Vacuum cosmological models in the simple formulation of scale-invariant theory proposed by P. S. Wesson [1] with a gauge function $\beta(x)$ are obtained through the solutions of the field equations for three different, cases when the space time is described by Bianchi type-I metric. Some physical properties of the models are also discussed.
