SPRINKLER HEAD.

Application led March 11, 1918. Serial No. 221,850.

vTo all whom it may concern):

Be it known that I, ALBERT J. Lonrsmonn, of the city and county of Providence, and State of Rhode Island, have invented certain new and useful Improvements in Sprinkler Heads; and I do hereby declare the following specification, taken in connection with the accompanying drawings, ing a part of the same, to-be a` full, clear, and exactdescription thereof.

The invention relates to improvements 1n sprinkler-heads and is designed primarily for use in connection with that class of sprinkler-heads known in the art 'as open sprinklers which are designed and adapted for use upon the exterior of buildings to direct a stream of Water against the exterior wall of the building and through or against the Windows thereof.

In sprinkler-heads of this character las heretofore produced, a deflector has been employed which has a flat surface arrange opposite the outlet opening and at right angles to the axis thereof. The great objection to the use of a deflector of this character resides in the fact that the stream ofwater issuing from the outlet opening is not only broken up after it issues from the nozzle and when it strikes the surface of the deflector which is arranged at right angles to the axis,

of the outlet opening, but the velocity and energy of said stream at the same time 1s greatly reduced, which in turn reduces the area of distribution.

L'lihe principal object ofthe present invention is to overcome the above objections and to provide a sprinkler-head of this type with a deflector of such a character as not to dc-v crease the velocity of the stream of water to as great an extent as would a flat defiector, and also produce a widerx'and vbetter distribution of said stream against the wall'ofthe building protected.

More specifically tion consists in providing a sprinkler with a deflector of the above character which is arranged and adapted to direct the iiow of water therefrom in different directions and in different Volumes in each direction.

To these ends the invention consists in the novel construction and arrangement of parts hereinafter described and more particularly set forth in the claims, and relates to a species of the generic invention set forth fornithe object of the inven-` and claimed in my pending application filed July 20, 1921, Serial Number 186058, which originally was disclosed and claimed in this present specification.

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

Fig. 1 is a front elevation of a sprinkler head embodying the present invention.

Fig. 2 is a vertical sectional view thereof.

Fig. 3 is an illustrative view showing the application of the sprinkler-head in use upon the side of the building in such manner as to throw a portion of the stream of rwater against the cornice of a building and the remainder of the stream against the wall or window of the building.

Referring to the drawings, 10 represents the frame of the sprinklerhead, 11 the -tubular nozzle having external threads 12 point of intersection of said curved surfaces. As shown the' cur-ved surface 15 1s shorter.

than the curved surface 16, although they /may be of any desired lengths. In conscquence their degrees of curvature are different, and theydeflect water to differing degrees from the axis of the nozzle. The utility of this in enabling the waterto be directed as desired, against different shaped or positioned surfaces to be protected, is indicated in Fig. 3. By reason the fact that the frame 10 is arranged at an angle to the axis of the sprinkler nozzle it will be seen that the'raised rib 17 is in a plane outsideof the axis of said nozzle and that-the stream of water flowing from said nozzle will be divided at one side of its center so that a smaller portion of said stream will flow tangentially and a larger portion of said stream will flow tangentially along the longer curved surface 16. i

y It will be seen that the co tinuous curved surfaces upon the interior ofithe distributor 'will cause a gradual change in the direction of flow of the water in such a manner as not along the shorter curved surface 15 toy materially reduce the velocity, or energy thereof, and also result in the wider distribution of the stream.v

Such a 4construction and arrangement of deflector is desirable for use adjacent the roof of a building so that-a small portion of the `stream flowing from the sprinkler can be directed againstv the cornice of saidbuilding, while the greater portion of said stream will`be directed downwardly against the wall or window of the building as shownA in Fig. 3.

With the above construction of deiector it willbe seen that any desired plane of distribution may be secured by varying the curva- .'ture of the curved surfaces andv different planes of distribution may be secured in the same deflector.

It will be' understood that I do not wish to limit myself to the exact construction and arrangement of parts shown as it is obvious that various changes in details may be made Without departing from thespirit and scope l of the invention ,as set forth` in the claims.

What l claim as my invention and desire to secure by Letters Patent is:

1. A sprinkler head comprising a lnozzle and a deflector associated ixedly with it, said deflector having surfaces, along which separate parts of the water from the nozzle flow, rigidly supported in position with their initial portions approximately tangential to the l stream from the nozzle, and jointly constituting a stream-dividing edge set across the path of the stream at a location outside of the axis thereof, whereby the streamA is divided into two unequal portions which are deflectedvdiversely by said surfaces; said deiecting surfaces having terminal portions which are nextending at diverse angles with, the axis ofthe nozzle at their respective terminations.

2. Asprinkler head comprising a nozzle and a deflector associated ixedly with it, said deliector having diverging deflecting surfaces, along whichseparate parts of the water from the' nozzle How, rigidly supported in position with their initial portions approximately tangential to the stream, one of said deflecting surfaces being shorter than andy having less curvature than the other,

whereby the stream is divided into portions,

one for each said surface, which are dellected diversely by said surfaces.

3. A sprinkler head comprising a nozzle and a defiector associatedv with it having sur- `faces along which separate parts of the water from the nozzle flow; said surfaces having initial portions -approxima-tely'tangential to the low and terminal portions separated from-each other and delivering separated streams, whose stream guiding faces extend at diverse angles from the axis of the nozzle, thereby delivering the stream in sections at diverse angles from the axis.

4. A sprinkler head comprising-a nozzle and a deflectorhaving two defiecting surfaces arranged respectively to receive'adjacent parts ofthe nozzle stream and by their deflection to flatten said parts into distinct sheets; said deflecting surfaces terminating respectively at different angles lfrom the axis of the nozzle.
