inserted into the well casing 20 casing junction assembly 28 a lower edge 83 of the orienting key 82 fig6 contacts the profile 74 fig8 continued downward movement of the landing tool 40 causes the orienting key 82 to move along the profile 74 and into engagement with the orienting slot 70 thereby rotating the landing tool 40 and any attached items into alignment with the diverter 28 and the first and second lateral wellbores 16 18 fig3 and 4 the lower edge 83 of the orienting key contacts a lower ledge 71 of the orienting slot 70 which restricts any further downward movement as the orienting key 82 moves into the orienting slot 70 the locking key 88 is longitudinally and radially aligned with the locking slot 72 as the lower edge 83 of the orienting key bottoms out on the lower ledge 71 of the orienting slot 70 the locking key 88 will be moved into the locking slot 72 under force from the locking key spring 92 any upward movement is then prevented by contact of the upper edge 89 of the locking key 88 with the upper edge 73 of the locking slot 72 0040 fig1 shows a multilateral well 10 having packers 24 26 located within the first and second lateral wellbores 16 18 a diverter 168 which is a part of the casing junction assembly 28 is shown set within the main wellbore 12 proximal the junction of the main wellbore 12 and the lateral wellbores 16 18 the diverter 168 can be positioned within the well in numerous ways for example the diverter 168.
