UNITED STATES PATENT OEEICEJ l VICTOR CHEVAL AND JOSEPH LIDEMAN, OF BRUSSELS, BELGIUM.
ELECTRIC ACCUM .U'LATOR-ELECTRODE.`
SPECIFICATION forming part of Letters Patent N o. 704,859, dated uly 15, 1902. Application led November 21,1901. Serial No. 83,108. (No modell) To @ZZ whom it may con/cern:
Be it known that we, VIcron CHEVAL and JOSEPH LINDEMAN, subjects of the King of Belgium, residing at Brussels, Belgium, have invented a new and Improved Electrode :for
Accumulator-Batteries, of which the follow# ing-isa specification;
Our invention relates to that form of accumulator-battery in Which the negative-pole electrode is a single mass of active material having cylindrical, prismatic, or other suitably-shaped openings disposed throughout its mass into which cartridge-like positive-pole electrodes may be loosely fitted, the intervening space being filled with the electrolyte.
These openings in the common negative-pole .electrode in the type of accumulator shown inour United States Patent No. 658,235 were formed of cylindrical perforated shells, the positive-pole electrodes being tted center of these shells.
The object of our present invention is to improve the construction of the positive-poleA electrode and to provide means for always keeping it central in its opening, while at the same time so placing it as to permit of its ready removal. By this means all danger of short-circuiting is overcome, and We are enf abled to use shells for the openings of the negative-pole electrode of conducting material, greatly enhancing the action of the accumnlator and reducing resistance and cost of manufacture.
In the accompanying drawings, Figure l is a sectional side elevation'of one of our improved positive-pole electrodes,'and Fig. 2 is a sectional plan of the same.
Y is the central conducting-rod, to be secured to the positive terminal of the accumulator.
into the Y X is a perforated envelop, which may be of any suitable section, but preferably rectangular, as shown, and it is preferably of insulating material. y
Z is the active material packed between the envelop and the rod.
I I are insulating radial arms secured to the envelop X, and if the envelop be also of insulating material they may be formed of one piece with it. We prefer to leave the bottom of the envelop open, as shown at I-I.
When placing this. electrode into position in a shell, the radial arms insure the proper centralization of the electrode in the shell. While the opening or shell for the electrode may be of any suitable outline or cross-see4 tion, it may conveniently be of square crosssection, as indicated by dotted lines at Gr in Fig. 2.
We claim as our invention-L l. An improved electrode for accumulatorbatteries comprising a mass of active mate rial, a perforated envelop, inclosin g the mass, and radial insulating-arms projecting from the envelop, substantially as described;
2. An'improved electrode for accumulatorbatteries, comprising a central conductlngrod, a mass of active material packed around
