G. A. CLOSE BOILER June 3, 1947.
Filed Aug. 6, 1945 INVENTOR.
Patented June 3, 1947 UNITED STATES PATENT OFFICE George A. Close, Bay City, Mich.
Application August 6, 1945, Serial No. 609,063
1 Claim.
This invention relates to boilers of the type used in homes, manufacturing plants, and buildings in general where a heating unit is required.
One of the prime objects of the invention is to design a boiler formed of plate sections, welded together so that all parts can be readily assembled and are readily accessible for removal or repair.
Another object is to design a boiler which will be highly efficient in operation, economical to manufacture and assemble, and which is very compact, requiring a minimum floor space for installation.
A still further object is to provide a boiler in which the flame from the burner is disposed directly below the centrally disposed conical shaped water vessel, thus utilizing the full heating potency of the burner,
A still further object is to design a boiler in which the hot gases follow a tortuous path through the boiler so that all heat units are fully utilized.
To the accomplishment of the foregoing and related ends, said invention then consists in the means hereinafter fully described, and particularly pointed out in the claim and annexed drawing, the following description setting forth in detail certain means and one mode of carrying out the invention, such disclosed means and mode illustrating, however, but one of various ways in which the principle of the invention may be used.
In the drawing:
Fig. 1 is a side-elevational view of my improved boiler.
Fig. 2 is a vertical, sectional-elevational view taken on the line 2-2 of Fig. 1.
Fig. 3 is a sectional plan view taken on the line 3--3 of Fig. 1.
Fig. 4 is also a sectional, side-elevational View taken on the line 4-4 of Fig. 3.
In the accompanying drawing in which is shown the preferred embodiment of my invention, the numeral 8 indicates the foundation on which the spaced-apart walls 9 and II] of a sheet metal boiler are mounted as usual, the spacing of the walls forming a water chamber II therebetween, and into which water is introduced by means of a water supply pipe I2 which can be connected to any convenient source of supply.
A centrally disposed, conical shaped vessel V forms a part of the boiler, and is formed as clearly shown in Figs. 1, 2, and 4, the lower end being conical shaped as at I 3, thence tapering upwardly into a cylindrical section I4 and opening into the steam chamber of the boiler, as will be hereinafter described. The lower end of the vessel V is closed by the conical bottom I3.
Pipe lines I5 connect the lower portion of the vessel V with the water chamber II so that full circulation is provided, and a horizontally disposed crown sheet I6 connects the walls I0.
Spaced apart tube sheets I! and IB are provided above the crown sheet I6 and a centrally disposed passage I9 is provided in the crown sheet IE to accommodate the neck I4 of the water vessel, which opens to the steam chamber S in the top of the boiler. The passage I9 is of larger diameter than the neck I4 and the hot gases flow upwardl around the neck I4 and into the passage .20 formed by the tube sheets I1 and +8 and sheets 23.
A plurality of vertically disposed, relatively large tubes 2| are provided in the passage 20 between the tube sheets and through which the water circulates into the top of the boiler, said boiler being provided with a, dome 22 as usual, to which a steam line (not shown) can be connected in the conventional manner.
Vertically disposed sheets 23 and 24 are provided between the tube sheets I! and I8 and form relatively narrow water passages 25, the sheets 24, together with the side wall 9, forming passages 20' between the tube sheets I1 and It in which a plurality of vertically disposed tubes 26 is provided, the center passage 20 leading rearwardly and opening into the passages 21 at the front end of the boiler. The passages 21 communicate with the passage 20' which are connected together as shown to provide a breeching 28 that leads to a stack (not shown).
The gas burner B is located in the combustion chamber 2-9 and is supported on legs 30 as usual, a pipe line 3| leading to any suitable source of supply.
In practice, the flame from the burner B is disposed directly beneath the water vessel V, and the hot gases circulate in the combustion chamber 29 as indicated by the arrows; thence flowing upwardly through the passage I9, thence into the smoke passages 20 around the tubes 26, and thence to the breeching and smoke stack.
A clean-out door 32 is provided in the outer shell and is secured in position by means of bolts 33 as usual. The safety valve and water glass are omitted as they form no part of the present invention.
From the foregoing description, it will be obvious that I have perfected a very simple and efficient all-welded boiler which is easy to assemble and fabricate, and which can be readily cleaned and/or repaired as occasion demands.
What I claim is:
A heating boiler of the class described comprising, inner and outer shells forming a water chamber therebetween, with the inner shell curved inwardly to form a crown sheet, vertically spaced tube sheets above the crown sheet, vertical water tubes between the tube sheets, par- 7 4 titions between the said tube sheets to form horizontally disposed smoke passages therebetween, a centrally disposed smoke flue projecting from said crown sheet and opening into the central passage, a centrally disposed, substantially pearshaped water vessel suspended from the upper tube sheet and passing through the said smoke flue, and vertical tubes between said tube sheets.
