摘要： A dual-member pipe joint (24) having an outer member (26) and an inner member (28) which is disposed coaxially within the outer member (26). Both the outer member (26) and the inner member (28) have a pin end and a box end. The pin end of the outer member is threadable to the box end of another outer member. The pin end (94) of the inner member (28) is geometrically shaped. The box end (96) of the inner member nonthreadably receives the pin end (94) of another inner member in 'slip-fit' connection. 'Slip-fit' means the pin end of the inner member slides into the box end (96) of a like inner member and forms a connection that is capable of transmitting torque. The pipe joint may be connected to a drill string in a single action with just one connection. This dual-member pipe joint reduces boring time as compared to boring with conventional dual-member pipe joints, in which both the inner and outer members are threadably connected and thus require two pipe connections. This dual-member pipe joint is usable as a system of pipe, and as part of a boring machine.

摘要： An automatic pipe handling device (10) is disclosed which includes a support frame (12) mounted on a boring device. Removable pipe racks (16, 80, 130, 140) can be placed in position on the support frame (12) to deliver pipe to the spindle axis or to remove pipe therefrom as required. The pipe sections are removed from the pipe rack and positioned on the spindle axis by pipe grippers (32) mounted on hydraulic cylinders (28, 30) mounted on a rotating longitudinal shaft (20). The grippers and shaft similarly return the used pipe sections for storage to the pipe rack. In one pipe rack (16), an S-shaped guide path (72) is used. In another pipe rack (80), a plurality of rows (88, 90, 92) of pipe sections are used.
