Chain receiving and engaging means for a parting tool

Claim 1

A CUTTER FOR PARTING A FRACTURABLE MEMBER WHICH COMPRISES IN COMBINATION, A CUTTING CHAIN HAVING FIRST AND SECOND ENDS ADAPTED TO BE PLACED AROUND SAID FRACTURABLE MEMBER AND TO EXERT A PARTING PRESSURE THERETO WITHOUT ROTATION OR OSCILLATION OF SAID CHAIN THEREABOUT, SAID COMPRISING CHAIN LINKS, LATERALLY EXTENDING PINS INTERCONNECTING SAID CHAIN LINKS AND PARTING MEMBERS FOR ENGAGING AND PARTING SAID FRACTURABLE MEMBER MOUNTED ON SAID PINS BETWEEN SAID CHAIN LINKS, SAID PINS EXTENDING LATERALLY FROM THE SIDES OF THE LINKS, AND A PRESSURE CLAMP MEANS INCLUDING A FIRST PRESSURE CLAMP JAW SECURED TO SAID FIRST END OF SAID CHAIN AND A SECOND PRESSURE CLAMP JAW HAVING CHAIN RECEIVING AND ENGAGING MEANS THEREON TO RECEIVE AND ENGAGE SAID PINS AT A LOCATION DICTATED BY THE SIZE OF SAID FRACTURABLE MEMBER, SAID SECOND PRESSURE CLAMP JAW COMPRISING TWO SPACED JAW MEMBERS SPACED APART AT A DISTANCE GREATER THAN THE LENGTH OF THE PINS, SAID SPACED JAW MEMBERS HAVING RESPECTIVELY INTERNAL LATERALLY-EXTENDING BOSS MEANS HAVING OPPOSED FACES LATERALLY SPACED APART FROM EACH OTHER FOR A DISTANCE LESS THAN THE LENGTH OF THE PINS AND GREATER THAN THE WIDTH OF THE CHAIN LINKS, SAID SPACED JAW MEMBERS AND SAID BOSS MEANS DEFINING CHAIN RECEIVING AND ENGAGING MEANS WHEREBY SAID CHAIN MAY BE WRAPPED AROUND SAID FRACTURABLE MEMBER WITH THE SECOND END PULLED THROUGH SAID CHAIN RECEIVING AND ENGAGING MEANS, SAID BOSS MEANS RESPECTIVELY HAVING FIRST AND SECOND SOCKETS, SAID FIRST SOCKETS BEING IN TRANSVERSE ALIGNMENT WITH EACH OTHER TO RECEIVE SAID PINS, SAID SECOND SOCKETS BEING IN TRANSVERSE ALIGNMENT WITH EACH OTHER TO RECEIVE SAID PINS, SAID FIRST SOCKETS HAVING RESPECTIVELY A FIRST EDGE AND A SECOND EDGE WITH A DWELL SURFACE THEREBETWEEN, SAID FIRST EDGE OF SAID FIRST SOCKETS CONSTITUTING A PIN ENTRANCE EDGE AND SAID SECOND EDGE CONSTITUTING A PIN EXIT EDGE, SAID DWELL SURFACE OF SAID FIRST SOCKETS HAVING A DEPTH MEASURED WITH RESPECT TO THE PIN EXIT EDGE WHICH IS LESS THAN THE RADIUS OF THE PINS, SAID SECOND SOCKETS HAVING RESPECTIVELY A FIRST EDGE AND A SECOND EDGE AND A DWELL SURFACE THEREBETWEEN, SAID FIRST EDGE OF SAID SECOND SOCKETS CONSTITUTING A PIN ENTRANCE EDGE, SAID DWELL SURFACE OF SAID SECOND SOCKETS HAVING A DEPTH MEASURED WITH RESPECT TO THE PIN ENTRANCE EDGE WHICH IS LESS THAN THE RADIUS OF THE PINS, SAID BOSS MEANS HAVING RESPECTIVELY A PIN GUIDE WALL SURFACE EXTENDING FROM THE PIN EXIT EDGE OF SAID FIRST SOCKETS AND TOWARDS THE PIN ENTRANCE EDGE OF SAID SECOND SOCKETS, WHEREBY SAID CUTTING CHAIN UPON BEING WRAPPED AROUND SAID FRACTURABLE MEMBER MAY BE PULLED THROUGH SAID CHAIN RECEIVING AND ENGAGING MEANS AND THEN DRAWN TIGHT ABOUT SAID FRACTURABLE MEMBER WITH SAID PINS RIDING OVER SAID PIN ENTRANCE EDGE OF SAID FIRST SOCKETS, SAID DWELL SURFACES THEREIN, AND SAID PIN EXIT EDGE THEREOF, AND THEN ALONG SAID PIN GUIDE WALL TOWARDS SAID SECOND SOCKETS WITHOUT CATCHING THE PINS, SAID FIRST SOCKETS AND SAID SECOND SOCKETS BEING POSITIONED WITH RESPECT TO EACH OTHER THAN THE DISTANCE BETWEEN THE CENTER OF A PIN IN THE FIRST SOCKET AND THE CENTER OF A PIN IN THE SECOND SOCKET IS GREATER THAN THE DISTANCE BETWEEN TWO ADJACENT PINS AND LESS THAN THREE ADJACENT PINS, ENGAGEMENT OF A PIN IN SAID SECOND SOCKETS AND THE INTERMEDIATE POSITIONING OF A FIRST ADJACENT PIN BETWEEN SAID FIRST AND SECOND SOCKETS PLACING A SECOND ADJACENT PIN IN A POSITION TO ENGAGE THE DWELL SURFACE OF SAID FIRST SOCKETS, THE DISTANCE BETWEEN THE CENTER OF SAID FIRST ADJACENT PIN AND THE INSIDE SURFACE OF THE CIRCUMFERENTIAL SURFACE OF THE PIN IN THE FIRST SOCKETS BEING LESS THAN THE DISTANCE BETWEEN THE CENTER OF THE FIRST ADJACENT PIN AND THE PIN ENTRANCE EDGE OF SAID FIRST SOCKETS WHEREBY SAID PIN IN SAID FIRST SOCKETS IS HELD THEREIN, SAID DWELL SURFACE OF SAID FIRST SOCKETS MEETING WITH SAID PIN EXIT EDGE THEREOF AND DEFINING A NON-CATCHABLE SLOPE WHICH MAKES AN INCLUDED OBTUSE ANGLE WITH RESPECT TO A LINE PASSING THROUGH THE CENTER OF SAID PIN IN SAID FIRST SOCKETS AND THE CENTER OF THE FIRST ADJACENT PIN.
