OIL-BURNING SYSTEM.

Specification of Letters Patent.

Patented April 30, 1907 "To all whom it may concern.-

Be it known that we, MICHAEL N. MAC- RATE and JOHN A. TOOMEY, both citizens of the United States, and both residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Oil-Burning System, of which the following is a specification.

This invention relates to oil burning systems and particularly to a system in which the oil is forced under pressure to the burner and one of the main objects of the invention is to cause the supply of oil to be automatically cut off in the event of the burner becoming accidentally extinguished or if the burner valve is carelessly left open and the burner has not been lighted.

Another object is to provide means for filling the main storage tank without the necessity of putting out the fires at the burners.

A further object is to provide a safety drain and receptacle for any oil which may escape from the burner.

Further objects of the invention will be brought out in the following description.

The accompanying drawings illustrate the invention, and referring thereto :Figure 1 shows the preferred arrangement of the system, the automatic safety oil shut-off device being shown in section. Fig. 2 is a side elevation partly in section of one form of burner. Fig. 3 1s a section on line m a; of Fig. 2. Fig. 4 is a vertical sectional view, enlarged, of the automatic safety shut ofi valve and adjacent mechanism. Fig.5 is a view of a ortion of the system showing a modified orm. Fig. 6 is a detail section through the four way valve.

1 desi nates the main tank to which oil is delivere by a pipe 2 which may extend to the street or other place convenient for filling from car or tank wagon, the valve 3, when closed, prevents the outward passage of'oil when the main tank is under water pressure. A pi e 4 leads from the main tank 1 to an auxi iary tank 5, the pipe 4 having a valve 6. The pipe 7 extends from the lower art of the tank 1 to a four way valve 8, Whi e a pi e 9 leads from valve 8 t0 the auxiliar tan 5. A water pipe 10, which is connecte with the city water system, leads to valve 8, the pipe 10 being provided with an automatic pres sureregulating valve 11, for maintainin the pressure at any desired degree, and wlth a safety valve 12 WhlOh prevents any excessive pressure in the event of failure of the pressure re lating valve 11 to act properl and locate between the safety valve 12 an pressure re ulating valve 11 is a manuall operated va ve 13. The pipe 9 is provide with a check valve 14 which prevents the backward flow of oil through pipe 9. A drain pipe 15 extends from the valve 8 to a sewer or drain 16 which may be located either above or below the main tank 1. Mounted on the respective stems of valves 6 and 8 are levers 17 and 18, the latter being provided with a han dle, and the two levers are connected by links 19 so that when. the hand lever 18 is operated to shift the valve 8, the lever 17 is also simultaneously operated to automatically open or close the valve 6.

A pipe 20 extends from the auxiliary tank 5 to an automatically controlled valve 21, shown in detail in Fig. 4, which is located within a casing 22. The stem 23 of the valve carries a laterally projecting arm 24-, which arm is connected to a spring 25, the other end of the spring beingv attached to the casing 22. The lower end of] the arm 24 is extended slightly beyond the stem 23 to form a detent 26, which detent is normally engaged by a ivoted latch lever 27, the outer end of the ever 27 being connected to a float 28, the casing 22 having a semi-spherical pocket 29 formed in its lower wall to receive the float. The latch lever 27 normally engages the detent 26 and holds valve 21 open, but when any oil escapes into the pocket 29 the float 28 is lifted which disengages the latch-lever 27 from the detent 26 and the spring contracts and automatically closes the valve 21 which remains closed until the valve is manually retracted and re-engaged with the latch lever 27. A pipe 30 leads from the valve 21 and oil burners 32 may be connected therewith.

One form of oil burner which may be used is shown in detail in Fig. 2 and com rises a cylindrical retort 33, the interior 0 which may be filled with fire brick 34 broken 1nto small chunks. A pipe 35 conducts 011 from the pipe 30 to one end of the retort 33, while a pipe 36 leads from the other end of the retort down to a burner tube 37 which is formed on a pan 38 located under the retort 33, the upper wall of the tube provided with. orifices for the escape of gas to be'burned From each pan 38, a ipe 39 leads to the casing 22 above described Each pipe 35 is provided with a valve 40 for regulatingthe burner. The drain pipe is arranged to conduct any excess of oil from the casing 22 to a recep-.

is shut and lever'lS is operated to shut oil communication of pipe 7 with pipe 15 and pipe 7'and pipe to sewer 16.

tank 1 has been refilled withoil, valve 3 is .-is aga1n under the water pressure.

valve 6 is simultaneously opened so that 1 after tank l is filled oil will flow into the auxiliary tank 5. As soon as both tanks are filled, the valve 3 isclosed and as pipes 10 and 7 are in communication and valve 6 is open, by opening valve 13 water under pressure passes through pipe 10 to pipe 7 and into the lower part of tank 1, thus placing the oil'in both tanks 1 and 5 under the pressure of the water which forces oil up through ipe and through valve 21 to pipe 30, ii'om which the oil is delivered through pipes to the respective burners. enters-the retort 33 of a burner is formed into gas or vapor by the heat from the flames which are burning under the retort and the gas generated in the retort is conveyed water pressure while the main tank 1 is being filled and to 'accom lish this the lever 18 is operated to close va ve 6 and place pipe 10 in communication with pipe 9, and to place pipe 7 in communication with pipe 15, whereupon the pressure from the water in pipe 1.0 is transferred directly to the auxiliary tank 5 through the pipe 9, the check valve 14 permitting the movement of water in this direction and-thus the burners are kept su plied with oil under the same pressure whi e the tankl' isbeing refilled. In refilling the tank 1, the valve .3 is opened and the pressure of'the oil in entering forces the water which has accumulated in the tank 1, out through As soon as shutandlever 18 is opened to open valve 6 and again place pipe 10 in communication with pipe 7, whereupon the oil in both tanks Water which gets into tank 5 during the refilling operation, sinks down through pipe 4 into tank lassoon'as valve 6 is opened afterthe completion of the refilling operation.

a it through carelessness or ignorance 01'- accident, aburner is out and its valve 10 is open the oil which escapes from the burner will' flow through pipe39 into the casing 22, and but a slight amount of oil thus escaping is necessary to lift the float 28, whereupon the latchlever; 27 releases detent 26 and allows the valve 28 to quickly shut tight, which positively prevents further flow of oil to the burner'and thus prevents accident.

The oil, as it What little excess of oil may be present in' the burner andcasing 22, after the valve 21 closes," finds its way out through pipe.45

and is caught by receptacle 46.

Fig. 5' shows another form of connectionin which automatic co-operation of valves 6 and 8 is dispensed with, and a valve 8 is substituted i'or valve 8, and a plain check valve substituted for the valve 6. When the valve 8 is in one position the pressure isthrough pipe 7 into the tank 1, forcing the oil from tankl up ,past valve 50 into tank 5 and'thence to the burners, while when the valve 8 is in the other position, communication is shut ofl between pipe 10 and 7 and pressure goes from pipe 10 through pipe 9 to auxiliary tank 5. At the same time pipe 7 is in communication with pipe 15 so that water from the tank 1 may pass through those pipes to the sewer.
