SPECIFICATION formingpartl of Letters Patent No. 736,563, dated August 18, 1903.

Application filed October 27, 1902. Serial No. 129,038. (No model.)

To @ZZ 'whom t may concern:

Be it known that I, ALFRED CLEMENT STEW- ART, a citizen of the UnitedV States, residing at Santa Paula, in the county of V cntura and State of California, have invented a new and useful Automatic Regulator for Liquid-Fuel Burners, of which the following is a specification.

An object of this invention is to provide a device adapted for automatically regulating the flow of oil and air or steam to a hydrocarbon-burner of the atomizing type, the same being adapted for successful operation with heavy oils carrying solid impurities and being self-contained and not liable to get out of order. This device comprises a body having two ways'and valve-seats therein, valves for said seats, arod for operating said valve, means for yieldingly holding the valves open, and fluid-controlled means to operate said rod for closing the valves. Said rod is desirably arranged for positively opening said valves and for positively closing one of said valves only, means being provided for yieldingly forcing the other valve toward its valve-seat and fluid-operated means being provided for operating the rod for closing the valves. By making the valves operate independently of each other, so far as their positive closing is concerned, it is possible to provide for more simple construction, an d the oil-valve ismade more accessible for cleaning.

The invention relates to the construction and arrangment of the entire device and of portions thereo f, as will be more fully understood by the accompanying drawings and the following specification.

Another object of the invention is to provide for maintaining correct proportions between the steam or other atomizing fluid and' oils of different gravities, and this is done by providing interchangeable valve-seats for the oilway.

The accompanying drawings illustrate this invention.

Figure I is a general view showing my regulator in use with an atomizing hydrocarbonburner of any desired construction. Fig. II is a detached elevation of the regulator viewed from the left in Fig. I. Fig. III is a plan of the same. Fig. IV is an axial section "on line IV IV, Figs. II and III, looking left.

Vis a plan section on line V V, Fig. IV. VI is a plan section on line VIVI, Fig. Fig. VII is a detail of a set of removable interchangeable valve-seats for the oiloutlet 4, and a valve-seat 5 therebetween. 6

is a perforated head for one end 7 of said member, the perforation S thereof communicaiing with the opening 9 in said end through a nipple 10, by which said head 6 is desirably connected with the member 1. 11 is a duplex diaphragm. 12 is a diaphragm member fastened at its center to said head 6 and having a perforation 13 communicating with said end opening i). 14 is a second diaphragm member fastened at its edges to the first diaphragm member. 15 is a second head fastened to the second diaphragm member, at the center thereof. 16 is a valve for said valveseat 5. 17 is a valve-rod connecting said second head 15 with the valve 1G. The purpose of the heads is to reinforce the diaphragm members and prevent their rupture.

1S and 19 designate means for yieldingly collapsing the double diaphragm, and thereby holding the valve 16 open. Said means desirably comprises aspiral spring and the yoke 19, which has a boss 20, engaging the head 15, and having a socket 21, in which a projecting portion 22 of the valve-rod 17 extends, thus to prevent the yoke from lateral or endwise displacement. The way 2 is desirably for the expansive fluid, as air or steam, by which the atomizer 23 is operated. The expansive fluid will be supplied to the inlet 3 by means of a pipe 21 from the steam-boiler 25 in case steam is used or from any suitable intermediate means (not shown) operated by steam-pressure from said boiler. It is deemed sufficient for the explanation of this invention that it be illustrated simply as connected by the pipe 24 with the boiler 25, so that as the steampressure rises in the boiler the diaphragm 11 will be distended by the steam, thus forcing the valve 16 down toward the valve-seat 5, thereby closing partially or wholly the orifice through which the liuid may pass in way 2. 26 is a second open-ended member fastened to said iirst member 1 and having a perforation 27 communicating with the way 2 of said ICO iirst member and also having an inlet 28 and outlet 29 and a valve-seat 30 therebetween. 31 is a pin fitted in said perforation 27 and forming an extension of the valve-rod 17 32 is avalve for said second valve-seat 30, and 33 a valve-stem therefor operated by said pin 31 and forming a further extension of said valve-rod 17 34 designates means for yieldingly seating said second valve 32. 35 is a closure for that end 36 of said second member which is opposite the diaphragm. Said closure is desirably a cap having a screwthreaded portion 37, which screws into the end 36 of the member 26.

33 is a guide for the upper end of the valvestem 33, the same being desirably a socketed boss projecting in from the cap and around which the spiral spring 34 isv mounted and by which it is held in place. The upper end of the valve-stein 33 is desirably smooth and plays freely back and forth in the socket 39 of the boss 3S.

The valve 32 is ydesirably provided with an angular boss 40 and is internally screw-threaded to screw upon the screw-threaded portion 41 of the valve-stem 33.

42 is a j ani-nut by which the valve 32 is fixed Y at any desired place on the valve-stem 33.

43, 44, and 45 are interchangeable valveseats for the oilway 46.

47 designates screws by which the requisite oil-valve seat will be fastened in place in the oilway.

48 designates rivets fastening the diaphragm member 12 tothe first head 46. Desirably the second head 15 is screwed onto the lower en d of the valve rod 17 and is then fastened permanently by battering or riveting the rod 17 thereon, as indicated at 49 in Fig. IV.

50 is a shoulder desirably in the form of a jam-nut, which is fixed on the valve-rod 17 The valve 16 is desirably screwed on the upper end of the valve-rod 17 and then locked by a Cotter-pin 5l.

52 is a socket in the .inner end of the valverod 17 to seat the lower end of the pin which serves as a center for the stem 7 to hold the valve true relative to its seat 5. Desirably the valve-stem 33 simply abuts against the upper end of the pin 3l.

53 and 54 are the valves for controlling the supply of expansive iiuid and oil, respectively, to the inlets 3 and 2S.

The members 1 and 26 are readily detached from each other, being desirably fastened together by the screw-threaded boss 55 on the member 26, screwed into the upper end of the member 1, and when thus fastened together the two members form a practically unitary body having the steamway 2 and oilway 46 therein.

In practical operation the steam acting on y the inner sides of the diaphragm members same time the spring 34 forces the valve 32 toward the valve-seat 43 and the valve-stem 33 impinges on the pin 31, which is supported by the valve-rod 17.

In adjusting the appliance for practical use the valve 32 will be screwed' onto the valve-steml 33 to such a point that when the valve 16 is seated the valve 32 will be held slightly above its seat, so as to allow sufficient oil to pass through to maintain a pilot-light at the burner. 56 designates a vent in valve 17 to allow a small amount of. expansive fluid to pass through the way 2 when the valve 16 is fully seated, thus to at all times maintain the pilot-light at the burner so long as the.

fuel is not shut off by the supply-valve.

The interchangeable valve-seats 43, 44, and 45 are respectively furnished with orifices a Z) c of different sizes. readily the valve-seat having a smaller-size orifice will be employed, while for thick oil a valve-seat having a larger orifice will be employed. By this arrangement the operator* may adjust the appliance for satisfactory use of any determined oil. When the valve is at any determined point above its valve-seat, the effective area of opening for the passage of oil will be determined by the circumference of the opening in the valve-seat and the distance between the valve and its seat, said opening being increased ordecreased relative to the steam-passage at 5 by applying the valve-seat 43, 44, or 45 having the larger or smaller opening, as required.

Some oils are so thick that they will scarcely flow through a one-inch pipe, whereas other oils flow almost as freely as water. Consequently it is necessary in some instances to provide for a very large opening through which the oil may iiow and in other instances a very small opening, while the flow of the expansive fluid is simply determined by its pressure regardless of the consistency of the oil.

In constructing a regulator from the manufactured parts the same are assembled as follows: The upper member 12 of the diaphragm is riveted to head 6. The lower member 14 is then placed against it and their edges lturned together to form steam 01 air tight joint. The jam-nut 50 is then screwed on rod 17 and the lower end of the rod passed through the hole of the lower member of diaphragm and screwed into the lower head 15,

thus clamping the diaphragm tightly between the jam-nut 50 and said head 15. Then the rod will be riveted, as shown at 49, a sufficient portion of the rod projecting beyond the head 15 to form a guide for the yoke 19. The upper head- 6 is then screwed to the steam .body 1 by means of the nipple 10. The valve 16 is'screwed upon the top of the rod 17 and fastened by a split key 51. The oil member 26 is then screwed into the upper end of steam member 1. Removable valveseat 43 is then fastened in place by means of screws 47.

Pin 31 is then placed in hole 27.

For oil which flows IOO IIO

The oil-valve 32 is then screwed on valvestem 33 and jammed in place by jam-nut 42 and then placed on valve-seat 43. Then spiral spring 31 is placed upon valve 52 and then cap 35 is screwed in place at the upper end of the oil member. Then the springs are secured in place by eyebolts 57, passed through lugs 5S, which project from the body of the appliance, and nuts 59 are screwed on the ends of the bolts 57 and against the lugs 58. Then the yoke 19 is brought in position below the head 15 and the ends thereof are caught into eyes (50 at the lower ends of the springs 18. Then the nuts 59 will be tightened to appropriate tension to normally hold the diaphragm collapsed and the valves open.

Access to the interior of the oilway and to the valve for the purpose of cleaning the same or removing any obstruction may be had by unscrewing the cap 35, thus allowing all of the parts pertaining to the oil member 26 to be removed without disturbing any of the other parts.
