My invention relates to a smoke deflector" andhas particular referionce-to a smoke de-" flectol' for application to a railway locomo' tive by means'of Whichthe air is deflected 5 above the stack causingthe'smoke to rise abovethe locomotive and out of thevlew of the enginemen, and also above the train without entering the coaches and causing disoom'fo'rt to the passengers" and also pre vents the gas from oil burning locomotives from entering the coaches.

As the rate of speed of the locomotive increases the suction also increases, resulting in the carrying of the smoke upward to a considerable height and out of the faces of the enginemen and also to such a height that the smoke does not enter the railway cars. As long as the speed of the train is continued to twenty miles an hour the upper member remains in a vertical position and when the speed decreases below twenty miles an hour, the air current is not sufiicient to lift the upper hinged member into vertical position and it falls into a horizontal position as shown in Figure 3, thereby allowing the locomotive to enter depots having smoke jacks and the like, which ordinarily are fairly close to the upper end of the stack and allows suflicient clearance for the locomotive to pass thereunder without tearing away the smoke deflector. These stations where smoke jacks are employed are nearly always closed at one end. Therefore, there is little likelihood of a locomotive encountering a head wind when entering the station, so that the deflector is not lifted, thereby running no danger of catching the deflector against the smoke jacks. And contrary, if a wind of high velocity is traveling in the same direction as the train is moving, the device will remain in horizontal position for a longer time than if the train were moving in the opposite direction to the direction of travel of the wind, but in this case the smoke will be blown upward and carried with the train so as to not interfere with the view of the engine crew or obstruct their view of signals and the like, which is a common happening in the present type of extremely long boilers used in railway service.
While I have described more or less precisely the details of construction, I do not wish to be understood as limiting myself thereto, as I contemplate changes in form and the proportion of parts and the substitution of equivalents as circumstances may suggest or render expedient without departing from the spirit or scope of my invention.
I claim: I
1. A smoke deflector comprising in combination, a stationary plate and means for securing the plate to a locomotive in front of the smoke stack, the said member having wings formed at each side thereof whereby a channel is formed at the front of the smoke deflector.
2. A smoke deflector comprising in combination, a stationary mem er of approximately the same height as a locomotive stack, means for securing the plate to the smoke box of a locomotive in the front of the smoke stack, and means at the side of the said plate for preventing the air traveling around the sides of the said vertical plate. I
3.. A smoke deflector comprising in com- .bination, a stationary member, means for securing the member to a smoke box in front of the locomotive, and a member secured in hinged relation to said first mentioned mem her.
4-. A smoke deflector comprising in combination, a stationary member, means for securing the member to a smoke box in front of the locomotive, and a member secured in hinged relation to said first mentioned mem her, the said hinged member extending above the stack.
5. A smoke reflector comprising in combination, a stationary member, means for securing the member to the smoke box of the locomotive, a member secured in hinged re lation to said first mentioned member, and a hinged member comprising a vertical portion and a wing portion at each of the sides of the said hinged portion.
6. A smoke deflector comprising in comination, a stationary member having wings at the sides thereof, means for securing the member to a locomotive, a member secured in hinged relation to said first mentioned memher, the saidhinged member comprising a vertical portion and a wing portion at each of the sides thereof, the said hinged member being normally held in inclined position.
7 A smoke deflector comprising in combination, a plate, means for mounting the plate in front of a locomotive smoke stack and a second member hinged to said plate adapted to extend above the stack when in vertical position.
8. A smoke deflector comprising in combination, a plate, means whereby the said plate is secured to a locomotive in front of the smoke stack, and a second member pivotally secured to said plate intermediate its ends, adapted to extend above the said stack when in vertical position.
9. A smoke deflector comprising in combination, a member mounted in front of a locomotive smoke stack, and a member pivot ally secured thereto and adapted to be raised into vertical position by air resistance created by the forward movement of the 10- comotive.
