Abstract
A carrier float is adapted to be propelled while floating in a pool of water. A manual control on the float operates control valves that control escape of propellant fluid from two outlets in such relation that forward propulsion and steering are achieved. Typically, a seat is provided in the float.
Claims12
In combination with a forwardly longitudinally oriented carrier float adapted to be propelled while floating in a pool of water, comprising
- (a) manual control means on the carrier float,
- (b) propellant fluid ducting on the float and having outlet means to be submerged in the pool, said fluid outlet means including two fluid jet outlets which are laterally spaced apart and from which propellant fluid may escape in jets at controllable rates, both outlets remaining fixed relative to the float and directed generally rearwardly relative to a forward propulsion direction of the float,
- (c) and other control means on the carrier float responsive to selective movement of said manual control means to variably control the escape of propellant fluid from said two outlets thereby to control the direction of propulsion of the float in the pool,
- (d) said other control means including valve means coupled to said manual control means, one portion of said ducting extending from said valve means to said outlets,
- (e) there being a tubular coupling on the carrier float exposed for connection to a flexible line to supply propulsion fluid under pressure to said outlets via said ducting, another portion of said ducting extending to said valve means from said tubular coupling.

- (c) and other control means on the carrier float responsive to selective movement of said manual control means to control the escape of propellant fluid from said outlet means thereby to control the direction of propulsion of the float in the pool,
- (d) said other control means including valve means coupled to said manual control means,
- (e) said ducting adapted to receive water under pressure, said valve means including handle structure adapted to be grasped, the handle structure supported for rotation in one direction to increase water delivery to one jet outlet and decrease water delivery to the other jet outlet, and for rotation in the opposite direction to decrease water delivery to said one jet outlet and increase water delivery to the other jet outlet,
- (f) said valve means including an inlet port and two outlet ports respectively communicating with said jet outlets, a passage communicating with said inlet port, a seat about said passage, a stopper cooperating with the seat, and said handle structure includes a grip part operatively connected with the stopper and movable from closed position in which the stopper is closed relative to the seat to selected release positions in which the stopper is selectively spaced from the seat to control release of water flow to at least one of said jet outlet ports.
