The second length (34) has a portion (42) of reduced diameter relative to that of the first length (32). The diameter of the first length (32) is dimensioned so that the bit segments (14) can initially collapse radially inwardly wholly onto an outer circumferential surface (38) of the length (32). The reduced diameter portion (42) is dimensioned so that when the bit segments (14) are disposed thereon, the bit segments (14) can pass through the drive sub (12) and bit locking sleeve (16). In use, when the bit segments (14) clamped to the drive sub (12) are collapsed onto the first length (32) and a down hole tool to which the retrieval head (10) is coupled is pulled upwardly, the bit segments (14) slide relative to and along the head (10) from the first length (32) by abutment of the bit segments (14) with the drive sub (12) and/or bit locking sleeve (16); to the reduced diameter portion (42) where the bit segments (14) together with the retrieval head (10) can pass through the locking sleeve (16) and the drill string to be retrieved. | ||||||
| 280 | Core drilling latch assembly | US339551 | 1999-06-24 | US6019181A | 2000-02-01 | Frederick J. Soinski; Donald Raymond |
| A core drilling latch assembly for use in terrestrial core drilling operations. The latch assembly incorporates features and elements which affect the flow of drilling fluids past the latch assembly and toward the drill bit, depending upon whether the latch assembly has contacted the landing ring in the drill string and whether the latch assembly has locked in place within the string. Accordingly, the latch assembly signals the drilling crew by pressure fluctuations when the latch assembly is in proper position within the drill string, and whether it is locked in position. | ||||||
