2 Claims.
This invention relates .to nozzles for spraying liquids, and the principal object thereof is to provide a nozzle particularly adapted for use in connection with oil burners, but may be also utilized with spray guns, atomizers or analogous devices.
Another object of the invention is to provide a nozzle for use in connection with oil burners operating on either high or low pressures, said nozzle being so constructed that it will produce maximum heat per oil consumption. I
A further object is 'toprovide a nozzle of the above type having an orifice which may be conical or cylindrical and provided with spiral flutes to give the oil issuing from the orifice a whirling effect to produce a very fine oil mist; the use of the spiral fiutes minimizing possibility that the orifice will become clogged or carbonized,
apart and cleaned when necessary; also to provide a nozzle which may have a brass screen of very fine wire mesh therein soldered to a copper washer, which washer serves as a gasket between certain of the nozzle sections to preventleakage of oil; also to provide a removable threaded tip member for the nozzle; formed of two separable members threaded together and formed so asto provide a small oil chamber opposite the orifice of the tip into which the oil collects before passing therethrough, the tip member being provided to adopt and use the same'; and will summarize in the claims the novel features of construction, and novel combinations of parts, for which protection is desired.
In said drawing: v
Fig. 1 is an elevation of the complete nozzle.
Fig. 2 .is an enlarged vertical section therethrough showing a filter screen housed within the nozzle body. v
Fig. 3 is a view similar to Fig. Z/but showing the screen omitted.
and thus obviating the necessity of utilizing air with a central bore communicating with the nozzle body and further provided with one or more small angularly disposed bores extending through the tip from the central bore to the oil chamber whereby the size of the latter bores will determine'the grade of fuel oil to be used with the nozzle, a heavy grade of fuel oil being ,used when the angularly disposed bores are of relatively large diameter, and a light grade oil being used when the bores are small.
- Other minor objects will be hereinafteriset forth.
I will explain the invention with reference to the accompanying drawing which illustrates one practical embodiment thereof .to enable others tubular form externally threaded at its lower end la, and having a non-circular-outer wall portion lb intermediate its ends to receive a wrench to facilitate assembly of the sections. The end of body I opposite from the threads la is provided with internal threads lc for the reception of the removable tip section, hereinafter described.
On the threaded portion Ia of body I is a coupling section 2 having a non-circular outer wall and having an internally threaded recess 2a in its upper end receiving the external threads la of body section I. Section 2 has a reduced extension 2b;at' its lower end provided with a central bore 20 communicating with recess 2a, .the extension 2b being externally threaded as at 2d,
whereby the same may be threaded onto any oil burner or the like by selection of a coupling section 2 having the proper size extension 21).
As shown in Fig. 2, extending upwardly within body section I is a tubular screen 3 of somewhat smaller diameter than the bore of the section,
terminating below the upper end of said section, screen 3 being preferably made of brass wire of fine mesh, and the upper end of said screen being provided with an end wall 3a of same material as the body of the screen, whereby oil or other liquid together, gasket 4 preventing leakage 011 befrom the lower end to a point substantially at the upper end thereof. The upper end of member 5 is conically tapered as at 50, and the upper end of bore 5a extends into said conical portion and terminates therein. Extending through the conical portion 50 substantially normal to the outer wall thereof is an outwardly flaring series 01' bores 5d whereby the oil or other liquid from bore 5a will be caused to split up and pass out of the member 5 through the series of bores 5d. The upper tip of member 5 above the bores 5d is truncated or cut oil as at 5e for the purpose hereinafter set forth. For heavy grade oil, bores 5d of relatively large size will be required, whereas for light oil smaller bores will be required, the size of the bores determining the grade of oil or other liquid to be used with the nozzle. Instead of utilizing the series of bores 5d in member 5, the same results may be obtained by utilizing only one large bore in the tip; however the provision of the series of bores 5di minimizes the chances that the tip will become plugged or clogged.
On the axis of cap member 6 at the upper end thereof is an orifice 66, preferably of conical shapecontracting towards its upper end into a substantially small opening as shown more particularly in Fig. 5. In the Walls of orifice 6e are spiral fiutings 6) adapted to impart a whirling effect to the oil or other liquid passing through the orifice, to break same up into a very flno mist. By utilizing the spiral rioting if in the nozzle orifice, the nozzle is not likely to clog or carbonize; and use of such flutings obviates the necessity for utilizing air or steam to break up the oil as it leaves the orifice, and thus results in a construction which is inexpensive to manufacture and operate. If desired however. the flutes 6f may be straight as at lg (Fig. 6) instead of spiral; also the orifice 5e may be cylindrical as in Fig. 6 instead of conical as in Fig. 5. The size of orifice 6e determines the size and characteristic of the flame issuing from thenozzle.
By the above construction, a nozzle is provided in which the sections and members may be readily separated for the purpose of cleaning in event any parts should become clogged or carbonized; also a nozzle that will operate at either high or low oil pressures, and one that has been found to work satisfactory with heavy grade fuel oil at very low pressures in cold weather; also a nozzle that operates efliciently on a minimum rate of oil consumption. The nozzle may not only be used in connection with oil burners, but may also be used in connection with spray guns, atomizer-s. or other analogous devices.
I claim:
1. In a nozzle, a tip comprising a cap member adapted to be connected to a liquid supply,
said cap having a conical bore contracting into a conical recess terminating in an orifice; and a member within the bore having its inner end correspondingly conically formed and contact-.
ing with the conical walls of the bore in the cap while spaced from the conical walls of said recess, the inner tip of said member terminating .a member within the bore having its inner end correspondingly conically formed and contacting with the conical walls of the bore in the cap while spaced from the conical walls of said re-" cess, the inner tip 01 said member being truncated and terminating within the recess opposite the orifice, said member having a bore open at its outer end and closed at its inner end, and having a series of radially disposed ducts therethrough adjacent the inner end of the bore discharging directly into the conical recess.
