Abstract: A latch for a window sash is disclosed. The latch includes a cover with a handle, a chassis, a bolt biased towards an extended position and containing a notch, a plunger biased towards the extended position and containing a guide, a rotary latch, pivotally connected to the chassis, containing a guide slot for receiving the guide and a protrusion biased towards the notch. The latch is operated wherein the bolt is locked in a retracted position when the handle slides the bolt inwardly towards the chassis and the protrusion engages the notch as the rotary latch rotates towards the notch, and wherein the bolt is released to the extended position when the plunger slides inwardly towards the chassis and the protrusion disengages from the notch as the rotary latch rotates away from the notch.

Abstract: A two point lock includes two pivotally mounted security hooks having sliding faces that engage sliding faces of a spring-loaded mishandling pin when the mishandling pin is vertically extended and the security hooks are rotatably retracted. The mishandling pin is vertically retracted when it abuts a jamb. When the mishandling pin is vertically retracted, the sliding faces disengage so that the security hooks can rotate to lock onto a striker on the jamb. Thus, the mishandling pin prevents the security hooks from being slammed into the striker before a door or a window is fully closed.

Abstract: A single point lock or cam lock for a casement window is provided. The lock includes an escutcheon providing a low profile and a smooth uninterrupted surface which faces the inside of the room. The handle includes two opposing legs that enter the escutcheon for attachment to the hook through opposing side walls of the escutcheon. A shaft provides the connection between the hook and the handle which rotates on two brace structures provided by the frame. The frame is sandwiched between the escutcheon and the inside surface of the window frame. The design of the escutcheon, the shaft and the braces of the frame provide for an effective seal against the inside surface of the window frame.

Abstract: A window operator for a wide range of sizes of casement windows includes a housing in which a worm gear is mounted. An arm assembly has a gear segment that engages with the worm gear so that rotation of the worm gear causes the arm assembly and window sash to pivot outward or inward. The arm assembly includes three arms which are telescopically arranged. The inner arm and lead arm have outward facing races. The center arm has an inverted U-shape with downwardly extending legs of the U each have corresponding races. As the worm turns, the arm assembly rotates outward and the three arms slide with respect to one another.

Abstract: An operator for a multi-point locking system for a casement window is provided. The operator includes a handle having two opposing legs that pass through side walls in the escutcheon thereby leaving the outer wall of the escutcheon intact. Due to a delay between movement of the handle and the first link which indirectly imparts movement of the handle to the tie bar, the handle can be rotated a full 180.degree. between the open and the closed positions while the first link is rotated through an angle of less than 180.degree.. As a result, the handle lies in a flat position with respect to the inside window frame surface in both the open and closed positions. Because of the handle design which employs two opposing legs disposed on opposite sides of the escutcheon, the operator can be used both on the right side and the left side of a window frame. The legs of the handle include inwardly extending shafts which are accommodated and supported by braces disposed on opposing sides of the base.

Abstract: A snap stud assembly is provided for pivotally connecting two hardware members together. A stud is disposed within a tubular sleeve. A lower or bottom end of the stud is attached to a lower hardware member by pressing or deforming the bottom end of the stud member to provide an interference fit. The upper hardware member is mounted over a top end of the plastic sleeve which includes a top flange but which is resiliently compressible in the radially inward direction so that the top hardware member may be easily forced over the top end of the plastic sleeve. Once installed, the upper hardware member is disposed between a top flange and a bottom flange of the plastic sleeve which serves as a bushing about which the top member pivots as well as a washer between the top hardware member and bottom hardware member.

Abstract: A brake system for a window assembly comprises a track liner having two generally parallel sides defining a pocket, opposed grooves extending along the sides of the track liner, each groove being defined by a flange extending along the track liner, a base mounted for sliding along the track liner, a brake plate connected to the base and mounted for sliding along the track liner, within the grooves, the brake plate being flexibly connected to the base to enable the brake plate to move relative to the base when the brake plate is moving along the groove, a pair of brake shoes connected to the base and mounted for sliding along the track liner, the flange on each side of the track liner being positioned between the brake plate and a brake shoe, and a receiver actuable to urge the brake shoes and brake plate toward each other to grip the flange in a braking action.

Abstract: A window assembly for selectively enabling a sash to be tilted out of the plane of the frame includes a brake and a sash retainer, the sash retainer having a reciprocally mounted bolt which upon rotation actuates the brake, and a lock which prevents reciprocation of the bolt until the bolt is rotated and the brake is engaged.

Abstract: A plurality of spaced brackets each has mutually perpendicular first and second legs with a lip upstanding from the end of one of the legs. A third leg extends from the upstanding second leg parallel to the first leg and overhangs the first leg. A bracket mounting flange extends from the end of the third leg for securing the bracket to the face of a fascia board, the first, second and third legs being beneath the soffit region. The lip and legs are so dimensioned and spaced to releaseably secure a standard K-gutter thereto without additional fasteners. The gutter is partially under the soffit. A sheet layer has an edge beneath the shingles and curves around in front of and below the fascia above the gutter mouth forming a relatively small entrance region with the gutter. The apex of the curve extends beyond the gutter so that debris carried by water run off falls to the ground while the run off flows around the layer into the gutter.

Abstract: A cable action instrument for surgery and other uses comprises a control end, a reaction end, and an angle adjustment section connecting the control end and the reaction end. A flexible control cable extends between the control end and the reaction end and allows a force to be transmitted from the control end to the reaction end so that a desired function may be performed at an instrument tip. The instrument may be bent into an unlimited number of configurations and is easily disassembled and reassembled.

Abstract: A curb structure is dimensioned to be passed through an opening in a roof and then attached in moisture impervious relation to the roof from within a building interior. A skylight assembly including a frame and light transmitting member secured to the frame is dimensioned to be passed through the opening and attached in a sealing engagement to the curb structure from within the building interior for covering the opening. The skylight assembly is then secured to the rafters and headers at an interior location. The frame includes upper and lower clamping jaws and spaced fulcrum links attached to the jaws for clamping the light transmitting member thereto. The lower clamping jaw includes a channel which engages and is interlocked with the curb structure.
