CHARLES D. SMITH, OF NEW YORK, N. Y.
FEED-WATER HETER AND STEAM-GENERATOR.
SPECIFICATION forming part of Letters Patent No. 225,537, dated March 16, 1880,
' Application filed August 9, 1879.
To'lll whom it may concern Be it known that I, CHARLES D. SMITH, of
New York, in the county of New York andl State of New York, have invented certain new and useful Improvements in Feed-Waterl Heater and Steam-Generator, of which the following is a specification. f
This invention relates to `that class of de-` vices for water and steam heaters and circu-1 lators in which the bridge-wall itself forms al `portion of s'uch water and steam circulator,l and connects, by means of aseries of steam` coils and pipes, with the water `and steamI spaces of the boilers, and also with 'the service l or feed pipe. i
Its object is to produce a more thorough and vigorous circulation of water in the boili ers to heat the feed-water before its introduction into said boilers, `and also to act as an auxiliary steam generator from the large amount of heating-surface which it affords; and to this end it consists, rst,in a vertical pipe-coil within the walls of a furnace upon one or both sides of a boiler, running the full grate-bars, communicating by means of suitable connections with the steam and water spaces of a boiler, and provided with a blowoff cock or exitoutside of said furnace-wall to clear its pipes when fouled, third, in two or more vertical `manifoldsarranged so as to extend above and below the grate-bars and within the furnace-walls, situated between two boilers, with-the steam and water spaces of which each manifold communicates by means of suitable connections, and having between them a suitable box filled with non-conducting material, or aplate', for the purpose of shutting off the heat and preventing its transmission to the adjacent manifold and boiler and resultant waste when only one of the two `boil.
ers is used; fourth, in a vertical steam and water coil running from below the grate-bars and above the water-line of a boiler, provided with connections for the purpose of carrying away the steam to the boiler and bringing the feed-water from the drum or bridge-wall into the coil, the coil being connected with the drum or bridge-wall, induction feed water pipe, and with the steam-space and waterspace of the boiler 5 fifth, in a horizontal coil located between the.bridgewall or drum and rear wall of afurnace beneath the boilers, and connected with the drum and with the waterspaces and the steam-spaces of the boilers, and provided with suitable branch pipes at proper intervals in the coil for carrying steam to the boilers; sixth, in a series of brick columns or a brick wall capped by an iron plate running from the `bridge-wall back to the rear end of a boiler 'for the purpose of supporting a horizontal steam-coil connecting with a bridge-wall and a boiler or boilers.
In the accompanying drawings, Figure l represents a detached view, in perspective, of one of the boilers with a portion of the furnace-walls and Valso of the boiler broken away, and alsoshowing its various connections. Fig. 2 is a view, in perspective, of one ofthe boilers with a portion ofi-ts walls broken away, and also showing `its various connections. Fig. 3 is a view, in perspective, of one of the boilers with a portion of its wall removed, and also showing its various connections. Fig. 4 is a plan view of all the boilers, a portion of their walls being broken away to show the' part-s beneath, showing the boilers and their connections in situ. Fig. 5 is a cross-section of the furnace, taken from behind the drum, showing the boilers n site.
Similar letters indicate similar parts of the invention.
The brick walls of the furnace are represented at A, while A `indicates the furnacedoors, behind which are the grates upon which the fuel is consumed beneath the boilers. The doors of the ash-pits beneath the grates are shown at A, while the grates themselves are shown at a.
A series of steam-boilers are shown at B, B',

wall passing transversely across the furnace from side to side and through the walls ot' the same, through which the steam and feed-water pass, and below which the inner ends of the grate-bars a are supported in any suitable manner.
From the combined drum and bridge-wall C springs a branch pipe, as shown at G, with returnbends, and terminating in pipe C, which passes through the rear wall of the furnace, rises upward, and enters the boiler B at the boiler -head above the waterline. The pipe G is furnished at its lower end with a blow-off cock.
From one of the bends or elbows of branch pipe C rises a steam-pipe, c, which passes through the side wall ofthe furnace, rises upward, and enters boiler B above the steamspace. thus conveying steam from the said branch pipes at intervals to the boilers.
At c is shown an auxiliar 1 pipe, which springs from the drum or bridge-wall C, and conveys steam from it to the boiler B.
D represents a stack or coil of steam-pipes arranged horizontally between the boiler B and the side of the ,furnacewall. This coil commences with an elbow, d, rising above vboiler Band communicating with its steamspace, and consists of a series of horizontal pipes connected by return-bends. The first of these horizontal pipes extends from the vertical portion of the pipe d3, which enters the boiler from a point at about the middle of the side wall of the furnace, to return bend near the front wall of the furnace. The next four of these horizontal steam-pipes extend the whole length of the side furnace-wall, the lower or fourth one resting upon the drum C, while the two lowest pipes of the coil are short ones, extending horizontally between the drum C and the front wall of the furnace. The lower pipe of the coil runs belowv the level of the grates a, while the lowest pipe of all passes through the front wall of the furnace, turns upward by means ofthe elbow shown at di, and enters the water-space of the boiler B through the boiler-head by means of the double elbow shown at d.
E,Fig. 2, represents a manifold set bottom upward, so that its columns e stand with their ends, caps, or plugs down-ward below the gratebars a, and connected to a lower horizontal pipe, c', by means of nipples or tees tappedin or connected with it by any suitable device. This lo'wer pipe, e', passes through the front or side wall of the furnace and ends in the blow-off cock 2, for the purpose of cleaning the pipes of the manifold when they are fouled. This manifold E is set between the boilers B and B', its lower pipe resting upon the ioor of the furnace, while its upper horizontal pipe, c", connects at one end with the steam-space of the boiler B. The other end passes out over the front wall ofthe furnace, andby means of two elbows enters the water-space of the boiler B through its front boiler-head.
At F are shown two manifolds or sets of steam-pipes connected together at the bottom by means of the horizontal pipes shown at f,
rest near the furnace-floor. The lower horizontal pipes shown at f pass through the front wall of the furnace A, and rising vertically upward enter the water-spaces of boilers B and B by means of elbows through their respective boiler-heads, while the extremity of the lower pipe, f, projecting outward through the front wall of the furnace, is adapted to be connected with a suitable supply-pipe for conveying water to the columns ofthe manifolds F.
The upright columns of the manifolds F end in the elbows j", of much smaller diameter, which connect with the horizontal upper pipes, j', the outer ends of which are closed, while their inner ends enter the steam-spaces of boilers B and B by means of elbows. These manifolds F are set between the boilers B and B", having a space between them, and stand above Athe floor of the furnace, between its front wall and the drum C.
In the space between the manifolds F is shown a box, Cr, made of plates of metal riveted together, and it is designed to be filled with any suitable non-conducting material. This boX is for the purpose of cutting oft' the radiation of heat between boilers B and B when it is not deemed expedient to use the latter. Where there is not room for the box G a single plate of iron or a brick wall may be used as a cut-oft'.
At H, Fig. 3, is shown a vertical steam-coil composed of the parallel pipes connected by return-bends h. From the tops of these return-bends spring the small elbows 7L', which bendl over the boiler B" and open into the horizontal pipe'h", which communicates with the steam-space of the boiler by means of an elbow. The rear end of t-he steam-coil H enters the drum G, while its outer end passes through the front wall of the furnace and enters the water-space of the boiler Bll through the boiler-head.
At I is shown a steam-pipe, which passes upward from the last bend of the horizontal branch coil C and enters the steam-space of boiler B".
I do not limit myself to the use of two or three boilers; but any number may be used in connection and combination with my devices.
It may be deemed necessary in some instances to support the horizontalbranch steamcoil C by means of a series of brick columns or a brick wall capped with iron and running back from the drum or bridge-wall C to the rear furnace-wall.
The lower bends of the vertical coil H may be tapped and have a pipe or series of pipes from each bend to blow out the dirt and sediment that may accumulate and settle in the bottom of the coil.
