lll l FEED-HATER IE5:

Application filed. August 16,

To all whom it may concern Be it lrnown that I, lViriLmM T. 11; l a citizen of the United States resid Charlottesville. in the county oi .llbeznarle State of Virginia. have invented certain new an-rl useful Improve nents in Fee-dllate Heaters and Exhaust-Steam Conservers, of which the following is a specification.

T his invention ers and exhaust for an object to steam engines which shall employ the exhaust stearn to heat the feed water and the feed water to condense the exhaust steani, whereby the aqueous content of conserv d and at the same time uced into the boiler with the feed from a storage tanlr in a heated condition.

A further object of the ii vention is to provide a device erupted to be operated with a vapor engine wherein the exhaust steam presents no pressure or less than tmospheric pressure, with means for einpl ing such exhaust steam low pressure LUV the same purpose oi condensation and heat ing, as before stated.

lVith these and other objects in view the inrention comprises certain novel constructions, units, combinations of parts and arrangement of detail as will be here-i1 after more fully described and claimed.

Referring to the accompanying drawings which form a part hereoi and on which similar reference characters indicate siniilar parts,

Figure l a sectional view stantially a metrically of the cylia and on substantially a horizont g. 2 is a transverse section on line 2-2 of a vertical plane.

he devic comprises a se relates to feed water heatsteam conservers and has "ken s o- 10. l1 and f? with pistons o lo mounted in said cylinders respective.. and actuated by a common piston 1 i "6. The piston rod witl its connected pistons is driven from any approved source. As

shown in the drawings, the piston rod is extended to operate in a fourth steam cylinder 18 having a lide valve in the steamchest 19 the cylinder receiving live s n at 20 and being of conventional form. 0 "further description of the cylinder 18 and its accompanying parts is believed to be necessary to the present explanation.

The cylinder 12 and piston 15 are adapted to take water from any convenient sou cc, as the tanlr or tender of a locomotive, if the device is so employed, through the pipe 21. Valves 2:2 and 23 are employed for controlling the flow or'c' water through the chamber 2% the cylinder. Valves and 26 are also employed for controlling the flow of the water from the cylinder 12 to the chamber 27 and pipe 28.

The pipe 28 discharges into chambers 29 and 30 ly meals of two nozzles 31 (see Fig. 2), which. nozzles are conical. as indicated. and are located within conical pas sages which passages form the terminatio i of: the pipe 3%. The pipe Rel communicates with the chambers 35 and 36 controlled 31y valves 37 and 38 communicating with the cylin ler 10. Upon the opposite side of the cvlinder 10 a chamber 39 receives the ct- U steam through the pipe ll). The u from pipe 40 is controlled in its sage to the c 'nder 10 by the valves .41 and j: I so that the steam received through. the iipe i0, valves il and 42. into the cylinder 0, irrespective of its pressure, when so reeived. is compressed by the piston 19 forced through the chambers 33 andv 36. pipe 341. into the chambers 29 and 30, through and i i. One of these vaives is shown in re. ion at 2, and it is apparent that a. .l water is ejected through the nozzle 31 combines with the steam through the the combined steam and water ll raise the valve. :i screw adjusted guide positioned to limit the movement of re 4;; which similar in all respects he valve 4% ant. the not ing water and steam is also in all respects similar. both nozzles being branched from pipe 28. The guide also properly positions slide valve which in its rise and all with valve 45 opens and closes port 29 to cylinder 11. The combined water and steam. now having been introduced into the piston L. is forced through the valves 4:6 and 47. according; to the direction of 1nove rnent of the piston, into the chamber 48. From the chamber 48 the water passes through the pipe 49 and such further conle for introducnection as may be attached thereto, in heated condition, to the boiler, or to such further heating appliances, as for instance, a heating coil in the front end of a locomotive, as shall be connected therewith. The cylinder 18 when employed as a motive power for operating the several pistons 13, 1% and 15, is provided with an exhaust pipe 50, which by means of its connection at 51 with the pipe 40, also exhausts its steam into the chamber 39, so that not only does the device receive and condense the steam of the larger engine to which it is applied, but also condenses its own steam in like manner. The valves 22, 23, 25, 26, 37, 38, t1, 12 and 47 are similar in all structural particulars to the valve 46 hereinbefore described.

In operation the device actuated by the motive power shown in the drawings, would receive live steam through the port 20 actuating the piston through the manipulation of the valve 19 in substantially the usual and ordinary manner. The actuation of the piston 17 would, of course, drive the piston rod 16 and its several connected pistons 13. 14 and 15. The driving of t ie piston 15 takes water from the storage, passing it through the pipe 28 t0 cylinder 11, while at the same time steam from the exhaust or the main engine is received through pipe 40 and cylinder 10, passing through the pipe 14, commingles at the nozzles 31 and with the water from the pipe 28, and is condensed. Passing together in heated condition into the cylinder 11 such hot water is forced by the piston 13 through the chain-- ber 18 and pipe 19 to return again to its work. In this manner practically the entire exhaust steam is conserved, thereby effecting a great saving in the consumption of water and at the same time the heat oi the exhaust steam is also conserved by imparting its heat to the teed water, effecting a very great economy, both in water consumption and fuel consumption.

Having thus fully described my said in vention, what I claim as new and desire to secure by Letters Patent, is:

I 1..A feed Water heater and exhaust steam conserver comprising a cylinder and piston adapted to move water, a cylinder and piston adapted to receive and compress the exhaust steam, means to commingle the err-- haust steam and water, and a cylinder and piston adapted to force the resultant feed water to a point of further use.

2. A feed water heater and exhaust steam conserver comprising a cylinder and piston adapted to move water,a cylinder and piston adapted to receive and compress exhaust steam, a cylinder and piston adapted to receive commingled exhaust steam and water and to move it to a further point of use, nozzles positioned to commingle the water and exhaust steam, and valves positioned to control the flow of the condensed steam and water from such nozzles.

3. A feed water heater and exhaust steam conserver comprising means to move water, means to receive, compress and forward exhaust steam, means to commingle the exhaust steam and water, means to receive and forward the commingled water and steam, a steam cylinder and piston positioned to actuate the several parts, and an exhaust mechanism for the steam cylinder adapted to exhaust steam into the said exhaust steam line. I

a. A feed water heater and exhaust steam conserver comprising a water cylinder, a

steam compression cylinder, a cylinder for receiving a forwarding combined and condensed steam and water, all of said cylin ders being in axial alinen'ient, a common piston rod extending through the several cylinders, pistons mounted rigidly upon the piston rod, valves positionen to control the flow of water through the water valves positioned to control the flow or steam through the steam cylinder, valves positioned to con trol the flow of combined steam and water through the combined cylinder, and means to reciprocate the piston rod.

5. In a teed water heater and steam conserver a piston and cylinder, means to conduct water and steam commingled to the cylinder, a chamber introduced between the commingling conduit and the cylinder, a valve positioned to control the flow of commingled steam and water to the chamber and a slide valve positioned to control the flow of commingled water and steam from the chamber through a port to the cylinder.

6. In a feed water heater and exhaust steam conserver a chamber communicating with the cylinder through a port. a nozzle and passage positioned to discharge the commingled steam and water into the chamber, a valve positioned to prevent the return of steam and water from the chamber, and a slide valve operating in timed relation with the first mentioned valve adapted to close the port between the chamber and the cylinder.
