Method and apparatus for casting straps onto storage battery plates
First Claim
1. A method for casting elements onto storage battery plates comprising;
- providing a source of molten lead;
receiving a first mold block having five mold cavities linearly aligned in an upper face thereof in a first molding station, whereby at least two preselected cavities of the five mold cavities are filled with lead;
translating the mold block to align each of the at least two preselected cavities with the source of molten lead; and
translating the mold block toward a battery plate group to dip lugs of the group into the at least two preselected cavities.

Abstract
A method and apparatus for preparing connecting straps and end terminals for lead batteries by filling selected cavities of the mold is disclosed. The mold has cavities for casting connecting straps and an end terminal. Molten lead is filled up to an amount of lead sufficient to fill the preselected cavities of the mold. The content of the mold is brought together with inverted plate lugs of grouped battery plates to fuse the plate lugs together with the content of the mold prior to solidification. The method and apparatus includes a first mold block having at least three mold cavities in an upper face thereof, whereby at least two preselected cavities of the at least three mold cavities are translationally aligned to be filled with lead.

selecting a first two contiguous strap cavities including said second strap cavity;
filling said first two contiguous strap cavities with molten lead;
joining a first single cell to said first two contiguous strap cavities to form a fifth molded cell element;
selecting a second two contiguous strap cavities including said fourth strap cavity;
filling said second two contiguous strap cavities with molten lead; and
joining a second single cell to said second two contiguous cavities to form a sixth molded cell element.

11. The method of claim 7 wherein the cell elements produced are disposed in a battery case wherein each extension tab is aligned with holes in cell partition walls within the battery case, each extension tab aligned with another extension tab in a contiguous cell for electrically joining tabs extending in contiguous cells together to provide a series connection between the cells of the battery.
