Description

Oct. 30, 1934. J F. MORAN INTERNAL SPRAY NOZZLE Filed March 24, 1935 INVENTOR Joseph F Moran.
ATTORNEY Patented Oct. 30, 1934 UNITED STATES PATENT OFFICE INTERNAL SPRAY NOZZLE Application March 24, 1933, Serial No. 662,449
4 Claims. (01. 128-'239) This invention relates to spray nozzles, and more particularly to a nozzle adapted to produce a gentle wide angle spray douche for internal use.
5 One object of this invention is to provide a spray nozzle of the above nature which may be readily attached to the end of a rubber tube connected to a hot water bag, syringe bulb, or the like.
A further object is to provide a spray nozzle of the above nature in which the whirling spray will tend to assume the shape of a bulb, at first spreading outwardly and then converging inwardly to a nodal point.
A further object is to provide a device of this nature which will be simple in construction, inexpensive to manufacture, easy to apply and manipulate, compact, and very eflicient and durable in use.
throughout the several views, the numeral 10 indicates a douche spray nozzle consisting essentially of three parts, a cup 11, an end cap 12, and a rivet member 13.
The cup 11 is provided with a cylindrical section 14 having an open end which is adapted to have a substantially tight fit within the end of a rubber tube 15, shown in dotted outline in Fig. 1. The closed end of the cup 11 includes an outwardly extending annular bead 16 and a depressed central inverted dome 1'7, as best shown in Fig. 2. The dome 17 is provided with a plurality of angular cupped depressions 18 (four in this instance) struck up from the metal of said dome in such a manner as to provide an equal number of slits 19 in said metal.
In order to form a chamber to cause the liquid flowing through the nozzle to emerge therefrom with a swirling motion, the cap 12 is secured to the cup 11, as by having its rim 18a soldered to the forward surface of the bead 16.
With these and other objects in view there- The cap 12 is preferably made convex outwardly and is pierced with a central discharge aperture 21.
The rivet 13 is supported with its axis in alinement with the cylindrical section 14 and the discharge aperture 21 by providing a reduced rear end section 22 which is inserted through an aperture 23 in the apex of the dome 17 and headed over the rear side thereof. The forward free end of the rivet 13 terminated in a circular flattened head 24 which is spaced 2. short distance from the outlet aperture 21. The head 24 is slightly smaller than the aperture 21, and serves as a baffle plate form causing the liquid to be discharged from said aperture at a wide angle, such as 45 degrees, from the axis of the nozzle (see Fig. 1).
Operation In operation, liquid will be supplied under pressure from the tube 15 to the cylindrical part 14 of the cup 11. It will then be caused to pass through the slits 19 and be angularly deflected in the chamber 20 by reason of the cupped depressions 18 in such a manner as to set up a rapid swirling motion within said chamber 20. The liquid will then pass out through the discharge aperture 21 in a wide annular stream making an angle of substantially 45 degrees with the axis of the nozzle.
A bulb-like hollow continuous sheet of rapidly whirling liquid will be thus produced as indicated by the numeral 25 in Fig. l, and the liquid of said sheet will rapidly twist around the axis and, if unimpeded, converge inwardly to form a node 26. As the liquid continues its forward motion, it will again spread out, and as it loses energy will scatter in all directions in a broken spray.
It has been found by experiment that the size of the bulb-like sheet 25 depends to some extent upon the temperature, viscosity and surface tension of the liquid, as Well as the pressure applied thereto.
While there has been disclosed in this specification one form in which the invention may be embodied, it is to be understood that this form is shown for the purpose of illustration only, and that the invention is not to be limited to the specific disclosure but may be modified and embodied in various other forms without departing from its spirit. In short, the invention includes all the modifications and embodiments coming within the scope of the following claims.
Having thus fully described the invention,
outwardly from and then return ir iwarrdly toward the axis of said nozzle, the 'axiso'f said bathe passing through said discharge aperture. 2. In a douche nozzle for producing a spray, a cupped shell open at oneuendr for receiving a supply of liquid under pressure, said shell having at its closed end an expanded'hollow bead and a depressed inverted perforated dome.

3. In a douche nozzle for producing a whirling spray, a cupped shell open at one end for receiving a supply of liquid under pressure, said shell having at its closed end an expanded hollow bead and a depressed inverted perforated dome integral with said bead, said dome havinginclined apertures for whirling the liquid passing therethrough,; an outwardly convexed apertured discharge cap secured at its periphery to saidbe ad for providing a swirling chamber between said cap and said dome, and a headed member secured to said dome and located in said s'wirling charnber to form a baffle to cause the I liquidto be. discharged therefrom in a wide continuous stream and to thereafter converge to a nodalpoint, the aperture in said cap being centralized.
4.*In-ad0uche nozzle for producing a whirling --spr,ay,1a tubular shell having an inlet at one end for receiving a supply of liquid under pressure, a perforated water-swirling. diaphragm in said shelL an outwardly convex cap for closing the discharge end of said shell, said cap having a central aperture, and a rivet secured to the center of said diaphragm with. its head spaced from said cap to form a bafile to spread the water passing out through said aperture.
