Eisenbeis, Conklin, N. Traditionally, the heads of immersion-type concrete vibrators widely used in compacting or densifying concrete blocks, columns and the like which are set in deep forms, as distinguished from concrete slabs, floor, etc. In an eifort to evaluate the relative merits of the squareand round-head vibrators, extensive tests were made of one against the other and these conclusively established that the square-head vibrator performs faster than the old round-head one, due apparently to the ability of the square-head vibrator to transmit energy in the form of pulses or vibrations to the concrete mass in which it is immersed more effectively than the round-head vibrator. However, because of the substantially lesser wall thickness of the square head as compared to the round-head vibrator which is more or less dictated by the economics and weight factors attaching to the new configuration, the square-head vibrator Wore out much more rapidly than did the round head. Furthermore, due to the increased power requirements of the square-head vibrator, the flexible shaft used to drive the eccentrically-weighted spindle component thereof failed after x hours of continuous operation whereas the flexible shaft driving the round-head vibrator continued to operate coolly and efliciently for many hours thereafter.
