y invention relates to Water distribution and more particularly to an automatic sprinkler of the rotary type. The invention pertains,to a rotary sprinkler having pivoted or folding jet arms carried by asprinkler head provided-with a discharge nozzle rotating in unison with said arms the structure being of operative position by variations of the water supply pressure, the sprinkler head being retractible into a sunken receiver or container within which the sprinkler is con-l cealed when not in use. The construction is such that upon the admission of water under pressure to the sprinkler the latter is bodily elevated out of its sunken receptacle or container the jet larms being simultaneously ac tuated to the extended positions, whereafter the influence of .the discharging jets of water may serve to rotate the sprinkler head -pressure is reduced the. sprinkler settles by gravity into its receptaclethe jet-armsfbeing projected to an upright or substantially vertical position by their engagement upon the rim of the'receiver or receptacle and the latter .is closed by a lid supported upon the I sprinkler head.

CIG

'The Object of the invention is'to simplify the structure as well as the means and mode of operation of such automatic sprinklers, whereby they will not only be 'cheapened in construction, but will be more efficient in use,

positive in operation, uniform in action, easily controlled andunlikelyto get out of re- P311' A further object of the invention is toprovide improved means for mounting the adjustable propeller arms or jet arms for such sprinkler head.

A further object of the i invention is to provide an improved. mountingv `for the sprinkler head, whereby it maybe easilyY ac.- tuated to and from operative position under the influence of fluid pressure control.l I A further object of the invention'is to provide improved rotary bearings for the -revolving sprinkler, and to provide an 1mproved method of mounting the rotary sprinkler head-within its bearing whereby the wear will be minimized andthe durability ofthe sprinklerfhead and its bearing ver'ticallymovable into and out peller arms.

That is to say, the discharge of the jet orifices 17 -will initially propel the pivoted arms 16 jet arms outwardthe extremities thereof. v

In addition to the jet oriiices 17 the ropeller arms may be provided' with additional orifices in the extreme endsthereof. To limit the movement of these propeller arms 16 to 'and fi'om operative engagement there are 'provided sli'ort stop arms 18, projecting. into the plane of oscillation of the arms'16 and limiting the arms in approximately upright position and other arms 19 downturned over the sides 13 with theirextremities of the cap' or head to form rests forv the vprojected outwardly arms 16. Stop arms and outwardly projectingrest arms 19 are preferably stamped from a single piece of sheet metal and secured to the top`of vthe distributor -head or cap byother suitable means. However, any

In Fig. 7 there is shown a modification ofthis con- 4struction'wherein the trunnion stud is stationary and the head of the propeller arm oscillates thereabout. In this construction the heads 25 of the propeller arms 16 are counterbored to form a seat or shoulder 26 at their inner `ends with which engages the head of the hollow trunnion stud l27. This trunnion stud 27 is screw threaded into openings in the side of the upper fend of the revoluble hollow trunnion 12. In this case the trunnion 12 is closed at its upper end and the propeller arms are connected directly to the trunnion in lieu of the head or cap 15. The outer ends of the propeller arms 25 are .closed by removablel -closure plugs or caps 28,'the removal of which af-- fords access to the trunnion stud 27.
