FEED-WATER HEATER.

IMPROVEMENT IN FEED-WATER HEAT ER S.
Specification forming part of Letters Patent No. 173,856, dated February 22, 1876; application filed January 4,1876.
' into which the exhaust steam discharges, lo-
cated within a larger hollow cylinder, through which the feed-water is forced into the boiler,
this steam cylinder having hollow conical studs projecting radially from its sides in all directions to the center for filling with water from the water-cylinders, and having small exit-pipes for the steam passing out lrom all parts through the water, all in-such manner that the heat is distributed and applied more efficiently within a given space than in other heaters. Outside of the water-cylinder is a jacket to receive the steam from the numerous exit-pipes, and conduct it to the dischargepipe. These two cylinders, together with the hollow water-studs and exit steam-pipes, will, in practice, be cast in one piece, so as to construct the heater cheaply, and the water-cylinderwill have a satety-valve attached, so that in case the cock between it and the boiler should be left closedwhen the pump is started up theheater will not be exploded.
Figurel is a sectional elevation of my improved heater t-a-ken on the line w w of Fig. 2. Fig. 2 is a horizontal section taken on line 22 of Fig. 2.
Similar letters of reference indicate corresponding parts.
A is the inner cylinder into which the steam is discharged from the engine-say, by pipe B. (J is the water-cylinder inclosing cylinder.
A, and having inlet and outlet pipes D E, and F is the steam-jacket surrounding the watercylinder.
The hollow conical studs G radiate from the shell of cylinder A to its center, or nearly so, and conduct the water in to the steamspace from cylinder G, so as to distribute the application of the heat very efficiently, and the distribution. Both the hollow studs and the V exit-pipes are distributed uniformly, or as nearly so asisnecessary for producing uniform eflects throughout the heater, and the capacity oi the pipes H is regulated to that of the exhaust-pipe B, so as to afford the most efficient application of the heat to the surfaces attain able without obstructing the escape of the steam.
The pipe B is prolonged a little above the bottom of cylinder A to make a kind of trap to prevent the water of condensation fromflowing back in it, and passages J are made for it to flow into steam-jacket F, from which it may be drawn by a cock, K. Cylinders A and (l are cast in connection together at L, making a substantial base, onto which the jacket F is also connected so as to seat the heater on the top of the pipe B, or any other suitable support.
The construction of the apparatus is such as to avoid all risk of fracture from expansion and contraction, the cones having been provided, instead of tubes connected at both ends, with express reference to the changes .Witnesses:
