WILLIAM G. FISCHER, 0F CINCINNATI, OHIO.
FLUE-TOP.
Specification of Letters Patent. Patented lual. 11, 1919.
Application filed April 4, 1917. Serial No. 159,721.
To all whom'it may concern:
Be it known that I, W'ILLIAMG. FISCHER, a citizen of the United States of America, and a resident of Cincinnati, in the county of Hamilton and; Stateof'Ohio, have. invented a certain new and useful Improve ments in Flue-Tops, of which the following is a specification. f
This invention relates to caps or tops-for smoke-flues and, more particularly, such flues as are used on railway-cars and other moving structures or vehicles that travel at various or high speeds. In the onward movements of said traveling structures, a current of wind of greater or lessforce is produced and result's in forcing down the flue of a heater within the structure the smoke and other products p of combustion generated Within the heater, to the annoyance of those within, as .well as to the in jury or damage ofthe walls within. To remedy said evil and to produce a device that will assure the free passage of said smoke and "other gaseous products of combustion from the exit or top of the flue is the object of my. invention herein, the details of structure, as well as the mode of operation being hereinafter fully. described and then more particularly pointed out in the claims that follow. I I i In the accompanying sheet of drawings, Figure l is a fragmentary perspective view showing the upper fore-end of a traction-car having my improved flue-top in place thereon; Fig. 2, a front elevation of the flue-top taken by itself; Fig. 3, a side elevation of the said flue-top shown in Fig. 2; Fig. 4:, a central longitudinal section of the flue-top shown in normal position and as duly attached to the upper end of the smoke-flue, the latter being shown broken off; and Fig.
1 indicates the roof of a traction-car or that of any other moving structure or vehicle in connectionwith which my invention herein is particularly adapted for use and especially. because of the wind that is ordinarily forced down the flue in the advance movement of the structure and much greater when such movement is at a high speed.
2 indicates the upper end of a flue or pipe that is shown broken 05 but extending upwardly from a fuel-burning heater within the structure 3. The pipe-section 2 is a cylindrical one, as customary, and said upper end thereof projects beyond the surface of roof 1 to be telescoped by the vertical pipeseotion portion 4 of my improved cap or top. Registering holes 5 are made diametrically through the telescoped portions of theflue 2 and pipe-section 4: for accommodating a transverse wire 6, the latter being bent at its loosely supported, between its opposite ends,
on a transverse wire 11 that is similar to wire 6, the said wire 11 also having its opposite ends extending beyond the outer face of the horizontal pipe-section 8 and bent over, as shown at 12 to prevent the escape of the transverse wire 11 from bearing-support and, at the same time, permitting the valveplate 10 to be readily replaced when desired and to avoid riveting the opposite ends of said transverse wire 11.
It will be observed, in Fig. 5, that the valve-plate 10 is of egg-shape and that its cross-wire pivotal-support is somewhat above its horizontal center so as to' provide a deeper smoke-diverting portion below'the horizontal bearing in the lower portion of the pipe-section 4, sufficient surface being provided above the bearing 11 for the con tact of the wind in setting the valve-plate in position for the desired escape of the smoke and gases from the flue when the wind is coming from either side-quarter.
In practice, the cap or top is attached in position on the upper end of the flue 2 so that the horizontal section 8 lies trans: verse-to the length of the roof of the moving structure or vehicle, the opposite open ends or exit-orifices of said horizontal pipesection 8 facing said side-quarters of the wind and adapted to catch the wind from said side-quarters, especially when the moving structure is passing intersections of streets or on curves, or when the wind from said side-quarters is of greater force than that caused by the displacement of the on wardly-moving structure as it swiftly passes through the air. Thus, when a sudden gust of wind comes from a side-quarter it immediately rocks the valve-plate so that the lower portion thereof tilts toward the wind and the upper portion thereof moves with the advancing wind, thereby diverting the smoke from below into a free passage from the exit-orifice at the opposite end of the horizontal pipe-section 8 the lower portion of the valve-plate preventing any wind passing dowmvard into the flue and the crescent-shape opening now provided along the upper edge of the valve-plate, between it and the inner face of the upper arc of the said pipe-section 8, permitting the said gust of wind to freely dispel itself onward and to cause more or less of a suction to augment the flow of the smoke from said exit-orifice. To further augment the flow of the smoke from the flue-top, I provide an opening 13 in the upper portion of the valve-plate l0. Tllis hole 13 also provides means for the ordinary circulation of air therethrough when the valve-plate is in normal perpendicular position and no transverse gust of wind present in the cap or top of the smokeiiue.
15 indicates a send-circular wing or fender projecting from each of the two exitorifices or opposite open ends of the horizontal pipe-section 8 that forms the flue cap proper. These wings or fenders 15 preferably flare outwardly, trumpet-fashion, with their convex faces disposed forwardly, or toward the front of the moving structure or vehicle so that the wind is simultaneously diverted from both of said exit-orifices of the cap-proper 8 and the smoke and other gaseous products of combustion from the fire in the heater below can freely pass from said exit-orifices, without any possible chance of back-draft within the flue to cause the smoke to retreat into the interior of the moving structure or vehicle to the discomfort of those within as well as to grime or otherwise damage the inner walls or surfaces thereof.
In Fig. 3 is best shown how the opposite ends of each of the wings or fenders 15 are slightly flared at 16, such flaring 16 still further causing the wind to depart from entrance into the exit-orifices of the flue-cap 8 and successfully diverting said wind away therefrom.
To still further facilitate the free passage of the smoke from the fiue I outwardly flare the said exit-orifices of the flue-cap proper 8, as shown at 17.
It will be observed, in said. Fig. 3, also, that the opposite ends of each wing or nae'msa fender 15 are not in alinement with the perpendicular center of the flue-cap, the object thereof being to protect each upper edge of the said exit-orifices of the flue-cap as much possible against the wind that is produced by the onwardly rushing car or vehicle and especially the natural tendency of the emitting smoke or gases is to arise or ascend and to naturally overlap said upper edges of the exit-orifices to be only retreated backwardly into the flue unless the upper ends of said wings or fenders are extended. beyond the said perpendicular center of the cap. The arrangement of the other or lower ends of the wings or fenders at a point prior to reaching said perpendicular center of the flue-cap tends to divert the wind from the exit-orifices dowmvardly before it can reach said exit-orifices or their lower edges and to prevent any chance for any upward current or diversion of the wind created by the fast moving vehicle.
1. In a stationary top or cap for smokellues of vehicles, a vertical mounting pipesection, a horizontal pipe-section or capproper extending in opposite directions from the top of the said vertical mounting pipesection, semicircular substantially equal flaring wings or flanges extending from the opposite ends of said horizontal pipe-section, and a vertical valve-plate havingan opening in its upper end and pivotally supported just below said opening but centrally within said cap-proper and with its lower end of greater extended length than its said upper end whereby it projects downwardly into the said vertical pipe-section and is adapted for closing contact or engagement with the inner face thereof when swung in either direction from a normally perpendicular position.
2. In a top or cap for smoke-fines of vehicles a vertical pipe-section, a horizontal pipe-section or cap-proper surmounting said vertical pipe-section and extending in opposite directions therefrom, and semi-circular wings or fenders extending from the opposite exit-orifices or open mouths of said cap-proper with their convex faces extending in the direction of forward movement of the vehicles.
