Apparatus for treating filament yarn

Claim 1

AN APPARATUS FOR TREATING A SYNTHETIC CONTINUOUS FILAMENT YARN MADE FROM A NYLON POLYMER WHEREBY POTENTIAL CRIMPINESS IS IMPARTED THERETO COMPRISING, IN COMBINATION, ROTABLY MOUNTED THREAD ADVANCING ROLLS ADAPTED TO SUPPLY A MOLECULARLY ORIENTABLE NYLON CONTINUOUS FILAMENT YARN FROM A SOURCE AT A PREDETERMINEDF FIRST RATE, A PAIR OF TOOTHED WHEEL MEMBERS HAVING HORIZONTALLY DISPOSED PARALLEL AXES, EACH MEMBER BEING FIXEDLY MOUNTED ON SEPARATE SHAFTS JOURNALED IN A SUPPORTING FRAME, THE TEETH OF SAID WHEEL MEMBERS BEING UNIFORMLY CIRCUMFERENTIALLY ARRANGED TO BE ENGAGEABLE THEREBETWEEN IN CLOSELY SPACED ADJUSTMENT AND EXTENDING IN PARALLEL RELATION ALONG THE LENGTHS OF SAID MEMBERS, SAID MEMBERS BEING ADAPTED TO RECEIVE SAID YARN AND TO ADVANCE SAME AT A PREDETERMINED INCREASED RATE AS COMPARED TO THE SUPPLY RATE OF SAID YARN, WHEREBY THE YARN NORMALLY ADVANCING BETWEEN SAID THREAD ADVANCING ROLLS AND SAID WHEEL MEMBERS IS ATTENUTATED A PREDETERMINED EXTENT THEREBY TO INCREASE THE MOLECULAR ORIENTATION THEREOF MEANS TO DRIVE SAID PAIR OF WHEEL MEMBERS IN UNISION, A NON-ROTATABLE STRETCH PIN MOUNTED AT ONE OF ITS ENDS IN THE FILAMENT PATH BETWEEN SAID THREAD ADVANCING ROLLS AND SAID WHEEL MEMBERS AND HAVING A SMOOTH WEAR RESISTANT FILAMENT CONTACT SURFACE AROUND WHICH SAID YARN IS WRAPPED IN OPERATION AT LEAST ONCE AND DESCRIBES A HELICAL PATH EXTENDING LONGITUDINALLY FORWARD WITH RESPECT TO THE MOUNTED END OF SAID PIN, ELECTRICALLY ENERGIZABLE RESISTANT HEATER INSIDE SAID PIN TO HEAT SAME INTERNALLY, THEREBY TO LOCALIZE THE ATTENTUATION OF SAID YARN AND TO IMPART HEAT TO SADI YARN IN ITS TRAVEL BETWEEN SAID THREAD ADVANCING ROLLS AND SAID WHEEL MEMBERS, A SEPARATOR ROLL MOUNTED ADJACENT SAID WHEEL MEMBERS IN SPACED RELATIONSHIP THEREWITH AND POSITIONED AT A SLIGHT ANGLE WITH RESPECTT TO THE AXES OF SAID WHEEL MEMBERS IN ORDER THAT THE YARN NORMALLY PROGRESSING AROUND ONE WHEEL MEMBER AND SAID SEPARATOR ROLL WILL DESCRIBE ENERALLY A HELIX, THE CONVOLUTIONS OF WHICH ARE SPACED APART, WHEREBY THE YARN ADVANCES ALONG THE ONE WHEEL MEMBER FROM THE INBOARD END THEREOF TO THE OUTBOARD END THEREOF DURING ROTATION OF SAID WHEEL MEMBERS, SAID PAIR OF WHEEL MEMBERS BEING POSITIONED ADJACENT SAID STRETCH PIN IN SPACED RELATION THEREWITH SO THAT SAID WHEEL MEMBERS ATE ADAPTED TO RECEIVE THE HEATED YARN FORTHWITH FROM SAID STRETCH PIN, AND MEANS FOR TAKING UP SAID YARN IN AN ORDERLY MANNER AFTER SAID YARN HAS PASSED BETWEEN SAID PAIR OF WHEEL MEMBERS AND AROUND SAID SEPARATOR ROLL A PLURALITY OF TIMES.

Claim 2

AN APPARATUS FOR TREATING A SYNTHETIC CONTINUOUS FILAMENT YARN MADE FROM A NYLON POLYMER WHEREBY POTENTIAL CRIMPINESS IS IMPARTED THERETO COMPRISING, IN COMBINATION, ROTABLY MOUNTED THREAD ADVANCING ROLLS ADAPTED TO SUPPLY A MOLECULARLY ORIENTABLE NYLON CONTINUOUS FILAMENT YARN FROM A SOURCE AT A PREDETERMINEDF FIRST RATE, A PAIR OF TOOTHED WHEEL MEMBERS HAVING HORIZONTALLY DISPOSED PARALLEL AXES, EACH MEMBER BEING FIXEDLY MOUNTED ON SEPARATE SHAFTS JOURNALED IN A SUPPORTING FRAME, THE TEETH OF SAID WHEEL MEMBERS BEING UNIFORMLY CIRCUMFERENTIALLY ARRANGED TO BE ENGAGEABLE THEREBETWEEN IN CLOSELY SPACED ADJUSTMENT AND EXTENDING IN PARALLEL RELATION ALONG THE LENGTHS OF SAID MEMBERS, SAID MEMBERS BEING ADAPTED TO RECEIVE SAID YARN AND TO ADVANCE SAME AT A PREDETERMINED INCREASED RATE AS COMPARED TO THE SUPPLY RATE OF SAID YARN, WHEREBY THE YARN NORMALLY ADVANCING BETWEEN SAID THREAD ADVANCING ROLLS AND SAID WHEEL MEMBERS IS ATTENUTATED A PREDETERMINED EXTENT THEREBY TO INCREASE THE MOLECULAR ORIENTATION THEREOF MEANS TO DRIVE SAID PAIR OF WHEEL MEMBERS IN UNISION, A NON-ROTATABLE STRETCH PIN MOUNTED AT ONE OF ITS ENDS IN THE FILAMENT PATH BETWEEN SAID THREAD ADVANCING ROLLS AND SAID WHEEL MEMBERS AND HAVING A SMOOTH WEAR RESISTANT FILAMENT CONTACT SURFACE AROUND WHICH SAID YARN IS WRAPPED IN OPERATION AT LEAST ONCE AND DESCRIBES A HELICAL PATH EXTENDING LONGITUDINALLY FORWARD WITH RESPECT TO THE MOUNTED END OF SAID PIN, ELECTRICALLY ENERGIZABLE RESISTANT HEATER INSIDE SAID PIN TO HEAT SAME INTERNALLY, THEREBY TO LOCALIZE THE ATTENTUATION OF SAID YARN AND TO IMPART HEAT TO SADI YARN IN ITS TRAVEL BETWEEN SAID THREAD ADVANCING ROLLS AND SAID WHEEL MEMBERS, A SEPARATOR ROLL MOUNTED ADJACENT SAID WHEEL MEMBERS IN SPACED RELATIONSHIP THEREWITH AND POSITIONED AT A SLIGHT ANGLE WITH RESPECTT TO THE AXES OF SAID WHEEL MEMBERS IN ORDER THAT THE YARN NORMALLY PROGRESSING AROUND ONE WHEEL MEMBER AND SAID SEPARATOR ROLL WILL DESCRIBE ENERALLY A HELIX, THE CONVOLUTIONS OF WHICH ARE SPACED APART, WHEREBY THE YARN ADVANCES ALONG THE ONE WHEEL MEMBER FROM THE INBOARD END THEREOF TO THE OUTBOARD END THEREOF DURING ROTATION OF SAID WHEEL MEMBERS, SAID PAIR OF WHEEL MEMBERS BEING POSITIONED ADJACENT SAID STRETCH PIN IN SPACED RELATION THEREWITH SO THAT SAID WHEEL MEMBERS ATE ADAPTED TO RECEIVE THE HEATED YARN FORTHWITH FROM SAID STRETCH PIN, AND MEANS FOR TAKING UP SAID YARN IN AN ORDERLY MANNER AFTER SAID YARN HAS PASSED BETWEEN SAID PAIR OF WHEEL MEMBERS AND AROUND SAID SEPARATOR ROLL A PLURALITY OF TIMES.
