SMOKE AND DUST ARRES'IER FOR RAILWAYS Specification of Letters Patent.

Patented Jan. 12, 1909.

Application filed October 27, 1908. Serial No. 459,796.

To all whom it may concern:

Be it known that 1, Earn V. EsTILL, a citizen of the United States, residing at Roswell, in the county of Chaves and 'lerriv tory of New Mexico, have invented certain new and useful Improvements in Smoke and Dust Arresters for Railways, of which the following is a specification.

This invention consists of novel improved means for use in connection with steam cars particularly for arresting smoke and dust. in so far as the latter mentioned purpose of the invention is concernedv the same may also be employed in connection with electric railway trains to decrease to a material extent the annoyance arising from dust and dirt drawn along by the rapid progress of the care.

For a full understanding of the invention, reference is to be had to the following detail description and the accompanying drawings, in which- Figure 1 is a side elevation showing a railway train having the invention applied thereto; Fig. 2 is an enlarged front elevation of the forward passenger car of the train showing the mounting of the hopper thereon and connections with the air pipes; Fig. 3 is an enlarged top plan View of the parts of the invention supported by the front car and showing the air pipes partly broken away; Fig. 4: is an enlarged detail view showing the connection of the draft pipe with the smoke stack of the engine; Fig. 5 is an enlarged detail view of the connections between the sections of the air pipes; and Fig. 6 is an enlarged fragmentary view bringing out more clearly the manner of connecting the air pipes with the cars of the train so as to permit of drawing dust, dirt, or foreign matter into said pipes, Fig. 7 is an enlarged sectional view on the line rom of Fig. 3 bringing out more clearly the form of the discharge opening and valve located adjacent to the branches of the air pipe.

Throughout the following detail description and on the several figures of the drawings similar parts are referred to by like reference characters.

Referring to the drawings particularly and describing the specific construction of those improvements embodying the present 1 invention, the numeral 1 indicates the cars of a railway train, the numeral 2 the engine, and the numeral 3 its tender.

In carrying out the invention it is contemplated to carry 0r convey the smoke and products of combustion. passing from the chimney of the engine 2 rearwardly there-- from and distribute the same upon the roadbed of the track over wiich the cars pass. The manner of distribution of the cinders, smoke, or other products of combustion is such as to arrest dust such as might be caused to arise from the road-bed as the rolling stock travels thereover.

As shown more clearly in Fig. l the engine 2 and its tender 3 support a longitw dinally arranged draft pipe 4, the front end of which is open as shown at 5 and at the same time formed with a downward extension 6 adapted'to receive the upper end of the smoke-stack 7 of the engine 2. Suitable supporting standards 8 are employed to support the pipe 4: and the rear end of said pipe extends downwardly as shown at 4* so as to enter a hopper 9 preferably carried by the front platform of the car 1 just in rear of the tender 3. it will therefore be seen that as the train proceeds the smoke and products of combustion are carried by the draft created through the pipe 1 to the rear end of said pipe and thence precipitated into the hopper 9. Adjacent to the hopper 9 is mounted an exhaust fan 10 and said fan is designed to force the smoke and other products of combustion, received thereby at its central portion, to an air pipe 11, branches 12 of which extend lengthwise of the cars 1 and preferably at opposite sides thereof. The pipes 12 branch from the pipe 11 at a point a short distance below the hopper 9. Near the point where the pipes 12 branch apart the bottom of the pipe 11 is formed with a discharge opening normally closed by a valve 13 adapted to be operated by handles 14 at opposite sides of said pipe 11. Should it be desired to have access to the pipe 11 at the point of branching of the pipes 12 therefrom, and for purposes of cleaning, repairing, or the like, the valve 13 may be readily opened. At intervals in their length the branch pipes 12 are formed with downwardly projecting outlet pipes 15 from which the cinders and products of combustion passing through the pipes 12 are discharged downwardly upon the road-bed be neath the cars 1 as the latter move forwardly. Necessarily the pipes 12 will be made in sections carried by each of the cars l and such sections will be joined together in any suitable way and preferably by making the rear ends 12" of the sections flexible so that the rear extremities of the pipe sections on a front car may be received by the front extremities of similar sections on .a rear car. A sort of male and female joint is provided and the flexibility of the ends of the pipe sections accommodates for ready turning of the cars as a train passes around curves in the track.

The exhaust fan 1O is operated by means of a driving connection leading from the adjacent axle 16 of the car 1. A sprocket wheel 17 on the shaft carrying the fan is connected by a sprocket chain 18 with a similar sprocket wheel 19 on the axle 16 above referred to. While the train is in motion therefore the fan 10 is operated so as to produce a forced draft through the pipes 12 whereby to convey the products of combustion along said pipes to be discharged downwardly upon the road-bed, thereby arresting the dust and providing furthermore an excellent covering for such road-bed Also located at intervals in the length of the pipes 12 are upwardly and forwardly inclined branch pipes 20 which extend through the floors of the cars 1. It is contemplated that these pipes 20 will form a means for removing dust, dirt, and other foreign matter from the cars. The draft produced in the pipes 12 will of course cause a suction tending to remove dirt and dust in the manner above mentioned.

If desired special cleaning appliances such as may be operated by exhaust air may be connected with the branch pipes 20 so that the cars 1 may be thoroughly cleaned whenever desired and convenient. The pipes 20 also afford-to a certain extent a convenient means conducive to thorough ventilation of the cars l and in this connection it may be noted that the upper ends of the pipes 20 and including a draft pipe supported by the 7 engine of the train and having its front end open, a hopper carried by the platform of a car of the train and arranged so as to receive therein the rear end of the draft pipe on the engine, a fan adjacent to said hopper and connected therewith, an air pipe leading from said fan downwardly and rearwardly, branch pipes extending from said air pipe longitudinally of the cars of the train and adjacent to opposite sides of the latter, downwardly extending discharge pipes connected with said branch pipes at intervals, and means for driving. the fan aforesaid.

2. The combination with a train, of smoke and dust arresting means such as described and including a draft pipe supported by the engine of the train and having its front end open, a hopper carried by the platform of a car of the train and arranged so as to receive thereinthe rear end of the draft pipe on the engine, a fan adjacent to said hopper and connected therewith, an air pipe leading from said fan downwardly and rear wardly, branch pipes extending from said air pipe longitudinally of the cars of the train and adjacent to opposite sides of the latter, the air pipe being formed with adischarge opening adjacent to the point where the branch pipes extend therefrom, a valve normally closin said discharge opening,- handles at opposite sides of the air pipes for operating said valve, and discharge pipes projecting downwardly from the branch pipes aforesaid and located at intervals in the length thereof. t j In testimony whereof I afiix my signature in presence of two witnesses. v L V I EMIT v.
