In the preferred form, a self-contained heater such as a combustion operated construction heater with blower produces the heat behind the bench, and the heat is conducted through a conduit into the space beneath the bench, and then through a T-conduit in either direction to points from which it is distributed. The space beneath the bench confines the heat on the front, back, sides and bottom. Heat is distributed through openings in the top of the bench toward the back, and also through openings in the front of the bench, which may be at the top of the front of the bench and at the bottom of the bench. In a less preferred embodiment, heaters may be in spaces continuous with the bench.Type: GrantFiled: July 17, 1974Date of Patent: April 6, 1976Inventor: John F. Jenkins

Patent number: RE32026Abstract: A unified structure of a warmer is obtained by accommodating an exothermic composition consisting of iron powder, a chloride or sulfate of a metal having a tendency of ionization greater than iron, active carbon and water in a bag composed of a cloth or cloths and a film or films having aeration holes and encapsulating the resulting warmer in an air-tight envelope. Heat of oxidation of iron powder is utilized for the purpose for creating and keeping warmth.Type: GrantFiled: April 13, 1984Date of Patent: November 12, 1985Assignee: Asahi Kasei Kogyo Kabushiki KaishaInventors: Iwao Yamashita, Miyuki Shimizu
