T OFFTQEQ JOHN F. BARKER, OF SPRINGFIELD, MASSACHUSETTS, ASSIGNOR TO GILBERT & BARKER MANUFACTURING COMPANY, OF SPRINGFIELD, MASSACHUSETTS, A CORPORATION.

HYDROOARBON-BURNER.

To all whom it may concern:

Be it known that I, JoHNF. BARKER, a citizen of the United States of America, residing at Springfield, in the county of Hampden andState of Massachusetts have invented new and useful Improvements in I-Iydrocarbon-Burners, of which. the following is a specification.

My present invention relates to improvements in hydrocarbon burners and of the type known as the multi-jet fuel oil burners.

One of the objects of invention is to provide a structure in which the oil nozzles are so arranged with relation to the air jets that complete oxygenization and thorough mixing of the particles of oil will be effected, and,

without any danger of extinguishment of the flames by the air pressure A further 0 bject of the invention is to provide a structure in which the oil nozzles, and consequently the flames, are symmetrically arranged at the end of the burner. With these and other objects in view, further advantages will be referred to in the body of the specification and particularly pointed out in the claims.

'It is a well known fact in the use of jet oil fuel burners, that the finer the particles of oil are subdivided by the aspirating or carbureting action of the air under pressure, the more perfect will be the combustion, and, at the same time a smaller quantity of the liquid fuel will be required to produce a given'tem- These two considerations are most im ortant in the useof jet fuel oil burners, as have found by repeated trials and ex eriments.

1n tempering, saya piece of polished. metal, if free oxygen is present the metal will be tarnished or darkened producing what is known as scale or burning the metal which is undergoing the process of tempering or annealing. My resent invention, is designed to overcome t ese serious defects, and, as stated above I have found by trial and experiment to effectually accomplish these results by my improvements which will be fully set forth in the body of the specification.

Referring to the drawings which form a art of this ap lication, Figure 1 is a longituinal sectionaFview of the complete burner showin the relative location and arrangernent o the parts. Fig. 2 is a detailed perspective View of the atomizing nozzles and Specification of Letters Patent. Application filed August 30, 1007. Serial No. 390,708.

of the burner which is provided with an internal plate or diaphram b, that divides the same into two chambers r and d. The chamber 0 being the receiving chamber for the oil through a suitable inlet opening e, and the chamber (i the air receiving chamber through a suitable opening f. (onnected to the main body portion a, by means of the threads is a barrel element h, in the outer end of which are, arranged the atomizing nozzles, and the spider 2' having the series of radially extending arms to which are secured by means of a threaded connection, as indicated at ls. the atomizing nozzles m. These nozzles being preferably provided with a cone shaped surface n to insure a proper hearing or shoulder for the threaded portion 7r.

Extending from the dia hragm I; to the spider i is a pipe 0 of suitab ie dimensions for conveying the oil to the spider and nozzles. The inlet end of'the pipe 0 being controlled by means of the needle valve 1), that is operated by means of the usual hand wheel qt Inthe outer end of the barrel 71 is secured a plate 7" by means of screws 8 that pass through the wall of the barrel and into the edge of plate 1", the receiving threads in the plate 7" being designated by the letter t. This plate is provided with a series of conicaltube 0 to the several nozzles m by means of the radial passage-ways w, in the arms of the spider, and at the same time the com pressed air enters the interior of the main passes from thence through the barrel h.

plete oxygenization and atomization of the body portion a through the openings f and around the arms j of the spider 11, through the openings u in the late 1 and issuing from these openings in c ose contact with the escaping oil from the nozzles m, whereby comment of air outlets will prevent the flame from being extinguished, It will be observed that the conical openings u in the plate 1" has the effect of directing the escaping air adjacent to the outer end of the nozzles as the air flows through the openings in the plate 1".

By arranging the end of the nozzles m flush with the outer face of the plate a there is no possibility of any back pressure of the air acting on the end of the nozzles m and preventing the free escape of the liquid fuel, as is-the case sometimes where the nozzles are arranged back from the outer edge of end plate.

By employing a multiplicity of oil jets the escaping oil ,is thereby sub divided into several streams, with theresult that by having the compressed air pass circumferentially around each nozzle through the conical openings it each jet is therefore subjected to an atomizing effect, whereas if only one jet for oil were used for the same quantity of oil the atomizing effect on the oil would not be nearly as complete, but on the other hand would be carried as small globules into the furnace causing a waste of the oil and incomplete combustion of the same. A further result in the use of multiple oil jets lies in the fact that should one or more of the jets be extinguished the remaining ones would immediately ignite the same, thus preventing the complete extinguishm ent of the burner as is the frequent occurrence when only a single oil jet is employed.

The construction herein described permits the use of interchangeable plates 1" for various air pressures which isa great advantage in this type of burner. This burner is primarily designed for a low air pressure, but is adapted for any of the air pressures now in common use, and any of the systems already installed.

What I claim, is I 1. In a hydro-carbon burner having in combination, a main body portion, a diaphram dividing the sameinto two chambers, a barrel portion connected With the main body portion, a spider provided with passageways and communicating with one of said chambers, nozzles communicating with the passage-ways of the spider, and a plate provided with conical shaped openings carried by the barrel and into which the nozzles project, whereby upon the passage of the hydrocarbon liquid through the nozzles andatmospheric air under pressure through the con ical-sha ed openings in the plate,'the liq uid fuel wil be atomized, as described.

2. In a device of theclass described, in combination with the main body portion, a diaphragm therein dividing the same into two compartments, one of the compartments being the oil receiving compartment and the other the air receiving compartment, a barrel element connected to the main body portion and carrying a series of nozzles at its outer end, and communicating means between the nozzles and oil compartment; a removable plate located in the end of the barrel provided with openings for receiving the nozzles means for regulating the flow of oil through the communicating means, and means for.

of conically shaped openings therein, nozzles.

entering said openings, and communicating means extending from one compartment of the main body portion to the nozzles, means for controlling the passageway through said communicating means, said nozzles being arranged flush with the outer end of the removable plate, as described,
