摘要： A chain saw guide bar is formed of two metal plates of uniform thickness and of like size and shape. Each of the plates has local areas displaced from the plane of the plate to form protuberances on the inner face of the plate and corresponding recesses in the outer face. The protuberances are spaced from one another both laterally and longitudinally of the plate and comprise rows of protuberances which are spaced inwardly from opposite side edges of the plates a distance slightly greater than the length of the tangs of a saw chain to be used on the guide bar. The two plates are superposed on one another with the protuberances of one plate engaging matching protuberances of the other plate. One of the protuberances of each pair of matching protuberances has an integral tubular projection extending through a hole in the matching protuberance and riveted over in the corresponding recess to unite the plates in a unitary structure. The plates thus united are spaced apart from one another by the protuberances except in the local areas of the protuberances. The spacing of at least the peripheral portions of the plates outside the rows of protuberances is slightly greater than the thickness of the tangs of the saw chain so as to accommodate the tangs between the peripheral portions of the plate with working clearance. The riveting of all of the projections is preferably effected simultaneously.
