Sprinkler system

An adjustable arc sprinkler mechanism comprising:

• a sprinkler housing having a rotating portion, a stationary portion and an arc adjustment mechanism;
• said rotating portion including a first set of pear teeth;
• said arc adjustment mechanism including a second set of gear teeth selectively engagable with said first set of gear teeth;
• said arc adjustment mechanism including an arc stop selectively angularly movable relative to said rotating portion and said stationary portion so as to set a desired arc for said rotating portion of said sprinkler mechanism;
• said arc stop being movable between a minimum arc setting and a full circle setting;
• said arc stop being movable between said minimum arc setting and said full circle setting without changing a vertical height of said sprinkler mechanism.

A method of establishing full circle operation of an adjustable arc sprinkler mechanism comprising:

• providing a sprinkler having a rotating section, a stationary section and an arc adjustment section, wherein said sprinkler has an established sprinkler height;
• disengaging said arc adjustment section from said rotating section without changing the overall height of said adjustable arc sprinkler mechanism by decoupling a geared engagement between said arc adjustment section and said rotating section;
• moving said arc adjustment section to a full circle setting on said sprinkler;
• maintaining said established sprinkler height during both the disengaging of said arc adjustment section and during the moving of said arc adjustment section to said full circle setting.

An adjustable arc sprinkler mechanism comprising:

• an upper rotatable sprinkler housing;
• a lower stationary sprinkler housing;
• an arc stop assembly interposed between said upper and lower sprinkler housing;
• said arc stop assembly including a fixed arc stop member and an angularly movable arc stop member;
• and,
• wherein at least one position of said angularly movable arc stop member enables said rotatable sprinkler housing to rotate in one continuous direction, and said angularly movable arc stop member is movable according to disengagement of said arc stop assembly from said upper rotatable sprinkler housing.

An adjustable arc sprinkler mechanism comprising:

• an upper rotatable sprinkler housing;
• a lower stationary sprinkler housing;
• an arc stop assembly interposed between said upper and lower sprinkler housing;
• said arc stop assembly including a fixed arc stop member disposed on said upper rotatable sprinkler housing and an angularly movable arc stop member, said fixed arc stop member including a radially flexible stop surface, said stop surface being radially flexed out of engagement with a sprinkler stop when said arc stop is at a full circle setting;
• and,
• wherein at least one position of said angularly movable arc stop member enables said rotatable sprinkler housing to rotate in one continuous direction.

An adjustable arc sprinkler mechanism comprising:

• a sprinkler housing having a rotating portion, a stationary portion and an arc adjustment mechanism;
• said arc adjustment mechanism including an arc stop selectively angularly movable relative to said rotating portion and said stationary portion so as to set a desired arc for said rotating portion of said sprinkler mechanism;
• said arc stop being movable between a minimum arc setting and a full circle setting;
• said arc stop being movable between said minimum arc setting and said full circle setting without changing a vertical height of said sprinkler mechanism;
• and
• wherein said arc stop is movable according to disengagement of an arc stop assembly from said rotatable portion.

An adjustable arc sprinkler mechanism comprising:

• a sprinkler housing having a rotating portion, a stationary portion and an arc adjustment mechanism;
• said arc adjustment mechanism including an arc stop selectively angularly movable relative to said rotating portion and said stationary portion so as to set a desired arc for said rotating portion of said sprinkler mechanism;
• said arc stop being movable between a minimum arc setting and a full circle setting;
• said arc stop being movable between said minimum arc setting and said full circle selling without changing a vertical height of said sprinkler mechanism;
• said arc adjustment mechanism further including a fixed arc stop member disposed on said rotating portion, wherein said fixed arc stop member includes a radially flexible stop surface, said stop surface being radially flexed out of engagement with a sprinkler stop when said arc stop is at said full circle setting.

A method of establishing full circle operation of an adjustable arc sprinkler mechanism comprising:

• providing a sprinkler having a rotating section, a stationary section and an arc adjustment section, wherein said sprinkler has an established sprinkler height and wherein said arc adjustment section includes an arc stop;
• disengaging said arc adjustment section from said rotating section without changing the overall height of said adjustable arc sprinkler mechanism;
• moving said arc stop of said adjustment section to a full circle setting on said sprinkler;
• and
• maintaining said established sprinkler height during both the disengaging of said arc adjustment section and during the moving of said arc stop of said adjustment section to said full circle setting.

A method of establishing full circle operation of an adjustable arc sprinkler mechanism comprising:

• providing a sprinkler having a rotating section, a stationary section and an arc adjustment section, wherein said sprinkler has an established sprinkler height and wherein said arc adjustment section further includes a fixed arc stop member disposed on said arc adjustment section, wherein said fixed arc stop member includes a radially flexible stop surface;
• disengaging said arc adjustment section from said stationary section without changing the overall height of said adjustable arc sprinkler mechanism;
• moving said arc adjustment section to a full circle selling on said sprinkler;
• maintaining said established sprinkler height during both the disengaging of said arc adjustment section and during the moving of said arc adjustment section to said full circle setting;
• and
• urging said radially flexible stop surface out of engagement with a trip arm when said arc adjustment section is at said full circle setting.
