Appellant contends that the trial court erred in overruling his motion to quash the indictment for the reason that the description therein of the murder weapon is insufficient to apprise him of what the weapon was. He contends that the indictment should have specified what kind of fan belt, automobile or otherwise. In Wilson v. State, 155 Tex.Crim. 323, 234 S.W.2d 882, this court held that an indictment alleging that one was killed by being struck with a hammer was not invalid for failure to name the kind of hammer that was used. We think that the words fan belt are widely used and that its descriptive meaning is amply understood in this age of mechanization.
