NELSON, OF TROY, OHIO, .ASSGNORS TO TFHEVSKIYNNER IRRIGATION COMPANY,AOF TROY, OHIO, AFCORPORATION OFOHIO sPRINKLnR Application ledAprl 25,

i vision of a sprinkler having a supporting housing portion extending substantially to the top of thesprinkler and within which the sprinkler member is normally retracted, the top of the supporting housing being a separate housing piece detachably connected to the top of the supporting housing portion by means accessible at the topof the sprinkler.

VOther objects and advantages of the invention will be apparent from the following dee scription, the appended claims, and the accompanying drawing, which discloses two embodiments of the invention, and in which Fig. 1 is a vertical section through a sprinkler embodying the present invention; Fig. 2 is a. horizontal section on the line 2 2 of Fig. 1; Y

Fig.v 3 is av section on the line and i Y Fig. l is a vertical section through a 3-3 of Fig. 2;

f sprinkler showing a modified form of construction.

In the drawing, in which like characters of reference designate like parts in the various views, and referring first to Figs. 1 to 3 inclusive, the sprinkler herein shown is of the pop-up type in which the sprinkling member is adapted to be raisedto an extended operating position when in operation. Vhen not operating the sprinkling member is housed substantially flush with the top of a housing, designated generally 10, which "is buried in the ground so that its top is substantially Hush with the ground level. The sprinkling member designated generally 11 comprises a sprinkling cap 12 which seats in a depression 1930. sereni1ra-447,347.

13 in the. housing when the sprinkler is not 1n operation. Below this cap `12 are any suitable number of sprinkling nozzles 14 whichr vare in communication with the water 'passage `15 provided'in thesprinlrling member.

f Y The sprinkling member embodies aV tubular Y portion 16 which is rotatably mounted and supported by a bearing portion 17 provided 1n the housing 'top piece 18. A socket 19 in this top piece provides a recess in which'the operating parts of the sprinkling member may be retracted and enclosed. The top of this housing piece 18 is so arranged that it is flush with the ground level so that when the sprinkler is not in operation therewill be no obstructions projecting above the ground level kand the sprinkler will vbe practically invisible.

Detachably connected to the top piece 18 is a supporting housing portion 20, of substantially cup shape. Y At the lower end of this portion 20 is a threaded water inlet passage 21 to which the water supplying pipe may be attached. The upper end of the housing por- Y tion 20is preferably flanged outwardly as `indicated at 22, andsuitable screws' 23 or the like detachably connect thetop ofthe housing l portion to the top housing piece 18, a suitable washer. 24being employed to makethe joint water-tight. These' screws are accessible from the top of the sprinkler so 'that the top piece v18 may be disconnected from the housing portion 20 without disturbing lthe ground around the sprinkler. A AboveV the water inlet opening 21 tition or wall 26 having .water inlet passages 27 and 28 so that'wate'r ilowing into the housing I portion 20, in the space 29, may flow through these openings 27 and 28 into awater chamber 30. This partition wall is ref movably supported within the supporting is a par- Y housing portion and may be detachablyv y joined to itrdirectly, but as shown theV wall 26 forms a part of a separate water chamber within the housing portion. The sides of the water chamber 30 are provided preferably by av tube 31 of brass or the like, the lower end of this tube being threaded as indicated at 32 so that the wall 26 may be secured thereto.

The-upper endofthe tube 31 is preferably seicc through the tube 1t and the holes through the sprinklingmozzlesj.- Prilie-rablyY this means comprises a rotatable'member which is rotated rather rapidly as the water liows up through the water chamber. given a rotational or whirling movement, as

it enters the water chamber, as the inlet openings 27 and 2S are so inclined, as shown Figs` 2 and 3, that .the watermust rotate about a central vertical' axis. This rotational movement of thewaterrotatesfthe member 37, which is journaled on a depending stud 38 connected by the arms 39 to the. lowerend of the` tube 16. These arms 39 support a lobe like half ring portion 40, which is rigidly connected tothe armsl and which projects out somewhat in the nature of a cam, being eccentrically curved with reference to the vertical axis of rotation. This ring 40 is struck by a momentum or impact member 41 having an upstanding impacting arm 42, and a horizontalsurtace 43, `the latter being slidably -mounted on the rotatable member 37 and adapted to rotate therewith., A .weighted end 44 normally tends to hold thel impact member out towards the left as viewed in Fig. 1, during operation, so that the upstandingarm 42 strikes againstthe cam ringY 4Q each time the rotatable memberV 37 revolves through one revolution; The impact member 41, how

ever, may slide Ytowards the right, an elongated slot 45 being provided for this purpose, so -thatit may pass Yby the projecting part of the ring 40. Thus the impact member41` is rather Vrapidly rotated .due tothe passage of the whirling water, and impacts'arethus imparted to the yrotatable sprinkling member to move it slowly step by' step and thus cause the water to bev distributed to all sides ofthe sprinkler.

In accordance with an arrangement, of parts as abovedesc'ribed, it is Vapparent that any dirt that may becollecttedbelow the partitionor wall 26 may bereadily cleaned out without disconnecting'the entire sprinkler,

Vby merely removing the Vfastening screws 23 andwithdrawing the top pieeel and the parte connected to it, the partition 26 and the entire water casing providing the water chamber 3() being withdrawn through the top of the housing portion. Another form of the invention is shown in F ig. 4. In this form of construction the water casing within the waterhousing isV rotatable with V,the sprinklingmember. The housing embodies the top piece detachably connected by the screws 51 to the cupfshaped The water" is supporting housing 52. The rotatable sprinkling member 53 is formed at its upper end substantially like the sprinkling member 11 previously described. The lower end ofthe sprinkling member,fhowever, forms the top wall 55 of the water casing 55 which provides the Water chamber 57 within the supportingl housing Vportion 52. The sides of this water A casing are preferably formed by a cylindiical Vtube 58 which is-attachedlby lscrew threads 59 to the'top casing wall 55 -and by screw v threads S0 to the lower wall or partition 61.

This lower wall 61 is provided with inclined inlet openings 62 and 63 to impart arotational whirl to the water in the'water chamber 57.

,l/Vithin the water chamber 57 is a. rotatable .operating member 64 having an impact member 55 adaptedto impact vwith the cam ring 66 provided onthe arms 67 of the .impact member, these parts being similar in construction to the impact vdevice shown Vin Fig. 1,

although, ofcourse, other suitable and equiv- -alent4 means may be employed for imparting slow rotational movements to the sprinkling member as the water flows up through the water casing.

In this form of construction the entire water casing orwater chamber is movable vcrtically within the supporting housingl portion 52 when the water'is turned on, so that the'water casing 56 is substantially above the bottom of the housing portion 52, as Vshown in Fig. 4, when the device is in operation.

' clined inlet openings G2 :mdGS into the water chamber.V VThe entire water chamber 56 is removable with the top piece 50 of the supporting housingN when the latter is:discon nected and withdrawn lfrom the supporting housing portion 52 to provide' access to the inside of thelhonsing portion 52 for cleaning purposes. his operation is eiiected without disturbing the grass or the ground around the sprinkler. f

lNhilethe forms of apparatus herein describedconstitute preferred embodiments of the invention, it is tovv be understood that the invention is not limited to these precise formsof apparatus, and that changes may be made therein .wi-thonet, departing from the scope of thefinven'tion which is defined in the appended claims.V i
