Patented Dec. it), 1929 UNET JOSEPH BRANT, OF HOQUIAM, WASHINGTON AUTOMATIC OIL BURNER Application filed April 27,
This invention relates to improvements in automatic oil burners.
The principal object of this invention is to provide an oil burner which will automatically maintain a boiler at a predetermined temperature thereby eliminating to a la e degree the service of an attendant.
another object is to produce a device of this charact 1' which will automatically operate when pressure is relieved from the boiler for the purpose of raising the boiler temperature to create additional steam.
A further object is to provide means whereby a small name may be maintained at all times.
It still further object is to provide means whereby the device may be readily adjusted to accommodate for varying conditions.
her object is to provide a device this ch racter which will be'simple in construction, and therefore economical to manufac ure.
Other objects and advantages will be apparent during the course of the following description.
In the accompanying drawings forming a part of this specification, and in which llke numerals are employed to designate like parts throughout the same,
Figure I is a vertical cross-section of my burner, and
Figure II is a side elevation of my burner upon a reuuced scale, showing the manner in which the same will be applied to the boiler.
i resent time, it is necessary to maintain an at' sendunt tor the purpose of controlling the flow of oil vapor to the boiler so as to accommodate for various conditions or load, particularly, in the use of a donkey re the same is required to stand idle for various periods and to then be used for a considerable time. This condition may be automa ically taken care of with my burner so that the tendant usually employed can be eliminated.
n the accompanying drawings wherein the purpose of illustration is show a preferred embodiment of my invention, the numeral 5 designates steam cylinder within 1928. Serial No. 273,344.
which a piston 6 is adapted to travel. This piston 6 carries a piston rod 7, the purpose of which will be later seen. At 8 I have shown a cylinder head which is bolted or otherwise secured to the cylinder 5. This head carries therethrough an adjusting screw 9 which is for the purpose of limiting baokward movement of the piston 6.
A pipe 11 extends from the cylinder 6 t0 the source or" steam supply, as for instance the boiler 12 of Figure II. A pipe 13 extends from the cylinder 5 to a point adjacent the throttle which is using steam from the boiler. The pipes 11 and 13 are so arranged that the piston 6 lies between their inlets to the cylinder 5. The cylinder 5 has bolted thereto a frame 16 which is preferably open so as to permit adjustment of the packing glance 17 and 18, as well as the spring tension nut 19 carried upon the piston rod At 21, I have shown a spring which abuts a cross bar 22 carried on the frame 16, and has its opposite end in engagement with the nut 19. The packing gland 18 is formed upon a steam chest 23 whichis also bolted to the frame 16, and has a pipe 24. connecting to the boiler 12 in any convenient manner (see Figure II).
An oil supply cylinder is shown at 26, which is bolted to the cylinder 23 and carries an internal head 27 provided with a valve seat- 28 against which a valve 29 carried upon the piston rod 7 is adapted to contact. An auxiliary valve 31 operated by a hand wheel 32 permits communication from the steam chest to the steam port 33. This steam port 33 is formed through a boss 34 upon which an oil valve 36 is adapted to move. This oil valve is controlled through the medium of a pin .37 extending there- "through and also through the piston rod 7 This oil valve is adapted to engage a valve seat 38 carried upon the end plate 39. The auxiliary oil valve is shown at 41 which is operated by a hand wheel 42 in a manner similar to the hand wheel 32 and permits oil to escape from the oil supply cylinder 26 when desired, as will be later seen.
A burner tip is shown at 43 which tip may be of any desired construction.
At 44 I have shown an oil supply pipe, the purpose of which is obvious. The manner of operating my device is as follows Assuming that the boiler has been fired, and that the same is under normal working conditions, the spring 21 is adjusted by moving the nut 19 upon the piston rod 7 so that the boilerp'ressure will just-overcome the spring 21. As long as the boiler pressure is greater than the pressure of the spring, this pressure conducted through the pipe 11 will push against the piston 6 and will'move the same towards the right of the drawing. This will hold the steam valve 29 upon'its seat and at the same time, will hold the oil valve 36 upon its seat. Consequently, the fire would'go out in the boiler were itnot for the provision of the auxiliary valves 31 and 41.
By opening these valves a limited amount of steam and oil may be conducted to the burner which when properly regulated will be sufficient to maintain the boiler at the proper temperature, when the same is not be- Fng employed.
'As soon as the throttle is open the exhaust therein is permitted to travel through the pipe 13 so as to push against the opposite side of the piston 5 from the steam pressure of the pipe 11, with the result that the spring 21 may now overcome the steam pressure as before referred to, and consequently the valves 29 and 36 will be moved away from their seatswith the result that an increased flame will be projected into the boiler, thus raising the temperature and consequently, maintaining sufficient pressure to perform the work being accomplished.
The bolt 9 provides a means for adjusting the back travel of the piston 6, and its connecting parts. Therefore by adjusting this bolt the'amount of oil and steam delivered to the boiler may be accurately adjusted.
It is to'be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes relative to the shape, size, materialand arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim.
-Having thus described my invention, I claim Ina fuel burner of the character described,
a steam cylinder, a piston movible in said cylinder, limiting means projecting into said cylinder for limiting movement of said piston, means for conducting pressure to the opposite sides of said piston, a rod secured to said piston and projecting through one end of said cylinder, a frame secured to said cylinder, a steam chest secured to said frame and spaced from and in alignment with said cylinder, an oil supply cylinder secured to and in alignment with said steam chest, a head formed between said steam chest and said oil supply cylinder, a boss formed on said head, a port formed through said boss, a cylindrical valve slidably carried on said boss at a point within said oil cylinder and adapted to be moved through the action of said piston rod, a valve secured to said'piston rod and adapted to contact said boss at a point Within said steam chest, an outlet valveseatformed in said oil chest and adapted to be engaged by said cylindrical valve and tension means carried on said piston rod in the manner described.
In testimony-whereof I affix my signature.
JOSEPH BRANT.
