Abstract
A hand powered carpet stretcher is provided with the improvement of an anti-sway device to prevent lateral or transverse movement of the stretcher tubes during stretching while permitting sideways relocation and longitudinal adjustments of the stretcher between stretching operations. The anti-sway device comprises connecting means for rotatably connecting the stretcher tubes to the head and tail block of the stretcher and at least one carpet gripper tube which is adapted to be mounted on the stretcher tubes for rotation therewith and is provided with spiked wheels for engaging a carpet surface, the axis of rotation of each spiked wheel being orthogonal to the longitudinal axis of the stretcher tubes.
