Abstract
Abstract A sprinkler or lawn spray of the reaction type has a flexible shield cooperating with a guide channel to direct the water emerging from the jet of the spray body in the desired direction and dispersal pattern. The shield may be of a flexible material or may be flexibly mounted to either the reaction arm or the spray body to preclude droplet distribution in a direction normal to the emerging stream from the spray jet. The shield is mounted either to the reaction arm or to the oscillating body of the spray. The stream guide channel may be open or closed and has an emerging reaction surface against which the jet stream impinges.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
138 words
In a reaction sprinkler having a spray body with a water spray jet and a springloaded reaction arm moving responsive to the water from the jet to impact the body to rotate said body and jet, the combination comprising a water guide channel with entry and discharge ports and secured to the sprinkler reaction arm; said channel having one guide wall at an angle to the water path from the jet and another guide wall at an angle to the first wall; a reaction surface at the discharge end of the guide channel at an angle thereto in the path of the water stream; a flexible shield secured to the sprinkler adjacent the discharge port of the guide channel, said shield being resiliently flexible in a direction normal to the path of the stream from the spray jet.
Claim 2
Dependent Claim
138 words
In a reaction sprinkler having a spray body with a water spray jet and a springloaded reaction arm moving responsive to the water from the jet to impact the body to rotate said body and jet, the combination comprising a water guide channel with entry and discharge ports and secured to the sprinkler reaction arm; said channel having one guide wall at an angle to the water path from the jet and another guide wall at an angle to the first wall; a reaction surface at the discharge end of the guide channel at an angle thereto in the path of the water stream; a flexible shield secured to the sprinkler adjacent the discharge port of the guide channel, said shield being resiliently flexible in a direction normal to the path of the stream from the spray jet.
Claim 3
Dependent Claim
16 words

Claim 4
Dependent Claim
16 words
A sprinkler in accordance with claim 1 wherein the shield is secured to the reaction arm.
Claim 5
Dependent Claim
36 words
A sprinkler in accordance with claim 1 wherein the shield comprises a sheet, and flexible means securing the sheet to the sprinkler to flex resiliently therefrom away from and toward the path of the water stream.
Claim 6
Dependent Claim
30 words
A sprinkler in accordance with claim 4 wherein the flexible means comprises a pair of threaded fasteners engaged in the sprinkler, an spring means biasing the sheet toward the sprinkler.
Claim 7
Dependent Claim
36 words
A sprinkler in accordance with claim 4 further comprising second and third sheets, and spacers between the adjacent sheets, said second and third sheets differing in peripheral configuration from the first sheet and from each other.
Claim 8
Dependent Claim
20 words
A sprinkler in accordance with claim 1 wherein the shield comprises a resiliently flexible sheet secured to the spray body.
Claim 9
Dependent Claim
19 words

Claim 10
Dependent Claim
46 words
A sprinkler in accordance with claim 1 wherein the shield further comprises a first section secured to the reaction arm, a second section extending from the first at an obtuse angle thereto and a third reaction surface extending from the second section at an angle thereto.
Claim 11
Dependent Claim
111 words
A shield to prevent random spray from a sprinkle of the reaction type having a spray body with a water spray jet and a springloaded reaction arm moving responsive to the water impact from the water jet to in turn impact the spray body to rotate said body and jet, said reaction arm having a guide section intercepting the water stream from the jet with each rotational impulse, said shield comprising a shaped sheet secured to the sprinkler adjacent the water jet and extending from the sprinkler downstream from the water jet and to one side thereof, said sheet being resiliently flexible with respect to the path of the water jet.
Claim 12
Dependent Claim
111 words
A shield to prevent random spray from a sprinkle of the reaction type having a spray body with a water spray jet and a springloaded reaction arm moving responsive to the water impact from the water jet to in turn impact the spray body to rotate said body and jet, said reaction arm having a guide section intercepting the water stream from the jet with each rotational impulse, said shield comprising a shaped sheet secured to the sprinkler adjacent the water jet and extending from the sprinkler downstream from the water jet and to one side thereof, said sheet being resiliently flexible with respect to the path of the water jet.
Claim 13
Dependent Claim
29 words
A shield in accordance with claim 10 secured to the reaction arm, and further comprising a reaction surface at an angle to the sheet and the water stream path.
Claim 14
Dependent Claim
19 words
A shield in accordance with claim 11 wherein the angle to the sheet is between five and fifty degrees.
Claim 15
Dependent Claim
36 words
A shield in accordance with claim 10 wherein the shield comprises a sheet, and resiliently flexible means securing the sheet to the sprinkler to flex therefrom away from and toward the path of the water stream.
Claim 16
Dependent Claim
31 words
A shield in accordance with claim 13 wherein the flexible means comprises a pair of threaded fasteners engaged in the sprinkler, and spring biasing means loading the sheet toward the sprinkler.
Claim 17
Dependent Claim
36 words
A shield in accordance with claim 13 further comprising second and third sheets, and spacers between the adjacent sheets, said second and third sheets differing in peripheral configuration from the first sheet and from each other.
Claim 18
Dependent Claim
