Abstract: A window frame and a glazing strip or rim for a window panel in which the frame defining a window has a J-shaped channel with its open side facing toward the opening in the frame. The panel is surrounded on at least three sides of a rectangular panel by the glazing strip or rim which has a leg integral therewith and which is received in the frame channel. Such leg is flexible and resilient and can be bent to permit the free end thereof to ride over the shorter wall of the channel and snap into the channel. Preferably, the portion of the rim from which the leg extends is U-shaped in cross-section and embraces the outer edge portions of the panel. A resilient gasket is between the rim and the frame. If the rim is of metal, the wall of the rim remote from the frame has a line of weakening for tearing purposes. A resilient strip may be inserted between the leg and a portion of the rim. Also, a tool for inserting the panel in the frame and a double-glazed window.

Abstract: A latch assembly for use on a closure, e.g. a sash, the assembly comprising a housing from which a slidable, spring-biased latch bolt extends, an actuating handle pivotally mounted at one end in the housing for pivotal movement in a plane parallel to the plane of movement of the bolt and having an opposite end portion extending from a portion of the housing spaced from the portion of the housing from which the bolt extends and a pair of bolt-lifting levers pivotally mounted intermediate their ends within the housing, one end of each lever being engagable with the bolt and the opposite end of each lever being engagable by a projection on the handle intermediate its ends for withdrawing the bolt. When the handle is pivoted in one direction, one lever is engaged and lifts the bolt whereas when the handle is oppositely pivoted, the other lever is engaged and lifts the bolt. The levers are free to pivot when the bolt is pushed inwardly from externally of the housing.

Abstract: A vent window assembly having a seal with both side and edge sealing surfaces; pivot means support the glass and are spaced away from the opening so that no part pierces the seal which allows the seal to be an extruded piece continuous in the opening; the construction of the pivot means provided for the same to be used as a lock to hold the glass in the closed or in any open position or used as a clutch as by holding the glass in an open position but permitting the glass to yield upon impact.

Abstract: Tie bars which fasten abutting members (such as extrusions) and also function to draw the members into very tight engagement at the butt joint. The structure inhibits the members from moving apart and from twisting relative to one another.
