ABSTRACT:
An improved carpet stretching tool of the knee-kicker type is disclosed in which outer and inner overlapping, slidably adjustable shank members connect and space a carpet gripping head having a spike plate and a plurality of cotton head sections and a knee plate. A locking system is provided in which the relative positions of the shank members can be adjustably fixed thereby fixing the height of the tool. The locking system employs several teeth integral with the outer shank member and adapted to mesh against mating protuberances integral with the inner shank member and a resilient member to urge the teeth against the protuberances. The teeth have a small amount of negative rake pitch matched by the protuberances to produce a positive wedging of matching inclined planes. The tool also has an improved and simplified carpet gripping cotton head system which employs an unique cotton head assembly and spike plate control system.
