Slip releasing apparatus

摘要

The slip releasing apparatus described herein includes a unitary slip member having wall engaging teeth located in diagonally opposite upper and lower ends and carries a pair of releasing pins mounted therein that project inwardly therefrom. The pins are disposed in recesses or holes formed in a slip carrier member that extends through the slip member. The recesses are configured in the carrier member so that an upward pull on the carrier member moves a release surface onto the carrier member into engagement with the pins in the slip member to cause pivotal or rotational movement of the slip member about a fulcrum formed by the engagement between the teeth on the lower end of this slip member and the pipe in which the slip member is run.
