ABSTRACT:
A vibrator for immersion in wet concrete includes a relatively rigid shell with an internal vibrating mechanism. 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 defining passages therebetween to provide access to the shell for cooling the same. The covering on the shell is intended to avoid chipping of, for example, epoxy coatings which are employed on reinforcing rods. As an alternative to the rings the covering can be formed with holes to provide passages for the cooling. The passages flare outwardly and are devoid of undercuts and recess to avoid entrapping cured and hardened concrete. A method can be employed of forming fins on the shell by which the cover is firmly attached to the shell, being molded thereupon.
