Spectral types for 45 companions to 42 variable visual double stars are presented and examined. The spectra obtained in February 1983 with the image-intensified White spectrograph attached to the No. 1 0.9-m telescope of the Kitt Peak Observatory and in July 1983 with the same instrument used with the 2.1-m telescope, are visually classified against those of standard stars for luminosity and spectral type. It is shown that the majority of the fainter companions are of late spectral types.
