ABSTRACT:
A vibrator is provided which includes a relatively rigid shell with a vibrating mechanism being provided within the shell to cause the same to vibrate. A flexible shaft is coupled to the vibrating mechanism to drive the same. Moreover, a cover is provided on the shell formed of a material softer than the shell whereby to lessen the effects of the impact of the shell on any encountered object such as a reinforcing rod. The cover is made, for example, of a plurality of rings arranged in axial series. The rings include projections and are provided with notches or receptacles for receiving the projections. The projections on respective of the rings are engaged in the receptacle of the next adjacent rings in the axial series. The vibrator may be inserted, for example, in a setting concrete to remove air and voids therefrom. The covering on the shell is intended to avoid chipping of, for example, epoxy coatings which are employed on reinforcing rods to avoid the corrosion of the same.
