I agree with Lolly - at this stage, do what you have to do. But remember, do the minimum you need to - if he is quiet, staring, yawning, let him be - the patting may actually be keeping him awake. Pat/shhh is a soothing technique that should help the baby relax enough to put himself to sleep. If he's already relaxed and falling asleep, back off and let him!
If he's crying, try some variations, like just resting your hand on him, etc. to find out what he likes (my lo prefers this constant contact to patting). I certainly would not try for a whole hour at this age, maybe 20-30 minutes, and then do whatever works. That is enough opportunity to let him start trying to self-soothe, but he may not be developmentally ready, and that's okay.
For additional encouragement, we did not start BW till my lo was about 12 weeks, and last week at 5+ months she has weaned herself from the swaddle and I can just do our ritual, put her down and walk away. (As long as I respect her tired signals and don't push her past the window). You can try a little now and phase the system in as he gets older.
