9 Claims.

The invention relates to a means arranged for use in a broiler compartment of a range or stove for moving the broiler grid or pan to, and holding same in, different elevations in the compartment.

An object of the invention is to provide a means of the character described, which will be formed as a part of a drawer which is movable into and out of the oroiler compartment and upon 10 which the broiler grid or pan is carried.

Another object of the invention is to provide a means of the character described which requires no mutilation of or attachment to any of the stove members, yet is easily and conveniently operated by means which remains concealed except when the broiler compartment is opened.

A further object of the invention is to provide a means of the character described, in which the operative mechanism thereof is at all times concealed from view and fully shielded from the heat and cooking products in the compartment.

A still further object of the invention is to so design the device that when the grid and pan are removed from the broiler compartment,

the portion of the device remaining in the compartment will be unobstrusive, easy to clean, and permit of the free use of practically the entire space in the compartment.

The invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in the following description of the preferred form of the invention which is illustrated in the drawing accompanying and forming part of the specification. It is to be understood, however, that variations in the showing made by the said drawing and descrip-. tion may be adopted within the scope of the invention as set forth in the claims.

Referring to said drawing:

Figure 1 is a horizontal sectional view taken through a stove broiler compartment equipped with the grid adjusting means of my invention.

Figure 2 is a sectional view taken at right angles to the view shown in Figure l, the plane of the section being indicated by the line 2-4 in the latter figure.

Figure 3 is a vertical sectional view taken at right angles to Figure 2, the plane of the section being indicated by the line 3-3 of Figure 2.

Figure 4 is a detail vertical sectional view of a portion of the lever retaining rack used in the device.

In the embodiment of the invention here described, the means is designed for use in cona nection with a roller supported carrier 2 upon which the broiler pan 3 or other grid element is removably mounted for positioning in or out of the broiler compartment 4. The latter comprises a part of a stove or range and has disposed therein, but not herein shown, a burner or the I like which is usually positioned in fixed relation near the top of the compartment.

The carrier 2, as here illustrated, includes a drawer-like structure 6 formed with a bottom wall 1, side walls 8, and a rear wall 0, the front 10 of the drawer structure being preferably left entirely open so that the pan may be moved into or out or the structure and access readily had to the pan if desired without removing the same from the compartment. Support of the carrier II is by means of rollers ll carried by the former and engaging guides or tracks I! on the bottom of the compartment, and rollers l3 mounted on the tracks and engaged by strips H on the under side of the drawer structure 6. go

Positioned within the structure l and preferably located adjacent the side walls 8, are a pair of movable rests IS on which the pan I is arranged to be supported while on the comet.

The rests extend parallel to said walls, that is 35 from the front to the rear of the structure, and are preferably in the form of strips or plates which may be caused to lie practically flat upon the bottom wall I. Desirably the portions of the wall I underlying the rests l8 are depressed so so that when the latter are caused to lie in the position aforesaid the rests will be coplanar with the portion ll of the wall I therebetween, and form therewith a relatively smooth flat bottom on which the pan may be superimposed. 35

As will be clear from Figure 3, the pan is arranged to be supported on the beaded edges I I of the rests, and the rests are so mounted that such edges may be raised or lowered to thereby move the pan when disposed thereon, to different 40 elevations on the carrier. The feature of having the drawer entirely open at the front in combination with the feature of having the grid rests extending lengthwise of the drawer, makes practical and safe in all positions of the rests, 45 the sliding insertion or withdrawal of the pan into or from the drawer from the front thereof. To afford the desired raising or lowering of the edges l8, the rests are pivotally connected to the drawer structure for movement about a horizontal axis parallel to the side walls, and as here shown such connection is made for each rest by means of a rod l9 fixed for movement with the associated rest and pivotally mounted at one end in the rear wall 9 and at the other end in an s earil formed onafrontalmunberflattbeopm endofthestructure. 'Ihememberflislecured to the bottom and side walls and incidentally provides a reinforcement forthestructm'e. Each of the rods I! is located immediately adjacentthe side walls but above the depressed portion of the bottom wall, and desirably the portion of the rest at the rod is offset upwardly and formed the oilsets will in no way interfere with the proper positioning of the pan upon the bottom wall of rests in any position of the latter.

To rotate the rests about their pivot axes, there is here shown provided a lever 23 conveniently fulcrumed to the bottom wall by a bolt 24 and connected by means oi links 28 to crank arms 21 fixed to the rods, the links for the different rods as will be clear from Figure 1, being connected to the lever at opposite sides of the fulcrum bolt. The lever and links are all located on the under side of the bottom wall. while the arms extend from the links to the rods through slots 28 in such wall. Access to the lever so as to rotate the rests is afforded at the front of the structure where a portion of the lever extends through an arcuate slot 2! formed in the frame member 22. Desirably the exposed end of the lever is provided with a handle or knob ii to facilitate operation thereof by the user.

Means are provided inassociation with' the lever for releasably locking same in any one of a 'selective number of positions so as to thereby cause the rests and consequently the pan to be maintained at the desired elevation. As here shown. such means comprises a segmental rack 32 convenient y fixed to the frontal member on the under side thereof and having a series of spaced stops 33 lying in the horizontal path of movement of the lever. The lever is permitted a' limited vertical movement and the stops It are so positioned that the lever will clear same when the lever is moved horizontally while in raised position. on the other hand, when the lever is released it will drop into position for engagement with the stops so that its horizontal movement will be limited. Preferably the faces of the stops, are inclined as shown in Figure 4 that due to the weight of the pan, the latter tends to move and hold the lever in locked engagement with the stops, and yet at the same time when the lever is moved to elevate the pan, the former will readily slide over the stops.

If desired. the member 22 may be marked to correspond with the stops in order that the operator may readily place the lever in a position required for placing the pan at a desired elevation on the carrier.

It will now be clear that practically all of the parts for effecting movement ofthe broiler grid and for maintaining same in desired position are, with the'exception of the rests, disposed below the bottom of the drawer, are completely shielded from'the interior of the compartment thereabove and particularly so when the rests are in their lowermost position and covering the slots 28. Furthermore, sincethe rests may be positioned to lie flat upon the bottom of the drawer, and in such position form a smooth and practically uninterrupted portion of such bottom, the task of cleaning the drawer is rendered simple and easy andatthesametlmenoobstructionswillbeencountered by the pan whenbeing moved into or outofthedrawer. Agrillllorthelikemay be placed in or upon understood that the term grid or pan, as herein used. is intended to cover any element upon which the article to be broiled is supported. By reason of the fact that the grid rests remain spaced and leave the central portion of the bottom of the drawer unobstructed. in all ositions of the rests, ready access to the pan or the like from the front of the drawer for gripping the same'is considerably facilitated.
