Application March 29, 1937, ‘ Serial ‘No. 133,692 (Cl. 122-318) :2 ..Claims. This invention ,relates to ,Steam ‘boilers and has for the primary‘object the provision ,of a device: of-rthe ‘uprighttype which will be economi cal to construct and operate with various kinds of 5 fuel and has an improved arrangement of tubes each so constructed as to assure maximum ef grate bars '22 are ‘formed. The grate supporting‘ :membrersw2l are spaced from the cylindrical wall ‘I9 to ‘form 1therebetweenand. with the base seats for the 'lower ends of water tubes'23. The ‘tubes 23 are grouped in annular formation, as shown in Figure 4, and annular groups of water tubes ficiency of steam generation. 24 are connected with the head I3 and depend With these and other objects in view, this in vention consists in certain novel features of con downwardly in the ?rebox and are of a shorter 10 struction, combination and arrangement of parts to be hereinafter more fully described and claimed For a complete understanding of my inven tion, reference is to be had to the following de 15 scription and accompanying drawings, in which Figure 1 is a vertical sectional view illustrat ing a steam boiler constructed in accordance with my invention. Figure 2 is a side elevation partly in section 20 illustrating the same. Figure 3 is a sectional view taken on the line 3-—3 of Figure 1. a Figure 4 is a sectional View taken on the line 4-4 of Figure 1. Figure 5 is a vertical sectional view illustrat 25 ing one of the boiler tubes. Figure 6 is an end view illustrating the same. Referring in detail to the drawings, the numer~ al I indicates a boiler, 2 the ?rebox therefor 30 supported by a base 3 in which is located the usual ashpit 4, access thereto being through a doorway normally closed by a hinged door" 5. The boiler I is adapted to be partially ?lled with water and has a water gage 6, drip valve 1, a pressure gage B and a safety valve 9. A water supply pipe is connected with the boiler and is indicated by the character III and a steam outlet pipe is indicated by the character I I. The boiler I includes upper and lower heads I2 and 4:0 I3, the upper head being substantially dome shaped. The heads are joined together by tie rods I4 and are provided with aligned openings length than the water tubes 23 so that the ?re within the ?rebox will be located under the lower ends of the water tubes 24. A door frame for the ?rebox is indicated by the character 25 and is detachably secured to pairs of the tubes 23, as shown at 26. The door frame is equipped with a ?re door 21. The lower ends of the tubes 24 15 terminate above the ?re door. The water tubes 23 and 24 each include a reduced screw threaded upper end threaded in an opening provided in the head I3, as shown at 28. Each water tube 24 and 23 consists of the outer sleeve and an inner tube 29 which extends through the re— duced end 28 into the water of the boiler and is of a diameter less than the internal diameter of the outer sleeve and the reduced end 28 thereof. Pins 30 extend through the tubes 29 and engage the reduced ends 28 of the outer sleeve for suspending the tubes 29 within the outer sleeves, they terminating short of the lower end of the outer sleeve, as shown in Figure 5. The tubes 29 admit water to the outer sleeves where 30 said water is heated and generates into steam and passes therefrom back to the boiler to ac cumulate in the upper portion or steam dome of said boiler. A booster 32 is arranged centrally of the fire box and smoke passage and is connected with the boiler and consists of a head 33 having a chamber 34 therein and connected with said head 33 and depending therefrom are water tubes 35 similar in construction to the water tubes 23 provided with Vertically arranged ?anges detach and 24, except they are shorter in length. A pipe 36 is connected to the head 33 and with the boiler by being threaded in an opening pro vided in the sleeve I5. A tube 3'8 extends from the chamber 34 to the boiler through the pipe 36 for feeding water from the boiler to the chamber 34 and thence to the water tubes 35. The steam from the water tubes 35 returns to the boiler by way of the pipe 36. Due to the mounting of the tubes as shown and described ably secured by bolts or like fasteners 20. in this boiler it is an easy matter to remove any in which is mounted a sleeve I5 acting as a smoke passage. The ends of the sleeve are welded or otherwise secured to the‘heads I2 and I3. A cylindrical wall I6 is riveted or otherwise secured to marginal ?anges formed on the heads I2 and i3 and is provided with a hand opening I‘! nor mally closed by a removable cover IS. The ?rebox 2 includes a cylindrical wall I9 The cylindrical wall I9 is secured to the marginal ?ange of the head I3 and to the base 3. Said 55 base has grate supporting members 2I on which _ one of the tubes when damaged and to sub stitute another therefor and [also due to the particular arrangement of the tubes 2. maximum 55 2 2,126,619 amount of steam may be generated by this boiler with a minimum consumption of fuel. What is claimed is: 1. An upright boiler comprising a ?rebox, a base for said ?rebox, a combined water and steam chamber mounted on said ?rebox and having a smoke passage therethroug‘h, tubes connected to said combined water and steam chamber and depending downwardly in the ?re 10 box and arranged in groups of annular forma tion with certain of said groups supported by the base and the other groups terminating short of the base, each of said tubes including an outer sleeve and an inner tube terminating short of 15 the lower end of the outer sleeve and extending into the combined water and steam chamber, a booster arranged in the ?rebox and connected to the combined water and steam'chamber and including a head having a chamber'with ‘water ' 20 tubes connected thereto and depending from the head. 2. An upright boiler comprising upper and lower heads, tie rods connecting said heads, an annular vwall secured on said vheads and cooper ating therewith in forming a combined water and steam ‘chamber, a sleeve extending through said heads and connected thereto to form a smoke passage, Ia cylindrical wall connected to the lower head, a base supporting the second cylindrical wall and cooperating therewith in forming a ?rebox with an ash pit thereunder, water tubes connected to the lower head and depending down wardly in the ?rebox and certain of said tubes supported by the case, each tube including an outer sleeve and an inner tube, means for sup porting the inner tube within the outer sleeve with the lower end of the inner tube terminat ing short of the lower end of the outer sleeve, a pipe connected. to the combined water and steam chamber and extending into the ?rebox, a head secured to said pipe and having a cham~ ber, a tube extending through the pipe from the chamber of the head to the combined water and steam chamber, and water tubes connected to and depending from said head.
