Abstract
A batch charger for feeding raw batch material to a glass furnace includes a jacking assembly for raising and lowering the charger plates for improved angular adjustment thereof. The batch charger includes an adjustable charger plate crank assembly for regulating the working stroke of the charger plates and further includes adjustable batch gate assemblies for controlling the height of the raw batch blanket deposited on the charger plates. A power train is also included which permits operation of the charger by one or both of the drive motors in independent or duplex drive modes.

A batch charger for feeding raw batch material to a glass making furnace of the type having a main support frame with a raw batch hopper chute therein, and a reciprocable charger plate positioned under the hopper chute for receiving raw batch material therefrom, the improvement comprising:
- (a) jacking means positioned beneath the charger plate for independently raising and lowering front and rear ends of the charger plate;
- (b) adjustable batch gate means associated with the hopper chute including rotatable shaft means having a first end positioned at a rear face of the batch charger and operably coupled by gear means at a second end to a vertically moveable batch gate positioned at a front face of the batch charger for selectively raising and lowering said batch gate by rotative movement of the first end of the shaft means;
- and
- (c) adjustable crank means for regulating a stroke length of said reciprocal charger plate.
A batch charger for feeding raw batch material to a glass making furnace of the type having a main support frame with a raw batch hopper chute therein, and a reciprocable charger plate positioned under the hopper chute for receiving raw batch material therefrom, the improvement comprising:
- (a) a plurality of spaced-apart track means affixed to an underside of the reciprocable charger plate and extending transversely across the charger plate from a front edge to a rear edge thereof;
- (b) a plurality of spaced-apart roller sets each including a frame carrying a front and rear roller element for travel on each of said roller plate and for weight bearing support of said reciprocable charger plate;
- (c) a plurality of spaced-apart front and rear arrays of jacking means on said main support frame positioned beneath each of the roller sets, each jacking means having an extensible and retractable ram attached to the frame of the roller sets beneath the respective front and rear roller elements thereof;
- and
- (d) a pair of jacking shaft means extending from a side of said batch charger to each of said front and rear arrays of jacking means and interconnecting each of the jacking means in each respective front and rear array, whereby upon selective rotation of each of said pair of jacking shaft means, all of the rams of the jacking means in one selected front and rear array of jacking means, move simultaneously for selectively adjusting the angular inclination of said charger plate.
A batch charger for feeding raw batch material to a glass making furnace of the type having a main support frame with a raw batch hopper chute therein, and a reciprocable charger plate positioned under the hopper chute for receiving raw batch material therefrom, the improvement comprising:
- (a) a plurality of spaced-apart roller sets each including a frame carrying a front and rear roller element for travel on an underside of the reciprocable charger plate and for weight bearing support of said reciprocable charger plate;
- (b) a plurality of spaced-apart front and rear arrays of jacking means on said main support frame positioned beneath each of the roller sets each jacking means having an extensible and retractable ram attached to the frame of the roller sets beneath the respective front and rear roller elements thereof;
- and
- (c) a pair of jacking shaft means extending from a side of said batch charger to each of said front and rear arrays of jacking means and interconnecting each of the jacking means in each respective front and rear array, whereby upon selective rotation of each of said pair of jacking shaft means, all of the rams of the jacking means in one selected front and rear array of jacking means move simultaneously for selectively adjusting an angular inclination of said charger plate.
A batch charger for feeding raw batch material to a glass making furnace of the type having main support frame with a raw batch hopper chute therein and a reciprocable charger plate positioned under the hopper chute for receiving raw batch material therefrom, the improvement comprising:
- adjustable batch gate means associated with the hopper chute including rotatable shaft means having a first end positioned at a rear face of the batch charger operably coupled by gear means at a second end to a vertically moveable batch gate positioned at a front face of the batch charger for selectively raising and lowering said batch gate by rotative movement of the first end of the shaft means whereby the raw batch deposited on the charger plate from the hopper chute is selectively regulated.
A batch charger for feeding raw batch material to a glass making furnace of the type having a main support frame with a raw batch hopper chute therein, and a reciprocable charger plate positioned under the hopper chute for receiving raw batch material therefrom, the improvement comprising:
- (a) a rotatable drive shaft carrying adjustable crank means thereon, said adjustable crank means including a circular crank adjustment plate having a first bore hole therein for mounting on the drive shaft, and having a second bore hole therein spaced from said first bore hole, said crank adjustment plate further having a plurality of spaced-apart bolt holes formed around a perimeter thereof;
- (b) a crank arm rotatably affixed to a stub shaft extending from the second bore of the crank adjustment plate, said crank arm having at least one bolt hole at a first end thereof for selective register with one of the bolt holes around the perimeter of said crank adjustment plate when said crank arm is rotated on said stub shaft, at least one bolt means for passing through said registered bolt holes for securing said crank arm to said crank adjustment plate in a selected, registered position, a second end of said crank arm having a fixed shaft outwardly extending therefrom for rotatable attachment to a first end of an elongated connecting rod member, said connecting rod member having a second end pivotally attached to said reciprocable charger plate, whereby a stroke length of said connecting rod and consequent reciprocation distance of the charger plate is obtained between a minimum and a maximum value by selective register of said crank arm on said crank adjustment plate.
A batch charger for feeding raw batch material to a glass making furnace of the type having a main support frame with a raw batch hopper chute therein, and a reciprocable charger plate positioned under the hopper chute for receiving raw batch material therefrom, the improvement comprising:
- a power train comprising a pair of spaced-apart drive motors, means coupling each of the drive motors to a respective gear reducer means, a pair of axially aligned lower drive shafts, each lower drive shaft coupled to a respective gear reducer means and carrying a flanged coupling at adjacent end portions for detachably joining said lower drive shafts together, a pair of lower spur gears, each attached for rotation with a respective lower drive shaft, a pair of upper spur gears and integral upper drive shafts coupled to a respective lower spur gear, each of said upper drive shafts carrying said adjustable crank means for reciprocating said charger plates, whereby said pair of drive motors are suitable for reciprocating said charger plates by selective operation of either one of said pair of motors and by operation of both of said motors.
