To all whom it may concern... r
'Be it known that I, TALBERT H: PHELPS, a "citizen ofthe- United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Asphalt Heaters, of which the following is a'specification.
My invention relates to asphalt; heaters,
primarily designedfor use in repairing or patching old asphalt pavements, the primary object'of the invention being to provide a heater of that type having a flame confining hood,'wherein provision is made for atomizing the fuel oil, by the action of an atomizing" and oxygenizing agent such as steam or air, by which the fuel will be injected into the hood'in such a condition as to insure instantaneous and cleanly combustion, the production of great heat and the elimination of smoke. v V
A further object ofthe invention is to provide a device of this character which may be supported upon a suitable truck for transportation-from, place to place or attached to a steam roller, as desired.
Theinvention' consists of the features of construction, combination and arrangement of parts herein fully described and claimed, reference being bad to the accompanying drawings in which 1 Figure 1 isaside elevation of an asphalt heater embodying my ll'lVeIltlOIlr Fig 2 is atop plan view of the same. Fig, 3 is a vertical longitudinal section through the heater.- tion.
In carrying my invention into practice, I
providea suitable frame structure, shown in the present instance as comprising parallel bracket arms 1 to which is attached a vertical, transversely disposed yoke 2, re-
inforced from the arms by braces 3. The bracket arms 1 are adapted for attachment to a suitable portion of a steam roller, for mounting the heater thereon, or for attaching the device to a suitable truck, allowing the device to be easily transported from place to place. Disposedbetween'the outer ends of the arms,,to which the yoke and braces; are connected, is a hood or drum 1, made ofsheet metal or other suitable ma terial and including a top wall 5, end walls 6 and aback wall 7 the front of thehood and the bottom and front of the drum being Fig. 4 is a vertical transverse secopen for the outlet of the flames and to en able the'flames toplay against the surface of the pavement to be repaired or attached.
Mounted upon the top or cross portionof the yoke or some other suitable support is an oil tank or reservoir 8 having a suitably cl'osed filling opening 9 and a suitably closed opening 10, to which may be attached a connection from an air pump for supplying air under pressure to feed the oil to the burners with the desired pressure. An oil feed pipe 11 leads rearwardly from the bottom of the tank and is connected in rear of the hood by a transverse pipe 12 to a pair of dependingdischarge pipes 13, which connect with burners or discharge nozzles 14, and extend into the hood through openings 15 in the rear wall thereof. The supply of oil to each I burner is controlled by a valve16, and it will be understood that'in practice any number of burners or nozales and controlling valves therefor may be employed according to the central union 18 for connection with a suitable source of steam or air supply. The ter minal ends ofthis pipe 17 communicate with the burners or injectors 14 for the supply of steam or air thereto, and the flow of steam or air to the burner or injectors being controlled by valves 19 in the steam or air supply pipe between the union and the burners or in ectors.
In operation, it will be understood that the hood is disposed over a portion of asphalt to be heated, and the valve 16 opened for the supply of fuel, after which the valves 19 are opened for the supply of steam or compressed air. The steam or air blowing, through the burners or injectors meets the currents of oil on their flow and atomizes the same, the atomized oil being injected into the hood, so that upon igniting the same an intense flame will be produced, which flame will be confined by the hood to the underlying surface of asphalt to be treated. It has been found in practice that the oil thus atomized when ignited burns cleanly and without the smoke, owing to the factthat the fuel is oxygenated, by which the carbon is raised to the point ofincandesc'ence and consumed. By this means the may be attached to a steam roller or other vehicle for use.
It will. be understood that any kind of hydrocarbon or other liquid fuel capable of atomizationand of being oxygenated in the manner described may be employed, and that the essence of the invention resides in a means by which an atomization of the oil and its combination with steam or air to effect combustion is secured. so as to obtain an intense heat with a consumption of car bon and the consequent elimination of smoke. V
It will be observed that by mounting the fuel reservoir above the hood and disposing the fuel supply pipe between the reservoir and hood, the apparatus is not onlymade compact in character, but a twofold additional advantage is gained, first in that the reservoir and fuel supply pipe are so located as to liein the path of upward travel of the air heated by the hood, whereby the fuel is kept in a desirable liquid state, thus a'voidingfany liability of the fuel thickening and becoming torpid in its flow during cold weather, and especially when a low grade hydrocarbon fuel is employed; and sec- ,ondly, by disposing the feed pipe between the reservoir and hood, the reservoir is heatedjust enough to keep the 'fuel liquid and withoutdanger of the formation of explosive gases, while the-pipe is heated to a higher degree to raise the temperature of the flowing fuel'to adapt it to combine to better advantage with the steam for oxy genation.
