ABSTRACT:
An elongated shaft is adapted to be connected at one end with a breeching bar transversely engaging the rump of a cow and having a windlass connected with its other end. Friction grip means transversely surrounds the shaft intermediate its ends and projects laterally therefrom. A remote end of the grip means is connected with one end of a flexible obstetrical member adapted to be connected at its other end with an unborn calf. A windlass is connected with the grip means adjacent the shaft so that when tension is applied to the line and obstetrical member the grip means is slidable relative to the shaft and frictionally grips the shaft in a binding action upon release of tension on the line or obstetrical member.
