Description

Feb. 25, i935. H, E. MENG Zgz SPRINKLER HEAD Filed Sept. 13, 1934 EUU/f riff VL Patented Feb. 25, 1936 UNITED STATES PATENT OFFICE SPRINKLER HEAD corporation of Illinois Application September 13, 1934, Serial No. '743,786

2 Claims.

The invention relates to sprinkler heads of the centrifugal type having a spray chamber circular in cross section and provided with a tangential inlet port or ports and a single axial outlet port 5 at its top. The present invention seeks to provide a sprinkler head of this type arranged to uniformly spray a substantially square surface. The improvement consists in the features hereinafter set forth illustrated in preferred forms in l the accompanying drawing, and more particularly pointed out in the appended claims.

Fig. 1 is a plan view of the sprinkler with the square area covered by the spray therefrom indicated by dot and dash lines.

Fig. 2 is a full sized plan View of one form of the improved sprinkler.

Fig. 3 is a cross section on the line 3-3 of Fig. 2.

Fig. 4 is a detail section on line 4 4 of Fig. 3.

:0 Fig. 5 is a full sized plan view of a slightly modied form.

Fig. 6 is a cross section on the line 6 6 of Fig. 5.

The spray chamber III in the form shown in 5 Figs. 2 and 3, is formed by a plate II constituting its bottom wall and a cup-shaped member constituting its cylindrical side wall I2 and a substantially flat top wall I3. An inlet chamber I4 is formed by a cup-shaped member having 0 a cylindrical side wall I5 and a flat bottom wall I6. 'Ihese parts are preferably formed of sheet metal and the cup-shaped members are provided with outwardly deected flanges II and I8 which embrace the edge of the plate II, one of 5 the flanges being bent over the other as shown to securely connect the sheet metal parts and form a water tight joint.

To mount the sprinkler head on the end of a l pipe I9, the inlet chamber I4 is provided with 3 a nipple 20 suitably secured in an opening in the bottom wall of the chamber, and in the form shown, projecting upwardly into the inlet chamber. The nipple is internally screw threaded to engage the thread on the end of the pipe I9 and 5 is provided as usual with a. suitable seat for a packing washer 2|.

The plate II which forms the top of the inlet chamber I4 and the bottom of the spray chamber I0 is provided adjacent its edge with a circular series of tangential inlet ports 22 formed by cutting slits in the plate and pressing portions of the metal upwardly as indicated in Fig. 4. The spray chamber is provided at its top with an axially disposed four-sided outlet port 23 bounded by an upturned flange or edge wall 24 which is preferably integral with the sheet metal top wall I3 as shown. The edge wall 24 which forms the four-sided outlet port, as most clearly shown in Fig. 2, has sharply rounded corners 25 and sides 26 which are bowed outwardly to a slight extent. 5 It is also noted that the edge wall 24 of the outlet port is vertically disposed and is substantially parallel with the axis of the outlet port. Also, it should be of substantial height. As stated, Figs.

2 and 3 are full sized views of one form of the 10 improved sprinkler head and as indicated in Fig.

3, the edge wall is substantially one-eighth of an inch in height. Also as noted, the corners 25 of the outlet port are sharply rounded and the sides 26 bowed outwardly to a slight extent. In the 15 form shown in Fig. 2, the corners have a radius of about one-eighth of an inch and the side edges have a radius of about one-half inch.

In operation, the spray is delivered from the sprinkler head over a square area 21 indicated in Fig. 1. As there indicated, the corners of the area are in line with the central portions of the side edges of the four-sided port. It has been found that if the sides of the port are straight, instead of being bowed outwardly to a slight extent, the spray will reach the corners of the square area, but will fall short of the side edges thereof.

In the form shown in Figs. 5 and 6 the spray chamber I0 is formed by a sheet metal cone 28 and an upwardly dished sheet metal plate 29 having tangential inlet ports 30 and a depressed central portion 3|. 'Ihe inlet chamber I4' is formed between the plate 29 and the cast metal plate 33 having a depending externally threaded nipple 34. The cone-shaped member 28 is provided with an edge flange 35 which is bent over and pressed against the edges of the plates 29 and 33 to secure the parts together.

In this form the axial outlet port 23 is similar in all respects to that of the form shown in Figs. 2 and 3 except that, since the sprinkler head shown in Figs. 5 and 6 is smaller, the dimensions of the outlet port edge iiange 24 which bounds the outlet port are correspondingly reduced. In this form the height of the edge flange and the radius of the sharply rounded corners is about one-sixteenth of an anch and the radius of the outwardly bowed sides is about ve-sixteenths of an inch. In the form shown in Fig. 3, the plate II is provided with a small central discharge opening 32 in axial alinement with the outlet 23.

Changes may be made in the details set forth without departing from the scope of the invention as defined in the appended claims.
