3 Claims.

This invention relates to a folding charcoal camp stove, and has for an object to provide a stove of this character having two folding combustion chambers to effect intense heat with little fuel when the stove isset up, the arrangement of the parts being such-that the stove may be folded into a small compact bundle for storage or transportation in minimum time and with minimum effort and may be quickly set up for use when desired.

A further object is to provide apparatus of this character which will be formed of a few strong, simple and durable parts, which will be inexpensive to manufacture, and which will not easily get out of order.

With the above and other objects in view the invention consists of certain novel details of construction and combinations of parts hereinafter fully described and claimed, it being understood that various modifications may be resorted to Within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings forming a part of this specification:

Figure l is a top plan view of the stove set up ready for use.

Figure 2 is a front elevation of the stove shown in Figure 1.

Figure 3 is a longitudinal sectional view of the stove taken on the line 3--3 of Figure 1.

Figure 4 is a front elevation of the stove folded.

Figure 5 is an end elevation of the stove in folded condition with the legs in set up condition and showing in dotted lines one combustion chamber and the grill, in set up condition.

Referring now to the drawings in which like characters of reference designate similar parts in the various views, the stove comprises a hollow sheet metal base IU of elongated rectangular formation in plan and fully open at its lower side. Legs II are hinged to the underside of the top of the base near the ends of the base, each leg comprising a substantially U-shaped rod having the upper ends provided with gudgeons I 2' engaged through openings in the wall of the base to permit the legs to be rocked from the operative position shown in Figure 2 to the folded position shown by dotted lines in Figure 4, in which position the legs are concealed within the hollow base.

I4, and the outer side [5 and the rear. side 16 of each chamber extend below the front side i! of the chamber and are supported upon the base so that draft openingsl 8 are formed on the front sides, The outer sides. areprovided at the bottom with horizontally extending hinge leaves I9 through which pivot pins 2 0 carried by struck up loops 2| on the base, are passed, see Figures 2 and3.

All of the sides of each combustion chamber are hingedlyconnected together through the medium of hinges 22, formed by interdigitated loops on the sides through which pivot pins 23 are passed. The pivot pin of one of the hinges of the sides is provided with a laterally extending grip 24 which permits the pivot pin to be removed to permit the chamber to be compactly folded and lowered to the base as will hereinafter be described.

Each combustion chamber is provided with a grate 25 in the nature of a perforated substantially rectangular blank of sheet metal. The grate is hinged to the outer side of the chamber by a hinge 26 so that the grate may be rocked from the horizontal operative position shown in Figure 3, upwardly against the side, as shown by the dotted line position in the same figure to permit folding of the chamber.

When in operative position, the free end of the grate rests upon substantially triangular cleats 26 which are secured to the inner side of the chamber, see Figures 1 and 3.

A grill 2'! is supported on top of the chambers in operative position, and is adapted to be removed and disposed upon the hollow base, see Figure 4, when the chambers are folded. The grill is formed of a single length of rod material bent to provide a plurality of open loops, the closed end of one loop being reversed with respect to the open end of the adjacent loop, while the free ends 28 provide securing pins which are slidably received in eyes 29, see Figures 1 and 3, secured to the outer side of the combustion chamber midway of the ends of the top edge of the outer side. The grill may thus be slid laterally until the securing pins 28 are free from the eyes 29 to permit the stove being folded.

To fold the stove from the set up position 7 shown in Figures 1, 2 and 3 to the folded posi- The stove includes two combustion chambers tion shown in Figure 4, the grill 21 is slid out of the eyes 29 and thereupon the grips 24 of one of the hinge pins of each combustion chamber are grasped and the pins removed. The front side ll of each chamber may now be rocked open so that the grate 25 may be swung upward to folded position against the respective outer side of the chamber. The sides of each chamber are folded together, one upon the other, into two juxtaposed bundles, see Figure 4, and laid upon the grill 2! which has been previously laid flat upon the base It]. The legs H are now rocked inwardly and upwardly to folded position against the bottom of the base. To set up the stove the operations just described are reversed.

From the above description it is thought that the construction and operation of the invention will be fully understood without further explanation.

I claim:

1. A folding charcoal camp stove comprising, a hollow base, legs hinged to the underside of the base near the ends of the base, said legs being foldable within the base and when extended projecting downwardly and outwardly from the baseand bearing against the bottom of the base, a pair of combustion chambers arranged in relatively spaced relation on the base, each chamber being of rectangular formation in horizontal section and having the inner, outer and rear sides extending to the base and below the lower edge of the front/side to provide draft openings, the outer side of each chamber being hinged at the bottom to the base and the sides of the chamber being hinged together to permit the chamber to be compactly folded and lowered upon the base, a grate for each chamber hinged at one edge to the outer side of the chamber and foldable against the outer side of the chamber in inoperative position, cleats on the inner side of the chamber upon which the free end of the grate is supported in operative position, and a grill removably supported upon the tops of both chambers in operative position and adapted to be disposed on the base under the folded chambers in inoperative position.

2. The structure as of claim 1 and in which the hinge connections of the'sides of each chamber comprises interdigitated loops formed on the sides and pivot pins engaged through the loops, one pivot pin of each outer side being provided with an outturned grip to permit the pivot pin being removed to effect rocking open of the outer side for folding the grate.

3. The structure as of claim 1 and in which the grill is formed of a single length of rod material bent to provide a plurality of open loops, the closed end of one loop being reversed with respect to the open end of the adjacent loop while the free ends provide securing pins, and eyes secured to the outer sides of the combustion chambers midway of the ends of the top edges thereof removably receiving said securing pins.

CHARLIE C. STARK.
