FEED-WATER HEATER.
SPECIFICATION forming part of Letters Patent No. 531,756, dated January 1, 1895.
Application filed May 10, 1893. $erial No. 473,657. (No model.)
To (ZZZ whom it may concern.-
Be it known that we, ERASTUS W. WHIT- LOCK and 'WILBUR L. SHEPARD, citizens of the United States, residing at Elmwood, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Feed-"Water Heaters, of which the following is a full, clear, and exact specification.
The invention relates to. the class of tubular coil heaters which utilize exhaust steam for heating water before it enters an engine boiler; and the object is to provide a simple and compact heater, constructed of the most desirable materials in the most economical and perfect form, with the parts readily put together without joint in the interior, so that the heater will not leak, while allowing for all expansion and contraction, the only joints being on the exterior where they can be readily removed and repacked without disconnecting the feed pipes.
To this end the invention resides in details of the construction of the coils, and their connections, as more particularly hereinafter described and pointed out in the claim.
Referring to the accompanying drawings: Figure 1 is a central longitudinal section of a heater formed according to the improvement. Fig. 2 is a plan of the same with the top removed. Fig. 3 is a plan of one of the fittings and the joint used. Fig. a is a horizontal section of the same, and Fig. 5 is a detail perspective view of one of the coil holding clamps.
The cylindrical exteriorshell of iron, steel, or other material, is set on legs either vertically or horizontally, depending upon the locality in which the heater is to be placed. This shell is flanged at its ends, and tightly bolted thereto are the heads 1. In the heater shown, both of the heads are perforated, one being arranged to receive the inlet 2 for the exhaust steam, and the other the outlet 3 but of course it is really only necessary that there should be an inlet, if a drip pipe for the condensation is provided. In the interior of the shell are placed a plural number of coils of pipes, these usually being copper tubing without joint or seam, bent into spiral coils;
and the ends of these coils are Welded, brazed or otherwise fused to the fittings 4:. These fittings are usually cast to shape of gun metal with integral nipples 5 to which the ends of the coils are brazed or welded, so as to be practically integral therewith. The stems 6 of the fittings are flanged and threaded on the interior and the exterior. The shell is perforated near each end to receive the stems of the fittings, the flanges preventing the fittings from passing entirely through gland nuts 7 being screwed on the exterior thread of thestenos of the fittings, after asbestos or other packing has been placed in the packing grooves or sockets made in the outside of the shell around the fitting perforations. The inlet and outlet pipes are threaded and screwed into the interior threads of the stems of the fittings, so that the nuts can be removed at any time to repack the joints, without disturbing the connections.
In the interior, and extending from the top to the bottom of the shell, usually placed outside of each coil, are tie-rods S, that are usually narrow strips of metal; and bolted to these strips are the clamps 9 that partially encircle and hold the coils. These clamps consist of a smaller portion 9 that rests against the rod, and a lar er portion 9 that encircle portions of two spirals of the tube, the two parts of the .clamp being held together and to the strip by means of abolt 10. Every other space between the spiral coils is left unoccupied, to allow for the expansion and contraction of the coils.
By means of the above described construction, a heater is produced which is simple, cheap, compact and adds but little to the resistance of the flow of the feed water, while it presents a large surface to the heating action of the exhaust steam. The interior tubing and the fittings are practically homogeneous, there being no joint or seam within the shell, which can leak under the strains produced by the different conditions when 5 heated and cooled. The coils are formed to expand and contract, and yet are clamped together by the clamps in such manner that there is no vibration or shaking when the water is boiling. The coils are easily inserted into the shell, with the ends of the fittings projecting through, and the gland nuts readily screwed in place on the end of the fittings to make tight joints; and these In a feed water heater, in combination, a
shell having a steam inlet, a feed water inlet and a feed water outlet, each having a stem passing through the shell one near the top and the other near the bottom, and proecting nipples in the interior of the shell, the bodies of said fittings increasing in size from the interior outward at each nipple from the capacity of the inner of the coils used to a capacity equal to all of the coils used, and a plural number of coils of jointless tubing integrally connected with the nipples of the fitting between which they extendwithout joint, substantially as specified.
