FOOD PRESS
_ BACKGROUND_OF T_E INVENTION

This invention is directed to a food press for preheating and placement on top of food items such as, for example, hamburger, bacon, sausages, steaks or chicken breasts, located on a cooking grilll so as to hold the 5 food item down and to cook the top of the food item while the cooking grill is cooking the food item from the bottom. The cooking plate in the food press is provided the retention means to hold some of its weight so that it presses only lightly on the food item being cookecl, when such is desired, when grilling such items as steak. The food press of the present invention is an improved version of the food press described in U.S. Patent No. 4,635~538.
;

Most of the presses which are presently on the market are designed to put weight on the meat, hamburger or bacon in order to hold it down on the grill. Such presses have little thermal capacity and do not supply sufficient heat to accomplish cooking from the top.

SUMMARY OF THE INVENTION

The invention provides a cooking plate for placement on the top of a food produc~ positioned on a heated griddle to press the food product against the griddle, the cooking plate having sufficient thermal mass that when the cooking plate is first heated on the girddle substantially to griddle temperature and thereafter placed on the food product, it supplies sufficient heat to the food product to cook the upper portion of the food product; the food press has a skirt, the skirt having sides and top to ~urround the sides and top of the cooking plate, a handle on the press so that the press may be manually lifted on and off a griddle and manually lifted on and ~ff a food product on the griddle, the cooking plate being movably mounted with respect to the skirt; and detent means interengaging the skirt and the cooking plate to selectively retain the cooking plate up within the skirt and to selectively permit the cooking plate to rest upon a griddle while the skirt rests upon the griddle around the periphery of the cooking plate. The features of the present invention which are believed to be novel are set forth with particularity in the appended claims. The present invention, both as to its organization and manner of operation, together with further objects and advantages thereof, may be best understood by reference to the following description, taken in conjunction with the accompanying drawings.

FIGURE 5 is an enlarged section taken generally along the line 5-5 of FIGURE 4, with parts broken away DESCRIPTION OF THE PREFERRED E~BODIMENT

-~ 20 FIGURE 1,3 and 4 show the preferred embodiment of the food press at 10. Skirt 12 is an open-botto~, generally rectangular structure with rounded corners.
It has top 14 of generally rectangular configuration, downwardly-extendiny skirt sides 16 and 18 and ends 20 and 22. The sides and ends are preferably formed as a unitary structure with top 14 and may be drawn from rolled aluminum flat stock into an open-bottomed skirt structure, as illustrated. The sides and ends terminate . ~ , ' .

Ai~i;

in a plane so that the skirt will rest on the flat top 24 o~ a cooking griddle. The griddle is heated from the bottom and has a temperature cont~ol so that the griddle top is maintained at a substantially uniform temperature,for example 375 F for cooking hamburgers.

Handle 26 is formed with a metallic strap 28 secured to the top of skirt 12. Upward extending studs 30 and 32 are secured to the top of the skirt, and holes in the ends of strap 28 engage over the studs.

Cooking plate 36 is of rectangular configuaration and sized to fit within skirt 12. Cooking plate 36 is a thermal mass. In the preferred embodiment, the cooking plate is solid aluminum of about 1/2 inch thick.
Four studs 42, 44, 46 and 48 pass through openings in the corners of the top of the cooking plate 36. Each stud has a head mounted on a shank of smaller diameter. The shank passes through the clearance hole in the top of the skirt, and the head engages on the top oE the skirt so that the plate can move a limited distance (the length of the shank) up and down within the skirt. The shanks of the studs are sufficiently long that when engaged against the top skirt, the bottom surface of the cooking plate extends out of the skirt. Thus, when the food press 10 is placed upon a griddle, the bottom surface of the cooking rests directly against the griddle top 24. The lower edges of the sides and ends of the skirt rest against the griddle top around the cooking plate. In this condition, the cooking plate is heated by the griddle. For cooking frozen hamburgers, the griddle is controlled so that its temperature is preferably about 375 F.

~ or the cooking of some types of food articles, it is desirable to prevent the full weight of cooking plate from resting on the food article. For example, it is desirable to prevent the weight o the cooking plate from resting on steaks, chicken white meat fillets, or fish fillets. In order to selectively support the cooking plate in a raised position, the cooking plate is provided with support pins 50 and 52 which extend axially out of the ends of the cooking plate. Both support pins are shown in FIGURE 1, while the support pin 50 at the left end of FIGURE 1 is shown in more detail in FIGURES 2, 3, 4 and 5. The support pins respectively extend through inverted J-slots 5~ and 56 which are Eormed respectively in the ends 20 and 22 of the skirt. When the pins are in the long upright leg of the J-slot, for example leg 58 of J-slot 54 as seen in FIGURE 3, the cooking plate can Ereely move downwardly within the skirt, even to the point where the bottom surface of the cooking plate is resting on the top surface of grill 24. In FIGUR~ 3, hamburger 60 is shown as resting upon the grill surface and having the full weight of the cooking plate resting on the hamburger~ In this way, the food press 10 is suitable for use in cooking hamburgers. When it is desired that food materials be cooked without the direct contact of the cooking plate, the cooking plate can be raised and retained in the raised position. This is accomplished by the detent notch 62, see FIGURE ~, at the top and at the side of uprigh-t leg 58. The detent notch is sized to receive and retain the support pin and projection 64 between the detent notch and the upright leg 58 retain the suppor~ pin 50 detented in raised position until its release is desired and manually accomplished In the raised position shown in ~IGURE 4, the cooking plate is held in contact with the top of the steak 66 being cooked on grill 24 with some of its weight held by the skirt. The cooking plate provides heat to cook the steak, but without the full physical load of the cooking plate, the steak is not pressed out so there is no reduction in steak thickness due to excess pressure during cooking~ This cooking mode is also useful in the grilling o fish fillets and chicken white meat Eillets.
The detented position is also shown in FIGURE 5.

In use, the press 10, possibly with several similar presses, is placed on the hot griddle and is heated thereby. ~hen the hamburgers are placed on the grill, press 10 is picked up and placed on top of them with the cooking plate in the released position. The hamburger patties are frozen when they are placed on the grill, but there i~ sufficient heat in the cooking plate 36 to thaw and cook the top half. Since the cooking plate 36 is floating with respect to skirt 12, the cooking plate rests upon the hamburger patties and the skirt rests down on the top surface of the griddle around the hamburgers. The ~hermal mass of cooking plate 36 has enough thermal energy that it will supply sufficient ~.

~2~

heat to thaw the upper portion of the hamburger and cook the top surface of the hamburger so that it seals in the juices. It also has enough thermal energy to continue to impart heat to the top surface to cook the top surface.
If the cooking plate 36 is at least 350 F at the beginning of the cooking, as is preferred, the hamburgers do not need to be turned because sufficient heat is supplied by the cooking plate 36 to cook the top half of the hamburger.

; 10 The surface finish of the cooking pla~e 36 in contact with the food item is important to minimize sticking of the food item. The cooking plate is polishedt hard anodized, coated with vegetable shorting, and heated for an adequate length of time and at an adequate tempeature to achieve the golden brown colored non-stick surface. 575 F is the preferred temperature with a time from 20 to 30 minutes The temperature range starts at the bottom at about 350 F, with a very long time in the furnace, and with increasing temperature the time decreases roughly at a rate such that for every 10 degrees Centigrade increase in temperature, the reaction rate is doubled so the result is achieved in hal the time. The upper limit of satisEactory temperature has not been discovered, but it is above 575 F and below 700 F. The bottom oE the cooking plate 36 is also preEerrably flat so that it can be scraped clean with a spatula or the like so that it can be used for cooking through an entire meal period without the need for specialized cleaning.
