OVEN-DOOR SUPPORT.

Specification of Letters Patent.

Patented Jan. 2, Milt.

Application filed June 17, 1914. Serial No. 845,539.

To all whom it may. concern Be it known that we, l/VILLIAM R. JEA- VONS and ARNOLD R. Wrrrrrnrcnn, citizens of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and use ful Improvement in ()ven-Door Supports, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to ovens, and more particularly to means whereby the doors of ovens may be supported in open position.

/Vhile applicable to doors of other ovens, the invention illustrated herein is shown as applied to the door of an oven for gas or oil stoves. In ordinary practice, the doors are supported in open position by means of chains or rods, the chains or rods being connected at their lower ends to the door and at their upper ends to points adjacent to the upper end of the oven, or to points within the oven. Among the disadvantages arising from the use of the chains is that, in closing the door, they are liable to be deflected outwardly, catching between the door and the oven and preventing the closing of the door; in the case of the jointed rods they are liable to get caught on the center. A further disadvantage in both types is that their ends are liable to become unhooked.

The object of this invention is to provide door supporting means which are free from the objections noted and which combine the attendant advantages with cheapness of construction and ease of assembling and disassembling.

A further obj ect of the invention is to provide a supporting device that may be applied to the outside of a door and serve to support the same from beneath, when the door is in open position; also to provide for this purpose a jointed rod or wire which will be so constructed and the parts whereof will be so arranged as to be braced by the oven front, whereby comparatively light stock may be employed in the parts of the said device and the efficiency of the device be enhanced; also to provide a construction of supporting device that will occupy a mini mum space when the door is closed and one that will not catch on the center as the door is lowered.

Still further and more generally speaking the invention may be defined as consisting of the combination of elements embodied in the claims hereto annexed and illustrated in the drawings forming part hereof, wherein Figure 1 shows a front elevation of an oven having our invention thereon, the door being closed; Fig. 2 represents an enlarged vertical sectional view on the line 2-2 of Fig. 1; and Fig. 3 a detail in perspective of the connection between the supporting device and the oven door. 7

Describing by reference characters the various parts illustrated herein, 1 represents the sides, 2 the front, and 3 the top of an oven of the gas or oil stove type, the oven disclosed herein being of the knock down type and being preferably of sheet metal.

Pivoted to the front is the door 4c, said door codperating with the opening 5. Above the top of the door opening, the metal of the oven front is folded upon itself to form an inwardly projecting flange 6, and its upper end is folded to form a flange at 7 parallel with the flange 6, said flanges constituting a guideway for the oven top 3, the upper wall of the top being inserted beneath the flange 7 and the lower or lining wall 8 being adapted to rest upon the flange 6. The bottom 9 of the oven may be connected with the front in any desired manner, as by means of the U-shaped flange 10 on said wall engaging the U-shaped flange 11 at the bottom of the front. The door is also of sheet metal and comprises generally a foundation plate of sheet metal and an inner lining plate, the bottom edge of the plate being bent into shape to form hinge loops 13 cooperating with similar loops 14- carried by the front 2 to receive a hinge rod 15. The metal at the upper end and the sides of the door is folded upon itself as shown at 16 and 17 to form a closure for the top and sides of the opening 5.

The door plate 12 is preferably bulged outwardly at the central portion, as shown at 18, and the said plate is provided with a liner, the-central portion 19 whereof is projected inwardly to fit within the flange 19 defining the oven opening, the marginal portions 20 of the liner being in substantial contact with the plate 12 and being secured thereto by the flanges 17 (see Fig. 8).

The front of the oven door, below the door opening, is provided at each side thereof with a slot, said slot registering with a similar slot in a backing plate 21. Through these slots there extend the ends of a hinge loop 23, said ends being flanged outwardly,

as shown at 23 whereby each. hinge is firmly supported.

Each hinge 23 supports a link, which is preferably made of wire bent at one end to form a loop 24 having a straight hinge pin when the door is closed, the loop 24; will lie close to the front 2, extending substantially parallel thereto. The upper portion of the link, however, is offset with respect to the lower portion, being bent outwardly, as shown at 26, and is provided at its upper end with a loop 27 which is adapted to receive therewithin the loop 28 at the lower end of the brace rod 29, the upper end of said rod being provided with a loop 30, which is connected to a hinge loop 31 extending through a slot in the oven door and secured thereto by flanges 32 and a segmental plate 33 located within a recess 21 in the outwardly projecting portion 19 of the liner, the parts being connected in the same manner as is the case with the hinge loop 23.

With the parts constructed as illustrated and described the operation will be as follows: When the door is closed, as shown in Fig. 2, the supporting devices will be in their extended position, with the rods or wires 29 extending close to and in substantial contact with the door and the links to which they are connected extending vertically', in line with the said rods or wires, and having their upper portions offset outwardly whereby, as the door is opened, the joint between each linkand its corresponding rod or wire is sufiiciently offset to offer no opposition to the opening movement. When the door reaches a horizontal position, the ends of the loops 28 bear against the lower portion of the oven front. In this position the ofiset portions of the links 26 gxtend substantially parallel with said front ace.

By the construction disclosed, it will be apparent that we have produced an extensible and collapsible oven-supporting device which cooperates with the oven front to form a brace whereby the door may be supported in its open position and one wherein the lower member or link of each device is relieved of the burden of supporting the weight of the door, the thrust on the rods or wires 29 being transmitted almost entlrely against the oven front. In other words, the burden of supporting the weight of the door (and anything thereon) is carried by the rods or wires 29, the links serving mainly to preserve the alinement of the rods .or wires and to form a non-slippingsupport for the lower end of said rods or wires, which bear against the oven front.

Having thus described our invention what pivotally connected to the door and a linkhaving its lower end pivotally connected to the oven beneath the door and having its upper end offset outwardly and pivotally connected to the lower end of the said rod or wire. 7

2. The combination, with an oven having an opening therein, of a door mounted on a horizontal pivot beneath the opening, a rod or wire having its upper end pivotally connected to the door and having a loop at its lower end, and a link pivotally connected to the oven beneath the door and in substantially vertical alinement with the rod or wire, said link having its upper portion offset outwardly and pivotally connected to the loop at the lower end of said rod or wire.

3. The combination, with an oven having a door opening, of a door pivoted to the oven and adapted to swing upwardly and downwardly thereby to close and open the oven, a pair of rods or wires, one of said rods or wires being pivotally connected at one end to the door and adapted to engage the oven beneath the door with its other end, the other rod or wire being pivotally connected at one end to the oven and pivotally connected to the oven-engaging end of the first mentioned rod or wire.

4. The combination, with an oven having an opening therein, of a door pivoted beneath the said opening and adapted to swing upwardly and downwardly thereby to close and open the oven, a pair of rods or wires at'each side of the door, the rods or wires of each pair being pivotally connected, one rod or wire of each pair being pivotally connected to a side of the door and of such length as to engage the oven beneath the opening thereof with its other end when thedoor is open, and the other rod or wire of each pair having an end pivotally connected to the oven.

5. The combination, with an oven having a door opening, of a door pivoted to the oven and adapted to swing upwardly and downwardly thereby to close and open the oven, a rod or wire pivotally connected at one end to the door and of such length as to lOO engage the oven beneath the door with its other end when the door is open, and a second rod or wire pivotally connected at one end to the oven and having its other end pivotally connected to the oven-engaging end of the first mentioned rod or wire, the upper end of the second rod or wire being offset outwardly.

6. The combination, with an oven having a door opening, of a door pivoted to the oven and adapted to swing upwardly and downwardly thereby to close and open the oven, a rod or wire pivotally connected to the door at each side thereof, said rod or wire being of such length as to engage the oven beneath the door thereby to support the door in an open position, and a pair of rods or wires adapted to support the ovenengaging ends of the first mentioned rods or wires, the last mentioned rods or wires being pivotally connected to the oven and to the first mentioned rods or wires.

7. The combination, with an oven having a door opening, of a door pivoted to the oven and adapted to swing upwardly and downwardly thereby to close and open the oven, a rod or wire pivotally connected to the door at each side thereof, said rod or wire being of such length as toengage the oven beneath the door thereby to support the door in an open position, and a pair of rods or wires adapted to support the oven engaging ends of the first mentioned rods or wires, the last mentioned rods or wires being pivotally connected to the oven and to the first mentioned rods or wires, the upper ends of the last mentioned rods or wires being offset outwardly.
