DEVICE FOR DRYING EXHAUST-STEAM.

SPECIFICATION forming part of Letters Patent No. 653,334, dated July 10, 1900'.

Application filed October 19, 1899. Serial No. 734,118. (No model.)

To all whom it may concern:

Be it known that I, LEON F. N. BALDWIN, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Devices for Drying Exhaust-Steam, of which the following is a specification, reference being had therein to the accompanying drawings.

Like letters indicate like parts.

Figure 1 is a view of my invention as seen on line ,2 z of Fig. 2. Fig. 2 is a View of the same as seen on line a: a: of Fig. 1.

My invention is an apparatus for drying the exhaust-steam from the ports of the cylinder of a steam-engine, and is especially adapted for use in automobile vehicles operated by steam.

My invention consists of thecombination of a steam-boiler having hot-air fiues through it, a chamber above the boiler into which said fiues open, a vertical smoke-pipe discharging at both ends and connected with said chamber, a steam-exhaust pipe opening into said chamber, and a perforated plate extending through said chamber, with a tongue projecting into the smoke-pipe, which plate is provided with a series of angularly-inclined baffler-plates extending over the perforations of the plate, as hereinafter particularly described.

In the drawings, A represents a steam-boiler, through which pass the hot-air fines a a. These flues open through the top plate I). On the top of the boiler A is the chamber B. A steampipe 0 enters said chamber.

D is avertical smoke-pipe open at both ends and connected with the chamber B by a pipe E. A plate F is fastened to the sides of the chamber B and extends nearly horizontal, but somewhat inclined, over the top plate I) of the boiler and a short distance therefrom. This plate F has a tongue G extending on one side, which is curved at its end and extends through the pipe E and into the smoke-pipe D. The plate F has a series of perforations c 0, arranged in parallel rows, and over the rows of perforations respectively, are angularly-inclined ba'l'lier; plates 11, parallel with each other and flaring upwardly toward that end of the chamber B where the pipe 0 opens therefrom. The plates H are fastened to the plate ;F by the bolts cl d.

A damper I extends across the smoke-pipe D near its top and is pivotally hung, as shown at e in Fig. 1, through a slot on the side of said pipe. The damper I has an arm m extending outside of the pipe D, and on the end of the arm' is an adjustable Weight n.

The heat, gas, and smoke pass up through the fines aof the steam-boiler A into the chamber B and also through the perforations c c of the plate F and are deflected by the baffierplates H toward the pipe E and are carried by the pipe E into the pipe 'D, whence they are discharged into the outer air. The pipe 0 conducts exhaust-steam from the ports of the cylinder of the steam-engine into the chamber B. The plates F and H are heated by the hot air which impinges upon them from the fines (t, and this heat, together with that which passes through the perforations c c of the plate F, dries out the moisture of the exhaust-steam discharged by the pipe 0 into the chamber B, so that said steam passes out from the pipe D into the external atmosphere in the formof an invisible vapor.

The escape of dense White masses of steam directly into the open air, as is common in the use of steam-operated automobile vehicles, is a serious objection to their travel upon the streets of a city and is very liable to frighten horses, and thus to cause great damage. By the use of my said device this difficulty is avoided. p

When the fire is first started in order to make steam in the boiler A, the damper I should be open, so that the smoke will pass out through the upper end of the pipe D, and suitable means should be provided for securing the damper in such positiontemporarily, such as a hook or similar device; but when the steam has been made such fastening is loosened and the damper is thenceforth automatic. It is so Weighted that it is nearly but not quite balanced by the counterpoise n upon the arm m thereof, and normally extends horizontally across the pipe D on the open bottom thereof a suction or tendency to a vacuum is produced in the lower portions of the chamber B below the plate F and tongue G, which will draw cold air up through the fire-receptacle and the fines a, thus reducing the temperature of the chamber B,as also the steam-pressure in the boiler A. It is to obviate this tendency that the damper I is pivotally hung and weighted, as shown, for when such a condition is reached the suction downward in the pipe D at once draws the damper I down, as indicated in dotted lines in Fig. 1, and air from without rushing inthrough the top of the pipe D immediately supplies the demand, thus protecting the fire fromexcessive draft, and as soon as the pres sures are equalized the weight it brings the damper I automatically to its normal positionagain.

I claim as a novel and useful invention and desire to secure by Letters Patent- 1. The combination of a steam-boilerhavinghot-air fines through it, a chamber above the boiler into which said fines open, a pipe enteringsaid chamber and adapted to convey exhaust-steam from a receptacle containing the same, a smoke-pipe and a pipe connecting said chamber with the smoke-pipe, and a plate extending in a direction slightly inclined-from a horizontal line, through said chamber a short distance above the upper ends of said fines and located below said steam-pipe, substantially as specified.

2. The combination of a steam-boilerhaving hot-air fines through it, a chamber above the boiler into which said fines open, a pipe entering said chamber and adapted to convey exhaust-steam from a receptacle containing the same,a-smoke-pipe and a pipe connecting said chamber with the smoke-pipe, and a plate having a series of perforations and extending in a direction slightly inclined from a horizontal line through said chamber a short distance above the upper ends of said fines and located below said steam-pipe, substantially as described.

3. The combination of a steam-boiler havinghot-air fines through it, a chamber above the boiler into which said fines open, a pipe entering said chamber and adapted'to convey exhaust-steam from a receptacle containing the same, a smoke-pipe and a pipe connecting said chamber with the smoke-pipe, a plate having a series. of perforations arranged in parallel rows, which plate extends in a direction slightly inclined from a horizontal line through said chamber a short distance above the upper ends of said fines and located below said steam-pipe, and a series of angularlyinclined baffler-plates fastened to said plate and extending over the rows of perforations, respectively, substantially as shown.

4. The combination of a steam-boiler having hot-air fines through it, a chamber above the boiler into which said fines open, a pipe entering said chamber and adapted to convey exhaust-steam from a receptacle containing the same, a smoke-stack open at both ends and a pipe connecting said chamber with the smoke-pipe at a place intermediate betweenthe ends of the smoke-pipe, a plate havinga series of. perforations. arranged in parallel rows, which plate extends in a direction slightly inclined from a horizontal line through said chamber a short distance above the upper ends of said fines and located below said steam-pipe, a series of angnlarly-inclined baifier-plates fastened to saidplate and extending over the rows ofperforations, re? spectively, and acurved tongueextending from said plate through saidconnecting-pipe and down into the smoke-pipe,substantially as set forth.

5. The combination of a steam-boiler having hot-air fines through it, a chamber above the boiler into which said fines open, a pipe entering said chamber and adapted to convey exhaust-steam from a receptacle containing the same, a smoke-pipe open'at both ends and a. pipe connecting said chamber and-smokepipe at a place intermediate between the endsof the smoke-pipe, a plate havinga series of perforations arranged in parallel rows, which plate extends in a direction slightly inclined froma horizontal line through said chamber a short distance above the upper. ends of said fines and located below said steam-pipe, a

series of angnlarly-inclined baffier-plates fastened to said plate and extending over the rows of perforations, respectively, a curved tongue extending from said plate through said connecting-pipe and down into-the smoke-pipe, and a damper across the upper end of the smoke-pipe, pivotally hung. at one side of said pipe and provided with an arm LEON F. N. BALDWIN.
