Abstract: A remotely controlled twin-jet monitor apparatus is mounted on the end of an articulated water-conducting boom or arm, and is so constructed that the two jets emanating therefrom never create any resultant torque about the vertical axis through the mast for the boom. Accordingly, the boom may be made extremely large yet light in weight, and may be manipulated by small and low-power motor means. Means are provided to effect simultaneous rotation of both jets, and to change the angles of the jets relative to a predetermined plane, but without creating the indicated resultant torque.

Abstract: A low-friction swivel joint has incorporated therein a worm wheel, the latter being rotated by a worm driven by a fluid motor. A second and corresponding swivel joint is also provided, being driven by fluid which is passed through the first-mentioned joint in order that there will be not twisting of pipes or conduits. The passage of fluid through the first-mentioned joint is effected by transfer rings and associated grooves and passages.

Abstract: The low-friction swivel joint in the hydraulic monitor has incorporated therein a worm wheel, the latter being rotated by a worm driven by a fluid motor. A second and corresponding swivel joint is also provided, being driven by fluid which is passed through the first-mentioned joint in order that there will be no twisting of pipes or conduits. The second joint effects rotation of a portion of the monitor about a horizontal axis, whereas the first-mentioned joint effects rotation of the monitor about a vertical axis.
