We report radial velocities for 303 giant stars in the globular clusters M3, M13, M15, and M92. Spectra were obtained using the 4-m Mayall and 3.5-m WIYN telescopes and the Hydra fiber positioner between 1993 and 1997; most spectra were provided by the NOAO WIYN Queue Program. Typical visual magnitude values were 12 < V < 15.5. For some clusters, observations spanned times from a week to six months. The uncertainties in the velocity measurements are typically 1 km s(-1) . Several stars show velocity variations which may result from binary companions or atmospheric motions. Mean cluster velocities were measured to be -107, -120, -146, and -246 for M15, M92, M3, and M13 respectively. We anticipate the collection of follow-up observations of these candidates to further examine the probability of close companions.
