Be it known that I, Boss Winters, ot. the city of Baltimore .and 'Stato 0i Mery.- land, have invented cortein new v,enel useful improvements in en epperetus which turns to advantage the Weste steers .from the ex.- haust or eduction pipe of e :Steam-engine,

by which o blast is obtttinedtourge the tire while it et the same time heats the'` Waiter which is suppledby the torce pumps to .the

boiler.

In compartment b, Fig. 1 the4 seme steam wheel, or fan, e, er, is represented, and .0n to the lower part of its shaft, f, is also fixed. a similar, but larger, fan, 19, 9'., ,which moves in the lowermost compartment, o, Fig. .1.

The principle of creating a blast for steam boilers by propelling a fan by means ofthe exhaust steam, .was patented b y the late Phineas Davis, on the 29th July, 1834; the

- following is a general description of the apact on the fan-wheel; or all, or any part, of-

eration.

paratus for carrying his invention into op# On a shaft aboutV 8g; feet long are laced three fan-Wheels; one'near each end, or the purpose of throwing air, and one near the middle, to be propelled by the exhaust steam; this shaft is horizontal, and when used on locomotive engines is situated cross- Wise of th'ejengine; the drums inclosing the air-wheels are several inches distant from the drum inclosing the steam-wheel, land are secured in their relative positions by iron braces V'attached to each of them. The blast is varied and regulated by means of av valve situated in the steam channel leading from thecylinder to the fan, or steam wheel, and at some littledistance from the immediate jet of the steam into the drum vcontaining the steam wheel, which jet passes through an aperture of from 3 to 4 square inches, or about one half the area of the steam open ing inthe valve face of the cylindergthe remaining part of thechannel, including that where the valve for the blast is situated, has an opening equal to about 10 s nare inches. The valve is so arranged thatl a the steam may be forced through the contracted passage, just described, into the steam drum to it maybe suffered to escape byi another passage into the open air, Without acting on the wheel; byfthis means the blast is-carried. The escape, or opening, forV the passage of the steam past thevalve, always remains the same; when the opening in the direction of the fanis closed, the'opening in the direction of theopen air is increased in the same degree, the use of theV valve being only to ferre rather than obtain it by a still further contraction of the `jet passage', which Wouldreac't on the cylinders, and vbejpe'rmanently detrimental to the Working of the"` en 'ne. Again, Whenever a less blastqis required than that produced by the entire 4quantity of exhaust steam acting on the Wheel, a part of the steam being Wasted, or its action on thel Wheel lost, the remaining part' that acts on the -Wheel must necessarily e forced through a smaller passage, to produce the desired effect, (than would be the case was all thel steam to action the Wheel) and, consequently, be more detrimental to the Working of the engine. The heating the Water in its passage to the boiler byforc` ing it through a. vessel containing numerous small tubes through which the steam passes,

Vin lthe manner herein described, is also the subject of an application for a patent now ending in the Patent Oice ofthe United tates. l

The improvements contained in the apparatus first above described, which are be lieved tobe new, and for which a latent is asked, are- 1. The varying, increasing, and regulating the blast created bythe fan wheel, b v contractin or enlarging, the passage, or aperture, t rough which the steam issues on to the fan-Wheel, substantially in the manner, and4 for, the purpose, described. This expansion and contraction of the passage may be effected in various Ways besides-the one set forth. But while the same effect is obtained by analogous means, it will be manifest that the principle of my invention is'adapted.

2.1 claim the placing of the steam and fan Wheels upon an u right shaft, and thc arrangement of the dlii'erent arts in conformity therewith, as .herein described, which enables me toV combine the steam and fan Wheels in `a convenient and compact form, for the use of locomotive engines.
