Description: "The Chica Ballapura engine consists of two upright rollers, A, the heads of which are formed into double spiral screws, B, which work in one another, so that when an ox is yoked to the long curved lever C, and goes round, one of the upright rollers, being connected with the lever, is made to revolve, and its screw carries the other one round but in the opposite direction." — Chambers, 1881
