Abstract
Abstract A water sprinkler device comprising a main body housing having a dual pop-up spray nozzle with a cover attached thereto for movement with the spray nozzle, the nozzle being axially aligned within the main body and movably supported in a bearing wall member which is secured intermediate the ends of the main body housing, the spray nozzle being provided with a striking base member for rotating the dual spray nozzles by means of a ball striking the base member. A helical spring is disposed within the base member and a second helical spring is also disposed and secured in the lower portion of the main housing. A valve disc is secured into the lower portion of the main body, said disc having annularly arranged slots and a pair of centrally positioned flow passages which are adjustable for regulating the amount of water passing therethrough by a valve member and a connecting valveadjusting stem.

Independent Claim
82 words
In a sprinkler head, comprising: A. a hollow body, said body having a fluid inlet at the lower end; B. a nozzle operably mounTed at the upper end of said body for rotational movement, said nozzle having an inlet and at least one discharge orifice; C. a flange at the lower end of said nozzle; D. a helical coiled spring covering the nozzle inlet; E. a ball operably disposed within the body; F. and means for swirling fluid introduced into said body.
Claim 2
Dependent Claim
82 words
In a sprinkler head, comprising: A. a hollow body, said body having a fluid inlet at the lower end; B. a nozzle operably mounTed at the upper end of said body for rotational movement, said nozzle having an inlet and at least one discharge orifice; C. a flange at the lower end of said nozzle; D. a helical coiled spring covering the nozzle inlet; E. a ball operably disposed within the body; F. and means for swirling fluid introduced into said body.
Claim 3
Dependent Claim
82 words
In a sprinkler head, comprising: A. a hollow body, said body having a fluid inlet at the lower end; B. a nozzle operably mounTed at the upper end of said body for rotational movement, said nozzle having an inlet and at least one discharge orifice; C. a flange at the lower end of said nozzle; D. a helical coiled spring covering the nozzle inlet; E. a ball operably disposed within the body; F. and means for swirling fluid introduced into said body.
Claim 4
Dependent Claim
82 words
In a sprinkler head, comprising: A. a hollow body, said body having a fluid inlet at the lower end; B. a nozzle operably mounTed at the upper end of said body for rotational movement, said nozzle having an inlet and at least one discharge orifice; C. a flange at the lower end of said nozzle; D. a helical coiled spring covering the nozzle inlet; E. a ball operably disposed within the body; F. and means for swirling fluid introduced into said body.
Claim 5
Dependent Claim
22 words
The invention defined by claim 1, wherein there are a plurality of fluid receiving radial openings at the inlet of the nozzle.
Claim 6
Dependent Claim
30 words
The invention defined by claim 1, wherein the helical coiled spring prevents the ball from lodging in the inlet of the nozzle while permitting water to flow into said nozzle.
Claim 7
Dependent Claim
111 words
In a sprinkler head assembly comprising: A. a hollow body, having a fluid inlet at the lower end thereof; B. a nozzle operably mounted at the upper end of said body for rotational movement therein, said nozzle having an inlet and at least one discharge orifice; C. means at the fluid inlet for the body for swirling fluid introduced into said body; D. a striking means disposed within said body for engaging said nozzle at its lower end, thereby imparting movement to said nozzle; E. and a helical coiled spring disposed at said fluid inlet of said body and arranged to cover said means for swirling fluid introduced into said body.
Claim 8
Dependent Claim
111 words
In a sprinkler head assembly comprising: A. a hollow body, having a fluid inlet at the lower end thereof; B. a nozzle operably mounted at the upper end of said body for rotational movement therein, said nozzle having an inlet and at least one discharge orifice; C. means at the fluid inlet for the body for swirling fluid introduced into said body; D. a striking means disposed within said body for engaging said nozzle at its lower end, thereby imparting movement to said nozzle; E. and a helical coiled spring disposed at said fluid inlet of said body and arranged to cover said means for swirling fluid introduced into said body.
Claim 9
Dependent Claim
62 words
In a sprinkler head, as recited in claim 4, wherein said means for swirling fluid comprises a disc having plurality of annularly arranged inclined slots for passage of said fluid therethrough in a swirling upward motion, activating said striking means; and at least one vertical opening arranged in parallel relation with the axis of said body whereby fluid can flow directly upward.
Claim 10
Dependent Claim
28 words
The invention defined by claim 5, including a valve plate movably secured to said disc, said valve plate positioned to control said fluid flow through said vertical opening.
Claim 11
Dependent Claim

The invention defined by claim 1, including a second helical coiled spring disposed in said fluid inlet of said body to protect the means for swirling fluid introduced into said body.
Claim 12
Dependent Claim
29 words
The invention defined by claim 7, including adjusting means within the sprinkler head for regulating the flow of fluid through the means for swirling fluid introduced into said body.
Claim 13
Dependent Claim
186 words
In a sprinkler head assembly comprising: a hollow body, having a fluid inlet at the lower end thereof; a nozzle operably mounted at the upper end of said body for rotational movements therein, said nozzle having an inlet and at least one discharge orifice; a striking means disposed within said body for engaging said nozzle at its lower end, thereby imparting movement to said nozzle; means for swirling fluid introduced into said body, said means including a disc having a plurality of annularly arranged, inclined slots for fluid flow therethrough in a swirling, upward motion for activating said striking means; and a valve plate movably secured to said disc, said valve plate positioned to control said fluid for swirling fluid introduced into said body; and adjusting means for adjusting the means for swirling fluid introduced into said body, said adjusting means including an actuator operably within the hollow body having an internal vertical channel therein and a rod adapted to be disposed in said channel for engagement with said valve plate to adjust said plate for varying fluid flow through the inclined slots of said disc.
