ABSTRACT:
An automatic combustion tester is disclosed. A burner is provided and is movable by a moving means between a first position adjacent a rigidly supported test piece and a second position. The burner is connected by a first conduit to a lateral tube which is, in turn, connected to a gas bomb by a coupling means. A flame timer is used for controlling the time during which a test piece is exposed to flames from the burner during a cycle. A down-time timer is provided for controlling the time during which the flame is removed from the test piece during a cycle. A heat shield is provided along with means for moving the heat shield between a position intermediate the test piece and the adjacent bunsen burner and a position removed therefrom. First and second microswitches are positioned to contact the conduit when the burner reaches its first and second positions. The first switch controls the heat shield and the second switch is coupled to a counter means for deactivating the system after a predetermined number of cycles of operation.
