Description
""oneoi more tubes in each bar as shown in NITED STATES PATENT OFFICE..
JOS. GODLING, JR., AND JNO. MCCUNNIFF, OF FAIRBANKS, IOWA.
FEED-WATER HEATER FOR STEAM-BOILERS.
Specification of Letters Patent No.
To all whom it may concern:
Be it known that we, JOSEPH CODLING, Junr., and JOI-IN MCCUNNIFF, of Fairbanks, in the county of Buchanan and State of Iowa, have invented a new and useful Improvement in Feed-Vater Heaters for Locomotive-Boilers; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l, is a longitudinal vertical section of a locomotive grate with our improvement applied. Fig. 2, is a transverse vertical section of the same.
Similar letters of reference indicate corresponding parts in both igures.
Our invention consists in the employment in combination with hollow grate bars, of copper tubes passing longitudinally through the said bars and connecting with transversely arranged cylinders or boxes which are arranged below them at each end, and provided with connections to the feed pump and tank, as hereinafter described.
To enable others skilled in the art to make and use our invention we will proceed to describe its construction and operation.
In applying our invention we do not propose generally to apply it to all the grate bars of a furnace, but only to two or three bars at each side, as shown in the drawing.
A, A, are the hollowr bars and B, B, the tubes passing, longitudinally through them,
Fig. 2, of the drawing. The said tubes descend in a curved form, from the ends of the bars to connect with the tops of the transversely arranged cylinders C, C., of which there is one ateach end of each series of tubes.
To the bottoms of each of the cylinders C, which are arranged at the end of the grate, nearest the head of the locomotive there is attached a pipe D which descends and is curved in such a manner as just to clear the bottom of the iire-box and is provided with 27,271, dated February 28, 1860.
a iange a; to make the connection with one of the feed pumps. To the bottom of each of the other cylinders C', C, there is attached a pipe D, curved like D, said pipe being intended to have a detachable hose connection, with the tank of the tender. The pipes D and D, are intended to project a short distance upward into the cylinders C, C', to allow sand or other solid sedimentary matter contained in the water to collect around them, and hence the said cylinders, constitute sediment collectors as well as serving to supply the water to the tubes B, B, and receive it therefrom for conveyance to the feed pumps. The sediment may be removed from the cylinders C, C', from time to time by taking off one end of each.
The water is drawn from the tank through the pipes D', cylinders C', tubes B, B, cylinderC, and pipe D, as indicated by the arrows, by the action of the pump and in passing through the tubes B, B, has its tempera ture very considerably raised so that it is delivered into the boiler hot. The advantages of the employment of this system of tubes and boxes over the passing of the water directly through the bars themselves, is, that the copper tubes are less liable to scale, and will not be cracked by admission of cold water in case of their having become hot and dry by the disconnection of the tender while the lire is up, and that better provision is afforded for the collection of any sedimentary matter.
That we claim as our invention and desire to secure by Letters Patent is The employment in combination with hollow grate bars, of a system of tubes B, B, and cylinders or boxes C, C., and connecting pipes D, D', the whole arranged substantially as herein specified.
