Abstract
An indicating device for repeatedly indicating variation in the load on a part such as a polish rod of a pump is disclosed. The indicating device includes an indicator for providing an indication when current flows through the indicator, a switch for moving between an opened and a closed position and for permitting current to flow through the indicator when the switch is in one of the open and closed positions, and reciprocating moving means for reciprocally moving in response to reciprocating movement of the part and for moving the switch to the one of the open and closed positions once during each cycle of the reciprocating movement of the reciprocating moving means. The indicator thus provides the indication once during each cycle of the reciprocating movement of the part and thus repeatedly indicates reciprocating movement of the part.
