LEON LEU, OF ST. LOUIS, MISSOURI, ASSIGNOR OF ONE-HALF TO JOSEPH IIAFNER, OF SAME PLACE.

OVEN-DOOR.

srncrrrca'rroir forming part of Lettere Patent No. 637,805, dated November 2s, 1899.

Application filed April '7, 1899. Serial No. 712,082. (No model.)

To all whom it petty concern:`

Be it known that I, LEON LEU, a citizen of the United States, residing at St. Louis, State of Missouri, have invented certain new and usefulImprovementsin Oven-Doors, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention has relation to improvements in oven-doors; and it consists in the novel arrangement and combination of parts more fully set forth in the specification and pointed out in the claims.

In the drawings, Figure l is a front elevation of the door, being in its closed position, showing a portion of the stove or range. Fig.

2 is an enlarged vertical section on line 2 2 of- Fig. 1, showing in dotted lines the open position of the door; and Fig. -3 is a plan View of the door thrown open, a sectional portion of the oven being also shown.

The object of my present invention is to construct an oven-door with a transparent body 'portion or section through which the contents ing arm or lug 3 for the support of the doorl when the latter has been opened out to a hori- The hinge pins or pivots 4 of the door are disposed at the lower corners of the outer frame 5 of the door, the frame 5 being substantially a closed angle-bar, the normally vertically-disposed or face member of which in the present instance supports a plate-glass body portion 6, between which and the frame is interposed a strip of asbestos 7 or equivalent material which is a nonconductor of heat. Adapted to embrace the edges of the plate 6 and interposed between said edges and the other member of the angle-bar 5 is the outwardly-projecting member of the angle-bar grating 8, the other member being disposed parallel to the plate and two opposite parallel portions of the same being connected by bars or gratings 9, which when the door is open are substantially on a level with the bottom of the oven. In practice a strip of asbestos l0 is interposed between the glass plate and the grating, the asbestos on each side of the glass preventing the latter from being unduly heated and is thus protected'against extreme temperatures. The edge of the frame 5 and the outwardly-projecting member of the angle-bar frame 8 are provided with alining screw-threaded openings for the reception of screws 1l, by which the parts are held together.

The object of the grating 8 9, asis obvious, is to protect the inner surface of the glass frombeing scratched by the bottoms of the pans as they are pulled out of the oven onto the door when the latter hasbeen swung to its horizontal open position, the gratings or bars 9 serving to temporarily support such pans when drawn out of the' oven.

While I have herein described certain details of construction, it is apparent that minor changes might be made therein without departing from the spirit of myinvention. To enable the cook to better draw the pans over the grating, the bars of the latter are disposed, preferably, parallel to the direction in which the pans are withdrawn-that is to say, the bars run parallel to the plane of oscillation of the door.

Having described my invention, what I claim isl. An oven-door comprising an outer anglebar frame, a body portion of glass bearing against and supported by the face member of the angle-bar, an angle-bar grating having an outwardly-projecting member embracing the edges of the glass and interposed between it and the second or edge memberof the anglebar frame, bars connecting two opposite portions of the second member of the angle-bar grating, and securing-screws passed through the edges of the door into the outwardly-projecting member of the angle-bar grating for securing the parts together, substantially as set forth.

2. An oven-door comprising an outer anglebar frame, a body portion of plate-glass bear- IOO ing against and supported bythe face member of the angle-bar, a strip of asbestos interposed between said member and the glass, an

angle-bar grating having an outwardly-projecting member embracing the edges of thev glass and interposed between it and the second or edge member of the angle-bar'frame,

bars connecting two opposite portions of the second member of the angle-bar grating,l said screws passed through the edges of the door bars running parallely to the plane of oscillation of the door, an asbestos strip interposed between the grating and glass, and securinginto the outwardly-projecting member of the anglebar grating for securing the parts together, the door being pivoted so as to bring,` when opened horizontally, the grating-sui# face in the plane of the bottom ofthe oven,- substantially asset forth.v
