ABSTRACT:
To permit adjustment of air flow through air exchange openings (7,8,9;25,29) of a hollow outer turning rod tube (11,23,30), a plurality of inner tube elements (12,24,32) are axially located within the outer tube, and formed with part-circumferentially extending slits (13) in alignment with the air exchange openings. The inner tube elements can be, slectively, rotated for alignment of the slit (13) with the air exchange openings, or blocking of the air exchange openings by solid portions of the tube elements. Rotation can be effected by adjustment knobs (FIGS. 1-3: 17) having an inner gearing (16) engaging a side gearing (15) on the tube elements; by finger adjustment (FIG. 4) or by positioning wheels (FIG. 5: 34) in engagement with a roughened, stippled, ribbed or corrugated surface portion or region of the inner tube elements.
