T all whom it may concern.-

Be it known that I, CHQIMSONOVITZ PROS- PER ELIEsON, a citizen of the Republic of France, residing at London, England, have 5 invented new and usefullmprovementsin Electrical Accumulators or Storage-Batteries, (for which I have obtained patents in the following countries, viz: Great Britain by Letters Patent N0. 9,522, dated August lO, 1885; in Germany by Letters Patent No. 35,194, dated October 17, 1885; in .France by Letters Patent No. 175,193, dated April 1, 1886; in Belgium by Letters Patent No. 73,084, dated May p 12, 1886; in Luxemburg by- Letters Patent No. 685, dated May 16, 1886; in 'the Cape of Good Hope by Letters Patent No. 6/420, Register No. 356, dated J une 24, 1886; in Italy by Letters Patent XX, No. 19,913, XL, No. 122, dated June 30, 1886; in Victoria by Lette'rs Patent No. 4,617, dated July 9, 1886; in South Australia by Letters Patent No. 702, dated July 26, 1886; in New Zealand by Letters Patent No. 1,937, dated July 29, 1886; in Spain by Letters Patent No. dated September 1, 1886;' in New South Wales by Letters of Registration No. 1,919, dated September 6, 1886; in AustriaHungary by Letters Patent N o. 18,560 and No. 47,634, dated September 24, 1886, and in India by Letters Patent N0. 1,557, Register No. 112 of 1886, dated December 6,1886,) of which the following is a specification.

The object of my invention is to improve the construction of electrical accumulators or so-called secondary batteries by providing a very large area of acting surface without pasting or otherwise attaching salts of lead to the plates before formation,

In order to enable myinvention to be fully understood, I will describe the same by reference to the accompanying drawings, in which- Figures 1 and 2.represent front and side views, respectively, of an electrical acc-umulator or storage-battery made according to my invention, the box or containing-Vessel being shown in section.

In constructing an accumulator according to my invention I use a frame, a, made ordi narily of lead, which is divided or formedinto divisions or compartments b, of any suitable shape, the divisions or compartments being shown square in the drawings; but it Will be obvious that they may be of any other suitable shape. I take a strip of' thin sheet-lead. Upon the said strip I place another strip of sheetasbestus or other suitable insulating and acid-proof material. I roll up the strips so as to form a compact spiral, c, cylindrical in shape. Iinsert one of these spirals c into each compartment or division b in the before-mentioned frame a. A series of such frames are arranged in a suitable containing-Vessel, d, as shown in Fig. 2, and I pass a current through them, forming them in the usual way-that is to say, oxidizing one plate to form -lterminal and hydrogenizing the other to form terminal. l

Among the advantages of my improved electrieal accumulators may be mentioned, first, that there are no oxides of lead required to be placed thei-ein, which in a crude form are liable to crumble, and by falling between the plates short-circuit the battery; second, that the spiral as constructed according to my invention affords a very large acting surface for electrical storage, whereby such storage may be carried out without adding the unnecessary weight, which constitutes a serious objection against accumulators when used for electrical traction or other kindred applications where the minimum weight against time-storage is a desideratum; third,that suchacell constructed according to my invention increases in capacity during its useful life, which is only shortened by the disintegration ofthe leaden frame.

Tn the drawings I have shown the spirals a as being of greater length than the thickness of the frames a; but such is not necessary, as

2. The combination of a containing-vessel,

Having now particularly described and asa series of frames inclosed Within said Vessel, certained the natn re of my said invention and and the spirals c, contained within said frame, in what manner the same is to be performed, I substantially as hcreinbefore described. declare that what I claim is-- 1. A11 electrical accumulator consisting of a frame of lead or other suitable material, coni tainingspirals of sheet-lead, whose surfaces are separated by suitable insulating` and acid-proof I material, substantially as hereinbefore described.

the ends of the spirals may be fiush therewith.
