Application August 16, 1946, Serial No. 690,947
Our invention refers to garden grills and it has for its primary object, to provide a simple, foldable grill for convenience in storage and shipment. A further object of our invention is to provide a pair of hingedly connected leg-frames, one of which, at its upper end, carries a handlebar and at its lower end a pair of supporting wheels for convenience in transporting the same from place to place.
A further object is to provide means, at the free end of a pivoted fire box supporting frame, for securely locking said free end to the upper ends of a second leg frame, the said pair of le frames being pivotally connected, whereby the device may readily be collapsed or distended in its assembled position for functioning.
A still further object of our invention is to provide a support for a metallic fire box assemblage, in conjunction with a horizontally positioned frame, the same being provided with air spaces between the fire box unit and horizontal frame slats, to eliminate damage through burning the parts.
A still further object of our invention is to provide a fire box having a bottom grate in the form of a perforated plate, over a bottom opening in the fire box and a transversely disposed slidable drawer thereunder, adapted to serve as a damper and also as an ash tray in conjunction with the fire box, it being understood that an offset fiange about the mouth of said fire box serves as a support for a grid sheet of wide mesh, it being also understood that the horizontal frame carries metallic brackets in engagement with the corners of the fire box flanges whereby the same is suspended.
With the above and other objects in view, which will appear as the description proceeds, the invention resides in the novel construction, combination and arrangement of parts, substantially as hereinafter described, and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claim.
In the accompanying drawings is illustrated one complete example of the physical embodiment of the present invention constructed according to the best mode so far devised for the practical application of the principles thereof.
In the drawings:
Fig. 1 represents grill embodying the the section being indicated by line Figure 2.
a sectional elevation of a features of our invention, l-l of Fig. 2 is a plan view of the same with parts broken away and in section to more clearly illustrate structural features.
Fig. 3 is a cross section of the grill, the section being indicated by line 3-3 of Figure 1.
Fig. 4 is a detailed cross sectional view through the fire box supporting frame illustrating a cleat supported work board, the section being indicated by line 4-4 of Figure 1.
Fig. 5 is a crosssectional view through the horizontal frame particularly illustrating a cleat supported tray.
Fig. 6 is a side elevation of the grill in its folded position.
Referring by characters to the drawings, l, 1, indicates strips of a front leg frame, the said strips being connected by a bottom brace-bar 2 and an upper handle-bar 2'.
A similar rear leg frame includes strips 3, 3 connected by upper and lower brace-bars 4 and 4, respectively. These frames are crossed intermediate therein and connected by pivot bolts 5, 5, to the front leg sections, the last mentioned frame being provided with coaster wheels 6, 6, while the ends of the rear legs rest upon the ground to hold the grill in any desired position.
The upper ends of the frame strips 1 have pivoted thereto parallel strips 7 of the horizontally disposed fire box supporting frame, the said strips being secured by pivot bolts 8, 8. The strips 1 of the fire box supporting frame are connected by transverse strips 9, 9, and also the free ends of the fire box frame strips are further secured by a brace-bar 9, as best indicated in Figure 6 of the drawing. The upper ends of the leg frame 3 are provided with slots H] for the reception of bolts I I, which bolts are carried by the horizontal frame strips 1.
Thus, when the grill is open or distended, as shown in Figure 1, the free ends of the fire box supporting frame, are rigidly connected to the upper ends of the rear supporting le frame 3, forming a tie connection.
The cross strips 9 in conjunction with the strips 1 of the horizontal frame form a pocket for the reception of a rectangular metallic fire box l2 and secured to the corners are metallic brackets l3, 13, as indicated in Figures 1 and 2 of the drawing.
The side walls of the fire box have offset flanges l4 at their upper edges, which flanges engage the brackets, whereby an air space between the associated frame members and the walls of the fire box is obtained.
The frame members, for simplicity in conis pulled. full out.
struction, are all fabricated from wood strips and hence, in such cases, the air vents about the fire box prevent scorching or damage to the parts.
Agrid plate I5 is removably seated upon the fire box flange l4, the same being formed with coarse meshed screen opening for full distribution of heat thereto. The vertical walls of the fire box l2 have extending from their lower edges an inwardly inclined bottom I 2, whichbottom terminates with an elongated air-intakeopening I2" therein. The bottom has secured thereto a grating plate [6 preferably formed with a series of perforations therein through which air is-i-ntroduced into the fuel bed stacked thereover.
