SPRINKLER.
Application filed June 1, 1927.
This invention relates to improvements in sprinklers and particularly to one of that type especially adapted for sprinkling square or rectangular areas, the present device representing improvements over the type of sprinkler shown in my copending application for patent, Serial No. 156,228, filed December 21st, 1926.
The principal objects of the present invention are to provide a sprinkler of this general character so constructed that the area will be more evenly and eficiently sprinkled than was the case with the previous device; there is less tendency for the same to choke up when particles of dirt and the like are in the water; and the volume of water issuing from the sprinkler may be regulated independent of the pressure and volume at the hydrant.
A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purpose for which it is designed.
These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.
In the drawings similar characters of reference indicate corresponding parts in the several views:
Fig. 1 is a diagrammatic plan of the area to be sprinkled showing my improved sprinkler as installed in connection therewith.
Fig. 2 sprinkler.
Referring now more particularly to the characters of reference on the drawings the sprinkler comprises a base member 1 having a centrally disposed tapped boss 2 for conncction to a supply pipe 3. Removably screwed onto and projecting upwardly from the base the main body or head 4 of the sprinkler, a. substantially semi-spherically shaped member which forms a hollow enclosure with the base. Removably held in place by and between the body and the base is asubstantially cone-shaped screen 5, whose axis is alined with that of the boss and pipe. This shape of screen prevents the same from being strained and buckled by the force of the water.
Adjustably screwed into the boss 2 from inside the head and above the pipe 3 is an intake-volume control. valve 6--atubular member closed on top and having side is a sectional elevation of the Serial No. 195,691.
ings 7. The water entering the nozzle therefore is all deflected laterally instead of straight up. strikes the screen to tend to flow along the same, thereby moving foreign matter toward the apex of the screen and keeping the same clean at the base portion where it is most needed. When the valve is set so that the lower edges of the openings are flush with the inner junction of the base and boss, as shown, the greatest possible volume of water will enter the sprinkler head. l Vith the turning down and lowering of the valve from this position the operative area of the openings becomes decreased, as will be evident, thereby altering the volume of water which may enter the head without interfer ing with the pressure. The boss 2 is of sufficient length so that the valve may be thus screwed down until it is practically closed if desired without interfering with the upper end of the pipe 3.
The sprinkler holes 8 in the body (which is somewhat thick) are all drilled radially from the center of the body and extend all around the same. The upper row of such holes forms a four curve-sided symmetrical pattern about the body as shown in Fig. 1. The uppermost holes A in this pattern are set 90 degrees apart about the circumference of the body and are drilled at an angle of degrees or less to a horizontal line. The lowermost holes B of the pattern are also set- 90 degrees apart, centrally between the holes A and are drilled practically hori- Zontal. A row of holes C below holes B extend horizontally about the head, so as to sprinkle on a circular line D some distance inwardly of the boundary of the area. The intermediate holes in the pattern lie in symmetrical curved lines between the holes A and B. It will therefore be seen that the water issuing through the holes A will have a greater range than that issuing from the holes B. The sprinkler is therefore set in the area E to be sprinkled so that the water from the holes A. will be directed to the corners of the area (which are farthest from the sprinkler), while the water from the holes B falls on the boundary line F of the area closest to the sprinkler or centrally between the corners. The intermediate sprinkler holes in the pattern between the holes A and B are so disposed that the water therefrom will fall on the boundary lines of the area intermediate the corners. The re This causes the water as it mainder of the holes 8 between the pattern holes and the lowermost holes C are disposed so as to water the area between the boundary lines and the line D. This arrangement of the pattern holes insures a very efficient utilization of the sprays of water, since said sprays are not thrown so high in the air and there is therefore less chance of the pattern formed on the ground being disturbed by wind action.
In order to sprinkle the area between the line D and the sprinkler and which is not covered by the holes 8, a whirling-spray nozzle 9 of standard character is adjustably or fixedly screwed into the top of the head 4. This nozzle as shown includes a hollow structure set into the head with top and bottom openings G, and intermediately disposed water-clefiecting passage means H to cause the-water entering the nozzle through the lower opening to be whirled about so that it will issue from the top opening in the form of a substantially flat whirling spray. This nozzle will therefore throw a stream of water outwardly and laterally from the head, without any appreciable upward throw, all around the head to a sufficient distance therefrom to cover the area between the sprinkler and the inner boundary D of that portion of the area watered from the lowermost holes 8, as above stated. The water falling from the central nozzle cuts through the streams from the holes 8, and breaks up said streams into the form of fine sprays.
From the foregoing description it will be readily seen that I have produced such a device as substantially fulfills the objects of the invention as set forth herein.
IVhile this specification sets forth in detail the present and preferred construction of the'device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.
plane, and an additional nozzle member' mounted in the top of the head.
2. A sprinkler including a substantially semispherical head having holes drilled therein radial with the center thereof and forming a. four-sided pattern about the head; the uppermost holes being 90 degrees apart circumferentially and drilled at an angle not greater than 45 degrees relative to a horizontal plane and the lowermost holes being likewise 90 degrees apart centrally between the upper holes but lving in a substantially horizontal plane, the holes in the pattern intermediate said upper and lower holes lying in a circumferential line to cause water thrown from said holes to fall on the ground in a straight line between the points of contact of the water from the adjacent inner and outer holes with the ground.
3. In a sprinkler, a hollow head, a boss depending from the bottom thereof, a substantially cone-shaped screen disposed inside the head and projecting upwardly from the bottom thereof adjacent the sides, a water control member connected to the boss and projecting upwardly into the head inside the screen, said member having lateral openings inwardly of the head. i
4. A sprinkler including a substantially semispherical hollow head having holes drilled therein in the form of a pattern of predetermined form; all said holes being radial with the center of the head and disposed below an angle of 45 to a horizontal plane.
In testimony whereof I afix my signature.
