Automatic coal stove stoker

A motorized coal stoker comprising:

• (a) a ramp, said ramp including a rearward plate to receive coal and a forward fire grate;
• (b) a linear reciprocating carpet overlying generally the length and width of said plate;
• and,
• (c) eccentric movement means operably connected to said carpet means, said means including:
• (i) a housing including two apertures, one aperture receiving the shaft of said motor and the other aperture receiving one end of
• (ii) a J-shaped rod, said rod's other end being operatively connected to said carpet.

In a coal stoker intended for use in a stove including an open-topped, generally funnel-shaped hopper with a lower forward passage, a rear wall and an open-topped base box forming an ash pit attached forward of and aligned with said hopper's lower forward passage, said box including sides sloping downward from said hopper's lower forward passage, said base box sides supporting thereon a ramp with corresponding sloping sides, said ramp comprising a perforated fire grate proximate the lower two-thirds of said ramp and a plate proximate the higher one-third of said ramp, said plate extending generally through said hopper's bottom, means for effecting a forced draft upwardly through said grate and a motor including a shaft operatively connected to said means for effecting said draft, the improvement comprising:

• (a) a linear reciprocating carpet operatively connected to said motor, said carpet overlying at least generally the length and width of said plate;
• (b) a transverse rearward slit located in said hopper's rear wall and aligned with said movable carpet so that said carpet, in reciprocating, extends through said rearward slit;
• (c) a plate, said plate attached perpendicular at its edge to said carpet at said carpet's rear edge and projecting downward at the rear of said hopper, said plate including an aperture;
• and,
• (d) an eccentric movement means including:
• (i) a housing including two aligned apertures, one said aperture adapted to overfit said motor shaft, said housing's second aperture adapted to receive therethrough
• (ii) a generally J-shaped rod, said rod's short leg end received by said housing's second sleeve, said rod's longer leg end being operatively connected to said carpet through said plate's aperture;
• and,
• (iii) two adjustable stops, one said stop at said rod's longer leg end and the other said stop at a predetermined point on said longer leg so that when said motor is activated by said power source, said motor shaft's 360 degree revolution causes said second sleeve to also rotate, thereby moving said rod in its stroke until said rod's stroke causes said plate to engage said stops, thereby effecting said linear reciprocating movement of said carpet while the movement of said rod between said stops causes a pause of said carpet's movement for the duration of said rod's movement, whereby coal falling on said carpet from said hopper will continually advance from said carpet's leading edge onto said perforated grate in an even flow.
