Combination cleaning, fountain and therapeutic whirlpool apparatus for swimming pools

Claim 2

A swimming pool and servicing system comprising: a pool wall; a pump discharge delivery line extending to said wall; a delivery outlet in said wall at the end of said line; and a pool-servicing unit having a readily detachable fitting for coupling connection to said outlet to receive therefrom a pumped flow of water for delivering a servicing flow into the pool; said servicing unit comprising an elbow tube projecting from said fitting and including a nozzle which projects upwardly through the pool surface when the fitting is coupled to said outlet, whereby to deliver a deCorative fountain jet.

Claim 3

A swimming pool and servicing system comprising: a pool wall; a pump discharge delivery line extending to said wall; a delivery outlet in said wall at the end of said line; and a pool-servicing unit having a readily detachable fitting for coupling connection to said outlet to receive therefrom a pumped flow of water for delivering a servicing flow into the pool; said servicing unit comprising a Tee fitting having at one end thereof means for coupling the same to said outlet, having at an opposite end a delivery nozzle aligned with said coupling means so that the discharge from said outlet will be directed therethrough, and having a breather tube extending at right angles from the common axis of said nozzle and coupling means and adapted to extend upwardly through and above the pool surface when said unit is coupled to said outlet, said unit being operable to draw air into the stream of water flowing through said tee fitting with an aspirating action and to mix it with the water flow so as to deliver from said nozzle a mixture of air bubbles and water for creating a boiling agitation of the adjacent surface area of the pool.

Claim 4

A swimming pool and servicing system comprising: a pool wall; a pump discharge delivery line extending to said wall; a delivery outlet in said wall at the end of said line; and a pool-servicing unit having a readily detachable fitting for coupling connection to said outlet to receive therefrom a pumped flow of water for delivering a servicing flow into the pool; said servicing unit comprising a Tee fitting having at one end thereof means for coupling the same to said outlet, having at an opposite end a delivery nozzle aligned with said coupling means so that the discharge from said outlet will be directed therethrough, and having a breather tube extending at right angles from the common axis of said nozzle and coupling means and adapted to extend upwardly through and above the pool surface when said unit is coupled to said outlet, said unit being operable to draw air into the stream of water flowing through said tee fitting with an aspirating action and to mix it with the water flow so as to deliver from said nozzle a mixture of air bubbles and water for creating a boiling agitation of the adjacent surface area of the pool.

Claim 5

A swimming pool comprising: a pool wall; a pump discharge delivery line extending to said wall; a delivery outlet in said wall at the end of said line; and a pool-servicing unit having a readily detachable fitting for coupling connection to said outlet to receive therefrom a pumped flow of water for delivering a servicing flow into the pool; said outlet comprising a socket set into the pool wall, opening into the pool, and having a coupling throat, and said fitting comprises a stem receivable in said throat, said throat and stem having cooperating bayonet coupling means for attaching said fitting to said socket.

Claim 6

A swimming pool comprising: a pool wall; a pump discharge delivery line extending to said wall; a delivery outlet in said wall at the end of said line; and a pool-servicing unit having a readily detachable fitting for coupling connection to said outlet to receive therefrom a pumped flow of water for delivering a servicing flow into the pool; said outlet comprising a socket set into the pool wall, opening into the pool, and having a coupling throat, and said fitting comprises a stem receivable in said throat, said throat and stem having cooperating bayonet coupling means for attaching said fitting to said socket.

Claim 7

A pool system as defined in claim 3: said bayonet coupling means further functioning to secure said servicing unit in a selected position of orientation around the coupling axis; said unit comprising a fountain delivery nozzle projecting upwardly through the pool surface when thus oriented.

Claim 8

A pool system as defined in claim 3: said bayonet coupling means further functioning to secure said servicing unit in a selected position of orientation around the coupling axis; said unit comprising an air induction tube projecting upwardly from said fitting through the pool surface when thus oriented, and said unit including a nozzle for delivering into the pool a surface agitating mixture of the water flow through said fitting and air drawn into said flow through said induction tube.
