COAL-ECONOMY MEANS.

Specification of Letters Patent.

To all whom it may concern Be it known that we, ROBERT E. J AoKsoN and FRANK E. BELL, citizens of the United States, residing at Victoria and Norfolk, respectively, in the counties of Lunenburg and Norfolk, respectively, State of Virginia, have invented new and useful Improvements in Coal-Economy Means, of which the following is a specification.

Our present invention pertains to a more economical useof coal as a general fuel, and particularly to the use of coal asa fuel in locomotive operation; and it contemplates the provision of simple, practical and efficient means for promoting economy in the use of coal as a fuel in locomotive and other furnaces.

Other objects and practical advantages of the invention will be fully understood from the following description and claims when the same are read in connection with the drawings, accompanying and forming a part of this specification, in which:

Figuresl and 2 show the forward portion of a locomotive embodying the best practical means for carrying our invention into efiect that we have as yet devised; said views being taken at right angles to each other. Fig. 3 is a detail view, partly in side elevation, and partly in section, illustrative of those portions of our invention that are arranged adjacent to the fire box of the locomotive.

The apertures 7 extend downwardly from the rearwardly and downwardly inclined bottom wall of the smoke box, as illustrated.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

In furtherance of our invention, the boiler shell 1 that forms the smoke box contains a hopper 2, and a means 3, of conventional or one or more apertures 7 ,and in the present and preferred embodiment of our invention the said means 1s 1n the form of a casting which will be described in detail hereafter;

Located in the smoke-box and below the petticoat pipe is an exhaust steam pipe 8,

and in the lower portion of the said pipe and.

arranged over the aperture 9 that is connect- ,ed with the piston' cylinders of the locomotive is a deflector or abutment 10 which is preferably'in the form of a spoon as illus- "trated. A portion of the exhaust steam that enters the exhaust pipe is diverted from the pipe and utilized in the movement of cinders to the fire box, and this utilization of a portion of the steam from the exhaust pipe for the purpose statedis highly advantageous,

inasmuch as it obviates the necessity of making the discharge of the said pipe so small as to cause backpressure "on the pistons of the locomotive and yet does not diminish the suction capacity of the steam emitted from the pipe, to an appreciable extent,

the former is advantageous from the standpoint of economy in the operationof the lo- COII10t1V6 and the latter is important inasmuch as it assures theproper draft through the fluesiof the boiler while the pistons are in operation'and at the ,same time keeps the smoke box clear of smoke. The deflector 10 takes the portion of exhaust steam from the pipe 8 to move the cinders, and the said defiector diverts the said portion of steam into a steam conveying means 11 which is connected at 12 to a second section 13. This latter communicates with the interior of two oppositely-directed nozzles 14 which are arranged as shown in laterally directed arms 15 of the casting 6. Consequently it will be manifest that exhaust steam ejected from the. nozzles 14 will create a suction to draw the ducting means incidental to making the sharp turn from the conduits 16 to the longitudinal conduits 18 that extend rearwardly to points at the sidesof the fire-box as hereinafter described. The cavities 17 are preferably, though not necessarily, provided with removable plugs 19 through which surplus cinders may be removed at intervals,

and for the same purpose the forward end of the conduits 18. are preferably, though Patented. Oct. 3, 1916.

. the conduits 16 from wearing away the con- V not necessarily, provided with removable plugs '20. It will be noted that at point 35 in either said conveying means 16 or arms 15 that the conduit section diminishes for a small portion of its length beyond nozzles 14: so that pressures in space 36 may be increased beyond those existing in other portions of the conveying means or conduit and materials handled at this point will travel at a greater rate of speed clearing said receiving means and preventing the accumulation of said materials in the hopper 2.

The longitudinal conduits 18 have their rear ends disposed in sleeves 21 which are secured by set screws 22 on rear conduit sections 23. This provision permits of expansion and contraction due to changes in temperature, and at the same time does not interfere in any measure with the rearward passage of the cinders. At their rear ends the conduit sections 23 are provided with cinder'traps 24, preferably, though not necessarily equipped with removable plugs 25 and adapted to hold cinders with a view to preventing the cutting out of the conduit incidental to the turning of the cinders from the conduit sections 23 to conduit sections 26 which extend inwardly into the firebox 27 of the locomotive, as shown in Fig. 3. At this point it will be noticed that the conduits 26 communicate with the fire box at a point above the fire-bed and'below the baifle or buck arch 28, and from this it follows that the fire-draft in the fire box will assist in the movements of the cinders into .the fire box where the cinders will be deposited onvthe fire-bed and consumed.

In the ordinary equipment of locomotives a blower 30 is connected with the boiler and arranged to discharge between the pipe 8 and the pipe 4 with a view to keeping the smoke box clear of smoke when the locomotive is standing still or is moving without operation of its pistons. The said blower pipe 30 is provided at 31 with the conventional valve under the control of the engineer, and our present invention contemplates disposing a jet 32 from the said pipe 30 in the conduit 26 as shown in Fig. 3 with a view to giving rise to suction in either the conduits 26, 23 and 18 or draft in the fire box when the pistons are not in operation. It is to be understood, of course, that in practice we prefer to use a pipe 30 and a jet 32 complementary to each of the conduit sections 26. But said jet 32 may be located in either section 18 or 23, as well as 26 to accomplish the same purpose, this practice varying somewhat with the size and type of the locomotive.

It will be manifest from the foregoing that as the cinders fall from the deflecting means 3 they are conveyed by the hopper floor 2 to the vicinity of the aperture or apertures 7, whereupon they are drawn into the receiving means 6 by the vacuum produced therein by the discharge steam from the nozzles 14. Then after the cinders pass the nozzles ,14: they are forced by the pressure of steam from the nozzles through the conduit sections 16 and 1,8 until they reach the rear portions of the conduit sections 18 When they will be subject to the partial vacuum created in the fire box by the fire draft or by the jets 32, as the case may be, and drawn thereby into the firebox where they will be deposited and consumed by the fire.

l/Ve would have it understood in the future practice of the invention the interior fixtures of the smoke box may be variously arranged without involving departure from the scope of our invention as claimed.

Having described our invention, what we claim and desire to secure by Letters-Patent is:

' 1. The combination in a locomotive, of a fire box, a smoke box provided with a stack and a foraminous diaphragm and also provided with a downwardly and rearwardly inclined bottom wall, means connecting the portion of the smoke box at the opposite side of the diaphragm, with reference to the stack, and the fire box, an exhaust standpipe in the smoke box, a cinder receiver having openings extending downwardly from said bottom-wall and arranged for the downward passage of cinders from the smoke box at opposite sides of the longitudinal-vertical center of the smoke box, conduits for cinders connected with said receiver and extending laterally outward from the smoke box and then rearwardly and connected with the fire box, and a longitudinal central steam conduit arranged to receive steam in the stand-pipe and extending to the cinder receiver and provided in said receiver with outwardly-directed nozzles di posed in the receiving portions of the oinder conduits and below said downwardly extending openings.
