Abstract
A water-borne craft is supported by laterally spaced pontoons, wherein an open-topped receptacle mounted in the open space between the pontoons is movable between a fully elevated position wherein the bottom of the receptacle is at or above the water line of the craft and a fully lowered position wherein the bottom of the receptacle is submerged beneath the water line and the open top of the receptacle is above the water line. Water and materials are introduced into and mixed in the receptacle when in a fully lowered position, after which the mixture is pumped from the receptacle and discharged under pressure through a nozzle.
Claims16
A water-borne craft for floating on a body of water, comprising laterally spaced apart pontoons, a deck supported on and spanning the space between the pontoons, said deck having an opening therethrough between the pontoons, an open top receptacle carried by the deck and having opposite side walls, opposite end walls and a bottom wall, means supporting the receptacle from the deck for selective movement through the opening to a lowered position with the bottom wall of the receptacle submerged in the water below the water line of the craft and to a raised position with the bottom wall of the receptacle above the water line of the craft, one of said receptacle walls having an opening therethrough in open communication with the body of water when the receptacle is in its lowered position for flow of water into the receptacle, means carried by the craft for introducing a material into the receptacle for forming an aqueous mixture of the material and the water therein, and means connected with the receptacle for discharging the aqueous mixture over a desired surface, whereby the material may be mixed with water from the surrounding body of water thus eliminating storage of water on the craft, and the receptacle may be raised to enable relatively unimpeded movement of the craft through the body of water.
A water-borne craft which includes a deck having a receptacle-receptive opening therein;
- a receptacle having bottom, opposite side and end walls, means connecting said receptacle to said deck for selective movement between a fully raised position wherein the bottom wall of the receptacle is disposed at or above the water line of the craft, and a fully lowered position for disposing a portion of the receptacle and the bottom wall submerged beneath said water line, a hopper secured to and carried by said deck, and means for selectively controlling the gravitational discharge of the contents of the hopper into said receptacle.
A water-borne craft which includes a deck having a receptacle-receptive opening therein;
- a receptacle having bottom, opposite side and end walls, means connecting said receptacle to said deck for selective movement between a fully raised position wherein the bottom wall of the receptacle is disposed at or above the water line of the craft, and a fully lowered position for disposing the bottom wall submerged beneath said water line, said means connecting the receptacle to the deck for selective movement between fully raised and fully lowered positions comprising a pair of parallelogram linkages by which the side walls of the receptacle are connected to the deck;
- and means accessible above the deck for simultaneously actuating said linkages for disposing and locking said receptacle in and against accidental or unintentional dislodgement from its fully raised and lowered positions.
