Abstract: A latch for use in a window comprising a bottom sash mounted in a window frame, the latch comprising a housing comprising a top wall, a bottom wall, a pair of opposed sidewalls and a rear wall. A top edge of the rear wall and a rear edge of each sidewall define a rear aperture. A front edge of the top wall, the bottom wall and each of the sidewalls defines a front aperture, the front aperture and the rear aperture opening into a bolt cavity defined by the housing. A bolt is slidably received by the housing, the bolt comprising a body with a front portion and a rear portion. The body is slidably received in the bolt cavity between a first position in which the front portion of the bolt is extended outwardly through the front aperture and the rear portion of the body engages an outer surface of the housing, and a second position in which the rear portion is disengaged from the housing. The rear portion of the bolt extends outwardly through the rear aperture in both the first and second positions.

Abstract: A latch for use in a window, the latch including a faceplate, a pair of opposed sidewalls, each sidewall defining a pawl mounting recess, a bottom wall extending between the sidewalls, an aperture defined by the faceplate that opens into a first cavity defined by the housing, and a pair of mounting arms disposed within the first cavity. Each mounting arm has a distal end extending both toward the face plate and inwardly toward a longitudinal center plane of the housing. A pawl is pivotably received in the first recess, the pawl including a top surface, an engagement surface, and a pair of mounting pins pivotally received in the pawl mounting recesses. The distal ends of the mounting arms engage the pawl adjacent a respective mounting pin such that the mounting pins are pivotably secured in the pawl mounting recesses.

Abstract: The invention relates to tilt-in window assemblies, in which a sash may be tilted into a room or removed from a window jamb. When the sash is tilted or removed, a balance shoe that is connected to a window balance engages the window jamb and prevents the sash and the window balance from releasing and travelling vertically in the window jamb. The balance shoe is biased into a locked position when a pivot bar coupled to the sash is disengaged from a camming surface of the balance shoe, as occurs when the sash is tilted or removed from the window jamb. Upon return of the sash to its normal vertical position in the window jamb, the pivot bar engages the camming surface and the balance shoe disengages the window jamb.

Abstract: The invention relates to hardware for use with a tilt-out type window sash. The hardware includes a pivot bar that is adapted to be received in a first aperture formed in a window sash and a tilt latch that is adapted to be received in a second aperture formed in a window sash, where the first aperture and the second aperture have substantially common profiles, such that the pivot bar and the tilt latch are interchangeably locatable in the profiles.

Abstract: A pipe supporting dam assembly and method for pipeline construction employing a planar dam sheet with a collar and a flexible sleeve for receiving and supporting the pipe, and clamping means to seal the collar to the outside of the pipe to prevent fill material in the trench being washed away by groundwater along the outside surface of the pipe, particularly in the case of sloping pipeline construction.
