A pulley
Pipe grooved at end of pipe with grooving machine. Butt grooved pipe or fitting together and slip rubber seal onto end of each grooved joint, apply light coating of grease made for grooved piping on rubber seal. Coat split coupling for joint with grease also and put coupling around joint and clamp together tightly.

That would most likely be a pulley. A pulley is essentially a wheel on an axle that usually has a groove in the middle of its circumference that holds a rope, cable, belt, or chain. Pulleys are used to transmit motion rotationally and apply force in the direction of said motion. Two or more pulleys makes a tackle. Hope this is what you were looking for.
A Pulley This works by changing the direction of force around the wheel, which also provides reduced friction to the ropes movement. -Examples Include: Window Blinds, Flagpole pulleys, rock climbing pulleys, and some clotheslines.

a wheel with a grooved rim around which a cord passes. It acts to change the direction of a force applied to the cord and is chiefly used (typically in combination) to raise heavy weights.
