25 INVENTOR TONY MALGESINI E355 BY Wm ATTORNEY United States Patent 3,025,848 CHARCOAL BRIQUET SAVER HOODS Tony Malgesini, P.0. Box 17, Tuolumne, Calif., assignor of one-half to Idolo Cimoli, Tuolumne, Calif. Filed Nov. 1, 1960, Ser. No. 66,569 Claims. (Cl. 126-25) This invention relates to improvements in charcoal briquet saver hoods.

The primary object of this invention is to provide a hood having adjustable ventilating openings embodying a structure capable of being placed over burning briquets in a brazier for the purpose of controlling burning, smothering the burning, preventing the blowing of hot ashes, and as a safety factor against contact with the live coals by children and others.

One of the objects of the invention is to provide a light simple structure which can be readily manipulated and which embodies a design which creates with the brazier a pleasing structure. 1

More specifically the invention embodies a hood having an annular body portion formed with a series of spaced ports and an upper truncated conical structure, the hood being associated with an annular damper carried by a band or strap mounting the same on the hood and which band or strap includes ventilating ports which are simultaneously controlled with the ports in the body portion of the hood.

Another object of the invention is to provide a damping device in which air ports are positioned both vertically and laterally of the fire bed of briquets.

A further object of the invention is to associate the parts of the structure so that the ports can be regulated for ventilating purposes or totally closed by manipulation of the single handle.

These and other objects of the invention will more clearly hereinafter appear by reference to the accompanying drawings forming a part of the instant specification and wherein like reference characters designate corresponding parts throughout the several views, in which:

FIG. 1 is a fragmentary elevation partly in section showing the assembly;

FIG. 2 is an enlarged detailed view in section showing the association of the hood and the damper;

FIG. 3 is a top plan view of the assembly;

FIG. 4 is an exploded view showing the parts of the assembly; and

FIG. 5 is a detailed view in section showing the top vents.

In FIG. 1 there is illustrated a conventional brazier body having a bottom wall 1, annular side wall 2 and a fabricated grate 3, these parts being supported on legs indicated at 4. The instant invention is in the nature of a hood and is illustrated in FIG. 4 as embodying a hood assembly having the annular body portion 6, a truncated cover or top portion 7 and a radial bottom flange 8. The annular body 6 is illustrated as being provided with a series of spaced ports 10. The truncated top 7 has its flat upper face 2211 (FIG. 5) provided with an axially arranged upwardly projecting retaining pin 11 and the seat area about the pin is formed with ports or vents 14 as shown in FIG. 5. A pin is also located on the band structure 6 of the hood and radiates therefrom as indicated by reference character 15.

Still referring to the exploded view in FIG. 4, a damper is illustrated for association with the hood and comprises an annular band 16 formed with ports 17 generally corresponding to the ports in the hood body 6, both as to size and arrangement. The band 16 is notched at 18 to provide shoulders 19 forming stops when associated with the pin on the hood. A handle 20 extends vertically of the band and is of such a height that it will, when the parts are assembled, project well above the cylindrical portion 6 of the hood to give access thereto for adjustment of the damper assembly.

An angular supporting strap has its vertical terminal portions riveted to the damper band 16, this supporting strap having its side walls 22 converging inwardly to correspond to the angle of the truncated conical top 7 of the hood structure and the side walls 22 are adapted to overlie this area of the hood. The converging side walls 22 of the damper support are connected by a horizontal portion 23 which is provided with perforations 24 of a size and arrangement to be associated with the perforations 14 in the top of the truncated hood 7, as shown in FIG. 5.

The horizontal portion 23 of the supporting structure of the annular damper is formed with a central opening 23a through which the axially extending pin 11 at the top of the hood projects to hold the parts in proper association and to permit the relative rotation between the hood and the damper. A handle 25 extends across the top of the hood cover 7 and straddles the support portion 23 to facilitate the lifting of the assembly.

Referring now to the enlarged fragmentary section of FIG. 2, the wall 2 of the brazier is shown with the grate 3 supported within the brazier structure. The bed of briquets is indicated at A. A fragment of the present invention is illustrated associated with this brazier assembly and it will be noted that the annular flange 8 projecting laterally from the bottom of the cylindrical hood 6 is mounted upon the grate and provides a trackway for the mounting of the annular damper portion 16. The supporting strap 22 is shown with its vertical terminal portion 22a bent downwardly against the annular damper 16 and riveted thereto by means of rivets 27. This view illustrates the converging arms 22 of the supporting member for the damper as lying flush against the upper conical surface 7 of the hood.

A device constructed in accordance with the foregoing basically is to be placed over the top of live briquets and when so positioned and with the various ports closed will function to smother the fire and save the unburnt briquets for further use. If the fire in the brazier is to be merely controlled so that the heat from the fire can be used later, the ports in the assembly will be appropriately opened to permit the entrance of the necessary air. Basically the concept is the provision of a ventilated hood with controlled ventilation and can be used as a safety factor where children are present and a barbecuing operation has been finished. It further will be useful in preventing hot ashes from being blown out of the brazier which might inadvertently cause the starting of a fire if the device should be unattended and without the protection of a hood. Preferably the device will be made of galvanized steel Or aluminum and of appropriate sizes and with appropriate ventilating openings to accommodate braziers of different sizes and configurations.

What I claim is:

1. In combination with a brazier for supporting and burning briquets, said brazier including a bottom and an annular side wall, a grate positioned in said brazier above said briquets, a hood-like structure for use in encompassing said briquets for controlling or smothering the same, said hood-like structure including an annular body defined at its lower marginal edge with a radially extending annular flange seating on said grate, said annular body being formed with a series of circumferentially spaced ports, a truncated top for said annular body having a flat upper perforated central portion, pin means projecting axially of said upper central portion, an annular damper rotatably embracing the annular body and provided with ports for registration with the ports in said annular body, and a supporting strap on said annular damper including converging side members and a flat perforated top, the perforations in said top of the supporting strap being arranged for registration with the perforations in the fiat upper central portion of the truncated hood when said ports are in registration, said pin means projecting from the upper central portion of the annular body and extending through the flat perforated top of the damper to retain the damper against displacement during its rotation on said annular body.

2. The structure of claim 1 characterized in that a handle member is provided on the truncated top of the hood-like structure, the arms of the handle straddling the supporting strap and being secured to the truncated top.

3. The structure of claim 1 characterized in that the upper marginal edge of the annular damper is provided with a U-shaped slot, the Walls defining the slot co-acting with a pin in the annular body of the hood-like structure to limit the vertical movement of the annular damper with respect to the annular body.

4. The structure of claim 1 characterized in that the converging side members of the supporting strap of the annular damper are formed of flat plates and lie flush on the truncated top.

5. The structure of claim 1 characterized in that the flat perforated top of the supporting strap is seated upon and lies generally flush with the flattened perforated top of the hood-like structure.
