Mounted upon a collar 29, which is keyed to the driving shaft 18, is a ratchet wheel 30, engaging the teeth of which are two pawls 31, 32, secured to one arm of a double-arm pawl-carrier 33, the other arm of which is connected by a rod 34 to a lever 35, one end of which lever is pivotally connected to a standard 36, secured to the frame, and the other end of which is provided with a weight 36ª. Near the inner end of the lever 35 connection is made by means of the connecting rods 37 and 38, link 39 and rods 40, 41, with two levers indicated at L, L, which are adapted to take power from the expansion coils heretofore described, through the coil shafts J, J, to which shafts are also connected the coil levers I, I, the ends of the latter being connected to the strips G, G^{x} of the expansion coil by the wires H, H¹, as already set forth and clearly illustrated in Figs. 2, 3, 5, 6 and 7. As illustrated in Fig. 13, upon contraction of the [Illustration: _Fig. 8._ _Fig. 9._ _Fig. 10._ _Fig. 11._ BANGERTER’S PERPETUAL TIME CLOCK] 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.
