.SPRAY NOZZLE,

Application led Februaryv 16, 19,24. i Serial No. 693,218.,

Be itknown that I, CAssiUs M. CLAY B Amn, a' citizen of the United States .of America, and a resident of Chicago, county Aof Cook, and State of Illinois, have invented la new and useful Improvement 1n Spray Nozzles, of which .the following is a specification.

This invention relates' to garden hosev provided with .spray nozzles secured thereto at intervals along its length so that the ordi` nary flexible garden hose may be employed for sprinkling a relatively large area.

' The present application for patent is a.

continuation in part of the previously led application No. 516,726, filed November 21,

The object of the invention is to provide a Vspray nozzle having a threaded conical nip-r ple with a small sharpened'point at the endy of the nipple so that the nozzle may be forced into the side of'a rubber hose .of

standard construction without injury to the line 2 2 of Fig. 1.v

fabric. It is also a purpose of the invention to provide a construction which will insure a permanently .water-tight connection and v prevent access of moistureto the fabric of the hose. v

The objects of the invention are accomplished by the construction illustratedin the drawing, in which :-7

Figure 1 is a plan view of a fragment of garden hose equipped with one of the spray` nozzles. v l.

Fig. 2 is a sectional viewV takenv alor/1g the Fig. 3 isa side view of the spra nozzle. Fig. 4 is another side view of t e spray nozzle taken at'. right angles to the view shown in Fig. 3.

/5 shows a slightly modified construc-V i tion in which the sharpened end of the threaded nipple is not beveled off at one side as shown in the remaining figures.

The improved spraying device may be ap plied to a garden hose by hand or with the use of pliers simply by forcing and 'screwing the sharpened threaded nippleof the deylill vice through the wall .of the hose. Without preliminary puncturing of the hose, the shape of nipple permits it to be screwed through rubber and fabric so as to spread fabric without injuring same. The'fabric used in garden hose is frequently of very open mesh, and, therefore, the spray device when applied to the hose, merely spreads the meshes of the fabric without cutting it. The` conical nipple also wedges the rubber body part of the,hose`outwardly,`and the rubber hning resiliently engages the nipple, preventing 'water from traveling upwardly f' along the exterior of the nipple tothe fab` ric.. The fabric should be kept dry since when water is permitted to travel along the fabric, the hose deteriorates faster than ordinarily.l l

The drawing shows a flexible garden hose '1 formed as usual of a series of rubbertubes 2, separated by the fabric tubes 3. The spray nozzle includes a head 4 slotted at 5 for, receiving a screw driver, if' desired, and having a concave recess 6 in its side above the circular flange 7. l' The tapered threaded nipple or shank'8 is provided with an axial perforation 9 for conducting and projecting lwater from the hose against the concave sur-A face of the recess v6, -this surface serving to "spread thev jet of water. The end 10 of the conical nipple is sharpened, and to further bring it to a point, the end of the nipple may be beveled off as at 11. 'l a yIn applying the spray nozzles to the garden hose, it is merely necessary to screw them down tightly yinto position, the tapered nipple serving to spread the fabric and the rubber of the hose without much injury thereto. l

The nozzle nipples may be dipped in lrubber cement'before applying the nozzles to the hose, but this is not essential for a watertight connection, since the ,conicall nipples .merely l s read the rubber outwardly and downwar ly, resulting in the rubber becoming compressed around the nipples.

Iclaim: .Y .v 1. A spray nozzle ofthe class described comprising4 a body having a head and a conif cal'threaded hollow nipple sharpened at its en 2. The combination with a arden hose of a spray nozzle comprising a ody having'a head, and a conical threaded hollow nipple sharpened at its end and extending through the side of the hose.

3. A spray nozzle ofthe class described I' cal threaded hollow nipple sharpened at its l i comprising a body having a head and a coniend, said head having a spreading and deflecting surface in position to be engaged by fluid passingthrough said nipple.

4. -A spray nozzle of the class described comprising a bod having a head and a conical threaded holfbw nipple,- said head having a spreudingund deecting surface in position to be engaged by fiuid passing through said nippie, and the end of Suid nipplcbeing beveled 0E at one side to bring it to :L point.

5. The combination with a garden hoseof a spray nozzle, comprising a head and a threaded hollow nipple sharpened at its end wherebyv thenipple may be screwedthrough the rubber und fabric of the hose so as to spread the fabric without injuring the saine. 10
