SPECIFICATION forming part of Letters Patent No. 516,653, dated March 20, 1894.

Application led May 23.1893.

To ZZ whom it may concern.:

Be it known that I, LORENZO FLOOD LARY, a citizen of the United States, residing at Pottersburg, in the county of Union and State of Ohio, haveinvented certain new and useful Improvements in Gravity-Batteries; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in that class of galvanic batteries, known as gravity batteries, and it has for its general object to provide a battery embodying such a construction that a space is afforded at the bottom of the cell for the sulphate of zinc so as to prevent the loss of copper by deposit on such particles and keep the copper solutionl free from foreign matter.

Another object of the invention is to provide a copper electrode adapted to serve as a receptacle for theblue vitriol, and embodying such a construction that it may be spread out at when removed from the cell so as to facilitate the removal of copper formations.

Other objects and advantages of the invention will appear from the following description and claims when taken in connection with the accompanying drawings, in which- Figure l, is a vertical, diametrical section of a battery embodying my invention. Fig. 2, is a plan view of the copper electrode in the shape it assumes when placed in the cell, and Fig. 3, is a view illustrating the copper electrode as spread out so as to facilitate the removal of copper formations.

Referring by letter to said drawings:-A, indicates a cell which may be of any approved form and construction, and B, indicates the zine or negative electrode which may be of the well known crows foot, or other pattern. This electrode is preferably provided with `a hook a, as shown, whereby it is supported in the cell, and it is connected to the circuit wire b, through the medium o'fthe binding post c, or in any other approved manner.

C, indicates the copper or positive electrode of the battery which is designed to rest upon the bottom of the cell and serve as a receptacle for the blue vitriol or equivalent exciting substance, indicated by D. In forming this Serial No. 475389. (No model.)

copper electrode C, I take a sheet of copper and cut it so as to' form a generally elliptical ligure, that is one having one of its longitudinal edges and its ends rounded as shown at d, and e, and havinga segment removed from its other longitudinal edge. I then provide the sheet with a large aperture g, and aseries of comparatively small apertures h, after which I slitit as illustrated to form the tongue supportf.` I then bend the sheet as shown in Fig. 2, so as to form the inverted cone (see Fig. 3,) having the aperture g, at its lower end, and I also bend the tongue f, outwardly, as illustrated in the said figure, so that it serves to support the'electrode above the bottom of the cell.

In addition to the tongue supportf, I provide the cone shaped electrode with a prop or support as t; and, if necessary, the said electrode may be further supported-by bending the circuit wirej, over the upper edge of the cell.

In the practice of my invention, the cone shaped electrode, charged With a sufficient quantity of blue vitriol, or other excitant, is placed in the cell as shown in Fig. l, so as to form a chamber or space at the bottom of the same. The zinc or negative electrode is then placed in position, after which the liquid is added.

In the practice of my invention, I prefer to employ a cone shaped copper electrode formed in the manner herein illustrated and described, as the same is advantageous, but I do not desire to be understood as confining myself to an electrode formed in such manner, nor do I want to be confined to an electrode of cone shape as any approvedshape of electrode may be employed that will serve at once as a receptacle for the excitant and to form a chamber at the bottom of the cell.

Having described my invention, what I claim isl. The electrode O, formed by asheet of material bent or furled into cone shape, and having an aperture in its bottom; said electrode being adapted to serve as a receptacle for an excitant and being also adapted to be unfurled and flattened out so as to facilitate the removal of chemical formations, substantially as specified.

2. The combination with a cell and an zinc IOO or negative eiectroe arranged therein; of a Intestimony whereof I afx my signature in copper or positive electrode formed by bendpresence of two witnesses. ing a sheet of copper into cone shape; said electrode having an aperture at its bottom Y LORENZO FLOOD LARY 5 and also having the integral support'J f, and Witnesses:

the support substantially as and for the ORLANDO BURL EATON purpose set forth. LESTER WARE CLINE.
