Die drawing of clad rod or wire

Claim 2

IN DIE DRAWING ALUMIOUS OR THE LIKE CLAD FERRROUS OR THE LIKE CORE ROD OR WIRE IN WHICH THE CLADDING IS A CONTINUOUS, COHERENT COVERING OF APPRECIABBLE THICKNESS BONDED TO SAID CORE, THE STEPS COMPRISING, IN COMBINATION,, APPLYING A TACKY SUBSTANCE TO SAID CLAD ROD OR WIRE, PULL: ING IT THROUGH A FINE POWDER DIE DRAWING SOAP LUBIRCANT COMPATIBLE WITH SAID CLADDING TO PICK UP A LUBRICANT COATING THEN PULLING IT THROUGH AT LEAST ONE PRESSURE DIE HAVING A BEARING DIAMETER SLIGHTLY LARGER THAN THE DIAMETER OF SAID CLAD ROD OR WIRE TO PREVENT COUNTER MOVEMENT OF LUBRICANT, THEN DRAWING IT THROUGH A SUCCEEDING COAXIAL REDUCTION DIE IN SEALED RELATION TO THE BACK OF SAID PRESSURE DIE AND HAVING A BEARING DIAMETER A DRAFT AMOUNT LESS THAN THE DIAMETER OF SAID CLAD ROD OR WIRE, SAID DIES DEFINING A SEALED SPACE BETWEEN SAID DIES, MAINTAINING A VERY HIGH PRESSURE OF LUBRICANT IN SAID SPACE BY MOVEMENT OF SAID CLAD ROD OR WIRE THERETHROUGH SUFFICIENT TO RESIST FORMATION OF A PROGRESSIVELY INCREASING TRANSVERSE CIRCUMFERENTIAL SHOULDER IN SAID CLADDING BY SAID REDUCTION DIE, SAID SUBJECTING SAID CLAD ROD OR WIRE TO PRESSURE CAUSED BY LUBRICANT CARRIED INTO SAID SPACE BY SAID CLAD ROD OR WIRE SUFFICIENT TO FORCE SAID CLADDING TO PASS THROUGH SAID REDUCTION DIE ALONG WITH SAID CORE FOR DRAWING OF SAID CLADDING UNIFORMLY WITH SAID CORE AND TO RECOVER THE DRAWN CLAD ROD OR WIRE DURING ITS REDUCTIION PASSAGE THROUGH SAID REDUCTION DIE WITH AN ENVELOPING THIN LAYER OF LUBRICANT CONTINUOUS ALONG AND AROUND THE SAME, SAID REDUCTION DIE HAVING ITS EXIST AT MUCH LOWER PRESSURE THAN SAID FIRST NAMED PRESSURE, WHEREBY PROPORTIONATE REDUCTION IS PROVIDED IN THE CLADDING AND CORE OF SAID CLAD ROD OR WIRE WITHOUT STRIPPING, SCORING OR UPSETTING SAID CALDDING.

Claim 3

A DIE DRAWING DEVICE FOR A CLAD ROD OR WIRE HAVING A SOFTER METAL CLADDING AND A HARDER METAL CORE, COMPRISING, IN COMBINATION, MEANS FOR LUBRICATING THE SURFACE OF SAID CLAD ROD OR WIRE COMPRISING MEANS TO AAPPLY POWDER SAOP LUBRICANT TO SAID CLAD ROD OR WIRE IN ADVANCE OF ANY PRESSURE DIE, AT LEAST A PAIR OF PRESSURE DIES EACH HAVING A CENTRAL OPENING THERETHROUGH WITH A RELATIVELY STRAIGHT-SIDED APPROACH ANGLE AND A CULINDRICAL BEARING PORTION WITH A DIAMETER SLIGHTLY LARGER THAN THAT OF SAID CLAD ROD OR WIRE TO PASS LUBRICANT THEREWITH AND PREVENT COUNTERMOVEMENT OF SAID LUBRICANT, SAID PAIR OF SUCH PRESSURE DIES BEING COAXIAL SUCCESSION WITH THE SPACE BETWEEN THEM ALSO SEALED TO PROVIDE AN OPERATIVE PPRESSURE SPACE, A COAXIAL REDUCTION DIE HAVING A SMALLER CENTRAL OPENING THERETHROUGH WITH A GENERALLY NARROW RELATIVELY STRAIGHT-SIDED APPROACH ANGLE NOT TO EXCEED IN THE NEIGHBORHOOD OF FROM ABOUT 6* TO ABOUT 12* AND A CYLINDRICAL BEARING POTION, A SEALING RING SUBSTANTIALLY IN ENGAGEMENT WITH THE REAR FACE OF THE LAST PRESSURE DIE AND THE FRONT FACE OF SAID REDUCTION DIE, SAID SEALING RING HAVING A CENTRAL OPENING TO CLAER SAID CLAD ROD OR WIRE PASSING THROUGH FROM SAID LAST PPRESSURE DIE, SAID REDUCTION DIE BEING OPERATIVE SUBSTANTIALLY TO TAKE UP THE RESISTANCE TO REDUCTION OFFERED BY SAID CLAD ROD OR WIRE TO BEING DRAWN, SAID DIES AND RING BEING COAXIAL ALIGNMENT AND THE SPACE FOLLOWING SAID REDUCTION DIE AFFORDING RELIEF TO THE DRAWN CLAD ROD AND WIRE, AND MOUNTING MEANS FOR HOLDING SAID DIES AXIALLY PRESSED TOGETHER TO SEAL THE CENTRAL OPENING SPACES BETWEEN THEM AND TO HOLD THEM RIGIDLY AGAINST LONGITUDINAL AND TRANSVERSE MOVEMENT, SAID CENTRAL OPENING SSPACE BETWEEN SAID LAST PRESSURE DIE AND SAID REDUCTION DIE BEING OPERATIVE TO PROVIDE A VERY HIGH PRESSURE CHAMBER TO FORCE SAID CLADDING METAL TO PASS THROUGH SAID REDUCTION DOE WITHOUT UPSETTING AND CONCURRENTLY WITH SAID CORE METAL WITH A CONTINUOUS LAYER OF LUBRICANT ON THE SURFACE OF SAID DRAWN CLAD ROD OR WIRE, WHEREBY A CLAD ROD OR WIRE WILL CARRY LUBRICANT INTO THE SPACE SEALED BY SAID SEALING RING TO PROVIDE A VERY HIGH PRESSURE IN SAID LAST-MENTIONED CENTRAL OPENING SPACE OPERATIVE TO PROMOTE UNIFORM DRAWING OF SAID CLADDING AND CORE IN SAID CLAD ROD OR WIRE BY SAID REDUCTION DIE.

Claim 4

A DIE DRAWING DEVICE FOR A CLAD ROD OR WIRE HAVING A SOFTER METAL CLADDING AND A HARDER METAL CORE, COMPRISING, IN COMBINATION, MEANS FOR LUBRICATING THE SURFACE OF SAID CLAD ROD OR WIRE COMPRISING MEANS TO AAPPLY POWDER SAOP LUBRICANT TO SAID CLAD ROD OR WIRE IN ADVANCE OF ANY PRESSURE DIE, AT LEAST A PAIR OF PRESSURE DIES EACH HAVING A CENTRAL OPENING THERETHROUGH WITH A RELATIVELY STRAIGHT-SIDED APPROACH ANGLE AND A CULINDRICAL BEARING PORTION WITH A DIAMETER SLIGHTLY LARGER THAN THAT OF SAID CLAD ROD OR WIRE TO PASS LUBRICANT THEREWITH AND PREVENT COUNTERMOVEMENT OF SAID LUBRICANT, SAID PAIR OF SUCH PRESSURE DIES BEING COAXIAL SUCCESSION WITH THE SPACE BETWEEN THEM ALSO SEALED TO PROVIDE AN OPERATIVE PPRESSURE SPACE, A COAXIAL REDUCTION DIE HAVING A SMALLER CENTRAL OPENING THERETHROUGH WITH A GENERALLY NARROW RELATIVELY STRAIGHT-SIDED APPROACH ANGLE NOT TO EXCEED IN THE NEIGHBORHOOD OF FROM ABOUT 6* TO ABOUT 12* AND A CYLINDRICAL BEARING POTION, A SEALING RING SUBSTANTIALLY IN ENGAGEMENT WITH THE REAR FACE OF THE LAST PRESSURE DIE AND THE FRONT FACE OF SAID REDUCTION DIE, SAID SEALING RING HAVING A CENTRAL OPENING TO CLAER SAID CLAD ROD OR WIRE PASSING THROUGH FROM SAID LAST PPRESSURE DIE, SAID REDUCTION DIE BEING OPERATIVE SUBSTANTIALLY TO TAKE UP THE RESISTANCE TO REDUCTION OFFERED BY SAID CLAD ROD OR WIRE TO BEING DRAWN, SAID DIES AND RING BEING COAXIAL ALIGNMENT AND THE SPACE FOLLOWING SAID REDUCTION DIE AFFORDING RELIEF TO THE DRAWN CLAD ROD AND WIRE, AND MOUNTING MEANS FOR HOLDING SAID DIES AXIALLY PRESSED TOGETHER TO SEAL THE CENTRAL OPENING SPACES BETWEEN THEM AND TO HOLD THEM RIGIDLY AGAINST LONGITUDINAL AND TRANSVERSE MOVEMENT, SAID CENTRAL OPENING SSPACE BETWEEN SAID LAST PRESSURE DIE AND SAID REDUCTION DIE BEING OPERATIVE TO PROVIDE A VERY HIGH PRESSURE CHAMBER TO FORCE SAID CLADDING METAL TO PASS THROUGH SAID REDUCTION DOE WITHOUT UPSETTING AND CONCURRENTLY WITH SAID CORE METAL WITH A CONTINUOUS LAYER OF LUBRICANT ON THE SURFACE OF SAID DRAWN CLAD ROD OR WIRE, WHEREBY A CLAD ROD OR WIRE WILL CARRY LUBRICANT INTO THE SPACE SEALED BY SAID SEALING RING TO PROVIDE A VERY HIGH PRESSURE IN SAID LAST-MENTIONED CENTRAL OPENING SPACE OPERATIVE TO PROMOTE UNIFORM DRAWING OF SAID CLADDING AND CORE IN SAID CLAD ROD OR WIRE BY SAID REDUCTION DIE.
