T0 all whom t may concern:

Beit known that I, JOSEPH C. DILLINGHAM, of Charleston, in the county of Charleston and State of South Carolina, have invented certain new and useful Improvements in Smoke and Spark Conveyers; and I do hereby declare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in smoke and spark conveyers for locomotives, and particularly to that class of conveyers wherein the larger sparks and cinders are conducted to a point or poi-nts beneath the tender of a locomotiveandthe lighter particles and smoke to a point in rearv of the train to which the locomotiveis coupled, the object of the invention being toprovide means for retarding and collecting the cinders ejected through alocomotive smoke-stack and for conducting the smoke and finer sparks passing through said stack to the rear of a train, thus avoiding to a large extent the dirt and odor incidental to a railway trip on trains as at present equipped and reducing to a minimum the danger of accidental res from larger sparks ejected from the stack.

With these ends in view my invention consists in certain novel features of construction and combinations of parts, as will be hereinafter more fully described, and pointed out in the claims.

In the accompanying drawings, Figure l represents a side elevation of a train of cars provided with my improved smoke and spark conveyer. Fig. 2 is a view in end elevation of a locomotive-tender;` and Figs. 3, 4, 5, 6, '7, 8, and 9 are enlarged views representing in detail the construction shown in Fig. 1.

l represents the main conducting tubes or pipes, which are supported on the locomotive and tender and on each separate car, respec tively. The section of pipe over the locomotive is supported in rear of its funnel-shaped open end by the stack 2, which latter is in open communication vwith said tube or pipe, and at points adjacent to its opposite end by the brackets l3 3, supporting the ring.- clamps 4 1.,'wh'ich encircle said tube or pipe, the said brackets being secured to the roof of the locomotive-cab. The section of pipe over the tender is supported by the posts or standards 5 5 and their attached ring-clamps 4 4, while the section passing over each car rests upon the dome of the roof thereof and is firmly secured thereto in any desired manner. The respective ends of each of the main conducting pipes or tubes, with the exception of the pipe or tube carried by the locomotive,

-tion of the cars, while the short arms or members thereof are pivotally connected to a plate 13, fixed to the sloping front sections of the car-roof. The rings carried by these supporting-brackets 12 loosely embrace the iiexible tubes '7. Hence it will be apparent that the latter will be free to expand and contract throughout their entire length and to swing `laterally on curves, thus providing for-a Wide range of movement of the adjacent end of the cars. The flaring mouths 10 of these Aflexible tubes are locked together and the 1 pipes l made continuous by means of the twopart angular locking-clamp 14.. This clamp 14 consists of two semicircular angular plates, conforming in shape to the angular rib formed by the flaring mouths 10 when in their normal position, and a rod lili, extending centrally through said sections and having an eye formed at its upper outer end for its attachment to the car-roof, and screw-threads formed on its lowerprojecting end for the reception of a thumb-screw 15a, by means of Which latter the angular sections of said locking clamp are brought into engagement against the outer faces of the abutting ilaring mouths 10. It will be observed that the outer edge of each flaring mouth is provided with oppositely-located notches 11, so that when the mouths of two flexible couplings are brought together the notches of each will aline and form a pair of oppositely-disposed Acircular openings for the rod 14a, thus permitting said ilaringmouths to firmly rest against each other, thereby forming a tight joint. The rear and forward ends of the main IOO conducting-pipes carried by the locomotive and tender, respectively, arc coupled together by a single flexible tube 7 and the lockingclamp 14:, and each is provided with a depending trough 15, which troughs are in open communication with said pipes. Vithin each of the troughs is mounted a revolving screw conveyer 1G for conveying of the larger sparks passing through pipes 1 to the receptacles 17 17, located under the respective ends of the locomotive-tender,the connection between the troughs 15 and the receptacles 17 17 being effected bya series of dischargepipes 1S. By locating the screw conveyer in the manner described-that is to say, below the main condncting-pipes-a free and unobstructed passage-way is provided for the passage of the cn rrents of air entering through the funnel-shaped end of the pipe-section carried by the locomotive and likewise for the smoke, gases, and ner sparks emitted from the smoke-stack, which latter by reason of the force of said air-currents will be rapidly conveyed through the succeeding sections of the main conducting-pipe to the end of the train, from which point said smoke, gases, and finer sparks will be discharged into the outer air. The larger sparks during their passage through the main conductingpipes carried by the locomotive and tender will by reason of their weight and by their contact with the pipe, which is spirally corrugated to retard the sparks and cinders, fall within either of the troughs,from which place they will be conducted to either of the receptacles 17 by the action of the screw conveyer 16, which latter is kept continuously in motion during the running of the locomotive by means of the jointed shaft 16a, leading from one of the axles of the tender up to the rear end of the conveyer-shaft, the sections of said jointed shaft being coupled up by universal giinbal-joints.

In order to assist the passage of the smoke, gases, and finer sparks through the main conducting-pipes, or, in other words, to create a forced draft through said pipes, I may employ a blower, (not shown,) which may be located in the baggage-car or other convenient place and operated by power derived from the locomotive or from any other approved source. This blower is connected to one of the sections of the main conducting-pipe by a Y-shaped pipe 19, to one arm or member of which is pivotally connected a lever 20. The free end of the short member of this-lever is pivotally connected with one end of pitman 2l, which latter is pivotally connected at its opposite end to a depending bracket carried by a slide 22, located within said main conducting-pipe, and which is adapted to be moved back and forth to close either of the openings formed therein. By connecting the blower with the main conducting-pipe in the manner described it will be apparent that when making up a train the sliding valve 22 can readily be adjusted to cover the forward discharge from the blast-pipe, and thus direct the blast toward the rear end of the car. In addition to the blower it might also be desirable to provide the main conducting pipes or tubes carried by the cars, at points adjacent to their ends, with outwardly-projecting air ports or inlets 23, each provided at a point between its ends with a valve or swinging partition 24, which latter is adapted to be controlled from within the car by the depending rod 24N. Vhen these air ports or inlets are used to increase the draft within the main conducting-pipes, therod 2l is turned so as to bring the valve or partition 24 into a position to open the end toward the locomotive, whereby the air entering through said open front end will by reason of the position of said valve be deflected into said conducting-pipes and assist in carrying the smoke and other substances therethrough.

Vhen the air-ports are used, it will not be necessary to operate the blower, and under some conditions the use of either or both of these auxiliary means maybe dispensed with, as the draft through the pipes caused by the rapid entrance of air through the funnelshaped end of the section of pipe carried by the locomotive, due to the speed of the latter, will be sufficient to carry the smoke and gases to the end of the train.

Each of the main conducting-pipes is provided with a hinged door or doors 25 for enabling the pipes to be readily cleaned, and the doors are provided with suitable locking devices for securing them against accidental displacement when in their closed position.

The conveyer over the tender is connected to the one over the locomotive by a sleeve or jointed shaft 26, and the short arm of the forward discharge-pipe 18, which leads from the trough over the locomotive to the dischargepipe on the tender, is made flexible in order to accommodate itself to the movements of the said locomotive and tender.

Vhen the locomotive is at rest or under slow speed, a direct draft through the smokestack is necessary, and in order to arrange for same I have provided the main conducting pipe or tube, at a point directly over the open end of the'smoke-stack, with an opening 2G, adapted to be normally closed by an inwardly-swinging door 27. This door is so connected with pipe 1 that when in its elevated or locked position it closes the opening IOO IIO

2G and when in its lowest position rests in the While I have provided means for supplying additional air-blasts through the continnous iue formed by the main conductingpipes and their attached couplings, it will be seen that in trains of moderate length their use will not be required, as afair rate of speed on the part of the locomotive will be sufficient to cause a requisite amount of air to enter through the funnel-shaped mouth of the section carried by the locomotive to insure a continuous draft throughout all of said sections, whereby all smoke, gases, and finer sparks from the locomotive-stack will be rapidly conveyed to the end of the train, the larger and live sparks,by reason of their weight and form of the section and pipe carried by the locomotive and tender, being deposited within the depending trough, and from thence they will be quickly conveyed by the action of conveyers 16 to the receptacles beneath the locomotive-tender.

In order to guard'against injury to the conducting pipe, discharge pipes, and other parts carried by the locomotive-tender when the latter is being recoaled, I use a cover (not shown) which is so constructed and arranged as to completely cover all parts exposed to the fuel during the aforesaid operation.

It is evident that changes in the form and construction of the several parts might be made without avoiding my invention, and hence I would have it understood that I do not restrict myself to the particular construction and arrangement of parts shown and described; but,

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