4 Claims. (Cl. 126340) This invention relates to the general art of cooking stoves and ranges, having reference more particularly to improvements in the broiler ovens which usually form a part of such stoves and ranges.

More specifically, the present invention relates to broiler ovens of a broadly known type wherein a drawer, rack or the like that supports the broiler grid or other cooking utensil is slidably mounted in the oven and is operatively connected to the oven door, so that, when the door is opened the drawer or rack is drawn partly out of the oven where the cooking utensil is more accessible, and, when the door is closed, is moved to normal position in the oven.

Door-actuated devices of this type for withdrawing and returning the drawer or rack heretofore employed are more or less complicated and cumbersome; and the object of this invention is to provide a very simple, inexpensive and efiicient broiler oven accessory that will occupy only otherwise unused space in the oven, will present no interference with the opening and closing movements of the door, will present a desirable combination of strength, rigidity and light weight, and can be easily detached from the door to permit full removal of the broiler drawer or rack, when necessary for cleaning the same and/or the oven.

A practical and preferred embodiment of the invention is illustrated in the accompanying drawings, in which- Fig. 1 is a perspective view of a gas range embodying my improvement, showing the oven door fully opened, and the broiler drawer and parts carried. thereby partly withdrawn from the oven Fig. 2 is a vertical front to rear section, showing in full lines the door closed, and in dot and dash lines a partly open position of the door which takes up the lost motion in the drawer withdrawing means.

Fig. 3 is a view similar to Fig. 2, but showing the positions of the parts when the door has been fully opened.

Fig. 4 is a fragmentary side elevation of the broiler drawer and drawer-actuating link, showing the position of the latter when it begins to Fig. 7 is a perspective detail of a stationary cam that lifts and lowers the inner end of the link during the final part of the door closing movement and the first part of the door opening movement.

Referring to the drawings, l0 designates as an entirety a modern type of cooking stove or range, in one side of which is a broiler oven, designated as a whole by H. In the upper portion of the oven is a burner l2 supplied with gas through a manifold l3. l4 designates the top wall of the oven, and IS, the bottom wall. Slidable inwardly and outwardly of the oven is a broiler drawer IS, the side walls of which are equipped, as usual, with spaced ledges ll that support the longitudinal edges of a broiler pan l8, in which latter is seated the removable broiler grid l9. The drawer I6 is slidably supported on the oven bottom l5 through the agency of a pair of

rollers

20 and 2| on each side. The foremost rollers 2| are journaled on the inner sides of a pair of inwardly facing channel bars 22 that are spot-welded or otherwise secured on the side portions of the oven bottom l5, and the rear rollers 20 are similarly journaled on the lower depending flanges of a pair of Z-bars 23 that are riveted at 24 to the lower corner portions of the drawer IS; the arrangement being such that the

rollers

20 and 2| on each side are in the same vertical plane.

25 designates the over door which is hanged at 26 to the bottom member of the usual frame 21 of the front opening of the oven. A spring 28 anchored at its lower end to a fixed member of the stove frame and at its upper end to a curved arm 29, rigid with the door 25, cushions the downward movement of the door and assists its up movement; such a spring in various forms being a common equipment of oven doors.

Describing now those features wherein the present invention mainly lies, on the inner face of the oven door 25 is a short lug 30 which carries a fixed pivot pin 3|, on which pin is mounted the outer end of a straight bar link designated as a whole by 32, and shown in isolated perspective detail in Fig. 6. In its preferred form this bar is of channel shape in cross-section, consisting of a web 33 and rectangular flanges 34 on the longitudinal edges of the web. 0n the inner end of the link the web has an up-turned rectangular extension 33'. In the extension 33' is a slot 35 that extends transversely of the main body of the link, and in the web 33 is a somewhat longer longitudinal slot 36 that at its inner end is continuous with the lower end of slot 35.

Attached to the rear end of one side wall of the broiler drawer I6 is a plate 31, and a short bolt 24' is passed through the upper limb of the Z-bar 23, the plate 31, the side wall of the broiler drawer l6 and the lining carrying the ledges I'I, securely looking all of said parts together. on the top edge of the plate 31 is an upstanding lug 36 located above the top edge of the side wall of the broiler drawer, and in the lug 36 is mounted a shouldered and headed pin 39, as best shown in Fig. 5. The diameter of pin 39 is such that it has an easy sliding fit in the link slots 35 and 36. The link is slightly spaced from the adjacent side of the drawer by a pair of spacing washers 40 and 4| encircling the pin 39 on opposite sides of the web of the link respectively.

The slot 35, when engaged with the pin 39, renders the link 32 operative to actuate the drawer from the opening and closing movements of the door; while the longer slot 36, when engaged with the pin 39, permits the link to have a limited amount of lost motion. This lost mo-- tion of the link is necessary to avoid collision of the forward end of the drawer with the door when opening the latter. To effect the transfer of the pin 39 between the slots 35 and 36 at the proper times, I employ a downwardly and forwardly inclined flat cam plate 42, that lies in the path of the inner end of the link and is conveniently formed as an extension of a top flange 43 on the upper edge of a plate 44. As shown in Fig. 2, this plate 44 has a rear vertical flange 45 that is attached to the rear wall of the broiler oven by screws 46. The front edge of the plate 44 is preferably bent outwardly, as shown at 41, to prevent any collision of the plate 31 therewith during the final part of the inward movement of the broiler drawer.

Briefly describing the operation, Fig. 2 shows the position of the parts when the oven door 25 is fully closed. When the door is opened, as it swings from the full line position to the dot and dash line position shown in Fig. 2, the link 32 moves idly, the longitudinal slot 36 riding over the pin 39 until the latter is at the outer end of the slot. At this time, the inner end of the link has reached the cam 42, and as it slides down the cam, the slot 35 rides over the pin 39, as shown in Fig. 4, and this creates an operative connection of the link with the drawer, so that the latter is drawn out to the position shown in Fig. 3 during the remainder of the opening move ment of the door. When the door is closed, the link positively moves the drawer inwardly until the inner end of the link encounters the cam 42 and rides up the latter. At this point, the drawer has been fully returned to normal position in the oven. At this time, the door is invthe dot and dash line position shown in Fig. 2. During the final closing movement of the door, the link moves idly inwardly, the slot 36 riding idly over the pin, restoring the parts to the full line positions shown in Fig. 2.

It will 'be observed that the link 32 is supported wholly at its ends on the pins 3| and 39, and in its to and fro movements does not contact with or rub against any other parts. This manner of .supporting the link avoids both wear and noise.

The channel form of the link 32 possesses the advantage that it may be made very light, as, for example, by stamping it from sheet metal; and at the same time, it is amply stiff and rigid to avoid bending or bowing when under the thrust strain of pushing the broiler drawer back into the oven.

When it may be desired or required to entirely remove the broiler drawer from the oven for cleaning the drawer and/or the oven, this can readily be efiected by merely withdrawing a cotter pin 48 that is passed through a hole in the outer end of pin 3|, and slipping the forward end of the link ofi said pin.

The mere reversal of these operations reestablishes the operative connection of the door to the link.

I claim:

1. In a broiler oven device of the class described, the combination with a slidable broiler grid :carrier, and an oven door hinged at its lower edge, of a laterally extending pin on a side wall of said carrier. a straight bar link pivoted at its outer end to the inner side of said door above the hinged edge of the latter, said link formed with a relatively short transverse pin-engaging slot at its inner end and a relatively long longitudinal pin-engaging slot communicating with, and extending forwardly from, the lower end of said transverse slot, said link being wholly supported by said door and pin, and means disposed in the path of the inner end of said link operating to raise said inner end during the final part of the closing movement of the door and thereby transfer said pin from said transverse slot to said longitudinal slot, and to lower said inner end during the first part of the opening movement of the door to thereby transfer said pin from said longitudinal slot to said transverse slot.

2. An embodiment of the subject-matter defined in claim 1, wherein the means disposed in the path of the innerend of the link consists of a stationary inclined cam up which the inner end of the link slides during the final part of the door closing movement and down which it slides during the first part of the door opening movement.

3. An embodiment of the subject-matter defined in claim 1, wherein the link has flanges on its longitudinal edges to stiffen the same against bending under the inward thrust of the door thereon when closing the door.

4. An embodiment of the subject-matter defin'ed in claim 1, wherein the link has rectangular flanges on its longitudinal edges to stiffen the same against bending under the inward thrust of the door thereon when closing the door, and the means disposed in the path of the inner end of the link consists of a flat downwardly and forwardly inclined cam plate up which the inner end of the link slides during the final part of the door closing movement and down which it slides during the first part of the door opening movement.
