N-PEVERS, PHOTOlLrTMDGRAFHEn. WASHINGTON u c dilated met stent GMW HERMAN W.V LUDE-ns, 0F PH1LADELPHIA,`PENNSYLVANIA.
Letters Patent No. 94,226, dated August 31, 1869.
IMPROVEMENT IN STEAM-GENERATORS.
The Schedule referred to in these Letters Patent and making part of the same.
To all whom it may concern.-
' Be it known that I, HERMAN W. LDERS, ofthe city of Philadelphia, in the county of Philadelphia, and
State of Pennsylvania, have invented a new and usenace. The ends of "these tubes are connected with horizontal tubes in a novel manner, and provision is made for the expansion and contraction of the metal.
'lhe invention further consists in the construction, alrangement,and combination of parts as hereinafter more fully d escribed.
In the accompanying plates of drawing- Figure l represents a veit-ical longitudinal section of the boiler', through the line x a: of fig. 2, showing the position of the generating-tubes, the furnace, and the central vsteam-chamber.
Figure 2 is a frontfend elevation.
Figure 3 is a rear-end elevation.
Figure 4 is a detailed view, showing the method o connecting the inclined tubes at their ends.
Figure 5 is a cross-section of iig. 4 through the line y-y.
Similar letters ot' reference indicate. corresponding parts.
A represents lthe arch or wall, by which the generating-tubes, steam-drums, andv furnace are enclosed.
B represents the generating tubes.
As indicated in iigsa), and 3, the boiler is made in two upright sections, each system of inclined tubes being connected at each end by the T-bolt G, as illustrated iniigs. 4 and :5.
It will be seen that the heads of the T-boltsarehcld by lugs or shoulders in the tubes, 'and pass through caps 1), so thatthose. tubes are drawn by nuts E to the short sections of tubes F, which are cast on and form a portion of the horimmtal tubes G, represented in figs. 2 and 3.
H represents vertical pillar-tubes. with which the horizontal -tubes are connected.
rl'hese vertical tubes extend up from the lower tier of generating or inclined tubes, and connect at the front end of the boiler directly with the twoonter steam-drums,by curving the ends inward. as seen in the drawing.
At the rear end of the boiler, these vertical tubes H, (one of which is placed at each -corner,) are connected by a cross-tube, I, which supports the tubular stands J, which form the connection with the steamdrums.
K represents the two outside drums, and L, the middle drum.
M represents the front transverse tubes.
These, it will be noticed, are of a peculiar formation, While their lower sides are l1o1izontal,for receiving their respective tiers of generating-tubes, their upper sides incline upward toward the vertical corner tubesl H, so as to allow of a free discharge of steam from the generating-tubes.
N represents the rear transverse tubes, which rest in a horizontal position.
These tubes are cast in longitudinal sections, which are connected by ball-and-socket joints, secured together by bolts, which run through the sections from the centre, and through the vertical tubes H, on which they are fastened by screw-nuts, as seen in the drawmg. v
The steam will be discharged from the elevated ends of -the generating-tubes into the transverse tubes m iomthence into the frontupright pillar-tubes H, and from thence into the two outside steam-drums K.
At the rear end of these drums it will be seen that they are connected with .the middle drum L by the transverse pipe O, and the steam finds its Way into the drum'L, through this pipe O.
`This cross-pipe O is so elevated that the water,
Iwhich is carried up with the ,steam into the two outside druins K, will descend into the vertical tubes, and
' lind its proper level in the boiler, thus producing a circulation in the boiler.
The steam, after enteringthe drum L, is discharged for use from the pipe P, at the front end of the boiler, and on its return through the central drum, it is thoroughly dried and prepared for use.
The water is introduced into the vertical tubes H, at lthe back end' of the boiler, through the crosspipe It.
S represents Cthe furnace or lire-box.
l is the bridge-wall. x I
The smoke and unconsumed products of combustion pass from the boiler through the aperture U at the rea-r end.
By making the rear horizontal tubes in sections, and connecting them by lball-and-soc'zket joints, the rigidity usually so ruinous to tubular boilers is avoided,
expansion and contraction being thereby provided for. p
It will be seen that the generating-tubes are so connected with thel horizontal tubes that any one of them may be removed for repairs or exchange without disturbing the others; that a thoroughand active water- 'circulation is kept upjthrough the generating-tubes and the outside drums.
The generating-tubes may bc readily exchanged as Y pillar-tubes H, the transverse tubes m and n, and the drums K K and L, combined and arranged substantially as herein shown'and described.
2. The arrangement of the steamgenerating tubes,
wherebyany one may be removed, exchanged for 'another, turned over, or changed end for end, substan, tially as described.
3. ln combination with a tubular boiler, the end tubes m, with inclined uppersurfaces, and the sectional end tubes u, connected by ball-and-socket joints, sub stantially as described.
HERMAN W. LDERS.
