Application led February 2, 1914. Serial No. 816,117.

To all whom it may concern Be it known that I, G-UsTAvn F. FUcHs, a citizen of the United States, residing at Belleville, in the county of S-t. Clair and State of Illinois, have invented certain new and useful Improvements in Sectional Boilers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in sectional boilers.

One object of the invention is to provide a boiler comp-rising a series of hollow sections which are constructed and arranged to form when properly connected, the maga zine, fire-box and the smoke and gas conducting fiues and combustion chamber of the furnace, said fire-box and flues being arranged to produce the base burning and down draft features which are desirable in this form of boiler.

With this and other objects in view, the invention consists of certain novel features of construction, and the combination and arrangement of parts as will be more fully described and claimed,

In the accompanying drawings: Figurevl is a perspective view of my improved boiler with parts broken away and in section; Fig. 2 is a central longitudinal vertical section of the boiler; Fig. 3 is a vertical cross sectional view taken through one of the sections of the boiler and on the line 3-3 of Fig. Z1; Fig. 1 is a vertical longitudinal section taken on the line 41-4 of Fig. 3; Fig. 5 is a horizontal sectional view takenvon the line 5-5 of Fig. 3; Fig. 6 is a similar view taken on the line 6-6 of Fig. 3; Fig. 7 is a similar view taken on the line 7-7 of Fig. 3; Fig. 8 is a vertical cross section taken between two of the sections of the boiler4 on the line 8-8 of Fig. 2; Fig. 9 is a similar view taken on the line 9--9 of Fig. 2 and looking at the inner side of the rear section of the boiler; Fig. 10 is an inner side view of the front section of the boiler.

My improved boiler comprises a front section 1 and a rear section 2 and a series of intermediate sections 3, 4 and 5 and 6. All of the sections of the boiler are hollow` or are provided with water circulating spaces and said sections are connected or securely fastened together to form the boiler by tie rods or bolts 7 which are suitably arranged chamb er therethrough as shown. The water spaces the top of the sections and at the opposite sides of the bottom thereof are connected by slip joints in the form of nipples 8 which are engaged with thedischarge openings on one side of the sections and with the inlet openings in the adjacent sides of the adj oining sections whereby the water is permitted to circulate freely between the hollow walls of the sections.

The front section 1 of the boiler comprises a front plate 9 having arranged in the center of the upper portion thereof a firing door 10 and in the lower portion thereof a slicing door 11. In the front plate on opposite sides of the iringdoor are formed cleanout openings 12, similar openings 13 being arranged on opposite sides of the lower door 11, while between the upper and lower cleanout doors and in line therewith are arranged intermediate cleanout doors 141. The sides of the section 1 are in the form of hollow water legs 15 which are connected at their upper ends with an arched water chamber 16 which forms the top of the section. Spaced from the hollow sides or water legs 15 of the section 1 are intermediate water legsr 17 which extend from the bottom of the section to a point in line with the bottom of the upper clean out openings 12 in the front plate of the section. At their lower ends the water legs 17 are connected with the lower ends of the hollow sides or outer water legs of the sections by short hollow connections 18 and at their upper ends said water legs are connected with the hollow sides or outer water legs 15 by similar hollow connections 19, said connections 19, however being only approximately half the width of the water legs 15 and 17, thus forming a `space or opening 20 between this part of the section 1 and the adjacent part of the adjoining section 2. Connected at their upper end to the inner sides of the 16 forming the top of the section and extending downwardly therefrom parallel to the intermediate water legs 17 are inner. water legs 21. The water legs 21 are spaced a short distance from the water legs 17 and terminate at their lower ends in line with the top of the space forming the reboX hereinafter described.

The section 2 of the boiler comprises hollow sides which form outer water legs 22 and which are connected at their upper ends by a hollow arched water chamber 23.

Spaced a suitable distance from the'wat'er' legs 22 formed by the sides of this section lare intermediate water legs 24. rlhe legs 24 are connected at their lower ends to the lower ends of the outer water legs 22 by hollow connections 25 and said water legs 24 terminate at their upper ends in line with the upper ends of the intermediate water legs 17 o-f the section l. At their upper ends the water legs 24 are connected withl the outer water legs of the section by trans-A verse hollow water circulating connectionsE 26, which are of less width than the ,watery legs 24, thus forming on one side the continuous spaces 27. Midway between the upper and lower ends of the water legs 24 the; latter are connected with the outer water; legs by hollow connections 28, said connec-' tions being of less width than the water; legs and being disposed below the spaces 27 formed by the connections at the upper endsl of the water legs.l Connected at their upper ends with the water chamber 23 and eXtending downwardly parallel with the intermediate water legs 24 and spaced a suitable distance therefrom are inner Water legs 29 the lower ends of which terminate in line with.E the top of the hre-box or with the lowerl ends of the inner water legs 2l of the section l. The lower ends of the water'legs 29 aref` connected to the adjacent portion of theg; intermediate legs 24 by hollow connectionsi 30 on each side of which and between thei same and the corresponding connections ofthe adjoining 'sections are formed drafty openings 3l which will be hereinafter de scribed.

The section 4 of the boiler comprises hollow .sides which form outer legs 32 and which are connected at their upper ends to an arched water chamber 33. Spaced from the sides or water legs 32 are intermediate llegs 34 which are connected at their lower ends to the lower ends of the outer water legs by hollow connections 35 and at their upper ends are connected to the outer water legs by hollow connections 36, said connections being of Aless width .than the water legs and disposed in positions between the j oppositeedges of the legs as shown. Between the opposite sides of the connections 36 when thus arranged and similar connec# -tions on the adjoining sections of the boiler are formed openings 37 which provide for the circulation of the products of combustion through the passages formed between the water legs as will be hereinafter described. The water legs 34 are also connected with the outer water legs 32 by hollow connections 38 corresponding to the connections 28 of the section 3 except that the connections 38 extend entirely across the space between the inner and outer water legs as shown. Extending downwardly from and connected at their upper ends with the chamber 33 are inner water-legs 39 which are connected at their lower ends with the intermediate water legs 34 by narrow centrally disposed hollow connections 40. `The water legs 39 are also connected with the upper ends of the water legs 34 by narrow hollow connections 4l which are arranged in line with the lower connections 40.

The section 5 of the boiler is constructed in exactly the same manner as the section 4 except that the inner water legs 42 of this section are connected by a hollow wall 43 which extends from the top of the fire box upwardly to and is connected at its upper end with the arched water chamber of the section 5. The wall 43 forms the back of the magazine above the fire-box of the boiler, the front of the magazine and fireboX being formed by the front The section 6 of the boiler comprises hollow sides which form outer water legs 45 and which connect at their upper ends with plate of the section l hereinbefore described.

the arched water 'chamber'46of this section.

Spaced from the water legs 45 and,` extending upwardly in parallel relation thereto are inner water legs.. 47 which connectat their lower ends with the lower ends of the outer water legs by hollow connections 48 and said inner water legs 47 are further connected with the outer vwater legs above the connections 48 by hollow connections 49 corresponding to the similarly arranged connections in the sections 4 and 5. The water legs 47 terminate at their upper ends in line with the intermediate water legs ofthe previously described section and said water legs 47 are connected at their rear edges by a hollow vertical wall 50 from the bottom to the top of the boiler and is connected at its upper end with the water chamber 46. In the upper portion of the hollow vwall 50 immediately below the water .which extends ioschamber 46 and adjacent to the side edges i of the wall are discharge openings 5l which form an outlet for the products of combustionl passing from the space 52 which is formed between the wall 43 of the section 5 and the wall 50 of the section 6 and which communicates at its lower end. with the space forming the fire-box, and through whichthe smoke and gases are drawn from the latter.

The rear section 2 of the boiler comprises hollow sides 53 which form outer water legs and. which are connected at'their upper ends to a hollow arched chamber 54 forming the top of this section. The water legs 53 are connected at their lower ends by a hollow connection 55 which extends entirely across from one lside to the other of the section and forms the bottom thereof. The sides 53 are further connected above the bottom connection and in line withl the intermediate connections of the previously described sections by a hollow transverse partition 56 which separates the Arear section into an upper combustion chamber 57 and a lower smoke box or chamber 58. rlhe hollow sides, top, bottom and partition of the section 2 are connected at their rear edges with a hollow wall 59 which forms the rear end of the boiler. In the lower portion of the wall 59 and opening into the center of the smoke chamber 58 is a smoke discharge opening 60 which is adapted to be connected with a stack (not shown). In the wall 59 immediately above the partition 56 and near the opposite sides of the combustion chamber 57 are clean out openings 61 which in practice are closed by suitable doors.

By constructing the various sections of the boiler as herein shown and described it will be seen that when said sections are assembled the spaces formed between the outer sides or water legs and the intermediate water legs of the sections and between the transverse hollow connections of said legs will form upper and lower continuous fiues 62 and 63 which are connected at the front end of the boiler through the opening between the front edge of the hollow connection 28 of the section 3 and the front wall of the boiler. rlhe upper iues 62 in the opposite sides of the boiler communicate at their rear ends with the combustion chamber 57 in the rear section of the boiler, while the rear ends of the lower flues 63 connect with the smoke chamber 53 in said rear section.

The spaces between the inner and intermediate water legs of the sections form draft iues 64 the forward ends ofwhich are closed by the front wall of the boiler and the rear ends of which communicate with the draft passage between back wall 43 of the magazine and the wall 50 of the section 6. The draft flues 64 communicate at their lowerends with the space forming the fire-box, through the openings formed between the various hollow connections which connect the lower ends of the inner water legs with the intermediate water legs of the sections. The flues 64 are connected at their upper ends, through the openings between the upper hollow connections of the inner and intermediate water legs, with upper draft flues 65 arranged above the flues 62 and communicating therewith through the openings between the upper hollow connections which connect the outer and intermediate water legs of the sections.

The course of the products of combustion through the various flues of the boiler is shown by arrows in Fig. l of the drawings and may be described as follows: The smoke and gases when leaving the fire-boX pass upwardly through the space or passage between the walls 43 and 50 and pass through the openings 5l into the combustion chamber where further combustion takes place. rlhe products of combustion from the combustion chamber pass forwardly through the upper flues 62 to the forward end of the boiler, thence into the lower iiues 63 and back through said lower flues into the smoke chamber 53 from whence the products of combustion pass into a suitable stack. In addition to this circulation of the products of combustion a certain amount of the latter will pass upwardly through the side draft flues 64 between the inner and intermediate water legs of the sections and into the upper draft flues 65 from whence these products are discharged into the flues 62 and commingle with the products passing through the latter.

Water discharging connections 66 are arranged in the upper portion of the boiler, two of said connections being preferably provided, one of which is arranged in and connects with the water chamber of the section 3 and the other of which is arranged in and connects with the water chamber of the section 5. Return water connections 67 are also provided on opposite sides of the boiler, said connections being preferably disposed on the outer sides of the lower ends of the side walls or outer water legs of the sections 3 and 5 as shown. It will be noted that the lower ends of the side walls or outer legs of the sections are increased in width or extend outwardly beyond the outer sides of the sections as shown. By arranging the water legs or hollow walls of the sections as herein shown and described it will be seen that a large heating surface is provided, thus causing the water in the boiler to be quickly heated as it circulates through said hollow walls and the upper water chambers of the sections.

The sections of the boiler when constructed and connected in the manner described are supported upon a hollow base 63 in the upper portion of which is arranged a grate 69 which forms the bottom of the fire-box and which provides beneath said grate an ash-pit through which the ashes may be removed through a suitable door 70 arranged in the end of the base as shown. The front end of the base extends upwardly at the central portion thereof and has arranged therein a door 71 which closes the opening l1 in the front end of the boiler. It will be noted that when the various sections of the boiler are assembled that the clean out openings: in the front wall of the front section of the boiler are in line with the various fines of the boiler and thus permit said iues to be readily cleaned when necessary.

From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.
