  • Patent number: 5422199
    Abstract: A wet, multicell, lead-acid electric storage battery is provided for. The battery comprises a container, a cover, one or more partition walls dividing the space within the container and cover into two or more cell cavities. The cover defines generally cylindrically shaped process holes associated with each cell cavity. The battery further comprises a venting system. The venting system comprises a manifold defined by the cover, the manifold having at least one opening in each process hole and at least one opening in the cover. The manifold is adapted to provide gaseous communication between the process holes and the ambient. The venting systems also comprises a venting plug associated with each process hole and adapted for insertion therein. The venting plugs have a generally cylindrical side wall, a closed upper end, an open lower end, and a central cavity. A vent aperture is located in the side wall of the venting plug and is in gaseous communication with the manifold and the venting plug central cavity.

  • Patent number: 4859547
    Abstract: A battery terminal post of the type for use in electrolytic devices contained by resilient electrolyte-resistant walls, wherein an opening in the electrolytic device wall is radially enlarged to form a bushing, into which is inserted a second T-shaped lead alloy bushing, into which in turn there is inserted a complementary third bushing of pure lead, which three bushings are then forced into intimate sealing contact by being radially expanded by the action of a punch and die in a swaging operation.
