26 Claims.

This invention appertains to broilers, and more particularly to an electric broiling attachment for a serving platter or a cooking device, such as an electric roaster.

One of the primary objects of my invention is to provide a broiler attachment, which can be associated with a food-receiving member or a cooking device of'ordinary form in such a manner that not only will the food be broiled in an appetizing manner, but smoking and spattering will be reduced to a minimum;

Another object 01' the invention is to provide an electric broiling device, which allows a thorough ventilation of the appliance, so that escape of steam and the like is permitted, whereby radiant heat} is utilized to bring about the searing or the food without baking or steaming, and whereby the fond will be broiled similar to food broiled over an open camp flre.

' Another salient object of the invention is to provide an electric broiling device inwhich the food is visible during. the broiling process, whereb'ylithe food can be turned and removed from ,theifljloilel at the desired advantageous time.'

Another salient object of. the invention is to provide novel means for supporting the reflector and the searingelectrical unit, whereby the reflector and unit-can be quickly swung back to an inoperative out-of-the-way position to permit the convenient placing, turning, and removal of the meats and the like from the platter or cooking rack shelf, as the case may be. a

A iurther object oi the invention is to provide a novel reflectorof such a shape that the heat rays rising from the top of the resistance coils are reflected down on the surface of the rneat near its outer edge, where the direct raysfrom the coils are beginning to diminish in intensity, so that an even distribution of heat over the entire broiling area is obtained.

A further important object of the invention is to provide an electric broiling attachment embodying a novel reflector, an electric resistance unit extending longitudinally thereof, and novel supports for the reflector and unit, whereby the same can be conveniently associated with a roaster and supported in the desired manner thereon, both in its operative broiling position and its inoperative meat+handling position.

A further salient object 01' the invention is to provide a novel handle for the swinging or free end of the reflector and heating unit, whereby the same can be conveniently manipulated, the handle forming means for engaging one end or vention con ists in the novel construction, ar-

Figure 15 is a fragmentary, detailinner end elevation of the center rib; and

Figure 16 is an enlarged, detail, longitudinal sectional view illustrating the means for detachably associating the end of the rib remote from the handle with the reflector.

Referring to the drawings in detail wherein simil r reference characters designate correspon in g parts throughout the several views, the letter A, generally indicates the novel broiling appliance'and R an electric roaster with which the same can beassociated.

While the broiling appliance has been shown associated with an electric roaster, it is to be understood that the same can be utilized with other cooking devices, serving'platters and the like, although, as shown in Figures 1 to 9, inclusive, the appliance has been primarily designe for use with the roaster.

The roaster R forms no part of the present invention, and is of the type now, in general use and known to the trade a Nesco Roastmaster and hence the same will not be described in deis flanged and shouldered, as at I2, to form a seat for the cover. v

The novel broiling appliance A includes a longitudinally extending, centrally disposed rigid rib or backbone member l5. This rigid center rib is preferably formed from sheet metal of the desired gauge, and is of a substantially U-shape in cross-section for the majorportion of its length. Thus, the same embodies a flat bottom wall I! and flaring side walls II. The outer end of the rib is provided with an extension II, the side and resistance unit swung back angularly disposed plate 2| on which is formed the substantially vertically disposed abutment hinge plate 22. The extreme lower edge 01' the hinge plate 22 is rolled to provide a hinge barrel 23. The angle plate 2| is utilized for the purpose of carrying the electric plug 24, which can be of, the two-prong variety [or receiving the socket of the connecting cord ordinarily employed for the roaster.

Associated with the outer end of the rigid center rib isthe hinge wire or supporting foot 25. This supporting foot or hinge wire includes spaced parallel vertical lengths 26 connected at their lower ends by an offset horizontal length or bar 21. The upper ends of the vertical lengths have formed thereon inwardly directed arcuate arms 28, which are connected by a U-shaped cross-bar 28. The cross-bar is received within the hinge barrel 23, whereby the rib can be swung on the hinge wire or foot 25.

The hinge wire or foot is braced at its point of connection with the rigid center rib by a crossplate 30,. This cross-plate extends in rear of the hinge wire and forms a stopll to limit the swinging movement of the center rib on the hinge wire orioot. It will be noted that the foot is disposed in the path of the stop plate 22 of thecenter rib when the center rib is swung to a raised position.

The center rib is utilized for supporting the novel reflector 32 and the electric resistance searing unit 33. The electric resistance or searing unit 33 includes a coiled resistance wire 34, the ends of which are electrically connected to the terminals of the plug 24. The coiled resistance wire is preferably arranged in spaced parallel longitudinal runs on opposite sides of the rib, and

these spaced parallel longitudinal runs are threaded through openings formed in the terminals of porcelain or other insulating blocks 35. These blocks extend transversely across the rigid center rib and have formed thereon upwardly extending lugs 38, which extend through slots 31 formed in the bottom wall of the rib. All of the lugs 36 are provided with longitudinally alined openings, and a holding wire 38 is inserted through the openings in engagement with the upper surface of the bottom wall of the rib.

The rib can have struck out therefrom at one end a lip 39 for limiting longitudinal movement of the wire 38, and the rib adjacent to its other end can have struck out therefrom a bendable tongue 40 for engaging the other end of the wire. This effectively holds the wire 38 in position and the insulating blocks against displacement.

The reflector 32 is preferably formed from sheet metal and can be chromium-plated to give a good reflecting surface and to prevent tarnishing. This reflector extends substantially the full length of the rib and has formed in its longitudinal center a dovetail-shaped guideway ll to receive the rib. Thus, the reflector can be easily and quickly slid on and off the rib, which allows the convenient and expeditious cleaning of the reflector when necessary or desirable. On each side of the guideway 4| the reflector is provided with longitudinally extending arcuate heatreflecting wings 42, and these wings form an important feature of the invention; as will be later set forth.

adapted' to engage the roaster, as will be later set forth.

By pressing the arms 45 together the attach-- ing feet portion can be snapped under the tongues it formed on -the outer end of the rib, and this permits the convenient association and rigid connection of the handle with the rib.

In conjunction with the broiler, a broiling rack 50 can be placed within the roaster or other cooking appliance. This rack includes inverted U-shaped end portions or handles the lower ends of which are connected together by longitudinally extending wire strands 52. The longitudinal strands 52 can be braced by transversely extending wires 53.

The end portions or handles 5| carry a series of hooks. 54 from any of whichthe broiling shelf 55 can be' suspended. This broiling shelf is also preferably formed from wire, and the end strands thereof can have struck up from the same loops 56 for engaging over the selected pairs of hooks 54,. By this arrangement the shelf can be placed in the preferred location relative to the electric resistance element.

'In use of the improved appliance, the wire rack 50 is placed within the roaster R, as clearly shown in Figures 3 and-8. If preferred, the rack 'can'be provided with downwardly bent legs 5]! for engaging the inner pan of the roaster.

The broiling appliance A is now associated with the roaster by inserting the hinge wire or supporting foot 25 within/ the roaster between one end wall thereof and one end portion of the rack. The side wires 28 of the supporting foot closely engage the side wires of the adjacent end portion of the rack, and the offset part 21' of the foot extends across the adjacent end portion of the rack. The arms 28 of the foot will res upon the shoulder l2 of the roaster.

With the handle 43 connected to the appliance as shown in Figures 1, 2 and 3, the bracket portion l'l thereof will engage the shoulder l2 of the roaster at the opposite end thereof from the arms 28. This effectively holds the heating element or resistance coils II and the reflector 32 in the desired proper position relative to the rack and broiling shelf.

Obviously, by grasping the cool grip ll of the handle I! the resistance element and reflector can be swung back on the hinge wire to a raised elevated position to permit the placing of the food to be broiled on the rack, the turning ofthe food, and theremoval of the food from the shelf after the desired broiling action has taken place. Y

when it is desired to clean the broiling appliance the handle 43 can be removed from the rigid center rib II by pressing the feet 46 together and sliding the same from under. the tongues I! of the rib, after which the reflector 32 can he slid off said rib. It is to be noted at this point'that the insertion of the reflector I2 is limited on the rib by the flared portion 20 thereof, which forms abutment shoulders 20'.-

Particular attention is invited to the fact that the resistance coils 3| and the reflector are held in a raised elevated position above the roaster and the broiling rack. This has a particular advantage, namely, it allows the observation of the foodbeing broiled. Thus, the food can be turned exactly at the desired time and removed from the shelf at the correct time.

Likewise, a thorough ventilation of the broiler and roaster is assured; which permits the carrying of! of the steam and other objectionable heated air. Thus, the meat or other food is only subjected to direct heat rays, which brings about the proper broiling of the meat or food without stewing or roasting. As steam and the like is carried off, no smoking will be had, and the grease dropping to the bottom of the roaster pan will be cooled, and thus no spattering takes place.

The entire electric broiling appliance closely simulates broiling over an open camp flre in view of the ventilation mentioned above, and thus the food retains its juices and flavor.

The hinge connection between the center rib,

"which carries the reflector and the heating element with the hinge wire or supporting foot, likewise forms an important feature, in that the reflector and heating element can be swung to the raised inoperative position to permit the handling of the meat. If it were not for this hinge the operator would have to remove the broiler and would not have any place to lay it, and, of course, it would be hot and represent a fire hazard.

. As brought out above, the meat or other food is only subjected to the radiant heat from the resistance coils, and the novel shape of the reflector reflects the rays from the top of the "coils down around the edges of the meat at the exact point where the direct radiant heat is diminishing in temperature. intense even temperature throughout the entire broiling area.

From the foregoing description it can be seen that an exceptionally simple and effective broiling attachment has been provided for electric character B. The broiling attachment B is particularly designed for use in connection with a serving or sizzling platter P, but, obviously, the broiling appliance can be effectively used with other similar devices.

As illustrated, the serving on sizzling platter P comprises. a supportingbase or frame 50, which detachably supports the platter body 6|. The ends of the base or frame 60 carry handles 62, which can be provided with sockets 63.

The broiling appliance B includes a. longitudinally extending rib 64, which is similar in construction to the rib I5, and this rib supports the electric resistance element in the same manner as the rib II. The inner end of the rib has formed thereon a cup-shaped member it for receiving any preferred type of plug 61, so that an electric appliance cord 68 can be connected, with the resistance element 65, it being understood that the resistance element is operatively'connected to the plug. The upper outer edge of the.

Thus, the meat is subjected to an -thereofofiset cam-shaped slots 12, and the use of these slots will also be later described.

Detachably associated with the rib 84 is the reflector l3, and the same is provided with a longitudinally extending center channel 14 for receivingthe upper edges of the side walls II of the rib. The reflector, in this instance, is in the shape of an oval cover, but it is to be noted that the same includes arcuate heat-reflecting sides or wings Ii.

The innerend of the cover has formed therein an opening I6, through which the cup 06 is adapted to protrude. By placing the rib at an angle to the reflector, the lip 69 can be placed through the opening 18' and on the upper surface of the reflector, and when the rib is swung to a horizontal position the upper edges of the rib will ride into the central channel ll of the reflector.

Means is provided for detachably locking the end of the rib remote from the cup 60 to the reflector. In the present instanceQthis means includes the handle 11 for the reflector. The bandle can beformed from composition or any other desired material, and has anchored in its lower face a depending stud 18, which is adapted to extend through the reflector. A bearing washer 19 is placed on the stud between the handle and the reflector. The lower portion of the stud, which protrudes through the reflector, is preferably of a polygonal shape in cross-section, and has firmly fitted thereon a double-ended latch lever III. A hearing washer 8| is placed on the stud between the reflector and the latch lever. A screw 82 can be threaded into the stud for holding the latch lever ill against accidental displacement.

and the lever is so disposed that when the manipulating handle is turned parallel with the longitudinal center of the reflector, the ends of the latch lever will ride into the cam slots I2 and flrmly lock the reflector and rib together. By turning the handle TI at right angles to the longitudinal center of the reflector, the ends of the latch lever will ride out of the slots, and thus permit the swinging down of the rib relative to the reflector, so that the reflector and rib can be separated.

' appliance B can be swung to an elevated position on the sizzling platter by grasping the handle II and lifting up on the reflector. Theend of the bracket 83 serves as a stop member for engaging the U-shaped supporting bracket 85 to limit the upward swinging movement of the reflector.
