HEATING APPARATUS.

Application filed June 1,

To all whom it may concern:

Be it known that I, Gnonor. E. CUsTER. a citizen of the United States. residing at Providence. in the county of Providence and State of Rhode Island, have invented new and useful Improvements in Heating Apparatus, of which the following is a specification.

This invention relates to an improved heating apparatus and has for its object to provide an apparatus for use in the tire boxes of stoves, furnaces and the like. the said apparatus being capable of generating a gas from any of the available fuel oils. combining said gas with air and conducting the resulting gaseous mixture to suitable burners where the mixture is utilized as a fuel for said burners.

Another object of the invention is to provide an apparatus so constructed and arranged that the jets of flame from the various burners will be d rected upon the interior walls of the heaters in which they are utilized in order that a maximum amount of heating value may be obtained from the apparatus.

Another object of the invention is to so construct the burners and generator that they may be adjusted relatively to each other to fit the various heights of lire boxes in which the apparatus may be located.

The invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.

Referring to the drawings:

Figure 1 represents a plan view of the heating apparatus embodying the invention.

Fig. 2 is a front elevation of the heating apparatus, a portion thereof being broken away to more clearly illustrate certain parts of the apparatus.

Fig. 3 is a central vertical section as taken on the line of Fig. 1.

Fig. 4 is a central vertical section taken at right angles to the line 33 of Fig. 1.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 5 represents an annular main burner consisting of two members 6 and 7 which are secured together at the front and rear by straps 8 and 9 respectively. The members 6 and '4' of the burner 5 are each provided with a chamber 10 upon the interior thereof and a portion of the outer Wall is inclined at 11, and said inclined wall 1923. Serial No. 642,782.

is provided with a plurality of openings 12 in which burner tips 13 are located; said burner tips being provided with a plurality of small openin s 14 formed therein through which the gas ows. the combustion taking place adjacent to the outer ends of said openings. The burner 5 is rovided With a plurality of legs 15, each ot said legs being provided with a slot 16 therein and being adjustably secured to said burner through the medium of a screw 17 which passes through the slot 16.

Superimposed upon the main burner 5 is an annular auxiliary burner 18 which consists of members 19 and 20 which are secured together at the front and rear by straps 21 and 22 respectively. Each of the members 19 and 20 are provided with a chamber 23 upon the interior thereof and the upper walls of said members are provided with a plurality of openings 24 formed therein in which are located burner tips 13 similar to those previously described. The auxiliary burner 18 is adjustably secured above the main burner 5 through the medium of a plurality of supports 25, each of said supports being provided with slots 26 and 27 at the upper and lower ends respectively, the lower ends of said supports being adjustably secured to the main burner 5 through the medium of screws 28 which ass through the slots 27 while the auxiliary burner 18 is adjustably secured at the 11 per ends of said supports through the me ium of screws 29 which pass through the slots 26 in said supports.

Mounted upon the auxiliary burner 18 is a generator burner 30 which is adjustably supported beneath the auxiliary burner through the medium of a pair of supports 31. The generator burner 30 is provided With a chamber 32 upon the interior thereof and in the upper wall of said burner are located a plurality of burner tips 13 also similar to those previously described. Located upon the opposite sides of the generator burner 30 are grooves 33 which extend longitudinally of said burner, and located in each of said grooves is a wick 34 preferably composed of asbestos or some other suitable material.

Mounted upon the auxiliary burner 18 and positioned directly above the generator burner 30 is a generator 35, and said generator has been separately illustrated, described and claimed in a pending application, Serial Lii No. 624,026, filed March 9, 1923. Briefly de scribed, however, the generator consist of a manifold 36 which is rigidly secured to the under surface of the auxiliary burner 18. The manifold 36 is provided with a chamber 37 formed therein and has a pair of generator tubes 38 mounted thereon, the interior of said tubes communicating with the chamber 37. (lil from a suitable source of supply not shown is fed to the generator tubes 38 through oil supply pipes 39. Gas generated in the tubes 38 passes therefrom into the chamber 37 of the manifold 36 through a port 40 for which a needle valve 41 is provided, the latter being mounted in any suitable manner in the manifold 36. Also mounted in the manifold 36 and extending parallel to the generator tubes 38 is a gas reservoir 42, the interior of which communicates with the chamber 37 of the manifold 36. The opposite end of the gas reservoir 42 is secured to another manifold 43 provided with a chamber 44 with which the interior of the gas re'ervoir communicates. A plurality of screw plugs 45 are secured in the manifold 43 and each of said screw plugs is provided with a port 46 for which needle valves 47, 48. 49, 5 and 51 are provided. The needle valves 47 and 48 control the passage of gas from the manifold 43 through tubes 52 and 53 comuiunicating with the members 6 and 7 respectively of the main burner 55, The needle valves 49 and control the passage of from the manifold 43 through tubes 54 and 55 which comn'iunicate with the members 19 and 29 respectively of the auxiliary burner 18. The needle valve 51 controls the pasuige of gas from the manifold 4-3 through the tube 56 to the generator burner 30. Air passage 57 and 5% are provided in the members 6 and 7 respectively of the main burner 5, said patsages communicating with the chamber 10 of each of said members and the gas passing from the tubes 52 and into the chamber 10 draws with it a suitable amount of air from the air passages 57 and 58. Other air passages 59 and 60 are also provided for the members 19 and 20 of the auxiliary burner 18. and said passages are connected by tubes 61 and 62 respectively to the chambers 23 of the auxiliary burner 18, and a suitable amount of air is supplied with the gas passing to the chambers 23 of said burner. A. similar air passage 63 is also provided for the burner 30 and communicates with the chamber 32 thereof for the same purpose previously mentioned.

The general operation of the apparatus is as follow Fo start the operation of the apparatus, it is first necessary to saturate the Wicks 34 with a suitable inflammable material, as for example, kerosene, which is then ignited and said kerosene burns for a sufficient period to pre-heat the generator tubes 38. A suitable fuel oil fed from a uitable source or supply passes through the supply pipe 39 into the generator tubes 38 and staid oil is transformed into a gas upon being subjected to the heat from the burning wicks 34. In starting the apparatus it is preferab e that the valves 47, 48, 49 and 59 shall be closed in order that the first gas generated shall all pass to the generator burner. The gas generated in the generator burner 31) passes from the generator tubes 38 through the ports 40 into the chamber 37 of the manifold 36, thence through the gas reservoir 42 to the chamber 44 of the manifold 43 from which it passes through the ube 5-3 to the generator burner 30. By the time that the inflammable material upon the wicks 3% has become consiuned, a sutticient amount of gas will be supplied to the generator burner 32 to thereafter provide fuel for said burner and after the generator 35 has become heated to a sufficient tempera ture to generate the required amount of gas for the burners 5 and t8, the valves 47, 48, 49 and 50 are opened and the gas permitted to How to said burners.

it will be noted that all of the burners of the apparatus are supplied with their gas and fuel trom the generator 35 and the flow of raid fuel to the various members of the different burners is regulated through the medium of the needle valves 47. 48. 49, 5t) and 51.

It will also be noted that the passage of gas from the generator tubes 38 to the gas memoir 42 may be regulated through the medium of the needle valves 41. The jets of flame pzrsing through the burner tips 13 that are loc: ed in the inclined Wall 11 of the main burner 13 contact with the side wall of the furnace r heater in which the apparatus locaied. while the jet of flame from the burner tips provided in the upper wall of the auxiliary burner 13 conta t directly with the dome portion of the heater. The various burners are adjusted relatively to each other and to the grate of the heater or furnace as required to fit the tire box of the heaters.

It will be understood that all of the burner tips 13 are idcntcal in construction and are provided with a small opening 14 therein, although said openings have been omitted in the various views of the drawings in all but a few instance on account of the very small size and multiplicity of said openings.
