Abstract: An invertably mountable device having a generally hollow housing which mounts a movable latch member that is preferably biased toward latching engagement with an adjacent window jamb liner by a spring disposed within the housing. The housing preferably comprises a pair of mirror-image shells which fit together to form an enclosure, and provide an internal pivot mount for the latch member, and the housing has an opening through which the latch member projects. The latch member preferably carries a finger grip/thumb abutment member which facilitates movement of the latch member by an operator, and the grip/abutment member and latch member are preferably configured to permit mounting of the grip/abutment on either side of the latch member, to facilitate invertable mounting of the latch member. The latch member and jamb liner preferably provide a detent structure for secure interengagement.

Abstract: An improved soundproofing system for a window sash mounted for sliding vertical movement between jambs of a window case includes first and second jamb liners which are mounted on opposite jambs of a window case, and which each define a vertically extending channel in which a coil spring is disposed with one end connected to the window case and with an opposite end connected to a sash which is vertically slidable between the jambs. At least one strip of sound-absorbent material such as felt is wrapped at least partially around and attached to each of the coil springs. Each of the vertically extending channels includes an open side which faces away from the jamb. A spring cover is connected to and closes a vertically extending portion of the open side of each of the vertically extending channels. The fabric strip wrapped around the springs, and the spring cover, together or separately substantially reduce objectionable noises generated by the springs.

Abstract: A window assembly of the type having at least one sash which is slidably mounted between a pair of jambs defining a window case, wherein the sash includes jamb-engaging side members (i.e., stiles) which have generally flat edges. The flat or flush sides of the sash stiles allow the sash to be easily pivoted away from the plane of the window case, without pushing on, or deforming, the jamb liners, thus overcoming problems generally associated with conventional sash having recess or plows configured to be interfitted with protruding ridge-like channels projecting outwardly from the jambs, as is typically the case with wood-frame windows. In accordance with another aspect of the invention, weatherstrips are mounted to each of the jamb liners to provide weathersealing engagement between the jamb liners and the sash stiles at the sides of the windows.

Abstract: An integrally reinforced lineal building component including an elongated member having a substantially constant cross-sectional area along substantially the entire length of the building component and comprised of cellular material forming the body and major cross-sectional portion of the building component, and an elongated reinforcement element having a substantially constant cross-sectional area along substantially the entire length of the building component and disposed inside the elongated member and bonded integrally thereto. The reinforcement element is provided at least two flange-like portions integrally attached and disposed at an angle with respect to one another extending lengthwise of and generally parallel to the elongated member.
