. SPECIFICATION forming part of Letters Patent No. 552,419, dated December 31, 1895.

Application filed May 24(1895. I Serial l l0. 550,552. (N0 model.)

To all whom it may concern.-

Be it known that I, CHARLES R. CLARK, of Chicago, in the county of Cook and State of Illinois, have invented a new and Improved Gas Generator and Burner, of which the following is a full, clear, and exact description.

The invention relates to an improvement in that class of gas generators and burners wherein a generating-coil or its equivalent is provided, and made capable of receiving a supply of oil which is subsequently formed into gas by the heat of a burner below; and the main object of the invention is to provide a device which will be especially capable of use in connection with stoves formerly adapted for burning wood and coal, and so stoves and made to take the place of the wood or coal fire which formerly heated the stove. This end I attain by certain peculiar features of construction and combination and arrangement of parts, as will be fully described hereinafter, and finally embodied in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 represents a longitudinal section of a burner and generator constructed in accordance with my invention, and showing the 2 is a plan view of the invention, the deflector-plate thereof having been removed to disclose parts beneath it. Fig. 3 is a vertical cross-section of the burner on the line 3 3 in Fig. 1, and showing-the relative arrangement of the fire-box; and Fig. 4 is a detail view, partly in section, and illustrating a tool for use in connection with my invention.

The reference-numeral 10 indicates a castiron box or casing, which is rectangular in form and which has its upper end open. The box or casing 10 also has its inner side cut away at 11, so that the flame and heat from the burner may more readily and efiectively reach the stove and heat the same, as may be seen by reference to Fig. 3. This box 10 is seated within the fire-box 12 of the stove, as shown in the drawings, and the sides of the box are packed with fire brick or clay so as The air which is essential to the operation of the burners is admitted into the box 10 through the openings 13 which are formed in the bottom of the box, the whole being so arranged that these openings will have communication with the atmosphere through the usual draft-openings of the fire-box. It will be understood that the box 10 is so located that the lids of the stove may be placed over it. These lids are not illustrated in the drawlngs.

Seated Within the box 10 is the base-plate ll of the device, and this base-plate is also rectangular in shape and has projecting downwardly from its edges the flange 15, which has formed therein a series of openings 16,through which the air is admitted from under the baseplate and into the space occupied by the burners. The base-plate 1 1 has also, at its edges, an upwardly-projecting flange 17.

Rigidly secured to or formed integral with the'respective ends of the base-plate 14 and rising vertically therefrom are the standards 18, which are two in number and which have rigidly secured to their upper ends, by means of a bolt 19, the lugs 20 of .the frame 21. The frame 21 consists of a bar cast integral and rectangular in form, it being of a size equalto that of the base-plate 14. This bar is angular or L-shaped in cross-section, as

may be seen by reference to Figs. land 3 of the drawings, and is provided to carry the generating-coils and mixing-cones, as will be fully described hereinafter. The frame 21 is formed with a bend 22 at its middle, and.

this bend 22 is placed upon half of the frame out of the plane occupied by the remaining half, the purpose of which is to permit the reception of the lower coi 23 of the generating-tube.

The generating-tube passes into the box 10 at its inner side and proceeds horizontally throughout the length thereof. It is next :curved, as shown at 24, and extended along union and longitudinally with the length of the base-plate 14:. The pipes or tubes 26 terminate over the projections 27 formed on the upper side of the plate 1-1, and are provided with gas-emitting nozzles 28. The nozzles 28 are one for each of the pipes 26 and have their discharge-openings disposed vertically, so that the gas will be directed upwardly therefrom and into the region of the generating-pipe, as will be understood from the drawings.

The frame 21 has formed on its upper side a series of transverse projections 29, upon which the generating-pipe lies, and these projections are provided to assist in the support of the said pipe. The edges of the frame are also provided with upwardly-projecting studs 30, which pass by the coils and serve to hold them against lateral movement. The frame 21 is further provided at each inner side of its ends with curved projections 45, which pass by the inner sides of the coils 2-1 and 23 and serve to further assist in holding the said coils in place.

Formed'integral with the under side of the frame 21 and projecting downwardly therefrom are lugs 31, which are extensions of the vertical part of the angle-bars composing the frame 21 and which are adapted to have the arms 32 bear against their under sides. The lugs 31 are four in number and are arranged in two pairs, the members of which are respectively opposite each other, while the arms 32 are one for each of the lugs and are formed respectively two integral with each of the mixing-eones 33. The mixing-cones 33 are formed of cast metal and substantially frusto-conical in form, though the sides are angular, as will be seen by reference to Fig. 2 of the drawings. By means of the arms and lugs 31 these mixin g-cones are held rigid on the frame and in the proper position, they being located one with its upper end on the same plane as the coil 23 and the other with its upper end in the same plane and directly below the bend 2% of the generating-tube. The purpose of these devices is to confine the gas escaping from the nozzles 28 and to mix therewith that amount of atmosphere which is well known to be essential to the combustion of the gas. The cones also serve to confine the flame and to direct it properly.

Rising vertically from each end of the frame 21 and extended at a point above the upper edge of the box 10 are the arms 34. These arms are two in number and have their upper ends in the same horizontal plane and formed with open bearings 35, which respectively receive the trunnions 86, formed integral with the deflector-plate 37. The deflector-plate 37 is formed of cast metal and is of a length and width equal to that of the frame 21. The under side of the deflector-plate comprises two downwardly-curved surfaces 38, which come to a juncture at 39 and form thereby a longitudinally-extending rib. The surfaces 38 are curved in the are of a circle and the ends of the plate are provided with arc-shaped projections or plates 40, which are one for each end and which project downwardly therefrom.

The purpose of the plate 37 is to deflect the flame from the cones 33 and to make it possible to direct the same against the oven side of the stove or burners, as may be desired. It will be seen that by swinging this plate on its bearings so that its upper face will be inclined, the flame, upon striking it, will be directed up the inclined under side and in the direction desired by the person using the burner. Formed in the upper side of the deflectorplate 37 are the recesses 41, which are provided for the reception of a manipulatingtube and whereby the plate may be adjusted on its bearings or removed and replaced;

hen it is desired to shut off the burner, this will, as is well known, be effected by stopping the flow of oil into the generator tube, but to effect an immediate extinction of the flame I provide the tool illustrated in Fig. 4, which consists of a shank 42 having at one end a cup-shaped device 43 and at the opposite end a drill or punch M. hen. now it is desired to immediately extinguish the flame after cutting oif the supply of oil, the deflector-plate 37 may be removed and the tool referred to introduced into one of the mixing-cones 33 and the cap 4-3 made to cmbrace the emitting portion of the nozzle 28, which is under the cone, so as to cut off the supply of air and extinguish the flame. The drill or punch l4; will be useful to clean the nozzles 28 should they become clogged with deposits from the oil or gas. The object of quickly extinguishing the flame, after the supply of oil has been cut off, is to permit the residue of the oil in the generating-tubes to pass off in the form of unconsumed gas and thus prevent the oil from passing out of the nozzles, which would have the eifect of clogging them up with hydrocarbon deposits.

The use and operation of my invention will be well understood, and therefore it will suffice for me to say that in the operation all that will be necessary, after the assemblage of parts, is to turn the oil into the generatingtubes or coils and to ignite that which passes out through the nozzles '28, so that the flame may rise into the Vicinity of the generatingcoils and heat the same sufficiently to form the gas. As the gas begins to form it escapes through the burners or nozzles 28 and becomes ignited and burns, all of which is the same as in prior devices and needs no further description.

It will be understood that the purpose of the lower coil 23 is toallow the gas generated in the tube to be superheated before reaching the burner-nozzles,which operation has a wellknown and advantageous effect on. the operation of the burner.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-- 1. In a gas generator and burner, a supported frame having upwardly extending pro jections at its ends, a generator coil and burners carried by the frame, and a deflector plate rockably mounted in the projections and havin g two outwardly and upwardly curved sides with flanges at their ends, substantially as described.

2. In a gas generator and burner, a box, the same having an open top and side, a base plate rested upon the bottom of said box and having at its edges downwardly-projecting flanges, the same having notches therein, standards rising from the ends of the base plate, a frame secured upon the standards and jections, a generating coil, the same having 20 a horizontal upper portion lying upon the higher part of the frame and a parallel lower part resting upon the lower part of the frame, burn er orifices, and mixing cones, substantially as described.
