Abstract
A scuttle device for pouring frangible, extruded wood pellets through a slot-like fill port of a hopper of a pellet-burning stove, the device having a wall formed to provide a pellet containment cavity, and having a top cap formed with an opening for filling and emptying the cavity, wherein a fine mesh sieve is supported in the cavity and is spaced from substantially the entire inner surface of the wall to provide a collection space for receiving and retaining pellet fines, and wherein a top rim of the sieve lies closely adjacent the underside of the top cap for preventing spill-over of pellets into the collection space during pouring out of the pellets.
Claims15
A scuttle device for pouring frangible fuel pellets of compacted, formed wood material into a stove hopper through a slot-like entry port, said device comprising first wall means having a first bottom wall section adapted to rest on a building floor or other base and having interconnected first opposing side wall sections and first opposing front and back wall sections extending upwardly from said bottom wall section to form the scuttle device substantially in the general exterior configuration of a coal scuttle or hod having a cavity means formed by said first wall means generally around a vertical axis, generally planar top means provided on the upper portions of said wall sections, said top means having a front portion and a rear portion lying generally coincident with said upper portions of said front and back wall sections respectively, and further having an outer periphery, shoulder means extending generally radially inwardly from said outer periphery in a first plane oriented substantially normal to said axis and radially inwardly terminating to form an access opening to said cavity means, a radially inner edge of said front portion of said top means being formed to provide pouring lip means, stop surface means provided by the underside of said shoulder means adjacent to said access opening, sieve means positioned in said cavity means and provided by second wall means of mesh material having the general configuration of said first wall means and having a second bottom wall section, second opposing side wall sections and second opposing front and back wall sections which have length, width and height dimensions less than the dimensions of the corresponding sections of said first wall means, support means contacting said sieve means and maintaining substantially the entire outer surface of said sieve means at a distance from the inner surface of said first wall means to provide a collection space for receiving and retaining fuel pellet fines, wherein said second wall means is formed to provide upper rim means on said sieve means, said rim means being adapted to lie closely adjacent said stop surface means for allowing passage of said fines into said collection space while preventing spill-over of pellets into said collection space and spill-out of pellet fines from said collection space during the pellet pouring operation, and wherein said rear portion of said top means is formed to provide a fines emptying port at the top back area of the scuttle device.
A scuttle device for pouring frangible fuel pieces into a stove hopper through a slot-like entry port, said device comprising an integral first wall having a first bottom section adapted to rest on a building floor or other base and having opposing first side sections and opposing first front and back sections extending upwardly from said first bottom section to form the scuttle device substantially in the general exterior configuration of a coal scuttle having an open top cavity formed by said first wall substantially around a vertical axis and having a top edge, a generally planar pouring cap member provided on said top edge and extending generally radially inwardly from said edge in a first plane oriented substantially normal to said axis and radially inwardly terminating to form an access opening in said cap member to said cavity, said cap member having a front portion and a rear portion substantially coincident with said first front and back sections respectively of said first wall, a radially inner edge of said front portion being formed to provide a pouring lip, a stop surface provided by the underside of said cap member adjacent to said access opening and extending around said opening, an open top sieve basket provided within said cavity and being formed by a second wall of finely perforated material, said sieve basket having length, width and height dimensions less than the dimensions of said first wall, support structure for said sieve basket and maintaining substantially the entire outer surface of said second wall at a distance from said first wall to provide a substantially continuous collection space between said sieve basket and said first wall for receiving and retaining fuel fines, and wherein said second wall is formed to provide upper rim means on said sieve basket, said rim means being adapted to lie closely adjacent said stop surface for allowing passage of said fines into said collection space while preventing spill-over of fuel pieces into said collection space and spill-out of fuel piece fines from said collection space during the fuel piece pouring operation, and wherein a rear portion of said cap member is formed to and wherein said emptying port communicates directly with said collection space but not directly with the interior of said sieve basket.
