27 Claims. (c1. 299-68) l My invention relates to a waterv sprinkling device that is especially designed for use on lawns, golf courses, gardens, orchards or wherever a thorough distribution of water is desired overa relatively large area and the principal objects of my invention are, to generally improve upon and simplify the construction of the .existing forms of rotary Water sprinklers and to provide a sprinkler of the rotary type that is relatively simple in construction, inexpensiveA of manufacture and which willbe very effective in performing the functions for which it is intended.

Further objects of my invention are, to provide a water sprinkler, wherein the housing that carries the jet nozzle is caused to slowly rotate about its axis as a result of the impingelnenty of a relatively small jet of water against a wheel having radially disposed blades and which wheel functions for the distribution of water throughout the area immediately adjacent to the point where the sprinkler is positioned, further, to provide a sprinkler having a housing within which Vare formed separate chambers, one of which Ycontainsv the vertical bearings for the housing and also the gearing that is utilized for imparting rotary motion to said housing, the other chamber functioning as a water circulation chamber and having jet nozzles projecting therefrom and further, to provide simple and eflicient means for controlling the jet of water that impinges against vthe blades of the Water spreading wheel and likewise for controlling the pressure and force of said jet of water.

Further objects of my invention are, to provide a sprinkler of the character referred to having a separate water chamber that is connected to the source of supply and from which projects the main jet nozzle, to provide simple and eflicient means within said Water chamber for producing, aY perfect bala-nce of thethrust resulting from theV pressure of the water passing through said chamber and further, to provide an improved construction wherein Wear between moving parts of the rotating housing vand the gearing container therein is minimized.

. A further object of my invention is, to provide improved packings for the bearings between the v Water housing and its support so as to practicallyeliminate `the possibility of the development of wear iii-said bearings as a result of the presence of sand, grit and the like that passes through the sprinkler with the Water that is delivered to and discharged therefrom.

A further objectof my invention is, toprovide a lrotary sprinkler having relatively simple'land efficient means whereby the necessary adjustments may be made so as to cause said sprinkler to operate at highest efciency under all conditions of variable water pressure, speed-of rotation of the nozzle carrying head and the variable areas to be covered by the Water that is discharged from the rotary head.

With the foregoing and other objects in View, my invention consists certain novel features of construction and arrangement of parts that l Vention, and with the lower portion thereof shown in vertical section.

Referring by numerals to the accompanying drawingswhich illustrate a practical embodiment of my invention, 10 designates a housing preferably cast from metal and which housing is mounted between the upper portions of a pair of runnersY 11. having upturned ends 12, thus enablingY the base structure and Ythe parts carriedthereby to be readily drawn over the surface of the ground and consequently permitting thesprinkler to be readily shifted from one position to another.

Projecting from the upper portion of-housing 10 is a connection 13 for a supply `pipe or hose 14 and arranged in the lower portion of the side wall of housing l0 is a removable plug lowhich permits access to the interior of the housing. in order that accumulations such as sand and'siltmay be lso means of a plug 18 that is screwed into the lower portion of said tubular post and the lower portion of which plug bears against the bottom Wall of housing 10.

Suitable packing rings 19 are arranged between plug 18 and the bottom of housing 1) and likewise between the top of said housing and a shoulder that is formed on the tubular standardl'l.

Thewall of the tubular standard 17, within the chamber 18 in housing 10, is' perforated as designated by 20, and surrounding this perforated portion of the standard and spaced apart therefrom is a concentrically arranged perforated strainer 21. This strainer is effective in preventingk sand, silt and other foreign substances from passing from the supply pipe upwardly through the tubular standard 17.

The upper portion of tubular standard 17 is provided with periorations 22 and formed integral with and projecting upwardly from the tubular @standard immediately above these perforations isapostzs. Surrounding the upper perforated portion of the standard V17 .is a housing 24 and projecting carrying at its outer end a removable jet nozzle 26, whichis designed to discharge the main jet of water from the sprinkler; j

4 Screw-seated on thetubular standard 17, irnmediately below housing; 24, is a ring 27 provided at. its upper'end witha flange 28 having an inclinedlupper surface and said 'ring 27 may be located' inrit-s adjustedposition upon Ythe threaded portion of standard lby means of a clampn ing screw 29 that passesY through vears 30 that project outwardly from said ring and theY latter being split between said ears.

Screw-seated on thelower 'end of housing 24 is a ring 31having aA flange 32 that prcjectstoward flange 23 and resting ontopof ange 32 is the outer portion of a packing ring or washer 33 of leather,-rubber or suitable compositionand the `-inner portion of this packing ring rests on the -inclined upper face of' ange 28.

Seated within the lower portion of housing 24 is a retaining ring 34 that clamps the outerportion of vpacking ring 33 against 'liange 32. Y

Surroundingl the tubular post 17 and bearing directly on top of Vthe inner portion of packing ring 33 above flange 28 is a retaining ring 35 of metal* and disposed on top thereof is a packing ring 86,y preferably vof felt which surrounds the tubular postl and which isjretained in position by an overlying ring'37 of metal. Y

Bearing on-top of the ring 37 lis the lower end of an expansive coil sprin'gii and which surrounds the perforated portion of pcst-17.' Screw-seated on the upper portion of tubular post 17, is'va ring 39 which is heldr by a lock ring 40andbearing against the underiace of this ring 39, which is inclined, is the inner portion of a packing ring 41 of leather, rubber or suitable composition. The outer portion of this packing ring 'bears against an internal shoulder that is formed on the wallofhousing 24 and screw-se`ated within said housing and bearing against the outer portionv of said packing ring is aclainping ring`42, preferably of metal.

Bearing against the underside of the inner portion of thepacking ring41 is a ring 43 of metal Vand positioned against the underside of this .ring Sra packing ring 44 of felt 0r analogous ma,- terial that `is enclosedan retainedin position by rinea. 'i Ik The inner and outer edges of the retaining rings 35 and 43 are concentric with and spaced apart from tubular post 17 and the adjacent retaining rings 34 and 42, with the result that there is no contact of metal between the tubular post 17 and the metal rings that retain the packing rings 33 and 41 in proper position against the flanges 28 and 39. w

Theupper end of expansive spring 38 bears against the underside of the retaining ring 45.

Asa result of the construction just described, the'pressure of the Water passing through the chamber within housing 24 is directed equally against the packing rings 33 and 41, with the result that uid pressure tight joints are produced between both ends of housing 24 and the tubular post 17 and the pressure exerted by coil spring 38 is also Veffective in producing and maintaining these tight joints.

Secured in any suitable manner to the inner face of the side wall of housing 24 are one or more vertically disposed plates 46 that function as baffles to prevent the whirling of waterrduring its passagel through the chamber within said housing.' from the side 'thereof is a short inclined tube 25 Detachably secured in any suitable manner on top of housing 24 is a gearhousing 47, the bottom plate of which is spaced a short distance above the retaining ring 39 so that there is an open air space 48 between the top of housing 24 andthe bottom of housing 47. This space 48 permits any water that would otherwise tend to accumulate on top ofthe flexible head of housing 24,-to be thrown outwardly by centrifugal force away lfrom the sprinkler during the rotation of said head and.

the lparts carried thereby. Y

VFormed integral with the bottom wall of hous ing r47 and disposed concentrically with vrespect to' post 23, which projectsV upwardly into the chamber withinsaid housing, is an annular wall Positioned on the lower portion `of Athcfpost '23 is a bearing ring 50 against which engages the upturned inner edge of ak packing ring 51 of leather or analagous material and which ringA4 rests on the bottom plate of housing 47y within the space encompassed by wall 49. The'upturned inner edgeof this packing ring is caused tohug rthe bearing ring 50 by a split compression ring 52 that encircles said upturned inner edge.

Arranged within the wall 49 and resting on the outerpoition of packing ring 51, is a spacing ring 53 and bearing on the top thereof is a channel shaped ring 54 that functions as a cup race `for a series of ball bearings 55.

yThe inner edge of ring 54 is spaced a slight distance apart from post 23.

Screwseated on the intermediate portion -of post'23' is a conebearing ring 56, the lower end results from the upward pressure o f an expansive coil spring that is disposed be'twjeen'thie bearing at the upper end of postk 23 Aandthe top plate of the housing and which spring is hereinafter more ,fully described. p

Screw-seated in the upperend o i'wall 49 is the lower end o1" a collar 60 and positioned `on aflange yno retained in position within the collar 60 in any suitable manner.

By screwing collar 66 downward, pressure is `applied to parts 54, 53 and 51 to maintain a tight joint between the anti-friction bearing in the lower portion of the gear housing 47.

Secured in any suitable manner to the ,upper vend of post 23, is a worm wheel 62, and they upper thelower portion of said ring ange and bearing on top of said bearing ring 64 is ythe lower'end of an expansive coil spring 68. The upper end of this spring bearing against a removable cap 69,

`thatcloses the upper end of the chamber within ring flange 65. As above set forth spring 68 tends to lift the gear housing so as to maintain a proper bearing between cup race 54, bearing members 55 and cone bearing 56 and to also maintain proper bearing between the upperend of standard 23, bearing members 63 and the bearing cone 64.

Thus by the use of the expansive spring 68, the rotary head or housing practically floats on its bearings while the sprinkler is in operation.

Secured to the upper portion of housing 47 on opposite sides thereof are the lower ends of an inverted U-shaped handle 76, by means of which the sprinkler may be readily lifted and carried.

ends thereof against the anti-friction members I of the bearings 71.

Secured on this shaft 73 is a worm 75 that engages the yteeth of worm wheel 62.

Secured on shaft 73 is a worm wheel 76 that engages ,a worin 77 and the latter being secured on a shaft 78 that is formed in two parts telescopically connected and the outer ends of said parts bearing in suitable anti-friction bearings in the side walls of housing 47.

A spring 79 is arranged between the two parts of shaft 78 for maintaining the cone bearing on the ends thereof in yielding engagement with the anti-friction bearing at the ends of said shaft and this shaft 78 is arranged below and disposed substantially at right angles to shaft 73. L

Secured on shaft k78 is agear wheel 80 that meshes with a pinion 81V and the latter being secured on a shaft 82 that is disposed slightly above and `to one side of shaft 78 and above and atright angles to shaft 73. Y

Shaft 82 is formed in two parts that are normally forced apart by an `expansion springV 83 in order to maintain the cone bearing rings 84 that rvthe side walls of housing 17. One end of shaft vdrip off the gland or stuffing box and not pass therethrough.

the unseating of pin 92 and this cap is retained is located externally of the wall of housing 47 and formed onrthe intermediate portion of thehous'- ing of said gland or stuingbox is a circumferential ange 87 that functions tooause water'to The two- part shafts 73 and 78 are arranged so that the thrustreceived by the worms carried by said shafts is against the fixed cones on said shafts while the slip cones on the opposite ends of said shaftsfare retained against their bearings by the expansive springs 74 'and 79 and shaft'82 and' its bearings are arranged so that the yiixed cone S4 receives the outward thrust that is impressed on 'shaft 82 by the bladed wheel while the same is in motion and thus the slip cone 84 is relieved of the thrust forces. i

All cones carried by the shafts 73, 78 and 82 are secured by pins to the parts of the shaftsso that said cones and shafts rotate together.

Extending diametrifally through shaft 82, just beyond the gland 86, is a pin 87a and bearing thereagainst, is the central portion of a combined driving and' water spreading wheel comprising a disc 88 that isprovided on its inner focus adjacent toits outer edge with a series of blades or vanes 89 that receive a jet of water from a nozzle hereinafter more fully described and the impact or force of the water against these blades or vanes imparts rotary motion to the wheel and to the shaft 82, upon which it is mounted.

Formed integral with and projecting inwardly from the disc 88 of the bladed wheel, is a ring flange 88a that encircles the gland 86 and the edge of said ring fiange surrounds flange 87. This ring flange is effective is protecting the gland 86 againstthe inward passage of water and foreign substances carried thereby for while the wheel is in motion any water that may passY inwardly along theY inner face thereof, will be kthrown radially outward by centrifugal force as it passes unto the outward surface of said ring ange v888. Projecting outwardly from the center of this wheelY is a hub 90, in which is formed a diametrically arranged slot 91 and occupying said slot is a pin 92 that passes diametrically through shaft 82. v

Positioned upon hub is a cap 93, the flange of which overlies the ends of slot 91 to prevent in position on the hub 90 and the end of shaft 82 by anut 94 that is screw-seated on the threaded end of said shaft. By tightening nut 94 the central portion of the wheel is clamped'against pin 87 and thus saidwheel is very firmly secured to shaft 82 and at the same time it may be readily removed therefrom.

Seated in the side Wall of housing 24 on the same side` of the rotating head with the water compact and spreading wheel is the lower threaded end of an elbow'tting 95 and arranged between said fitting and the wall of the housing is a packing ring 96 against which bears a gland nut 97.

Screw-seated in the upper portion of AVthis el- A bow fitting is the lower portion of a vertically disposed tubularv member 98. and arranged be- Ytweenthe members 95 and. 98 is a packingring 99v against which bears a gland nut 100.

The upperend of tubular member 98 terminates in a'horizontally disposed head 19,1' and positioned against the open end of said head 101 is theopen lower end of'aV short tube 102. Removably seated in vtheopposite end of: this short tube isajet nozzle 102EL that is adapted `to ds- 1 rizo charge a jet of water against the blades 89 on ldisc 88.

.A packing ring 103 is interposed betweenthe contacting edges of the partsl 101 and 102 and ksaid parts are connected by a horizontally dis posed pin or bolt 104 on one end'of which is mounted a clamping nut 105, beneath which is disposed a suitable packing ring.

The construction just described enables the tube 102 and jet nozzle 102at to be raised orlowered so as to regulate and control the lpoint of yimpact between the jet of water that issues :from said nozzle and the blades or vanes 89.

A further adjustment of the jet nozzle toward `and away from the axis of the elbow tting Ais-,provided by screwing .the lower portion of tting 98 into or out of the upper portion of elbow -tting 95 and locking `said member 98y after adjustment vby tightening gland nut 100.

Screw-seated in `thelower portion of the nt- -ting 95 vvdirectly opposite the leg that is screwseated inthe lWall of housing 24, is a tubular plug 106 closed at its inner end vby a plate or disc 107 and located between this plug and the wall of fitting 95 is a packing .ring 108 that is retained in .position by a nut 109 that is screwseated on theouter portion of said plug.

. This plug functions as an adjustable `pressure regulator to control` the volume flow of water from housing 24 through the elbow tting 95, tubular member 98, tube 102 and jet nozzle 1028L and saidadjustable plug is locked after adjustment, by tighteningnut 109.

Seated in thewall of fitting 95, just above the pressure regulating plug 106, is a removable plug 110, which when removed permits a pressure gauge to be inserted into fitting 95 to ascertain the pressure of the water passing therethrough and-thus yielding the requirement for adjustment .of plug 106.

In the operation of my improved sprinkler, water enters housing 10 through supply line 14 and after passing through strainer 21 and apertures 20, said water passes upward through tubular member 17 and out through apertures y22 to the chamber within housing 24.

From housing 24 water passes through upwardly inclined tubular member 25 and `discharges through jet nozzle 26 and. this jet of water -is distributed throughout a wide radius, as the head or housing rotates on the upper portion of tubular standard 17.,

`The Water passing through housing 10 is strained as it passes through the strainer 21 and fall sand, silt and other foreign matter that cannot pass through this strainer, accumulates in the settling chamber 16 and may be removed frornvtime to time by removing plug 15 that normally closes the cleanout opening.

The pressure of the water passing through the chamber in housing 24 is applied uniformly to vthe 4packing rmembers that close the upper and lower lends of said chamber and this pressure is effective in forcing the flexible packing members 33-and 41 outwardly against the flanges 28 and 39 and during the rotation of the housing serve as bearing members are protected against comparatively rapid wear which would otherwise result .if they were subjected to the action of sand, slit or the like.

Water from the chamber withinrhousing 24 passes through elbow fitting 95, tubular member 98, tube 102 and jet nozzle 102 and the jet of Water that discharges from this nozzle, impinges .against the blades or vanes 89 on the water spreading wheel, thereby imparting rotary motion to said wheel and its shaft 82 upon which said wheel is mounted.

The blades or vanes 89 are shaped so that they will deflect and throw the water that strikes against them, outwardly for a considerable area immediately adjacent to the sprinkler and which i area is not covered by the water that discharges from jet nozzle 26. As a result of this arrangement the entire area of the ground surface immediately adjacent to the sprinkler receives water from said sprinkler while the same is in operation.

As heretofore stated, the volume flow and pressure of water through elbow fitting 95, tubular member 98 and jet nozzle 102BL may be accurately controlled and regulated by proper manipulation of plug 106 and the degree of pressure discharging through this jet nozzle may be readily ascertained by connecting a suitable pressure gaugeto the opening that is normally closed by plug 110. 11,.

After shaft 82 is rotated as a result of the imp 'ngement of the jet of water from nozzle 102 against varies or blades 89, pinion `81, meshing with gear wheel 80, imparts rotary motion to shaf 7S and through worm 77 and worm wheel 76 this rotary motion. is imparted to shaft 73.

Worm 75, carried by shaft 73, engages worm wheel 62, but is secured on the upper end of Ypost 23 and as a result housing 47 and parts carried thereby is caused to rotate about the axis formed by post 23 and tubular standard 17 and during such rotation, said housing 47 is `supported bythe anti-friction bearings 55 and 63.

The pressure of the water within the chamber in housing 24 is equalized against the packing-elements at both ends of said water chamber and the spring 68 that is interposed between the upper one of the anti-friction bearings in the gear chamben' tends to equalize the pressure upon said bearings with the result that the entire head or housing and parts carried thereby rotate freely upon the axis formed by the tubular standard 17 and post 23 and the only metal to metal contact vbetween the flXed and rotating parts are the Vcone bearings, races and anti-friction members that y,

function as anti-friction lbearings between the housing and the axis thereof. Y

The chamber within housing 47 islled, or partially filled with grease or a heavy liquid lubricant, thereby providingample lubrication for all 1L.

operating .parts within said housing.y

The felt lpacking ring 61 contained within the upper portion of member 60 prevents the dust and grit from passing downwardly into the chamber occupied by the anti-friction bearings 55 and the Il- Vbearing parts `that cooperate therewith.

Thus the head comprising the housing 24 and 27 (which are separated by an open airspace) is rotated upon the'tubular standard 17 and post'23 and the jet of Water issuing from jet nozzle 26 and the water .that discharges from `jet nozzle 102a `(which is distributed by the bladed wheel) is distributed throughout an area of considerable radius with thesprinkler as a center.

In assembling and adjustingthe rotary head tween the water chamber and-the support upon for operation, the bearing ring 56 is screwed downward into annular wall 49 until balls 55 are engaged and when such engagement takes place, the entire head or housing is lowered to a slight degree so as `to properly adjust the packing ring 41 s0 that the inwardly projecting portion thereof lies smooth and flat against thevunderside of ring 39. f

Thislowering of the housing also properly adf justs the inwardly projecting portion of ring 33 so that it lies smooth and flat upon flange 28. The parts 28, 32, 39 andl the'ange against which the outer edge of-packing ring fil engages are constructed so that when their outer faces align with each other or occupy the same horizontal planes, the packing rings 41 and 33 are properly positioned so as to operate at highest eiciency and produce the desired watertight joints at the ends of the water chamber within housing 24. 1 Y

Thus it will be seen that I have provided a rotary sprinkler having a rotary head within-which are formed separate water and gear chambers, with a main jet nozzle projecting from the water chamber and with the gear chamber containing 4 the necessary gearing for imparting rotary motitl tion to the head.

The rotary head is mounted on a post or standard so as to rotate thereon with minimum friction and there is no metal contact in the bearings bewhich the housing rotates. v-

The iiexible packings at both ends of the water chamber are acted upon by the pressure of the water passing through said chamber and the entire bearing of the rotary head uponvthe standard is carried by anti-friction bearings that are disposed within the gear housing and which latter is filled with heavy oil or grease to facilitate thel operation of the gears and operating parts within the gear compartment. i

The water chamber and gear chamber, although connected to each other are separated by an open air space and the joints between the i post or standard and the water and lgear hourings are packed so as to effectually prevent water from entering the gear-chamber and likewise for preventing grease or oil from entering Vthe water chamber.

When the sprinkler is not in use, the iiexiblc packing elements at the ends of the-water chamber are rrnly held in place and in proper position by spring pressure and thus said parts are retained in position so as to function properly when the sprinkler is subsequently operated.

A further feature of my invention is, the Yprovision of relatively simple and effective means for regulating the pressure of the water that discharges in jet form unto the bladed wheel and kthe means for regulating this pressure is located in the elbow tting that leads from the water chamber so that said pressure regulation is entirely independent 'of the pressure of the water that'discharges through the main nozzle 26.

A further feature of my invention is, the wide ,range of adjustability of the jet nozzle that diand said head while in operation practically 'a spring arranged between-said standard and 'head for yieldingly supporting the latter, there "of'thefwater chamberandsaid standard, a jet nozzle projectingfrornthe water chamber, antifriction bearings arranged within thef gear chambladed wheel connected-to said driving gear coniioats on its bearings with a minimum of friction and very littleif any wear. Y
