Modular filter / circulation system and traveling main drain for in-ground swimming pools
First Claim
1. A modular water filtration and circulation system for use in a swimming pool containing water, said swimming pool having a bottom, sides, and upper side edges, said system containing the circulatory, filtration, and piping requirements for said swimming pool, comprising:
- (a) a modular housing mounted adjacent to an upper side edge of said pool and communicating with a surface of the water in the pool when the pool is filled;
(b) a skimming aperture in said modular housing through which water is skimmed from the surface of the water in the swimming pool;
(c) pump means within said modular housing, said pump means having an input vacuum side and an output pressure side;
(d) a filter within said modular housing for filtering liquids by passing them therethrough, said filter having(1) an intake port for supplying water to said filter and communicating with said output pressure side of said pump, and(2) an outlet port for carrying filtered water away from said filter;
(e) a bi-directional coupling mounted on said housing and enclosing a pressure member communicating with the outlet port of said filter and a vacuum member communicating with the input vacuum side of said pump,(1) said vacuum member drawing water from said swimming pool and not being connected to a swimming pool main drain, and,(2) said pressure member returning filtered water to said swimming pool; and
,(f) a plurality of pool discharge nozzles mounted on said housing and communicating with said filter outlet, said pool discharge nozzles returning filtered water to said swimming pool.

Abstract
The present invention is directed generally toward a modular apparatus for the circulation, filtration, and chlorination of water in an in-ground swimming pool. In more particular, the invention disclosed herein relates to a modular and transportable pool-side unit in which the entire filtration and circulation systems, as well as the lighting and chlorination systems, for the pool are contained. Additionally, the instant invention utilizes a novel traveling main drain, wherein the functions of a conventional pool main drain and an automated pool sweeper are combined. The traveling main drain is moved about the bottom of the pool by the expulsion of water through a single horizontally mounted jet, said jet being free to rotate in a horizontal plane about the central axis of the device and thereby seek another movement direction when the device becomes blocked. The traveling main drain is connected to the modular pool apparatus through a novel hi-directional water conduit, which contains both a pressure and a vacuum water line.

9. A water propelled traveling main drain for use with a source of pressurized water and a vacuum source, said traveling main drain being adapted to travel about a bottom of a swimming pool collecting debris therefrom, comprising:
-
(a) a wheel supported body, said body having an upper surface, a lower surface proximate to said pool bottom, and a body aperture passing therethrough for the taking of water from the bottom of the pool; (b) a vertical duct having an upper end and a lower end, said lower end communicating with said body aperture; (c) a junction mounted proximate to said upper end of said vertical duct, said junction containing a pressure compartment and a vacuum compartment, (1) said vacuum compartment in communication with said vacuum source and said upper end of said vertical duct, and, (2) said pressure compartment in communication with said source of pressurized water; (d) a horizontally directed jet drive nozzle for propelling said traveling main drain about the bottom of the swimming pool by force of the water expelled therefrom, said jet drive nozzle (1) having an inlet and an outlet, said inlet communicating with said pressure compartment of said junction and said outlet having a restricted terminus to increase the motive force produced by the water passing therethrough, (2) being rotatably mounted on said vertical duct and rotating freely in a horizontal plane thereabout, said outlet terminus being oriented to point radially away from said vertical duct, and, (3) urging said traveling main drain to move in a direction away from the orientation of said outlet terminus by expelling water therefrom. - View Dependent Claims (10, 11)
