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.BACKGROUND OF THE INVENTION1. Field of the InventionThis invention relates to testers for determining combustibility of materials. More particularly, this invention relates to devices using an injection needle, etc., to periodically blow a fine flame onto a test piece for a definite period of time, with a predetermined non-exposure period between flame exposure periods. The operation is repeated to determine the number of cycles required until the test piece begins to burn, to determine whether the test piece catches fire after being subjected to the flame for a predetermined number of cycles, or to inspect combustibility by dividing the time of residual combustion after a number, e.g., five of successive cycles of, e.g., three seconds of flame exposure and, e.g., three seconds down time by the volume lost during the operation.2. Description of the Prior ArtVarious flame tests, particularly the last above-noted test, are conducted by hand. In this case, however, human error is unavoidable and results in very poor precision. For example, if the flame was successively applied five times for three seconds each time, i.e., a total of 15 seconds, the error accumulated through human inaccuracy may result in actual flame contact time of as little as 13 seconds or as long as 18 seconds.The flame exposure period commences after the flame of the burner is brought into contact with the test piece. However, certain materials are easily affected or melted by the flame before it is actually brought to the predetermined position and wide variations in test results are obtained when testing these materials.SUMMARY OF THE INVENTIONIt is an object of the instant invention to provide a new and improved combustion testing system which minimizes error and is automated.It is a further object of the subject invention to provide an improved combustion testing system that will produce accurate results even when easily combustible material is being tested.

Two vertical supports extend between upper and lower bases, the vertical supports each having a pair of spaced parallel guide rails extending therealong, each holder having laterally projecting arm members extending from the opposite ends thereof and between the rails. A cylindrical slide member is mounted on the end of each arm member and is slidably engaged in linear sliding contact with the surface of the parallel rails on the sides thereof away from the holders. First wires are attached to the cylindrical slide members on the lower electrode holders and extend upwardly through the upper base through axial bores in the upper cylindrical slide member, and two second wires attached to the upper holders extend upwardly through the upper base. The first wires are wound in one direction around two pulleys on a horizontal shaft on the upper base and the second wires are wound in the opposite direction around other pulleys on the shaft. When the shaft is rotated in one direction the electrodes are moved toward each other and when the shaft is rotated in the opposite direction the electrodes are moved away from each other.
