Self-propelled floating dock and separator filter assembly for treating polluted water surfaces and nautical works

Claim 1

A self-propelled floating device for removing pollution from water surfaces which device comprises, in combination: a. two longitudinal caissons which are substantially parallel and spaced from one another and having front and rear ends, b. a bottom floor extending between and joining the caissons at their lower portions, c. a first upstanding transverse partition extending between and secured to the rear ends of the caissons, d. a second upstanding transverse partition extending between and secured to the caissons adjacent the rear ends thereof and spaced from the first upstanding transverse partition so as to define a compartment therewith, e. a door pivotally mounted to the bottom floor adjacent the front end of the caissons for removing the pollution, which door is adapted to be adjustably pivotable between a fully closed position at which point it serves to define an enclosure with the caisson, the bottom floor and the second transverse partition, and a fully opened position at which point its surface is substantially coplanar with the surface of the bottom floor, f. a vault formed in the bottom floor and defining a threesided, downwardly open upwardly inclined channel extending substantially from the front end of the caissons to the second upstanding transverse partition and a horizontal channel connected to and extending substantially from the inclined channel to the first partition, g. a motor with a helix mounted in the compartment with the helix being disposed within and enclosed by the horizontal channel such that the operation of the motor will cause the helix to rotate and create a strong current of water which is drawn into and through both the inclined and horizontal channels, thereby causing the device to move forward such that the door serves to remove the pollution from the water surface and collect same within the enclosure.
