Abstract
Abstract A sprinkler head apparatus is provided having a casing adapted to be connected to a waterline in which the casing has a tube passing through the top thereof with a nozzle on the end exterior to the casing and a raceway attached to the other end of the tube inside the casing. The raceway is circular and has a ball therein and has a protrusion extending from the top in a manner so that the ball following the raceway will be raised by the centrifugal force and will collide with the protrusion. The ball is pushed by the water entering the water inlet in the side of the casing tangential to the raceway. The water thereafter passes through the tube and out the nozzle. The water pressure in the casing is also adapted to force the tube to slide through the opening in the casing until the raceway becomes level with the water inlet.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
163 words
A sprinkler head apparatus comprising in combination: a. a casing; b. a tubular means having two end portions, rotatably connected to and extending through said casing; c. nozzle means in one end portion of said tubular means and located exterior to said casing; d. raceway means attached to said tubular means and located inside said casing and adapted to rotate with said tubular means; e. ball means located in said raceway means and adapted to move in a circular direction around said raceway; f. said raceway means having upper and lower sections defining a generally circular raceway having an open portion along the periphery of said raceway and said top portion having a protrusion extending into said raceway; and g. water inlet means adapted for water to enter tangential to said raceway to drive said ball means through said raceway, whereby said ball means will be directed against said protrusion to intermittently rotate said raceway means and tubular means of said sprinkler head.
Claim 2
Dependent Claim
163 words
A sprinkler head apparatus comprising in combination: a. a casing; b. a tubular means having two end portions, rotatably connected to and extending through said casing; c. nozzle means in one end portion of said tubular means and located exterior to said casing; d. raceway means attached to said tubular means and located inside said casing and adapted to rotate with said tubular means; e. ball means located in said raceway means and adapted to move in a circular direction around said raceway; f. said raceway means having upper and lower sections defining a generally circular raceway having an open portion along the periphery of said raceway and said top portion having a protrusion extending into said raceway; and g. water inlet means adapted for water to enter tangential to said raceway to drive said ball means through said raceway, whereby said ball means will be directed against said protrusion to intermittently rotate said raceway means and tubular means of said sprinkler head.
Claim 3
Dependent Claim
36 words
The apparatus according to claim 1 in which said raceway bottom portion has flared sides whereby the force of said ball means passing around said raceway means will be lifted to make contact with said protrusion.
Claim 4
Dependent Claim
25 words
The apparatus according to claim 2 in which passageway allows water to pass from said raceway means into said tubular means to said nozzle means.
Claim 5
Dependent Claim
16 words
The apparatus according to claim 3 in which said passageways are openings in said tubular means.
Claim 6
Dependent Claim
44 words
The apparatus according to claim 4 in which said casing is filled with water and pressurized to actuate said tubular means to slide through said opening in said casing until said raceway is level with said water inlet means thereby lifting said nozzle means.
Claim 7
Dependent Claim
22 words
The apparatus according to claim 5 in which said raceway means upper and lower portions are separately connected to said tubular means.
Claim 8
Dependent Claim
49 words
The apparatus according to claim 6 in which said opening in said casing having said tubular means passing therethrough has protrusions for engaging said tubular means whereby water is allowed to flow between said casing and said tubular means during sliding of said tubular means in said casing opening.
