LIQUID+FU EL HEATER. 5

Application filed August 12,1924 Serial No. 731,648.

To all whom it may concern."

Be it knownthat 1, ROBERT L. Comma, a c1t1zen+of the United Statesy and resident; of

San Antonioyin: the county 'oflBexaivand Stateof :TeXa-s, have invented a newt-and .l of substantially U-shaped for1nat1on 1nclud Improved Liquid F uel Heater, of: which the following is a full, clean; and exact descriptions This invention has relation-to liquid fuel heating devices and has particular reference to an improvement in-fuol oil heaters which are especially designed for use in connection with steam, hot water or hot-air furnaces.

One of the principal objects of the present invention, is to-provi'de a-means for thor oughly' gasi-fying the fuel oil, pr-iorztothe ignition of thesame, wherebyithe maximum heat may be derived therefrom;

As a further object the invention; contemplatesin a fuel oil heater, a means for effectually mixing; :theair and gas to pro mote a more thorough combustion thereof, which means also servestoyeffectually;1radiate the heat anddistribute the same throughout the fire box in which the device is located" As a Stld-hfllltllOl. object the invention comprel'iends an improvelnent in fuel oil heaters which is comparativelysimple-in its construction, I inexpensive to manufacture and install and which is thoroughly reliableand highly efficient in itsplu pose.

\Vith theab'overecited and other objects.

in View the inivention. resides in-the novel construction set forth in the; following speci-. fication, particularly,pointed out in the aps pended claims and illustrated in :the accompanying drawings, itbeing understoodthat the right is reserved to-eiinbodiments other than those actuallyillustrated herein, to the full extent indicatedby the general meaning I of the terms in which tllG'Olitllllb' are expressed.

In the d rawings Figure l is a perspective view-o-fthe device;

Fig. 1 is a perspective view of the heating cup used for starting the'burner;

Fi g. 2 is a transverse sectional viewthrough the heating device taken approxi mately on the line 2-2rinllig l; and

Fig. 3 is a horizontal sectional view taken approximately onthe line 33 in Fig; 2.

Eeferringsto the drawings by characters of reference 10 designates a supportingbase for the device whichis provided at oneend withian upstanding standards 11 which sup ports atiits upper end the bight portion 12. of the fuel gasify'ingaor generatingelement designated generally at 13 which'element is is provided! with a depending pipe or conduit 21 connected thereto by an elbow 22oand said pipe 21is connected at its lower end by an elbow. 23 with the base 10' byvmeans of attaching ears 24 and bolts 25 which extend ithi'ough" the ears and base 10; From theelbow 23a pipe or conduit 26 leads horizontally, to the loweriend of .a nozzle 27 which [is disposed centrally below the gasifying or generating memberl3.

super-posed air and gas mixingi and heat radiating element designated generally by,th'e reference character 28' is supported from the gasifying or generatingelement 13 and the said element-28 consists of a rectangular shaped element 29 having a double archshaped. bottom 30' provided with a central depending stem 31 which is gripped by the parallel pipes 14 and 15 of the gasifying or generating element 18. The side walls of therectangular shaped element-29 are pro,- vided with a plurality of perforations 32 botlra'bove and below the depending arch shaped bottom 80'. An air supply pipe 33 having a perforated lowe1 ,end'34l leads cen trallyinto the element 29' and rests upon The bottom 30. The leads or pipes 14- and 15 are disposed immediately below the convex undersides definedby the d0uble-arch shaped bottom 30. y

In startingthe device, a heatingcup or pan is employed which is provided with a handle 36; Keroseneis pouredinto-the heatingcup or pan'35 and thesame is arranged under the generatingelement 13' af-v ter which the kerosene is-lighted and a sufficient amount of fueloil is permitted to enter the generating element. The heat from the heating cup or pan-35 will initially heat the generating, or gasifying'element 13 until the tit) gas starts to feed through the nozzle 27. The gas from the nozzle 27 will then be ignited and the valve 18 will be controlled by the manipulating handle 19 to permit the fuel oil to be fed to the generating element 13 to the supply pipe 16 where it will be continuously gasified or generated into a gas as it feeds through the pipes 14 and 15, and the pipes 21 and 26 to the nozzle 27. The jet or flame from the nozzle 27 will be deflected or spread laterally by a spreader element 37 adjustably supported from the depending stem 31. The flame will thus be directed upwardly and outwardly around the air and gas mixing and heat radiating element 28, a part of the heat being deflected inwardly and around the pipes 14: and 15 of the generating element, by the convex underides of the depending arch shaped bottom 30. At the same time the cold air descending through the pipe 33 will be deflected laterally through the perforations 34: and the perforations 32 to thoroughly mix with the gas and flame whereby to promote a thorough and complete combustion. It is of course understood that after the burner is started, the heating pan or cup 35 is removed. The perforated or foraminated walls of the rectangular element 29 serve to spread or radiate the heat to uniformly distribute the same through the fire box of the furnace and prevent the draft from drawing the same through the chimney before it has had sufiicient time to thoroughly function to heat the furnace fire boX.
