Abstract
Abstract A drive and mounting mechanism for a rotatable and angularly adjustable charge distribution device mounted in the throat of a blast furnace is disclosed. The drive mechanism includes a rotary disc mounted concentrically with the tubular feed spout through which charge material is delivered to the distribution device, the distribution device being suspended from the underside of the rotary disc, and a ring gear rotatably supported on the upper side of the disc and movable independently thereof. A drive shaft coupled to the ring gear passes through the rotary disc and is connected to means for selectively varying the inclination of the distribution device. The drive mechanism also includes means for rotating the disc and gear and for varying the speed ratio therebetween to thereby drive the inclination adjustment means drive shaft.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
118 words
Drive means for a rotatable and simultaneously angularly adjustable movable member comprising: a rotary disc; means mounting said movable member from the underside of said disc; ring gear means supported on the upper side of said disc for rotation therewith, said gear means being rotatable independently of the rotation of said disc; output shaft means driven by said ring gear means, said output shaft means including an output shaft which passes through said disc and is rotatably mounted therein; means for angularly displacing said movable member independently of the rotation thereof, said angular displacement providing means being coupled to said output shaft means; and drive means for rotating said disc and ring gear means independently of one another.
Claim 2
Dependent Claim
118 words
Drive means for a rotatable and simultaneously angularly adjustable movable member comprising: a rotary disc; means mounting said movable member from the underside of said disc; ring gear means supported on the upper side of said disc for rotation therewith, said gear means being rotatable independently of the rotation of said disc; output shaft means driven by said ring gear means, said output shaft means including an output shaft which passes through said disc and is rotatably mounted therein; means for angularly displacing said movable member independently of the rotation thereof, said angular displacement providing means being coupled to said output shaft means; and drive means for rotating said disc and ring gear means independently of one another.
Claim 3
Dependent Claim
52 words
The apparatus of claim 1 wherein said rotatable and angularly adjustable member is a material distribution device mounted within a shaft furnace and wherein said rotary disc and ring gear means are positioned about and concentric with tubular means for delivering material from the exterior of the furnace to said distribution device.
Claim 4
Dependent Claim
44 words
The apparatus of claim 2 wherein said drive means comprises: a main drive motor having a rotary output shaft; means for coupling said main drive motor output shaft to said rotary disc; and pitch angle adjustment drive means coupled to said ring gear means.
Claim 5
Dependent Claim
106 words
The apparatus of claim 3 wherein said pitch angle adjustment drive means comprises: an auxiliary drive motor having a rotatable output shaft; planetary gear means including a planet gear, an inner gear and intermediate gear means; means coupling said planetary gear means planet gear to said main drive motor output shaft; means coupling said planetary gear means inner gear to said auxiliary drive motor output shaft; and means coupling said planetary gear means intermediate gear means to said ring gear means whereby the speed ratio between said disc and ring gear means may be varied to thereby cause rotation of said output shaft means output shaft.
Claim 6
Dependent Claim
82 words
The apparatus of claim 3 wherein said means for coupling said main drive motor output shaft to said rotary disc includes: a rotary sleeve concentric with the tubular material delivering means, said rotary sleeve being affixed adjacent one end thereof to said rotary disc; a drive gear affixed to the exterior of said rotary sleeve at a point displaced from said rotary disc; means coupling said main drive motor output shaft to said gear affixed to the exterior of said rotary sleeve.
Claim 7
Dependent Claim
82 words
The apparatus of claim 4 wherein said means for coupling said main drive motor output shaft to said rotary disc includes: a rotary sleeve concentric with the tubular material delivering means, said rotary sleeve being affixed adjacent one end thereof to said rotary disc; a drive gear affixed to the exterior of said rotary sleeve at a point displaced from said rotary disc; means coupling said main drive motor output shaft to said gear affixed to the exterior of said rotary sleeve.
Claim 8
Dependent Claim
31 words
The apparatus of claim 6 further comprising: bearing means supporting said ring gear means on said rotatable disc, said bearing means also coupling said ring gear means to said rotary sleeve.
Claim 9
Dependent Claim
90 words
The apparatus of claim 2 wherein said mounting means for said distribution device comprises: means rotatably supporting the distribution device at a first point adjacent a first end thereof; regulating arm means supporting said distributing device at said first end thereof in a region substantially oppositely disposed to said first point; and means coupling said regulating arm means to said output shaft means whereby rotation of said output shaft means will cause rotation of said regulating arm means about an axis transverse to the axis of said output shaft means.
Claim 10
Dependent Claim
53 words
The apparatus of claim 8 wherein said regulating arm means comprises: a pair of displaced shafts extending from said distribution device; an elongated arm having recesses therein for receiving said shafts; a rotatable axle extending transversely from said elongated arm, said transverse axle extension being rotatable and being connected to said coupling means.
Claim 11
Dependent Claim
90 words
The apparatus of claim 7 wherein said mounting means for said distribution device comprises: means rotatably supporting the distribution device at a first point adjacent a first end thereof; regulating arm means supporting said distributing device at said first end thereof in a region substantially oppositely disposed to said first point; and means coupling said regulating arm means to said output shaft means whereby rotation of said output shaft means will cause rotation of said regulating arm means about an axis transverse to the axis of said output shaft means.
Claim 12
Dependent Claim
53 words
The apparatus of claim 10 wherein said regulating arm means comprises: a pair of displaced shafts extending from said distribution device; an elongated arm having recesses therein for receiving said shafts; a rotatable axle extending transversely from said elongated arm, said transverse axle extension being rotatable and being connected to said coupling means.
