MARTIN W. ROBINSON, OF MEDFORD, MASSACHUSETTS.
ELECTRIC BATTERY.
SPECIFICATION forming part of Letters Patent No. 705,148, dated July 22, 1902.
Application filed May 11,1901. Serial No. 59,775. (No model.)
To whom it may concern:
Be it known that I, MARTIN W. ROBINSON, of Medford, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Electric Batteries, of which the following, taken in connection with the accompanyin g drawings, is a specification.
My invention relates to electric batteries; and the principal object of the same is to protide a durable or permanent non-frangible cathode oi negative element for galvanic batteries.
The carbon cathodes in common use are liable to be broken in handling if made tl1in,and if made of a thickness to be strong a free circulation of the bath liquid is impeded to some extent.
In carrying out my invention I form the cathode of a thin copper plate having a number of openings or perforations therein to permit a free circulation of the bath solution, said copper plate being coated with nickel after the openings or perforations have been formed in said plate, so that the entire surface of the cathode exposed to the bath is rendered impervious to the action of the bath solution. Such a cathode may be made comparatively thin and will not be liable to break= age in shipping or handling and may be used inconnection with the usual z'inc element in a bath composed of the usual constituents;
tional View of the cathode.
In said drawings the numeral 1 designates a non conducting cup for containing a bath solution 2,said solution being composed, preferably, of bichromate of sodium or a solution of the same and sulfuric acid in proper proportions. The cathode 3 consists of a copper plate 4., having a series of openings or perforations 5 therein to permit a free circulation of the bath solution. The copper plate 4 is coated or plated with nickel 6, said nickel being impervious to the action of the bath so lution. As shown in the drawings, a series of these nickel-plated copper plates 4 are utilized, and they are connected together by a screw 7, passing through alined apertures 8, formed in ears 9 on the upper ends of the plates. Rings or washers 10 are used to hold the plates the required distance apart, and a thumb-nut 11 fits the threaded end of the screw 7 to bind the plates together. Small butters 12, made of some impervious or nonconducting material, like vulcanite or Vulcanized fiber, are secured in suitable openings in the upper and lower portions of the plates l, said buffers extending upon opposite sides of the plates 4 to prevent contact of the zinc elements 13 with the cathodes 4. The zinc plates 13 are also secured together by a binding-screw 14, passing through a tu bular washer 15 between the plates 13.
It will be understood that any suitable number of the plates 4 and 13 may be alternately disposed in the bath and held out of contact by the butters 12 and that owing to the fact that the cathodes are comparatively thin very little space is necessary to accommodate quite a large number.
Having thus fully described my invention, what I claim is- 1. A cathode composed of a nickel'plated copper plate, having non-conducting buiters secured thereto in combination with interme diate zinc plates alternately arranged, substantially as described.
2. A cathode composed otperforated nickelplated copper plates connected together bya bindingscrew, and intermediate zinc plates, substantially as described.
3. A galvanic battery consisting of nickelplated copper cathodes and zinc anodes im= mersed in a bath composed of bichromate of sodium and sulfuric acid, substantially as described.
4. A galvanic battery consisting of perforated nickel-plated copper cathodes, secured together bya binding-screw, and zinc anodes ing the plates apart, substantially as deranged intermediate the cathodes, said elescribed. ments being immersed in a bath composed of In testimony whereof I have signed my bichromate of sodium and sulfuric acid, subname to this specification, in the presence of 15 secured together by a separate screw and ar- 5 stantially as described. two subscribing Witnesses, on this 5th day of 5.
