The error of all this lies in the fact that the four balls between B and A will not elevate the two balls between B and C for the reason that they are on a less inclined slope. As we would ordinarily state it, B C is a "steeper" incline. One ball between B and C by force of gravity pulls stronger toward C than one ball on B A will pull toward A. It is manifest, therefore, that an equilibrium requires a greater number of balls on B A than B C.
B A is longer and accommodates a greater number of balls than can be accommodated on B C. The number of balls that can be accommodated on the respective sides is always found to be such that the small number of balls between B C pull in the aggregate toward C the same as the greater number of balls between B and A pull toward A, and thus equilibrium is established.
It is manifest, therefore, that with the pull from B toward C equal to the pull from B toward A, the mechanism finds its balance and motion ceases. This is true of all similar devices.

HYDRAULIC AND HYDRO-MECHANICAL DEVICES
Enbom & Anderson's Pump
"June 13, 1882 U. S. Patent, No. 259514 was granted to Andro Enbom and John A. Anderson, of Augusta, Kansas, U. S. A., on
"Improvements in Pumps."
It seems probable that the inventors did not suspect, and that the patent office examiners did not discover that the device had in the claimed "Improvement" the essentials of self-motive power. An examination of the specifications clearly shows, however, that the claim of the inventors that "the water lifted by the pump is caused in its passage over the wheel A² to give power to the same and thus lessen the labor required," presupposes the principle of self-motive power. The following figure taken from the specifications and the following excerpt from the specifications illustrate the intended operation:
