Portable or transportable cooking machines are essential for preparing food at locations where conventional cooking facilities are not available. As an example, làrge picnics, weddings, special purpose meetings, fairs and other special events which require food may be held at locations remote from conventional food processing facilities. For t~lese events, it becomes necessary for a caterer to prepare food utilizing a transportable , .
food cooking machine. With tlliS device fresh food may be prepared on location and the quality of the food greatly surpae~ses that of food which is prepared at one location and thereafter transported to an event at another location.
~ Early portable food cooking machines utilized charcoal as a source of heat. ~n example of such a machine may be seen by referring to U.S. patent number 3,499,380 to Gongwer. In this machine, a conveyor moves food longitudinally within the machine housing over a bed of charcoal. In addition to being expensive, the use of charcoal in such a machine presents a number of significant problems. Because the charcoal requires oxyqen to burn, doors in the sides or at the ends of the machine must be opened to provide a supply of oxygen for the charcoal fire. Such heating is not environmentally controlled~inasmuch as any emissions must pass to the outside of the machine.
"~
~ ~ ,, ; , ~ -~ ~ 2028~74 Starting a charcoal fire also presents problems. Because charcoal requires some time to reach a temperature at which the fire will be self sustaining, it is not uncommon for an operator to apply a combustible material such as kerosene to the charcoal to start the fire. This procedure may be dangerous and entails additional expense in the use of charcoal.
Additionally, charcoal fires present difficult problems in terms of temperature modulation when used in a portable food cooking machine such as illustrated in the Gongwer patent. When cooking with charcoal in such a machine, an operator must raise and lower door panels formed ln the sides and at tlle ends of the machine in order to regulate the air supply to the fire. This makes temperature control inexact and difficult. Also, using charcoal makes it difficult to have different temperature zones from one end of the machine to another. As an example, in such a machine it is desirable to provide heat to a sauce vat at one end of the machine to warm the sauce prior to cooking the food.
Furthermore, for some foods a temperature gradient from one end of the machine to the other provides important cooking advantages.
Further problems in connection with charcoal heated portable cooking machines arise when the cooking process has keen completed and the food product must be removed from the machine.
At such time, the doors must be opened to remove the product.
However, opening the doors increases the flow of oxygen to the fire which frequently causes the fire to flash ~or to flare up.
Thus, great caution must be exercised when the doors are opened 2 ~;
202~674 to remove the product inasmuch as the charcoal fire cannot be extinguished prior to such removal.
Lastly, portable cooking machines using charcoal as a cooking medium cannot be used inside of a building.
Consequently, this limits the usefulness of such machines in very cold or inclement weather.
It is desirable to provide a portable cooking machine having a heating source the temperature of which may be regulated easily, which will allow for different temperature zones within the cooking machine, which may be started easily, which may be operated at low cost an~ wl-ic~ m~y be utiLi7e~ inside of building.

DE8CRIPTION QF ~E PREFE~RED E~BODIMENT
Referring to the drawings, it may be seen that the transportable cooking machine (10) of the present invention has a frame (12) mounted on an axial (14~ which supports a pair of wheels (163 and a housing (17). Housing (17) comprises a pair ~: `.~.
of side walls (18 and 20), a pair of end walls (22 and 24), a bottomiwall (26) and a top wall (28). The walls (18 through 28) of housing (17) define an enclosed cooking space (30). :~
A food conveying means (32~ mounts within the cooking space (30) of housing (17). Food conveying means (32),has a pair of shafts (34 and 36) mounted in bearings (38) at opposite ends of the housing (17). Preferably, the bearings (38) are mounted on :;
4 ;-~
~ . ~.. .....
202867~
the exterior side walls (18 and 20) of the housing to enable the bearings to be serviced easily.
A pair of sprockets (40) are mounted at opposite ends of shaft (34) and a pair of sprockets (42) are mounted at opposite ends of ihaft (36). A pair of continuous chains (44 and 46) interconnect the sprockets (40 and 42). Shaft (34) is drivingly connected to a gear reduction mechanism (48) driven by an electric motor (50). Consequently, when motor (50) operates, shaft (34) rotates clockwise and sprockets (40) drive chains (44 and 46).
A hand crank (52) attaches to the opposite end of shaft (34) to provide a means of driving chains (44 and 46) in the event power would not be available to motor (50).
Food~carrying baskets (54) are pivotally mounted on bars (55) connected at each end to the conveyor chains (44 and 46).
In this~fflanner the conveyor chains (44 and 46) transport the baskets (54) from one end of the cooking space (17) to the other , between the end walls (22 and 24). Turning to Fig. 4 of the drawings, it may be seen that as shaft (34) rotates clockwise the lower runs of the chains (44 and 46) are moved from right to left as viewed in that figure and the upper runs of the chains (44 and 46) are moved from left to right as viewed in that figure.
A sauce vat (56) is mounted within housing (17) adjacent end w~all (22). Movement of the food carrying baskets (54) will now be described. Turning again to Fig. 4, it may be seen that the : ~
~ lower run o~ chains (44 and 46) which transport food baskets (54) ;~ extends horizontally between the end walls (22 and 24). The food ~ 5 ~ 2~867~
baskets (54) are maintained in a horizontal position by horizontal bars (58), partially shown, which lie below the lower run of the chains and the upper run of chains (44 and 46) are maintained in a horizontal attitude by horizontal bars (60) partially shown which lie immediately below the upper run of the chains. When food conveying means (32) operates, the lower runs of chains (44 and 46~ pull Pood carrying baskets (54) from right to left as viewed in Fig. 4 and the baskets are maintained in a horizontal attitude by horizontal support bars (58). When the food baskets reach the sauce vat (56) they slide off of horiæontal bars (58) and pivot downwardly into the sauce vat (56) to become immersed in sauce. Thereafter, the baskets are moved in a clockwise direction around sprockets (40) and are pulled from left to right as viewed in Fig. 4 by the upper runs of chains (44 and 46). Again, the food baskets are maintained in a horizontal position by horizontal support bars (60). It may be observed that in one direction of travel the bottom on the food basket is faced downwardly whereas in the opposite direction of travel the tops of the food basket is faced downwardly. In this manner both sides of the food becomes cooked.
The heating means (64) of the present invention may be seen by referring to Figs. 2 through 4. In the preferred embodiment of the present invention four individual gas heaters (66) are utilized. However, more or less heaters may be incorporated into the machine as desired. Each gas heater (66) has a burner unit (68) which is mounted upon a horiæontal support~ member (70) on one side of the housing (17). Looking at Fig. 3, it may be seen that the gas heater (66). may be mounted on either side of the ;
.,~
~ , ~ . . ~. ~ , - . - . -, ., -8~74 machine ~10). Each of the gas heaters (66) are enclosed within a housing (72) for protection against the elements.
Turning to Fig. 2, it may be observed that a tube (74) having a plurality of upwardly Eacing openings ('~6) mounts on each,burner unit (68). The tube (74) extends from each of the burner units (68) between the housing side walls (18 and 20).
The bottom of the tubes rest against the b;ottom wall 126). Each of the gas heaters (66) also incorporates a fan (73). Fan (78) provides a source of air from outside the cooking space (30) to .
the burner unit (68) and forces tl~e flames across the width of tube (74)- The, flames project out of the upwardly facing opening (76) in tube (74) to provide a source of heat for the food in the baskets (54) within the cooking space (30). Each of the heaters (66) has a thermastat (80) which may be set at any desired temperature. Referring again to Fig. 3, it may be observed that the gas heaters (66) may be placed at various positions along the bottom wall (26). As mentioned previously each of the gas heaters (66) is controlled individually. Thus, :
the heater (66) adjacent the sauce vat (56) may be turned on prior to the commencement of cooking to warm the sauce before I ~:
~1~, food has to be dipped into it. Additionally, depending upon the amount of food to be cooked, one or more of the burners (66) may ~, ` be turned off to prevent overheating the cooking space (30). Of ~; ~ course all of the heaters (68) may be turned off to enable an operator to remove food Prom the machine (10).
Because air for the gas heater (66) comes from outside of the cooking space (30), it is not necessary to provide a source `~
:
` 20286~
of ambient air to the space (30). ~ccordingly, the doors (82) formed within the side walls (18 and 20) to provide access to the cooking space and the doors (84 and 86) formed in the end walls (24 and 22) to again provide access t~ the cooking space (30) may remain in a closed position. In fact, in normal operation, the cooking space (~0) remains entirely closed in much the same way a conventional oven is sealed to thereby cause the food products within the cooking space (30) to be baked as it passes over the heater (66). This arrangement allows the temperature within the cooking space (30) above each heater (66) to be controlled precisely. It also provides an efficient and economical use of fuel as opposed to a charcoal fire which requires an open cooking space.
Referring to Fig. 4, it may be seen that grates (88) overlie the heater tubes (74). A plurality of substantially permanent ;rock type briquettes rest upon the grates (88) above the heater tubes (74). The briquettes (9o) function to impart additional flavoring to the food within the food carrying baskets (54).
~ In order to prevent the possibility of fire flare-ups caused ; by food drippings falling on bottom wall (26) between the grates (88) and migrating towards the gas heaters (66) a removable drip tray (94) is mounted within the housing (17) just below the lower ~i~ run of chains (44 and 46). The drip tray (94) rests upon a pair of parallel spaced lateral support bars (96) mounted between the side walls (18 and 20) and intermediate two gas heaters (66).
Access to the drip tray (94) may be had by raising the door (82) within side wall (18).
'~
--`` 2028674 Because the enclosed cooking space (30) functions like an oven the top wall (28) becomes heated during cooking.
It has been found that a source of hot water may be provided by placing a water tank (98) upon the exterior surfacs of the top wall ~28) of housing (17). The tank (98) absorbs heat from the cooking space (30) since the walls (18 through 28) of the machine (10) are metal. Because the food preparation machine (10) is used in the food preparation business, the machine must be capable of thorough cleaning. Accordingly, the food preparation machine (10) of the present invention is constructed of stainless steel wherever possible. Thus, the side walls (18 and 20), the end walls ~22 and 24), bottom wall (26) and top wall (28) of the machine (10) all are constructed from stainless steel.
Since certain changes may be made to the above-described structure and method without departing from the scope of the invention herein it is intended that all matter contained in the description thereof or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
