To all whom t may concern.-

Be it known that I, ALBERT J. LonPsINGER, -a citizen of the United States, residing at Edgewood, vin the county of Providence and State of Rhode Island, have invented certain new and useul Improvements in Sprin` kler Heads, specification. The invention relates to improvements 1n sprinkler-heads, being a division of the subfject matter disclosed in my apphcation for of which the following is a i patent, Serial No. 221,850, filed March 11,

1918. It is intended that the present atent shall cover by suitable expression in t e appended claims, whatever features of patentable novelty exist in the inventlon herein fdisclosed. Said invention is designed primarily for use in connection with that class of sprinkler-heads known in the art as open rinklers which are designed and adapted gir use upon the exterior of ybuildings to direct a stream of water a ainst the exterior "wall of the Ibuilding and t rough or against the windows thereof. v

In sprinkler-heads of this character as heretofore produced, a deflector has been employed which has a flat surface arranged opposite the outlet opening and at right angles to the axis thereof. The great objection to the use of a dellector of this charmeter resides in the fact that the stream of water issuing from the outlet opening is not only broken up after it issues from the nozzle and when it strikes the surface of the delector which is arranged at right angles to the axis of the outlet opening, but the velocity and ener of said stream at the same time is great y reduced, which in turn reduces the area of distribution.

The principal object of the present invention is to overcome the above objections and to rovide a s rinkler-head of this type with a dbilector o such character as not to decrease the velocity of the stream of water to as great an extent as would a flat deilector, and also to produce a wider and better distribution of said stream against the wall of the building rotected.

A further object o the invention consists in providing the sprinkler with a deflector of the above character which is arranged and adapted to receive and direct 'the stream 7, dated December 19, 1922i.

Application for reissue of water tangentially to the inner surface of said deflector.

A further object of the invention consists 1n providing the sprinkler with a. deflector of the above character which has a continuous curved surface extending from the sprinkler nozzle and partially surrounding the outlet opening for directing and controlling thellow of water from the moment it leaves said nozzle.

It is a result of the invention that the relative amount of water projected from various segments of the deector can be controlled so that while the whole is projected to one side of a plane through the axis of the nozzle, so as'to strike an adjacent plane surface, such as the outside Wall of a building, the distribution of liow may be either made approximately uniform from all parts of the delivery edge of the delector, or approximatel uniform toward all the parts of the wal which it is to strike, or may be otherwise controlled, either to concentrate a considerable liow at some particular region or regions, or to avoid concentration. This is accomplished by the provision 'of a ridge or raised part of the surface of the detlector over which the water Hows, which ridge causes the water, which in the absence of the ridge would flow out straight in the middle in much larger volume, to be distributed somewhat transversely from the middle of the deflecting surface and to 'low out more toward one side or the other, thus giving both a' reduction of central flow and an increased throw toward each side. In such a case'more water is supplied to the sides, where a given angle of the deflector has to supply a greater linear length of wall, because of the Obliquity with which it strikes; and the throw in that direction is increased both in quantity and in force, which means throwing to a greater distance.

To these ends the invention consists in the novel construction and arrangement of parts hereinafter described and more particularly set forth in the claims.

In describing the invention in detail, reference will be had to the accompanying drawings in which,

Figure 1 is a front elevation of a sprinklerhead embodying my novel construction.

' It will also Figure 2 is a vertical sectional view on line :uf-fp 'Figure 1.

Figure is' n transverse line y-/y Figure 1.

Referring to the drawings 1 represents a tubular nozzle having external threads 2 for attachment to a water supply system and the usual outlet opening 3. Formed integral with, or secured to, the nozzle 1 is a deflector 4 which-coin rises a body ortion 5 extending g e y parallel m t e axis of the nozzle 1 and located adjacent to and curved transversely so as to artially surround the outlet opening 3. y'lille outer free end portion 6 of the delector 4 extends laterally from the body portion 5, as shown in Figure 2, The interior Sul-flux of Seid defleotor 4 is curved both transversely and longitudinally and the ctldprton 6 its provided upon its interior with `tuno eontinuious curved surfaees 7 and 8, having e, raised rib 9 at the point of interseetiou of said curved surfmes, as shown in Fi re 1.

Vith the above construetion it will be seen sectional View on 'that the stream oi water lowing from the outlet opening will be directed along the curved body portion 5 of the deileoter 4 and flow tangentially along the continuous curved inner suefaee of said deieetor 4 and be distributed imm the outer :free end 6 of said distributor tangentially to the plane of dirihution. It will also he seen that a portion of the stream issuing from the outlet :Toning will be dincted against the raised b 9 and be distributed transversely as well as from the curved surfaces 7 an 8.

be seen that the eontinuous interior of the disin the d mall- .emved surfaces upon the triinltor will cause a gradual change direction of Haw of the water in sue ner lnennt to materially reduce the velocity,

or ener thereof @nd also will result in the wider distribution of the stream. Inasmueh as the does not extend'tothe delivery edge of e tor, water is diseharged from allvparts of the edge of the defleetor in a si f continuous diverging sheet.

It wi also be seen that by changing the euroatune of the outer end 6 of the distributn'r die direction of distribution can likewise be changed so that the Water can be distributed therefrom either at right angles to the axis of the nozzle or at an acute angle or an obtuse angle thereto.

I .claim as my invention:

l, A sprinkle-r head, comprising a nozzle combined with a deflector, the said deflector being arranged starting in substantially the initial direction of the jet and curving with smooth non-spraying surface through substantially a right angle therefrom to a delivery ed e spreading throughawideangle, whereby t e momentum of the water i'lattens the current against the dector inw Spreading shed form combined with a rear and side plate limitlng the delivery to a spread not exceeding two right angles; .said dleetor having in its dellecting tending from said veel' plate out toward Said edge, and ending within the eurnent, Whereby water has access to flow from substantially all of said edge, said ridge being arranged and adapted to influence the lateral distribution of water over the surfaoe of the defieetor. y

2. A sprinkler head comprising a nozzle combined with a deilector which, starting in the direetien of the jet, is curved eencavely and smoothly across the initial direction of the jet, the directions to which said curvature proceeds running through a wide angular ran about said initial direotion as an axis, there being in said deflecting surface a ridge whose surface elements partake of the first described eurvature and nontrol quantitative distribution of water in the said range.

surfaee a ridge ex- 3. A sprinkler head comprising a nozzle continuous sheet.
