Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
112 words
THE METHOD OF INSTALLING, WITHIN A RECESS IN A CARRIER PART, AN ELEMENT HAVING EXTERNAL THREADS WITH A FIRST PORTION OF SAID EXTERNAL THREADS HAVING SERRATIONS FORMEND THEREON AND A SECOND PORTION BEING LOCATED AXIALLY INWARDLY OF SAID FIRST PORTION; SAID METHOD INCLUDING SCREWING SAID EXTERNAL THREADS INTO ENGAGEMENT WITH INTERNAL THREADS FORMED IN SAID CARRIER PART, THEN DRIVING SAID FIRST PORTION OF THE EXTERNAL THREADS AXIALLY RELATTIVE TO SAID SECOND PORTION THEREOF AND RELATIVE TO SAID CARRIER PART THREADS, AND THEREBY FORCING SAID SERRATIONS OF SAID FIRST PORTION OF THE EXTERNAL THREADS AXIALLY INTO ADJACENT PORTIONS OF SAID CARRIER PART THREADS TO BITE THEREINTO AND LOCK THE ELEMENT AGAINST UNSCREWING ROTATION.
Claim 2
Independent Claim
112 words
THE METHOD OF INSTALLING, WITHIN A RECESS IN A CARRIER PART, AN ELEMENT HAVING EXTERNAL THREADS WITH A FIRST PORTION OF SAID EXTERNAL THREADS HAVING SERRATIONS FORMEND THEREON AND A SECOND PORTION BEING LOCATED AXIALLY INWARDLY OF SAID FIRST PORTION; SAID METHOD INCLUDING SCREWING SAID EXTERNAL THREADS INTO ENGAGEMENT WITH INTERNAL THREADS FORMED IN SAID CARRIER PART, THEN DRIVING SAID FIRST PORTION OF THE EXTERNAL THREADS AXIALLY RELATTIVE TO SAID SECOND PORTION THEREOF AND RELATIVE TO SAID CARRIER PART THREADS, AND THEREBY FORCING SAID SERRATIONS OF SAID FIRST PORTION OF THE EXTERNAL THREADS AXIALLY INTO ADJACENT PORTIONS OF SAID CARRIER PART THREADS TO BITE THEREINTO AND LOCK THE ELEMENT AGAINST UNSCREWING ROTATION.
Claim 3
Dependent Claim
96 words
THE COMBINATION COMPRISING A CARRIER PART CONTAINING A BORE HAVING FORMED THEREIN AN INTERNAL THREAD AND A THREAD GROOVE BETWEEN SUCCESSIVE TURNS OF SAID INTERNAL THREAD, AND AN ELEMENT SCREWED INTO SAID BORE AND HAVING AN EXTERNAL THREAD, SAID EXTERNAL THREAD HAVING A FIRST PORTION MATING WITH SAID INTERNAL THREAD AND RECEIVED WITHIN A PORTION OF SAID THREAD GROOVE, AND SAID INTERNAL THREAD HAVING A SECOND PORTION WHICH IS SERRATED AND IS DISPLACED AXIALLY INTO THE MATERIAL OF AN ADJACENT TURN OF SAID INTERNAL THREAD TO FORM A LOCK THEREWITH PREVENTING UNSCREWING ROTATION OF SAID ELEMENT.
Claim 4
Dependent Claim
96 words
THE COMBINATION COMPRISING A CARRIER PART CONTAINING A BORE HAVING FORMED THEREIN AN INTERNAL THREAD AND A THREAD GROOVE BETWEEN SUCCESSIVE TURNS OF SAID INTERNAL THREAD, AND AN ELEMENT SCREWED INTO SAID BORE AND HAVING AN EXTERNAL THREAD, SAID EXTERNAL THREAD HAVING A FIRST PORTION MATING WITH SAID INTERNAL THREAD AND RECEIVED WITHIN A PORTION OF SAID THREAD GROOVE, AND SAID INTERNAL THREAD HAVING A SECOND PORTION WHICH IS SERRATED AND IS DISPLACED AXIALLY INTO THE MATERIAL OF AN ADJACENT TURN OF SAID INTERNAL THREAD TO FORM A LOCK THEREWITH PREVENTING UNSCREWING ROTATION OF SAID ELEMENT.
