Abstract
A sprinkler comprising a body, a passage having an inlet and an outlet end through the body, means associated with the inlet end for connecting it to a supply source of water and a distribution cap located over the outlet end, the cap having a skirt extending away from the body, a closed end remote from the body and a series of outlet perforations through the wall of the cap, the series extending at least partway around the periphery of the cap.
Claims (11)
1. A sprinkler, comprising: a body; means defining a passage through the body and having an inlet end and an outlet end; means associated with the inlet end for connecting the passage to a water supply source; a separate distribution cap snap fit on the sprinkler and extending over the outlet end of the passage, so that water issuing therefrom impinges thereon; means defining a series of outlet perforations through the cap, about at least part of the outer periphery thereof, so that water which has impinged on the cap may pass out through the perforations; the cap, where the water impinges thereon having an at least part-concial surface with the apex thereof directed towards the outlet end of the passage; the longitudinal axis of the conical surface being at least roughly coincident with the longitudinal axis of the outlet end.
2. A sprinkler as claimed in claim 1 in which the sprinkler is made of moulded plastics material.
3. A sprinkler as claimed in claim 1 in which the outlet from the passage is constricted to the desired size for flow therethrough.
4. A sprinkler as claimed in claim 1 in which the cap, once in position on the body is rotatable relative thereto.
5. A sprinkler as claimed in claim 1 in which the perforations are located on a circumference of the cap remote from the body.
6. A sprinkler as claimed in claim 1 in which the perforations are defined by an external step decrease in diameter of the caP combined with a riffling or serrating of the inner surface of the closed end of the cap at least adjacent the periphery of said closed end, the riffles or serrations thereby defining troughs and peaks, the troughs of the serrations or riffles defining the perforations and the peaks of the serrations or riffles connecting the said end to the skirt.
7. A sprinkler as claimed in claim 1 in which the means for connecting the body to a supply source of water comprises a spigot carrying external screw threads.
8. A sprinkler as claimed in claim 7 in which the screw threads taper down to a smooth external wall adjacent the free end of the spigot.
9. A sprinkler as claimed in claim 7 in which the free end of the spigot is inclined to the axis thereof.
10. A sprinkler as claimed in claim 7 in which the body is provided with formations engageable by means of a spanner.
11. An irrigation sprinkler, comprising: a one-piece moulded plastic body having means defining a longitudinal passageway therethrough; a non-circular enlargement formed on the body intermediate the ends thereof for receipt of a tool for angularly turning the body; said body, extending below the enlargement being exteriorly threaded and terminating in a downwardly directed point, whereby the body may be stabbed into a flexible water pipe and turned with a tool to engage the threads in the material of the pipe; the body further including means defining a circumferentially extending, outer peripheral groove therein above said enlargement; and a distribution cap, having an interiorly generally conical upper end wall and a depending peripheral skirt; the skirt having a circumferential flange near the lower end thereof, which is snapped into said groove to fasten the cap onto the body so that the upper end wall of the cap lies spaced above where the longitudinal passageway emerges upwardly from the body; means defining a plurality of angularly spaced outlets from the cap adjacent the outer periphery of the upper end wall thereof; and means defining a radiating array of serrations on the interiorly generally conical upper end wall, the serrations leading to the outlets from where irregating liquid issuing upwardly from longitudinal passageway impinges on said upper end wall.
