ABSTRACT:
An improvement for use in a mechanical stoker with a coal stove is disclosed. The improvement device is used with a stoker, generally including a hopper, operatively connected to a small stove having a fire box forming an ash pit. The fire box, through its sides sloping downward from the hopper, supports a ramp. The lower portion of the ramp is a perforated fire grate, while the upper portion is a plate that extends through the hopper bottom and into the stove. A fan effecting a forced draft through the grate is operatively connected to a fan motor. The improvement comprises a wiper bar which overlies generally the width of the plate. The wiper bar oscillates about the longitudinal center line of the plate to feed coal or other solid fuels from the hopper onto the grate. The oscillation of the wiper bar is effected by eccentric connection to a gear motor. When coal is fed into the hopper and the wiper bar is activated by the gear motor, the wiper bar will move in oscillation so that coal falling on the ramp from the hopper will continually advance in an even flow from the leading edge of the plate onto the grate.
