Horizon eclipse pellet stove damper controls
In the device of each of those patents, a piston is reciprocated horizontally below the bottom outlet opening of a hopper to move pelletized fuel from the hopper along a feed cylinder or trough. Another type of positive feed system is shown in U.S. Known systems use augers or screw conveyors which pulverize some of the fuel pellets and which can become jammed. In a positive feed system, the fuel is forcefully moved to the firebox. Preferably such stoves are self-feeding for an extended period, such as several hours. In known pellet stoves mechanism is provided for automatically feeding pelletized fuel to the firebox at approximately a uniform, sometimes adjustable, rate. The present invention relates to fuel feed mechanism for feeding pelletized fuel from a hopper to the firebox of a stove. The mechanism defined in claim 9, in which the gate member is biased to an upright position by gravity for engagement against the forward end of the feed plate when the plate is in its forward position. The mechanism defined in claim 1, in which the gate member is swingably mounted on the feed trough.ġ0. The mechanism defined in claim 7, in which the resilient member is a tightly coiled helical spring.ĩ.
The mechanism defined in claim 1, including a resilient member extending across the feed trough in the area of the hopper outlet opening and above the feed plate to prevent pellets from becoming jammed at the hopper outlet opening.Ĩ. The mechanism defined in claim 5, in which the sensing means includes a limit switch and a timer circuit triggered when the feed plate reaches its forward position.ħ. The mechanism defined in claim 3, in which the reciprocating means includes a motor for moving the feed plate and means for sensing the position of the feed plate and controlling the member.Ħ.
The mechanism defined in claim 3, including means for adjusting the length of the predetermined delay period.ĥ.
The mechanism defined in claim 2, in which the reciprocating means includes means for automatically maintaining the feed plate in its normal forward position for a predetermined delay period between movements of the feed plate to its rearward position and back to its forward position.Ĥ. The mechanism defined in claim 1, in which the reciprocating means includes means for normally maintaining the feed plate in its forward position for normally closing the feed trough and hopper from the firebox.ģ. Mechanism for feeding fuel pellets to a firebox comprising a pellet hopper having a bottom outlet opening, a feed trough extending generally horizontally from below said hopper outlet opening and having a forward end portion adjacent to the firebox, a feed plate mounted in said trough below said hopper outlet opening such that pellets from said hopper are supported on said feed plate, means for reciprocating said feed plate in said trough between a rearward position adjacent to said hopper and a forward position adjacent to the firebox for advancing feed pellets along said trough from the hopper toward said firebox, a gate member mounted adjacent to said forward end portion of said feed trough and positioned such that said feed plate engages said gate member when said feed plate is in its forward position and closes said feed trough and said hopper from the firebox when said plate is in such position, and said feed plate discharging the pellets through a gap between said gate member and said forward end portion of said feed trough when said feed plate is moved from its forward position to its rearward position.Ģ.
