VAPOR BURNER.
No. 469,443. Patented Peb. 23, 1892.
@XMIM/emo AIO UNITED STATES PATENT OEEICE.
JOHN E. DONOVAN, OF- CINCINNATI, OHIO.
VAPOR-BURNER.
SPECIFICATION forming part of Letters Patent No. 469,443, dated February 23, 1892.
Application led October 4, 1886.
l# To all whom t may concern:
Be it known that I, JOHN E. DONOVAN, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Vapor-Burners, of which the following is a specification.
This invention isanimproved vapor-burner.
Its object is to supply the burner with gas completely vaporized and mingled with the requisite quantity of atmospheric air to insure a perfectly blue smokeless iame of large volume and at the same time retain complete control of the volume of dame, whereby Iam enabled to reduce the volume to any extent required wit-hout extinguishing the flame.
lts object is also to remedy the trouble heretofore existing in some of this class of burners which causes the pulsation of the flame.
These objects I accomplish by the means hereinafter described, wheredy the gaseous vapor is supplied in a highly-heated state to the commingling-chamber unmixed with any of the liquid from which the gas is formed.
rlhe invention also consists in the peculiar combination and arrangement of the several parts to accomplish these results, all of which will be first fully described in connection with the accompanying drawings, and then particularly referred to and pointed' out in the claims.
Referring to the drawings, in which like parts are represented by similar referenceletters wherever they occur throughout the Various views, Figure l is a central vertical section of my improved burner and its attachments. Fig. 2 is a top plan view of the same. Fig. 3 is a detail sectional view, upon an enlarged scale, of the supply and discharge tubes shown at the right-hand side of Fig. l. Fig. 4 is an inverted perspective view of the dem tachable burner-cap.
The pipe leading from the reservoir is represented by A. It connects with the union B, the branch b of which is screw-tapped to receive the spindle C of the ordinary needlevalve. Into the vertical portion Z1 of the union is screwed the tube D, the lower end of the tube extending downwardly within the union to a point above the needlevalve, the

end of the tube and the screw-threaded plug upon the cross-head E forming a chamber b2, surrounding the intermediate tube F, which passes within the tube D and rests upon the end of the screw-plug c, which closes the end of the union Z9. Within the tube F is an inner tube G, which I term the vapor-supply tube, which is screw-tapped into the end of the screw-plug e. H is the vaporizing-chamber. It has boss h extending down from its under side, into which is screwed the top end of the tube D. 'Ihe intermediate tube F extends up into this boss, preferably a short distance above the end of tube D, while the inner tube G extends to the top of the circular chamber H and has slots or U-'shaped depressions around its top edge to permit the vapor to pass from the chamber II down through the tube G, through a perforation in the plug e, and thence through a perforation in the cross-head E to the discharge-orifice in the vertical portion E of the cross-head. The opening in the upper portion of this vertical part E is closed by a needle-valve on the upper end of the spindle I, which is screw-threaded through the vertical portion Eand controlled by a hand-Wheel I. The commingling-chamber is formed by the under side of the Vaporizingchamber II and the circular dish-shaped casting J, which has a tube J, cast with it, extending down in proximity to the vapor-discharge orifice e and up above the bottom of the casting J and within the detachable burner-cap K. The upper portion of the casting J is perforated with a row of jets j, and the cap K is similarly perforated with a circular row of jets 7e. This cap K passes over the extended end of the tube J and rests upon an annular ange h', projecting inwardly from the chamber Il. The piece J has a boss j extending down from it, which is perforated to pass over the tube D and is tapped to receive a set-screw J 2, which holds it firmly in place against the exterior annular ange h2, surrounding the chamber I-I. The bosses h3, of which there are four extending out from the chamber H, furnish openings through which the core-bearings pass in casting the chamber inasingle piece. The bosses are screw-tapped and stopped with screwplugs Trl. L is the ordinary oil-cu p, in which with a perfectly smokeless blue ilanue.
oil is ignited to initiate the vaporizing process. The lower end of the intermediate tube F, which is within the chamber b2, is perforated to permit the fluid from the supplytank to pass between the tubes F and G, as well as between the tubes D and F, on its way to the vaporizing-chamber H. The iluid passes from the reservoir (not shown) through pipe A, and thence up into the lower part of chamber H, a portion of the fluid passing between tubes D and F and a portion passing between the tubes F and G. The vaporzed iiuidwhich arises within the chamber H is forced by the pressure generated by the vaporizing process down through the tube G and delivered from the perforation e into the tube J', carrying along with vit the requisite aiiiunt ofatmospheric air, and thencevinto the enininingiingehamber JS, fon-ned by the parts H, J, anfd'K. The vapor' passes out through the perforatins 7' and la', and bei'ngignited burns The naines frein jets k, iinpinge upon the upper surfacejor top of the chamber H, heating it intensely. The lchamber isalso heated upon the under sidje bythe highlysheated vapor in the comininglingchaniber J3. The heated vaporpassing down lthrough the tube G partial-lyvheats'the Huid passing up around it to Ythe 4ebainber ji, and the `fluid between the tubes fandF and F and D, being in `conunihic'atio'n above and below tube D, equalizes rthe pressure and prevents the pulsations of the naine so annoying in thel burners new in eoininen use, because the uuid thus entering between lthe 'tubes is particularly heated and expanded before it reaches the bottom of the vaporizingchamber. The process ofvaporization is vtherefore gradual from the time the fluid enters the 'vertical branch o of Vunion B until the perfectly-vaporized tluid 'from the top of chamber H, is forced into the tube G and thence discharged in a constant steady stream from nipple e through tube J to the commingling-chamber, while the intermediate tube F, perforated below, prevents the formation of parafiine and insures amore perfect Vaporization of the fluid discharged through the jets j and It. This tube F is not indispensable in myr organization, as the de- `vice will accomplish good results without it.
The section of pipe A (shown in Fig. 2) is a continuation of the tube A to be used when more than one burner is to be employed in the same stove.
What lclaim aslnew, and desire to secure 1. In a vaporlburner, the combination, sub stantialiy as specified, of the vaperizingchamber H, the burner ksurrounded by said chamber, the uuid-supply tube D, leading to the bottom of said chamber, and the vapordischarge tube G within 'said tube D iii coinnnunication with the top of said chamber.
2A. The combination, 'substantially as' 'speci- Iied, of the vaporiZi'ngL-cha'mber, the supplytubes D and F, leading to the bottom 'of said chamber, and the vapor=discharge tube leading from the top of said chamber, the said tube F being intermediate the tube-serena D and perforated near the bottom, for lthe purpose set forth.
3. The combination, s'ubstant'iallyas specilied, of the chamber H, having flanges h h2, the dish `J having its upper edge bearing against flange h2, the tube J', and detachable cap K, said cap and part J being perforated as described, for the purpose setvforth.
