I have a few with garage advertising on them, and some with no writing.
look at patent # 1,454,320 Jan. 13, 1922
yes, the days of the wooden rims.
the patent states: combination wrench & tire tool, to loosen demountable rims from wheels and to remove the tire from the rim.
if you look at your tool, you will see that the small curve is needed to get below
the edge of the rim,
these are the type of rims that the spokes and hub stays on the vehicle.
sometimes you may need the Y shaped tool with a crank to split the rimsalso.
