VAPOR-summa Specification of Letters Patent.
Application filed March 27. 1906. Serial No. 308.365.
Patented Dec. 3, 1907.
To all' whom it may concern:
Be it known that I, MICHAEL II. FARLEY, a citizen of the United States of America, and a resident of the city of Seattle, in the county' of King and State of Washington, have invented certain new and useful Improvements in Vapor-Burners, of which .the following is a specification.
My inventlon relates to certain new and useful improvements in vapor burners, and has for its primary object the production of an improved construction which will insure of the thorough vaporization of the gasolene or other volatile fuel.
With the above and other objects in view, to be referred to in the accompanying drawing, the invention consists of the construction, arrangement and combinations of parts hereafter described and succinctly defined in the appended claims.
Referring to the accompanying drawing, in which lie numerals ofreference indicate like parts throughout the several views: Figure 1 is a view in side elevation of an apparatus provided with my improved burner, the hood of which is shown in longitudinal section. Fig. 2 is an enlarged longitudinal sectional view of the burner. Fig. 3 is a section takenon line 3-3 of Fig. 1, and Fig. 4 is a detail view in front elevation of a nozzle for the burner hood, having a slightly modified form of mouth.
The burner consists of a vaporizing coil 1, one terminal of which is bent toform a pipe 2 through which the fuel is fed to the coil, the other terminal 3 being bent up to a point above the coil, then back in a line substantially parallel with the axis of the coil.
On the rear end of the terminal portion 3 is secured an elbow 4, and a burner nozzle 5 of Aany desired construction is connected with said elbow by a short section of pipe 6 which is preferably of such length to insure of the discharge orifice or mouth of the burner lying in axial alinement with the coil, and this burner nozzle is preferably spaced from tle adjacent end portion of the coil whereby the proper admixtureuof air with the gas, before it reaches the coil, is attained.
Now to insure of the fuel being vaporized, thereby obtaining a iiame which is free from sputtering, which is so desirable, especially in the art of brazing, to maintain the surface to be united, clean and free from unevaporated fuel, I arrange a core, as-7, within the coil 1 and rearwardly extending pi e 3 thereof, and this aside from causing t e fuel to iiow through the coil in hollow formation, becomes heated to a very high degree of temperature and aids materially in the vaporizing process.
Reference numeral 8 indicates a hood in which the burner is received, the same being formed with an internal, longitudinal oove 9, formed by suitably bending outwarglTy the metal of the hood, and in this groove the pipe 3 is iitted, the same having a snug fit therein, whereby the hood is held in proper position and prevented from twisting or turning.
The hood 8 is provided at its forward end with a removable nozzle 10, the same being crimped and slitted, as at 10, at its rear edge portion thereby forming resilient clips 11 which engage over a bead 12 on the hood. When desired nozzle 10 which has a circular mouth 10 can be removed, and another nozzle, as 13, havin an elongated mouth 13', substituted therefor, as is obvious.
I have shown my improved burner on a suitable apparatus, consisting of a tank or reservoir 14, for the fuel, which is provided with a pump 15, adapted to pump air thereinto to force the fuel out under ressure through a delivery pipe 16 with whic pipe 2 is coupled.
It will be observed that the coil 1 and end terminal portions 2 and 3 are formed from a single length of suitable tubing and in order to insure the proper positioning. of the core therein, I arrange the core, which as now considered consists of a rod of metal, in the tube before it is bent, and consequently in the formation of the burner, both the tube and core' are simultaneously bent.
Having thus described my invention, what I claim as new, and desire to secure by Let- .ters Patent of the United States of America, 1s
In a burner, a vaporizing coil, the forward terminal of said coil extending rearwardly above said coil, a hood inclosing said coil, said hood being crimped longitudinally thereby providing a groove snugly receiving the rearwardly extending portion of said coil,
