IMPROVEMENT IN SMOKE AMD SPARK CONDUITS' FOR RAILROAD-TRAINS.

Specification forming part of Letters Patent No. 143,812; dated October 21, 1873; application filed August 2l, 1873.

To all whom 'it mag/concern:

Be it known that I, THOMAS DE Connzo, of the city, county, and State of New York, have invented a new and useful Improvement in Smoke and Spark Conduits for Railroad- Trains 5 and I doV hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings making part of this speciiication, in which Figure l is a side elevation. Fig. 2 is avertical section of the locomotive uptake and attachments. Fig. 3 is a perspective view of one of the connections, and Fig. 4 is a section and elevation of the same.

The same letters are employed in all the iig r ures in the indication of identical parts.

- acter will be particularly designated in the following specification and claims.

In the annexed drawings, A is the uptake ofthe locomotive. To this is connected a pipe, B, opening below the top of the uptake, and extending yover the locomotive, tender, and train of cars. When the pipe leads out of the uptake and over the locomotive it is at first curved upward, so as to afford an easy passage for the draft without the resistance incident to the transition of the same from a vertical to a directly horizontal direction. The pipe B is made in sections7 permanently attached to each car. It is connected by the flexible sections C C. These connections are formed by two metallic bayonet-joint pipes, C1 (l1, by which they are attached to the pipes B, connected by tubes made of aflexible mate rial, such as canvas covered by a fire-proof coating, and having within .them a coiled wire, G2, which, yielding in every direction, will permit the cars to play freely with the irregularities of the track without closing the pipes so as to interfere with the escape of the draft. In front of the uptake and opening into it is placed the funnel` formed pipe E, inclining downward in front and opening into the uptake above the level of the escape-pipe B, so that the draft of air caught by the funnel shall be directed upward :into the pipe B to prevent the reaction of the entering current against the draft ascending from the iiues of the locomotive thro-ugh the uptake. On the rear end of the pipe B may be placed an elbow, D, to give an upward direction to the products of combustion. A butteriiy-valve, F, is placed in the top of the uptake, one of the trunnions extendingthrough the uptake, and'havin g attached thereto an arm, to which is pivoted a rod, F, extending backward and within reach of the engineer. This valve should be closed when the locomotive is moving forward, and may be opened so as not to interfere with the draft when it is stationary or moving back ward.

What I claim as my invention, and desire to secure by Letters Patent, is-

l. In combination with the uptake and pipe B, a funnel-formed pipe, E, opening in front ofthe uptake, inclined and opening into the uptake above the level of :the bottom of the pipe B, substantially as set fort-h.

2. In combination with the uptake and sec tional pipe B, the connections C, formed of a flexible fire-proof casing and internal spira-l coil, C2, and connected with the pipes B by the bayonet-joint Cl, substantially as set forth.

In testimony whereof I have signed my name to this specication vin the presence of two subscribing witnesses.

THOMAS DE GODEZO.
