Narrative:

Departed runway 24 (told ATC I would be eastbound). Controller cleared me for takeoff and told me about 3 aircraft inbound for runway 24 but never mentioned aircraft ahead in left closed traffic. On takeoff; climbed to 1000 ft AGL on runway centerline. Then turned 45 degrees left; leveled wings. Looked left and turned to easterly heading. After about 1 min; noticed low wing aircraft at 2 O'clock position. Started immediate descent and announced on radio that we were descending. Other aircraft said he saw me going under him. Tower controller said something and I responded that it would be nice if he told me about preceding aircraft. Controller went on at length that I should have seen aircraft on crosswind and that his (ATC) responsibility was for inbound traffic. Filed near midair collision report with tower and I am awaiting contact from FSDO on investigation.
