Abstract: The purpose of this study was to determine the effect of sweeping upon the linear distance and lateral deviation of a moving curling stone. Subjects for the study were three pairs of experienced curlers. Three curling stones were used for the experiment, as nearly alike in physical characteristics and weight as possible. Each stone received a total of ninety trials. For the forty-five odd-numbered trials the stones were swept, and for the forty-five even-numbered trials they were permitted to run unaffected. After each trial, linear distance and lateral deviation for each stone were measured and recorded. A ten foot aluminum roller conveyor gave constant impetus to the stones. One end of the conveyor was supported 27 inches above the ice surface and the other end rested on the ice. A ramp, constructed of slush and allowed to freeze, permitted smooth transition of the stone from the conveyor to the ice. Torque was applied as the moving stone brushed against the leather-bound bristles of a curling broom fixed at the foot of the ice ramp. Data were treated statistically to determine whether sweeping modified the linear distance of a moving stone, to determine whether sweeping modified the lateral deviation of a moving stone, and to determine whether there were differences between individual curling stones.
