Abstract
Abstract A lawn sprinkler comprised of only an elongated, tubular body threaded on at least one end thereof for connection to a hose, a ground engaging support means on said body, and a flexible discharge tube removably attached to an outlet fitting on the top of the tubular body. The flow of pressurized water through the discharge tube, preferably an 8 to 10 inch length of rubber tubing, causes the flexible discharge tube to rapidly rotate through an arcuate path to thereby distribute water in an even pattern.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
153 words
A lawn sprinkler comprising; an elongate, tubular body threaded at one end thereof for removable attachment to a garden hose; a length of flexible discharge tube connected to the top side of said body and extending upwardly therefrom, said discharge tube being in fluid flow communication with the interior of said body by means of a discharge passage in said top side of said body, the flow of pressurized water through said flexible tube causing said tube to be held substantially upright and to rotate through an arcuate path to thereby distribute water evenly in a substantially circular area; a plurality of longitudinal slits in the outer end of said discharge tube, said slits defining therebetween a plurality of elongated, flexible leaf sections which spread apart under the influence of water pressure to permit water droplets to be formed and discharged therebetween; and ground engaging means depending from the underside of said body.
Claim 2
Dependent Claim
153 words
A lawn sprinkler comprising; an elongate, tubular body threaded at one end thereof for removable attachment to a garden hose; a length of flexible discharge tube connected to the top side of said body and extending upwardly therefrom, said discharge tube being in fluid flow communication with the interior of said body by means of a discharge passage in said top side of said body, the flow of pressurized water through said flexible tube causing said tube to be held substantially upright and to rotate through an arcuate path to thereby distribute water evenly in a substantially circular area; a plurality of longitudinal slits in the outer end of said discharge tube, said slits defining therebetween a plurality of elongated, flexible leaf sections which spread apart under the influence of water pressure to permit water droplets to be formed and discharged therebetween; and ground engaging means depending from the underside of said body.
Claim 3
Dependent Claim
21 words
A laWn sprinkler as defined in claim 1 wherein: said ground engaging means comprises an elongated stake depending from said body.
Claim 4
Dependent Claim
50 words
A lawn sprinkler as defined in claim 2 wherein: said ground engaging means includes a support stem depending from the underside of said body and formed integrally therewith, said stem having a recess extending lengthwise thereof in which said ground engaging stake is slidably received in a force fit therewith.
Claim 5
Dependent Claim
61 words
A lawn sprinkler as defined in claim 1 wherein: said flexible discharge tube is connected to the top side of said tubular body by means of an upwardly extending discharge fitting formed integrally with said body and communicating at its inner end with said discharge passage, said flexible discharge tube being snugly fitted over said fitting in tight, sealing engagement therewith.
Claim 6
Dependent Claim
97 words
A lawn sprinkler as defined in claim 1 wherein: said flexible discharge tube is made of resilient material and is connected to said tubular body by being force fitted over an upwardly extending discharge nipple communicating at its inner end with said discharge passage in said top side of said tubular body, said tubular body and discharge nipple being of unitary, plastic molded construction; and said ground engaging means comprises a hollow stem depending downwardly from said tubular body and molded integrally therewith, and a ground engaging stake removably inserted and tightly held within said hollow stem.
Claim 7
Dependent Claim
52 words
A lawn sprinkler as defined in claim 1 wherein: said one end of said tubular body is provided with female threads, and the opposite end of said body is open and has male threads, thereon, whereby a plurality of said sprinklers may be connected in series by lengths of hose extending therebetween.
Claim 8
Dependent Claim
49 words
A lawn sprinkler as defined in claim 6, and further including: a threaded cap removably secured to said opposite end of said tubular body by means of said male threads thereon, thereby closing said open, opposite end of said body when no additional length of hose is connected thereto.
Claim 9
Dependent Claim
141 words
A sprinkler device comprising: a rigid, hollow, water receiving body having coupling means at one end thereof for removable attachment to a water conduit; a length of flexible discharge tube connected to one side of said body and extending outwardly therefrom, said discharge tube being in fluid flow communication with the interior of said hollow body by means of a discharge passage in said one side of said body, the flow of pressurized water through said flexible tube causing said tube to rotate through an arcuate path to thereby distribute water evenly in a substantially circular area; and a plurality of longitudinal slits in the outer end of said discharge tube, said slits defining therebetween a plurality of elongated, flexible leaf sections which spread apart under the influence of water pressure to permit water droplets to be formed and discharged therebetween.
Claim 10
Dependent Claim
141 words
A sprinkler device comprising: a rigid, hollow, water receiving body having coupling means at one end thereof for removable attachment to a water conduit; a length of flexible discharge tube connected to one side of said body and extending outwardly therefrom, said discharge tube being in fluid flow communication with the interior of said hollow body by means of a discharge passage in said one side of said body, the flow of pressurized water through said flexible tube causing said tube to rotate through an arcuate path to thereby distribute water evenly in a substantially circular area; and a plurality of longitudinal slits in the outer end of said discharge tube, said slits defining therebetween a plurality of elongated, flexible leaf sections which spread apart under the influence of water pressure to permit water droplets to be formed and discharged therebetween.
