Description
z~z~
The present invention relates to a device Lor lighting ver~ rapidl~ charcoal briquettes by using natural convection of air.
More particularly, the invention relates to an improved charcoal briquettes lighter which is safe, compact, inexpensive and easy to manufacture, and which permits to obtain in a minimum of time and a maximum of security and money-saving, a certain quantity of white-hot (incandescent) charcoal briquettes.
Up to now, many types of charcoal briquettes lighters have been brought on the market. However, none has really taken over the whole market as it normally would be expected for such an innovation, because every type of charcoal lighter does not solve as a whole the well known problems of those people who.like to cook on charcoal.
The object of the present invention is to provide an improved type of charcoal briquettes lighter which globally answers the needs and expectations of the potential users and presents deinite advantages over all the known devices of the same type.
More particularly, the object of the present invention provide a charcoal briquettes lighter which permits its user, especially the one who likes to eat on his patio, to get very rapidly and without close watch, a good charcoal fire, using only newspaper to light it. In so doing, it permits the user to save on purchase of expensive lighting products which may be dangerous, such as gas, petroleum and even electric device.
In accordance with the invention, the so requested capacity to activate rapidly the combustion of charcoal briquettes, is obtained using a cone-shaped deflector provided at the bottom of the device. This cone-shaped deflector initiates the propulsion of air inside the cylinder, which propulsion creates a strong turbulence, and thus improves the combustion.
~: t~
~z~
The efficiency o~-the~roposed invention is such that the user may obtain, within 15 minutes, 2 or 3 dozens oE white-hot charcoal brique-t-tes, ready for cooking.
Moreover, the device may work in big winds, or without wind, and makes it even possible to light damp charcoal briquettes.
The charcoal briquettes lighter according to the invention is of the type comprising an upright cylinder open at both ends and a supporting grate fixed to the cylinder close to the bottom end thereof.This:Lic~hter ischaracterized in that it further comprises supporting legs extending downwardly at the bottom end of the cylinder to support the cylinder with its bottom end in spaced-apart position above a supporting surface, and a cone-shaped,imperforate deflector centrally positioned under the bottom end of the cylinder to increase the draft of the cylinder when the lighter is in use.
As can be understood, the present invention provides a practical system to light charcoal briquettes.
Users often recriminate against systems which are not very practical.
In addition to its rapidity to light briquettes and its practical use, the device according to the invention is compact,thus making its storage easier; it is light to handle; and it is made in one block, without removable pieces that usually may wear or be lost. Furthermore,the device is safe.
Contrary to most of the other devices already proposed, the device according to the invention has a regular cylinder form, providing an easy transfer of the briquettes from the cylinder to a barbecue grill.
In fact, the efficiency of the cone-shaped deflector, which is the essential part of the invention, is sufficient to avoid the use of a main structure which would also be cone-shaped with a decreasing diameter from 35 the bottom to the top of the cylinder as most of other devices of the same type have.
~l~Zi;;~3 This decreasing diameter form was designed to increase the air circuIation, but has the disadvantage of creating a briquettes jam when the same are transfered from the decreasing diameter structure to the barbecue grill.
It is always pleasant to be able to work with a device when it can be put on a table at arm's length.
The device according to the present invention offers this possibility without damaging the surrounding surfaces.
The invention, unlike the others of the same type, has only one receptacle in which is put pellets of papers, such as pellets made from pages of an old newspaper (usually the equivalent of 8 pages).
The efficiency of the invention is such that it does not require addition of newspaper in order to maintain combustion. For this reason, it is not necessary to have two different compartments in the cylinder of the device, as it is in many patents already granted for the same type of device. Most of these patents have an upper compartment to hold the br;quettes and an other one, at the bottom, to permit the introductlon of additional newspaper. In accordance with the proposed invention, this operation is useless because the initial supply of newspaper is sufficient to start the briquettes. The fact that it is not necessary to add additional newspaper during the lighting process makes it possible to put newspaper and charcoal briquettes in the same compartment of the cylinder.
As the bottom of this single compartment is a few inches from the briquettes holding surface, it is possible to use the device safely on a table. This advantage is also possible due to the efficiency of the cone deflector which enables the whole system to work with the initial newspaper supply.
.9L~Ç~21~:3 The lighting can be made through holes on the cylinder,whichallow aneasy access to the newspaper with a match.
Another advantage oE the deviee aceording to the invention is the faet that it is inexpensive and easy to manufacture. Its basic structural elements are Eew and - easy to assemble.
Finally, a proper use of the invention whieh may be used by all those who like to eook on chareoal, leads to a substantial saving in ehareoal briquettes, in that it prevents from having to use a big quantity of briquettes.
It also prevents from having an overflow of briquettes to faeilitate the ignition process or maintain a sufficient amount of heat, when taking into aceount the faet that the lighting proeess from one briquette to another may lead to an irregular fire radiation, which ean only be compensated by increasing the quantity of briquettes.
The present invention, due to its capaeity to insure a permanent air eireulation in the eylinder, enables to activate the eombustion of the briquettes and to obtain, in a short time, a buneh of briquettes whieh radiate a maximal quantity of B.T.U.'s. Then, it is normal, althoughthisit isnot necessary with the invention, to pile 3 or 4 xows of briquettes inthe barbecue gri.ll. A
single row of briquettes is sufficient to maintain a good cooking temperature, when these briquettes are lit with the eone-eonvected system accordillg to the invention.
The invention will be better understood with reference to the following description of a preferred embodiment thereof, taken in eonneetion with the attached drawings wherein the single figure shows a general perspective view of a charcoal briquettes lighter according to the invention.
The lighter shown in the single figure comprises hollow eylinder 1 made of steel of 26 gauges. This cylinder ~Z~Z3 which has a diameter of 7 inches and a height of 12 inches, is formedfrom a metal sheet, fastened up in 2.
The cylinder 1 has three holes 3 each having a 1" diameter, punched at angles of 120 from each other, so as to be equally spaced apart along the circumference of the cylinder. These holes are used to light a briquette lighting material such as pellets of paper that are inserted into the cylinder prior to inserting the briquettes. The holes are places 3 inches over a supporting grate 4 which is used for holding the paper pellets and the briquettes inside the cylinder. The grate 4 which preferably has a surface perforated at 75~, can be made of 20 gauges steel and is fixed to the cylinder 1 at 2 inches from the bottom thereof.
By strictly observing the above mentioned specifi-cations in manufacturing the lighter according to the invention, maximal efficiency can be obtained for this device~
An air inlet of 1 1/2" is provided between the bottom of the cylinder 1 and the ground. To improve the efficiency of this air inlet and of the whole device, a cone-shaped deflector 10 is provided in the gap where the air is allowed to rush in the cylinder 1 at the bottom thereof. The cone 10 of which the angle ~ is of about 60, gives a way to the air entering the cylinder 1 and generates a pressure. At the same time, -the cylinder 1 draws by air convection the air exactly in the same way as in a chimney.
As aforesaid, the supporting grate 4 is preferably perforated on at least 75~ of its surface to facilitate this circulation of air in the cylinder 1.
~Ihen the paper pellets are lighted and light in turn the briquettes, they fall down to at the bottom of the cylinder onto the supporting grate 4. This also improves the air draft.
~1~21~3 A steel handle 8 of 16 hauges can be fixed to the cylinder 1 to make it possible to transfer the briquettes from the cylinder to a barbecue grill. The steel handle is offset towards the bottom o the cylinder and covered by a heat insuIating material such as a 1 inch wood dowel cut in two pieces 9 that are fixed together by two screws. This steel handle makes it easier to carry rapidly and saEly the incandescent briquettes and to pour them into a barbecue grill.
The cylinder 1 is supported by three legs 5 of 16 hauges, folded towards the exterior of the cylinder 1 in order to ensure stability to the device. On each leg, a bracket 6 is fixed in order to centralize and stabilize the cone-shaped deflector 10. These brackets are made of steel of 26 gauges.
A tray 7 made of 24 gauges steel can be placed under the whole device to hold the falling ashes, to maintain cleanliness and to prevent damaging of surrounding surfaces. This tray may advantageously be provided with a projecting edge 11 to improve its ashes retaining efficiency.
All the parts of the device can be assembed by spot welding 12.
The above described charcoal briquettes lighter was tested. These tests have demonstrated that it works rapidly, it operates by natural convection of air and it requires only pellets made from old newspaper to start the combustion process.
The lighter's cylinder plays the role of a chimney, creating a dxaw effect to activate combustion.
As the initial quantity of burning material is sufficient for the whole process, there is no need to add additional burning material during the process.
The initial quantity of newspaper is placed directly under the briquettes. This also increases the ~1~2~Z3 rapidity of the system.
The cone-shaped deflector at the bottom of the device hastens the flow of air in the cylinder and activate the combustion, thus improving the efficiency of the device.
The holes punched in the cylinder facilitate a rapid and easy lighting of the paper.
