IMPROVEMENT IN FEED-WATER HEATERS FOR STEAM-BOILERS.
Specification forming part of Letters Patent No. 210,846, dated December 17, 1878; application iiled October 28, 1878,
To all whom it may concern:
Be it known that I, BENJAMIN FORD, of Union township, in the county of Allegheny and State of Pennsylvania, have invented a certain new and useful Improvement in Feed- Water Heaters for Steam-Boilers; and I do hereby declare` that the following is a full, clear, and exact description thereof', reference being had to the accompanying drawings, and to the letters of reference marked thereon.
This invention relates to improvements in the class of devices applied to steam-boilers whereby the feed-water will be raised to the desired temperature before it commingles with the water below in the boiler.
My invention consists in the combination of alongitudinal swinging trough or chamber, longitudinal pipe, provided with longitudinal slots, and longitudinal crown-piece, constructed, arranged, and operating with relation to each other and a feed-pipe and boiler.
It further consists in the combination, with a feed-pipe, crown-piece, and trough or chainber, of slotted pendants and set-screws, all as will be hereinafter fully described.
To enable others skilled in the art with which my invention is most nearly connected to maire and use it, I will proceed to describe its construction and operation.
.In the accompanying drawings, which form part of my specication, Figure l is a side elevation oi' a steam-boiler furnished with my iinprovement in feed-water heaters. Fig. 2 is a top view of the slotted pipe which is attached to the water-supply pipe. Fig. 3 is a transverse section of the heater at line y of Fig. 1. Fig. 4 is an end view of the heater.
In the accompanying drawings, A represents an ordinary steam-boiler, and B the watersupply pipe, to the inner end of which is attached, at right angle, a longitudinal slotted pipe, C.
Over the slots e of the pipe C is placed a longitudinal crown, D, from each end of which is a slotted pendant, f, to the lower ends of which is attached the longitudinal receiving trough or chamber g by means of set-screws 7L.
By means of the slots in the pendants f and the set-screws h, the chamber or trough q can be adjusted vertically or swung on its pivots or screws, so as to have the water flow over its top edges evenly.
By the use of the slotted pipe C the water is discharged through the slots c against the crown I) in a thin sheet, and, spreading over it, drops from its edges/i in thin sheets into the chamber g, from which it flows over theedges of the trough or chamber g in thin\ sheets, and passes down through the steam, and commingles with the water in the boiler.
By constructing the water-heater as hereinbefore described, cold water will never be brought in contact with the inner surface oi' the boiler, and the distributing-pipe C will never become clogged, and when undue pressure of water is forced into itit will cause the slots to open up, and the discharge is thrown against the crown and spread, as hereinbefore stated.
Having thus described my improvement, whatI claim as of my invention :is-
1. The combination of the swinging trough or cham ber g, longitudinal pipe (l, provided with longitudinal slots e, and longitudinal crownpiece I), constructed, arranged, and operating, with relation to each other and the feed-pipe B and boiler, substantially as hereinbefore described, and for the purpose speciiied.
2. The combination, with the feed-pipe B, crown-piece I), and trough or chamber g, of the slotted pendants j' and set-screws 7L, substantially as and for the purpose herein shown and described.
y BENJAMIN FORD.
