OVEN-DOOR.

Specification of Letters Patent.

Patented Jan. 2, 1912.

Application filed January 23, 1911. Serial No. 604,234.

To all whom it may concern:

Be it known that I, WALTER E. FELD, of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Oven- Doors; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in oven doors and particularly to that type employing glass panels,-the object of themvention being to provide simple and eflicient means for retaining the glass panel in position in such manner as to reduce liability of breakage to a minimum.

With this object in view the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims;

In the accompanying drawings, Figure 1 is a rear face view of an oven door embody- Fig. 2 is a longitudinal sectional view of the same. Fig. 3 is a transverse sectional view, and Figs. 1, 5, 6 and 7 are views illustrating modifications.

1 represents a door frame sheet having a central opening and made with a bulged portion 2 having straight inclined walls. At the free edges ofthe inclined walls of the bulged part of the sheet, off-set flanges 3 are formed and from the free edges of these flanges, inwardly projecting flanges 4 are made to extend inwardly (preferably somewhat inclined) and constitute seats for the outer faces of a glass panel 5 near the edges of the latter. A lining sheet 6 is secured to the frame sheet 1 and conforms to the general contour of the latter. At respective ends of the opening in the lining sheet, the

latter is provided with beads 7 the inner sides of which are free and constitute yielding abutments 8 for the ends of the glass panel.

At one longitudinal side of the opening in the. door, the inclined wall of the lining sheet is bent so as to form a seat 9 bearing against the inner face of the glass panel opposite the adjacent flange l on the frame sheet. At the diametrically opposite side of the opening in the door, the lining sheet terminates approximately in line with the upper edge of the adjacent inclined wall of the frame sheet. At this side of the opening, for the panel, a retaining strip 10 is provided. This retaining strip is preferably made of sheet metal and comprises a member 11 inserted between the lining sheet and the inclined wall of the frame sheet, and a member 12 disposed at an obtuse angle to the member 11 and constituting a seat for the inner face of the glass panel and bearing against the same directly opposite the adjacent flange 4 of the frame sheet. It will be observed that the lining sheet will tend, not only to hold the retaining strip in place, but its elasticitywill press the member 12 of the retaining strip yieldingly against the inner face of the glass panel. It will also be observed that the upper edge of the inclined portion of the lining sheet at this side i of the panel opening, will constitute an abutment against which the member 12 of the retaining strip will bear and thus said retaining strip will be held in place should the member 11 thereof be not made of suflicient depth to reach the inner end of the bulged portion of the door.

Instead of making the member 12 of the retaining strip straight as shown in Fig. 2, said member may be curved as shown at 13 Fig. l, or said member of the retaining strip may have the form shown at 14, Fig. 5,-in each of which constructions, the free edge only will bear against the inner face of the glass panel.

In the construction shown in Fig. 7, the retaining strip is made straight and its outer edge only bears against the inner face of the glass panel. In this construction displacement of the strip is prevented by the abutment formed at the angle of the bulged portion of the lining sheet with the flat portion thereof and the bulged portion of the lining sheet has suflicient elasticity to press the free outer edge of the retaining strip yieldingly against the glass panel.

In the construction shown in Fig. 6, the bulged portions of the frame sheet and of the lining sheet are made curved and the retaining strip 'is curved concentric with the curvature of said bulged portion of the door and is inserted between the frame and lining sheets,its free edge projecting inwardly from the outer edge of said bulged portion and bearing yieldingly against the inner face of the glass panel diametrically opposite the bearing of the flange 1 of the frame sheet against the outer face of said glass panel.

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is

1. In an oven door, the combination with a frame sheet and a lining sheet having alined openings and each having a bulged port-ion, said frame sheet having inwardly projecting flanges off-set from said bulged portion, and a glass panel seated against said off-set inwardly projecting flanges, the lining sheet having at one side of the opening, a seat for the glass panel opposite the adjacent off-set flange of the frame sheet, of a retaining strip at the opposite side edge of the opening in the door, said retaining strip having a part entering between the bulged portions of the frame sheet and lining sheet and also'having a portion projecting beyond the free edge of the lining sheet and bearing against the inner face of the glass panel opposite the bearing of the adjacent off-set flange of the frame sheet against the outer face. of said glass panel.

2. In an oven door, the combination of a frame sheet having an opening, a lining sheet having an opening, said frame and lining sheets being bulged outwardly and having straight walls forming said bulged portion, said frame sheet provided at the free edges with outwardly projecting flanges and with off-set flanges projecting inwardly from said outwardly projecting flanges, a glass panel seated against said inwardly projecting offset flanges, the lining sheet having a member at one side of the opening in the door constituting a seat for the glass panel, and a removable retaining strip at the opposite side of the opening in the door and comprising a member inserted between the parallel walls of the bulged portions of the frame and lining sheets and said retaining strip having a member projecting at an angle from the free edge of the adjacent lining sheet and bearing against the inner face of the glass panel opposite the adjacent off-set flange of the frame sheet.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
