Method of making a commutator strip plate

Claim 1

THE METHOD OF CONSTRUCTING COMMUTATOR STRIP PLATES WITH FACE AREAS THAT ARE RELATIVELY BROAD IN BOTH DIRECTIONS, WHICH COMPRISES WINDING AN INSULATED, ELECTRICALLY CONDUCTIVE WIRE OF A DUCTILE METAL AS A COIL PROGRESSIVELY AROUND AN ELECTRICALLY NON-CONDUCTIVE, PLATE-LIKE CORE HAVING FACE AREAS THAT ARE APPROXIMATELY SQUARE AND RELATIVELY BROAD IN BOTH DIRECTIONS, WITH THE WIRE TURNS CROSSING THE FACES OF THE CORE, TEMPORARILY CONFINING THE WIRE TURNS ON ONE FACE OF THE CORE FIRMLY AGAINST THAT CORE FACE AT INTERVALS ACROSS IT, APPLYING AN ELECTRICALLY NON-CONDUCTIVE, CURABLE POTTING MATERIAL TO SAID ONE FACE OF THE CORE AND TO THE COIL TURNS SO CONFINED THEREAGAINST, WITH THE POTTING MATERIAL BETWEEN AND SPACING SUCCESSIVE ADJACENT TURNS OF THE COIL AND BINDING THEM TO ONE ANOTHER AND TO THE CORE, AND EXTENDING PARTLY DOWN THE COIL TURNS ON THE MARGINAL EDGES OF THE CORE, REMOVING FROM THE EXPOSED POTTED FACE OF THE COIL ENOUGH WIRE INSULATION AND WIRE SURFACE TO EXPOSE A FLAT AREA OF THE METAL OF THE WIRES OVER THE POTTED FACE OF THE COIL IN A COMMON PLANE, AND SEVERING THE WIRE IN THE STRETCHES ON THE OPPOSITE, UNPOTTED FACE OF THE CORE, REMOVING THE TEMPORARY CONFINING MEANS, ADDING FURTHER POTTING MATERIAL TO FILL THE SPACES PREVIOUSLY OCCUPIED BY THE CONFINING MEANS, AND BENDING THE SEVERED ENDS OF THE WIRE STRETCHES AT ONE SIDE OF THE CORE AWAY FROM THE CORE TO PROVIDE RELATIVELY LONG, INDIVIDUAL, INSULATED LEADS FOR THE UPPER POTTED STRETCHES OF THE WIRE FOR INDIVIDUAL CONNECTION TO SUITABLE CIRCUITS.

Claim 2

THE METHOD OF CONSTRUCTING COMMUTATOR STRIP PLATES WITH FACE AREAS THAT ARE RELATIVELY BROAD IN BOTH DIRECTIONS, WHICH COMPRISES WINDING AN INSULATED, ELECTRICALLY CONDUCTIVE WIRE OF A DUCTILE METAL AS A COIL PROGRESSIVELY AROUND AN ELECTRICALLY NON-CONDUCTIVE, PLATE-LIKE CORE HAVING FACE AREAS THAT ARE APPROXIMATELY SQUARE AND RELATIVELY BROAD IN BOTH DIRECTIONS, WITH THE WIRE TURNS CROSSING THE FACES OF THE CORE, TEMPORARILY CONFINING THE WIRE TURNS ON ONE FACE OF THE CORE FIRMLY AGAINST THAT CORE FACE AT INTERVALS ACROSS IT, APPLYING AN ELECTRICALLY NON-CONDUCTIVE, CURABLE POTTING MATERIAL TO SAID ONE FACE OF THE CORE AND TO THE COIL TURNS SO CONFINED THEREAGAINST, WITH THE POTTING MATERIAL BETWEEN AND SPACING SUCCESSIVE ADJACENT TURNS OF THE COIL AND BINDING THEM TO ONE ANOTHER AND TO THE CORE, AND EXTENDING PARTLY DOWN THE COIL TURNS ON THE MARGINAL EDGES OF THE CORE, REMOVING FROM THE EXPOSED POTTED FACE OF THE COIL ENOUGH WIRE INSULATION AND WIRE SURFACE TO EXPOSE A FLAT AREA OF THE METAL OF THE WIRES OVER THE POTTED FACE OF THE COIL IN A COMMON PLANE, AND SEVERING THE WIRE IN THE STRETCHES ON THE OPPOSITE, UNPOTTED FACE OF THE CORE, REMOVING THE TEMPORARY CONFINING MEANS, ADDING FURTHER POTTING MATERIAL TO FILL THE SPACES PREVIOUSLY OCCUPIED BY THE CONFINING MEANS, AND BENDING THE SEVERED ENDS OF THE WIRE STRETCHES AT ONE SIDE OF THE CORE AWAY FROM THE CORE TO PROVIDE RELATIVELY LONG, INDIVIDUAL, INSULATED LEADS FOR THE UPPER POTTED STRETCHES OF THE WIRE FOR INDIVIDUAL CONNECTION TO SUITABLE CIRCUITS.
