Patent number: 6148562Abstract: 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.Type: GrantFiled: August 28, 1998Date of Patent: November 21, 2000Assignee: Newell Industrial CorporationInventors: Ivan L. Stark, James A. Hylton, James S. Hylton, Kim K. DeVormer, James W. Gibbs, Jr., Jack L. White, Gerald A. Hedrick, Jr.

Patent number: 6026617Abstract: 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.Type: GrantFiled: August 28, 1997Date of Patent: February 22, 2000Assignee: Newell Industrial CorporationInventor: Ivan L.

Patent number: 5699636Abstract: A jamb liner is provided for a window assembly including a frame and a sash operably mounted in the frame by use of the jamb liner. The jamb liner includes a sash-engaging portion having at least one pair of opposing wall sections and a bottom wall section defining a channel. An air-sealing portion extends from the opposing wall section for sealingly engaging the frame to prevent undesired flow of air between the jamb liner and the window frame. The air-sealing portion includes a root wall section that extends at an angle to one of the opposing wall sections, a resilient wall section that extends from the root wall section, and a frame-engaging wall section that extends from the resilient wall section.Type: GrantFiled: November 1, 1995Date of Patent: December 23, 1997Assignee: Newell Manufacturing CompanyInventor: Ivan L.

The air-sealing portion includes a root wall section that extends at an angle to one of the opposing wall sections, a resilient wall section that extends from the root wall section, and a frame-engaging wall section that extends from the resilient wall section. In one form, a pair of the resilient wall sections are provided for supporting the frame-engaging wall section, one extending from each opposing wall section in a bellows-like arrangement.Type: GrantFiled: December 9, 1994Date of Patent: June 18, 1996Assignee: Newell Manufacturing CompanyInventor: Ivan L.

Patent number: 5174064Abstract: A sash balance apparatus for vertically slidable window installations, in which a friction shoe is disposed in a channel formed by a jamb liner extending along each side of the slidable sash and a connecting member extends between the sash and the friction shoe in a manner such that the weight of the sash when applied to the shoe tends to pivot the latter at least slightly within the jamb liner channel and thereby bring predetermined surfaces of the shoe into frictional contact with corresponding surfaces of the jamb liner channel, preferably including elongated rib-like intermediate walls which extend into the channel from its sides. The channel thus provides a plurality of different longitudinally-extending friction surfaces which may be selectably engaged by the friction shoe as a function of its particular configuration, dimensions, and the degree of tilt introduced by the applied weight of the sash.Type: GrantFiled: March 5, 1992Date of Patent: December 29, 1992Assignee: Newell Manufacturing CompanyInventor: Ivan L.

Patent number: 5033235Abstract: A jamb liner, or facing member, for movably mounting windows along their side edges in channels or runs, in which a concealed elongated chamber is provided for a coil spring or the like used as part of the balance or positioner mechanism by which the window is supported in different positions along the length of the jamb as it is opened and closed during use. Preferably, such concealed chamber includes an elongated wall which projects outwardly from the jamb liner and has an arcuate or other angularly-configured cross-section, such that it presents a generally closed appearance when viewed from a position near the window. Such chamber-concealing wall defines an elongated opening through which the balance device may communicate for access by the window sash, for supporting the latter and positioning it.Type: GrantFiled: April 27, 1990Date of Patent: July 23, 1991Assignee: Newell Manufacturing CompanyInventor: Ivan L.
