1. A pacer-timer device intended to be worn about a portion of an individual'"'"''"'"'s body to provide audible pacing signals to the individual for pacing of the individual'"'"''"'"'s body movements in jogging, walking and running, the device comprising, in combination:

  • a housing of a rectangular hollow box-like configuration having a flat vertical front surface, a flat vertical back surface, a flat horizontal top surface, a flat horizontal bottom surface, and opposed vertically extending flat side wall surfaces;

    a slot extending longitudinally through said opposed side wall surfaces adjacent said back wall surface and opening out of said side wall surfaces;

    an elongated flat rectangularly configured flexible strip like belt of a cross-sectional area to pass freely through said slots of said housing side wall surfaces, said belt intended to pass about an individual'"'"''"'"'s waist for adjustably retaining said housing to the individual'"'"''"'"'s body;

    an earphone intended to be worn in an individual'"'"''"'"'s ear and having an electrical cord extending outwardly therefrom;

    an earphone jack disposed in said housing top surface adapted to have said earphone cord electrically connected thereto;

    a rectangular opening provided in said housing front wall surface and opening into said housing interior;

    a slot provided in one of said side wall surfaces adjacentmost said front wall opening and disposed parallel to and adjacent said front wall surface;

    a flat circular disc member having a knurled circumferal edge and rotatively affixed about its axis interiorlY of said housing to have a face surface thereof disposed rearwardly of said front surface opening and to have a portion thereof projecting outwardly of said housing interior through said slot adjacent said front wall surface to be readily engaged about its circumference by an individual'"'"''"'"'s finger to effect manual rotation of said disc;

    a plurality of numerically increasing indicia in the form of indicating numerals sequentially arranged on said front surface of said disc spaced equally about the circumference thereof in positions to be selectively oriented with said front surface opening upon rotation of said disc for visual indication of the relative position of said disc about its axis to an individual wearing said housing;

    a source of electrical energy provided by a battery mounted in said housing;

    an electrical circuit disposed within said housing interior to provide an electrical signal output in the form of timing impulses to said earphone of a selected frequency range, said electrical circuit including a first and second transistor of the NPN type, a third transistor of the PNP type, a first through fourth diode, a first through third capacitor, a first through third fixed resistor, a first variable resistor, a second variable resistor, said first and second transistors defining a multi-vibrator circuit in conjunction with associated ones of said components to provide an output signal of pulses selectable in frequency in the range of from 0.4 seconds to 3.0 seconds, said third transistor receiving said output signal and amplifying the same to energize said earphone coil to provide audible signals in said earphone varying in accord with said output signal; and

    said disc being manually connected to said first and said second variable resistors with rotation of said disc varying the resistance of said variable resistors to effect the tuning of the multi-vibrator circuit in a manner to select the desired frequency output signals.
