ABSTRACT:
A paint guide has an inverted U-shaped frame with a flexible paint shield terminating in a straight edge which is adapted to be spaced a predetermined distance from a window frame to provide for a strip of weatherproofing paint on the glass adjacent the frame. An L-shaped bracket is adjustably mounted on each of the ends of the frame and is pivotally slidably mounted on an elongated supporting arm by a link and slidable pivot pin arrangement. A coil leaf spring extends between the bracket and arm and biases the bracket away from the arm to move the paint shield edge out of engagement with the glass. A tab is provided on each of the arms and is located rearwardly of and beneath the fronts of the arms to support the paint guide on a pane of glass when the arm fronts are placed in abutting engagement with the frame. When inward pressure is applied to a handle, which is mounted on the frame, the paint edge is moved vertically into engagement with the glass and spaced a predetermined distance outwardly from the frame due to the engagement of the links in the bracket slots. Continued pressure on the handle seals the paint edge tightly against the glass as the rear portion of the frame moves slightly rearwardly due to the flexibility of the paint shield and the slidable pivot pin mounting arrangement between the bracket and arm. After completion of the paint application between the arms, the pressure on the handle is released, whereupon the leaf spring raises the paint edge vertically from the glass, after which the guide is slid to an adjacent unpainted area.
