US Patent 10330322 Pellet fueled grill without cleanout port

A pellet-fired grill for barbecue cooking includes a cleanout port in the bottom of the combustion chamber and an access door so that the ash may be cleaned out and removed from the grill without necessitating disassembly of the upper components of the grill. The access door is operated by a pull link, and a stop catch mechanism adjacent to the pull link enables actuation of the pull link assembly only when the stop catch mechanism is released.
