ends. secured to an annulus 2l to revolve within the inner periphery of the`casing.

communicating with the'lower end of a feed chute 23 depending` from a. hopper 24,y

secured to the casing 3, or forming a part thereof A pipe 26' leading from any suitable source of compressed air supply, a blower, or the like, is fitted into the outer end of the sleeve ll to direct a blast through the space 10. Adjacent to the lower delivery end of the chute-23, the casing 3 is provided with yielding packings 25 to prevent the dropping of fuel between vthe buckets and the wall of the-chute. rlhese pac-kings 25 are preferably secured by insetting them in recesses provided for their reception in the walls of the casing, as best shown in Fig. 4.

' To prevent the pulverized fuel from dropping through the passage -10 too rapidly, its

flow is retarded by means of inclined deflecting baille plates '10s, disposed transyversely within the passage l0. Below the downwardly inclined plates 10a are provided two confronting cailles 10b projecting from vthe opposite walls of the passage, and oppositely-inclined as shownto provide a contracted throat 10c through which the passage of the fuel will be retarded as is obvious, to insure its being acted upon by the air blast.

rl`he operation of the device constructed as above described, will be'readily understood. The rotation of the motor shaft4 15 revolves the disk 12 and its sleeve vl1. and blades 2O through the worm gearing shown, and each pair of adjacent blades (Fig. 3) forni a bucket 27 to receive pulver-ized fuel from thevchute lVhen the bucket 27, by the revolution of the disk, reaches a position opposite the upper end of the passage l0, its contents drop through said opening in a fine stream, and when it reaches a point 'opposite the open ld of the passage, and the pipe 26, the air blast strikes the falling stream at the point 28, substantially midway the length of the passage 10,' and discharges it into the furnace, as will be readily understood by those skilled in the art to which the invention relates.

While the blast is ordinarily sufficient to discharge all Aof the finely-divided fuel held in suspension within the passage, any surplus particles not discharged by the blast will fall through the lower end of the passage l() and be caught by one of the buckets revolving thereunder, as will be readily understood from the illustration in Fig. 4..

It is obvious that the feeder as an entirety .is adapted to be secured to a furnace door, or in such position with relation thereto, as to make the charging of the furnace a continuous operation as long as the motor is operated.

. of radially arranged Having thus fully described my invention y and in what manner the same is designed The casing 31s provided with an openmg j for use, what l claim as new and desire to secure by Letters Patent 1s l. A. fuel feeder-comprising a stationary casing provided with a diametrically-disposed fuel passage, and a fuel inlet, a series of radially arranged revoluble 'buckets adapted to successively receive fuel throughl said inlet, means for directing a fluidiblast against 'the stream of fuel in its' travel4 through said passage, and meansl for retarding the movement of the fuel through the passage.

2. A fuel feeder comprising a stationary casing provided with a diametrically-dis posed ,fuel passage, and a fuel in1et,a series of radially-arranged revoluble buckets adapted to successively receive fuel through said inlet, means for directing a fluid blast against the stream of fuel in its travel through said passage, `and means for retarding the movement ofthe fuel through the passage consisting of obstructions arranged .therein l n 3. A fuel feeder comprising a stationary casing provided with a diametrically-disposed fuel passage, anda fuel inlet, a series adapted to successively receive fuelthrough said inlet, means for directing a fluid blast revoluble buckets Aagainst; the stream of fuel in its traveli through said passage, and' means'for retai-ding the'movement of the fuel through the passage consisting of baffles projecting from the Walls of the passage.

e. A fuel feeder comprising a stationary casing providedwith a diametrically-disposed fuel passage, and a fuel inlet, a series of radially-arranged revoluble buckets adapted toA successively receive fuel through said inlet, means for directing a fluid blast against the stream kof .fuel in its travel through said passage, and means for retarding the movement of thefuel through j the passage consisting of baille platesprojecting from the opposite walls ofthe passage, and inclined toward each other.

' 5. A fuel feeder comprising a vstationary casing provided with a diametrically-disposed fuel of radially-arranged revoluble buckets adapted to successively receive fuel through said inlet, means 'for directing a fluid blast against the stream of fuel in its travel tlurough said passage, and means for repassage, and a fuel inlet, a series' tarding the movement of the fuel through the passage consisting of inclined baille .plates projecting from the opposite walls ot the passage, and extending throughout the length of the passage.

6. A fuel feeder comprising a stationary casing provided with a diametricallydi'sposed fuel passage, and a fuel inlet, a series of radially arranged revoluble buckets senese adapted to successively" receive fuel through said inlet, ineens for directing a fluid blast against the stream of fuel in its travel through said passage, and means for retardng the movement of theiiuel through thepassage consisting of a pair of battle plates projecting from opposite Wallsnf the passage and inclining toward each other, and a second pair of bailles below the rstnamed pair, confronting each other to provide a throat through which the fuel passes.

7. In a fuel feeder, the combination with a stationary circular casing having at one side a closure disk provided with a central discharge opening, and a hollow circular casing projecting from said disk formed with a dianietricalljextending fuel passage, and at its opposite side with a. head having a hollow boss, of a disk Within said Stationary casing provided with radially-projecting blades to form fuel-receiving buckets, and with a sleeve projecting Within said boss, roller bearings between said hose and sleeve, a wor-1n Wheel mounted on said sleeve, :1 motor shaft, and a Worin therein in gear with said Worin Wheel.

8. In a fuel feeder, the combination With a stationary outer casing provided with a peripheral fuel inlet, and a hollow circular inner casing provided with a diametricallyext-ending fuel passage open at its ends, of a hopper communicating with the fuel inlet, a revoluble disk within said outer cas'- and a series of radial'blades projecting from the opposite face of the disk at the periph# ery thereoE and forming fuel-receiving buckets, and a blast said sleeve.

9. ln a fuel feeder, the combination with a circular outer casing provided with a peripheral fuel inlet, and a hollow circular inner casing provided with a diametricallyextending fuel passage open at itsr ends, of a hopper communicating with said inlet, a revoluble disk Within said outer casing having a sleeve lopen at both its ends and projecting centrally from one side thereof, a series' of radial blades projecting from the opposite side of said disk adjacent the periphery thereof and forming fuel-receiving buckets, and a blast pipe `for directing a blast through said sleeve to strike the falling stream of fuel at a point mid-Way the length of -the said fuel passage and 'dis charge it through a central opening in the casing alined with said sleeve.
