UNITED STATES PATENT 'FFICEQ JOSEPH PILAUD, OF OOVINGTON, LOUISIANA.

SMOKE-CONDUCTOR.

SPECIFICATION forming part of Letters Patent No. 594,965, dated December 7, 1897.

Application filed December 1, 1896. Serial No. 614,106. (No model.)

To aZZ whom it may concern.-

Be it known that I, JOSEPH PILAUD, a oitizen of the United States, residing at Oovington, in the parish of St. Tammany and State of Louisiana, have invented certain new and railway-trains, adapted to lead the smoke from the chimney of the locomotive and carry it to the rear end of the train.

The invention consists in the features of construction hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, Figure 1 is a side elevation of a locomotive and a portion of a coach provided with this improvement. Fig. 2 is a vertical section of the same.

Referring now to said drawings, A indicates a locomotive, and B a railway-coach.

' 1 indicates the stack of the locomotive, that communicates with a pipe or passage 2. The forward end of the pipe or passage 2 has an elbow 3, provided with an opening 4 at the front end. This opening 4 is controlled bya gate-valve 5, which is opened and closed from the cab 8 of the locomotive by means of a cord 6, connected with said valve '5 and extending into the cab. The said pipe or passage 2 extends to the rear end of the 1000- motive and is provided thereat with a coupling-section hereinafter specifically described. Situated over the cab of the locomotive is a branch 7, extending from said pipe or passage 2 and provided at its upper end with a hinged cover 9. This hinged cover 9 is provided with a rod 10, that extends into the cab of the locomotive and by means of which the hinged cover can be opened or closed. The said pipe or passage 2 is provided with a valve 11 just in the rear of the branch 7. This valve 11 is controlled by a cord 12, that passes upwardly and over a pulley 13, then downwardly and into the cab 8. In this way it will be seen that the smoke can be allowed to pass out at three different points-namely,

at the front of the engine and through the opening 4, or through the branch 7, which can be controlled by the valve 13 and the valve 4 and cover 9, or the smoke can pass out at the rear end of the pipe or passage 2 by closing said valve 4 and cover 9 and opening the valve 11.

The rear end of the pipe or passage 2 is provided with a coupling-section that interfits with the coupling-section on the end of the pipe upon another car. These coupling-sections are constructed in a similar manner, so that a description of one will suffice. These coupling-sections serve to couple the pipes on the different cars automatically and to provide yielding joints that serve to maintain a tight joint between the ends of the pipes or passages during the different positions of the car in traveling. The end of the section 2 is provided with a sleeve 14, held concentric with said pipe 2 by means of a centering-ring 15 between the innerend of the sleeve 14 and the pipe 2 and held rigidly in place by means of an outer ring 16and the screws 17. The said sleeve-14 extends to about the end of the pipe 2, as shown, and situated between said pipe and sleeve is a 'sprin g 19, connected at one end to the ring. 20, that is held in place between said pipe and sleeve by screws 21. The end portion of the sleeve 14 is provided with longitudinally-extending resilient arms 22, having longitudinal slots 23 at their outer end portions. Situated between the outer end portions of the arms 22 is a sliding collar 18, having lateral projections 24, situated within said 'slots 23. The forward end of the spring 19 is connected with said collar 18, and a flexible tubing a covers said spring. The said collar 18 is provided on its outer end with a cushion or ring 25, of rubber or other material that will give the requisite cushioning effect, while the ends of the arms 22 extend beyond the ends of this collar when the latter is at the outward limit of its movement. 7

When the coupling-sections oftwo cars come in contact with each other, the cushions 25 abut, while the arms 22 on the couplingsections overlap the collars on the other sections. In this way it will be seen that in turning curves the pipe or passage is kept continuous, and, furthermore, in coupling and uncoupling the parts readily connect and disconnect without attention from the trainman. These pipes or passages are small and may be placed 011 the inside of the car, if necessary, but even when placed 011 the outside will not be unsightly or mar the appearance of the car.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a locomotive, of a pipe or passage leading from the stack thereof to the rear end of the locomotive, an opening at the forward end of said pipe or passage, a valve controlling. said opening, an upwardly-extending branch leading from said pipe or passage, a hinged cover for controlling said branch, and a valve in said pipe or passage in the rear of said branch.

2. A pipe or passage provided at its end with a sliding collar, and overlapping arms having longitudinal slots to receive pins upon said sliding collar and to which said collar is permanently fastened.

3. A pipe or passage provided at one end thereof with a concentric surrounding sleeve, a ring between said pipe and sleeve, longitudinallyextending slotted arms upon said sleeve, a sliding collar situated between said pipe and sleeve and having pins entering the slots of said arms, and springs situated between said collar and said rin In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

JOSEPH PILAUD.
