Apparatus for welding contacts on conductive parts

Claim 1

AN APPARATUS FOR WELDING CONTACTS ON SUCCESSIVELY ADVANCED CONDUCTIVE PARTS WHICH ARE JOINED END TO END IN A GENERALLY FLAT METAL STRIP OF INDETERMINATE LENGTH, WHICH COMPRISES, A FIRST ELECTRODE HAVING A RECESS THEREIN OVER WHICH THE PARTS ARE ADVANCED, A GUIDE FOR A CONDUCTIVE RIBBON FROM WHICH THE CONTACTS ARE TO BE CUT, A CUTTER INTERPOSED BETWEEN THE GUIDE AND THE FIRST ELECTRODE AND HAVING AN APERTURE THEREIN TO RECEIVE A LENGTH OF THE RIBBON, MEANS TO ADVANCE THE RIBBON LONGITUDINALLY IN THE GUIDE TRANSVERSE TO THE ADVANCE OF SAID METAL STRIP OF PARTS, TO FEED MEASURED LENGTHS THEREOF SUCCESSIVELY INTO THE APERTURE OF THE CUTTER, MEANS FOR MOVING THE CUTTER RELATIVE TO THE GUIDE TO CUT CONTACTS OF SAID SUCCESSIVELY MEASURED LENGTHS THEREFROM, AND FOR MOVING SAID CUTTER TO ALIGN THE APERTURE THEREIN WITH THE RECESS IN THE FIRST ELECTRODE, WHEREUPON SAID CUT CONTACTS ARE PUSHED, BY THE ADVANCE OF THE NEXT SUCCESSIVE ADVANCED UNCUT RIBBON, INTO THE RECESS IN SAID FIRST ELECTRODE, A SECOND MOVABLE ELECTRODE, MEANS RENDERED EFFECTIVE UPON PUSHING SAID CONTACT INTO SAID RECESS FOR MOVING SAID SECOND ELECTRODE TO PRESS THE PART INTO ENGAGEMENT WITH THE CONTACT IN THE RECESS TO FORM A POCKET THEREIN FOR THE CONTACT, MEANS FOR APPLYING WELDING ENERGY TO SAID ELECTRODES TO WELD THE CONTACTS SUCCESSIVELY TO THE PARTS, AND MEANS RESPONSIVE TO THE WELDING OF THE CONTACTS TO THE PARTS FOR ADVANCING SAID INDETERMINATE LENGTH STRIP OF PARTS TO POSITION EACH SUCCESSIVELY ADVANCED PART INTO ALIGNMENT WITH SAID SECOND ELECTRODE.

Claim 2

AN APPARATUS FOR WELDING CONTACTS ON SUCCESSIVELY ADVANCED CONDUCTIVE PARTS WHICH ARE JOINED END TO END IN A GENERALLY FLAT METAL STRIP OF INDETERMINATE LENGTH, WHICH COMPRISES, A FIRST ELECTRODE HAVING A RECESS THEREIN OVER WHICH THE PARTS ARE ADVANCED, A GUIDE FOR A CONDUCTIVE RIBBON FROM WHICH THE CONTACTS ARE TO BE CUT, A CUTTER INTERPOSED BETWEEN THE GUIDE AND THE FIRST ELECTRODE AND HAVING AN APERTURE THEREIN TO RECEIVE A LENGTH OF THE RIBBON, MEANS TO ADVANCE THE RIBBON LONGITUDINALLY IN THE GUIDE TRANSVERSE TO THE ADVANCE OF SAID METAL STRIP OF PARTS, TO FEED MEASURED LENGTHS THEREOF SUCCESSIVELY INTO THE APERTURE OF THE CUTTER, MEANS FOR MOVING THE CUTTER RELATIVE TO THE GUIDE TO CUT CONTACTS OF SAID SUCCESSIVELY MEASURED LENGTHS THEREFROM, AND FOR MOVING SAID CUTTER TO ALIGN THE APERTURE THEREIN WITH THE RECESS IN THE FIRST ELECTRODE, WHEREUPON SAID CUT CONTACTS ARE PUSHED, BY THE ADVANCE OF THE NEXT SUCCESSIVE ADVANCED UNCUT RIBBON, INTO THE RECESS IN SAID FIRST ELECTRODE, A SECOND MOVABLE ELECTRODE, MEANS RENDERED EFFECTIVE UPON PUSHING SAID CONTACT INTO SAID RECESS FOR MOVING SAID SECOND ELECTRODE TO PRESS THE PART INTO ENGAGEMENT WITH THE CONTACT IN THE RECESS TO FORM A POCKET THEREIN FOR THE CONTACT, MEANS FOR APPLYING WELDING ENERGY TO SAID ELECTRODES TO WELD THE CONTACTS SUCCESSIVELY TO THE PARTS, AND MEANS RESPONSIVE TO THE WELDING OF THE CONTACTS TO THE PARTS FOR ADVANCING SAID INDETERMINATE LENGTH STRIP OF PARTS TO POSITION EACH SUCCESSIVELY ADVANCED PART INTO ALIGNMENT WITH SAID SECOND ELECTRODE.
