  • Patent number: 4115997
    Abstract: A timing attachment is secured to one side of a telephone instrument to indicate the elapsed time of a telephone conversation. The timing attachment or timer has an hourglass contained within an elongate cylinder which has an arm extending from the center thereof pivotally attached to a base member. The base is adhered to the side of the telephone instrument or other convenient surface. The cylinder and hourglass therein is rotated in a substantially vertical plane 180.degree. at a time to allow the sand or other material to flow from one end of the hourglass to the other to measure a predetermined elapsed period of time. Various automatic indicating means cooperate with the cylinder to indicate the total number of minutes or time periods which have elapsed during a telephone conversation. The indicating means may be a rotatable cap with indicia around the periphery thereof in successive increments of the predetermined elapsed time periods corresponding to the number of times the cylinder has been rotated.
