2 Claims.
My invention relates to an improvement in controls for oil burners and is particularly applicable to pot type burners.
It has for one purpose the provision of means for completely cutting on the suppl of oil in the event that the fire goes out.
Another p se is the provision of improved control means for valves of a fuel supply control means particularly adapted for use with a burner in which a pilot flame is localized at one point in the burner.
Other purposes will appear from time to time in the course of the specification and claims.
I illustrate my invention more or less diagramfiatically in the accompanying drawing where- Fiu. 1 is avertic'al section;
Fla. 2 is a section of the valve structure on an enlarged scale, closed position;
Fig. 3 is a partial shown in Fig. 2;
Fig. 4 is a section on the plan view of the structure line M or Fig. 2:
Fig. 5 is a similar section with the parts in a diflerent position;
Fig. 6 is a similarsection with the parts in a still difierent position; and
Fig. 7 is a side elevation of a variant form.
Like parts are indicated by like symbols throughout the specification and drawing.
Referring to the drawi I illustrate a burner pot i having a side wall 2, provided with primary air inlets 3 located at various levels. I may employ any suitable means for supplying secondary air. I illustrate a row of secondary air inlets t adjacent the top of the pot t. t is any suitable flame ring for the top of the pot, having a corn The pot is supported on a flange or ring i, extending inwardly from any suitable outer housing or drum t, the upper portion of which above the pot may provide a combustion chamber. Eeiow the pot the drum d has a bottoms, with an ah inlet aperture it, through which air may be admitted to the space between the pottend the drum t. I I
Any suitable supporting means may be employed for the structure, it being understood that the space below the partition d is open to the atmosphere or is in communication with some supply me.
is a pi vs, i generally indicates a liqu d n P h ying a nozzle portion hie securing il -1 In lot piece, herein shown as a fol-am with the valve illustrated in c1. lac-42.4)
communication with the. fitting it is the fuel line It, extending from a flmt chamber generally indicated as ll. 'li'he fioat chamber It is shown as including a filter chamber it, with a filter it therein. i911 indicates a liquid inlet line from any suitable source of liquid fuel not herein shown.
In communication with the filter chamber is a liquid fuel inlet passage 2%, with its valve seat member ii. 22 is a valve stem movable toward and away from the seat 2!, mounted for exam- 7 ple in the sleeve it, with the fuel outlets it, the sleeve in this instance being made unitary with the valve seat. 26 is any suitable float, pivoted on any suitable pin it and having a portion 27 at the opposite side of the pivot, engaging a washer or flange it on the valve stem, which is normally upwardly urged as by the spring 29.
it indicates the fuel in the float chamber, and itwill be understood that the level in the float chamber is governed by the fioat it, which as it is raised by the fuel it tends to close the valve stem 22 and reduce or cut ofi the flow oi fuel through the passage it. Within the float chamber is an intermediate partition it, which divides the interior of the fioat chamber into two compartments. In one compartment is located the above described fioat 2t, and in the other a supplemental heat it, secured as at 3V to a lever it, pivoted as at it, and having an end portion it extending outwardly through a slot ti in the side of the float cber structure. It also has an abutment portion it adapted to be opposed to the top of the stem it of the valve stem 22.
In the event that the float it or the valve it become stuck, or ii for any reason the fioat structure does not function, iuel may overflow the partition as and raise the float it, thus depressing the portion t2 and closing the valve.
However, in my invention I employ a lever 38, or its equivalent, to permanently cut oh the liquid fuel in the event that the burner goes out. For this purpose I provide any suitable l perature responsive member, which is located adiacent the pilot piece i t. I illustrate, for example, a thermo-bulb it connected by a hollow tube 56 to a bellows iii, mounted on the top of the float chamber it. Normally, when the burner is on and the pilot flame is burning, the beiiows ti' is in the expanded position in which itis shown in Assume that the burner is on and a supply of fuel is flowing. The arm I is out or contact with the lever 40 and performs no function. It, however, the pilot flame goes out and the pot becomes entirely cold, then the bellows ll collapses to the position in which it is shown in Figs. 2 and 4, and the arm 49 engages the end of thelever l! and thrusts it down into the valve closing position in which it is shown in Fig. 2, thus closing the valve 22 and preventing anyi'urther supply of fuel to the float chamber along the passage "a, entirely independent of the operation of the floats 25 or 36. Thus, the supply of fuel to the pot is shortly cut oil, as no further iuel passes to the float chamber.
It the operator wishes to re-light the burner and wishes a supply to the burner in preparation for re-lighting, he moves the arm 49 laterally to the position in which it is shown in Fig. 5, which permits the lever 38, 40 to move to I release position and permit fuel again to flow into the float chamber. As soon as the burner becomes heated, then the bellows 41 is again in the expanded condition of Figs. 1 and 6, and the control device is again ready to function, as the arm 49 rotates by gravity back into the position in which it is shown in Fig. 6.
Referring to the modified form of Fig. 7, in place or having the support 48 on the top 01 the bellows, I employ a separate abutment 50, to which the lever 48a is pivoted, it being normally urged downwardly by a spring SI of insuflicient force to resist the expansion of the bellows 41. The arm 49a is then loosely pivoted to the end of the support or lever 48a, and the operation or the device is the same.
It will be realized that, whereas I have described and illustrated a practical and operative device, nevertheless many changes may be made in the size, shape, number and disp sition 01' parts without departing from the spirit or my invention. I therefore wish my description and drawing to be taken as in a broad sense illustrative or diagrammatic, rather than as limiting me to my precise showing.
iorly oi' the float chamber and adapted for manual resetting, and an arm adapted to engage said in said chamber adapted to control said valve,
and means independent of said float for movin said valve to closed position, including a valve controlling element extending to the exterior of said chamber, an expansible member mounted on the exterior oi said chamber, and means for normally maintaining it in expanded position, including a fluid system in communication with the interior or said expansible member, one element of said fluid system being located adjacent. the burner and being responsive to the heat oi said burner, a member supported on and pivoted to said expansible member and normally gravitally aligned with said outwardly extending valve actuating member and adapted, when the contents oi the liquid system becomes cool, to engage said actuating member when the expansible member on the float chamber contracts, and to close the valve.
