Interferometer observations are reported for radio sources in the directions of Abell clusters of galaxies. The results are presented in the form of contour maps and models of the visibility data at 2695 and 8085 MHz. Unlike 3CR radio galaxies and quasars, very few of these sources show the classical double structure. Two-thirds of the cluster sources display distortions and misalignments. In clusters with a radio source and a single dominant galaxy, the two are associated and display specific radio morphologies. Sources with intermediate angles between their twin tails point away from their respective cluster centers. The implications of these and other patterns for the characteristics of the intracluster medium and the dynamics of cluster radio sources are briefly discussed.
