SFECIa-'ICATION forming part of Letters Patent No. 339,983, dated April 13,1886. Application lcd December 29, 1885. Serial No. 187,046. (No model.) Patented in England July (i, 1885, No. 8,178.
To @ZZ whom, z5 may concern,.-
Be it known that I, EDWARD GREEN, asubject of the Queen of Great Britaimresiding at NVakeiield, in the county of York, England, have invented new and useful Improvements in Feed-Tater Heaters, (for which I have obtained a patent in Great Britain, No. 8,178, bearing date July 6, 1885,) of which the following is a specification.
The objeetofthis invention is certain new or improved details of fuel-economizers, whether for heating the feed-water or for generating steam, and it consists- First. In separating one or more pipes from the others ofthe series by a partition or diaphragm inthe upper box, or byadisconneetion ofthe pipes, so that the Coldwater-feed pipe, which is at the top, allows the water to pass down tubes from one side ofthe partition and up the other tubes at the other side of the partition. The tubes up which the water iiows are greater in number than that of the feed, whereby thel water is broken into many streams and is therefore quickly heated before it leaves the apparatus or is rapidly converted into steam.
Second. In forming the lower box deeper at the outer or exposed end than at the inner end, for the collection of sediment,and in iilling said exposed part with a sludge-cock for blowing-off purposes.
Third. In dividing the lower box into two compartments by an internal inclined wing, so that the sediment from the water in the tubes may slide from the upper compartment into a lower one, in which it can accumulate and be removed at intervals,as desired. Portions may be of pipe shape.
Fourth. In making the boxes, top and bottom,or one of them only, of separate castings, and providing them with tlanges by which any two may be bolted together, the pipes and their sectional boxes being interchangeable.
The details of my invention will be understood by reference to the annexed drawings, in which at Figure l I show a sectional elevation of the upper box of a fuel-economizer, with a partition or diaphragm, A, in said upper box, B, and with the cold-water-feed inlet C, so that the water entering at G may flow down the first row of the series of pipes D into the lower box and then up into the pipes E,
which are at the other side ofthe partition A, into the upper box, B, and away by the outlet G, to convey the hot feed-water to a boiler, if the apparatus be used for heating feed-water, but if used as a steam-generator the upper box, B, would form the steam-space, the steam generated being` taken by the pipe G or in other convenient manner. The partition or diaphragm A may be formed iu the casting of the upper box, B, or affixed within it in any suitable manner so as to separate the feedwater space H from the hot-water portion I of the upper box,or the feed-water entry may be by a separate pipe, C, not forming part of the upper box, B, as at Fig. 2, the upper box, B, having a series of pipes, E, attached in the usual manner.
The second part of my invention is shown at Fig. 3, in which the lower box, F, is made with an inclined bottom, J, with a deeper portion at or near the outer or exposed end than at the inner, so that the sediment which deposits itself in said box may tlow to the deeper part J ,from which it can be readily removed on opening the sludge-cock at K. Lis acoverplate which can be removed to permit of the lower box, F, being cleaned out.
The third partofmyiuvention is represented at Fig. 4, the lower box, F, being dividedinto two compartments, M N, by an internal inclined wing, so that the sediment which deposits itself upon the surface forming the bottom ofthe up per compartment, M, in the box may slide down said inclineinto the lower compartment, N,within which it can accumulate. The lower compartment, N, is also inclined so that the sedimentaccumulating therein may slide to the outer or exposed portion of the said boxso as to be blown out by the sludgecock K, or be otherwise removed.
Instead of the upper or lower boxes being made from a single casting, they may be in separate castings, as at Fig. 5, having one vertical pipe to each upper and lower box,'or they may be in pairs,as at Fig. 6. Each upper and lower box may have two sockets for two vertical pipes, or they may be otherwise arranged, the boxes both top and bottom being interchangeable and capable of being bolted together to form the requisite size of fueleconomizers.
The several detail improvements hereinbelOO fore described are applicable in most cases to be used one with the other, butv they may be used separately, or any two of theni may be used in conjunction, as desired.
I claim as my invention` 1. The combination, with the series of pipes D and E, the upper box, B, and the water-iulet pipe C,communicating with the pipes D, of the diaphragm A,located in said box between the inlet-pipe C and pipes D, and the series of pipes E, substantially as described.
2. In a feed-water heater, the combination, with the upper and lower boxes, Band F, and connecting-pipes E, of' the inletD for the cold Water to the lower box, said inlet being;r disconnected from the upper box, substantially as described. f
3. The combination. with the upper box, B, inlet-pipe C, and series of pipes E and D. of the lower box, F, having au inclined bottom wall, J, to widen the box at its outer end, and l a sludge-cock, K, connected with said widened outer end, substantially as described.
4. The combination, with the upper box, B,
inlet-pipe C, and series of pipes and D, of 25 thev lower` box, E, having an inclined bottom Wall, J, the inclined wing located in the lower box to separate the same into two compart- Aments, and a sludge-cock, K, connected with EDWARD GREEN,
