Description

Patented July 28, 1931 JOSEPH eroanmo, or wnsr mmcx; new YORK- srmx NOZZLE Application filed February 6,1931.v Serial No. 513,996.
My invention relates to a nozzle for spraying more or less heavy liquids, such as asphalt, macadam, tar, 110 penetrating oil, or the like. 1
An im ortant object of the invention is i to provi e a nozzle of the above-mentioned character which will operate in connection with a low pressure, and will produce a whirling spray of the discharging heavy liquid, whereby the same may be uniformly distributed upon a relatively large area of a road-bed, or the like.
A further object of the invention is to provide a nozzle of the above-mentioned char- '1'5' actor, which is readily adjustable for pro- .ducing whirling sprays of different diameters.
A further object of the invention is to provide a nozzle of the above-mentioned character, the parts of which may be readily separated, for cleaning, or the like.
A further object of the invention is to provide a device of the above-mentioned character, which is extremely simple in construction, strong, durable, and will produce a whirling spray, without the employment of movable parts. 7
Other objects and advantages of the invention will be apparent during the course of the following descri tion. 7 In the accompanying rawings, forming a part of this specification, and in which like numerals are employed to designate corresponding parts throughout the same,
Figure 1 is a side elevation of the nozzle embodying my invention,
Figure 2 is a central vertical longitudinal section through the same, F-gure 3 is a' front end nozzle,
Figure 4 is nozzle.
Figur'5 is a side elevation of the removable. spreader stem, 1 Figure 6 is a rear end elevation of the same, and v Figure 7 is a section taken on the curved 1ine'77 of Figure 4.
In the drawings, wherein for the purpose of illustration is shown a preferred embodielevation of the a rear end elevation of the ment of my invention, the numeral 10 designates the body portion of the nozzle, which is preferably .cylindrical. This body portion includes a rear solid portion 11, having longitudinal ports or openings 12, formed or drilled therein. The ports 12 are arranged in an annular group, Figure 4, and these ports are longitudinally inclined in a circumferential direction, preferably at an angle of about 1'6-degree's from the longitudinal axis of the body ortion. .As stated,
the ports 12 are circum erentially inclined,
but do not converge or diverge forwardly,
I and their sides are, therefore, parallel with the side of the body portion.
The body portion includes a conveying chamber 13, preferably converging forwardly and discharging into a forward mouth 14, which flares forwardly. The various parts of the body portion are, preferab lIy, formed as a casting.
he portion 11 is provided centrally thereof with a longitudinal cylindrical opening 15, leading, at its rear end, into a recess 16, affording a shoulder 17, and at its forward end into a recess 18, affording a shoul- .der 19. The longitudinal opening 15 is surrounded by the annular group of ports 12, and is concentric with relation thereto.
. The numeral 20 designates a spreader stem, extending longitudinally through the conveying chamber 13, and concentric with relation thereto. This stem is provided with an enlargement 21, to. enter the recess 18, and to engage against the shoulder 19, 35
and the stem is further provided with a re-. duced extension 22, to enter the opening 15. This reduced extension is provided with a longitudinal screw-threaded opening 23, receiving a clamping screw 26, having a head 27, inserted within the recess 16, and engaging against the shoulder 17 The enlargement 21 carries a pin or lug 28, rigidly attached thereto, to enter a recess or note 29, formed in the portion 11, to prevent 98 turning movement of the spreader stem. It is, thus, seen that the spreader stem may be securely clamped to the portion 11, and may be removed therefrom by manipulation of the screw 26, for cleaning purposes. 100
- spreader stem and may be locked thereto in a selected adjusted position by means of a clamping screw 34, operating within a longitudinal screw-threaded opening 35, formed in the spreader stem 20.' This screw carries a head 36, arrangedv within the recess 32, and engaging the shoulder 33. The spreader is provided, at its forward end, with openings or recesses 38, for receiving parts of a tool, for turning the same, as shown. The spreader30 has a rear conical face 39, which spreads or increases in diameter forwardly and thisface is arranged in suitably spaced relation from the flaring mouth 14, and extends across the bore of" the mouth, preferably, projecting slightly radially beyond such bore.
The operation of the nozzle is as follows:
As before stated, the nozzle is particularly well adapted to be used in connection with heavy liquids, such as are applied to roads. The nozzle may be suitably connected with a wheeled tank, traveling upon the road. The heavy 1i uid is fed to and through the nozzle, preferaldly, at a low pressure of from 15 to 20 pounds to the square inch. The liquid first passes through the circumferentially inclined relatively long ports 12, and is guided thereby into the conveying chamber 13. Due to the circumferential inclination of the annular set of ports 12, the heavy liquid is given a rotary movement about the stem 20, as anaxis, while it is gradually reduced in cross-sectional area while approaching the forward end of the chamber 13. When the rotating liquid reaches the mouth 14, its rotation continues and its cross-sectional area gradually increases as it approaches the flaring surface sult that when the liquid discharges past 39, of the spreader. The rotating liquid, therefore, strikes the orwardly flaring spreader at somewhat a tangent, as distinguished from an axial contact, with the rethe spreader, it is in the form of a whirling I spray- This whirling spra may have a large diameter, and it is ound that the liquid will be uniformly sprayed upon the road. The fineness of the spray and its diameter are regulated by adjusting the spreader 30 toward or from the mouth 14.
It is obvious that the spreader stem may be readily separated from the portion 11, and the spreader 30 from the spreader stem, so that all parts of the nozzle may be properly cleaned, which is important, due to the character of the heavy liquids sprayed.
Particular attention is called to the fact that the whirling spray is reduced by coacting elements, all of which are relatively stationary, thus eliminating the necessity of movable parts.
It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to, without departing from the spirit of my invention, or the scope of the subjoined claims.
Having thus described my invention, what I claim is:
1. A nozzle for spraying relatively heavy liquids, comprising a body portion having a solid portion, said solid portionhaving an annular set of longitudinal ports which are circumferentially inclined, said body portion including a conveying chamber arranged at the forward end of the solid portion, the inner wall of the conveying chamber converging forwardly and the longitudinal ports leading into the conveying chamber adjacent to the wall of the same, said body portion having a forwardly flaring mouth at the forward reduced end of the conveying chamber, a spreader stem extending through the chamber, and carrie d as -by the solid portion and surrounded by the 2. A nozzle for spraying relatively heavy I liquids, comprising a body portion having a solid portion, said solid portion having an annular set of longitudinal ports which are circumferentially inclined, said body portion including a chamber arranged at the forward ends of said ports, a spreader stem extending through the chamber and attached to the solid portion, and a forwardly flaring spreader carried by the spreader stem and arranged near the forward outlet end of the chamber.
3. A nozzle for spraying relatively heavy liquids, comprising a body portion having asolid rear portion which has an annular set of longitudinal ports which are circumferentially inclined, said solid portion also having a central longitudinal opening surrounded by said ports, said body portion including a chamber arranged at the forward ends of said ports and provided with a forwardly flaring mouth, a stem extending JOSEPH GIORDANO.
