PATENT OFFICE. a J
JOHN F. HARMAN, OF KANSAS CITY, .KAVNSA'S, y,
' OIL-BURNER.
The 10 ham it may concern:
Be it known'that I, JOHN F. HARMAN, a
citizen of the United States, and resident of.
Kansas City, lVyandotte county, State of Kansas, have invented a certain new and useful Improvement in Oil-Burners, of which the following'is a complete specifica- The present invention relates to burners, and aims to provide an improved construction of burner of the oil type, and one of the principal objects in view is to devise a burner'construction in which the oil vapor is fed into a fuel receiving chamber which is located within the flame zone of the burner, together with provision for preventing overheating of said fuel receiving chamber and of the fuel vapor being fed thereinto.
To this end I have devised a burner construction having a fuel receiving chamber located within the flame zone of the burner and having a vapor generating tube leading through the flame zone and discharging its vapor into the fuel'cha-mber, and a casing or housing arranged to inclose a portion of said vapor generating tube as well as the fuel receiving chamber, said casing or housing providing an air chamber to which air passages lead from the bottom of the burner for conducting a continuous supply of air intothe air chamber for cooling purposes.
It is alsosought to devise a fuel supply connection having an improved arrange-. ment, in that the conduit for the supply of fuel is arranged to extend fora distance through the flame zone of the burner just prior'to its discharge of said fuel into the vapor generating member, for thus effecting an initial heating of the fuel preparatory to the vaporizing action of said generating member. v
With thes general objects in view, the invention will now be described by reference to the accompanying drawing illustrating one form of construction for embodying the proposed improvements, after which the novel features therein will be particularly set forth and claimed.
In the drawing Figure 1 is a side elevation of a burner construction embodying the proposed features of improvement, certain portions of the burner being broken away to disclose the various chambers 0r compartments of the burner;
Fig. 2 is a plan view of the same with the sides and front end of the chamber Specification of Letters Patent, Patented 11116 28, 1921 Application filed March 2, 1920. Serial N 2,812.
casing or housing forming the improved cooling chamber represented in section; and Figs. 3,4, and 5 are transverse sections taken on the lines 33, 44, and 5 5, respectively, ofFig. 1.
Referring now-to the said drawing in detail, this illustrates the improved burner structure as comprising a casing or casting ber 7 through a passage 12 froma central longitudinal channel or passage 14 in the base of the burner. From the chamber 7 the vapor passes by way of two lateral and downward extensions 15 at the rear of said chamber and at the rear end of the burner, into two vapor distributing chambers 16 extending longitudinally of the casting fiat the opposite sidesof the burner-. The said chamber 16 is provided with a plurality of slits or flame orifices 17 along both sides of the burner, and also with a series of similar orifices 18 in the top ofthe burner to the front of the chamber 7 and underlying the generator tube p The foregoing represents a burner construction of a type commonly in use, in the operation of which it is found that more or less difficulty is experienced from the-tendency of the chamber 7 to become overheated and causing the fuel to ignite within said chamber before passing into the distributing chamber. Accordingly I have devised a cooling means for overcoming such overheating tendency duelto the position of said receiving chamber within the flame zone of the burner as defined by the flame jets or orifices 17 at the opposite sides of the burner. For this purpose I provide a hous ing or casing 20 adapted to fit over that portionof the casting 6 which forms the chamber 7 and secured thereto by means of screws 21, the shape and size of said casing such as the ; as seen in Figs. 1 and 2, the front end of the casing 20 embraces a portion of the rear end of the g ne a r tube 8, for which the front to form an air chamber 22 surroundin wall of the casing is provided with an opening 23, and into this front end portion, v ,7 v of the chamber 22 air is admitted throughfFigs. 1 and 4.) B-ythe arrangement shown and described with reference to the oil of a passage 24 communicating with the longi:
tudinal passage l iat a point slightly" in front of the passage 12, the front wall of the'chamber7form1ng the vertical partition between the passages 12 'and' 24. Additional passages are provided for admitting air to the'side's of chamber 22, as'indicated at% in; Figs,':1; 2, and i," the passages beingformed Pbyrproviding partitions 26' between the side-walls of the longitudinal channell l parallel to thetube 8 into'proximity to the and the two distributing chambers 16, the said 'passa'ges-25being thus arranged to receive. air from the bottom face of the burner and conductthe samevup throughthe burner casting 6 intothe-bottom of the chamber 22.
Theffuel supply to the burner is conducted thereto' by means of apipe 28 leading V heating-.offuel-liquid prior to its entry into the tube'8, I extend this pipe28 through the flame zoneprovided at theFfront end of'the burner'iover'theorifices' 18, Figskl and 3 of the drawinglshowing said pipe extended frontvend'oftheicasing 20 and then back to the outer en'd offthe" tube 8 through the flame zone of the burner and on the opposite side ofsaid 'tube 8;
- It-will thus be seen-that "I have provided a" simple and efficient form and arrangement of; burner construction for carrying out the de'siredobjects of the'invention. By the means of my improved cooling 'structure the temperature'of the, fuel or vapor "receiving chamber? is keptbelow the danger point atwhichthevapor within'said chamber would ignite,:anfd;said fuel vapor still maintained at a sufficiently high temperature for eflicient combustion" on" being conducted through :the passages 15 and distributed thereby into the chambers. 16 to the flame orifices-17 and-18. Forallowing'the proper circulation of-the air through the chamber" with a plurality of vent openings 30.
(See
fuel'pipe for conducting the fuel to the generators, and extending this pipe through the flame zone of the burner, it'iseviden't that an initial-heating action isimpartedto the fuel prior to its entering the generator tube 8, with the result that said fuel is'sup plied in a pre-heated condition, inwhich statea much'inore effective vaporizing-action :by the generator tube "8 is made pos sible.
While I have shown and described what I; now regard asthe preferred 'form of construction, I desire to reserve the right to make such changes as may fairly fall within the-scope ofthe following claims. What I claim is: 7
1. An oil burner comprising a casing providing a fuel receivingchamber and having flame orificesarranged to provide a flame zone surrounding said chamber, a vapor generating tube-passing through said flame zone and feeding into said-chamber, and-a second casing interposed between'saidorifices andsaid chamber and surrounding a portion of the generating tube adjacent to said chamber for providing an air chamber" adapted topreventoverheating of the vapor being-fed into said fuel receiving fchambera 2. 7 An oil burner comprising a casing providing'a fuel receiving chamber-andhaving flame orifices arranged to'providea flame zone surroundlng'saidchamber,and a sec ond casing interposed between saidorifices and. said fuel receiving chamber and providing an air chambersurrounding said fuel receiving chamber, forfi preventing overlla'fi ing thereof, said first casing being provided with passagesfor conducting air fromthe lower face thereof into the bottom of saic air chamber.
Y r In witness whereof I hereto afiixmy signature.
