Application filed July 31, 1913. Serial No. 782,251.

T o all whom it may concern Be it known that l, Homin S. MUNsoN, a citizen ot' the United States, residing at Redlands, in the county of San" Bernardino ,and State of California, have invented certain new and useful Improvements in Sprayers; and I do hereby declare the following to be a full, clear, and exact description of the invention,- such as will enable others skilled in the art to which it appertains to make and use the same.

This invention is in the nature of a sprayer generally adaptable to all the pnr poses for which such devices are used but especiallyv adapted 'for use with underground piping systems of lawn irrigation.

The object of the invention is to provide a sprayer of improved construction which will cause water to be sprayed evenly over the entire area from the center of the sprayer to the circumference of that part of the ground reached by the water.

A further object'in constructing such an improved sprayer is to ctonomize in the cost of production by the simplification thereof and to provide a construction which will be proof against breakage or disarrangement of arts with ordinary usage.

`ith these objects in view, the invention consists in the improved construction, arrangement and combination of the parts of a device of the character specified, which will be hcreimiitertully described, and aftei-wa rd specifically claimed. n

lu order that the' construction and oper ation thereof may be readily comprehendcd, l will now proceed to fully describe my invention in connection with the accompanying drawings, which illustrate an approved embodiment thcrcof, and in which drawings.r

Figure 1 represents -in perspective, a sprayer in position on a lawn. Fig. a view in vertical central section, the supply pipe being shown in elevation. Fig. 2, a trag mentary detail view in side elevation.

vertical sectional view of the sprayer illustrated in F ig. 10, and, Fig. 1t), a perspective view of a sprayer'upon a bridge or support to adapt my inventlon for use with hose.

Like reference characters indica te the same parts wherever they occur in a plus Referring specifically to the drawings, 11 indicates the main body which supports'my improved sprayer in the earth, the top 12 thereof being preferably circular and slightly above the earth and having its outer portion beveled ofil as at 125 so that its circumferential edge 1 4 will be substantially on a level with the surface of the earth, the latter bcino indicated at 15. This body 11 is provided with diametrically opposite depending lugs 1G near its periphery, the lower ends of which extend inward horizontally forming hooks 17 over which engage radial flanges 1S extemling from a sleeve l1l)..,which interiorly threaded to receive the exterior threads Q() of a water discharge pipe Q1 which is located verti cally in the earth and has connection (not shown), with the mains or supply pipes or"A any available Water system. 'lhe main body l1 is receesed centrally to receive the active elements of my sprayer which comprise a cup 22 shown in detail `in Fig. il, having its bottom perforated at Q23, and provided with a peripheral horizontal flange Q4, adapted to rest. upon the radial arms 18 of the sleeve l5), a packing 'ing 25 being inserted between said arms an( [langes and a vertical annular flange Q6 being provided atV the outer edge of the horizontal flange '24. Upon thisl peripheral vertical flange 2G rests what l term my nozzlel plate Q7. shown in detail in Figs. 5 to 8. Thisl nozzle plate 27 is flat except `for certain elevations and depressions formed at a .short distance within its perilihcry. thc llat portion at the periphery supporting thc plate on thc vertical peripheral ange lo of the cup 22. The depressions and elevations rc't'crrcd to consist of a circular sci-ics oli raiscd hollow ribs Q8 altcrlnlt'c'l. in a circular line. with dc['ir\'\,sscd

grooves 73S). circular holes 30 being punched,`

in thesamc circular line at the junction of one end of cach raised rib 2S with the adjacent cud of the dern-esseri groove Q9, thc opposite ends ol' thc ribs and grooves being merged into cach other and forming outwardly extending surfaces i.

Upon the top of the nozzle plate 27 is placed an inverted ca 32 having a depending `annular vertical ange 33 which incluses the vertical peripheral iiange 26 of the inverted cup 22 and also the ,flat outer edge of the nozzle plate 27, the cent-ral portion of the top of this inverted cup being open as at 34. rI`he recess in the main bod 11 is {iarcd at the top as at 35, and sai. lflared portiomand in fact, the whole recess in the body is axially concentric with the included parts and the supply pipe 21.

To pla "e my sprayer in position', the supply pipe is bron lit `nearly to the surface of the earth and t e sleeve 19 screwed there- Aupon to the proper height. The other parts described may be placed in position on this sleeve or the other parts may be assembled together before the sleeve is threaded on the pipe 21. In either instance, the'packing ring. 25 will rest upon the radial arm 18 and the sleeve 19, the flan e 24 of the cu 22 will rest upon the pac ing ring, the at outer portion of the nozzle plate 27 will restupon the upright peripheral flange 26 of the cup I22, the cap.32 will inclose the cup 22` and .nozzle plate 27. Within its depending vertical peripheral liange 33 and the main body `11 can be then placed inr osition` with the lug 16 out of alinement wit the radial arms 18 of the sleeve 19. The lower faces of the radial arms 18 are beveled oii so as to make said arms Wedge-sha ed and circular, and afterthe main body as been dropped into position as aforesaid,I with its lug 16 out of alinement with the radial arms 418, said body may be turned upon the general axis ofall the described parts which Will carry the hooked ends 17 under the radial arms 18 of the sleeve 19 and cause said hooks to travel under the inclined or v'viredgeshaped Y under' surfaces of said radial arms 18 until4 the packin ring 25 is properly compressed to form a c ose Water tight joint and to hold all the parts in active position.

In operation the Water passin through the pipe 21 will be strained throng the perorated bottom'ofv the cu 22 from, vv hence it will pass upward and Wi l be diverted into a circu ar course by means of the depressions and elevated ribs in the -nozzle plate, thev Water passing under the elevated ribs and outithrough the circular opening30 formed at the junction of adjacent ends of the depressed grooves 29 and raised ribs 28. The water rushing through the openings-30 in a circular `path under the raised ribs 28 will be further guided in a circular ath in the depressed groove 29 until it stri 'es the top `of- 'the inclined parts 31 which will deflect it upward in a tangenital line through the openings 34 of the inverted cap 32- and also through the dared opening 35 of the inain body 11. A plurality of streams of Water -Will thus be thrown outward from the sprayer and will reach all parts of the lawn -or other ysurface withinthe limit of the torce yof the streams.

' In order to adapt'the sprayer as described for use with a hose, I provide a bridge 3G (see Fig. 10), having a threaded thimble 37 .L

projecting from its raised center .upon which .a main body 11a may be engaged by its internal thread 11b, (see Figsft) and 10), said' main body being provided with va recess 11 in the upper portion of which is accom modated a cup 22a, anozzle plate 27it and inverted cap 32', Vsaid part being constructed in the manner hereinbefore described and the cap 32a being provided with a contrai opening 32 for the delivery of Water in 'the manner before described.

The bridge 3G is preferably composed of two substantiall triangular parts 38, the outer sides of W ich form the rests-for the Whole device, said triangular portions being integral and their point of junction at the center being, raised and hollow, a suitable coupling 39 being provided .for a hose .tO,

'the hollowlof the bridge communicating beu tween the hose and the sleeve 37 as before described, upon which the sprayer is mounted It `will be observed that all the parte oir my improved sprayer are of simple and ecenomical manufacture. The 'pipe 21 Wiil be ordinary piping, the sleeve 19 with its radial wedge-shaped arms 18 and the main body 11 with its lug 16 will be cast, while the interior parts 22, r27 and 32 may be stamped up, each by a single operation, out of :ordinary sheet metal. By simply turning the main body in reverse direction fromlthat hereinbeforev described, all the Working parts may be removed from the -supply pipeafter which the pipe may be plugged if desired. Ordinary means may be provided, when desired, to cut/0E the supply of Water from the pipe 21 at sufficient distance below the surface of the earth to prevent freezing, such devices being old and well known and forming 11o part of my invention.

While I have specically described the exact constructionv and arrangement of the component parts of my invention it will be -obvious to those skilled in the ari: to which the invention most nearly appertains, that` slight changes and variations ma be made therein, within reasonable limitatlons, without departing from the spirit and scope of the invention. l
