Abstract
1,253,622. Compacting concrete by vibrations generated therein. KOEHRING CO. 6 May, 1969 [6 May, 1968], No. 23159/69. Heading B1C. [Also in Division F2] A vibratory poker has a housing 15 with longitudinal external flutes 25 (as described, seven) which produce conveying forces (F, Fig. 3 not shown) on the surrounding concrete and (if the upper end of the apparatus be restrained) cause it to be channelled upwards along the flutes, the radius R of which is preferably equal to the diameter D of the circle circumscribing the housing. This may be a steel extension, or an aluminium extrusion cased in nickel or nickel-copper (see Fig. 4, not shown) or of titanium. A steel housing may have a minimum thickness of one-tenth inch or less. The vibrations are generated by a weight 32, (see also Fig. 1, not shown) eccentrically rotated in needle bearings (40) and supported by a thrust bearing consisting of a hardened steel stud and ball (44, 45).
