The present invention relates to a reflector oven, and more particularly to a reflector oven which is collapsible or demountable so as to be readily carried by campers, hikers and sportsmen.

'Heretofore reflector ovens have been used by sportsmen, campers and hikers with considerable satisfaction but also with certain disadvantages and inconveniences. Reflector ovens heretofore have not been readily portable nor demountable. The bulk and weight of the reflector ovens thus far available generally has been larger than would be desired by sportsmen, particularly those sportsmen who have to transport the oven by pack.

In accordance with the present invention a collapsible and readily reflector oven is provided which may be folded so as to be stored within a tray which serves to hold the food which is to be cooked, fried, roasted or broiled. This is accomplished by providing a tray which has internal dimensions which are greater than the maximum dimensions of the remaining elements of the reflector oven.

It, therefore, is an object of the present invention to provide an improved collapsible reflector oven.

Another object of the present invention is to provide an improved collapsible reflector oven which is readily stored within the food tray.

Still another object of the present invention is to provide an improved reflector oven which may readily be used for frying food where the heat is to be supplied solely from the underside of the cooking surface.

Still another object of the present invention is to provide an improved reflector oven having a pivoted reflector which may be shifted in position to facilitate certain cooking operations such as basting and turning the food without exposing the users hand to the heat of the campfire.

A still further object of the present invention is to provide an improved collapsible reflector oven which is readily and economically manufactured of stamped sheet metal.

Other and further objects of the present invention subsequently will become apparent by reference to the following description taken in conjunction with the accompanying drawings wherein:

Figure l is a perspective view of the present invention during operation;

Figure 2 is an end view of the invention shown in Figure 1 illustrating the manner in which 2 the top reflector may be tilted to another position;

Figure 3 is a front view of the invention illustrated in Figures 1 and 2;

Figure 4 is an exploded view showingthe components of the reflector oven in collapsed or folded position for storage in the food tray; and

Figure 5 illustrates a modified manner of formin the hinged connection between the reflectors and the side members.

The perspective view in Figure 1- illustrates the manner in which the present invention is employed adjacent to a campfire ll so that the radiant heat therefrom will be reflected by reflector surfaces i2 and I3 to the lower and upper sides of a food tray M. The lower reflector I2 is connected by hinges It and 1'6 to side members H and i8 respectively. Each of the side members I! and 18 has formed therein a horizontal channel for receiving and supporting the cooking or food tray I 1. Thus the. side memher It" is provided with a stamped outwardly extending channel [9, and similarly the other side member I8 is provided with a stamped channel 2|. Suitable pivoted or folding

legs

22 and 23 are provided for the side members I! and [8 respectively.

The upper reflector I3 is provided with a pair of

hinges

24 and 25 which are connected to the

side supporting members

26 and 21. The side supporting members 2% and 2 are pivotally connected to the

side members

17 and 18 by means of stud bolts having

thumb screws

28 and 29. The lower reflector 12 which preferably is formed of a sheet of bright metal may be provided with a plurality of reinforcingri'bs or corrugations iii. The upper reflector l3 similarly may be provided with a plurality of ribs 32.

The arrangement of the components of the reflector oven as shown in Figure 2 is the manner in which the oven is commonly used for baking, roastin or cooking. With the oven arranged in this manner it is possible to roast or bake meat and fish, and to bake bread and biscuits. An oven of this type has been employed for cooking or roasting fish, for roasting meat and fowl and for performing generally such cooking operations as are conducted in the oven of the conventional stove.

If during a roasting operation it is desired to turn the roast or to baste it the top reflector 1'3 may be moved from the position shown in Figure 1 to the position shown in Figure 2 where- 'upon the food is readily accessible for turning or basting without exposing the hands of the operator to the heat of the campfire. It, therefore, is unnecessary to lift or turn the present reflector oven in order to have access to the food on the tray l4, as has been the case in other types of reflector ovens.

Where it is desired to use the reflector oven as a cooking means for frying eggs, meats, fish and the like, the oven is employed in the manner illustrated in Figure 2 where the top reflector l3 has been moved to shield the top surface of the food pan l4 from the heat of the campfire. The lower reflector I2 serves to direct the heat to the underside of the food tray l4 thereby to provide an eflicient frying surface.

In order to collapse or demount the oven so as to be readily transportable, the

wing nuts

28 and 29 are removed from their cooperating stud bolts. The top reflector l3 together with its

side members

26 and 21 is then removed from the lower side members, and its side members are folded inwardly so as to appear similar to the central portion of Figure 4. The tray M then may be removed whereupon the other side members l7 and [8 connected to the lower reflector i2 are folded inwardly. The one side member such as the side member I8 is provided with a hole 33 so that the one stud may project thereto. Thereupon the

wing nuts

28 and 29 are again threaded on to their studs. The one stud and cooperating wing nut 29 as is apparent from the upper portion of Figure 4 therefore serves to hold in position the side members l1 and IS. The

legs

22 and 23 are then folded inwardly as shown. Due to the provision of the channel members l9 and H in the side members H and IS the maximum dimensions of the reflectors are less than the inside dimensions of the tray l4. Thus, the upper reflector may then be placed in the tray 14 together with its inwardly folded

side members

26 and 21. On top of this the bottom reflector 12 together with its inwardly folded side members I! and I8 and the

legs

22 and 23 is placed. The entire collapsed assembly then may be inserted in a suitable bag or container so as to hold the components together and keep them clean.

In the construction thus far shown and de-- scribed the various hinges l5, I6, 24 and 25 have been shown as being of the piano type retained in position by suitable rivets. As will readily be appreciated by those skilled in the art, it is not necessary to employ hinges of this type since the side members may be provided with suitable separable hinged constructions such as that illustrated in Figure 5. It therefore, is to be understood that where the terms hinge or hinges are employed in the specification and in the claims, that they are intended to cover all forms of construction which permit the side members to be folded inwardly with respect to the reflector .members or to be so collapsed that the side mem- ,to employ a bright metal for the reflectors I2 and I3. For economy in manufacture it has been foundconvenient toemploy aluminum alloy or I light gauge stainless steel for the reflectors and for the remaining part of the reflector oven.

While for the purpose of illustrating and describing the present invention, certain preferred embodiments have been shown in the drawings, it is to be understood that the invention is not to be limited thereby since such variations in the construction and in the components employed are contemplated as may be commensurate with the spirit and scope of the invention, set forth in the accompanying claims.
