Application fiieam ire; 192 9. semrmeamw -My: invention 'lrelatesto: improvementstin automatic opening and closhag furnac'ed-oorsfor automatic oil burners; and it consists in the combinations,constructions and 'arrangee ments hereinafterdescribed and claimed;
In the' standard type of automatic oili burner, the oil atomizer projects a slight distance intothe furnace Sowlong as the burner functions, I practically all 0f the oil is burned: Eachitimeth'e burner: is stopped ,l. a fewndrops of oil flowitoxthe-rim ofwthe 'oili atomizer.- The heat"within the furn ace isat I a very high temperature, and is sufficient to carbonizethe oil on. the atomizer, In: time, a ring of carbon is gbuiltiup: upon: the rim of. the atomizer, and it 413 :necessary; to remove? this carbombefore thedevice willg function efficiently'. V
The principal Iobj ectof' my invention is: to I automatically =1nove. a: heat resisting shieldbetween the furnace and the burner-so esto prevent the intense heat within. the funnace from carboniz'ing thezoil on. the burner. This: shield. is automatically moved away fromth'ei' furnace I door opening when: th'eburner starts functioning In: this =wayxth'e-heat+resisting f shield needs vno attention from ram-operator, L but will automatically; function with. ther'oiL burner; v
In the: present drawing 1 :havezshown: the shield as being controlled by :the oilpressure It is obvious that'iiti could. :be controlled by other means, and I therefore do not wish to be confined to the particular type of showing.
Other objects and advantages will appear as the specification proceeds, and the novel features will be particularly pointed out in the appended claims.
My invention is illustrated in the accompanying drawing, in which Figure l is a schematic view of an oil burner and furnace showing my device operatively applied;
Figure Q is a section along the line 2-2 of Figure 1; and
Figure 3 is a detail section through a part of the device.

A pipe "15 leads :from: the pipe-B to a ioylini-i der 16(see Ffigunei2) Apistonlli'v is'inountedo in the cylinder and is connected ,by aalinkl 189 to: an' armil9. The; arm'rinitunnxisscarried by a shiaft 20 and: carriesiza second: arm QI'athat supports: a- :heat resistingi doon 22 fmadexofi? asbestos-or other'suitable material? The doon: is swingable' i from a :posi 'i onucovering thei opening5l'intora:position2 above atlie opening, W as shown-by the dotted lines-imFi'gureQfi Fromm the fo'regoing': description of the r' various parts of the: device-{theuoperation c thereofinay berea-dily understood 7 As 'soon as the; burner tstants": functioning," 9 oilfis aforced into the pipes 7,18, '13 and 15.1; The 5 valve =11 controls J-th amountfofi oil: p assinge from the pipe 8 into-the pipelQH. The valvesl ler contmols-: the 511110111117; .cofioi'lr rbyap assin'gu the valve 12:. The ramountioffloil isiexceedingly'v small so as to not overwork the pump 2 in merely forcing oil through the by-pass. The valve 12 causes the oil within the pipe 8 to reach a pressure of twenty-five pounds, for example, before it will open and permit the oil to flow into the pipe 10. This pressure of oil builds up in the pipe 15 and in the cylinder 16, thus causing the door to swing open. So
long as the pump functions, the oil within the 19 cylinder will keep the door 22 open.
When the burner is automatically cut off and the oil pump stopped, the oil within the pipes 7, 8 and 15 will drain through the bypass 13. This will permit the piston 17 to lower and to move the door 22 into closed position. The door prevents the heat from the furnace from striking the oil atomizer 4, and this prevents the carbonizing of the oil on the atomizer. The door 22 will be instantly swung into open position as soon as the burner again starts to function, and this opening and closing of the door automatically takes place each time the pump 2 starts and stops functioning.
25 Although I have shown and described one embodiment of my invention, it is to be understood that the same is susceptible of various changes, and T reserve the right to employ such changes as may come within the scope of the invention as claimed.
I claim:
1. The combination with an oil burner and a'source of fluid pressure therefor, of a protective shield movable into a position in front of the burner, and means controlled by the fluid pressure for moving the shield away from the burner when the burner starts operating, and in front of the burner when it stops for preventing carbonization of oil on 40 the discharge nozzle of the burner.
2. The combination with an oil burner having an oil force feed pump, of a protective shield disposed in front of the burner when the burner is inactive for preventing carbonization of oil on the discharge nozzle of the burner, and means actuated by a portion of the oil delivered by said pump for moving said shield away from the front ofthe burner.
3. The combination with an oil burner, of means for delivering oil to said burner, a shield disposed in front of the burner when the latter is inactive for preventing carbonization of oil on the discharge nozzle of the burner, and oil-actuated means for moving said shield away from the front of said burnor, said last-named means functioning when said oil-delivering means is actuated.
4c. The combination with an oil burner,
of means for delivering oil to. said burner: a return pipe for carrying away the unused oil, a shield disposed in front of said burner when said oil delivery means is inactive, and
oil-actuated means operatively connected to said shield for moving it away from said burner when said oil delivery means is actuated, the oil from said oil-actuated means draining into said return pipe when said oil delivery means becomes inactive, whereby said shield is returned to a position in front of the burner for preventing carbonization of oil on the discharge nozzle of the burner.
5. The combination with an oil burner, a fuel pump, a return pipe, and a valve disposed in said return pipe, of a shield swing- --v able from a position in front of the burner to one away from the burner, a cylinder having a piston actuated by the oil delivered by said pump, connections between the piston and the shield for moving the shield away from the burner when oil is delivered to the cylinder, and a bypass connecting the cylinder directly with the return pipe for draining oil from the cylinder and allowing the shield to return for preventing carbonization of oil on the discharge nozzle of the burner.
6. The combination with an oil burner, a fuel pump, a return pipe, and a valve disposed in said return pipe, of a shield swingable from a position in front of the burner to one away from the burner, a cylinder having a piston actuated by the oil delivered by said pump, connections between the piston and the shield for moving the shield away from the burner when oil is delivered to the cylinder, a by-pass connecting the cylinder directly with the return pipe for draining oil from the cylinder, and allowing the shield to return for preventing carbonization of oil on the discharge nozzle of the burner.
7. The combination with an oil burner and a source of fluid pressure therefor, of a protective shield movable into a position in front of the burner, and means entirely and automatically controlled by the fluid pressure for moving the shield away from the burner when the burner starts operating, .and in front of the burner when it stops for preventing carbonization of oil on the discharge nozzle of the burner.
