  • Patent number: 4747372
    Abstract: The animal tether comprises an upright tube connected at an upper end to the end of a lateral tube. The apparatus is rotatably mounted on a base member upstanding shaft. Extending outwardly of the tubes a tether line together with a leash line is attached to an animal. The tether line is further engaged in reciprocal turns of line with a pair of pulley blocks which in response to, and animal movement shortens the distance between blocks. This in turn lifts a weighted body slidably disposed within the tube thereby applying tension on the animal leash line to prevent the leash line from entanglement.
