Abstract: An integrated sash lock and tilt latch assembly is mounted in a sash window having a top rail, a base, and two stiles connected together at their extremities. The integrated assembly contains a sash lock mechanism, a tilt latch mechanism, and a connector. The sash lock mechanism includes an actuator movable to adjust the assembly among a locked position, an unlocked position, and a tiltable position, and a rotor coupled to the actuator. The tilt latch mechanism includes a tilt latch housing supported by the top rail and a latch bolt slidably supported by the tilt latch housing and moveable between an extended position and a retracted position. At least a portion of the tilt latch housing has a generally circular cross-section. The connector has a first end of operably coupled to the latch bolt and a second end operably coupled to the sash lock mechanism.

Abstract: A locker lock that provides for increased security and ease of use. The locker lock can be a vertical built-in lock or a horizontal built-in lock. In each case the lock is symmetrical such that it can be used in either right-handed or left-handed lockers. The locker lock provides for increased security by increasing the distance the lock bolt must travel. The locker lock also provides for an easy combination changing mechanism, such that the combination can be changed without opening the lock and the locker lock can accommodate a large number of lock combinations.

Abstract: A sash lock assembly is used with a sash window assembly having an upper sash window and a lower sash window slidable within tracks of a master frame. The sash lock assembly includes a keeper adapted to be connected to the upper sash window, a housing adapted to be connected to the lower sash window, a rotor positioned within the housing, a handle having a shaft extending through the housing and connected to the rotor, and a selectable stop member. The rotor is moveable between a locked position, wherein the rotor engages the keeper, and an unlocked position, wherein the rotor does not engage the keeper. Movement of the handle moves the rotor between the locked position and the unlocked position. The anti-rotation device includes a stop member and is moveable between a first position, wherein the stop member blocks movement of the rotor from the locked position to the unlocked position, and a second position, wherein the stop member does not block movement of the rotor.

Abstract: A sash lock assembly is suitable for use with a sash window assembly including an upper sash window and a lower sash window slidable within a master frame, the upper sash window having a keeper connected thereto. The sash lock assembly includes a housing adapted to be mounted on the lower sash window, a cam positioned within the housing, an actuator handle, and an anti-rotation device. The housing has an opening therein. The actuator handle extends through the opening in the housing and is connected to the cam such that the actuator handle and the cam rotate together between a locked position, wherein the cam is adapted to engage the keeper, and an unlocked position, wherein the cam is adapted to disengage from the keeper. The anti-rotation device includes a protrusion positioned on the housing. When the sash lock assembly is in the locked position, the protrusion engages an engaging surface on the actuator handle to prevent rotation of the actuator handle.

The integrated assembly contains a sash lock mechanism, a tilt latch mechanism, and a connector. The sash lock mechanism includes an actuator movable to adjust the assembly among a locked position, an unlocked position, and a tiltable position, a rotor coupled to the actuator and having a locking cam, and a keeper that receives at least a portion of the locking cam in the locked position. The tilt latch mechanism includes a latch bolt housing supported by the top rail such that a top surface of the latch bolt housing is substantially flush with a top surface of the top rail, a latch bolt slidably disposed within the latch bolt housing, and a spring biasing the latch bolt outwardly from the housing. The connector has a first end of operably coupled to the latch bolt and a second end operably coupled to the sash lock mechanism.

Abstract: A tilt-latch assembly (10) is used in a window assembly (11). The window assembly (11) has a sash window (12) slidable within a master frame (14) between a pair of guide rails (16), each guide rail (16) forming a shoe channel (17) having a channel base (18). The assembly includes a tilt-latch (40) having a housing (42) supported by the sash window (12) and having an outward end opening (53). The tilt-latch (40) also includes a latch bolt (46) having a distal end (60). The latch bolt (46) is slidably retained by the housing (42). The distal end (60) of the latch bolt (46) has an aperture (62). The assembly (10) also includes a retainer (41) having a leg (66) and a hook (70) spaced from the leg (66). The retainer (41) is fastened to the channel base (18). When the sash window (12) is in a closed position, the aperture (62) of the latch bolt (46) receives the hook (70) of the retainer (41).

Abstract: A pair of articulated rods connect between a float and a pair of shafts through a one-way clutch on the respectively shafts. When a float rises an “up” connecting rod causes the “up” shaft to rotate as its clutch is engaged, and when the float falls, that clutch disengages, allowing that shaft to freewheel. Likewise when the float falls a “down” connecting rod causes the “down” clutch to engage and the “down” shaft to rotate, typically rotating opposite the rotation of the “up” shaft. When the float reverses and begins to rise again, the “down” clutch disengages and the “up” clutch reengages. A connecting rod hand member connected pivotably to the forearm at a wrist joint is adjustable in length. The wrist joint adjusts the effective length of the hand member to change the stroke of the machine to match wave amplitude through a computer-controlled pneumatic actuator.
