Sprinkler device

Claim 2

A sprinkler device for discharging water over a selected arcuate sector of a selected radius through external adjustment, comprising: a housing having a water inlet, a sprinkler head having a water outlet in fluid communication with said housing inlet, means in said housing for rotatably mounting said sprinkler head, water turbine means in said housing operable by water admitted through said inlet for rotating said sprinkler head, and means for reversing the direction of rotation of said sprinkler head including overcenter actuating means responsive to the arcuate position of said means for rotatably mounting the sprinkler head, and reversing gear means including a movably mounted gear in operative engagement with said overcenter actuating means so as to rotate said sprinkler head in opposite directions.

Claim 3

The sprinkler device of claim 1 wherein said movably mounted gear is supported adjacent one end of a pivot plate, and said means for reversing the direction of rotation of said sprinkler head additionally includes means interconnecting said overcenter actuating means and the opposite end of said pivot plate, whereby movement of said overcenter actuating means moves said pivot plate into one of two positions so that said movable gears engages one of the two counterrotating gear units so as to rotate the sprinkler head in opposite directions.

Claim 4

The sprinkler device of claim 2 wherein said reversing gear means additionally includes gear reduction means, said reversing gear means and gear reduction means and said overcenter actuating means being sealingly enclosed in an inner housing to prevent contamination thereof by the water flowing through said sprinkler device when in operation.

Claim 5

The sprinkler device of claim 3 additionally including means for diverting a portion of the water admitted through said water inlet so as to bypass said water turbine means thereby allowing the water to pass directly to the sprinkler head water outlet.

Claim 6

A sprinkler device for discharging water over a selected arcuate sector of a selected radius through external adjustment, comprising: a housing having a water inlet, a sprinkler head having a water outlet in fluid communication with said housing inlet, means in said housing for rotatably mounting said sprinkler head, water turbine means in said housing operable by water admitted through said inlet for rotating said sprinkler head, means for reversing the direction of rotation of said sprinkler head including reversing gear means responsive to the arcuate position of said means for rotatably mounting said sprinkler head; and means for externally adjusting the arcuate movement of said means for rotatably mounting said sprinkler heaD so as to vary the arc of rotation of said sprinkler head between reversals thereof while said sprinkler device is in operation.

Claim 7

A sprinkler device for discharging water over a selected arcuate sector of a selected radius through external adjustment, comprising: a housing having a water inlet, a sprinkler head having a water outlet in fluid communication with said housing inlet, means in said housing for rotatably mounting said sprinkler head, water turbine means in said housing operable by water admitted through said inlet for rotating said sprinkler head, means for reversing the direction of rotation of said sprinkler head including reversing gear means responsive to the arcuate position of said means for rotatably mounting said sprinkler head; and means for externally adjusting the arcuate movement of said means for rotatably mounting said sprinkler heaD so as to vary the arc of rotation of said sprinkler head between reversals thereof while said sprinkler device is in operation.

Claim 8

The sprinkler device of claim 5 wherein said means for adjusting the arcuate movement of said means for rotatably mounting said sprinkler head comprises, gear means rotatably mounted on said means for rotatably mounting said sprinkler head and carrying a pin radially spaced from the axis of said sprinkler device, pinion drive gear means carried by said sprinkler head and axially slidably disposed in said means for rotatably mounting said sprinkler head and engaging said gear means, means for rotating said pinion gear externally from said housing, whereby said pin supported by said gear means may be selectively arcuately positioned to adjust the arc of rotation of said sprinkler head.

Claim 9

The sprinkler device of claim 6 wherein said sprinkler head includes means for arcuately adjusting said sprinkler head relative to said means for rotatably mounting said head.

Claim 10

The sprinkler device of claim 7 wherein said housing carries means for externally selectively adjusting the rate of waterflow through the sprinkler device, whereby the radius of the arcuate sector over which water is discharged through the sprinkler head is selected.

Claim 11

A popup-type sprinkler device for discharging water over an arcuate sector of externally selected width, radius and position, comprising: a housing having a water inlet, a sprinkler head having a water outlet in fluid communication with said housing inlet, a shaft in said housing for mounting said sprinkler head for rotatable and axially slidable movement, water turbine means in said housing, rotatable by water admitted through said inlet for rotating said sprinkler head and carrying a turbine pinion gear, a pair of gear units comprising coaxially secured pinions and spur gears, one of said spur gears engaging said turbine pinion gear and engaging the other spur gears so that said gear unit pinion gears counterrotate, a movable gear mounted on a pivot plate and engaging one of said counterrotating pinion gears, a spur gear mounted on said shaft and engaging said movable gear through a gear reduction train, an overcenter actuating means for moving said pivot plate in response to the arcuate position of said sprinkler head shaft, means for selectively, externally adjusting the limits of arcuate movement of said sprinkler head shaft so as to select the width of the arcuate sector through which the sprinkler head oscillates, means for selectively, externally adjusting the rate of waterflow through said sprinkler so as to select a sector radius, and means for selectively, externally adjusting the position of said sprinkler head on said mounting shaft so as to arcuately position the arcuate sector over which water is discharged.

Claim 12

A popup-type sprinkler device for discharging water over an arcuate sector of externally selected width, radius and position, comprising: a housing having a water inlet, a sprinkler head having a water outlet in fluid communication with said housing inlet, a shaft in said housing for mounting said sprinkler head for rotatable and axially slidable movement, water turbine means in said housing, rotatable by water admitted through said inlet for rotating said sprinkler head and carrying a turbine pinion gear, a pair of gear units comprising coaxially secured pinions and spur gears, one of said spur gears engaging said turbine pinion gear and engaging the other spur gears so that said gear unit pinion gears counterrotate, a movable gear mounted on a pivot plate and engaging one of said counterrotating pinion gears, a spur gear mounted on said shaft and engaging said movable gear through a gear reduction train, an overcenter actuating means for moving said pivot plate in response to the arcuate position of said sprinkler head shaft, means for selectively, externally adjusting the limits of arcuate movement of said sprinkler head shaft so as to select the width of the arcuate sector through which the sprinkler head oscillates, means for selectively, externally adjusting the rate of waterflow through said sprinkler so as to select a sector radius, and means for selectively, externally adjusting the position of said sprinkler head on said mounting shaft so as to arcuately position the arcuate sector over which water is discharged.
