, by means of paraflin, wax, or other suitable plastic insulator. The annularsleeves 31 (shown in Fig.3) may also be made of insulating material, if desired, the ears being fitted directly upon the metal standards 33.

The battery-plates are so arranged that the ears of one group of plates--say the negative gr0upare in alinement with each other and alternate with the groups of ears of the posi tive plates. While all of the POSlElXB plates are thus connected together and all of the negative plates are also connected together, the positive plates have no connection with the negative plates except through the medium or" the liquid in the manner customary in the ordinary use of storage batteries.

By the arrangement above described each of the battery-plates has such a form or shape thatit will resist considerable shock and pres sure and is not liable to buckle when charged and discharged rapidly by the electric current. I find that plates of this form can be distorted considerably without injury. The con formity of such a plate enables it to yield without breaking, which is not the case with plates having other arbitrary forms.

Myinventionhas no relation to the materialof which the plates are made. They may be made of lead and formed in the usual manner,'or they may be built up by pasting grids having the general shape of the finished plate. As the methods of producing battery-plates for use in storage batteries are old and well known and have no relation to my invention I do not deem ithecessary to describe them. Su'tlice it to say that a battery-plate of the shape above described can be made by any person skilled in the art of making battery-. plates of other forms.

In the drawings each conical plate is provided with three cars, so that when the positive and negative plates are connected and the ears arranged alternately six cars will be seen from the top. I do not limit myself, however, to this particular arrangement, for obviously the plates may be disposed in other relative positions.

By the invention above described I am enabled to place in a single jar a great many battery-plates of large size, so as to produce a battery of considerable power inclosed within a small space, cheaply constructed, easily handled, and having all parts readily accessible. If a particular plate be damaged, it can be readily removed. A short circuit between the plates is easilydetected, and any arbitrary desired number of plates may be used.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. -A storage battery, comprising a cylindrical cell for containing an electrolyte, a base of insulating material disposed therein,

plurality of standards of conducting material mounted upon said base, said standards being connected together in distinct groups and said groups being provided with terminals, battery-plates of frusto-conical shape and provided with ears fitted upon said stand ards, and means for spacing said plates asunder.

2. A storage battery, comprising a cylindrical vessel for containing an electrolyte, an annular base of insulating material mounted therein and arranged substantially in the form of a circle, a plurality of standards of conducting material mounted upon said base, conductors connecting said standards together in distinct groups representing positive and negative members, terminals for said groups, and battery-plates connected with said standards and spaced asunder from each other, said plates being so connected together as to form ,two distinct groups, one of said groups of plates being in contact with one of said groups of standards, and the other of said groups of plates being in contact with the-other of said groups of standards.

3. A storage battery, comprising a cell for containing an electrolyte, a frame mounted therein and provided with standards, batteryplates of hollow frusto-conical form and of,
