Carlson, Jacksonville, Fla. Application June 23, 1944, Serial No. 541,796 ` z anims. (C1. 299-67) ` ` 1 2 This invention relates to sprinkler heads especially designed for use with underground lawn sprinkling systems, and' it consists in the constructions, arrangements and combinations vertically and axially' of the head I5 but stoppin short ofthe upper open end of the sprinkler body I3. Inwardly of the upper end of the stud I8 a longitudinal reduced portion I9 is formed, pro herein described and claimed. It is a particular object »of the invention to ' f 5 viding a shoulder I9’ and a head 20. > A bell-shaped rotor or turbine 2| is employed, ' provide a sprinkler constructed in such manner formed of rubber or other suitable material, the that there is little danger of injuries to persons reduced portion 22 thereof having an axial bore or damage to the sprinkler head or a lawn mower 23 within which a iianged Sleeve 24 is embedded, when the latter is moved across a lawn equipped 10 the sleeve being of a length terminating slightly with my sprinkler devices.

Upon the interior Y It is a still further and important object of ' ,of the sleeve an annular groove 25 is formed,y the invention to provide a sprinkler of the charadapted to receive a split rmg 2li.r `The ring 26 acter indicated in which a rotor is employed, 7 normally rests upon the shoulder |9’ of the stud actuated by the out-flow of Water, effecting a r1_5 |3,as shown in Figure 5„_leaving ample clearance more uniform distribution of water. , ' ` for vertical movement of the rotorv2| to afford It is also an object of the invention to provide a sprinkler head in which the rotor mem- passage of water between the rotor and the body I3. To assemble the rotor upon the stud, the split ~ ber' is longitudinauy movable to an unseated ring 26 being held compressed about the reduced position with respect to the head proper during 20 DOrti0n,’tl1e Stud and Spring are presented into operation and movable under action of gravity to the sleeve 24 and moved longitudinally therein a seated position to a horizontal point below the ‘ level ordinarily traversed 'by the cutting reel of a lawn mower. until the Spring eXpendS into the grOOVe 25 0f the rotor. ` The rotor 2| is formed with a plurality of lon Additional objects, advantages and features oi ,25 gitudinally extending VaneS 2l upOnfthe Outerl invention will be apparent from the- following de- periphery thei'eOf, the VaneS being 0f a length scription considered in conjunction with the ac- ' extending from a point adjacent the reduced end companying drawing, wherein ofthe rotor to a point slightly below the open Figure lisafragmentary vertical sectional view end I4 of the body I3, when the rotor is of the sprinkler constructed in accordance with 30 seated engagement.
