Abstract

1305847 Wells &c CAMCO Inc 9 July 1971 [27 Nov 1970] 32375/71 Heading E1F In a well tool slip assembly comprising slips 30, expanders 18, 20 having dovetail connections with the ends of the slips, and a centring sleeve 40 for keeping the slips in longitudinal alignment, the sleeve has an aperture for each slip so that the slips may be moved inwardly into the sleeve to permit the making of the connections. After the members 18, 20, 30, 40 have been assembled and mandrel 12 is passed through the assembly to engage the slip setting threads 32, and the expander 20 is fixed against longitudinal movement on the mandrel by shear pins 34 engaging in a mandrel groove 36. Rotation of the mandrel which would tend to unthread the expander 32 is prevented by pins 54, 56 on the expander 18 and mandrel respectively.
