Abstract
An adjustable orifice sprinkler unit includes a tubular body member with a rotatable cap mounted on one end thereof that cooperates with peripheral edges of the tubular body member for defining an adjustable arc spray orifice for adjusting a spray pattern from an angle of from about 0 degrees up to about 360 degrees with the cap adjustable axially of the tubular body member for selectively adjusting the height of the orifice opening.
Claims18
An adjustable orifice sprinkler unit, comprising:
- a tubular body member having an inlet means for attachment to a source of pressurized water and an outlet end surrounded by a first circular peripheral edge having axially offset ends;
- and
- a rotatable member mounted on said outlet end of said tubular body member and including means defining a second circular peripheral edge having axially offset ends, and positioned coaxially adjacent to and cooperating with said first circular peripheral edge for defining an adjustable width arcuate outlet orifice that is adjustable in width upon rotation of said rotatable member relative to said tubular body member.
An adjustable orifice sprinkler unit, comprising:
- a tubular body member having an inlet means for attachment to a source of pressurized water and an outlet end surrounded by a first circular peripheral edge having an axially stepped portion;
- a rotatable member mounted coaxial of and on said outlet end of said tubular body member and including an axially extending skirt defining a second circular peripheral edge having an axially stepped portion for at least partially overlapping and cooperating with said first circular peripheral edge for defining an adjustable width arcuate outlet orifice that is adjustable in width upon rotation of said rotatable member relative to said tubular body member;
- and
- wherein said first circular peripheral edge and said second circular peripheral edge each spiral axially and each have an offset end connected by a vertical edge defining said axially stepped portion.

An adjustable orifice sprinkler unit, comprising:
- a tubular body member having an inlet means for attachment to a source of pressurized water and an outlet end surrounded by a first continuous circular peripheral edge having an axially stepped portion;
- a rotatable member mounted on said outlet end of said tubular body member and including means defining a second circular peripheral edge having an axially stepped portion positioned coaxially adjacent to and cooperating with said first circular peripheral edge for defining an adjustable width arcuate outlet orifice that is adjustable in width upon rotation of said rotatable member relative to said tubular body member;
- and
- wherein the outlet orifice is adjustable from about 0 degrees to about 360 degrees about the axis of said tubular body member.

An adjustable orifice sprinkler unit, comprising:
- fixed housing means defining a passage having an inlet for attachment to a source of pressurized water and an outlet defined by a first circular edge having axially offset ends for dispensing water;
- and
- moveable housing means mounted on said fixed housing means and including means defining a second circular edge having axailly offset ends cooperative with said first circular edge of said fixed housing means for defining an adjustable angle dispensing orifice adjustable about the axis of said outlet.
An adjustable orifice sprinkler apparatus, comprising:
- a tubular member having an inlet end and an outlet end and a passage communicating therebetween, said outlet end defined by a spiral edge having offset ends connected by a generally straight edge;
- a cap member rotatably mounted on the outlet end of said tubular member and having a tubular skirt coaxial of said tubular member, said skirt terminating in a spiral edge having offset ends connected by a generally straight edge;
- and,
- screw means for rotatably mounting said cap member coaxially of said tubular member, with said spiral edges and said straight edges in opposed cooperative relationship for defining a variable width and variable height orifice, said cap member being rotatable for varying said orifice from about zero to about three hundred and sixty degrees, and said cap member being moveable axially of said tubular member by rotation of said screw member for varying the height of said orifice.
