Specification of Letters Patent'i 'Patented' S01; 28, 1909- Application filed October 2, 1908. Serial No. 455,833.

To all whom it may concern:

Be it known that I, PHILIP A. Bin-111s, a citizen of the -.Unite(l States. residing at Ashland. in the county of Ashland and State of Ohio. have invented certain new and mean Improvements in Spray-Nozzles. of which the following is a specification. ret- -renre being had therein'to the accompanying drawings. l

My invention relates to spray nozzles. and has for its object. the production of a nozzle of this character in which the packing will be so arranged. between the body of the nozzle and the cap therefor, that it will be subjected to the pressure of theliuid within the nozzle and will not be liable to be blown out or to be disarranged. Further, to pro vide such a nozzle with n Hills for controlling the discharge in such a manner as to cause the same to form aspreading or um brella shaped spray; andv further; to pro ride a nozzle of this character having a dis gorger and provided with positive means for limiting the stroke of that disgorger, thus enabling a short, qulck stroke to be imparted to the disgorger to freethe discharge aperture from foreign matter.

d'it'h these ob ects in view'my invention consists in certain novel features of construction and in certain combinations and arrangements of parts hereinafter to be described, and then more particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a nozzle embodying my invention: Fig. 2 is a front elevation of the same. with the cap removed; Fig. 3 is an enlarged longitudinal, sectional view, taken tl'irough such a nozzle; Fig. 4 is a front elevation oil? a modified form of the nozzle, with the cap removed; and Fig. is a longitudinal. sectional View taken cent -'ally of a nozzle. such as shown in Fig. l.

In Figs. 1, 2 and 3 I have illustrated one embodiment of my invention andhave shown the same as comprising a cylindrical body portion 1 ha ving a screw-threaded side wall 2 and pr vided with an inlet which, in the present. instance, comprises a'nipple 3 extending outwardly from the rear wall. of the body portion 1 and provided'with a stufiing box 4: within which is mounted an inlet pipe 5 having a coupling 6 for securing the same to a supply pipe. The-pipe 5 is slida-bly mounted in the nipple 3, has its inner end closethas shown at 7, and is provided with-outlet apertures 8 arranged near the rear wall of the cylindrical body portion. ii cap 9 is reinovably mounted on that end of the cylimlrical body portionopposite,

the inlet opening, preferably by 'providii'ig the same with an annular scrmv-thremlml flange 10 forming a side wall adapted to cooperate with the screw-threaded side wall of the body portion. This cap is provided with a centrally arranged outlet. opening it through which the tluid is discharged. The body portlon 1 and cap 9 form between them a chamber 12, within which is mounted a disk 18 having one or more inclined apertures 14;- adapted to receivev the water from the apertures S of the inlet pipe 5 and discharge the same into the chamber 12 with a whirling motion. This disk may be supported in the chamber in any suitable man" nor, but, in the present instance, I have shown the same as having a central screwthreaded aperture adapted to engage the screw-threaded inner endiof the inlet pipe 5. In the present form of the device, this disk 13 lies normally'in a position close to the rear wall'of the body portion 1 and I have here shown the rear wall as cut away, as shown at 15, at a point adjacent to the apertures 8 in the inlet pipe 5, thus enabling the fluid to be discharged from the inlet pipe through the discharge apertures'kl while the outer edge of the disk 13 rests upon the rear wall of the body portion 1. A conical projection 16 is ar "anged centrally of the disk 13 on that side thereof adjacent to the discharge aperture 11 in theeap 9 and so affects the movement of the fluid within the chamber 12 that the fluid will be discharged from the nozzle in the fOIIH Of a-spreading or umbrella shaped spray. In the present instance I have shown this projection as formed integral with the inner closed end of the inlet pipe 5 and as having the form of a frustum ot' a cone. Mounted on the inner end of the projection 16 and in alinement with the discharge aperture 11 is a pin 17 of a length. substantially equal to the length of said discharge aperture. Thus, it will be seen that by the movement of the inlet pipe '5 relatively to the body portion 1, the pin the nozzle is c be apparent that the "inner end of the projection 16 face thereof is placed against the limb of a move the body tree and the handle pressed forward to move the inlet pipe and the disgorger" or pin 17 toward the aperture 11. As soon as the nozzle is released from the limb or other-objectagainst which it has been pressed, the pressure of the fluid within the chamber 12 will portion of the nozzle away from .the. disgorger and into its operative 9 water with an annular recess o facap curing the same to a supply pipe.

packing parts of the nozzle.

faces of position. In order to provide a seat for the g which is employed to render the between the body portion 1 and the cap tight, I prefer to provide the body portion 1 with a seat or recess in which the packing is disposed. In the present instance I have shownthe body portion 1 as provided with 'an annular. flange 18 extending outwardly therefrom and having that face which lies adjacent to the screw-threaded side wall 2 of the body portion provided 19 adapted to receive oacking 20. This recess 19 is preferably of a width slightly greater than the thickness of the inner. edge of the side wall 10 of the joint cap 9, which edge is adapted to engage the packin g which is supported in the recess v Thus,

it will be seen that the packing is placed at such a pint that it is not subjected to the pressure 0 the water within the chamber 12 and isnot liable to be blown out or to become disarranged, but will maintain at all times a water-tight joint between the two In Figs. 4 and 5 of the drawings I have. illustrated another form of nozzle, which is not provided with a disgorger. In this form of the device the body portion 21 is provided with a cylindrical side wall 22 adapted to codperate with the cylindrical side wall 23 24 having a discharge aperture 25 arranged centrally thereof, the adjacent the

side walls

22 and 23 of the body portion and cap, respectively, being screwthreaded to permit of the ready separation or adjustment of these parts. The body portion is also provided with a centrally arranged inlet 26 having a coupling 27 for se- An annular flange 28 extends about the rearportion of the body portion 21 and is provided on the face thereof adjacent the cap 24 with an annular recess 29 adapted to receive a packing 30, the arrangement of the recess 1 scribed above m connection with Figs. 1 to 3.

A disk or partition 31 isa'r'riounted in thefrom the inlet 26=and is provided chamber formed between the body portion 21 v I and cap 24 and: as here shown, is permaa nently secured to the cylindrical side wall of the body portion at a point some distance with an inclined aperture 32 adapted .to discharge the fluid into that portion of the chamber lying whirling motion. This disk is preferably between the disk 31 and the. cap'24 with a provided with a centrally arranged conical rojection, as shown at 33, the'apex of which is in substantial alineme'nt with the discharge aperture 25 of the cap 24 and serves to control the discharge of the fluid through that opening.

The operation of the device will be apparent from the foregoing. description and it will be seen that 'I- have provided a-nozzle of this character which the packing is so arranged that it is not liable to be blown out or to become disarranged, thus maintaining at all times a water-tight joint between the body portion and the cap of the nozzle.

Further, it will be seen that I have provided means for so controlling the discharge of the fluid from the nozzle as to cause the same to be discharged in the form of a spreading or umbrella shaped spray; and that I have provided a nozzle with a disgorger having a positive stop for limiting the movement thereof and thus enabling the same to be actuated with a quick, short, stroke, materially facilitating the operation thereof.

I wish it to be understood that I do not desire .to be limited to the details of construction shown and described, for obvious modi-.

fications will occurto a person skilled in the art.

Having thus fully described my invention, what I claim as new and desire to. secure by Letters Patent, is
