IMPROVEMENT IN FEED-WATER -HEATERS.

Simcification forming part of Letters Patent No. 178,325, dated June 6, 1876; application filed Y specification My invention has in view the production of an apparatus for the purpose of heating the feed-water of boilers by the exhaust steam of an engine; and consists in heating the said water by passing it in thin sheets between two.

metallic plates, a series ot' which, provided with proper openings Yand connections for the circulation of the water, are connected togetherand placed within a cylindrical jacketed chamber, into which the exhaust steam is introduced for the purpose ot' heating the exterior surface of these plates, in the manner hereinafter described. 1

The water is rst introduced into the jacket of said cylinder before entering the series ot' plates for the purpose of absorbing what heat is produced by the exhaust steam against the interior surface of said cylinder, thereby utilizing what heat might have been produced and lost by the radiation of the exterior sur- .'face of a single cylinder, which arrangement,

when complete, will prove both effective in operation and cheap in construction.

.Figure 1 is a sectional elevation through Fig. 3 at a point corresponding with the section-line of the latter, A BK1 D, showing the manner' in which the lmetallic plates aresecured together and into the-jacketed cylinder; also, in part, the water-connections between said plates, connections J J2 between jacket and plates, inlet and outlet pipe LL2; also, the manner in which the exhaust steam enters the lower nozzle H of jacketed cylinder E F, strikes the lower plate of the lower section G3, passing around the circumference B2,

infbetween the last-mentioned and next plate,

and so on through delivery-nozzle I,7 provided with a valve.

'Fig 2 isa sectional elevation through Fig. 3, at a point corresponding with the sectional line in the latter, B K2 C, showing more particularly the alternate water-connections between the plates, (not shown in Fig. 1;) also showing the connections J8 between the last November 20, 1875: I

plate G3 of the series and thejbottom space bi, connecting with the delivery-nozzle L2.

Fig. 3 is a sectional plan taken through line A D ot'Fig. l, and B G ot' Fig. 2, showing the position ot' the three bolts K1K2 K3, which bolt 'together the series otL plates and secure the same within the jacketed cylinder' E F;

also represents the division-piece g in the plate,

foi` the purpose of reversing and causing the water to move around in the space formed by the two plates, as represented by the arrows Yfrornthe inlet and outlet nozzles.

on' the left-hand side 5) from thence into the space b5 to the left, and up in a like manner into space b4, and so on until the water arrives to b, from which it passes into and through the connections J J2, and into the first section Grl by connectingnozzle J 3, Fig. 1 from thence passes in between the two metallic plates, from J3, Fig. 1, to J", Fig. 2, (in an opposite direction to that as represented by the arrows passing from J9 to J6, Fig. 3,) from J"I into section G2, Fig. 2, moving in an opposite direction from the latter, and as represented bythe arrows in Fig. 3, which is a plauof that particular section; and from thence to the nozzle communicating with the next section, and so on until arriving to the last section G3, Fig. l, which delivers through nozzle J8, Fig. 2, into the space 117, formed by the lower portion ot' the internal cylinder and bottom plate M', to which the outlet-pipe L2 is attached, and from which the hot water heated bythe passage of the exhaust steam through the jacketedcylinder, in the manner hereinafter described, passes to the force-pump or boiler direct.

The steam enters the nozzle H at the bottom of the jacketed cylinder E F, Fig. 1,

strikes the lower plate ofthe section G3, passes around its circumference B2,at the same time heating the interior portion of cylinder F at space b6,passing in between the last-mentioned section and the next, through thecenter Bof this last, in between this and the next, around the circumference of this last,'and so on until the exhaust steam reaches the upper portion of the heater, when then the steam passes ofi' through the nozzle I, providedwith-avalve, as shown, Fig. 1, to regulate the density of the steam, if so desired.

Having explained the object, construction,

and operation of my invention, what I claim'- A jacketed cylinder, E'F, With top amibottom plates M M', provided with inletr stearnnozzle H and outlet-nozzle I, arranged Wit/liav HENRY A. PHILP.
