INJECTOR.
Specification of Letters Patent.
Patented Dec. 8, 1914.
Application filed June 25, 1914. Serial No. 847,269.
To (ZZZ whom it may concern Be it known that I, DAVID \V. PATTON, a citizen of the United States, residing at'Moberly, in the county of Randolph and State of Missouri, have invented certain new and useful Improvements in Injectors; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to improvements in injectors and more particularly to the delivery tubes thereof.
The primary object of the invention is to provide a device of this character so constructed as to reduce the amount of wear upon the tube by the jet of water forced therethrough and to provide means whereby this jet of water may be broken into a fine mist thereby allowing the same to be more readily heated upon entrance to the boiler.
A secondary object of the invention is to make the above set forth improvements without the necessity of altering other parts of the form of injector with which the invention cooperates.
With these objects in view, the invention resides in certain novel features of construction and combination herein described and claimed and shown in the drawings wherein:
Figure 1 is a vertical section through a portion of what is known as a Sellers injector, showing the application of my improved delivery tube thereto; and Fig. 2 is an end view of the tube removed from the injector.
In the accompanying drawings I have shown portions of an injector I which is of common construction being provided with the usual steam and water inlets (not shown) and a water outlet 0. The interior of the casing, directly above the outlet 0, is provided with a threaded bore B in which an externally threaded portion 1 of the delivery tube 2 is located, the threads of the portion 1 engaging the threads of the bore B. In applying my improvements to the deli" ery tube 2, no alteration whatever is made to the exterior thereof. The passageway 3 of said delivery tube, however, is formed of a plurality of bores indicated in the drawings at i, 5, 6 and 7, said bores increasing in diameter from the innermost bore a to the outermost bore 7 while each one of said bores increases in diameter from its inner to its outer end. By this formation, a number of annular shoulders 8 are formed over which the jet of water must flow while passing through the passageway 3, thus effectually reducing the jet of water to a fine mist or spray before the same enters the boiler. It will be evident that the wear of the spray against the walls of the various bores is considerably less than would be the wear of an uninterrupted jet of water passing directly through a smooth bore. The water is therefore allowed to pass more quickly through the injector and into the boiler and is also in such condition as to be quickly and easily heated upon entrance to said boiler, these two features being extremely important and greatly prolonging the life and eiiiciency of the injectors to which the invention is applied.
As shown in the drawings, a circulating tube T may be employed in connection with my improved delivery tube, the inner end of said tube being threaded in an opening 0 which is formed longitudinally through the portion 1 of the tube 2, while its outer end lies flush with the outer end of said tube. The provision of this circulating tube, allows any steam or air which may have collected in the casing of the injector to be readily expelled therefrom, thereby preventing the movement of the water from being retarded. For more detailed explanation of the functions of the tube T reference may be made to my United States Patent 1,000,5i8, patented Aug. 15, 191.1, in which the circulating passages 15 perform identically the same functions as the tube T in the present case.
It will be clearly understood that, although the circulating tube T increases the efficiency of the injector, the delivery tube herein described might well be employed without this feature.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. An injector having a water inlet, a water outlet, a threaded bore between the two, and an integral delivery tube having an externally threaded portion engaged with the threads in said bore, the longitudinal passage in said tube increasing in diameter from its receiving end to its delivery end,
said passage abruptly increasing ,.in diameter at a plurality of points spaced substantially equi-distantly.
2. An injector having a water inlet, a water outlet, a threaded bore between said inlet and outlet, and an integral delivery tube having its intermediate portion formed W with an integral externally threaded enlargement, the threads of said enlargement being interengaged with the threads in said bore, thelongitudinal passage through said tube increasing in diameter from its receivqoples ot-thls patent may be obtained for fivecents' each, by addressing-the Commissioner of Patent;
ingend to its discharge end, saidpassage abruptly increasing in diameter at a plural-' ity of longitudinally and substantially equidistantly spaced points.
In testimony whereof I have hereunto set my hand in presence of two subscribingwltnesses.
