Apparatus for connecting a battery plate to a metal strap or post

Abstract

This invention relates to apparatus for connecting a battery plate to a metal strap or post or to moulds therefor. In contrast to existing arrangements lead is fed to the feed passage 17 via an opening 20 which is positioned immediate the ends of the aligned cavities in the set 14 of the mould. This arrangement enables the cavities to be fed with lead at approximately the same time and hence the dip of the lugs into the cavities can be optimised without any significant difficulties. In itself this substantially increases productivity. It has also been found that up to three batteries can be cast simultaneously, particularly if bypasses 16 c are used for fine tuning the lead supply.

1 . A mould for apparatus for connecting a battery plate to a metal strap or post, the mould including an aligned set of post or strap cavities, a molten metal feed duct for feeding all the cavities in the set and extending adjacent thereto, a weir between the feed duct and the cavities, a feed passage extending below the feed duct for supplying molten lead to the duct and for allowing drain back of the lead characterised in that there is at lest one body disposed in the feed duct so as to reduce the volume of the part of the feed duct, which lies between the lowest and highest level in the duct for lead in a cycle.
