摘要： An operator for controlling the movement of a window sash relative to a frame with a raised surface along a frame sill thereof, wherein the operator includes a base having a first support surface, an aperture and a bottom exterior surface with a slot therein, the base attached to the frame with the raised surface fitting substantially within the slot. The operator also includes a cover secured to the base and having a second support surface with a hole therethrough defining an internal shoulder, the second support surface mating with the first support surface. A post extends from the cover and through the aperture in the base when the operator is assembled. An arm is pivotally secured to the post and attachable to the sash to control the movement of the sash between open and closed positions. A worm driveably engages the arm and has a worm shaft and a worm shoulder disposed on the worm shaft. The worm is directly supported by the first and second surfaces at one end and the worm shoulder engages the internal shoulder as the worm shaft protruding from the hole.

摘要： An improved structure is provided for a window sash lock having a catch mounted to a face of a window frame to grasp and release a keeper reciprocally mounted to a face of a window sash. A housing (12) is mounted against the frame face (13) that has an opening therethrough with a portion substantially cylindrical about an axis perpendicular to the frame face (13). An operator (52) for the catch (32) comprises a cylindrical pivotal portion (56) which is receivable within the housing cylindrical portion and is adapted to pivot about the axis. The operator also includes a handle portion (54) secured at one end to the operator pivotal portion (56). The operator further comprises an actuator portion having a button (60) at one end for engaging the catch to control movement thereof. The actuator portion is secured at the other end to the operator pivotal portion. A part of the actuator portion is trapped between the housing and the frame face to prevent removal of the operator from the mounted housing.
