Roller dispenser machine

A material dispenser comprising a hopper for material to be dispensed, said hopper having a bottom opening for discharge of material therefrom, a pair of cylindrical rolls mounted in parallel relation adjacent said bottom opening, and means for counter-rotating said cylindrical rolls in a direction causing the upper surface of said cylindrical rolls to move toward each other through the material in said hopper, said cylindrical rolls containing openings which break up the material, said cylindrical rolls being made of expanded metal grid material containing said openings therein.

A material dispenser comprising a hopper for material to be dispensed, said hopper having a bottom opening for discharge of material therefrom, a pair of cylindrical rolls mounted in parallel relation adjacent said bottom opening, means for counter-rotating said cylindrical rolls in a direction causing the upper surface of said cylindrical rolls to move toward each other through the material in said hopper, said cylindrical rolls containing openings which break up the material, and deflector means within said cylindrical rolls for preventing material entering said cylindrical rolls through said openings therein from completely filling the interior of said cylindrical rolls.

A material dispenser comprising a hopper for material to be dispensed, said hopper having a bottom opening for discharge of material therefrom, a pair of cylindrical rolls mounted in parallel relation adjacent said bottom opening, means for counter-rotating said cylindrical rolls in a direction causing the upper surface of said cylindrical rolls to move toward each other through the material in said hopper, said cylindrical rolls containing openings which break up the material, a head pressure relief plate mounted within said hopper in overlying relation to a middle area between said cylindrical rolls, and means for causing limited oscillating movement of said head pressure relief plate within said hopper, said means for counter-rotating said cylindrical rolls comprising separate motor means for driving each of said cylindrical rolls, one of said motor means having two drive shafts extending in opposite directions, one of said drive shafts being connected to one of said cylindrical rolls, and the other drive shaft being connected to said head pressure relief plate for causing oscillating movements of said head pressure relief plate within said hopper.

A material dispenser comprising a hopper for material to be dispensed, said hopper having a bottom opening for discharge of material therefrom, cylindrical roll means mounted in parallel relation adjacent said bottom opening, and means for rotating said cylindrical roll means, said cylindrical roll means containing openings through which material from said hopper passes, said cylindrical roll means being made of expanded metal grid material containing said openings.

A material dispenser comprising a hopper for material to be dispensed, said hopper having a bottom opening for discharge of material therefrom, cylindrical roll means mounted in parallel relation adjacent said bottom opening, means for rotating said cylindrical roll means, said cylindrical roll means containing openings through which material from said hopper passes, and pusher means for pushing material within said cylindrical roll means out through openings in a lower surface of said cylindrical roll means.

A material dispenser comprising a hopper for material to be dispensed, said hopper having a bottom opening for discharge of material therefrom, cylindrical roll means mounted in parallel relation adjacent said bottom opening, means for rotating said cylindrical roll means, said cylindrical roll means containing openings through which material from said hopper passes, and deflector means within said cylindrical roll means for preventing material entering said cylindrical roll means through openings in an upper surface of said cylindrical roll means from completely filling the interior of said cylindrical roll means.

A material dispenser comprising a hopper for material to be dispensed, said hopper having a bottom opening for discharge of material therefrom, a pair of cylindrical rolls mounted in parallel relation adjacent said bottom opening, and means for counter-rotating said cylindrical rolls in a direction causing the upper surface of said cylindrical rolls to move toward each other through the material in said hopper, said cylindrical rolls containing openings which break up the material, said hopper including side walls having upper and lower ends, said lower ends terminating above said cylindrical rolls, said upper ends being pivotable for moving said lower ends in and out relative to each other above said cylindrical rolls while maintaining the spacing between said cylindrical rolls for decreasing and increasing the amount of surface area of said cylindrical rolls exposed to the material in said hopper.

A material dispenser comprising a hopper for material to be dispensed, said hopper having a bottom opening for discharge of material therefrom, cylindrical roll means mounted in parallel relation adjacent said bottom opening, said cylindrical roll means having a hollow interior, and means for rotating said cylindrical roll means, said cylindrical roll means having an exterior surface containing openings through which material from said hopper enters and exits said hollow interior of said cylindrical roll means.
