SPECIFICATION forming part of Letters Patent No. 582,939, dated May 18, 1897.
Application filed November 18, 1896- Serial No. 612,635. (No model.)
following is a specification.
The object of my invention is to improve the construction of sectional water-tube boilers so that they can be used at high pressures.
A further object of the invention is to so form the headers that they can be secured together independently of the nipples and tubes; and my invention further relates to details of construction as full y described hereinafter;
In the accompanying drawings, Figure 1 is a longitudinal sectional view of the front half of my improved steam-boiler. is a longitudinal sectional view of the rear half of the boiler. Fig. 2 is a transverse section on the line 2 2, Fig. 1 Fig. 3 is atrans- Fig. 45 is an enlarged sectional View through the front header. Fig. 5 is a sectional plan view on the line 5 5, Fig. 4. Fig. 6 is a sectional View on the line 6 6, Fig. 4:. Fig. 7 is a perspective View of one of the header-sections. Fig. 8 is a perspective View of one of the caps. Figs. 9 and 10 are views showing the method of making the joints between the header and tubes, and Fig. 11 is a section on the line 11 11, Fig. 2, of one of the drumheaders.
A are the walls of the boiler, in the present instance of brick. On the side walls a rest the shoes 0 of the plates 0, which carry the drums B, six in the present instance, arranged in two rows, one above the other.
On the front wall a rests the front header D, and on the Wall a rests the rear header D.
Fig. 1
These heads are connected by inclined heatthis wall is another plate f, to direct the products of combustion downward before entering the chimney-flue f.
Each of the drums B is connected to drumheaders B at each end, and the rear headers are connected together by short sections b, and opposite each drum are openings bin the walls of the headers, provided with suitable covers b. Extending entirely through the drums are bolts b having covered nuts b which hold the covers I) in place, thus dispensin g with inside anchors. The bolts being long are supported at proper intervals by perforated plates b which are made in sections, so as to be easily applied. The upper drums are steam-drums, and the perforated plates extend the full diameter of each drum. In the present instance they are made in six sections bolted together and may be secured to the drums in any manner. The plates of the lower drums only extend up to the bolts and are secured thereto by clamps, as shown.
The plates 0 for supporting the drums are made in three sections in the present instance, the overlapping edges being bolted or riveted together, as shown in Figs. 2 and 3. Cleaning-openin gs c are made in the plates, which are provided with pivoted covers. The plates 0 also act as partition-walls to prevent the escape of the products of combustion.
The front header D is made of a series of sections d, as shown in Figs. 1 and 2. Some of these sections are coupled to six tubes, some to two, three, or nine tubes. These sections maybe of any form and may be coupled to as many tubes as desired. The end sections are provided with flanges d, and the bottom sections are provided with flanges 61 as shown clearly in Figs. 2 and 7. These flanges are bolted or riveted to a flange g on a frame G, inclosin g the front header. This frame is secured to the lower header B of the drums B, so that the strain is removed from the nipples coupling the several sections cl together and the nipple e coupling the front header to the drum-header B. The frame extends beyond the caps of the hand-hole openings and is provided with doors G, which prevent the escape of the products of combustion which would pass through the spaces between the headersections. These doors G are inside the main doors A, which, in the present instance, with the doors A inclose the entire front of the boiler-furnace. The header-sections when their corners are round may also have flanges (Z Fig. 7, at the corners, so as to entirely close the space between the several headersections, thus adding another barrier against the escape of the products of combustion.
Referring to Figs. 1 and 3, the rear header D is made up of sections in a manner similar to the front header, and the side and bottom sections are provided with flanges adapted to be secured to angle-bars II II. In the present instance the side bars II II extend up to and are secured to the manifold E, as elearl y shown in Fig. 3, so that the strain is taken off of the nipples and circulating-tubes, while the header is hung from the rear plate 0 by suspension-rods 7&- h, which are coupled at any convenient point to the header.
Both the front and rear header-sections have clean-out openings directly in front of the tubes, and these clean-out openings are provided with caps (P, which are adapted to the outside of the section, while cover-plates d are adapted to the inside of the section, as clearly shown in Figs. 5 and (3. Some of the openings are elongated and the caps are correspondingly elongated to cover more than one tube, as shown in Fig. 4.
Each cover-plate has an internal rib d, which projects into the clean-out opening for the purpose of strengthening the plate. By this means I utilize a waste-space for the strengthening-rib, and it does not interfere with the free circulation of the boiler.
Bolts (1* pass through both the plate and cap, and adapted to the bolts are nuts The heads of the bolts are set in recesses in the inside plate. I form on each end of the inside plates (1 lugs (1 which are adapted to recesses d in the header-sections. These recesses do not pass entirely through the shell of the section, but onlyso far as to allow the lug to hold onto the section and thus retain the inside cover-plate in position while the outside cap is being placed in position, as in Fig. 6. Otherwise itwould be almost impossible to centrally locate the inside plate on the front header. The lugs need not be used on the rear header, as the rake of the header is sufficient to hold the inside cover-plate in position, but itis necessary 011 the front header, as the rake is in the wrong direction.
I preferably form a head (1 around each nipple on the inside of the header-section, and I also form on both the outside and inside of the header-sections around the opening for the reception of the heating-tube ribs (Z (Z These ribs strengthen the header-sec tions to a considerable extent and allow for the formation of a tightjoint, as clearly shown in Fig. 10. This joint is stepped at d", and the tube or nipple is set into the opening, as shown in Fig. 9. A tube-expander is then inserted, forcing the tube out against the stepped portion (1, so as to form a double olnt, as shown in Fig. 10, thus making a very tight joint and one which cannot be readily pulled outby the expansion and contraction of the parts. I preferably form all tubejoints in the boiler in this manner.
\Vhen the sections are made as shown in Figs. 2 and 4, I preferably form a perforated strengthening-plate (1 across the header-section. The perforations therein are of sufli' cient size as not to interfere with the proper circulation.
The drum-headers B are preferably made, as shown in Figs. 2 and 1.1, of two struck-up plates b and I), one plate Zr having flanges to which are secured the drums B, while the other plate has the flanged opening Z) to accommodate the caps Z). The headers have braces Zr and Z1 extending from one plate to the other, as shown in Fig. 11.
Depending from each of the lower drums B are mud-collectors E. These consist of depending drums c closed at the bottom and having a vertically arranged circulatingplate 6*, which has an inclined upper end a, so as to deflect the water as it comes in from the supply-pipe I. Each mud-drum is connected to a manifold box E, as clearly shown in Figs. 1 and 3, and this box is coupled to the upper portion of the rear header by circulating-tubes c. These circulating-tubes are sufficient in number to allow for the proper circulation of the water through the boiler.
In the upper portion of the manifold box E are clean-out openings 6, provided with suitable caps, so that the circulating-tubes can be readily cleansed or removed when necessary.
The mud-drums have blow-off tubes c". In the present instance these tubes are in line and form a connection with the series of muddrums. The blow-offtubcs are provided with suitable valves.
It will be understood that when a single steam-drum is used in place of a series, or where only two drums are used one above the other, then there is only one mud-collector required.
It will be understood that the boiler is so formed that when an increased horse-power is required an additional header-section with two or more heating-tubes attached can be readily added to one side of the boiler and, if necessary, an additional set of drums can be attached; and it will also be understood that in a small boiler two drums may be used one above anotherand the numberinereased according to the horse-powerrequired.
