POROUS DIAPHRAGM FOR BATTERIES.
SPECIFICATION forming at-t 6f Letters i atnt 1\To. 688,07"); dated December 3, 1961. Application filed May17, i'eoi. semi No. 60,703. on) modlJ To all who???) it may c mera.-
Be it knownthat I, GEORGE T. EYANSON, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain 5 Improvementsin Porous DiaphragmsforBatteries, of which the following is a specification.
My invention relates to certain improvements in porous partitions or diaphragms for X0 batteries, having for its object the provision of a device of the character described which while being relatively light shall at the same time be structurally strong and durable. This object I attain as hereinafter set forth,
reference being had to the accompanying drawings, in which- Figure l is a side view of a porous plate made according to my invention,showing four porous sections held in a suitable frame. Fig.
2 is an enlarged sectional view on the line 2 2,
Fig. 1. Fig. 3 is a perspective view of one of the porous sections of which the plate shown in Fig. l is composed. Fig. lis a perspective view of a porous vessel or cup fora battery, the same having its front and rear sides made of plates similar to that shown in Fig. 1. Fig. 5 is an enlarged sectional view on line 5 5, Fig. 1.
In the drawings, A A are plate-sections of a porous electrically non-conducting material-as for instance, unglazed porcelain or other earthenware. These sections have grooves (1 Ct running across their flat surface,
preferably only on one side, as shown in the figures, and wherever these intersect a hole ct is made through the plate, there being two of these points in the section illustrated. The
edges of the plate-section are also made with a groove a and around the whole is cast a frame B. This frame is preferably made of lead and extends into the groove a It also enters the grooves a ct and passes through the holes a, which may, if desired, be made countersunk on the side opposite to the grooves, as shown in Fig. 2. In making up a complete plate the edges of several platesections are burned together, forming a partition or diaphragm of the appearance illustrated in Fig. 1. Two of these composite diaphragrns may be joined by end pieces I) Z) and 56 a back piece b, the same being of lead and united to the frames 13 B by burning. Within the cup or vessel formed one of the zinc elements of a battery is placed, being held out of contact with the lead frame and end plates by means of suitable insulators.
It will be understood that my invention may be used not only to form the sides of a porous cup, but also as a simple dividingpartition to separate a battery-cell into com- 60 partments. For this purpose thesize of the porous-plate section A may be varied, there being a greater or less number of the'grooves a a, according to the size of the said section and varying numbers of plate-sections to the completed diaphragm.
I claim as my invention-- 1. The combination of a plate of electrically non-conducting porous material, having grooves runningacrossitssurface andaframe 7o surrounding said plate and extending into said grooves, substantially as described.
2. The combination of an electrically nonconducting porous plate, grooves in the edges and other grooves extending across the fiat surface thereof, holes through the plate and a frame extending around said plate, entering the grooves thereof and extending into said holes, substantially as described.
3. A diaphragm for a battery, the same consisting of a number of porous, electrically non-conducting plates, grooves in the edges and across the flat faces of said plates, holes through the plates at points of intersection of the grooves, and a metallic frame surround- 8 ing the plates, the same having parts extending into the grooves and entering the holes, substantially as described.
4. A porous vessel for batteries, the same consisting of solid ends and a bottom, with go sides, the said sides consisting of plates of porous, electrically non-conducting material, having grooves in their flat surfaces, the said plates being held together by a framework extending into the grooves and joined to the said ends and bottom, substantially as described.
5. As a new article of manufacture, a porous vessel for batteries, the same consisting of a In testimony whereof I have signed my' box-like structure having in its sides grooved name to this specification in the presence of plates of porous electrically non-conducting two subscribing witnesses.
