Abstract: 18,558. Quick, G. Aug. 23. Manumotive vehicles motor cycles.-Relates to manumotive and powerdriven vehicles. Fig. 1 shows a tricycle, propelled by two persons. One sits in the chair-like seat, and propels the vehicle by means of hand-levers B, while the other stands on a platform behind the seat, and assists in the propulsion by putting his weight on the stirrup E, which is suspended on a lever C forming a part of a rocking-frame comprising the hand-levers B and the lever D. The single rear wheel is the driver, and is rotated by a pair of free - wheel clutches, actuated by cords, attached to the lever D. The cord T' is attached at one end to the lever D, and is wound round, and attached to a grooved pulley G', Fig. 6, loosely-mounted on the axle of the driving-wheel. When the hand-levers are swung upwards, the cord T' is pulled forwards and rotates the pulley G<1> in the direction of the arrow. The pulley carries pawls engaging ratchet teeth on the hub of the driving-wheel. When the hand-levers are swung downwards, and the lever D moves towards the rear, an elastic cord or spring S rotates the pulley G<1> in a direction opposite to that shown by the arrow. When the pulley reaches the limit of its backward movement, a fixed stop A arrests the movement of the arm f projecting from a loose disc F<1>. This disc is thus rotated against the pull of the spring t, and, by means of pins, lifts the pawls out of engagement with the ratchet teeth, so that the driving-wheel is quite free. The cord T is wound at one end round a pulley D' carried by the arm D, Fig. 2, and at the other end is wound round a grooved pulley G, in the opposite direction to the cord T'. When the hand-levers B are swung upwards, the pulley G is rotated in the direction shown by the arrow in Fig. 1. When the hand-levers move in the other direction, a spring d, by means of a cord V, rotates the pulley G, and the driving-wheel in the forward direction. The pawls carried by the pulley G are thrown out of gear in a similar way to those on the pulley G'. When the arm D reaches the end of its forward stroke, a stop A encounters a lever k, and throws the pawl W out of engagement with the ratchetwheel on the pulley D'. The cord T' is thus unwound by the movement of the pulley G. When the lever D moves towards the rear, a spring in the pulley D' re-winds the cord T'. By means of a bell crank Z, Fig. 1, connected by a wire to a lever X, the pawl W can be held out of gear, when going up hill for instance, so that the vehicle is driven through the cord T alone. To stop the vehicle, the hand-lever R is operated to rock the bell crank N, lower the framing M, and place the wheel I in contact with the ground. The wheel I is thus rotated, and, by means of a pinion on its spindle, rotates the gear-wheel K and a pulley, which, by means of a cord, rotates the pulleys L', G, and extends the spring d. The momentum of the vehicle is thus stored in the spring d, and is utilized for propulsion. In a modification, the wheel I and framing M are dispensed with, and, to apply the brake, a loose chain-drum is, by the movement of a lever, locked to the hub of the driving-wheel. This chain-drum drives a countershaft, which again, by means of a second chain, rotates the pulley G, and extends the spring d. The pulley G may be serrated to engage with a locking-pawl O, which is pulled into engagement by a spring when the bell crank Q is operated. The wheel I may have a rubber tyre, protected by a metal slipper, at the place when it skids after the spring d is fully extended. A motor of any kind may be used to operate the rocking-frame B, C, D, or may be used to actuate the clutches through other means,
