8 Claims. (Cl. 99-447) This invention relates. to improvements in broiling apparatus especially intended for" use in ovens similar to that which form the subject matter of the application of Marc Resek, et al., Serial No; 20,784, filed April 13, 1948.

In .the convertible oven or" the former'c'ase, as in the oneherein disclosed in connection with the present invention, there is a so-called flowcontrol element or deflector that" is shiftable from one position to another in. the conversion of the oven.

An object of the present invention is to provide abroiling apparatus by. which low-temperature broiling, a method that is very desirable and advantageous forv many reasons, may be performed in a highly satisfactory manner.

Another'object is to provide broiling equipment which supports the food in such a way, and in such relation to the source of heat, and which distributes the heat in such mamier, asto broil the food on both sides simultaneously-and uniformly, thus saving the time and trouble ofturnin the food, and making it unnecessary. to open the oven door during a broiling'. operation, "the door preferably including a window through which the food may be observed'from time to time and progress of the operation followed;

As is customary, a broiler drip pan constitutes a part of the equipment; and another objectoi the invention is to so direct and control the flow of heated fluid through the oven during the broiling operation as to prevent said pan from becoming overheated, thus. avoiding smoke'and disagreeable odors, as well as preventing grease in the pan from catching fire, and the consequential burning of the food-from this source.

The foregoing objects and advantages, with others hereinafter appearing, are attained in the embodiment of the invention illustrated in the accompanying drawings wherein Fig. 1 is a fragmentaryside elevational view of-a cooking range with parts broken away to show the convertible oven in vertical section and conditioned for a broiling operation; Fig. 2 is a similar sectional view. through a part'of the oven, showing the oven conditioned for baking, heating, etc.; Fig. 3 is a fragmentary perspective view of the range, showing the broiling equipment partially withdrawn from the oven; Fig. 4 is a sectional detail, substantially on the line 44 of Fig. 1, and on a scale considerably enlarged over that of the latter view,- the present figure being somewhat in the nature of a diagram, parts beyond the plane of section being omitted; Fig. 5 is a plan view of the broiler grid and burner, showing approximately the relationship between the grid and Like reference characters designate lil ze p'artsin the several views of the drawings.

l denotes, generally, a range body-that' em. closes, with other compartments, a convertible oven compartment 2. This compartment is. defined by a top wall 3, side walls 4, a rear wall 5, and a bottom wall II that appears only in Fig. 3. The open front of the compartment 2 is normally closed by a door-G. A flue l surmounts the top wall 3 and extends therealon from near the front end of said wall rearwardly to the usual vent passage (not shown), the compartment communicating with said flue through an opening 8 in the top wall adjacent the front end of the latter. The rear and side walls mergewith the top wall through curved portions of consid erable radius to aid in cleaning the oven. In the foregoing respects, the present oven is substantially the same as the construction disclosed in the previously mentioned application Serial No.

In the present construction there is, desirably, a second outlet opening 9, located in the central top portion of the rear wall 5. This opening communicates, through a short fiue it, with the previously mentioned vent passage.

Situated in the lower rear part of the oven compartment 2 is an elongated gas burner [5 (Figs. 1, 2 and 5), the same being connected in the usual way with the pipin of the range and havingthe supply of gas thereto controlled by the customary manual and thermostatic valves. Also, the usual flash tube and pilot are provided for initially lighting th burnerand. for relighting it in the action of the thermostat, all of which will be readily understood by those skilled.

in the art. These features are omitted from the drawings as they constitute no part of the present invention and would tend to confuse rather than clarify the reading of the drawings as they pertain to'the invention at hand.

Suitably secured to the side walls e of the oven compartment, in the same horizontal plane, are guides (the one on the right hand side of the compartment being shownin the drawings and designated 20). These guides slidably support a deflector 2|. Perspective view of the de- 3 fiector, and one of said guides, constitute Figs. 6 and '7, respectively. Supported across the front of the oven compartment, with its top flange resting upon and attached to lugs- 22, that are desirably formed integral with the guides 20, is

a front member or channel 2 having, in its web,

a slot through which may extend a tongue 26 that is suitably fastened to the front end of the deflector 2|. I-Iingedly connected to the end of said tongue remote from the deflector, is a handle 21, having a ring 28 pivoted to its free end. The tongue 26 and handle 21 are formed of sheet metal, and material struck fromthe respective parts provide stops 3!) and 3|, the for mer serving, by engagement withthe inner side of the web of the channel 24, to limit the forward movement of the deflector, while rearward movement thereof is arrested by contact of the stop I I 3| with the front surface of said web.

The portion of the oven compartment below the plane of the front member or channel 24 is set off from the space thereabove by a panel 35,

shown as carried by and between depending flanges of the guides 20. Removably'supported by the front member ,or channel 24 and by rear top flanges 38 of the guides 20 is the oven bottom plate 40, which is similar to the corresponding element of the'oven construction disclosed in the before-mentioned application. Said bottom plate is positioned in a lateral 'direction by the side walls .of the oven, and in a direction at right angles thereto by stops 42 wherewith its rear edge engages. These stops are secured to and rise from the flanges 38 of the guides 20 and extend inwardly a distance theretor and is engaged by the rear edge thereof and thrown to and held in a forwardly and upwardly inclined position, as shown in Fig. 2, when the deflector is shifted to its rear position, or that which it occupies when the oven is conditioned for baking or other similar operations, under which circumstances the broiling equipment is removed from the oven. When the obstructer is in the last described or effective position, as shown in Fig. 2, it prevents the broiling equipment from assuming broiling position in the oven. In fact, under this circumstance, the broiler equipment protrudes from the front of the oven and prevents the door 6 from closing.

So-called rack guides are removably supported in the oven compartment adjacent the side walls thereof. These rack guides form the subject matter of a separate application, Serial No. 124,158fl1ed by us on the 28th day of October 1949. It may here be explained, however,

1 that each rack guide is fabricated of heavy wire or rod-like elements that are welded together and each guide includes a rearwardly and upwardly inclined bar 5| and horizontal bars-52 that are suitably spaced above the bar"5|'. The

grid 55 and a broiler pan 56. The pan is deeper .a depth below the plane of the deepest part of the pan,'so that when the pan is placed upon a supporting surface, the marginal portion 5'! is parallel thereto, while any liquid in the pan will collect in the front portion thereof. It may be explained that the flanges and El extend the full width of the marginal portion 51, and that the back flange is notched to accommodate the bars 5|; and so as to extend beneath said bar for engagement with the stops 53.

The broiler grid 55, in its present preferred form, is made from a single piece of sheet metal, and it includes an elevated food support of about the same outline in plan as the depressed portion or sump of-the broiler pan 56. .said food support includes a peripheral wall 56; and a base flange 6!- flares outwardly-from the lower end of the wall 66 and is adapted to bear upon the marginal portion 5! of the pan when the broiler equipment'is in assembled condition: Lugs 68, that arestruck from the flange 61, lie in the plane of the peripheral wall 66 andengage the inner side of the marginal wall of the pan 56 so as 'to hold the grid 55 in position thereon. The peripheral wall '66 ,joins, through an upwardly and.

' edge ofthe base flange 61, to a-height well above the plane of the grill 15, is a shield 16., Aspreviously explained, the oven is illustrated in Fig. 1 in condition for-"broiling, with the deflector?! in forward position where it is located by the engagement of the stop 30 with the inner side of the web of the front channel 24, this having been accomplished by grasping the ring 28 and pulling the handle 21 forwardly through the slot 25, as indicated by legend appearing on the front of said channel. With the deflector in its forward position the obstructor 44 is retained by gravity in ineffective, substantially vertical, 'position. Accordingly nothing interferes with pushing the broiler equipment inwardly along the bottom bars 5| of the opposed guides 50 1mm the rear flange 6| of the broiler pan engages the stops 53.

Assuming that the grid is in position on the I broilerpan, and that the food F hasbeen placed upon the grill 15, and, further, that the burner has been lit and the door 6 closed, the broiling operation proceeds. Heat from the burner rises within the rear of the oven and spreads forwardly throughout the top portion thereof, passing over and about the shield 16 and impinging upon the food F. A part of the heat passes downwardly about and beneath the food through the slots 'H and along the channels formed by the upwardly arched bar-like parts of the'grill between said slots. Thus, the heat has access to substantially theentire surface of the food simultaneously :and broils it uniformly on. both sides without the necessity of turning the food over. Obviously, the shield Hi becomes quite hot duringa broiling operation by reason of its proximity to the column of products rising from the burner; and-it is further .evident that, as a consequence thereof, due to the continuity of the parts, considerable heat is conducted from the shield to the under side of the food byway of the" rear portion of the base flanged! and the, bar-like parts of the grill, thus enhancing the broiling operation. The progress of the broiling operation may be observed through the window in the door 6, it being mentioned in passing that the oven is desirably equipped with an electric light (not shown) in accordance with modern practice. Juices and greases from the food drop through the slots H into' thepan 56 and accumulate in the'lower portion thereof, remote from the source of heat, and the pan is prevented from becoming hot enough to cause smoke and resultant odors by reason of its being shielded from the intense heat of the burner by the deflector '2! and'the bottom 49. V When the broiler equipment is partially Withdrawn from the oven, as in Fig. 3, for the purpose of placing food on the grid or removing it therefrom, the broiler pan and grid are prevented from tilting forwardly by'stops fil (one of which is shown in Fig. 9) that are disposed beneath the bars 5| of the opposed rack guides 50. These stops, in the present instance, are provided by notching the rear fiange SI of the broiler pan at the upper corners of its oppositeends for the accommodation of the bars 5i.

In order to place the oven in condition for baking or similar purposes, as illustrated in Fig. 2, the broiler pan and grid are withdrawn from the oven, and the handle 21 is lifted and pushed in through the slot 25 in the front channel 24, according to the instructions appearing on said channel to the right of said slot in Fig. 8, thereby to shift the deflector 2| to the rear until its movement is arrested by the engagement of the stop 3! with the front surface of the channel 24. This, movement of the deflector causes the 0bstructor 44 to be swung to a forwardly and upwardly inclined position, in which it is effective for preventing the broiler equipment from being fully inserted into the oven, thus safeguarding against the error of attempting a broiling operation with the deflector 2! in its rear position. With the broiler equipment removed from the top portion of the oven, a rack of suitable design may be inserted on either the upper or the lower bars 52 of the opposed rack supports; and when either the rack, or the broiling equipment, is not in use, it may be stored conveniently in the bottom portion of the oven compartment below the panel 35.
