Abstract: A handle assembly for an oven door or the like. The handle assembly comprises a handle grip section and an end cap at each end. The handle grip section is a longitudinally split tubular member. The end caps are capable of mounting the handle grip section in either of two rotative positions 90.degree. apart.

Abstract: An oven door having an inner panel between the back and front panels. The back and inner panels have aligned window openings. A window unit between the back panel and inner panel has a pair of glass panes aligned with the window openings. A suspended glass pane between the inner panel and front panel is aligned with the window openings. The front panel has a glass pane provided with a viewing area aligned with the window openings, or it may have a window opening aligned with the window openings in the back and inner panels and there may be another suspended glass pane to cover the window opening in the front panel. Fasteners connect the inner panel window unit and suspended glass pane or panes to the back panel.

Abstract: A self-contained window unit that may be installed in a solid fuel burner or like device. The window unit comprises a safety shield which may consist of a glass pane and/or a safety screen, and a frame surrounding the safety shield. The frame is composed of frame elements fabricated in separate lengths with brackets at the corners of the frame to secure the frame elements together. Preferably there is a cushion element between the safety shield and the frame to minimize the risk of breakage. The unit may be mounted on the fuel burner by hanger brackets on the frame or by threaded studs carried by the brackets.

Abstract: An oven door in which the top section or member of the door frame has a forward extension that serves as a door handle. End caps are secured to the door frame at the ends of the top frame member and cover and conceal the mitered corners at the top of the door. In a second embodiment the door frame has a bar-type handle.

Abstract: A machine is provided for cutting to length and joining two lengths of strand material at their ends to produce a band. A method of producing a band from two lengths of strand material is also provided.

Abstract: A self-contained window unit adapted to be assembled in an oven door. The window unit comprises at least two glass panes held in spaced parallel relation by a channel-shaped spacer having means engaging the peripheral edge portion of one of the panes, and individual clips or brackets mounted on the spacer and having clip portions engaging the peripheral edge portion of the other pane. The clips may be designed to hold third and fourth glass panes in spaced parallel relation to the first two panes.

Abstract: A self-contained window unit adapted to be assembled into an oven door, having three glass panes and a microwave shield. Two of the glass panes are held in spaced parallel relation by a frame of electrically-conducting material which has a peripheral mounting flange in electrical contact with the edge of the microwave shield. The third pane is secured to the frame by a plurality of individual mounting clips. Fasteners around the four sides of the window unit secure the mounting flange to the door to both mount the window unit and ground the microwave shield.

Abstract: Window structure for a solar collector shield or the like having a frame defining a row of separate window openings. A self-contained window unit is installed in each opening. Each window unit comprises a pair of rectangular glass panes held in laterally spaced parallel relation by a peripheral window frame. A mounting frame is provided for mounting each window unit in its window opening. Each mounting frame has overlapping frame members. Adjacent side frame members of adjacent window units also overlap. The overlap is for the purpose of excluding moisture and preventing heat loss. A peripheral window seal is provided for the same purpose.

Abstract: A self-contained flange mount window unit adapted to be assembled in an oven door. The windor unit comprises a pair of glass panes held in spaced parallel relation by a substantially continuous frame-spacer of integral one-piece construction which is made from an elongated member that is bent to substantially rectangular final form and is retained in final form by a tab at one end engaging a slot at the other end. The frame-spacer has an integral mounting flange projecting laterally outwardly from the top, bottom and sides of the window unit. The window unit is secured to the back panel of the oven door by fasteners which pinch the mounting flange between the air baffle of the door and the clamping surfaces of a plurality of bridge spacer members.

Abstract: Self-contained window units adapted for assembly into an oven door of the type having a vertical air passage for the flow of air by convection through the space between the front and back door panels, the window units having two glass panes, means holding the glass panes in spaced parallel relation and having openings therein defining an air flow passage between the panes aligned with the air passage through the door. Several modifications disclosed show various means of providing for easy removal of one or both of the panes for cleaning.

Abstract: A self-contained window unit adapted to be assembled into an oven door window opening and having means defining an air passage to allow air to flow upwardly through the door and window unit therein. The window unit is mounted on the back panel or liner of the door and comprises a window sub-assembly having a pair of glass panes held in spaced parallel relation. A front glass pane is secured to the subassembly by mounting clips. The mounting clip or clips at the top are constructed so as normally to hold the front pane against upward movement but to permit the front pane to be pressed outwardly for upward removal. The spaces between the clips allow upward flow of air through the door and window unit.
