Steel with Wooden Seat Tricycle

This is a little tricycle picked up at a local flea market in Ohio. We can't make out the name on the logo on the forks of the bike to figure out who made it or when the company was in business.It is unique with the "turn signal" arrow that is on the fork.It's in really nice condition, but we would like more information , especially if someone understands the logo. "Roller' is easy to read, but what does the other letters indicate? or are the wheels supposed to be letters too? Any help would be appreciated!!
