Abstract
Abstract Battery plates are mounted and aligned in jigs, dipped into a solder bath and then held in a mold while a lead strap or connecting bracket is cast therein and fused to the plates in one operation. When the lead solidifies the battery plates are firmly attached thereto. One variation involves dipping the plates in a flux solution before they are dipped in the solder bath. Other variations include subjecting the solder bath or the flux solution to ultrasonic vibrations to enhance the tinning or washing action.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
97 words
A PROCESS FOR CASTING BATTERY PLATES ONTO A CONNECTION STRAP COMPRISING THE SUCCESSIVE STEPS OF: HOLDING AND ALIGING A STACK OFBATERY PLATES AND SEPARATORS, DIPPING THE CONNECTING LUGS OF SAID PLATES IN SAID STACK INTO A FLUX SOLUTION. DIPPING THE CONNECTING LUGS OF SAID PLATE IN SAID STACK INTO A SOLDER BATH, CASTING A CONNECTING STRAP WITH MOLTEN LEAD, IMMEDIATELY IMMERSING THE CONNECTING LUGS OF SAID PLATES INTO SAID MOLTEN LEAD AFTER LEAVING SAID SOLDER BATH, AND HOLDING THE STACK IN THE IMMERSED POSITION UNTIL THE LUGS OF SAID PLATES ARE CAST ONTO THE SOLIDIFIED CONNECTING STRAP

A PROCESS FOR CASTING BATTERY PLATES ONTO A CONNECTION STRAP COMPRISING THE SUCCESSIVE STEPS OF: HOLDING AND ALIGING A STACK OFBATERY PLATES AND SEPARATORS, DIPPING THE CONNECTING LUGS OF SAID PLATES IN SAID STACK INTO A FLUX SOLUTION. DIPPING THE CONNECTING LUGS OF SAID PLATE IN SAID STACK INTO A SOLDER BATH, CASTING A CONNECTING STRAP WITH MOLTEN LEAD, IMMEDIATELY IMMERSING THE CONNECTING LUGS OF SAID PLATES INTO SAID MOLTEN LEAD AFTER LEAVING SAID SOLDER BATH, AND HOLDING THE STACK IN THE IMMERSED POSITION UNTIL THE LUGS OF SAID PLATES ARE CAST ONTO THE SOLIDIFIED CONNECTING STRAP
Claim 3
Dependent Claim
27 words
The process of claim 1 including the additional step of vibrating the flux solution during the flux dipping step so as to further help wash the plates.
Claim 4
Independent Claim
104 words
A method of casting battery plates onto a connecting strap comprising the steps of: holding and aligning the battery plates with a temporary mounting means; dipping the connecting portions of said plates into a flux solution; dipping the connecting portions of the aligned plates into a molten lead alloy bath; removing the connecting portions of the plates from the lead alloy bath and immediately positioning said connecting portions of the plates in the surface of the connecting strap while the strap is being cast and is still molten; and holding said plates in position until the plates are cast onto the cooled solidified strap.
Claim 5
Independent Claim
104 words
A method of casting battery plates onto a connecting strap comprising the steps of: holding and aligning the battery plates with a temporary mounting means; dipping the connecting portions of said plates into a flux solution; dipping the connecting portions of the aligned plates into a molten lead alloy bath; removing the connecting portions of the plates from the lead alloy bath and immediately positioning said connecting portions of the plates in the surface of the connecting strap while the strap is being cast and is still molten; and holding said plates in position until the plates are cast onto the cooled solidified strap.
Claim 6
Dependent Claim
32 words
The method of claim 3 including the step of introducing ultrasonic vibrations into the molten alloy bath during immersion of the plates so as to further help wash and coat the plates.
Claim 7
Dependent Claim
29 words
The method of claim 4 including the step of introducing ultrasonic vibrations into the flux solution during immersion of the plates so as to further help wash the plates.
