摘要： A trenching assembly featuring a novel auger arrangement. The arrangement comprises an auger assembly and a digging chain rotatably connected to a trenching boom. The digging chain rotates, driven by a motor, to dislodge soil and creating a trench. The dislodged soil, or spoil, builds up near a projected path of the digging chain. The auger assembly operates to move the spoil from a projected path of the trench. The auger rotates independently from the digging chain and is positioned such that a projected width of the digging chain intersects a threaded length of the auger assembly. The auger may rotate faster than if driven by the digging chain, allowing the auger to have a smaller diameter than conventional augers. Further, the auger can be used in conjunction with a backfill blade to refill cleaned trenches without operation of the digging chain.

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.

摘要： A control system for a work machine. The control system allows an operator to selectively maintain control of a ground drive, a work tool, or both the ground drive and the work tool. The system provides a foot pedal movable between multiple positions. The foot pedal allows an operator to selectively hold the position of one or both of the ground drive control and work tool control. When the foot pedal is in a first position, the work tool control and ground drive control are not affected. When the foot pedal is in a second position, the position of the work tool control is maintained, while the ground drive control is not affected. When the foot pedal is in a third position, the position of the work tool control is maintained and the position of the ground drive control is maintained. A work tool control lock is used to prevent the work tool control from engaging when the foot pedal is in the second position or the third position.

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： A work (10) having a first work member and a second work member, both operated from a pivotal control station (22). In a preferred embodiment the work machine has a backhoe assembly (18) and a loader assembly (20) both supported on a frame and operable from the pivotal control station (22). The work machine may have left and right low-profile drive systems (72, 74) that allow the first work member to perform work outside and parallel to the longitudinal center axis (83) of the work machine (10). The work machine has a low-profile power source (70) and operator platform that allow unobstructed visibility of the first and second work members (18, 20) from the control station (22).

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.
