Narrative:

I was instructing in a 7AC without an electrical system or a radio. We had been in the traffic pattern for about 30 minutes and were on our sixth pattern. We were on the downwind leg of a published right hand pattern; approaching the departure end of runway 13; at a popular grass strip airport. I pointed out to my student a low wing aircraft that was approaching from our right. We continued to fly our published right hand downwind expecting the aircraft to change his/her flight path. When the other aircraft was too close for comfort I took controls of the aircraft and flew an escape maneuver to avoid a collision.I spoke with the other pilot privately about the incident. He insists that he did nothing wrong and that he had the right of way. I explained that we were already in the traffic pattern and he was entering from a crosswind against the published traffic pattern entry procedures established in FAA AC 90-66B; non-towered airport operations. He looked at me with a blank stare. I asked him to please be more vigilant while operating at any non-towered airport. This airport is popular with all types of aircraft as it is one of a very few public grass strips and has a restaurant on the field. There are several aircraft that regularly fly into this airport without radios. My aircraft is one of those so I am extremely vigilant in looking for other aircraft. Other threats at this airport that must be mitigated besides radio out aircraft are aircraft flying low passes; one direction of the runway having a significant upslope and aircraft landing/departing opposite directions due to the upslope runway. These threats are mitigated on a daily basis as long as everyone exercises vigilance.
