Application January 16,

1 Claim.

This invention relates to sprinklers of the general character embodied in my United States Patent No. 1,766,514, issued June 24, 1930, and embodying means whereby an area bordered by straight lines can be uniformly sprinkled by the automatic regulation of theflow of water from the sprinkler during the operation thereof.

It is the purpose of the present invention to embody the principle `of the above described sprinkler in an extremely simple structure capable of being inexpensively manufactured and of functioning at maximum efliciency, to effect the uniform sprinkling of an area bordered by straight lines, all with minimum wear on the working parts of the sprinkler so as to insure long life of the latter.

Only one form of the invention will be described, following which its novel features will be pointed out in claim.

In the accompanying drawing Figure l is a plan View of the sprinkler with portions broken away to expose internal construction;

Figure 2 is a vertical sectional view taken on the line 2-2 of Figure 1, and looking in the direction of the arrows;

Figure 3 is a plan View of the mounting or stationary portion of thesprinkler.

Similar reference characters designate similar parts in each of the several views.

Referring specifically to the drawing, this invention comprises a mounting or base member in the form of a cylindrically shaped tubular body I0 internally threaded at one end as indicated at I I so as to enable the body to be screwed onto a pipe I2 which is adapted to be supported in any suitable manner to occupy a vertical position and to be connected to a source of water supply under pressure. The body I0 is enlarged in diameter at its other end to provide an external annular shoulder I3, and said other end ,of the body is closed by a wall I4 which is transversely disposed with respect to the axis ofthe body. In the present instance the wall I4 is illustrated as deining a plane surface in cross section, although it is to be understood that the wall can be either convex, concave or conical in cross section without departing from the spirit of this invention,V

The pipe I2 defines a waterrinlet to the body, and the water supplied to the body is adapted to 'discharge therefrom through outlets I5 formed in the wall I4. These outlets I5 which are in the form of square openings, are four in number, and are equally spaced about the axis of'the body, two diagonally opposite corners of each opening 1933, serial No. 652,069

being radially arranged with respect to the axis of the body vas clearly shown in Figure 3.

On the mounting or base member defined by the body I 0 is supported a rotor comprising a flat plate IB having a hub II and three arms I 8 equally spaced circumferentially and radiating from the hub. From the hub an annular flange I 9 pro-4 jects laterally and 'receives the enlarged end of the body I0, with the wall I4 of the latter abutting the hub. The hub in the present instance defines a plane surface in cross section to correspond with the cross sectional contour of the wall I 4, and it will be understood that should vthe Wall I4 be convex, concave or conical in cross section, that the wall formed by the hub will be complementary thereto.

The rotor also includes a second plate 20 having a hub 2| and three arms 22 which are respectively crimped about the `edges of the hub I'I and arms I8 of the plate I6, as indicated in Figure 2. The arms 22 are concavo-c'onvex in cross section for coaction with the, arms I8 in defining water passages 24,` the inner ends of which communicate with inlets 25 formed in the h ub I'I of the plate I6. lThe inlets 25 which are in the form of squareopenings corresponding in size to the outlets I5 are three in number and are equally spaced about the -axis of the body I0, two diagonally opposite corners of each opening being radially arranged with respect to the axis of the body as clearly shown in Figure 1. At the outer ends of the arms 22 in comvassumed that water under pressure is being supplied to the pipe I2. It will be noted that the outlets l5 and inlets 25 of the mounting and rotor, respectively, are so disposed relative to each other that each of the inlets will at all times overlap at least a portion of one of the outlets, and that as this overlapped relation of the outlets and inlets Varies from a predetermined minimum to a predetermined maximum, and then vice versa during rotation of the rotor, that water will continuously discharge from the ports 2B in constantly varying volumes, such as to 'eiect the uniform sprinkling of a square area inthe center of which the sprinkler is located.

' inlet pipe and having a circular enlarged portion providing anv external annular shoulder, said circular enlarged portion being terminated by a transversely disposed Wall, said Wall having a mounted for rotary movement on said Wall and having a series of substantially square apertures so arranged With respect to said wall apertures that during rotation of the plate each of the plate apertures will overlap one of the Wall apertures from a minimum to a maximum and then vice versa, a plurality of distributing arms carried by the plate, there being one thereof for each plate aperture, a hub Yrotatably tted over said circular enlarged portion of said tubular body and attached to said plate, and means oooperating with said annular shoulder and with the hub for maintaining the parts in operating relationship.
