9 Claims.

This invention relates to certain new and useful improvements in camp stoves or picnic grills.

It has for one of its objects to provide a device of this character which is so designed as to be readily folded into a compact condition when not in use and just as readily unfolded for use. Another object of theinvention is the provision of a' portable camp stove or grill which is simple, compact and inexpensive in construction, whose parts are foldably interconnected as a self-contained unit andvare not liable to become detached or lost, and wherein those elements thereof constituting the fire-box walls form a protective shield or apron for the grill plate in the folded position of the stove to prevent the greasy plate coming in contact with ones clothes or the upholstery of the vehicle in which the stove may be carried.

Other features of 'the invention reside in the constructio and arrangement of parts hereinafter desc bed and particularly pointed out in the appended claims.

in the accompanying drawings:-

Figure 1 is a perspective view of my camp stove or picnic grill in its folded or collapsed position. Figure 2 is a perspective view thereof inits unfolded or operative position. Figure 3 is an enlarged fragmentary transverse section taken substantially in the plane of line 3-4, Figure 2. Figure 4 is a sectional view, similar to Figure 3, showing the grill in its partially folded condition preparatory to collapsing the frame. Figure 5 is an enlarged cross section taken on line 5-5, Figure 1. Figure 6 is an enlarged longitudinal section taken on line 8-4, Figure 3. Figure 7 is an enlarged fragmentary horizontal section taken on line 1-1, Figure 5. Figure 8 is a fragmentary end view showing a modified connection between the grill plate and the frame.

Similar characters of reference indicate corresponding parts throughout the several views.

This improved camp stove, which has been designed for burning wood, charcoal or like fuel, is particularly intended for picnics, touring and camping trips, and-for wiener roasts and the like. In the preferred embodiment of the invention shown in the drawings, the same is a selfcontained portable unit which can be compactly folded when not in use and which can be readily unfolded'for use, and in its general organization consists of a collapsible frame adapted to be supported upon the ground and including portions which form a trough to constitute a firebox, and a grill adapted to be supported over 1934, Serial No. ll 6,154,

the fire-box and to be compactly folded within the collapsible frame when the stove is not in use.

The frame preferably consists of a pair of collapsible, intersecting leg members or sections 5 II and II which are pivoted to each other intermediate their ends, as indicated at i2, so that these leg-sections may assume the spread, supporting position shown in Figures 2, 3 and 4 or the collapsed overlying position shown in Fig- 10 ures 1 and '5. Secured to the upper portions of the leg sections It, H and Joining them together as a unit, are side walls or tie plates l3, l3 which extend generally in the direction of those sections and which, in the unfolded position of the frame, form a trough or fire-box it, it being noted in Figures 2 and 3 that these walls converge downwardly to form a fire-box of comparatively large capacity, the lower ends of these walls being spaced apart to form a draft opening. I

As shown in Figure 3, it will be further noted that these side walls I! are disposed substantially in a plane adjoining the outer edges of the respective leg sections IO, ll, so that when the latter are folded to the position shown in Figures' 1 and 5, a pocket or compartment I5 is formed between the side walls for a purpose which will hereinafter appear, such pocket being open at its top and bottomsides, and closed at its ends'by the upper portions of the respective leg sections.

Adapted for disposition over the fire-box in the unfolded position of the. foldable frame I 0, II and for insertion into the pocket I! in the folded or collapsed position thereof, is a grill plate I 6 which is so mounted on the frame as to be capable of movement relative thereto to assume the respective positions mentioned. To this end, as shown in Figures 2, 3 and 4, the grill plate, which may be of any suitable construction, is connected to the upper ends of one set of companion leg-sections, say the leg-sections ii, so as to be capable of a combined swinging and linear or longitudinal movement with respect to the leg-frame, the means shown in the drawings for accomplishing this purpose consisting of pivots l1 secured to said leg-sections II and engaging corresponding longitudinal slots l8 in the end walls of the grill plate. In the horizontal or operative position of the grill plate, its free end rests upon the upper edge of the adjoining sidewall l3, and if desired the grill plate may be provided with suitable notches l9 which interlock with such wall, in the manner shown in Figure 3, to prevent its accidental lateral displacement relative to the leg-frame. At its free end, the grill plate I6 has a suitable handle 20 for manipulating it to its respective positions, such handle'also serving as a means for carrying the stove when collapsed, as shown in Figure 1.

By mounting the grill plate in this manner, it

can be readily swung to the position shown by full lines in Figures 2 and 3 to an operative posi- -tion for .roasting, broiling or cooking, or it may be swung rearwardly to anopen, substantially pendant position, shown by dotted lines in Figure 3, to uncover the fire-box I4 and render it accessible for introducing the charcoal or wood and making the fire, after which it may be swung to its operative position. When collapsing the stove for transporting or storage purposes, the grill plate is shifted transversely of the leg frame It, II, to the horizontal position shown by dotted lines at the top of Figure 3, after which it is swung downwardly and inwardly into the fire-box to a position in alinement with the companion leg-sections H, as shown by full lines in Figure 4. While in this position, it is then allowed to slide or drop downwardly through the draft opening formed at the bottom of the fire-box between the opposing lower edges of the walls ll until its'movement is arrested by the outer ends of the pivot-engaging slots l8 abutting against the pivots l1, which position is shown by dotted lines in. Figure 4. The leg-sections l0, II are now folded together to the position shown in Figures 1 and5, in which position the grill plate II is housed in the resulting pocket I! with, the side walls I! constituting,

guard plates or aprons for protecting the greasy grill coming in contact with the clothes of the user or with the upholstery of the car in which the stove is carried. It will be noted in Figure 4 that the handle faces downwardly and upon bodily reversing the collapsed stove to the position shown in Figure 1, the grill-handle 20 faces upwardly and serves as a convenient medium for carrying the stove, the downward displacement of the leg-frame relative to the grill being prevented by the pivot pins II contacting the outer ends of the leg-slots II, the whole making for a very compact unit which requires but little space to store it and which can be conveniently carried about.

In Figure 8, I have shown a modified form of fieicible connection between the grill plate I! and the leg-frame, whereby the grill may be moved to the respective positions heretofore described.

This connection consists of a link 2| pivoted at one end, as indicated at 22, to each of the legsections ll, while its opposite end is pivoted at 23 to the adjoining end of the grill Plate.
