8 Claims,
An object of the invention is to provide a nozzle which will notcorrode or erode and which will at all times discharge a jet of fluid in a predetermined manner.
Another object of the invention is to provide a nozzle having an orifice formed in a hard stone, such as a diamond, a sapphire, agate or ruby, which will not corrode or erode with heat, or under the influence of acids and other fluids flowing through the nozzle, and to provide a distributor with a hard stone such as a sapphire with a slot or slots leading to the orifices.
A further object of the invention is to provide a nozzle which is particularly adapted for use on fuel burnersand which will safely and accurately discharge a jet of combustible fuel in a predetermined manner under various conditions and for a long period of time.
Additional objects of the invention will. appear in the following specification in which the preferred form of the invention is described.
In the drawing similar reference characters refer to similar parts in all the views, of which- Figure 1 is a sectional elevation showing a nozzle provided with the improvement which is the subject matter of this application.
Figure 2 is an inverted plan view of the nozzle as shown in Figure 1;
Figure 3 is a plan view illustrating the nib with the diamond or other hard stone having the discharge orifice; and
Figure 4 is an inverted plan view showing the head on the distributor stem, the head being fashioned from a sapphire or other hard stone.
In oil burners there is very often difiiculty with the nozzle from which a jet of the fuel passes to the fire box because of the-corrosion and erosion of the material adjacent an outlet orifice through which a jet of fuel passes to the fire box. It has been found that when the material of which the nozzle is constructed corrodes or erodes adjacent the orifice, the fuel is not directed properly by the nozzle and that the operation of the oil burner is, therefore, unsatisfactory inasmuch as with which meshes a thread IS on a distributing stem I6. There is asecond casing member I! which is connected with the casing member ID by means of threads l8.
It will be seen that the distributing stem l 6 has a head H] which is manufactured of a hard stone, such as a diamond, a sapphire or agate, this hard stone head 19 having tangential feed slots 20 which serve to feed fuel oil supplied through the pipe I l to the casing member In and through the apertures 2| in the partition l3, the oil passing to the bottom of the casing member I! adjacent .the head 19 and thence through the tangential feed slots 20 to the swirl chamber 22.
In the opening 23 in the bottom of the casing member I! there is disposed a nib 24 which is held in position by the. portions of the casing member I! extending below the nib 24, as .illustrated in Figure 1, there being set in the nib 24 a hard stone 25 which is preferably a bort or other diamond, but it will be understood that a sapphire, agate, ruby or any other incorrodible hard stone may be substituted therefor. As will be seen by referring to Figure 3 of the drawing, the hard stone 25 has irregular sides. This hard stone 25 is, therefore, secured in the nib 24 by casting the nib with the hard stone positioned in the mold and with the outer face of the hard stone exposed, as shown in Figure 1. This hard stone 25 has an orifice 26, the nib 24 having an orifice, the sides of which converge downwardly to the inner walls of the diamond or other hard stone, at its orifice 26 forming a continuation of the orifice at the swirl chamber 22 of the nib 24. The hard stone 25 at the outer side of the orifice 26 has a sharp edge 26 which is preserved during use because of the character of the hard incorrodible stone 25. This is important for any wear, erosion or corrosion of this sharp edge 26' will so enlarge the orifice that it will not properly feed the fluid.
It will be understood that with this construction the orifice 26 of the nozzle will be fashioned of a material which is incorrodible, and which when the nozzle is used in a fuel burner will not corrode, erode or become in any way distorted or shapeless under the heat from. the fire box, or through other causes to which it may be subjected. It will also be understood that the slots 20 will maintain their normal size so that the fuel will be supplied to the slots 20 at all times in the desired manner, the fuel oil then passing from the orifice 26 to the fire box or furnace. It will be understood that while the nozzle which has been described is of particular value in connection with oilburners, it may also be used for a great variety of purposes where it is important that the orifice in the nozzle be made of material which will not corrode or erode, and that the passages leading to the orifice be also constructed of a material which will not corrode or erode.
What is claimed is:
1. A nozzle having a casing with an opening, a nib secured in the opening, a diamond cast in the front face of the nib, the diamond having a jet orifice and the outer face of the diamond being fiat and at a right angle to the axis of the orifice, said orifice converging to an acuteangled edge at said face, the nib having a tapered swirl chamber therein behind the diamond and terminating in said orifice, the rear face of the nib being beveled toward said chamber, and a stem in the casing having a beveled head provided in its face adjacent the nib with tangential feed slots leading to said chamber.
2. In an oil burner atomizer, means for effecting permanencyin quality and quantity of delivery of oil from the atomizer when oil is delivered to the atomizer at high pressure, said means comprising a distributor, a whirling chamber and a head, said head having therein a setting of a substance of the group comprising sapphire, ruby, corundum and diamond with a spray-ejection orifice through said setting, and said atomizer having a whirl-producing duct for admitting oil into the whirling chamber.
3. In an oil burner atomizer, means for effecting permanency in quality and quantity of delivery of oil from the atomizer when oil is de-,
livered to the atomizer at high pressure, said means comprising a distributor, a whirling chamber, and a head, the head having therein a setting of a substance of the group comprising sapphire, ruby, corundum and diamond with a spray-ejection orifice through said setting, said distributor being in relatively fixed contact, with the head around said whirling chamber when in use and having a whirl-producing duct for admitting oil into the whirling chamber.
4. In an oil burner atomizer, means for efiecting permanency in quality and quantity of delivery of oil from the atomizer when oil is delivered to the atomizer at high pressure, said means comprising a distributor, a whirling chamber, and a head, the head having molded therein a setting of a substance of the group comprising sapphire, ruby, corundum and diamond with a spray-ejection orifice through said setting, said distributor being in relatively fixed contact with the head around said whirling chamber when in use and having a whirl-producing duct for admitting oil into the whirling chamber.
