To quickly assess the difficulty of the text, read a short excerpt:
As K is attached to H, and H meshes with B, the motion of the train is again communicated with the propeller shaft, but in a direction opposite to that of the fly-wheel A. At first it will be difficult to see why holding the pinions F and J alternately will give opposite directions of rotation to B since it is evident that the gears G and K revolve about the engine shaft and their own spindle in the same direction in both cases. Reversal is not due to the reversal of the actual direction of B a...nd H-G-K but is due to a change in the relative velocities between the periphery of H and the velocity of the spindles about the engine shaft. It will be noted that J is larger than F, and that K is smaller than G, thus giving a higher rotational velocity to the triple gears H-G-K than would be the case with F held stationary. The ratios of the main gears H and B are, of course, the same "in both cases with the spindles still traveling at engine speed. With the higher rotational velocity of H-G-K obtained by holding J, the peripheral velocity of H at the point where it meshes with B is now greater than the velocity of the spindles so that the bottom of gear H forces B back faster than the fly- wheel carries the mass forward.
