IFEEDmATER HEATER.
SPECIFICATION forming part of Letters Patent No. 319,376, dated June 2. 18851 Application filed March 5, 1885.
To @ZZ whom t may concern.-
Beit known that I, WILLIAM H.- WooD, of New York, State of New York, have invented certain new and useful Improvements in Feed- Water Heaters; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specication, and in which- Figure lis a vertical section of my improved feed-water heater. Fig. 2 is a vertical elevation ofthe heater when put together. Fig. 3 is a plan lo1" the heater A B. Fig. 4 represents an enlarged drawing ofthe expansion-ring B. Fig. 5 represents an enlarged drawing of the ex,- pansion-ring A.
Like letters of reference indicate corresponding parts in all the figures.
The object of my invention is to im prove the construction of jacket and other feed-water heaters 5 and its nature consists of the more eiectual means for providing for the contraction and expansion of the steam pipes or iues in which the exhaust-steam imparts its heat to the water surrounding them, and in providing the said pipes or flues with independent pipeplates in which the pipes are expanded; in providing an expansion-ring for them and one for the casiuginclosing the pipes; in ascum apparatus for the removal of scum; in pro- Viding a cast-iron base for the heater, with inlet exhaust-pipes cast in it, and an angular bottom for directing the sediment and ldirt to the pipe for its removal, and in combination of parts hereinafter more fully described.
Under the varying circumstances in which feed-water heaters are subjected it is found almost impracticable to keep the steanrpipes tight, owing to the rigid method of securing them in the pi pe-platcs in which they are eX- panded. My invention is to provide for the expansion-rings A and I3, which are preferably rolled in weldless rings. A is secured to the face of the exhaust-pipe D and to the pipe-plate C, and the expansion-ringB is riveted to the inside casing, E, which is secured to the pipe-plate C', thus allowing the pipes P free expansion and contraction.
The outside casing, F, covering the inner casing, E, forming space for the steam to escape after passing the steam-pipes I), is pro- (No model.)
vided with outlet-pipe G and man-hole H, for
allowing hand-plate J to be removed from the inner casing, E, to examine the expansionring A.
As the water is heated in the inner casing, E, the scum and other light particles rise to the top of cylinder, from which it can pass oft` through the pipe `S into the scum apparatus K, so that the scum will be removed through pipe L, keeping the water clear and clean. The heavy particles and sediment contained in the water will sink to the bottom of the cast-iron base D, and can be taken ott through the pipe L. The cold water is admitted through the pipe IVI and the hot water is taken out through the pipe N, and the eondense-water from the exhaust-pipe D is taken of through the pipe O.
The proportions of the completed heater will be varied according to the size of the boilers with which they will be used, and according to location or peculiar surroundings, which will somewhat vary the location of the pipe-connections, and the whole will be supported on a cast-iron base.
Having thus described my invention, I claim and desire to secure by LettersI Patent of the United Statesl. In a feedswater heater, the combination of the expansion-ring A, the exhaust-pipe D, and the pipe-plate C, substantially as for the purpose shown and set forth.
2. In a feed-water heater, the combination of the expansion-ring B, riveted to the casing E, with the pipe-plate C and casin g E, substantially as for the purpose shown and set forth.
3. In a feed-water heater, the combination of the pipeplates C and C with the casing E, expan'sioirrings A and I3, and the exhausti pipe D, substantially as shown and set forth.
4. In combination with heatencasing E, the expansion-ring B, the steam-pipes I), the pipeplates C and C, with the expansion-ring A, and the east-iron base D, having angular bottom, substantially as for the purpose specified and set forth.
In testimonyT that I claim the foregoing as r
