Abstract: A tilt window balance shoe assembly is used with a double hung window and provides three directional locking. The balance shoe assembly comprises a slide block, a center cam, a pair of brake shoes, and a locking lug. The slide block has a head portion with a retention slot for a balance mechanism and a generally cylindrical-shaped hole which receives the center cam. The slide block also has side apertures extending to the hole and a receiving opening in a back face of the slide block and extending to the hole. The center cam has a slot well, cam flats and cam rounds. The slot well receives a terminus of a pivot bar attached to the window. The brake shoes which are positioned in the side apertures and the locking lug which is positioned in the receiving opening are in operable association with the center cam. Tilting of the window about its lower pivot point causes the pivot bar to rotate the center cam.

Abstract: A decorative art glass grid system is intended for use in a double window pane unit. The unit itself fits into a window frame. The grid system comprises at least two notched elongated members to form a grid, a set of holding feet slidably positioned in the terminuses of the elongated members and, optionally, a set of resting pads positioned in the elongated members. Each notched elongated member has a first groove extending along one wall of the member to receive an edge of an art glass pane, a second groove extending along an opposite wall of the member to receive an edge of another art glass pane, an interior channel, and a notch in a third wall of the member. The notch is configured to have a dove tail-shaped receiving section and a centered recessed section to receive another notched elongated member in a locked and substantially wobble-free manner.

The grid system comprises at least two elongated members to form a grid, a set of holding feet slidably positioned in the terminuses of the elongated members and, optionally, a set of resting pads positioned in the elongated members. Each elongated member has a first groove extending along one side of the member to receive an edge of an art glass pane, a second groove extending along an opposite side of the member to receive an edge of another art glass pane, and an interior channel. Each holding foot has a substantially flat base which has a groove in one face to receive the edge of an art glass pane and a post extending substantially vertically from the flat base to fit into the interior channel of the elongated member to hold it in place. Each resting pad has a flexible head portion which rests in the grooves and receives an edge of an art glass pane.
