Application led April 21,

My invention has for its object improvements in the sprinkler of my Patent No. l53,0O5, issued May 26, 1891 to the ends of making the construction betterand in some respects cheapening the cost of manufacture and in rendering its action upon the water in distributing it more efficient and otherwise advantageous, all as will appear from the description hereinafter given. My invention consists in whatever is described by or is included within the terms or scope of the appended claims.

' ln'the drawings:

Fig. 1 is a view in vertical section;

Fig. 2 is a horizontal section on the line 2-2 of Fig. l;

Fig. 3 is a perspective view from the underside of the rotary deflector plate;

Fig. 4 is a detail section on lined-4 of Fig. 1.

Referring in detail to what is shown in the drawings, I provide a base member, 10, which in a single cast integral member includes an internally threaded coupling for attachment to a hose or hose stand and a nozzle upon the exterior of which are integral upwardly and outwardly inclined lugs y or bosses, 11, preferably four in number, and

equi-distant apart, in each of which is embedded the lower` end of a` substantially L- shape arm or standard, 12, of wire, the up-r per ends of which are embedded in, and thereby support at a suitable elevation above the nozzle outlet a cap or top member, 13, to which as hereinafter explained the rotary deflector plate or wheel is attached.v

Said top member, 13, comprises a cylindrical, vertical portion, with integral lugs or bosses, 14, `that extend at an incline downwardly and outwardly, in which the upper parts of the standards 'are respectively embedded. The embedded portions of the standards at top and bottom are non-circular in cross section, preferably elliptical in cross section, and their surfaces are transversely ridg'ed, as by means of mutilated screw threads, so that not only are the embedded portions held from turning in the lugs or bosses in which they are embedded, but a strong, rigid connection is made which gives 1927. semi No. 185,516.

is open and light, and inexpensive to make.

The embedment of the end portions of the arms or standards is effected by casting, or otherwise.

The rotary deflector plate, 15, is situated between the lower end of the cylindrical portion of the top member, 13, and the top of an inverted cone-shape water distributor, 1G, the latter having projecting from its upper side a central shank, 17, that enters a vertical recess in said top member, and'which is secured to the top member by. a pin, 18, driven transversely through aligning holes in the top member, and anamiular groove, 19, in the stem, ror shank. rIhe rotary deflector plate is thus free to revolve on the stationary shank or stem, and between the upper side ofthe rotary defiector plate and the bottom of the'top member an anti-friction thrust bearing is providedv formed by balls, 20, in an annular ball race, consisting of a groove, 21, pressed in the upper side of the deflector plate, and an opposed annular groove in a ring, 22, cast or otherwise secured in the bottom of the top member, 13, said ring preferably being of harder metaljthan the ytop member which may be of cast metal. lt will be seenthat under the upward pressureof water flowing from the nozzle against the underside of the rotary deflector plate, the

' tri latter will be lifted from the top of the coneshape distributor, and thus friction at that point prevented, and the only friction will be the insignificant friction from the upward pressure of the rotary dellector plate Cil 24, through the upper part ot the top member, 13, that opens out at the top et' t ie latter, so that when the sprinkler is in operation a central fountain will be produced by the jet of water flowing through such aligning openings.

The rotary detlector plate has a form preterably which may be described as a trefoil, and each toil or arm has near its periphery a hole, 25, Jfrom which on the underside of the plate a concave lip, 26, extends downwardly and outwardly, and from which on the upper sid-e of the plate a lip, 27, extends upwardly and outwardly, so that the water will flow from the underside OiI the deflector plate upward and outward in streams in various directions and by the revolution of the rotary deflector plate' will be whirled around as well as projected radially outward over a large area.

Adjacent each hole, 25, each foil or arm is bent sharply downward to form a vertical flange, 2S, whose vertical surfaces extend tangentially and which by the impact of the water distributed by the cone-shape distrilr utor cause the detlecter plate to rotate nd the water striking the same to be projected radially outward, and along the lower margin of said flange it is bent horizontally inward to provide a horizontal supplemental flange, 29, which is concave on its upper side, so that water will be deflected thereby upwardly and outwardly, and thus be prevented from being thrown downward to the ground immediately around the stand or support for the sprinkler. The angle of the outwardly projecting portion of the supplemental tlange may be changed so that instead of extending upwardly it may extend substantially horizontal, and thus by changing its angle the effeet of it upon the water striking it as far as direction is concerned will be modified.

As the distributor cone, 16 is preferably made of soft metal, a bearing, 30, of harder metal is applied to the top, for the rotary delector, l5, to diminish friction from contact with the underside ot' the latter.

What l claim is l. In a rotary sprinkler, the combination of a frame comprising a base having a nozzle, a top member, standards connecting the base and top member, a rotary delector plate journaled by the top member, a distributor beneath said rotary plate, and aligning Vertical holes through the distributor the rotary plate and the top member, the hole through the top member reaching to the upper end of the latter for the passage of a jet ol water, said holes also alining with the nozzle.

2. A. rotary sprinkler comprising a nozzle, a rotary deflector plate, means for supporting the deliector plate above the nozzle, said detlector plate having downwardly projecting lianges which terminate with horizontally inaverage WELLIM F. WARE.
