IGNITING APPARATUS FOR BURNERS.
Application filed August 1?, 1925. serial No. 50,548.
flame during the normal operation of the burner.
In accordance with the illustrative embod- 1 iments shown in the drawings, the igniting unit is stationarily mounted in a position where it may ignite fuel delivered to the burner, and a movable shutter, bafile, or other form of protecting member is provided for shielding the igniting device from the heat of the flame during the normal operation of the burner. This shutter or protecting device is adapted to be moved out of operative position so as to expose the igniting unit to the fuel delivered to the burner when it is desired to start the burner, and, after the burner is in operation, the shutter is automatically moved to a position between the burner flame and the igniting unit.
It is to be understood that the present disclosures are by way of illustration only and are applicable to burners of types other than 1 those illustrated. Also, the igniting device, the shutter, and the means for controlling these elements and the operation of the burner, are more or less diagrammatically shown in the drawings, as they are susceptible ofvarious changes, modifications, and embodiments. f I j Other objects will be in part obvious and in part pointed out more in detail hereinafter. T The invention accordingly consistsin the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction; hereinafter set forth, and the scope of the application of which will be indicated in the appended claims. 7 I In the accompanying drawings,.
delivered to the burner,
Figure 1 is a schematic view showing my improvements applied to an oil burning system; g v
Fig. 2 is a vertical sectional view through a portion of the combustion chamber, the protecting shutter, and the igniting unit; f
Fig. 3 is a horizontal sectional view taken on line 3-3 of Fig. 2;
Fig. 4 is a diagrammatic view of another embodiment of my invention; and
Fig. 5 is a view of the shutter.
Referring to that -embodiment of the invention shown in Figs. 1, 2, and 3, of the drawings, the oil burner is disclosed as hav 3 ing afire pot or combustion chamber 10 into which air is forced by a pump 11 through a pipe 12. The pump may be driven in any suitablemanner as, for example, by a motor 13. Positioned within the pipe 12 is a nozzle 14 to which oil is delivered by a pipe 15 from a suitable source of supply.
The igniting unit or element is designated by the numeral 20, and the protectingshuttcr, bafl'le, or member, is designated by the numeral 21. It is, of course, obvious that the igniting unit and the shutter may each take any suitable shape or construction and .may be variously placed either within or without the combustion chamber so long as the objects of the present 'nvention are obtained by positiomng the ifgnitin'g unit so that, when uncovered, it may ignite the fuel and the protecting device is such and so operated as to shield the igniting unit against the fuel and the. heat of the flame during the normal operation of the burner. In the illustrative dis closure of Figs. 1, 2, and 3, the combustion chamber has, at one side, an opening 22 which is adapted to be normally blanked or covered by the shutter 21. ,The igniting unit 20 is positioned adjacent the opening 22 and behind the shutter. If desired, the igniting device may be partially enclosed by a casing or wall 23. This casing, together with the side wall of the fire box, forms a compart- -ment 24 in which the igniting unit is positioned. The, shutter 21 may be guided for f vertical sliding movement in grooves 25.
In Figs. 1, 2, and 3, the igniting element is shown in the form of a rod constructed 'U-shaped metal member 31 carried by the base 30. The shutter 21 is connected to a lever 32 which is normally urged by a spring 33 in a direction to move the shutter to its normal position where it shields the igniting unit. The shutter may be lowered in any suitable manner to expose the igniting unit to the fuel delivered to the combustion chamher as, for example, by means of a solenoid 34, the armature 35 of which is connected to the lever 32.-
The various instrumentalities may be so connectgd up that they are operated in the proper relation or sequence in any suitable manner. In the drawings, these connections are shown, more or less diagrammatically, it being understood that the invention is not limited to the specific arrangement shown. In the present instance, there is interposed in the motor circuit 40, -a thermostat 41 'ftion'. In the event that the temperature of the room drops below a predetermined de- .55
which may be located in the room, the temperature of which is to be controlled. It may be assumed that this thermostat will close when the temperature of the room drops to a'pred'etermined degree, and will automatically .open to break the circuit and throw off the .motor when the temperature of the room rises above-a predetermined de'-. gree. The solenoid 34 and the heating unit 20 are connected in series with-each other and in parallel with the motor. Interposed in the circuit, which includes the solenoid and the igniting unit, is a thermostat 43 which is adapted to be affected by the heat of the burner flame in such' manner as to" break the circuit through the solenoid and the igniting unit after the fuel has been ignited. This thermostat. 43 may be positioned in, or may extend above, or be placed in close proximity to, the combustion chamher so as to be heated thereby.
The operation of the arrangement. de-
scribed is, briefly, as follows: Assuming that the room containing the thermostat 41 isat the desired temperature, this thermostat will be open and the burner will be out of operagree, the thermostat 41 will close with the result that the current will pass through the motor and the latter to force the fuel 1nto the combustion box. The current will also, pass through the solenoid 34. and the lignit-' ing unit whereupon the former willldraw the [shutter down, the igniting'unit will be'heated to incandescence, and thefuel delivered to 5 the combustion box will be ignited.- After the fuel has been ignited, the thermostat 43 will be heated with. the result that the circuit through the solenoid and the igniting element will be broken whereupon the spring 33 will move the shutter to the normal position shown in the drawings. Now, during the normal operation of the burner, the shutter protects the igniting unit so that there is no" possibility of it becoming burned out. When, after continued operation of the burner, the temperature of the room within which the thermostat 41 is positioned rises to a predetermined degree, this thermostat will open, with the result that the motor will be thrown out of operation and, as there is no longer a flame within the combustion chamber, the thermostatic device 43 will cool off and close the contacts associated therewith. The parts will now remain in the con-- dition shown in Fig. 1 until the thermostat 41 again closes.
In the embodiment illustrated in Figs. 4 and 5, the shutter 21' is adapted to close an opening 22 in the pipe 12 through which air is forced by a pumpll, driven by a motor 13'. 14 is the fuel nozzle. Above the opening 22 is an igniting unit 20 partially enclosed by a casing 23. The shutter is pivoted, as at 50, and has a cutaway portion 51. The shutter also has an arm 52 and may be actuated by a lever 32 in the same manner as was the shutter of the previous embodiment. hen it is desired to ignite the fuel the shutter will be moved to the full line position shown in Fig.3. 4, and the fuel will be deflected into contact with the igniter and then pass through the opening 51, as illustrated by the arrows. After the fuel is ignited the shutter will be automatically brought to the closed position shown by dotted lines of Fig. 4.
What I claim is:
1. In combination, an oil burner having a I conduit through which fuel is delivered to a combustion chamber, a compartment outsideof said conduit and between the ends thereof, said conduit having an opening through which it may communicate with said compartment, an igniter in said compartment adapted to be heated to 1ncandescence by an electric current passing therethrough, and a shutter adapted to close said opening and when in open positlon to deflect part of the fuel into said compartment and into contact with said igniter.
