12 Claims.

' Our invention relates to cooking appliances and more particularly to aremovable broiler-grill cr broiling and frying unit to be used within a roaster or the like.

In roasters known to the art, it has been impossible to broil and fry due to the absence of a' of meats placed within the roaster.

A further object of our invention is to provide means whereby the heating member may be swingably andremovably mounted within the roaster.

A further object of our invention is to provide means whereby a tray may adj ustably be mounted under the heating member and within the roaster.

A further object of our invention is to provide a simple, inexpensive, rugged rack, removable tray, and heating member, which will be sturdy and not easily damaged.

Other objects of our invention will either be pointed out specifically in the course of the following description of a device embodying our invention, or will be apparent from such description.

In practicing our. invention, we provide, in combination, a roaster, a rack having a plurality of tray supports thereon, a heating member comprising a heating element and a heat shield including a cooking surface and a heat reflecting surface, a plurality of hinge portions carried by the heat shield for operative'engagement with the rack. and a suitable tray which may be located on the rack.

Fig. 9 is a view illustrating the method by which the lid may be placed in normal position upon the roaster -with the heater unit and tray stored therein; and

Fig. 10 is an enlarged fragmentary view of the fastening device shown in Fig. 1.

Referring to Figs. 1 and 4, we show a rack l comprising upstanding support members 2, and longitudinal base members 3. An oil-set portion 4 may be located at the upper portion of the upstanding support members 2 and may have a transverse rod 5 which may be used as a ball or handle for lifting and carrying the rack, rigidly attached to the ends of such portions andjoining two end support members. tray-or shelf 8 may be adjustably supported on serpentine tray supportingmernbers l which may be rigidly attached to the inner side of the respective upstanding members 2. As shown in Fig. 4, the tray or shelf I is. in the form of a grill or grid, comprising a rectangular frame and a plusupport 1 and the outward off-set portion 4 and may be rigidly attached to the upstanding support members 2 in any suitable manner.

A- removable heater unit I I, comprising a downwardly flanged heatshield, l3 and a heating ele-- ment 2| may be swingably mounted upon the rack I, about one of the intermediate bars 8, by means of hinge portions l2. The hinge portions l2 may be located at one end of the heat shield l3 and may have located therein an L-shaped aperture which receives the intermediate bar 6. permitting the heater unit II to swing thereon. The other end of the heater unit is adapted to rest directly on the bar 5 at the other end.

The heat shield [3 may have a dished portion I4 therein with an embossed or rim portion I5 about the edge thereof. The top surface of the dished portion [4 of the heat shield l3 may be used as a cooking surface (particularly for frying) while the under portion of such heat shield may function as a heat reflector. An aperture l6 may be located in one comer of the dished portion ll or in any other desirable position to permit the draining of excess juices from the cooking surface. As shown in Fig. 3, the aperture I6 is spaced from the heating element 2| so that dripping of juices or other liquid on the heating element is avoided. A handle II may be rotatably attached to the heater unit ll by means .01 a

Any suitable broiling cylindrical collar l9 to facilitate the operator swinging the unitabout the intermediate bar 6 or removing the heater unit.

The heating element may be removably attached to the under portion of the heat shield l3 by means of a plurality of apertures 32 located at one end of said heat shield and a set screw I8 located at the other end of the. heat "shield and extending through the cylindrical 'eollar IS. The heating element 2| comprises a heating coil 22 and may be provided with a plurality of longitudinal members 23, and a pinrality of transverse members '29. The heating coil 22 may beinsulatedly attached to the iongitudinal support members 23 by means of insuof heating element 2| may have extended portions 3| angularly displaced from the plane of such heating element 2|. These extended 'portions may engage the apertures 32 in one end of the, heat shield II! to aid in rigidly attaching the heating element 2| to such heat shield. An

angular depending bracket 21 may be rigidly attached to the heating element 2| at the opposite end thereof and may have a threaded aperture therein which may engage the set screw i8 and rigidly attach the heating element 2| to the heat shield while the extended portions 3| are located within the apertures 32.

Set screw i8, which has merely the lower portion thereof threaded, may be located within the cylindrical collar it, which. attaches the handle H to the rim portion i of the heat shield l3, and which has only an upper or lip portion thereof threaded. Thus, when the set. screw is not operatively associated with the angular bracket 21 oi. the heating element 2|, such set screw will slide freely within the cylindrical collar i9 without becoming disengaged therefrom. It is, therefore, obvious that set screw IB may be removed from the heating element-2| without becoming disengaged from the heat shield l3,

which, in turnensures such set screw will not become misplaced or lost.v

The heating element 2| may be removed from position. By grasping the handle l1 and swinging the heater unit downwardly, such unit will rotate until the free end thereof will contact the'second intermediate bar 3 and remain substantially in a horizontal position.

The rack in combination with the heater unit ||,'may be operativel'y associated with a roaster 31 as shown in Figs. 6, 7, 8 and 9. The rack I may or may not be used in conjunction with the trivet rack 33 of the roaster 31, as shown in Figs. 7 and 8. While being used with the trivet,

v rack 36 the rack is insertedwithin such trivet the heat shield l3 to permit the operator to clean the heat shield without injuring the heating element by backing off the set screw I8 with one hand, and as such set screw releases the angular bracket 21 the heating element 2| may be angularly displaced from such heating shield with the other hand as illustrated in Fig. 5. To remount the heating element 2| on the heat shield i3 the extended portions 3| of the longitudinal support members'23 are inserted within the apertures 32 and set screw i8 is run down into the angular bracket 21, pulling such bracket and the heating element 2| tightly against the underside of such heat shield. The heater unit comprising the heating coil 2| and heat shield i3 may then be swingably mounted upon the intermediatebar 5 of the rack by placing the L-shaped apertures of thehinge portions l2 about such intermediate bar. In such a position the handle l1 may be grasped and the heater unit may then be swung outwardly until the outer portion of the heat shield l3 contacts the transverse bar 5. While in such a position the heater unit II will remain substantially in a vertical rack and the heater unit ii is substantially on a plane with the opening of such roaster. However, if it is desired to use the master for baking purposes only, theheater unit may be removed from the rack and the broiling tray 3 may be located at the upper portion of the serpentine support 1. A portion of the material to be baked may be placed upon the trivet rack 36 and the balance of the material to be baked may then be placed upon the tray 8. Due to the flexibility of adjusting the height of such tray 3, the location of the upper baking material may be an arbitrary factor permitting the tray Bto be located at the desired position on the support 1,

which will result in an even heat distribution about the upper and the lower baking material.

Then should it be desirable to brown the top of the baked goods, such as a pie or beans,it only becomesnecessary to'replace the heater unit H in its horizontal position upon rack If it is desired to use the broiler or heater unit ii for broiling or frying purposes alone, the rack i may be located within the roaster 31 without the presence of the trivet rack 36. The heater unit may then be swung upwardly into its substantially vertical position and thetray 3 may be located at the desired position upon the serpentine support 1. As will be noted from the drawings, particularly Figs. 1 and 8, the adjacent rod 5 engages the heater unit to retain it in sub? stantially vertical position when it is swung in opening direction slightly past vertical position or dead center. The food to be cooked is then placed upon such tray and the heater unit II is then lowered to its substantially horizontal position and the heating coil 2| then connected to a suitable power supply, not shown.

' Grease spatterings while broiling will be avoid-' ed due to the location of the rack within the roaster 31 ,and the presence of the heater unit I I over the cooking material. The smoking which accompanies broiling will likewise be reduced due to theclearance between the heater unit and the.

the heat radiated from the heating coil 2| and thus increase the operating efllciency of such coil or reduce the time required for a satisfactory broiling operation.

Whenever desired, the upper surface of the recessed portion ll may be used as a grill or cooking surface upon which any desired material may be fried during a broiling operation without reducing the eillciency of such broiling operation. However, it is to be understood that the upper surface of the heat shield maybe used as a grill or'cooking surface without the need of a broiling operation being performed within the roaster roaster.

"iace of the heat shield either simultaneously with such broiling action or as a separate function of the unit.

Due to the heating action of the heater unit I! 'while placed within the roaster 31 the interior' temperature of the roaster will be increased sufliciently to enable it to be used-immediately as a In such a case, the rack I and heater unit lllare removed from the roaster and the trivet rack 31 may be introduced therein, permit- .ting the roast or other-desired material to be placed in such roaster and the cooking thereof done without the necessity of pre-heating the roaster 31.

In storing the rack I and heater member ll while not being used, such rack and heater may be placed within the roaster 31 along with the trivet rack 36. The handle H is then rotated approximately 180 so that such handle will be directlyover the cooking surface of the heat shield l3, as shown in Fig. 9, whereupon the cover 39 may be located in its normal position upon the roaster without contacting such handle II.

It is, therefore, obvious that in utilizing a rack and heater unit as hereinabove described in cooperation with a roaster, such heater unit may be used for either broiling or frying, or both .simultaneously, and the excess heat from the heating element of-such heater unit may be used to pre-heat the roaster, eliminating such requirement before starting the use thereof as a roaster. Also double layer baking with or without simultaneous frying may be accomplished.

Various modifications may be made in the device embodying our invention without departing from the spirit and scope thereof, and we desire, therefore, that only such limitations shall be placed thereon as are imposed by the prior art and the appended claims.
