Description
May 9, 1950 W. B. VAN WERT BOILER Filed June 24, 1947 I J I ATTD R N EYE Patented May 9, 1950 UNITED STATES PATENT OFFICE BOILER William B. Van Wert, Peckville, Pa.
Application June 24, 1947, Serial No. 756,684
2 Claims.
This invention relates to boilers which are adapted for use in the heating of water for house- .hold heating systems, but is especially adapted that it operates with a high degree of efficiency at a low fuel consumption.
A further object of the invention is to provide a boiler having a primary and secondary water chamber or jacket and wherein return condensation from the steam or vapor heating system returns to the secondary water chamber or jacket to be heated by flue gasses before passing into and mixing with the water in the primary water chamber or jacket, thus preventing the shock or dampening effect so common in present day steam or vapor heating systems.
With the above and other objects and advantages in view, the invention consists of the novel details of construction, arrangement and combination of parts more fully hereinafter described, claimed and illustrated in the accornpanying drawing in which:
Figure 1 is a top plan view of an embodiment of the invention;
Figure 2 is a vertical sectional view on the line 2-2 of Figure 1;
Figure 3 is a transverse sectional view on the line 3-3 of Figure 2 and Figure 4 is a transverse sectional view on the line 44 of Figure 2.
Referring more in detail to the drawing, the boiler l embodying the invention has side walls H and I2 respectively, a front wall I3 and a rear wall [4, which are welded together along their vertical edges to form the boiler H]. A top [5, having a centrally located inlet I 6, is then welded to the upper edges of the walls.
Secured to the inner surface of the rear wall is an inner construction which is similar to the boiler Ill, having side walls I! and I8, a front wall l9, a top 21) and an inset rear wall 2|. The boxlike structure '22 thus formed provides the combustion chamber 23. The lower edges of the walls of the structure 22 are provided with outwardly right angularly extending flanges 24 and the sidewalls, top and front wall form the water 2 chamber or jacket 25, while the rear wall forms the water chamber or jacket 26.
The rear wall has a flue 21 welded at right angles thereto which communicates with the combustion chamber 23 and extends outwardly of the wall 14 through the opening 28 which is sealed by welding the flue thereto. The front wall also has a flue 29 welded at right angles thereto which communicates with the combustion chamber 23, and extends outwardly of the wall [3 through the opening 36 which is sealed by Welding the flue thereto.
The top 20 of the enclosure '22 is provided with short tubes 3! extending upwardly therefrom, which communicate with the chamber 25, and the side walls I! and I8 are provided with three relatively spaced rectangular horizontally inclined water tubes 32 which are welded at their open ends to' the side walls ll and I8, and the tubes communicate with the chamber 25. The tubes 32 are within the combustion chamber 23 and the center tube is supported by a plate 33 welded thereto, and to the inner surface of the t gm,
A substantially U-shaped water tube 34 is welded to the side walls l1 and 18 about the tubes 32, and the tube 34 has a short leg 35, a base 36 and a long leg 31 which extends downwardly to the lower end of the side walls l1 and I8.
The base 36 underlies the tubes 32 and a boxlike structure 38 extends from the side wall I l to the side wall i1 and is provided with a clean out door 39, while a boxlike structure 40 extends from the side wall l2 to the side wall 18, and is provided with a clean out door 4|.
The boiler sets on a frame 42 which is provided with an annular upstanding flange 43 to retain the boiler thereon, and a stoker 44 passes through the frame 42 to provide heating means for the boiler.
A portion 45 is provided in the frame 42, transversely thereof, in alinement with the leg 31 of the tube 34, and the frame, at this side, is provided with a clean out door 46.
The water line in chamber 26 is level with the upper ends of the tubes 3| and this line is constant, maintained by return condensation to chamber 26 from the heating system. The water line in chamber 25 is maintained by means of the manually operated valve 41 or an automatic feeder to compensate for any losses of the water in the chamber 25, through the vent valves in the heating system. The returning condensation from the steam or vapor heating system returning to the chamber 26 through the pipe line 49,
is heated by the flue gasses passing outwardly of the flue 27 before it passes through the tubes 3| to mix with the water in the chamber 25. Thus shock or dampening effect of cool water returning to the chamber 25, which is common in present day steam or vapor heating systems, is prevented. A visible water gauge 48 communicating with the top of the chamber 25 of the boiler I gives a visual check of the water level in the chamber 25. In this manner, the water in the chamber 25 can be replenished as necessary through the valve 41 which permits the water to enter chamber 26 first, and then overflow into the chamber 25 through the pipes 3| until the proper water level is reached.
The boiler is made in sheets which are" welded together along their vertical edges; the tubes are welded to the inner enclosure and the inner enclosure is then welded to the boiler. are then welded as previously described, and the boiler is ready for connection tO'a watersupply.
There has thus been provided a boiler construction made of sheet metal plateswelded at their abutting edges. The heat for the boiler contacts a wide area of the interior construction of the boiler, which houses the water'tobe heated, and the boiler is particularly advantageous in use in heating systems utilizing steam or vapor in transmitting heating energy.
It is believed that the simplicity of the construction of the boiler willbe apparent to those skilled in the art, and it is-to be understood that changes in the minor details of construction, arrangement and combination of parts may be resorted to, provided they fall within the spirit of the invention and the scope of the appended claims.
Having thus described the invention, what is claimed as new and. desired to be" secured by Letters Patent is:
1. A boiler of the character" described, comprising sheet metal wall plates secured together along their vertical abutting edges, 2. top plate secured to the upper edges of said wall plates, at
The fines 4 second set of sheet metal wall plates secured together along their vertical abutting edges and to one of the first mentioned wall plates interiorly thereof to form a combustion chamber and a water jacket or chamber, rectangular horizontally disposed relatively spaced water tubes secured to opposite wall plates of said second set of wall plates, a substantially U-shaped tube secured to the opposite wall plate and enclosing said first tubes, 2. depending tube'formed on the U-shaped tube at one end thereof and extending downwardly to the ends of the side walls all of said tubes communicating with said water jacket or chamber, said tubes forming circuitous passages through which the heat passes for the heating of the water in said tubes and jacket.
2. A boiler of the character described, comprising an outer boxlike structure and an inner boxlike structure, both of said structures being closed at the top, the inner structure being open at. the bottom and the outer structure being closed at the. bottom by an annular flange formed on said inner structure at the lower ends thereof, rectangular horizontally disposed relatively spaced water tubes and a U-shaped water tube enclosing said first water tubes and having a depending portion formed integral therewith extending transversely of the inner structure and all of said water tubes secured to the walls of said inner structure and a frame for supporting said structures above a fire box.
