2 ll aimed (01. 137-153) The herein described invention relates to'automatic damper regulators in,which the flow of air for combustion is admitted, when'required for combustion by means of the'various parts hereinafter particularly brought out through the medium of damper plate opening and closing member operated by medium of a valve, to sever and renew the communication between the source and the furnace intake when the air for cornbus tion is not required on heating furnaces of steam,
hot water, vapor, or hot air using coal, wood, gas, or oil fuel.
One of the objects of the invention is to provide a device .to prevent cold air fromentering the furnace after an automatic stop, of gas, coal, wood, or oil fired furnaces, and thereby preventing thesurfaces of the interior of the furnace, which is primarily intended as heating surfaces, from being cooled during the stand byperiod, after the desired temperature has been reached, with the resultant saving of fuel of whatever sort used, and
in an even temperature, and to provide the necessary draft for an increased temperature, Another object is to provide a device of fewparts; no complicated movable parts, and of such design and construction as to be easily installed in any type of heating furnace irrespective as to the fuel used. A further object is to provide a device as hereinafter described which will be convenient in operation, inexpensive to manufacture, reliable in use, and of such nature as to enableanyone to operate the said device.
While the foregoing explains the general purpose and objects of the invention, other objects and advantages will appear in the specifications 1 that follow, in which the novel features, construction and arrangement will be brought out, described and claimed.
In the accompanying drawing,'and by reference,
made a part of this specification, and in which corresponding parts are denoted by like designating. numerals, is illustrated one form of the embodiments of the invention capable of carrying the same into practical operation, it being understood that the invention is not necessarily limited ithereto, as various changes in shape, proportions, and general assemblage may be resorted to without departing from the principle of the invention, or sacrificing any of its advantages, in which, Figure 1 is a top view, partly in section;
.1 Figure 2 is a front view. To more fully describe the drawing and to make clear the operation and purposes of the herein described invention, the numeral 3 shows a housing or casing attached to the inlet side of the blower by means of screws or tions in, chamber 3. I yoke of lever 11 is a damper 13 pivotally, mounted factory means. One method illustrated'by 3.
A conduit 4 leading from a supply of 'oil under pressure is connected with casingfi by means of a coupling having a ball check valve 5 pressed to its seat bymeans of'spring 6. It will be obvious by' refere nce to the drawing that the oil pressure in casing 3 is controlled by checkvalve 5 so constructed'that a-slow flow from casing 3 to conduit 4 takes place to relieve the former of the pressure therein when the pressure in conduit 4' drops" Located in'casing 3 is a bellows 8 responsive to. the pressuretherein. A stem 7. passes through casing 3. I he free fendof bellows 8 is connected with the upper end of stem 7 by means of a reduced portion that forms a shoulder. A spring 9 tending to-normal1y expand the bellows surrounding stem 7. IA yoke shaped lever 1 1"is pivoted at 10 on the lower partoi casing 3. The
lower endof stem '1 is providedwith 'cross pin 15 uponwhich lever ll rests intermediate its ends whereby it moves in response to" pressure condi- Between thearms of the the casing,.is supplied by a pump and through the line 4 giving movement to the ball check 5 pressing on the bellows and spring '6 to provide movement to the piston rod or arm "'7 movably connected by a pin 15 to the arm'lO' of the yoke shaped member 11 and through the free movement 7 gives action thereto and thereby causes the tcp'jmostposition and the lower portion to work in unison away from the intake 13 in an angular movement. This movement is controlled by the bolts 14 adjustably secured to permit or cause one portion of the periphery'of the damper plate to stop and the yoke arms continue to swing the opposite portion of the periphery of the damper plate in'a slow angular movement assuming a position parallel with the inlet face of the blower, which regulates the exact draft required by the particular make of the furnace. After the correct amount of draft has been permitted to enter, the automaticshut off causes the yoke shaped member to cause the draft damper plate to again close. -When' the damper plate has been opened the oil pressure, as supplied by the burner pump through the line 4 will be maintained as long as the burner pump operates. When the burner pump has stopped, the pressure willremain for some time in the housing, held there by the ball check which will permit the air of combustion to enter the fire pot fora period of time after the burner has stopped. Thiswill permit the combustion of all fuel. As the oil slowly leaks past the ball check valve, in which the seat has been scored-the spring will cause the piston v to pull on pin attached lever, with the damper plate attached as described, against the inlet port of the blower, thus preventing continuous inlet of cold air over the heating surface of the furnace, and efiecting a savingt :of-fuel b'y retaining the heat in the furnace. It is to be understood, that in showingand describing one method, thatI donot confine myself to that particular form, but other methods can be adoptedas in the instant "construction either metal bellows, a metal diaphragm, a fabricidia- 'sure; oil pressure or electrically, or a phragm,-or' a solenoid coil, or an eIectrd-magnet can be used for the motive power; and can be operated on oil burners either with airprestionof the same. I
For a gas fired boiler the use of electricity ispreferred with a solenoidcoil or magnetfbut there may beused a diaphragm operated by gas pressure to open damperwhen starting, and closev the'same by means of a'spring or weight, during" the standby period; :and with the ball check preventing too quiche, closingof the'intake.
damper on the furnace. For mechanicalicoal burners, to prevent the continuous draft after blower has been automatically stopped which would-"cause over heating andfl waste of fuel, I prefer, but do not restrict myselflto the use of the device substantially as shown for operating the inlet damper of the blower using a solenoid coil in parallel or series with the electric circuit to the motor, sothat on the starting of the motor the solenoid coil will pushfopen the air inlet damper and compress the spring, and on the stopping'wiii be dema'gnetized'and the spring willclose the damper at once, thereby co'mbinaw I 2. In combination with a pipe adapted to be damper is retarded.
preventing to a large extent overheating and the consistent saving of fuel by preventing the chimney draft continuing to pull the fire after an automatic shutdown.
