ABSTRACT:
A flame arrester comprises a continuous flame arresting member in the form of a helix having offset interstices between adjacent turns of the helix. The flame arrester further comprises a mechanism for housing the flame arresting member. Upon installation of the flame arrester on a carburetor, air intake system, or any source of flammable gases, any backfire or flame passing through the flame arrester will be extinguished. A method for making the flame arresting member comprises the step of forming a plurality of projections in a continuous, flattened flame arresting material having a predetermined uniform curvature such that the material naturally forms a helix having a plurality of turns of a predetermined diameter, wherein a plane containing the width lies substantially perpendicular to the axis of the helix, the plurality of projections being formed such that they extend outwardly from the surface of the helix, and such that, when adjacent turns of the helix abut each other, offset interstices between the adjacent turns are formed.
