To all whom 'it may concern." j

Be it known that I, CHARnEs H. BURR', a citizen of the United States, residing at Orizaba, State of Vera Cruz, Mexico, have invented certain new and useful Improvements in Oil-Burning Apparatus, of which the following 'is a specification.

This invention as specified `relates to new and useful improvements in oil burning ape paratus.

The object of the invention is to lprovide an apparatus comprising a burner located at the front end of a tire box fed by steam and oil pipes the latter of which passes through a ,super-heater and leads 'from a storage tank in which the oil is heated and placed under pressure.

' Other objects of the invention are the provision of means for cleaning the oil pipes and the burner; and the provision of a safety d `ice whereby the supply vof oill from the oil tankis automatically cut off in case of fire. l,-

A still"`. t,"artherl object ofthe invention is to provide an apparatus of the character described that will be strong, durable, efficient and simple and comparatively inexpensive to produce, also one in which the several parts will not be likely to getj out of working order. v

lfith the above and other objects in view, the invention has relation to certain novel -features of construction and operation, an

example of which is describedin the following specil'lcation and illustrated inthe accompanying drawings, wherein:

Figure 1 is a diagrammatical View of thel oil burning apparatus. Fig. 2 is a horizontal cross-sectional view on the line W-W of Fig. 1I Figf 3 is a horizontal cross-sectional view on the lineX-X4 of Fig. 1

Fig. bis afdetail of the super-heater. Fig. 5 is a detail of the burner and adjusting means. Fig. 6 is afront elevation of the burner. Fig. 7 is a plan view of the burner.

Fig. 8 is a section on the line Y-Y of Fig. 7 and Fig. 9 is a cross section on's the line Z-Z of Fig. 7.

In the drawings the numeral 1 designates the fire box of'a boiler furnace, 2 the front end and 3 the rear end. As shown in Fig. 2 an opening 4 is provided in the rear end of the fire box. In this opening a burner ^is horizontally disposed. As shown in Fig.

5 a yoke 6 is fixed on a bracket 7 secured to thek outer side of one end of-.the firev box l which we will call the rear-end; 'Trunnions 8 are journaled in 'ithe upper ends of the yoke V 6. A pair ofv adjacent ears 9 "project-horizontally froml the outer end of the burner and pivotallyreceive the upper end Lof an eye rod 10 as shown in Figs. 5 to 9 inclusive.

The lower end of the rod 10 passes through a plate bracket 11 secured to the under side of the lire box. The eye rod is screw threaded and receives nuts 12 `bearing ony opposite sides of the bracket 11. By' adjusting these nuts the burner throughv the agency of thev rod is swung on its-trunnions and its angle of inclination with relation to a horizontal plane varied.

The trunnions 8 have central passages 14 and 15 respectively extending transversely of the burner and communicating with the chamber 19 within the burner. The chamberl is divided into two compartments by a transverse web 16 of irregular contour and an extension 20 of this web separates passages 17 and 18 extending longitudinally of the burner as shown in Figs. Sand 9. The passage 15 admits oil Ainto the chamber 19 which is deflected by the web 16 into the passageV 17; while steamadmitted through the pas# vsage 14 to the chamber 19 is deflected by the web 16 into the passage 18.

The oil is discharged from the inner end of the burner by way ofthe passage 17. The

steam passage 18 is b'elovsT the oilpassage 17 and has its discharge end contractedfand partially closed by a nozzle plate'21 removably set into the end ofthe burner. The

plate 21 may be renewed when .worn or'- burned out. aThe opening for-the/discharge of steam is 'restricted whereby the ,steam is ejected in a fine spray and mixed with the oil at the point of combustion. By observing Fig. lit will be noted that the burner is located at the rear end of the rebox and that at the front end of the fire box a brick wall 2 is provided which acts as a target andv against which the .steam and oil'-.are ejected. ISufficient space for admittingair is lleft around the burnervin the opening 4 but additional air openings 22 may be provided in the Wall 3 if desired Where the burner is applied to a'locomotive boiler the end 3 would be toward the front of the locomotive and the end 2 at the cab.

A very important feature of the inveny tion is the meansand .apparatus foriv plying steam and superheated oil to the pipe 31 to the passage 15' of the burner and burner. This apparatus'comprises a storhas included therein a controlling valve 47.

age tank 25 in which a heating coil 27 i'sv Suitable connection is made between the supported above the bottom.

Exhaust steam from a superheater 41 is conveyed b a pipe 42 to a branch pipe 28 which leads through the bottom of the tank to the coil. Steam from thecoil is conveyed by a short pipes 29 and 46 and the burner whereby the 65 y latter may be swung. Superheated oil is highly combustible and is of great advantage in an oil burner.

For the purpose of cleaning the pipe 31 pipe 42 tothe pipe 42 at a point. above the the pipe 46 and the passages 15 and 17 of 70 pipe 28. It is not always necessary to use the heating coil but when ,itis used a val-ve 60 located in the pipe 42 between the pipes 28a and 42a. is closedvwhereby the exhaust steam from the superheater is circulated through the coil. When it is desired to cut out the heater the valve-60 is opened and a the burner, a pipe 48 leading from the live steam pipe 28 is connected to the pipe 31. A Valve 49 is mounted on the pipe 48 for cutting ofi" the passage of steam to the pipe 31. Between the pipe 48 and the tank 25 a valve 75 50 is mounted in the pipe 31. Then it is desired'to clean the parts 31, 46, 15, and 17 valve 61 located inthe pipe 28a is closed the valve 50 is .closed and the valve 49 is thus permitting the exhaust steam to escape opened thereby live steam will flow through throughv the pipe 42 to atmosphere.

The the pipes 31 and 46 and the passages 15 and 80 heating coil maintains the oil in a flowing 17 thus removing any deposits or obstruccondition. A steam pipe 26 leads from the tions and cleansing the oil outlet of the boiler to a pipe 28 which terminates in a .burnerpipe 29 leading to the passage 14 of the burner and in which a controlling valve 30 25 is included.

An oil pipe 31 leads from a valve in the bottom of the oil tank. The valve 32 has a .C iring" pressed rod extending through the to of so by the spring.
