Abstract: A blow gun with an extensible wand includes a barrel for receiving and storing the wand. The wand passes through an inner collar and an outer collar, the inner collar mounted to the barrel and the outer collar eccentrically rotatable upon the inner collar. Rotation of the outer collar affects alignment of the bore of the outer collar with the bore of the inner collar. When the misalignment of the bores is increased, the wand is locked in a selected extension from the barrel.

Abstract: A combined compressed air blow gun and tire inflation chuck is disclosed. The tire inflation chuck is fixed to a wand mounted to a handle in which a valve operated by a trigger controls flow of compressed air to the chuck. The chuck includes opposing tire stem receiving openings. An internal plunger in the chuck permits flow of compressed air from the wand through one opening of the chuck when no tire stem is inserted in either tire stem receiving opening in the chuck. When a tire stem is inserted in either opening of the chuck, compressed air is prevented by the plunger from passing to the opposing end of the chuck.
