The Pati-Salam model for unified lepton-hadron symmetry is extended to incorporate SU(2l)/subL/ x SU(2l)/subR/ x SU(4) gauge symmetry in order to include models containing 4, 6, or more fractionally charged quarks. A symmetry-breaking scheme for the SU(2)/subL/ x SU(2)/subR/ x SU(4) subgroup containing all known interactions is developed for arbitrary values of l. The symmetry-breaking procedure leads to the Weinberg theory of weak interactions in a natural way. The Weinberg angle is expressed in terms of the coupling constants and dimensionality l of the theory. Implications of embedding the SU(2l)/subL/ x SU(2l)/subR/ x SU(4) group in a universal gauge group are discussed. In such a model sin/sup 2/theta/subW/ = 3/8 independent of l. (AIP)
