APPARATUS FOR BURNING HYDROCARBONS.

SPECIFICATION forming part of Letters Patent No. 463,853, dated November 24, 1891.

Application filed August 2, 1889.

To aZZ whom it may concern:

Be it known that I, JAMES H. BULLARD, a citizen of the United States, residing at Springfield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Apparatus for Burning Hydrocarbon, of which the following is a specification.

This invention has for its obj ect to provide a new and improved apparatus for burning liquid hydrocarbon in conjunction with air under pressure, whereby a gang of burners are susceptible of being employed to heat a series of furnaces to different degrees of temperature as occasion may demand and the burners with their oil-supplying pipes will be effectually drained when the act-ion of the apparatus ceases, for the purpose of rendering the system safe, reliable, effective, and economical, While fulfilling the conditions of safety required by insurance companies on property where oil-burning systemsareused.

To accomplish this object my invention involves the features of construction and the novel combination or arrangement of devices hereinafter described and claimed, reference being made to the accompanying drawings, in which the figure is a sectional elevation of an apparatus constructed in accordance with my invention.

In order to enable those skilled in the art to make and use my invention I will now describe the same in detail, referring to the drawings, Wherein The letters A indicate a gang of hydrocarhon-injector burners adapted to heat a corresponding number of furnaces B, so that each furnace is supplied with its individual hydrocarbon-burner, (one or more.) The burners are each composed of an upper vertical airinlet limb A, a lower vertical oil-inlet limb A and a lateral burner-nozzle A intermediate the two vertical limbs, in such manner that oil and air are admixed in the burner-body and discharged through the burner-nozzle for directing a fiame into a furnace. The upper vertical air-inlet limb A is provided with a cook or valve n for controlling the flow of air into the burner-body and the lower vertical oil-inlet limb A is provided with a cook or Serial No. 319,584:- (No model.)

valve on for controlling the flow of oil into the burner-body. The oil storage or service tank 0 is located at a point considerably below thegang of hydrocarbon-injector burners, and ordinarily it is placed under ground. The oil is supplied to this tank to such level as to create an air-chamber b in the top portion of the tank. A vertical oil-delivery pipe d extends from the storage or service tank from a point in proximity to the bottom thereof, andthis pipe connects at its upper end with a horizontal oil-distributing pipe 61-, which is furnished with a gang of vertical oil-conducting and burn er-draining pipes (1 which connect, respectively, with the lower vertical limbs A of the burners in such manner that when oil is forced to ascend the vertical oildelivery pipe d, it is delivered into the horizontal oil-distributing pipe (1 and distributed to the gang of oil-conducting and burnerdraining pipes d for supplying the gang of hydrocarbomburners with the requisite quantity of oil.

A horizontal air-distributing pipe f, located above the burners, is provided with a series of branches which connect,respectively, with the upper vertical air-inlet limbs A of the burners for supplying the requisite quantity of air thereto. A vertical air-delivery pipe f leads from the horizontal air-distributing pipe f and opens at its lower extremity into the air-chamber l) of the oil storage or service tank 0, and an air-pipe f extends from the air-chamber of an air compressor or pump D, of suitable construction, to compress air and force it through the system of pipes into the burners and into the air-chamber of the oil storage or service tank. By this means the oil contained in the tank is forced to ascend the delivery-pipe 61 into the horizontal oil-distributing pipe d, from whence it rises vertically through the oil-conducting and burner-draining pipes d to the burners A. At the same time the air conducted by the pipe f is delivered to the horizontal air-distributing pipe f and is distributed to the several burners, so that the admixed air and oil will issue from the burner-nozzles A for the purpose of heating the furnaces B.

The hydrocarbon-injector burners are each provided with its individual cock or valve for controlling the discharge of the air and oil therefrom, and the cooks or valves m n enable the flow of oil and air to the burners to be controlled at the will of the attendant.

The gang of burners constructed and arranged as described is important in that it enables the furnaces to be heated to different degrees of temperature, as occasion may de- IO mand. For example, the several furnaces can be heated by the one system to different degrees of temperature, according to the work to be performed, so that the respective workmen can control the heat of theirfnrnaces to 15 meet the conditions required.

The special arrangement described and shown provides a force-feed system for the oil, so that the objection to the gravity-feed system is entirely avoided, while the vertical arrangement of the oil-conducting and bu rner-draining pipes d and oil-delivery pipe (Z effectually an d thoroughly drains the burners and their supply-pipes for the purpose of avoiding leakage of oil from the burners when the apparatus is not in operation, and

also' to carry back all surplus oil to the storage or service tank and thereby entirely avoid the presence of any considerable quantity of oil in the pipe system when the apparatus is 0 inactive.

important in that they meet all the conditions for safety required by insurance companies.

The arrangement of the parts comprising 5 the plant is such as to materially simplifyits construction and operation and render the same economical, while providing for safety, reliability, and effectiveness.

By the action of the air compressororpump 40 the air in the air-chamber above the oil in the storage or service tank becomes compressed to the degree required for forcing the oilinto and through the oil-pipes to the burners, air in proportionate quantities being also sup- 5 plied through the air-supply pipes to the burners for the proper working of the apparatus. After the air-compressor ceases to operate there may be a reserve air-pressure sutlicient to force oil to the burners; but the cooks or valves m can be promptly closed for arresting the flow of oil, and the cocks or valves 71 may also be closed for arresting the, flow of air. The arrangement is such that any one of the burners in the gang can be cut out by simply closing the cocks at a belonging to such burner, thereby rendering this burner inoperative without effecting the action of the remaining burners in the gang. This is a desirable feature of the invention and ma 6c terially contributes to its merit and utility.

An oil-burning system has heretofore been proposed wherein a burner is connected by pipes with an oil-tank and with the air-chamber of an air-compressor, which also communicates with the oil-tank in such manner as These features of arrangement are to force the oil to the burner and at the same time supply the requisite quantity of air thereto. Such, therefore, I do not broadly claim as my invention.

Having thus described 2" y invention, what I claim is 1. The combination, with an oil-service tank and an aircompressor, of a gang of hydrocarbon-injector burners elevated above the oil'service tank, and each comprising an upper air-inlet limb, a lower vertical oil-lnlet limb, and a lateral burner-nozzle intermediate the two vertical limbs, a vertical oil-delivery pipe rising from the bottom portion of the service-tank, an oil-distributing pipe connected with the oil-delivery pipe and having a gang of vertical oil-conducting and burnerdraining pipes connected, respectively, with the lower vertical limbs of the burners, a hor1- zontal air-distributing pipe having a series of branches connected, respectively, with the up per vertical limbs of the burners, an air-pipe leading from the air-compressor to the airdistributing pipe, and a pipe connection between the top portion of the service-tank and the horizontal air-distributing pipe, the whole organized and arranged for conjoint action, substantially as described.

2.
