In taking up the description; f the Asti-ue tural features of my invention I will first here particular reference to Fig. l in which one of my sprinkling units is'most clearly shown as en entirely. A

The numeral 1 designates a. water mein-of4 the usual construction located some distance below the surface of the street and provided l with the three way union 2 in the upper part of which is positioned the supply pipe 3. The mein portion of mysprinkling devioe comprises `e tired pipe 4 and a' movable pipe 5 adapted for longitudinal displacement' -within seid pipe 4. -A suitable sleeve pipe 6 internally screw threaded-as at-T'upon each extremity for portion of the`length thereof is threaded upon the lower extremity of the xed pipe 4 und' the upper er:-A tremity of the supply pipe 3 in suoli meu ner that u water tight jointis" formed.

The sliduble inner pipe is internally screw threaded as e118 for the portion-odjacent its upper extremity and externally screw threaded as shown at 9 upon its lower` sev extremity. Theinternelly screw threaded ring 1f) is threeded upoirthis lower entr-einity of the pipe 4 and is adapted to-be ernbraced by the-sleeve 6 in slidable relation` thereto, On the upper face of this ring 1.0 I provide an opstanding inverted V-shnped ex'tension 11 which is formed integrally .therewith and which is adapted to engage in a correspondingly shaped notch 12 which is formed in the lower edge of theliixcd pipe s, said notch and seid extension serving the purpose to be hereinafter clearly hro'uoht out.
