A pivot mechanism for pivoted or reversible windows includes a stationary base adapted to be secured to a window frame member and a slide base slidably mounted on the stationary base and with which a window sash edge is pivotally engageable. A screw threadedly extends through one of the bases and is coupled with the other base by means of a pair of annular flanges on one end of the screw, between which is received a pair of arms extending from the other base. By turning the screw, the slide base is moved with respect to the stationary base, thereby providing a bearing for a pivot shaft on the window sash edge or positionally adjusting a pivot shaft on the slide base. |
