AIR-HEATING DEVICE FOR STOVES.
Specification of Letters Patent.
Patented May 28,1912.
Application filed April 1, 1911. .Serial No. 618,311.
To all whom it may concern Be it known that I, GERRIT VoN DAAM, a citizen of the United States, residing at Scranton, in the county of Lackawanna and State of Pennsylvania, have invented new and useful Improvements in Air-Heating Devices for Stoves, of which the following is a specification.
This invention relates to air heating devices for stoves or furnaces, the object of the invention being to provide a device of this character which can be applied or attached to any well known form of stove or furnace without changing the construction of the same, the device being designed to supply air from the outside to the fire-pot and being positioned so that the air while being conveyed to the fire-pot will be heated so that the air when discharged into the fire-pot may be thoroughly mixed with the unconsumed gases and thereby promote proper combustion.
In the drawings, forming a portion of this specification and in which like numerals of reference indicate similar parts in theseveral views :--Figure 1 is a plan view of a range showing my improved air heating device applied thereto. Fig. 2 is a plan view of the device removed from the range. Fig. 3 is a section online 33 of Fig.' 1. Fig. 4 is a section on line M of Fig. 2. Fig. 5 is a plan view of a slightly modified form of my invention. Fig. 6 is a modified form of the device illustrated in Fig. 1 showing my invention applied to a stove having a single fire-pot.
In the preferred embodiment of my invention I provide an air heating and feed ing device which includes a tube 1 of coil form which is provided intermediate of its ends with a plurality of loops 2. In this form of my invention the device is used in connection with a stove A having a pair of fire-pots B. The tube 1 has one of its terminals attached to a conveying tube 3 disposed below the plane of the tube 1 and waving oppositely extending portions which extend in the direction of the opposite firepots 13, each of such portions having a nozzle or jet head 4 which. latter is bent in wardly intermediate its ends and in advance of the conveying tube 3, as at i, to provide a deflector, the deflector serving to distribute the air evenly throughout the jet heads i, which are perforated, at 5. The perforated side of each head is positioned with respect .to the corresponding fire-pot so that the air can be discharged directly thereinto and across the path of the rising gases. The opposite terminal of the tube is provided with a vertical branch portion 6 which is preferably exteriorly threaded, at
7, to receive a short sleeve 8. This sleeve extends through an opening 9 in the stove lid 10, the outer end of the sleeve having openings 11 therein which may be covered or uncovered by the damper 12, shown in Fig. 3 of the drawings.
The tube 1 has portions extended into grooves or concavities 13 on the inner sur face of the supporting legs 14. These legs depend from the tube and are designed to rest on the wall 15 of the stove, the said wall in this instance forming a part of the discharge conduit C for the smoke and gases, the said conduit being in communication with the pipe 16 as usual. lVith a View of retarding the discharge of the gaseous products from the stove and for allowing a perfect mixture of the air with the unconsumed gases the pipe 16 is provided with a controlling damper 17. The legs 1a are provided with registering or ahning grooves 18 in which a clamping band 19 is fitted and secured, at 20, to the legs. This construction is such that when the clamping band is engaged with the legs as described, the legs will be securely confined in embracing engagement with the tube 1. The tube 1 is horizontally disposed and at' the will of the operator the damper 11 may be controlled manually so as to permit any re quired admission of air from theoutside to the tube. The disposition of the tube in the channel or conduit C is such that the tube will be fully exposed to the heat and in consequence thereof the air as it is spread through the tube will be heated thoroughly before it is discharged into the fire-pot.
In the form of my invention shown in Fig. 5, the tube 1 is in the form of a serpentine coil, one branch or terminal thereof being extended outwardly, at 21, below the plane of the tube 1 and provided with a head 22 which is formed with oppositely extending discharge portions 23, perforated, at 24. The opposite terminal 25 of this tube is adapted to be extended through the stove lid as described in the preferred form of my invention.
In the construction shown in Fi 6, I have illustrated the device applie to a stove having a single fire pot and for this purpose the device is provided with only one nozzle or jet'head. In other respects this form of my invention is identical to 5 that shown in Fig. 1 already described, and therefore a further description of this figure is not deemed necessary.
The discharge end of the air heating and feeding tube shown in Fig. l of the drawingsis located above the plane of the me pot and adjacent to one side thereof and adjacent to the back of the fire-pot so as to re tard the movement of the rising gases at the effective discharge end of the fire-pot.
In the construction shown in Fig. 6, I have shown the device applied to a stove having a single fire-pot and for this purpose it is provided with only one nozzle or jet head. In other respects this form of my invention is identical to that shown in Fig.1 and already described, and therefore, a further description of thisfigure is not deemed necessary.
I claim 1. In an air heating and feeding device for stoves, a fire pot, a tube located above the plane of the fire pot and adjacent therei to and having an intake end and a discharge end located above the plane of the fire pot and adjacent one side thereof, supporting feet for the tube, and a band extending around the feet and operating to hold the 7 feet in embracing engagement with the tube. 2. An air heating and feeding device of the character described comprising a fire pot, a tube located above the plane of the fire pot and adjacent thereto and having an air intake portion and an air discharge portion located above the plane of the fire pot and adjacent one side thereof, grooved feet having their grooved port-ions fitted to the tube, and a band extending around the feet and connecting them with each other and operating to hold the feet operatively associated with the tube.
3. In an air heating and feeding device for stoves, a stove including a fire pot therefor, a coiled tube located above the plane of the fire pot at one side thereof and in the path of the products of combustion and provided at one end with an air intake portion, the opposite end of said tube terminating in a straight conveying tube located in a plane below the plane of the coil, the said conveying tube terminating in jet heads projecting laterally therefrom and located above the plane of the fire pot and adjacent one side thereof so that the air may be directed into the fire pot and across the path of the rising gaseous products.
4. In an air heating and feeding device for stoves, a stove including a fire pot therefor, a coiled tube located above the plane of the fire pot at one side thereof and in the path of the products of combustion and provided atone end with an air intake portion,
