Method and apparatus for casting straps and terminals on lugs of storage battery plates
First Claim
1. A method of casting straps and terminals on lugs of storage battery pates comprising the steps of:
- a) gathering a group of battery plates and separators comprising a battery cell group,b) placing the group of plates and separators partially within a non-metallic battery case with the lugs of the plates extending out of the case,c) at a loading station placing the battery case partially in a carrier,d) placing a heat shield about the edges of the case adjacent the plate lugs,e) rotating the carrier to orient the lugs in a downward direction,f) lowering the carrier toward a casting mold to cause the lugs to be immersed in molten lead, andg) raising the carrier following setting of the lead.

Abstract
A system for casting straps and terminals on lugs of storage batteries includes a loading station including means for receiving at least one non-metallic battery case having a plurality of plates and separators partially inserted in the case with lugs extending out of the case. Clamping structure holds the battery case in position and includes metallic structure for overlying edges of the case to insulate the edges of the battery case from heat. Means rotates the receiving means to position the lugs in a downward substantially vertical direction. Included is a casting mold for receiving molten lead. Transportation means moves the receiving means over the casting molds and lower the lugs into the casting mold. Following the setting of the lead, the receiving means is transported to an un-loading station where the battery case is removed from the receiving means. The casting mold includes a vent for letting air from the mold as molten lead is added to the mold. The vent terminates in an exit port having an effective diameter of no more than 0.5 thousand inch.

5. A system for casting straps and terminals onto lugs of storage battery plates comprising;
-
a) a loading station including means for receiving at least one non-metallic battery case having a plurality of plates and separators partially inserted in the case with lugs extending out of the case, b) said receiving means including means for clamping and holding the case in position and including metallic structure for overlying edges of the case and thus insulate the edges from heat, c) means for rotating said receiving means to position the lugs in a downward direction, d) a casting mold for receiving molten lead, e) means for transporting said receiving means to said casting mold form casting straps and terminals onto the lugs, f) means for lowering said receiving means to insert the lugs into the molten lead, g) means for raising said receiving means to withdraw the lugs from said mold after the lead has set, and h) means for transporting said receiving means to an unloading station where the case is removed from said receiving means. - View Dependent Claims (6, 7, 8, 11, 12)

9. A system for casting straps and terminals onto lugs of storage battery plates comprising;
-
a) a loading station including receiving means having a plurality of chambers for receiving non-metallic battery cases each containing a plurality of plates and separators partially inserted into each case with plate lugs extending out of the cases, b) means for closing said chambers upon the cases to clamp the cases and hold them in position, each chamber including metallic structure for overlying edges of the cases when said chambers are in a closed position to insulate the edges of the cases from heat, c) means for rotating said receiving means to position the hugs in a downward direction, d) a casting mold structure for receiving molten lead and having a plurality of casting molds equal to the number of battery cases, e) means for transporting said receiving means and battery cases to a position over said casting mold structure, f) means for lowering said receiving means to insert the lugs into the molten lead contained in said casting molds, g) means for raising said receiving means to withdraw the lugs from said molds after the lead has set, and h) means for transporting said receiving means to an unloading station where the cases are to be removed from said chambers. - View Dependent Claims (10)
