We report the discovery and spectroscopic classification of three new supernovae from PTF (ATel #1964; http://www.astro.caltech.edu/ptf ). The supernovae were discovered by Oarical, an autonomous software framework of the PTF collaboration, and by members of the PTF collaboration, based on observations made with the Palomar 48-inch Oschin Schmidt telescope. Spectroscopy was undertaken with the Double-Beam Spectrograph (DBSP; Oke \& Gunn 1982, PASP, 94, 586) on the Palomar 5-m Hale telescope on January 28 UT. The superfit (Howell et al. 2005, ApJ 634, 1190) program was used to determine the classifications. Details of the discoveries are as follows:
