SMOKE-DISCEARGING MEANS FOR LOCOMOTIVES AND THE LIKE.

Application filed October 11 To all whom it may concern:

Be it known that l, Luowre Sononnnn, railroad engineer, a citizen. of Germany, and a resident of 23 Biinderstrasse, in the city of Herford, in /Vestialia, Germany, have invented certain new and useful Smoke-Discharging Means for Locomotives and the like, of which the following is a specification.

This invention has reference to improvements in means of discharging the smoke from locomotives or from similar coal "fed engines or moving boilers to the outside, and thereby preventing the discharge of the smoke into the sheds or enclosures in which such engines or boilers are housed, and it particularly refers to novel means of tight ening connection of the hood or similar appliance which is exchangeably mounted upon the end of the locomotive or boiler chimney, and to improved means of l12Ll1 dling and operating the same. In devices of this kind, as heretofore in use a hood, tunnel or the like is made to descend upon the upper end of the chimney of the loco motive or the like housed in a shed or the like, by means of rope, chain or the like, the hood or funnel being thereby seated upon the said chimney and causing the smoke to be discharged into the surrounding casing from which it is drawn oil into the chimney and into the atmosphere by a suitable flue or other passage. In order to prevent destruction or injuring of the locomotive or of the hood or funnel, when the locomotive is run out of the shed, it has been usual to mount the hood, tunnel or the like, so as to be capable of swinging movement in the direction of travel in addition to its vertical reciprocating movement, while the weight of said hood or the like has been balanced by a counter weight suspended from chains or ropes, and guided on rollers in the ordinary manner, a special. additional rope being employed for the raising and lowering of the hood, funnel or similar smoke escape.

This invention is intended to improve the means of suspension and the automatic return oi the said smoke escape conduits into the inoperative position, and to provide im proved means for the guiding of said conduit in the surrounding casing, and for the tightening of the joint at its points of connection with the locomotive chimney, and for the prevention of the accumulation of 1922. Serial NO. 592,440.

soot and the like and the consequent chok} ing up of the said smoke escape conduit.

With these and other objects in view only one flexible connection by rope or the like is employed for connecting the smoke conducting means with the counter weight and for the raising, lowering and rendering in operative of the said conducting means, the said flexible connection being provided with an automatically operating locking member. The casing surrounding said conducting means is laterally enlarged, and at its bottom it is provided with two substantially semi-circular flaps or lids adapted to yield upon the swinging movement of the smoke conducting means, hood, tunnel or the like, preferably only one of said lids being vertically oscillated by the swinging of the hood.

My invention will be more fully explained by the aid of the accompanying drawing showing by way of example a form of embodiment of the principles of the invention in Figure l as a side view of the entire device with connections. Figure 2 is a horizontal section through the lower portion of the tunnel or the like and through the casing on the line AB of Figure 1. Figure 3 is a fractional diagrammatic sectional view on the line C-D of Figure 2; and Figure l is a horizontal section through the counter weight and its guiding means.

The hood is funnel shaped, and consists of a tube with lower substantially spherical enlargei'uent which latter is adapted to fit upon the locomotive chimney 8. Upon its outer surface the tunnel f is provided on both sides with preferably U-shaped guides a into which studs m rigidly secured to the surrounding casing c are projectingly engaged. The casing c, as shown in Figures 1 and 2 is laterally enlarged on both sides, and as a bottom closure it is provided with two substantially semi-circularly recessed lids or flaps To the funnel-shaped casing 6 a smoke escape conduit is connected. which leads into the stationary chimney not shown. The smoke conduit may, of course, have any direction whatever. Thus, for example the said conduit may lead directly upwards into an individual smoke chimney, or into a smoke escape passage in common to a plurality of smoke discharging funnels or the like. The top portion of the funnel f is connected to a chain or rope c which is passed on guide rollers and connected to the counter Weight 0 which is vertically reciprocated in a suitable guide 9. The counter weight 0 is heavier than the funnel f, so as to retain it normally in the raised position (Figure 1). If the locomotive or the like has been run into the shed or other building containing the smoke catching and directing device, so that the locomotive chimney is placed vertically below the funnel f, the latter must be lowered upon the locomotive chimney by raising the counter weight 0. This is effected by means of a hand wheel (Z and a gear wheel connected therewith and engaging with a rack bar provided upon the counter weight. Any other lifting means may, of course, also be employed.

At the upper end of the counter weight 0 a lever a is mounted which is loaded at one side by the weight I: and is fulcrumed at the point 9. The lever a is integral with the pawl c adapted for engagement with a rigidly mounted rack bar Z). Upon raising the counter weight 0 by means of the hand wheel (Z until the funnel becomes seated upon the locomotive chimney s, the locking lever (4,2' remains at first out of engagement with the rack bar Z). But upon continuing to raise the counter weight 0 the rope or chain 'c is released from tension, and is caused to sag, and in consequence thereof the locking lever (4,6 is free to be swung laterally by the action of the one-sided load 70, and the pawl 2' may now become engaged with one of the teeth of the rack bar Z), as indicated in dotted lines. This causes the counterweight 0 to become suspended from the rack bar and thereby to be thrown out of operation. The smoke escaping from the locomotive chimney is discharged through the funnel 7 into the casing e and thence through the channel or flue 10 into the stationary chimney. If it is desired to interrupt the escape of the smoke and to disconnect the locomotive chimney from the funnel, it is only necessary to disengage the locking pawl 2' and the locking lever a; the counter weight 0 becomes then free to operate, and lifts the funnelf into its highest position.

The device is, moreover, adapted for automatic operation. Thus, if an engine is run out of the shed in the direction indicated by the arrows the chimney s will carry the funnel f with it to a certain extent, in view of the fact that the funnel is free to oscillate on the studs m, and in view of the corre sponding lateral enlargement of the casing. During this swinging movement the, lower closing flaps or lids it of the funnel casing e are swung out of the way, and during their movement any accumulated soot will be simultaneously discharged. After the engine has been run out to such a distance that it is out of engagement with the funnel f the funnel is no longer supported upon the locomotive chimney, and by its own weight it causes the tensioning of the rope or chain on which it is suspended, and in consequence thereof the locking pawl 60,2' is moved into the position of disengagement, so as to lift the pawl 2' out of the teeth of the rack bar 5. I At this moment the counter weight 0 which is heavier than the funnel will operate and raises the funnel into the inoperative position. The device according to my invention presents a great many other advantages. As a result of its mode of operation the funnel'will always be compelled to be perfectly lowered into close contact with the locomotive chimney, so as to insure the required tight connection for the exclusion of the leaking of smoke, because, unless the funnel is completely lowered, so as to raise the counter weight to the required height, the locking by the pawl lever 00,71 cannot take place, inasmuch as this locking lever can only be operated, provided the load i taken off the flexible connection between the funnel f and the counter weight 0, that is to say, when the funnel rests upon the locomotive chimney with its full weight. No similar perfect sealing of the connecting joint with the use of only one rope or flex.- ible connection, as far as I am aware, has ever been produced in the previous smoke catching and conducting means of the kind referred to.

It is obvious that my invention is capable of various modifications and alterations as the conditions of its application may require.
