APPARATUS FOR REGENERATING EXHAUST-STEAM.

SPECIFICATION forming part of Letters Patent No. 607,582, dated July 19, 1898.

Application filed February 28, 1898. Serial No. 671,992. (No model.)

foruse in connection with stationary, marine or locomotive engines, whereby it becomes possible to revaporate and reutilize the eX- haust-steam and the heat thereof, which is now wasted, and thus render the operation of Y the engine more perfect and economical than has heretofore been possible. These objects above set forth I am enabled to attain by means of my invention, which consists in the novel details of Aconstruction and in the combination, connection, and arrangement of parts, as hereinafter more fully described, and then pointed out in the claims.

. In the accompanying drawings, forming part of this specification, wherein like letters of reference indicate like parts, Figure l is a side view of an apparatus constructed according to and embodying my invention. Fig. 2 is a top view thereof, showing the valve-operating levers in a vertical position; and Fig. 3 is an enlarged detail section of one of the valves used therein.

In said drawings, A and B designate cylinders supported in a vertical position upon a suitable base G.

D, E, F, and G denote pipes arranged in the' order named, beginning at the top, connecting the cylinders A and B, and D', E', F', and G' denote three-way valves arranged in said pipes about midway of the distance between said cylinders A and B.

II denotes the main steam-pipe leading from the boiler to the valve D' I, the main steampipe leading from the valve E' to the engine; J, the main exhaust-pipe, leading from the engine to the valve F', and K the condensation-pipe,leading from the valve G' to a steampump or other apparatus for feeding the boiler.

The stems of the valves D' E' F' G' are respectively provided with levers d e fg, and L L' denote long vertical operating-levers, the

upper ends of which are pivotally supported by bent arms M M", having their other ends pivotally secured to the tops of the cylinders A and B, and the lower ends of said levers L L' are pivotally secured to the piston-rods N N', respectively, of a duplex direct-acting steamengine O.

The ends of the valve-stein levers d and c of the valves D' and E' are connected to the long lever L, near its upper end, by links h and i and the ends of the valve-stem levers f and g of the valves F' and G' connected to the long lever L', near its lower end, by links j and 7e. v

Above the cylinders A and B is a feed-watersupply pipe P, having branches Q and Q', the ends of which are respectively connected to the tops of the cylinders A and B, and P' denotes a three-way valve located in said pipe P at the junction of the branch sections Q Q'. To the end of the stem of said valve P' issecured aleverR,having its outer end connected with the top of the long lever L by a linkA Z.

To spray the feed-Water within the cylinders A and B, the same are respectively provided with disks S S', which are suspended therein from the tops thereof by means of rods T T', respectively.

The operation is as follows: If We assume the apparatus to be in the position indicated in full lines at Fig. l, steam will be admitted to the cylinder A through the main steam-pipe I-I, valve D', pipe D, and thence pass through said cylinder A into the pipe E, valve E', and into the main steam-pipe I to the engine, the

exhaust-steam being returned through the main exhaust-pipe J, valve F', pipe F, and into theA cylinder B. At about the same time the valve P' of the feed-water-supply pipe P will be opened to admit water to the branch section Q' and cause a small quantity of Water to enter the cylinder B and fall upon the disk S' and be sprayed in said cylinder, and thereby sufficiently reduce the temperature of any live steam remaining in said cylinder, and thus facilita-te the entrance of exhaust-steam therein. The steam condensing, if there be any, Will thence be conducted from said cylinder by the pipe K and again partly fed to the boiler and the apparatus by means of a steam-pump o1' other apparatus. At this pe- Ico riod or stage of operation steamV under high the cylinder A, while exhaust-steam will be conducted from the Vengine through the-main exhaust-pipe J and into the cylinder B, the condensation, if any,vbeing conducted from theV apparatus by the condensation-pipe K. As soon as the operation above described has taken place the valves Dl and E and the valves F', G', and P will be reversed by the levers L L', operated by the piston-rods N N of the engine O, and assume the positions indicated by broken lines at Fig. l, the valve D closing a triiie in advance of the valve E. I-Iereupon steam will pass from the boiler through lthe main steam-pipe H, valve D', pipe D into the cylinder B,and there unite with and thereby regenerate the exhaust-steam therein and thence pass out of said cylinderB through Y the pipe E, valve E, and be conducted to the engineV by the Vmain steam-pipe I, the eX- haust-steam now-being returned from theVV engine through the exhaust-pipe J, valve F', pipe Rand into the cylinderA, thereon densation, if any, being, as heretofore, conductedV from the apparatus by the pipe K and recirculated. ImmediatelyV hereupon the valves will be again shifted by the operatintg-leversV L LV and the operation rst described be repeated, and so on. Y Y

It will be observed that by the use of two cylinders orV receptacles,each ofwhich Vintermittently receives steam under high and low pressure, the same alternately become the high or plus pressure and the low or VminusV pressure receptacles,V and by means ofV the valve mechanism I am enabled to normally maintain steam under high pressure intermediate the boiler and engine and steam under lower pressure (exhaust-steam) intermediate the engine and the boiler or apparatus.

It will be further observed that my apparatus is applicable to engines ot' every character, whether used for stationary, marine, or locomotive purposes, and that the valve mechanism may be operated directly by the engine or by any suitable or convenient independent mechanism.
