SPRINKLER HEAD.
Application filed-March 11, 1918. iserlel No. cancel.
To all whom c't may concern:
Be it known that we, WILLIAM A. KEN- NEDY and ALBERT J Lonrsmenn, both of Providence, in the county of Providence and State of Rhode Island, have-invented certain new and useful Improvements in Sprinkler Heads; and we do hereby declare the following specification, taken in connection with ill the accompanying drawings, forming a part of the same, to be a full, clear, and exact description thereof.
The invention relates to improvements in 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 dirent a stream of water against the exterior wall of the building and through or against the windows thereof.
In sprinklenheads of this character as heretofore produced, a deflector has been employed which has a flat surface or other surface adapted to break the jet into spatters arranged opposite the outlet opening and at right angles to the axis thereof. lhe great objection to theuse of a deflector oi this character 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 deflector which is arranged at right angles to the axis oi": the outlet opening, but the velocity and energy of said stream is at the sometime greatly reduced, which in turn reduces the area of distribution.
The principal object of the present inven= tion 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 decrease the velocity of the stream of water to as great an extent as would a flat deflector and also produce a wider and better distriloution of said stream against the wall of the huilding protected.
A further object of the invention consists in providing the sprinkler with a deflector of the alcove character which is arranged and adapted to receive and direct the stream or? water tangentially to the inner surface of said deflector.
To these ends the invention consists in the novel construction and arrangement of parts hereinafter described and particularly scomprises a tubular nozzle 2, having external threads 3 for attachment to a water supply system and the usual outlet opening a. Secured to, or formed integral with, the frame work 1 opposite the outlet opening 4.- s a deflector 5 which is preferably circular in shape and is provided with an inner curved surface 6 terminating in a pointed plro gection 7 in line with the axis of the nozz e With the above construction it will be seen that the stream of water flowin from the outlet opening will be divided at its center by the pointed projection 7 and directed tangentially along the curved inner surface 6, thereby efiecting such a gradual change in the direction of the flow of the water as not to materially reduce the velocity thereof, thereby resulting in a wider distribution of 1 the stream. Figs. 1 and 2 disclose a deflector from the deflector 5 will be at less than a right angle to the axisof the sprinkler nozzle.
It will also be seen that with our novel construction of deflector, the stream flowing from the outlet opening is received by the deflector tangentially and that said stream. is likewise delivered from said deflector tangentially to the plane of distribution and that as a result a minimum of interference in the velocity, energy, or range of distribution of saidstream results.
It will be understood that we do not wish to limit ourselves to the exact construction and arrangement of parts shown as it is oh vious that various changes in details may be made without departing from the spiritand scope of the invention as set forth in the clairn.
What we claim as our invention and desire to secure by Letters Patent is:
A sprinkler head adapted for tire protec tion, directed backward with respect to the direction of flow through the nozzle, of Such great perimeter that the said tubular stream I covers it but thinly; and a smooth curved intermediate portion continuous in curvature with both said central curved surface and said terminal flaring pet tion in which 1 intermediate portion the curvature of stream direction away from the nozzle direction,
and the spread in breadth of a stream 20 from its dimension at the IIIOZZIG, are sufii ciently gradual to avoid breaking the stream on the surface of the defleetor; the part of said terminal flaring portion which is adjacent tothe said intermediate portion being 25 curved in continuity with the curvature of the intermediate portion.
