Abstract: An improved shield of belted wheel of a compound machine comprises mainly a slide hole disposed at an appropriate location of upper portion thereof and a slide cover positioned correspondingly to the slide hole. The slide cover is characterized in that it comprises two rails located at lateral sides of bottom surface thereof to permit the slide cover to move along the confines of the slide hole in such a way that there is a sufficient open space in the slide hole to allow the shield to be lifted through the main shaft. The shield can be therefore opened up and closed with ease and speed.
