Definitions

  • a fire kindling device comprising a metal alloy of misch metal and magnesium.
  • the present invention is an alloyed composition of misch metal and magnesium.
  • the misch metal supplies the spark 'for the ignition and combustion of the magnesium.
  • the relatively soft metallic stick is scraped with a knife blade, thereby forming an amount of small shavings.
  • the metallic stick is then struck with a blow causing a generated spark to ignite the shavings.
  • the burning magnesium which is in the temperature range of 2800 F., releases a substantial quantity of heat and will kindle almost any type of burnable material, including wet wood.
  • the heat energy contained in the present device is highly concentrated com-pared with that of the various hydro-carbon type fire starting fluids or solids.
  • the present device is the size of a short pencil and contains energy equivalent to many gallons of kerosene.
  • a second object of the invention is to provide a fire starter composed of a highly exothermic metal alloy.
  • Another object of the invention is to provide a fire starter which is self-igniting.
  • Still another object of the invention is to provide a fire starter which has a very high concentration of heat energy.
  • An additional object of the present invention is to provide a fire starter which is unaffected by moisture or temperature and completely safe from accidental ignition.
  • FIGURE 1 is a perspective view of the present invention illustrating its method of use with a common knife blade
  • FIGURE 2 is a top plan view thereof
  • FIGURE 3 is an end view of a modified cross sectional shape thereof
  • FIGURE 4 is an end view of a further modified cross sectional shape thereof.
  • FIGURE 5 is a perspective view of a still further modified form of the present invention illustrating a handle attached to the end thereof.
  • FIGURE 1 a fire starting device is shown and generally identified by reference numeral 10.
  • the metallic stick 10 provides both the ignition spark and a combustible material.
  • the composition of the stick is a metallic alloy containing varied percentages of misch metal and magnesium.
  • the misch metal which provides the sparking properties of the alloy, basically comprises the rare earth metals of cerium, lanthanum and praseodymium. Misch metal is a common alloy with its most well known usage being in cigarette lighter fiints.
  • Magnesium is a highly exothermic metal which combusts with oxygen to form magnesium oxide in the following exothermic reaction:
  • the magnesium percentage of the alloy can vary from 50% down to .5% and still adequately combust the shavings 12. Compositions of 2% to 20% magnesium and to 98% misch metal have been found to have the most desirable properties. Misch metal percentages over 98% give hardness properties to the alloy which are undesirable.
  • the ideal hardness of the alloy would be in the range of a No. 2 to No. 3 hardness on the MOHs scale. An example would be soft aluminum whereby a sharp knife blade can easily draw shavings therefrom. When the hardness reaches the above-mentioned degree, the shavings become very difficult to cut and will usually ignite as they are cut. If the misch metal percentage of the alloy is less than 50%, it is difiicult to strike a spark. A desirable balance of percentages provides a stick 10 that can be easily shaved without preigniting the shavings 12 having adequate sparking ability and sulficient magnesium for an adequate amount of heat energy.
  • the operation or method of use of the present invention entails holding the metallic stick 10 in one hand and a pocket knife 14 in the other. With a scraping action of the blade 16, as seen in FIGURE 1, shavings 12 are collected on the substance 18 which is to be ignited.
  • the substance 18 could be wet or dry wood in any form.
  • the substance 18 could actually be any material capable of combustion with a lower kindling temperature than 2800 C.
  • the shape of the stick 10 can be rectangular, as shown in FIGURE 1, or other cross sectional shapes such as 10a and 10b illustrated in FIGURES 3 and 4. Actually, the alloy does not have to be formed in a stick shape as shown in the drawings, but can be of any configuration.
  • FIGURES 1 and 2 the stick 10 is shown with a hole 20 in the end thereof to facilitate an ordinary key chain 22.
  • FIGURE 5 illustrates a modified form of the stick 10c whereby a handle 24 is attached to the end thereof for easier handling.
