A, is the fore wheel of the carriage to be taken up, and .r the axle; upon the axle is placed the sheave F, within which coils the rope C, the sheave runs loo.«e upon the axle, and is thrown in and out of gear with it by the clutch D, worked by the lever e, the end of the rope is made fast to the sheave, and the rope coils over itself, the ro])e may be of any convenient length, about lOU yards I consider sufiicient. B, B, are two supports depending from the framing of the carriage to support the axle more steadily. L, is tlie framing of the last carriage of the train, to the side of the framing is fixed the hook K, a post h, is placed at a proper distance, upon which is fixed the hook or bolt /, the ring g, fastened to the end of the rope c', is then hooked upon the bolt /; the hook k, of the passing carriage hooks into the ring and carries away the rope, which then drags the carriage to which the pulley is attached along with it; but the carriage is dragged after the train by a velocity so much slower than the train, as is due to the quantity of rope uncoiled for every revolution of the wheel A, for example, if the train passed over five yards, and the rope uncoiled four yards, the space passed over by the carriage at starting would be one yard or one-fifth the velocity of the train, but the velocity of the carriage is increasing as the coil of rope becomes less, and it moves slower than the train until all the rope is unwound, then afterwards the rope winds upon the axle, when the carriage then moves at a greater velocity than the train, and in the same proportion as the rope coils up wlien it at last over- takes the train, then when it has arrived close u]i to the last c
