Abstract: A casement window assembly includes a rectangular sash frame enclosing an insulated glass panel unit and supported for swinging movement by a surrounding main window support frame. At least one set of interfitting and interlocking members are positioned in opposing relation on adjacent vertical members of the sash frame and support frame in opposing relation and have hook portions positioned to pass each other when the sash frame is pivoted between a closed position and an open position. The hook portions are effective to engage and hook each other in response to a substantial positive or negative windload or such windload applied after an impact breaks the glass to limit deflection and prevent permanent deformation of the sash frame. The hook portions also produce a snubbing action for compressing a flexible seal between the sash frame and support frame.

Abstract: A lock template includes an elongated body member that defines a substantially rectangular first opening having a first length and a first width and an elongated first member. The elongated first member is configured to be removably-inserted into first end recesses of the body such that the first member is located at least partially within the first opening. The first member, when inserted in the first end recesses of the body, defines a wall of a second opening having a length substantially equal to the first length and a width smaller than the first width. The second opening is configured to guide a cutting instrument to form a mortise for a lock component in a passageway component. When the first member is inserted into the first end recesses a longitudinal central axis of the first insert member is offset from a central axis between the first end recesses of the body.

The bumper is held in position by continuous rotation of the shaft causing the gap between the shaft head and the most adjacent bracket ear to be closed and for the bracket ears to elastically deform to capture the bumper until such time as the bracket ears are restrained from further deformation by resistance provided by the hardened member within the bumper.

Abstract: A steel window structure for modern day double paned insulating glass simulating the narrow, elegant sight lines of older steel window structures which secured monolithic, non-insulating glass windows is described. The window securing structure is made deeper and narrower than is currently available in steel windows. This structure now accommodates a single pane of glass of up to 1" thick glass, or up to 1" thick double paned insulating glass. Additionally the new structure inherently provides a thermal break between exterior and interior metal components, the convenient use of two color factory applied finishes for the steel members, and superior air and water resistance over current structures, while at the same time providing the narrow sight lines previously seen only in the older, non-insulating glass steel window structures. Moldings connected to the exterior steel structure provides a "putty slope" shadow effect to complete the simulation of the older steel window structure.

Abstract: An improved locking feature for a watertight hatch incorporates a positive break-open feature to facilitate opening when the hatch is jammed with ice and/or debris. A plurality of radially extending/retracting locking bars cooperate with closing cams such that, when the bars are extended, the hatch is drawn into tight engagement with a sealing gasket. When the locking bars are fully retracted, in order to release the hatch for opening, at least selected ones of the locking bars cooperate with opening cam means whereby full retraction of the bars forcibly displaces the hatch in an opening direction with a high mechanical advantage, initially breaking the hatch free of any restricting ice formation or packed debris. Thereafter, the hatch may be readily opened by being manually lifted in a conventional manner. The arrangement makes it entirely feasible to configure the hatch cover to be flush with its surroundings, so as to be useable in sidewalks, for example, where there may be heavy pedestrian traffic.
