Preferably the sash frame is arranged to be tiltable relative to the main frame, being retained against engagement in its normal position of use and removable from the main frame in its tilted position.Type: GrantFiled: December 30, 1992Date of Patent: August 24, 1993Assignee: L.B.

Patent number: 5231795Abstract: A lock shoe system for an especially heavy sash has shoes with lock bolts that can be moved into locking positions by means of a tool that moves a bolt from underneath a shoe so that the bolt interlocks with a lance in the jamb liner. Once the shoes are locked to the jambs, the sash can be lifted off the shoes, moved laterally within the jambs, and angled out of the window for removal. The shoes guide the sash to a centered position as it is returned to its platforms; and when the shoes are unlocked from the jambs, the lock bolts preferably retain the sash on the shoe platforms.Type: GrantFiled: October 1, 1992Date of Patent: August 3, 1993Assignee: Caldwell Manufacturing CompanyInventor: Norman R.

Patent number: 5189838Abstract: A counterbalance shoe of a tilt sash lock shoe system runs in a resin shoe channel of a jamb liner and locks against a rib extending into the shoe channel so that the rib is backed up by a surface of the shoe. A locking element carried by the shoe is counterbalanced into a locked position in which a biting edge of the lock element bites into a front side of the rib. A non-circular sash pin carried by a sash and supported by the shoe at the bottom of an open top slot in the shoe engages and separates confronting surfaces of the shoe and the locking element. The pin is configured for separating the confronting surfaces by enough to hold the locking element out of locked position when the sash is untilted and for reducing the separation of the confronting surfaces to move the locking element into locked position when the sash tilts.Type: GrantFiled: June 10, 1992Date of Patent: March 2, 1993Assignee: Caldwell Manufacturing CompanyInventor: Norman R.

Patent number: 5159794Abstract: An integral strip of resin material is used to cover exposed portions of jamb liner slots of take-out windows. Side walls on either side of the slot are displaced by passage of the tubular body. The winged flanges are drawn partly into the slot against outer portions of the side walls by a snap-fit engagement between inner portions of the side walls and the tubular part. Resilience of the winged flanges against the outer portions of the side walls helps to hold the strip in place and cover the slots. The tubular part of the strip also serves as a stop for limiting movement of a windown sash along the liner.Type: GrantFiled: April 4, 1991Date of Patent: November 3, 1992Assignee: Caldwell Manufacturing CompanyInventors: John I. Habbersett, Norman R. Westfall

Patent number: 5127192Abstract: A pivot shoe which slides in a track includes a body which receives a cam. The cam is rotated by a sash pivot shaft for engagement of a wall of the track by the shoe for resisting movement along the track when the sash is rotated on the shaft to a position generally perpendicular to the track. The cam defines a first axial opening for receiving the shaft, and defines a second radial opening for removing the shaft from the cam. The body defines a third radial opening which is in alignment with the second opening when the sash is rotated to the track engaging position. A reversible obstructor for the second opening provides for easy installation or removal of the shaft from the shoe.Type: GrantFiled: August 7, 1991Date of Patent: July 7, 1992Inventor: Rex D. Cross

Patent number: 5065544Abstract: A window assembly including two horizontally slidable window units normally occupying separate portions of a window opening, which window units are selectively movable across the opening to provide a ventilation to an interior space. Each window unit comprises a four-sided rectangular frame and a windowpane haivng a hinged connection along a side edge of the frame. The windowpane can be swung out from the frame to a position normal to the frame, whereby the outer surface of the windowpane can be mannually cleaned from within the building space.Type: GrantFiled: October 10, 1990Date of Patent: November 19, 1991Assignees: Thomas B.
