Patented Mar. 24, 1931 UNITED STATES -PATENT OFFICE WILLIAM D. ANTRIM, F GLOUCESTER, NEW JERSEY, vASSIGNOIR. TO ROBERTS & MANDER STOVE COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA OVEN FOR RANGES Application filed February 19, 1930. Serial No. 429,697.

The object of this invention is to provide means by which the door of an oven will fit snugly in the opening of the oven without requiring a machine finish of the parts. The

invention is adapted to the doors of ovens of either gas, electric, or coal ranges.

In the accompanying drawings:

Figure 1 is a transverse sectional plan view of a portion of an oven and a door in the closed position;

Fig. 2 is a vertical sectional View;

Fig. 3 is a perspective View of part of the oven door frame;

Fig. 4 is a perspective view of one of the l5 flexible strips which are secured to the frame; Fig. 5 is a View of a portion of the oven shown in Fig. 1, with a flexible strip extended,

this being the position when the door is open; and

Fig. 6 is a view of a modification of the invention.

Referring to the drawings, 1 is the oven of a gas range in the present instance. 2 is the facing frame, which is at eaclrside and at 2 the top of the oven door opening in the present instance. 3 is the lining of the oven and 4 is the outside metal casing, and between the lining and the casing is non-conductive material 5 in the present instance.

"i0 The particular construction of the oven forms no part of the present invention and may be modified as the demand requires.

The oren door consists of a frame 6, open at the center in the present instance, and in the opening is a sheet metal plate 7, which underlaps the inner edges of the frame. 8 is the inner plate of the oven door. This plate has beveled edges 9, which are offset at 10 as shown, so as to fit back of the flange 11 of the frame. Between the frame 6 and the plate T and the inner plate 8 is a non-conductive lining l2 of any suitable material.

The outer ends of the space occupied by the non-conductive material 5 of the oven struc# '15 ture, is closed b v bending over the lining plate 3. as at 3a and bending the outside plate 4 at 4a. Back of the two bent portions of thc plates 3 and 4 is a metallic strip 13, having threaded openings to receive the screws 14.

These screws pass through a flange 2a of the oven facing frame 2, the two bent sections 3o y and 4a of the oven plates, and into the metallic strip 13, securing the said parts firmly together.

In order to make a tight joint between the door and the oven frame, flexible metallic strips 15 are secured to the sides of the oven frame and to the top thereof, so as to surround the oven door opening. The metallic strips are made as shown in Fig. 4 and each strip 60 has a slotted portion 16, which fits between the flange 2a of the oven and the frame of the oven. The strip 15 is slotted in the present instance at 17 for the screws 14. By slotting the strip, the strip can be placed in position, after the other. parts of the range are assembled, by simply backing-off the screws 14 and forcing the portions 16 of the strip into the space between the body of the oven and the facing frame. The portion 18 70 of the strip is beveled preferably on the same bevel as the portion 9 of the door. The outer end is turned inwardly as at 19 and this portion is arranged to slide against a portion 21 of an inner plate 22 within the body of the 75 oven.

When the door is in the open position, then the strip 15 moves outwardly to the position shown in Fig. 5. IVhen the door is closed the door strikes the strip 15 and pushes it 80 into the position shown in Fig. 1, making a close contact between the door and the strip. The strips are preferably located on three sides of the oven door opening. The oven bottom 23 has a raised flange 24 at its outer 95 edge which comes into close contact with the door when it is in the closed position. This flange also acts to hide the hinge openings in the casing from view. In some instances the flexible strip may be located on the door in im place of on the frame of the oven, as shown in Fig. 6, without departing from the main features of the invention. In this instance the stop 15a is welded or otherwise secured to the inner plate 8a of the oven door.

I claim:

1. The combination in an oven, of a body portion; a fralne in front of the body portion and enclosing the oven opening; screws eX- tending through the frame and into the body 10o portion and holding the frame to said body portion; flexible strlps, each angular in crosssection, one section of each strip having a, beveled face, the other section extending between the frame and the body of the oven and secured to the oven by the said screws; and a door having a beveled surface, which resses against the beveled portions of the exible strips when the door is closed, making a substantially tight t between the oven and the door.

2. The combinationy in an oven, of a body portion; a frame located at the front of the body portion and enclosing the oven opening; screws securing the frame to the body portion; a flexible strip, angular in cross-section, one portion of the strip being slotted to pass over the screws which secure the frame to the body portion of the oven, the slotted portion of the strip extending between the frame and the body of the oven, the other portion of the strip being beveled and having its outer edge turned in; a plate within the oven, against which the turned-in portion of the strip rests; and a door arranged to close the oven opening and having a beveled surface arranged to rest against the beveled surface of the strip, so as to cause the strip to yield and form a tight joint between the door and the oven casing.

3. The combination in a range, of a frame having an oven; a door hinged to the frame at the lower edge of the oven opening; flexible strips located between the two sides and the top of the oven frame and the door to seal the space between the two parts when the door is closed; and an oven bottom plate having a flange extending to the oven frame and arranged so that the door will be in contact with the iange when closed.

WILLIAM D. ANTRIM.
