Abstract of the Disclosure A wireline latching apparatus and method of use with wireline instruments for measuring temperature and pressure downhole in flowing oil and gas wells. The latching apparatus includes a tubular body for connection to the instru- ment. Three arms are mounted in the tubular body pivotally so that their upper ends open outward. A downwardly facing shoulder is located in the well pipe in the area where the measurements are to be taken. An actuating mechanism is operable to open and close the arms so that their upper ends bear against the shoulder. The instrument with the latching mechanism is lowered into the well and positioned so that the arms are adjacent the shoulder. The. arms are opened to engage the shoulder and the wireline tensioned to prevent whipping of the line as fluid flows past. -2-
