Claim:
A projection window operator comprising: a base adapted to be fixedly coupled to a window frame, the base defining a channel therein; a window sash interface portion adapted to be fixedly coupled to a window sash movably attached to the window frame; a cam engaged with the channel of the base, the cam selectively slidably positionable in the channel between a first position and a second position relative to the base; and an arm operably coupling the cam to the window sash interface portion, the window sash interface portion being positioned by the arm in a first retracted position proximate the channel when the cam is positioned in the first position and the window sash interface portion being positioned by the arm in a second extended position spaced-apart from the channel when the cam is positioned in the second position, so that when the base is coupled to the window frame and the window sash interface portion is coupled to the window sash, movement of the cam from the first to the second position projects the window sash outward from the window frame, wherein the cam includes a body portion with a generally s-shaped cam slot defined in the body portion, the cam slot having a pair of opposing ends, wherein the arm includes a cam follower portion, and wherein the cam follower portion is slidably disposed in the s-shaped cam slot of the cam.
