SMOKE AND CINDER DEFLECTOR FOR CARS.

EPECIFICATIOII forming part of Letters Patent No. 350,888, dated October l2, 1886.

Afplieation filed April 15, 1886. Serial No. 198,906. (No model.)

To @ZZ whom it may concern:

Be it known that I, GHARLEs T. LUTHY, of I Peoria, in the county of Peoria, State of Illinois, have invented an Improved Smoke and Cinder Detlector for Cars; and I do hereby declare that the following` is a full, clear, and eX- f act description thereof.

The object of thisinvention is the construction of a simpler and more effective means for keeping away from the passenger-cars of a railw( y-train the smoke and cinders issuing from the smoke-stack of the engine. thereof.

I have discovered by observation and experiment that a moving train carries with it an enveloping air shaft ofsome few feetin thickness. In addition to this motion of the air there are many transverse currents and eddies, which tend to suck in against the sides of the cars whatever smoke, soot, or cinders come into the outer portions of the air shaft. Although this air envelope may not move with the saine velocity as the train, it still keeps with the saine sufficiently to permit the smoke and cinders carried thereby to enter every aperture which there may be in the sides or ends of the cars; hence it becomes extremely difficult to ventilate the cars without permitting the entrance of the disagreeable products of combustion. In case there is a very strong lateral wind the smoke and cinders may be carried quickly enough to one side to keep them from beinginuenced by the moving air envelope, and thereby dashed against and into the cars; but with simply a light wind or a parallel breeze there is no relief'.

To keep the smoke and other products of combustion issuing` from the engines smokestack from coming under the intluence of the before-described movingair envelope, I have invented the smokedetleeting conduit, attached to the smoke-stack and adapted to convey the combustion products therefrom to the leeward of the engine and outside of all possibility of contact with the said air envelope.

In the drawings which form a part of this erence refer to like parts, Figure l represents a perspective view of an engine smoke-stack having my detlector connected thereto. Fig. 2 is a diagram representing a train, the delector, and air envelope.

Referring to the drawings, B is the locomotive, S, the smoke-stack. The dotted lines U are the borders of the air envelope. V is the smoke, A the detlector, and B is the hood connecting said deliector to the smoke-stack. The hood B, I usually secure to the smoke-stack above and to the rear of the same, and have it somewhat funnelshaped or conical, with the larger month forward. To the rear and smaller end of the hood B is hinged, pivoted, or otherwise loosely secured the detlector-eonduit A, which may be of uniform diameter or slightly tapering toward its free end. This detlectorconduit may be adapted to swing about its loose attaching-point in either a horizontal plane or one more or less vertical. All that is necessary is to have the free end of the deiector capable of directing a current passing through it obliquely upward or to either side of the engine, and to asuficient distance therefrom to send it free oi' the air envelope aforesaid.

The means which I have adopted, and show in the drawings, for shifting the deliector-conduit to enable it to discharge to leeward consists in forming the inner end of the deflector A with an elbow, swiveling this elbow A to the rear of the hood, and rigidly connecting said deflector with the rock-shaft C, which, running back into the cab of the engine, and being provided with the operating-lever Dand a lock, E, enables the engineer to shift the delector and secure it in the desired position.

In use, the train traveling at a good speed, the engineer notices if there is any transverse motion of the wind, or if the same blows in a direction parallel to the track, and accordingly shifts the detlector to point obliquely to one side away from the wind or upward. As the train rushes forward, the air enters the hood B with a corresponding velocity, is given an increased relative motion by the tapering form ofthe hood, and passes on through the conduit A, bearing the smoke, soot, and cinders with it. Vhen this 'air and its contents reach the end of the detlector-conduit, there is given thereto a sufficient oblique throw to send the same entirely outside of the influence of the following air envelope, and hence the windows of the train canbe left wide open without danger of the entrance of the smoke and cinders. If the train passes about a decided curve, or the wind changes, the deliector can be changed to suit the new conditions. rIhe conduit may not be entirely tubular, but maybe open laterally more or less. The tubular form, however, I deem preferable. y

WhatI claim as myinvention, and fo'rwhich I desire Letters Patent, is as follows, to wit:

1. The combination, with the smokestack, of the loosely-held deflector and means for shifting the same, whereby the smoke and other products of combustion issuing from said smoke-stack .are forced by the counter-current of air to either side of the engine and outside of the influence of the accompanying air envelope.

2. The combinatiomwith the locomotive-engine and its smoke-stack, of'the hood fixed to said stack, the deector-conduit loosely connected to said hood, and means for shifting said deflecto'r-conduit, for the purpose set forth.

3. Thecombination,withthelocomotve-engine and itssmoke-stack, of the hood fixed to the smoke-stack, the defiector-conduit swiveled to the rear end of said hood, the rockershaft rigidly connected to said dellcctor-conduit, and the lever for operating said shaft and conduit.

4. The combinatiomwth the locomotive-engine and its smoke-stack, of the tapering hood B, fixed to said stack, partly over and to the rear thereof, the delectorcond uit loosely at- "tatdto said hood and projecting obliquely therefrom, and means for shifting said deliector-conduit, for the purpose specified.

5. The combination, With a locomotivevengine and its smoke-stack, ofthe hood B, Xed to the smoke-stack, the detlector-conduit A, swiveled to said hood, therock-shaft C, rigidly connected to said conduitand extending rear- Wardly therefrom, the operating-lever D on said shaft, and the lock E, for holding the le ver, shaft, and conduit in a desired position, substantially as set forth. In testimony that I claim the foregoing invention I have hereunto set my hand this 12th day of April, in the year 1886.
