expansion coils, the wires H, H¹ will be pulled in the direction indicated by the arrows, the ends of the long arms of the levers L, L—through the movement of the shafts J, J—will rise, thereby, through the rods 40, 41, link 39 and rods 38, 37, raising the lever 35, and through the rod 34 actuating the pawl carrier 33, and through the pawls 31, 32, imparting rotary motion to the ratchet wheel 30, and, through it, to the shaft 18 and the power-storing wheel 19, said pawl carrier being returned to its normal position by the weight 36ª. Motion of said wheel and shaft in the reverse direction is prevented by means of a ratchet wheel 42, keyed to the collar 29, engaging the teeth of which wheel is a detent 43, carried by a plate 44, secured to the supports 45, affixed to the standard 16ª.
The hub member 26 of the power transmission wheel 24 is provided with a sprocket wheel 46, which is adapted to engage and drive a sprocket chain 47, and thereby drive the great wheel of a clock mechanism or gearing of any other machine adapted to the purpose.
Having shown the mechanism for driving the energy-storing wheel 19, which, as already stated, is keyed to the shaft 18, I will now describe the mechanism for driving the power transmission wheel 24, which runs loose on the shaft 18.
It will be seen from an inspection of [Fig. 16] that the wheel 19 is of greater diameter than the wheel 24.
Suitably mounted between said wheels, on cross-bars 48, 49, I provide a series of ball-storage runways designated in whole at 50 (see [Fig. 14]), and, as shown in [Fig. 16], these runways are laterally inclined downwardly from the wheel 19 to the wheel 24.
Similar ball runways designated in whole at 51 are provided at the lower portion of said wheels and between the same (Fig. 20), being mounted upon cross-bars 52, 53, but the last named runways are laterally inclined in the reverse direction to that of the runways 50.
The ball-storage runways 50 comprise inclined floor members 54, 54ª, 54b, 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 61b to permit the passage therethrough successively of balls from the energy-storing wheel 19 to the runway 61.
Projecting through the standard 16b 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.
