The excellent book Sailplanes 1920 - 1945 by Martin Simons includes an excellent write-up, a photo and scale drawings of this glider.  A quote from the book, "An influential article in the November Aero Digest by A P Artran, President of the Franklin Glider Corporation, set out the arguments an announced the development of a new glider, intended for basic training and yet capable of soaring and aerobatics.  This was the Franklin PS-2, standing for 'Primary and Secondary too'.  The designer was R.E. Franklin.  The Franklin proved itself fully up to expectations and was very popular.  Some 54 were built, by far the largest number of any single type of glider in the USA at that time."
