WATER-TUBE BOILER- SPECIFICATION forming part of Letters Patent No. 790,763, dated May 23, 1905.
Application filed February 13, 1905. Serial No. 245,508.
To all mil/07m it 77MLZ/ concern.-
Be it known that I, SOREN THURSTENSEN, a citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Water-Tube Boilers, of which the following is a specification.
This invention relates to the construction and arrangement of the drums and connecting water-tubes of the boiler as a whole, and relates more particularly to the method of forming the drums and connecting them together and to the provision of means for tightly and securely uniting the tubes to the drums.
The invention has for its object to provide smooth flat surfaces for the insertion of the tubes, so that they will project at right angles to the surfaces into which they are inserted, which insures a much firmer joint and at the same time enables the drums to be arranged more evenly and uniformly.
Another object of the invention is to provide means for an easy access to the drums and tubes for the purpose of cleaning or repairing by so positioning the tubes that easy access may be had thereto from the interior of the drums or headers.
The invention further relates to the method of riveting together the plates composing the drums and to the means employed for securing together the drums in pairs; and the invention finally consists in the features of construction and combination of parts hereinafter described and claimed.
In the drawings illustrating the invention, Figure 1 is a longitudinal sectional view of the boiler of the present invention; Fig. 2, a halfsectional view showing in elevation the front of the boiler and a section taken on line 2 2 of Fig. 1; Fig. 3, an enlarged cross-section of a pair of companion drums, showing the tubes inserted thereinto; Fig. 4, a sectional plan view of one of the drums of Fig. 3, and Fig. 5 a longitudinal sectional View through the two drums of Fig. 3.
The boiler as a whole consists of steam and water drums 1, each provided at its rear end with a cap 2 and its forward end with a cap 3, cap 2 being provided with a manhole 4 of the usual type. The steam and water drums are supported by means of hangers 5 or in any other suitable manner. Near the rear end of each steam and Water drum is aheader 6, which outwardly projects from each side of the boiler to form chambers 7, and the un 5 5 der face of the header as a whole is formed to provide a flat attaching-surface 8, through which surface are entered a series of vertical water-tubes 9, arranged in double rows and extending transversely from end to end of the header, as best shown in Fig. 2. The pipes lead to and connect with a mud-drum 10, which mud-drum is connected with a lower drum 11, from which lead three rows of lower tubes, a top row of lower tubes 12, a middle row 13, and a bottom row 14, the top and bottom rows being in vertical alinement with one another and the middle row in staggered relation thereto. The lower series of tubes lead to intermediate lower and upper drums 7o 15 and 16 at the forward end of the boiler, and the upper intermediate drum 16 has leading therefrom a series of top water-tubes 17, middle tubes 18, and bottom tubes 19, the top and bottom rows of tubes being in alinement and the middle row in staggered relation, as
in the case of the lower series of pipes. The intermediate tubes connect with a pair of rear drums 20 and 21, from the latter of which extend upper rows of tubes 22, 23, and 24, ar- 0 ranged in the manner hitherto described with reference to the intermediate and lower rows of tubes. The two upper sets of tubes hitherto described are arranged at a uniform slope of less degree than the lower set, and the up- 8 5 per row terminates in a top header 25, which connects, by means of a neck 26, with the forward end of the steam and water drum 1.
Each of the drums hitherto described is formed to have a receiving-face for the tubes, 9 so constructed that the top, middle, and lower rows of tubes will enter a plain flat surface, and the method of forming the individual drums and of attaching the pairs of drums together is illustrated in detail in Fig. 3, which shows a pair of drums, such as 15 and 16, united together; but it will be understood that the method of forming the attaching-face point.
of the tubes is the same in the single drums as in the double or compound drums. As shown, each of the drums is formed to have a circular cap or head 27, provided with an inwardly-extending circular flange 28, and one or more of the caps may be provided, if desired, with a manhole 29 of the usual character. The drums, which are cylindrical in shape and extend from side to side ofthe boiler, each consist of an attaching-plate 30, which is normally curved in cross-section, and said plate at its center 31 substantially retains its normal shape or curvature and provides an attaching surface for the middle rows of tubes, which are so arranged that they extend at substantially right angles to the surface of the drum at this point. This attaching-surface 31 forms an intermediate ridge, and the normally rounded surface of the plate is inwardly depressed above and below the ridge at the points 32 and 33 and outwardly bulged at the points 34 and 35, which leaves a series of pockets 36 and 37 in transverse alinement with one another and at suitable intervals to receive the upper and lower tubes, and each of the pockets presents a flat attaching-surface at the proper angle to have the top and bottom rows of Water-tubes inserted at right angles thereinto. The plates at their ends 38 retain their normal curvature and are adapted to be secured around the flanges of the caps or heads of the drums by means of rivets or other attaching means.
The method of forming the attaching-faces hitherto described applies to all of the drums, since it is immaterial in forming the attaching-face whether the drums be formed singly or in pairs; but, as hitherto explained, several of the drums are formed in pairs and secured together in the following manner: The ad joining edges 39 of the attaching-plates are inwardly projected to form flanges, between which flanges is inserted a flat plate 40, which extends entirely across the floor of the upper drum and roof of the lower drum, and the drums are completed by means of curved outer plates 41 and curved connecting-plates 42, which latter are secured to the outer edges 43 of the attaching-plates and serve to complete the drums as a whole. The inwardly-extendingadjoining edges 44 of the outer plates 41 are in alinement with the adjoining edges 39 of the attaching-plates and are likewise secured to the intermediate plate by means of rivets or other attaching means, and the ends of the edges at 45 where the edges are contacted by the flange 28 of the head are tapered down tothe level of the plate 40, so that there may be no appreciable ridge between the plate 40 and the edges secured thereto at this The companion drums are connected by means of holes 46 and 47, which are cut through the connecting-plate 40 and provide for a free circulation of water from one drum drums are inwardly flanged at suitable inter-' vals to form hand-holes 48, which are located opposite to and in alinement with the watertube openings in the attaching-plates, so that a cleaner may be run through the tubes without difliculty.
The steam and water drum has entered thereinto feed-pipe 49 in communication with cross-header 6, and the mud-drum 10 has leading therefrom a blow-off pipe 50, which allows the drum to be flushed and cleaned of sediment or impurities.
The boiler is provided with a grate 51, a bridge-wall 52, lower, intermediate, and upper abutments 53, 54, and 55, and an uptake draft-damper 56, which provide for the passage of the products of combustion along the tubes and insure a thorough utilization of the products of combustion. The present invention, however, relates rather to the method of forming the drums and uniting the tubes thereto than to the formation and arrangement of the boiler as a whole.
The method of forming the headers herein described provides three parallel attachingsurfaces, each disposed at the correct angle to receive a row of water-tubes at right angles, which arrangement obviates the necessity of entering the tubes at an oblique angle to the surface of the drum or of providing elbows or turns'for bringing the tubes into right-angle relation to the point of attachment. The method of forming the attaching-surface provides a separate distinct pocket or receptacle for each of the outer rows of water-tubes and leaves the attaching-surface for the center row at the normal or original curve of the plate, which method of pressing or stamping the plate does not weaken or stretch the metal, since the metal is pressed in on one side and out of its normal curvature on the other side, thereby neutralizing the effect of the pressing and taking up on one side the metal displaced on the other. The method of attaching the companion drums together equalizes the pressure on both sides of the connectingplates, which is practically the only flat surface exposed. At the same time the method of reinforcing the drums at the point of attachment provides a firm and rigid connection and dispenses with the necessity for using short connecting-pipes between the companion drums.
What I regard as new, and desire to secure by Letters Patent, is
1. In a water-tube boiler,companion drums, each having an attaching-surface formed to providea central ridge having adjacent thereto on opposite sides flat attaching-surfaces formed by bending the metal of the drum out of its normal curvature, rows of central water-tubes entered into the central ridges, rows of water-tubes entered into the pockets adjacent to the ridges, and means for securing together the adjoining portions of the two drums, substantially as described.
