Toall whom ttymay concern: y

Be it known that I, ANANIASWSMLTH, of Niagara Falls, in the county `of Niagara and State `of New York, have invented certain new i and useful Improvements in the Apparatus Used for Condensing Steam in. Steam- Engines, and that the following description, taken in connection with the;accompanying` drawings, hereinafter referred to, forms a full and" exact specication of the same, wherein I have set forth theA naturel and principles@ of my said improvements, by which my invention may be distinguished from all others of a similar class, together with such parts as I claim and `desire tohave secured to me by Letters Patent.

The figures of the accompanying plate of drawings represent my improvements. l

Figure l is a general sectional view of my improved condenser. Fig. 2 is at section taken in the plane of the line A B, Fig. l. Fig. 3 is a detail section.

The evils resulting from the use `of impure water in steam boilersare wellknown, as are `also the many unsuccessful devicesatwater, such as surface condensers, which were supposed to have accomplished the desiredresults, and to prove of great use in marine engines, as they permitted theuse of fresh water for the `boilers by iemploying the feed-water over and over again. `.Their imperfections in practice have `long been demonstrated and need not beherefenumerated. `4

The present invention accomplishes all the desirable results heretofore aimed :at in condensing apparatus, such as supplying; the boiler with pure Water, and thereby preventing the formation of scales and the deposit of impurities in the boiler-using thesame feed water over and over again-feeding the boiler with heated water and thereby making a great saving in the consumptionof fuel-fkeeping the water in the boiler always at one uniform level so as to form a perfect water-gage--preventing all back pressure of steam upon `the piston-and many other advantages which will `readily be apparent to engineers and others by inspection of the apparatus as hereinafter described and represented in the drawings.

In my new apparatus the exhaust steam is condensed in such a manner and by such a mechanical device, that a vacuum or a partial vacuumor space is formed between the For. l

A reserve Water tank may be used to supply the boiler, by means of a pump, With what small quantity of Water may be lost by leaks, &c., in thevjoints. When a supply is `not Wanted from this tank a cock shuts off its communication With the pump.

Having thus fully described my said improvement in apparatus for condensing steam, what I claim as new and useful and desire to have secured to me by Letters Patent is Y l. The employment, inV connection with a steam-engine and its boiler, of a revolving bucket Wheel arranged to receive the exhaust steam from the engine and made to rotate in a reverse direction to ,its issues in a cylinder or vessel containing Water from which the boiler of the engine is fed;

the exhaust steam being condensed by direct impingement with and adding toV said feed Water essentially as specified.

2. The combination', With the revolving bucket or Wheel constructed to receive the exhaust steam from theY engine, and cylinder or vessel containing the condensing liquid or feedwater in Which the Wheel rotates'and by direct contact With which Water the exhaust steam'is condensed in the manner described,-of a surface cooling apparatus, formed by providing said feed Water vessel with a jacket or tubes, or their equivalents, through Which a cooling liquid is made to pass or circulate free from adinixture with the Water in the vessel that directly-effects the condensation of the steam substantially as specified. f l
