We have searched for the production of free Q = +-1/3e, Q = +-2/3e and Q = +-4/3e particles produced in e/sup +/e/sup -/ collisions at a center-of-mass energy of 29 GeV in 77 pb/sup -1/ of data collected by the time projection chamber at PEP. No evidence has been found for the production of these particles. Upper limits are established on the inclusive cross section for the production of Q = +-1/3e, Q = +-2/3e, and Q = +-4/3e particles in the mass range 1.0 to 13 GeV/c/sup 2/, improving upon previously established limits. 58 references.
