The ball-storage runways 50 comprise inclined floor members 54, 54ª, 54^{b}, each having longitudinally a slight downward inclination in the direction of the arrows. These runways also comprise longitudinally extending walls 55, 56, 57, 58, one end of the wall 55 being curved to meet one end of the wall 57, leaving a passageway 59 between it and one end of the wall 56. One end of the wall 58 is similarly curved to meet one end of the wall 56, leaving a passageway 60 between it and one end of the wall 57. Thus are provided parallel runways 61, 62 and 63, with passageways from one to the other, whereby a ball deposited in runway 61 will move continuously from that end of the series of runways to the other end. The runway 61 is provided with an end wall 61ª, and adjacent thereto the longitudinal wall 55 is provided with an opening 61^{b} to permit the passage therethrough successively of balls from the energy-storing wheel 19 to the runway 61. Projecting through the standard 16^{b} is a threaded bolt 63ª, the end of the shank of which is beveled, as clearly shown in Figs. 14 and 16, the function of which is to eject from the uppermost pocket 22 of the wheel 19, as the same revolves, the balls 23, and thrust them successively into the runway 61. At the lower end of the runway 63 is provided a laterally movable receptacle 64, which has a receiving capacity of one ball only. Said receptacle comprises a base 65 and perpendicular stop 66. The base 65 is connected to the floor member 54^{b} of the runway 63 by a horizontally disposed hinge 67, and to it is also affixed a plate 68, carrying a downwardly extending lever arm 69, which is formed at its lower extremity with an outwardly curving portion 70, which is adapted to engage with the spokes 25 of the wheel 24 and be thereby pressed inwardly, the result of which is to depress the outer end of the base 65 of the ball receptacle 64, inclining the same in such position that the ball therein will fall into the adjacent pocket of the wheel 24, the ball being prevented from falling therefrom on the opposite side by the stop 71 secured to the standard 16ª. The center of gravity of the lever arm 69 is such that when the curved lower portion is in its normal forwardly extended position the rear side of the base 65 of the receptacle 64 will be depressed and the forward side elevated, so that the forward side will normally project above the floor level of the runway 63 and serve as a stop to prevent more than one ball occupying any of the space within said receptacle at one time. The ball-storage runways 51 comprise inclined floor members 72, 72ª, 72^{b}, each having a slight downward inclination longitudinally in the direction of the arrows. They also comprise longitudinally extending walls 73, [Illustration: _Fig. 12._ BANGERTER’S PERPETUAL TIME CLOCK]
