EDVARD J. MOORE, OF PHILADELPHIA, PENNSYLVANIA.
S-TEAM-BOILER.,
SPECIFICATION forming part of Letters Patent No. 605,791, dated June 14, 1898.
Alipnoauon filed July 21, 1397.
To all whom it may concern.-
Be it known that I, EDWARD J. MOORE, a citizen of the United States, residing in Phila-A delphia, Pennsylvania, have invented certain Improvements in Steam-Boilers, of which the following is a specification.
The object of my invention is to improve the construction of water-tube boilers and dispensewith the ordinary stays within the drums. This object I attain in the following manner, reference being had to the accompanying drawings, in which- Figure 1 is alongitudinal sectional view of my improved boiler. Fig. 2 is a sectional plan view on the line 2 2, Fig. 1. Fig. 3 is a longitudinal sectional View on the line 3 3, Fig. 1. Fig. 4 is a transverse section on the line 4 4, Fig. 1. Fig. 5 is a transverse section on the line 5 5, Fig. 1-. Fig. 6 isa transverse section on the line 6 6, Fig. 1. Figs. 7, 8, and 9 are detached perspective views of the drums. Fig. 10 is a perspective view of the crescent gusset-piece.
A is the boiler-casing, preferably made of brick, and BB yB2 are kthree longitudinal drums, which 'are connected together by vertical water-tubes.
C is the iire-'chamber, and C' is the ash-pit. c
` are the gratefbars, and A' is'the bridge-wall.
. Back o f the bridge-wall and extending intol the rear wall of the boiler is the lower drum B, ofthe form shown in Figs. 1 and 7. This drum B has a circular end section b and a iiat tube-plate b. The heads h2 b3. h4 are dished and are Vsecured to the plates of the drum, so as to make-a rigid construction, dispensing with internal stays.l f
Directly above .the'giire-chamber and the drum B is the intermediatedru'm'B, Figs. 1 and 9. The front vportiond of this drum-is circular, and the upper'tube-plate' d is iiat, and the portion d2 extending above the fire chamber is semicircular, While the portion d2 directly above the drum B is iiat for the reception of tubes D, which extend vertically from the tube-plate b' to the tube-plate d2. These tubes are so spaced that any one of them can bereadily. removed without disturbing the others, and in order to provide for the ready .removal of the'. tubes I place nipples D in thetube-plate cl2, so that when Serial NoI 645,433. (No model.)
a tubeis removed the nipple will allowr for the removal of the tube within the plate.
The heads d?, d5, and d of the drum B are dished in the same manner and for the same purpose as the heads of the drum B, so as to dispense with stays, and by making the drum semicircular ata point directly above the irechamber I give the drum sutiicient strength to dispense entirely with the stays at this point. The vertical tubes connected to the other part of the structure stay the drum sui",- ciently.
The gusset-piece d7, Fig. 10, unites the semicircular portion d2 to the portion d2, the flange d8 being secured to the portion d2 and the flange di to the portion d3 and the curved side portion of the drum.
.Mounted above the drum B is a drum B2, which may be the steam-drum of the boiler. This drum is of the same form, only inverted, as the drum B, a portion of the drum at the rear end e being cylindrical, the tube-plate e at the bottom being fiat, so as to receive the vertical tubes E, and the upper portion e2 is semicircular throughout its entire length. The heads e2 e4L c5 are dished in order to It will be seen that by thisconstruction I pro-'f vide a short longitudinal lower drum and two long longitudinal drums, one above the other. The two upper drums extend over the firechamber. These drums are connected together by the vertical tubes, so that the products offcombustion will pass from the firechamber between the drums B and B', then around the rear endv of the drum B and betweenthe drums'B and B2 and then around thefront end of the drum B2 over the drum B2 to the passage a2, which communicates with the stack.
In some instances the products of combustion may escape at the front of the furnace to the stack without passing over the drum B2; but I prefer the construction shown.
. I connect the forward ends of the drums B and lB2, with a circulating-tube F, (shown clearlyin Figs. 1 and 4,) and I connect the vstrengthen the drum in the same manner as IOO rear end of the drums B and llby a circulating-tube G. This tube has an extension GH, which passes into the drum B to a point near the bottoln, so that the circulation will be more complete.
Each drum has a series of brackets [,which extend over bearing-plates L", and between the brackets and the bearing-plates are balls i2, so as to allow for expansion and contraction. rlhe lower drum B has also a bracket at its forward end, supported by balls in the same manner as the side brackets, as shown in Fig. 1.
I extend the semicircular portions of the drums past the center, so as to give better facilities for expanding the tubes; but I do not extend them sufliciently so that the drums will need inside bracing. Under the drinn B', in advance of the gusset-piece (Z7, I form an arch Ato add to the support of the drum and to form with the bridge-wall A the throat through which the products of combustion pass to the space between the drums B B.
I form a space between the main body ot the lower drum and the side walls of the furnace, as shown clearly in Fig. 5, so that the products of combustion can come in contact with all portions of the drum, and I form a space between the lower portion of the rear section of the drum B'for the same purpose.
I provide vertical dellecting-plates II at each end of the boiler between several of the vertical tubes E, Fig. 2, so as to divert the gases, making them pass through the combustion-chamber in a serpentine path, so that the tubes will be more evenly heated.
lVhen the upper drum is the steam-drum, the water-level is a short distance above the tube-plate, and by connecting the lower drum B in the manner shown I am enabled to utilize this lower drum as the mud-drum and provide means for blowing out the mud from this drum through the blow-off pipe f. g is the feed-water pipe communicating with the upper drum, as shown in Fig. 1.
Each of the drums is provided with a manhole-opening, suitably capped, so that access maybe had to anyone of the drums or to the spaces at the front aud back of the boiler, thus making it a boiler that is readily accessible from all points.
In some instances the upper drum and tubes may be omitted, in which case the upper portion of the central drum will be circular and will connect with the steam-pipes.
I claim as my inventionl. The combination in a boiler, of two or more longitudinal water-drums 011e mounted above another, water-tubes connecting the drums, the lower drum being short, with a nre-chamber in advance of said lower drum, substantially as described.
2. The combination in a boiler, of three longitudinal drums, one mounted above another, vertical tubcs connecting the central drum with the top and bottom drums, the bottom drum being short, with a lire-chamber in front of the bottom drum, substantially as described.
3. The combination in a boiler, of three drums, tubes connecting the central drum with the top and bottom drums, a fire-chamber in advance of the bottom drum, the central drum terminating short of the top and bottom drums so as to allow for the passage of the products of combustion around the end of the central drum, substantially as described.
4. A steam -boiler drum semicircular in cross-section and having a tube-plate on its ila-t side, and a short circular section at one end, substantially as described.
5. A steam -boiler drum semicircular .in cross-section and having a tube-plate on its flat side, and a short circular section at one end, with dished head at each end, substantially as described.
6. A steam-boiler drum having one portion semicircular in cross-section, the circle extending beyond the center and having a dat tube-plate coupling the two edges of the semicircular portion, substantially as described.
7. A drum for a boiler having a long tubesheet extending nearly the full length of the drum, and a short tube-sheet connected to the long tube-sheet at one end by curved side plates, and a semicircular section coupled to the other end of the long tube-sheet and secured to the short tube-sheet by a gussetplate, substantially as described.
8. A gusset for a steam-boiler in the shape of a crescent having a flange extending in one direction Jfrom the upper portion of the gusset and alange extending in the opposite direction from the opposite portion ol' the gusset, said flanges being attached to the boilerplates, substantially as described.
9. The combination in a steam-boiler, of; three drums, tubes connecting the central drum with the upper section and with the lower section, with a lire-chamber in advance of the lower drum, the portion of the central drum above the nre-chamber being semicircular in cross-section, substantially as described.
