ISAIAH L. ROBERTS, OF BROOKLYN, ASSIGNOR TO THE ROBERTS-BREVOORT ELECTRIC COMPANY, (LIMITED,) OF NEWV YORK, N. Y.
DIAPHRAGM FOR GALVANIC BATTERIES.
SPECIFICATION forming part of Letters Patent No. 414,081, dated October 29, 1889.
Application filed May 5, 1887. Serial No. 237,259. (No model.)
To all whom it may concern: Such a cup maybe of any well-known form- Be it known that I, ISAIAH L. ROBERTS, a such, for instance, as that illustrated in the resident of. the city of Brooklyn, county of accompanying drawings, in which Kings, and State of New York, and a citizen of Figure 1 is a perspective view of the cup or 55 5 the United States, have made a new and useseparating-diaphragm A, and Fig. 2 is a verful Improvement in Electric Batteries, of tical section of a two-cell battery B, containwhich the following is such a full, clear, and ing the cup or separating-diaphragrn A, but exact description as will enable others skilled without the electrodes. in the art to piactice the same. Itis known in practical chemistry that cer 6o 10 In conjunction with Henry L.

These substances cause the silican be produced.

When these mineral gelatinous substances, or I use this is accomplished, the separating-partition them alone, employing as a support or holder is formed by the walls of theporous cup havpreferably a porous cup or a sheet of wool or ing its pores closed with the mineral gelatifur felt, so that the pores of the separatingnous mass.

Thus a porous position. It is evident that this can be done 10c cup of baked earthenware or a cup of felt with all of the various substances which form stretched over a frame I find convenient. whatI call mineral gelatinous masses. Now,
my invention includes all such substances, and, though I prefer to use the silicates of soda or potash and I prefer to use a porous holder in the pores of which the gelatinous material is formed, I do not limit myself to forming the gelatinous mass in the pores of the supporting or holding substance, for it may be introduced between or into such substances in various .ways which will be evident to the skilled chemist.
I do not Wish to limit myself to any particular form or construction of holder or support, or to any particular mineral substance I which can be gelatinized, or to any particular method of gelatinizing the substance. The gelatinous material may be formed between supports into acup form without having any holder or support when in the battery, and these cups can then be used. Sheets of the material may also be so made; but I prefer to use a holder or support.
I do not herein claim a separating-partition foran electric battery consisting of earthenware having its pores closed with gelatinous material, or such a partition consisting of i earthenware having its pores closed with ge- 2.
