Abstract
A tool for installing or removing a threaded member as for example a thread protector onto a second threaded member, as for example, the pin or box of an oilfield tubular, which has a jaw for selectively gripping an outer surface of a thread protector, a bridge interconnecting the jaw and a cam, the cam being selectively engageable with the inner surface of the thread protector, the cam being operatively connected to a lever for moving the cam from a first position out of contact with the inner surface of the thread protector to a second position in gripping engagement with the inner surface of the thread protector.
Claims16
A tool for installing or removing a first threaded member from a second threaded member, comprising:
- a bridge having an upper surface, a lower surface, a first end and a second end;
- a jaw having an arcuate jaw body, said jaw pivotally connected to said bridge by a pivot assembly, said pivot assembly comprising an elongate member extending through said upper and lower surfaces of said bridge and said jaw such that said jaw pivots in a circumferential direction around the long axis of said elongate member, said elongate member being selectively removable from said bridge and said jaw;
- a cam rotatably connected to said bridge, distally spaced from said jaw, said cam having a laterally outwardly projecting camming surface;
- and
- a lever, operatively connected to said cam, movement of said lever in a first direction causing movement of said cam in a first direction which decreases the distance between said jaw and said camming surface, said bridge being disposed between said cam and said lever, said arcuate iaw body having a first lateral surface facing away from said cam and a second lateral surface facing toward said cam, said second lateral surface being concave.
A tool for installing or removing a first threaded member from a second threaded member, comprising:
- an elongate, generally rectangular bridge having an upper surface and a lower surface a first end and a second end;
- a jaw having an arcuate jaw body, said jaw being pivotally connected to said bridge by a pivot assembly, said pivot assembly comprising an elongate member extending through said upper and lower surfaces of said bridge and said jaw such that said jaw pivots in a circumferential direction around the long axis of said elongate member;
- a cam rotatably connected to said bridge, distally spaced from said jaw, said cam having a laterally outwardly projecting camming surface;
- and
- a lever, operatively connected to said cam, movement of said lever in a first direction causing movement of said cam in a first direction which decreases the distance between said jaw and said camming surface, said bridge being disposed between said cam and said lever, said arcuate iaw body having a first lateral surface facing away from said cam and a second lateral surface facing toward said cam, said second lateral surface being concave.
