Patent number: 4341945Abstract: A fire extinguishing device for use with a heat fusing apparatus in an electrophotocopying machine, comprising a roller movably mounted above a copy paper conveyor associated with and located downstream of the heat fusing apparatus, means for moving the roller into rolling contact with the conveyor when an abnormality is detected in the fusing apparatus during the copying operation, and means for maintaining the roller out of rolling contact with the conveyor when no abnormality in the fusing apparatus is detected during the copying operation.Type: GrantFiled: December 31, 1979Date of Patent: July 27, 1982Assignee: Pitney Bowes Inc.Inventors: Frederick J. Pelda, Eugene A. Wirth

Patent number: 4292954Abstract: A wood burning furnace or space heater having a jacket surrounding a firebox and forming a plenum through which air to be heated is forced by a fan. There is a door in the jacket which automatically opens in the event of a failure of a fan, and thus excessively heated air is immediately released.Type: GrantFiled: May 25, 1979Date of Patent: October 6, 1981Assignee: Martin Industries, Inc.Inventor: Murray O. Wilhoite

Patent number: 4190414Abstract: A fail-safe apparatus and method for controlling the sequence of gas feed and ignition, such as by an incandescent igniter, in a gas-fired appliance, such as a thermostatically controlled timer activated clothes dryer. When the appliance is activated by the timer, the control apparatus energizes the igniter and opens a gas valve only after the igniter is energized for a period that is sufficient to heat the igniter to the temperature required to kindle the gas. If the gas is ignited, the control apparatus holds the gas valve open so that the gas continues to burn. If, however, the gas is not ignited, the control apparatus inhibits any further attempt at gas feed and ignition. If a temporary electrical power outage occurs, if the gas supply is interrupted, if the thermostat cycles on and off, or, in the case of a clothes dryer, if a loading/unloading door is opened and then shut again, the control apparatus repeats the gas feed and ignition sequence in an attempt to rekindle the gas.Type: GrantFiled: April 17, 1978Date of Patent: February 26, 1980Assignee: W. M. Cissell Manufacturing CompanyInventor: Richard A. Elmy

Patent number: 4101266Abstract: A fire prevention device for a fixing stage of an electrophotographic copying machine includes a heat shield plate movable to close the fixing stage. The heat shield plate may be controlled by a control mechanism having first and second solenoids so that the heat shield plate shuts the fixing stage only when a driving power for the copying machine is stopped or an abnormality is detected in a fixing step, during the copying operation.Type: GrantFiled: January 14, 1977Date of Patent: July 18, 1978Assignee: Tokyo Shibaura Electric Co., Ltd.Inventor: Keiichi Ishikawa

Patent number: 3967614Abstract: In an assembly of fusion furnace and fusion head for applying heat to plastic pieces to be fused, the furnace being fired with gaseous fuel fed through a conduit to a burner head in the furnace from a source of fuel, a temperature sensing probe projects into the furnace. The temperature sensing probe is operatively connected to a gas flow control device in the conduit from the source to the burner. The flow control device acts to throttle the gas flow, to maintain a predetermined variably selective temperature of the probe, from a high pressure, high rate of flow of gas to a low rate of flow of gas to the burner head. A fusion head block has a well in it to receive the temperature sensing probe when the fusion head block is in a predetermined heat-receiving position with respect to the burner head, the well being spaced from the burner head. The burner head is provided with a wire screen to ensure the maintenance of a flame at a reduced flow rate of the gaseous fuel.Type: GrantFiled: January 2, 1975Date of Patent: July 6, 1976Assignee: Emerson Electric Co.Inventor: Dale E.
