without diminishing its volume as it reaches the ground or plants.

A further object of the invention is to regulate the effective area of the stream of water.

A further object of the invention is to deliver a stream of water to plants or foliage without damaging the plants or foliage or washing away the soil.

A still further object of the invention is to provide means to anchor the device in the ground and prevent rolling.

Other objects will appear as the disclosure progresses. The drawing is merely intended to indicate a possible embodiment of the invention. It is obvious that the actual needs of manufacture may necessitate certain mechanical changes. It is, therefore, not intended to limit the invention to the embodiment illustrated but rather to define such limits in the appended claims.

Fora more general understanding of the invention attention is called to the drawing in which 7 Figure l is an exterior view of the device.

Figure 2 is a longitudinal sectional view thereof.

Figure 3 is a section on line 3-3 of Figure 2.

Figure 4 is an exterior view of a modified form of the invention.

Figure 5 is an exterior View of still another form of the invention.

Figure 6 is a perspective view of the anchoring plate.

Figure 7 is a fragmentary view of the flange for receiving the anchoring plate.

Referring now to the drawing in detail, numeral I designates the body of the casing, 2 the funnel shaped flange and 3 the inlet opening. Extending from the inlet opening and entering the casing is an elongated tube 4. Attached to the inner periphery of the casing by any suitable means are a series of anchoring plates 5 diametrically spaced and extending outwardly of the flange. The center of said anchoring plates are adapted to enter the slots 6 of the flange 2 and provide a means of connecting the flange and body of the device together.

The anchoring plates not only hold the flange and body together but also provide means to anchor the device to the ground and prevent rolling on uneven or sloping ground as the four plates made of relatively thin material will readily enter the ground and keep the device in the position where originally placed.

The operation of the device is as follows: The nozzle is designed to be placed on the ground adjacent the plants to be irrigated with the anchoring plates partly or fully submerged in the ground and the pressure turned on. The water entering the nozzle by the way of the hose 7 and tube 4 will strike the closed end 8 of the device and be forced back against the closed end 9 of the funnel shaped flange 2 and thence out between the space I0 formed'by the said flange and easing I at a greatly reduced pressure. The water will pour over the casing and be spread over a comparatively large area depending of course on the area of the end of the casing. This effective spread of the water can be increased or de- 7 creased by slightly modifying the casing.

For instance, in Figure 4 the device is shown with the walls II and I2 of the flange and casing tapering inwardly towards the end thus reducing the area of the spread of water. pouring off the end of the casing. In Figure 5 the wall 13 of the casing tapers outwardly towards the end thus increasing the area of the spread of water. It will be noted that the slope of the flange M in this modification is opposite the slope of the casing. The purpose of this arrangement is to further decrease the force of the water leaving the device by restricting the opening l5. This arrangement is especially useful where the initial pressure is very high. Otherwise the construction of the modifications shown in Figures 4 and 5 are the same as the preferred form illustrated in Figure 1.

It will thus be seen that I have provided a simple, efficient and scientifically designed pressure reducing nozzle for irrigating farm land. The device will water the plants without splashing and deliver the water very gently to the roots or base of the plants or vegetation.

Having described my invention, I claim:

1. In a device of the class described, a casing closed at the outward end and open at the inner end, a plurality of relatively thin anchoring plates attached to the outer periphery of said casing at its inward end, a funnel shaped element provided with a relatively short skirt portion, said skirt portion being larger in diameter than the i said cylindrical casing and provided with slots, said anchoring plates entering said slots and holding said casing and funnel shaped element in fixed relation to each other, the ends of said anchoring plates extending beyond the diameter of said skirt portion, and an inlet tube fixed to the center of said funnel shaped element.

2. In a device of the class described, a casing closed at the outward end and open at the inner end, a plurality of relatively thin anchoring plates attached to the outer periphery of said casing at its inward end, a funnel shaped element provided with a relatively short skirt portion, said skirt portion being larger in diameter than the said cylindrical casing and engaging said anchoring plates, and an inlet tube fixed to the center of said funnel shaped element.
