Stain remover for swimming pools, apparatus and method

Claim 2

Stain remover apparatus for swimming pools comprising a bowl member open at its lower end and adapted to enclose and isolate a pool wall stain area, enclosure means associated with said bowl member defining a chamber for a stain remover liquid, a passageway interconnecting said chamber and the interior of said bowl member, and valve means to selectively open and close said passageway, said valve means including means automatically operable responsive to the bringing into engagement of said bowl member with the pool floor to open said passageway and automatically operable responsive to the removal of said bowl member from engagement with the pool floor to close said passageway.

Claim 3

The apparatus of claim 1, said enclosure means being carried by said bowl member, said apparatus further comprising a container for stain remover liquid located on the pool deck, and means including a hose connecting said container with said chamber for siphon-action dispensing of stain remover liquid from said apparatus.

Claim 4

Stain remover apparatus for swimming pools comprising a bowl member open at its lower end and adapted to be placed in enclosing relation to a pool wall stain, enclosure means associated with said bowl member defining a chamber for a stain remover liquid, a passageway interconnecting said chamber and the interior of said bowl member, and a valve member to open and close said passageway, said valve member comprising a vertically depending stem which normally extends past the lower end of said bowl member, the opening of said passageway being accomplishable by pressing said stem against the pool floor to raise said valve member relative to said bowl member and the closing of said passageway being accomplishable by lifting said bowl member away from the pool floor.

Claim 5

Stain remover apparatus for swimming pools comprising a bowl member open at its lower end and adapted to be placed in enclosing relation to a pool wall stain, enclosure means associated with said bowl member defining a chamber for a stain remover liquid, a passageway interconnecting said chamber and the interior of said bowl member, and a valve member to open and close said passageway, said valve member comprising a vertically depending stem which normally extends past the lower end of said bowl member, the opening of said passageway being accomplishable by pressing said stem against the pool floor to raise said valve member relative to said bowl member and the closing of said passageway being accomplishable by lifting said bowl member away from the pool floor.

Claim 6

The apparatus of claim 3, said enclosure means being carried by said bowl member, said apparatus further comprising a container for stain remover liquid adapted to be located on the pool deck, and means including a hose connecting said container with said chamber for siphon-action dispensing of stain remover liquid from said apparatus.

Claim 7

The apparatus of claim 4, said apparatus further comprising a weight member attached to said hose by effecting the removal of air from said hose without permitting air blockage by the kinking of said hose.

Claim 8

In combination with pool stain remover apparatus comprising a vented container for stain remover liquid mounted on the deck of a swimming pool, an elongated hose with one end connected to said container and the other end connected to an applicator head at the end of an elongated handle and positioned adjacent the floor of the pool at an elevation lower than the level of said container, a valve located in said head for introducing liquid thereinto from said hose, and a control member to open and close said valve operable by the manipulator of said handle, the method of priming said apparatus for siphon-action dispensing of stain remover liquid to pool wall stains comprising submerging said hose, except for the container to water surface portion of said hose, and said head in a valve-open condition to displace the air from the submerged hose and replace the same with pool water, raising the head in a valve-open condition to a height above the surface of the pool water to displace the air from the container to water surface portion of said hose to said vent connection, re-submerging the previously submerged hose portion with the head in a valve-open condition, thereafter closing said valve, and thereafter opening said valve and displacing the water from said hose with stain remover liquid by causing the stain remover liquid to flow to the bottom of the pool within the applicator head.

Claim 9

In combination with pool stain remover apparatus comprising a vented container for stain remover liquid mounted on the deck of a swimming pool, an elongated hose with one end connected to said container and the other end connected to an applicator head at the end of an elongated handle and positioned adjacent the floor of the pool at an elevation lower than the level of said container, a valve located in said head for introducing liquid thereinto from said hose, and a control member to open and close said valve operable by the manipulator of said handle, the method of priming said apparatus for siphon-action dispensing of stain remover liquid to pool wall stains comprising submerging said hose, except for the container to water surface portion of said hose, and said head in a valve-open condition to displace the air from the submerged hose and replace the same with pool water, raising the head in a valve-open condition to a height above the surface of the pool water to displace the air from the container to water surface portion of said hose to said vent connection, re-submerging the previously submerged hose portion with the head in a valve-open condition, thereafter closing said valve, and thereafter opening said valve and displacing the water from said hose with stain remover liquid by causing the stain remover liquid to flow to the bottom of the pool within the applicator head.
