UNITE a STATES IRVING M. SCOTT, OF SAN FRANCISCO, CALIFORNIA.
FEED-WATER HEATER.
SPECIFICATION forming part of Letters Patent No. 245,229, dated August 2, 1881,
Applicationfiled May 19,1881. (No model.) I
To all whom it may concern:
Be it known that I, IRVING M. Scor'r, of the city and county of San Francisco, State of California, have invented an Improvement in Feed-Water Heaters; and I hereby declare the following to be a full, clear, and exact description thereof.
My invention relates to that class of heaters which are used to furnish water to steam-boilers, and are known as feed-water heaters.
It consists in a novel arrangement of pipes and chambers, through which the water is forced, being all the time exposed to the heat of the waste steam which surrounds the said pipes, all of which will hereinafter be more fully described.
Referring to the accompanying drawings, Figure 1 is a vertical section of my invention. Fig. 2 is a horizontal section through boiler on line a a. Fig. 3 is a horizontal section on line to a Fig. at is a horizontal section on line y 2. Fig. 5 is a section of the water-pipes.
Let A represent the casing, having on its top the cap or hood B, with an entrance-pipe, C, as shown. In its base is fitted an upper diaphragm, D, and a lower diaphragm, E, thus forming between them a space or chamber, G, and between the lower diaphragm and the base of the casin g is formed the lower space or chamber, H. These spaces are divided into four separate compartments by the vertical diaphragms or partitions F F, being plates crossing each other at right angles. The first of these compartments in the lower chamber or space I have marked a, and the compartment above it, in the upper space, a,- the second lower one, I), and second upper one, D,- third set, 0 and c,- fourth, d and (1.
Between the upper compartments a and b there is an open connection, as shown at 6. Between the lower compartments 1) and 0 there is also an open connection at f. Between the upper compartments 0 and cl there is an open connection at g. Opening into thelower compartment a is the feed-pipe J. From the lower compartment (1 proceeds the discharge-pipe K.
L is the blow-off, opening out of the lower compartment cl.
Within the casing A are the water-pipes, consisting of the inner pipes, M, and outer pipes, N. All the inner pipes proceed through the upper diaphragm, D, upper chamber, G, and lower diaphragm, E, and open into the compartments of the lower chamber, H. The outer pipes, N, proceed through the upper diaphragm, D, and open into the compartments of the upper chamber, G. The outer pipes, N, iuclose the inner pipes, M, and are enough larger to form a water-space between the two pipes. The pipes N extend a short distance above the tops of the inner pipes, M, and are provided with caps 2', thus closing them above. The inner pipes, M, open into the outer pipes, N, above, as shown. I can have as many of these double pipes as desirable.
In the middle of the casing A is the exhaustpipe 0, extending down nearly to the upper diaphragm, D. The double pipes M N surround this eXhaust-pipe and occupy the space between it and the casing.
The operation of the device is as follows: Water is forced in through the feed-pipe J. It enters the lower compartment a, and having no outlet but through the inner pipes, M, is forced up to their tops, and thence it comes down through the outer pipes, N, into the upper compartment a. It then flows through c into the upper compartment 1), and up through the outer pipes, N, and down through the inner pipes, M, into the lower compartment 1); thenee through f into lower compartment 0, and up through the inner pipes, M, down through the outer pipes, N, into the upper compartment 0; thence through 9 into upper compartment (1, and up through the outer pipes, N, down through the inner pipes, M, into lower compartment (1, from which it is discharged through K, having completed the circuit. The waste-steam is admitted through the pipe C at the top of the casing A, and occupies the space within the casing surrounding the water-pipes, and thus heating the water. The steam is exhausted through the pipe 0. The travel of the water through the pipes and the great surface exposed to the action of the steam will cause the water to become sufficientl y heated to be fed to the boiler.
The details of construction of the device may be accomplished in any suitable manner. I have here shown the top B as bolted to the casing, and the chambers below being made in one casting and bolted to the casin g. Appropriate hand-holes are provided. The pipes M and N are screwed into their respective diaphragms, so that they may be easily removed for cleaning or the substitution of others. The caps i are screwed on the pipes N, and the exhaust O is supported by a flange, as shown.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. The feed-water heater consisting of the casin g or shell A, having a steam-inlet, O, and pendent exhaust-pipe 0, having its port at the lower central portion of the steam-space, the upper and lower water spaces or chambers, G and H, said spaces being divided into separate compartments having connection with each other, as shown, and having a feed-pipe, J,
and discharge K, and the double pipes M and N, when arranged substantially as and for the purpose herein set forth.
2. In a feed-water heater, the combination of the double water-pipes N and M, arranged with relation to each other as shown, and the water-spaces G and H, having separate compartments a b c d a b c at, said compartments
