OPENABLE DUAL WINDSHIELD ARRANGEMENT FOR CONSTRUCTION VEHICLES A B S T R A C T The frame of an operator's cab has a sub-frame pivot- ally mounted thereon. An upper windshield is fixedly mounted on the sub-frame and a lower windshield is slidably mounted in a colinear track defined on the main frame and on the sub- frame. A first latch is mounted on the sub-frame to release- ably attach the sub-frame and upper windshield in a generally vertical closed position or a generally horizontal open posi- tion on the frame of the operator's cab. A second latch is adapted to maintain the lower windshield in one of four positions for permitting sequential upward movement thereof between (1) a lowermost first position to permit the sub- frame and upper windshield to be pivoted into the operator's cab, (2) a second position to prevent the sub-frame and upper windshield from pivoting into the operator's cab, (3) a third position to define an opening between a lower edge of the lower windshield and the main frame for ventilation purposes, and (4) a fourth position substantially overlying the upper windshield to permit the sub-frame and upper and lower windshields to pivot into the operator's cab as a unit simultaneously.
