FIRE EXTINGUISHER Filed Oct. 16, 1961 INVENTOR. Spencer \schantz 3,093,193 FiRE EXTlNGUISHER Spencer Craig Schantz, 1116 Lakeside Drive, Glassboro, NJ. Filed Get. 16, 1%1, Ser. No. 145,266 4 Claims. 169-1) This invention relates to a fire extinguisher and has for an object the provision of improvements in this art.

One of the particular objects of the invention is to provide a simple and convenient fire extinguisher of the smother type for extinguishing the glow of charcoal embers as soon as the use has been completed, as in cooking in an outdoor portable grill or barbecue stand.

Another object is to extinguish the tire Without the use of water whereby the fuel can be used promptly again without waiting for it to dry out.

Another object is to increase the life of the grill by shortening the time that it is heated.

Another object is to permit the economical use of a larger amount of fuel and quicker cooking by the recovery of a large part of the fuel after use.

Another object is to provide for prompt cleaning and storage of the grill equipment without waiting for the fuel to burn out and the equipment to cool.

The above and other objects of the invention will be apparent from the following description of an exemplary embodiment, reference being made to the accompanying drawings wherein:

FIG. 1 is a top plan view of a device embodying the invention; and

FIG. 2 is a vertical section taken on the line 22 of FIG. 1.

While the size and shape of the device may be varied widely, the extinguisher illustrated is circular in shape and of a size to fit the presently most usual type of portable grill. It includes a shell 1 which serves as a casing and frame, heat insulating material 2, such as fiber glass, and a heat resistant lifting handle or knob 3.

The fuel 4 to be extinguished is indicated as having been pushed together on the fire base 5 which always includes loose ashes from the fire. The rim of the shell seats in the ashes and forms a substantially tight seal to effectively exclude air from the fuel. The fire base, besides ashes, may include sand, vermiculite, asbestos or the like.

The shell can be easily stamped or spun. It is made of a material such as aluminum, copper, iron or the like which will withstand the heating and cooling without deterioration.

The insulation can be cast, packed, anchored or ad hered (with known heat-resisting adhesives) within the shell. Asbestos or fiber glass pads can simply be wedged into position. Heat resistant cements can be poured in.

tet

it has been found that this device will quickly extinaudit] While one embodiment of the invention has been described for purposes of illustration it is to be understood that there may be various embodiments and modifications within the scope of the invention.

What is claimed is:

1. A fire extinguisher of the smother type adapted to extinguish glowing embers over a bed of soft material, as of ashes in a conventional barbecue stand, comprising a closed shell having a broad top portion, and a thin annular skirt extending down from said top portion and having a thin bottom edge adapted to enter into the bed of soft material to form a seal, and a thick layer of heat resistant insulating material disposed within said shell adjacent said top portion and spaced away from said bottom edge by a distance to allow the bottom edge to enter the bed of soft material and allow ample space below the insulating material for the embers.

2. A fire extinguisher of the smother type adapted to extinguish glowing embers over a bed of soft material, as of ashes in a conventional barbecue stand, comprising a closed shell having a broad top portion, and a thin annular skirt extending down from said top portion and having a thin bottom edge adapted to enter into the :bed of soft material to form a seal, and a thick layer of heat resistant insulating material disposed within said shell adjacent said top portion and spaced away from said bottom edge by a distance to allow the bottom edge to enter the bed of soft material and allow ample space below the insulating material for the embers, said insulating material being loose glass wool.

3. A fire extinguisher of the smother type adapted to extinguish glowing embers over a bed of soft material, as of ashes in a conventional barbecue stand, comprising a closed shell having a broad top portion and having a thin bottom annular skirt extend-ing down from said top portion and having a thin bottom edge adapted to enter into the bed of soft material to form a seal, and a thick layer of heat insulating material disposed within said shell adjacent said top portion and spaced away from said bottom edge .by a distance to allow the bottom edge to enter the bed of soft material and allow ample space below the insulating material for the embers, said top portion having a lifting handle thereon above the portion filled with said insulating material.

4. A fire extinguisher of the smother type adapted to extinguish glowing embers over a bed of soft material, as of ashes in a conventional barbecue stand, comprising a closed metal shell having abroad center-crowned top portion and an annular cylindrical skirt portion extending down from said top portion and having a thin wall and lower edge adapted to enter into the bed of soft material to form a seal, a thick layer of heat insulating material disposed within said shell at the top portion and spaced away from said bottom edge by a distance sufficient to allow the bottom edge to enter the bed of soft material to form a seal and allow ample space below the insulating material for the embers, the insulating material being of glass wool, and a handle for the shell secured on the center of the crown of the top portion.
