METHQD OF HEATING.
Original application filed June 28, 1916, Serial Ito. 105,526. Divided and this application 1916. Serial No. uaaaa To all whom it may concern:
Be it known that we, WILLIAM WALLACE KEMP and WILLIAM H- VAN HORN, citizens of the United States, residin at Baltimore, in the county of Baltimore ity and State of Maryland, have invented new and useful Improvements in Methods of Heating, of which the following is a specificatmn.
This invention relates to heaters, and more particularly to the method of heatmg carried out therein, and has as its ob ect to provide a method of heating WhBI'GlIl. a blast flame is utilized to create and maintain the circulation of a heated gaseous medium through a passage, the heated medium being repeatedly returned to the flame or blast to be heated thereby.-
By returning the gaseous medium or products of combustion 'to the flame and repeatedly heating them in accordance with our improved method, a reat econom 1n the consumption of .fuel 1s obtained, or after passing through the passage, the combustion products still possess cons1derable heat, and less fuel is requiredto heat them to the desired temperature than if fresh atmosphenc air were used. The heated gases or products of combustion are caused to circulate rapidly through the device employed in carrying out our improved method, the heat distribution is uniform, and the temperature produced may be easily and perfectly controlled, while, at the same time, the discharge of the products of combustion and dust into a chamber which it may 'be desired to heat is avoided.
lhis ap lication is a division of our application or Letters Patent filedthe twentythird day of June, 1916, Serial No. 105,526.
In the accompanying drawings, we have.
illustrated an apparatus suitable for carrying the invention into practical use, and a description of our method of heating and utilizing the illustrated apparatus which will be sufiiciently descriptive of such process when other apparatus is employed for carrying the-same into use.
in said drawinge,--
Figure 1 is elevaticnal view of the apparatus, a portion of the heater being broken away to discl se the banner.
Fig. 9. is a view similar to Fig. 1, showing a slightly diil-erent construction.
Referring to the drawings, wherein like numerals represent like parts in the several views, We have shown, in thepr'esent in- Specification of Letters Patent.

stance, our improved method of heating as carried out in a heater com risin a radiator, but, of course, the method 0 heating herein described ma be utilized in apparatus other than radiators. 10 designates a radiating pipe which is endless in that it forms a continuous passa e through which the heated products of comliustion are adapted to circulate. The radiating pipe may be of any suitable construction, and may be constructed of wrought iron or any other suitable material.
Mounted within the radiating pipe is a burner tube 11 retained centrally within the ipe by means of brackets or spiders 12. The
urner-tube 11 is mounted preferably at one of the angles or elbows of the radiating pipe with its inner ,end extending longitudinally into the inlet portion 13 of the radiating pipe and its outer end projecting into the elbow, the latter end being in alinement with the through opening in the return portion 14 01' the radiating pipe. Extending through an openin 15 in the wall of the radiating pipe, an in alinement with the tube 11 is a gas pipe 16 carrying on its inner end a burner 17 which may be of any suitable construction. The pipe 16 leads from a suitable air and gas mixing device, and while any such suitable device may be employed, we prefer to connect the pipe 16 too. gas and air mixing apparatus ofthe general type disclosed in Patent No. 1,141,466, dated June 1, 1915, granted to W. H. Van Horn and Wm. W. Kemp. In the device described in the last- Inentioned patent, air and as are mixed in such proportions, that t e mixture is flame-sustaining; .that is, sufficient oxygen is in the mixture to completely burn the gas mixed-therewith and no outside'supporter of combustion is required. The pipe 16 has a regulatin and shut-oil cook 17' which may be of any esired form, and which has an operating handle 18 provided with a pointer 19 which is adapted to move over an indicating scale upon the plate or member 20 when the handle is turned.
In Fig. 2, we have shown a device similar shown the same applied in Fig. 2 to a 'apanning oven by way of illustration only.
11 such oven, itis particularly desirable to eliminate introduction of products of combustion or dust into the space in which the articles to be japanned are located, to obtain a relatively high heat and to heat the oven uniformly and with the use of our device, these requisites are obtained.
In Fig. 2, the radiator is shown as pro-- 'vided with a neck portion 22 extending through an opening in the wall of the japan: ning oven and having a chamber 23 with which the ends of the radiating pipes 10 are in communication, and by this construction, the exhaust gases may be discharged through the opening 15 about the pipe 16 into theatmosphere and thus introduction of these exhaust gases into the oven is eliminated. The tube 11 is so mounted that its outlet end lies within the inlet portion 13 of the radiating ipe and its inlet end lies within the cham-.
When it is desired to place the device disclosed in the drawings in operation, the handle 18 is turned (the amount to. which it is turned being indicated by the position of .the pointer over the scale), to admit the air and gas mixture from its source (not shown) to the burner where it is ignited. The mixture of air and gas produces a flame which is self-sustaining, and the mixture is projected into the tube 11 with considerable pressure, thereby causing the products of combustion to travel through the tube 11 with considerable velocity. A strong suction is thus created about the burner which draws or entrains atmospheric air into the tube 11 and about the burner. The products of combustion together with the entrained air are discharged from the outlet end of the tube 11 into the pipe 10 and the same circulate through the'pipe 10 with considerable rapidity.
Immediately after starting the burner, an influx of air through the opening 15 is noticeable, and then for a short period of time a noticeable exit of air through the opening 15 may be observed, this exit of air being due to the fact that the products of combustion from the burner forces or scavenges the pipe of the. air with which the same is filled when not in operation. After the device is in operation a short time, the products of combustion are repeatedly circulated through the radiating pipe, a portion of the products of combustion after passing through the return portion 14 of pipe 10 being entrained or drawn into the pipe 11 about the burner 17 and a secondary suction being created in the space between the tube 11 and the surrounding wall of the radiating pipe 10 due to the blast discharge usages} tinuously admitted into the heater through the burner 17 It will be noted that during the normal operation of the device, air or other gas is not admitted to the radiator except through. the burner 17, the gaseous mixture admitted to the burner being in such proportion that the flame is self-supporting. The discharge of combustion products from the burner is such as to force the gaseous medium Within the pipe 10 before them, and, at the same time, a suction action is created about the burner and about the tube 11 ,which draws the gaseous products of combustion passing through the return portion 14 into the inlet portion 13 of the radiator.
These gases are again and again circulated through the radiating pipe and the circulation throughout the entire length of the radiating pipe is very rapid, so that the heat is uniformly distributed. In place of discharging the products of combustion from the pipe after completing the circuit and drawing in fresh air, the products of combustion are again heated by the hot blast from the burner and as the combustion prod .ucts retain some of their heat, it requires less fuel to heat them to any given degree than if outside air were utilized.
When a radiator, in which our method of heating is employed, is applied to a japanning or'other oven, the neck portion 22 preferably extends through an opening in the wall of the oven, so that excess products of combustion discharged from the radiator pass off into the atmosphere and none of the products of combustion enter into the compartment in which the articles are treated, and thus dust and the like due to the burning of fuel, or dust which might be introduced due to draft currents, or stirred up thereby, are entirely eliminated. It is, of course, obvious that the neck portion 22 may be extended to any desired distance outside of the oven 21 so that the burner 17 is sufficiently removed from the oven and this feature is particularly desirable from the fire insurance standpo nt.
Our invention is susceptible of various modifications and changes which would be within the spirit of the invention without departing from the scope of the following claims.
What is claimed is:
1. The method of heating herein described, which consists in discharging at relatively high pressure an ignited flamesustaining mixture into an endless passage from which air is excluded, entraining the products of combustion, causing the circulation thereof within said passage at relatively high velocity, repeatedly heating said products of combustion, and discharging the products of combustion from said passage.
