## Abstract

A feeder of bulk materials (fuel) comprises according to the invention, a conveyor and a batcher, the case whereof is separated into at least three sections, wherein the case of the batcher incorporates drives having output shafts, each section uses a band for transferring bulk material, with bands in one section moving in opposite direction to bands in other sections, and the sections using the bands of one direction of movement are arranged alternately with the sections using the bands of opposite direction, with the drive of the sections using the bands of the same direction made common to them and furnished with output shafts coupled with shafts of the sections through clutches serving for coupling and uncoupling the drives and shafts, with the batcher case incorporating a receiver tube in the top part thereof for receiving free-flowing material, and an outlet tube in the bottom part thereof serving for delivery of bulk material from the batcher to the conveyor.

## Claims

### Claim 1

A feeder of bulk materials comprising:
a conveyor; a batcher having a case separated into at least three sections positioned above the conveyor; a band encompassed within each said section serving to transfer bulk material; shafts positioned in said sections for driving said bands; drive means for driving a shaft of one of said bands in one of said sections in a first direction and for driving shafts of bands in others of said sections in a direction opposite said first direction, with said section using said band moving in said first direction being arranged between said sections using said bands moving in the opposite direction of movement, said drive means including a common drive for all shafts of bands moving in the same direction of movement, said common drives having output shafts coupled with shafts of said sections through clutches serving for coupling and uncoupling of said drives and said shafts; receiver tube means adapted for receiving bulk material disposed in a top part of said case of said batcher and for supplying the received bulk material to said sections; and outlet tube means located in a bottom part of said case of said batcher above said conveyor so that bulk material is supplied from said batcher through said outlet tube means to said conveyor.

### Claim 2 (depends on 1)

A feeder as claimed in claim 1, wherein said bands in each said section move at different speeds.

### Claim 3 (depends on 1)

A feeder as claimed in claim 1, wherein all of said drives are coupled with all of said shafts to feed the maximum amount of bulk materials to said conveyor.

### Claim 4 (depends on 1)

A feeder as claimed in claim 1, wherein adjacent bands are simultaneously operable so as to simultaneously deliver material from two adjacent sections to said conveyor.

### Claim 5 (depends on 1)

A feeder as claimed in claim 1, wherein said bands have runs that are parallel and horizontally spaced from each other.

### Claim 6 (depends on 1)

A feeder as claimed in claim 1, wherein one of said bands has a run with a first working run inclined downwardly in the direction of movement of bulk material and having an upper portion receiving materials from said receiver tube, and a second working run extending downwardly from a lower end of said first working run to an outlet of the section containing said one of said bands.

### Claim 7 (depends on 6)

A feeder as claimed in claim 6, wherein the direction of movement of said first working run is opposite the direction of movement of said second working run.

### Claim 8 (depends on 6)

A feeder as claimed in claim 6, wherein one of said sections has a layer thickness control blade disposed therein, the blade having a lower surface positionable in spaced relationship to said first working run of said band of said one of said sections to thereby control the thickness of a layer of bulk material moved along said first working run.

### Claim 9 (depends on 1)

A feeder as claimed in claim 1, wherein said drives of said bands include shafts extending parallel to the direction of movement of bulk materials on said conveyor, the shaft of the drive for said band moving in said first direction of movement being disposed on one side of said conveyor and the shaft of the drive for said bands moving in the opposite direction of movement being disposed on a side of said conveyor opposite said one side.

### Claim 10 (depends on 1)

A feeder as claimed in claim 1, wherein the bulk materials are high-moisture clayish materials used as fuel.

### Claim 11

A feeder of bulk materials comprising:
a batcher for receiving bulk material and having a case separated into at least four sections;
a band in each section for conveying material from an upper inlet of the section to a lower outlet of the section;
independent shaft means for driving the band in each section;
first common drive means for driving selected ones of said shaft means in a first direction;
first clutch means disposed between said first drive means and each of said selected ones of said shaft means for selectively coupling and uncoupling said first drive means with each of said selected ones of said shaft means;
second common drive means for driving remaining ones of said shaft means in a direction opposite said first direction, said remaining ones alternating with said selected ones of said shaft means;
second clutch means disposed between said second drive means and each of said remaining ones of said shaft means for selectively coupling and uncoupling said second drive means with each of said remaining ones of said shaft means; and
common conveyor means disposed below the outlet of each section for conveying material away from said sections.

### Claim 12 (depends on 11)

A feeder as claimed in claim 11, wherein said inlets of said sections are disposed to receive material from a common hopper outlet.

### Claim 13 (depends on 11)

A feeder as claimed in claim 11, wherein each of said first and said second clutch means allows simultaneous coupling of one of the associated shafts and uncoupling of another of the associated shafts.
