To all/whom it may concern Be it known that I, HUGH'DALEY, a citiand aresident of Chicago, Cook count-y, `State of Illinois, have invented certain new and useful Improveniente` in Hydrocarbon-Burners; and I do hereby decla-re that the followingdescription of my said invention, taken in conne'ct-ion with the accompanying -sheet of drawings, forms a full, clear, and exact specification', which will enabl others skilled in the art to which it appertains to make and use the same. i

My invention relates to improvement-s in hydrocarbon burners, and it consists, essentially, in the novel and peculiar' comhina-tion of parts and details of construction, as hereinafter' iirst fully set forth and' -The object of my invention is the produc-f tion of a simple and eiiicient portable surface heater which may be easily propelled by hand. horse power, or, by attachment toa. suitable motor truck, for thel particular purpose of melting snow on rural delivery postal routes, on city streets and alleys, and on sidewalks. In the first named employment, ymy invention can be attached o either front or rear of a suitable motor vehicle, and pushed or pulled, as the case may be, over snow clogged roads. The lintense heat generated by my device, which, in acxtual use, will coveran actual area of about 30 square feet, will almost instantaneously melt all snow Wit-hin its area of operation, and the resultant water gutters at the side of the road. In the case of wide country roads, two or more of these devices may be employed to serve the entire width of the road. l

In practice, these devices are started out after a few inches of snow have fallen and follow the storm, returning over the saine route after reaching the end of their run.

Atourv hours by each device.

will ow into the Asthe outfits are'ar'ranged to travel at the rate of two miles an hour, it is evident that a large territory can be covered in twenty l In like manner my motor vehicle drawn heater may -be employed to dry muddy postal routes during the wet, springI season, the water on such roads being evaporated into steam and dissipated in the surrounding atmosphere.

Regular trips over such roads at stated in- Will convert the same from practi'- tervals,

cally impassable thoroughfares into goedA lanes of traiiic in a short space of time.

'Large municipalities spend .enormous sums of money every winter for snow removal from its thoroughfares., With the employment of a series of my outfits, ac,- companie'd by a suiiicient squad of swabbers behind to swab the melted snow into the nearest sewer manholes, streets may be l cleared at the rate-of two miles per hour andthe Water disposed of through the sewers at. a fraction of' the present expense.

Smallmaehines, hand' proplled, may also be used for clearing snow a ice from sidewalks, and, still another 'applicationis the softening of asphalt around breaks in streets for the `purpose of making repairs.

-In the drawings hereinbefore mentioned, I

illustrate my device as constructed for handl propulsion, but I Wish it understood that the same may be vehicle propelled without l the modification of any essential elements.

In Fig. l, I show a bottom plan of one of a series of hydro-carbon burners A, in which l is the hydro-carbon fluid. inlet, which inlet comprises a cross 2, or the like, 'the' side branches 3 and 3a of which communicate with Ts 4 and 4a by means of close nipples 5 and 5, The Ts li-andl"1L in turn, oonnect with elbows 6 and 6a through similarnipples 7 an'd 7a. The slde openings of said cross, Ts, and elbows point in the 'same direction; e., toward the rear of the heater, all of which construction is located transversely at the front end of the heater. From the Ts 4 and 4 and elbows 6 and 6n lead longitudinal. 9, 10', and 11, all .of which are closed at their free ends by 'suitable caps 8, 9", 10, and 11, relationship by a supporting bar 12', so'as to support said fiam'e tubes and maintain them in parallelism. The walls of said tubes, on their under sides thereof, are-pen forated by a multiplicity of, minute, closely horizontal Haine tubes 8,'

which caps are maintained in xed ilo - matter.

spaced holes 13, extending the entire length of the same. Directly under these perforations are located metallic strips or so called battle bars 15, for purposes hereinafter described.

Leading from the cross 2, above mentioned, between and parallel to flame tubes 9 and 10, is a similarly downwardly perforated flame tube 16. Thistube is surrounded by a jaeketing tube 16, made from brass or other metal of high heat conductivity, which tube is provided with perforations 17, registering with the perforations 17B, in the flame tube 16. This tube is capped at its free end, as are the others, by a cap 18a, which cap is similarly fastened to the supporting bar 12, already referred to.

Extending the entire length underneath the elbows G and G, the nipples 7 and 7, Ts fand 4a, nipples 5 and 5, and cross 2 is a metallic, more or which isadaptcd to contain a quantity of liquid hydro-carbon, which lwhen ignited will cause volatilization,by transmitted heat, of a mixture of hydro-carbon liquid a-nd oxy Gen introduced into the said parts through the inlet -member opening 1 of the cross 2, and passing through them into their respective flame tubes 8, 9, 10, and 11. If the mixture is not thoroughly volatilized when it enters these tubes, the liquid portion thereof will drip through the openings 13 onto the up-` per surfaces of the baffle bars 15, where said liquid will be ignited by the flame issuing from cup 18. The llames upon all of these bars .15 will, in a very-few seconds, heat the pipes 8, 9, 10, and 11 until complete volatilization is attained, after which llames of intense heat value will issue from all of the openings 13. AThese flames being projieeted downwardly are split apart, as it were, by the baille bars 15 and caused to spread on either side thereof, so that' the fl'ames from one of the llame tubes will impinge upon the flames from tubes` adjacent thereto on both sides, so that the area beneath the burner A is completely covered Y by a flame of intensepheat value.A The jacket 16a, surrounding flame tube 16, serves the same purpose as the ballie plates 15, but accomplishes the result much more rapidly. The unvolatilized liquid dropping through perforations 17 `and 17, ignite at the periphery of the jacket and the resultant flame completell surrounds the saine, thereby more quickly heat-ing the interior tube 1G in an obvious manner. rIhe object in more rapidly heating flame tube 1G is that the mixture enteringl through :inlet l, following the lines of least resistance, will more readily enter said tube, and must, therefore, be 4more quickly converted into volatilized 4A series vof tkwo or more of these burners "are mounted in parallel within and near.

the open bottom of a sheet metallic hood B, which is possessed of preferablyconverging sides 19 and 19a, vertical front and rear ends 21 and 21a, (the bottom edges of all of which are but a short dista-nce above the ground level to permit the egress of the gases of combustion) and a practically flat top 20. T he said rear and front ends are provide with a plurality of openings 22 and 22, adapted to be closed by sliding covers 23v and 23, so as to regulate the admission of the proper amount of oxygen to insure per- To the end Wall 21a, at a. point slightly below the inlets 1 of the burners A, are located brackets 24, supporting needle valves and bodies 25, the nozzles 26 of which are in' axial alinement with said inlets 1. From these needle valve bodies lead upwardly converging hydrocarbon tiuid'supply pipes 2.7 and 27, which terminate in a Y- haped casting 28, from which extends a main supply pipe 29, entering a fuel tank 29, located on the top of the hood B. A stop valve 30 is introduced in the fuel liney 29 for evident reasons. The hood B may be mounted upon wheels C and C, revolving upon axles and axle brackets 31 and 31, in which case a stiftening member 32 is fastened on the interior of the hood to render the sides 19 and 19 more rigid. In the fuel tank 29n is located an air pump 33 to createv suiiicient pressure, within said tank, to force the liquid fuel through the nozzle 2G ofthe needle valve and body 25 into the inlet 1 of the burner or burners A in a state of semi-atomizl'ation.

For the purpose of propelling the complete device byhand, by horse power, or by attachment to a suitable motor vehicle, as hereinbefore vdescribed, are provided handles, shafts, or attachments 34. Any form of attachment to a prop lling truck may be employed.
