To all whom it may c0ncern.-

Be it known that we, HUGH L. VVARNER and WILLIAM H. LONSDALE, citizens of the United States, residingat Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Hydrocarbon-Burners; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relatesto new and useful improvements in hydrocarbon-burners, and possesses the advantages hereinafter described and claimed.

An object of the invention is to provide a burner of the above'type with an extra-high heating capacity and which is especially adapted to use in connection with boilers for generating steam for steam-carriages or auto mobiles and small steam-generators.

A further object of the invention is to provide a burner having the essential quality of durability and which is not liable to melt or become warped, is readily cleaned, a burner that will not light back or burn back, and thereby endanger the mixer-pipe or the detachable base.

In carrying out our invention it becomes an object to provide means for starting or vaporizing the fuel separately and independently of the main burner, which is therefore necessary before the main burner can be used.

In carrying out the objects of our invention, which, broadly speaking, is to provide a burner that has a high degree of efficiency and one which has special advantages that adapt it for use in connection with boilers for generatingsteam, we have paid particular attention to the details of construction, which are important factors in the attainment of the ends desired. For example, we have paid attention to the means for generating the hydrocarbon gas before it is admitted to the main burner, and thereby avoid the discharge of the hydrocarbon to the burner in liquid form. The generation of the gas occurs instantaneously with the admission of the oil to to the flame open.

the initial burner. We have also paid attention to the construction of the jet-openings in the main burner, with a view to overcoming" the objections hereinbefore noted. We have, further, taken into consideration the importance of not permitting air to enter between the upper edge of the burner and the lower end of the boiler.

It is well known to those familiar with burners of the above type that more or less difficulty is experienced in keeping the small jet-openings through which the gas escapes These small openings as commonly constructed have a great tendency to become stopped up with rust and a gummy substance composed of a mixture of vapor and dust accumulating on the interior walls surrounding said openings. This difficulty is greatly augmented by the great amount of dust created below the vehicle, and the result is the efficiency of the burners now in use for steam-generation for motor-vehicles is greatly reduced.

Preceding a detailed description of our invention, reference is first made to the accompanying drawings, which fully illustrate the same. I

Figure l is a top plan view of our improved hydrocarbonburner intact. Fig. 2 is a front elevation of the same. Fig. 3 is a side elevation, the rear portion broken away; Fig. 4, a side sectional elevation taken centrally through the burner. Fig. 5 is an enlarged section on the line as a: of Fig. 6; Fig. 6, an enlarged plan view of a portion of the burner surrounding one of the jet-openings; Fig. 7, an enlarged sectional View on the line m'w' of Fig. 6; Fig. 8, a top plan view of the generator. Fig. 9 is a front. elevation of the same, thedoor being removed; Fig. 10, a detached view of the generator-burner; Fig. 11, a detail of the fuel-distributing pipe. Fig. 12 is a top plan view of the burner, in which is shown some modifications in the construction thereof. A portion of the top plate is broken Fig. 14 is a section on the once indicate corresponding parts in the drawlngs.

The main burner is preferably circular in form and consists of top and bottom plates A and B, which are united by a surrounding wall 0. Projecting from the bottom plate is a series of tubes 13, which are joined to the top plate by ears, as shown clearly in Figs. 6 and 7. There is an annular space 6 on each side of the ears a, into which washers a fit. The upper ends of the tubes B are reduced in diameter, as at b, to provide suitable supports for the washers at. These washers have their under sides tapered in the direction of the annular jet-openings e, which openings are provided by said washers. The washers are removable when it is desired to clean the burner. The advantage of the under tapered surfaces of said washers lies in the fact that the ascending currents of gas are directed immediately to the gas-openings 6 around said washers. While We have shown the annular gas-openings e surrounding the outer circumference of said washers, it is readily seen that these openings may be arranged on the inner sides of said washers or the Washers themselves may be made to contain the jet-openings. It will be understood that the gas circulates throughout the interrior of the burner on all sides of the tubes B. The bores or openings B of said tubes enable a proper circulation of air above the jetopenings in the burner.

O designates a mixer-tube which is projected into the burner to the distance substantially as shown in Fig. 4. The lower side of this tube is cut away, as at G, to allow the propel-discharge to the interior of the burner at a central point in said burner. The inner end of said tube is closed by a wall E, which deflects the incoming gas out of the cut-away portion of said tube.

D designates a supporting-rim, which may be an integral part of the burner, orit may be detachable, as in the present case. This rim is mounted on top of the burner and aflords asupport for the boiler. (Not shown.) The lower edge of said rim is provided with an annular head or flange F, which has an annular groove F therein to receiveasbestos packing consisting of a cord G, whereby an air-tight joint orconnection is made between the burner and the rim. The upper edge of said rim is also provided with a flange F, having a groove D to receive asbestos cord G, by means of which an air-tight connection is made between the boiler and the rim D, the bottom of the boiler resting on the asbestos cord. The burner and the rim are connected by suitable bolts I, secured to the rim with their lower ends projected through lugs I on the side of the burner and receiving tightening-nuts I. The boiler may be socured to the rim in any desired manner-such, for example, as by the flanges K, which project from the said rim. It has not been thought necessary to illustrate the boiler in the drawings, as it forms no part of the present invention, and the mounting of the same on the burner is easily understood.

Referring to Fig. 12, this shows a maximum size of burnerfor example, a burner of twenty inches diameter. This size of burner is constructed on the same principles as the smaller sizes, as shown in Figs. 1, 2, and 3. In order to supply thelarger-size burner with the necessary quantities of gas, two mixertubes 0 O are placed therein. These mixertubes are fed from the nozzle O by means of a. T-fitting R, which is connected to said nozzle 0 and discharges into the two mixertubes through nipples S. p

In order to enable boilers to be cleaned without having to remove or detach the burner, we provide an opening T in the center of the burner, which is normally closed by a plug, as shown in Figs. 12 and 14. The upper portion 9 of said plug hasa tapering surface, which fits against a similar surface surrounding said opening in the top plate. The lower portion 71. of said plug has screw threads which engage with the threads in the opening in the bottom plate B. The two plugs g and h are connected by bars 1.. A plug usually closes an opening in the bottom of the boiler. This is a well-known feature of boilers of the type for which these burners are intended. Therefore an illustration of the same has not been deemed necessary. It may be stated, however, that said boiler-plug is in the center of the bottom of the boiler,

immediately above the opening T in the I burner, which opening, as before stated, is normally closed by the plugs g and it. Whenever it is desirable to remove the boiler-plug for any purpose, the. plugs g and h may be easily removed by means of a wrench and access then had to the boiler-plug. This is a feature of very great convenience, as it saves the time and labor incidental to the removal of the burner in order to get at the boilerplug.

Referring to Fig. 13, the bottom plate B is provided with an annular oil channel it on its top side. This channel, as will be seen, gradually inclines and deepens as it approaches the front of the burner, where it will be seen to have a greater depth. It therefore follows that any oil entering the burner through the mixer tube or tubes C will gravitate to that portion of the burner and will discharge through a pipe M, which communicates with the front of the channel to. The said tube it therefore will serve to drain the burner of all oil entering it. This is an important feature, owing to the fact that in the use of burners for motor-vehicles, boats, &c., there is more or less danger of the initial or generator burner going out or becoming extinguished in unobserved moments. The consequence of this is that the main burner is soon flooded with oil, and thus becomes a source of danger, as an explosion will naturally follow when the generation of gas takes place. By providing the drainchannel u and pipe u it will be seen that the oil will be at once conducted from the burner. The drip-pipe u. is very close to the receiving end of the mixer tube 0. This is desirable from the fact that when gas is entering the burner through the mixer-tube any portion thereof which may find its way into the pipe to will be quickly drawn into the receiving end of the mixer-tube and thence back into the burner under the suction created by the gas entering the mixer tube. Therefore there will be no perceptible loss of gas through said pipe u when the burner is in operation.

J designates a thimble secured to the rim D through ears J in a position above the mixer-tube O. This tube J telescopes with a similar tube N, which projects from the generator or pilot-house L. Within the tube N there is a generating-coil H, which is the terminal of an oil-supply pipe H. The coil H may be projected as far across the face of the burner as may be desired. This feed-pipe H lies above the upper surface of the burner and connects with a tank or other source of supply. (Not shown.) The coil H may be formed as shown in Fig. 8, or the coils may extend lengthwise or parallel with the tube N. The tube N is rigidly secured to the back of the pilot-house L and provides a connection and support therefor with the burner. With in this exterior compartment, which we have termed a pilot-house, a generation of gas for the main burner takes place through the means presently described and which means are amply illustrated on Sheet 3 of the accompanying drawings. The coils H,it will be seen, occupy the space of the tube N, and the inner end H of said coil projects into or connects with a neck 0, which is a part of a fueldistributing pipe of peculiar shape, as shown in Fig. 11. The downwardly-extended portion 0 of said pipe terminates in another right-angled portion O,which passes through a side wall of the pilot-house and provides for a valve-fitting M, through which a valvestem M passes, the valve controlling the admission of fuel to the initial burner. (Shown in Fig. 10.) It will be understood that a valve is located within the depending tube 0 at the junction of the extension 0. P is a dripcup, into which oil is discharged through said valve for the initial burner to flame. Before referring further to the initial burner, Fig. 10, we will complete the description of the fuel-distributing pipe, Fig. 11.

O is a tubular extension projecting at a right angle from the upper end of O and communicatingtherewith. Thisextension O joins a further extension 0 which extends obliquely and terminates in a discharge-nozzle that projects through the rear wall of the pilot-house and feeds the mixertube O,

as shown in Fig. 3. The upper end of the oblique extension 0 provides for a valve-fitting M, through which a valve-stem M passes to a valve which controls the discharge of gas to the mixer-tube C.

The initial burner, as shown in Fig, 10, consists of two right-angled portions Q and Q, the former of which projects into the coils H and forms the main heating medium for said coils. Referring to Fig. 10 of the drawings, it will there be seen that the extension Q 00- cupies an upright or vertical position and the horizontal or burner portion proper extends at a right angle from said upright portion. It may be said, however, that the upright or vertical portion Q" may be dispensed with by terminating it at a point adjacent to the horizontal portion Q, the latter portion constituting the burner and supplying the necessary initial heat. The rear end of said initial burner is closed by a wall Q which is provided with jet-openings f, as are also the sides of said burner. The upright portion Q terminates in a nozzle Q, which projects in proximity to the valve end of the pipe 0', from which it receives fuel. The nozzle Q" is connected to pipe 0 by means of lugs c and (Z. The pilot-house L is provided with a door L, hinged at L. In the upper portion of said door there is an opening L, which is closed by a panel of glass or other transparent material. This sight-opening is in line with the upper portion of the initial burner Q Q. Therefore the flame is always visible, and the accidental going out thereof may be quickly detected. Owing to the diiferences in the construction of motor-vehicles, it is impossible to have a fixed relative position of the pilot-house with the burner. We therefore have provided means for varying the position of the pilot-house when such becomes necessary. These means consist of the telescopic connections J and N, hereinbefore referred to, which form an adjustable connection between the burner and the pilot-house.

It is obvious that the pilot attachment shown on Sheet 3 of the drawings may be applied to other burners for use in connection with steam-boilers, and while we consider that our burner has many desirable advantages we do not wish to be restricted to the use of our pilot attachment therewith. On the contrary, we desire to claim said pilothouse broadly in combination with hydrocarhon-burners.

The operation of the burner is briefly described as follows: Thedrip-cupPis provided with oil through the valve M for the initial burner or generator, Fig. 10. This initial burner causes the vaporization of the oil and forms a gas, which is admitted. through the distributing-pipe, Fig. 11, by means of valve M the said gas being discharged to the mixer C.
