SPECIFICATION forming part of Letters Patent No. 236,889, dated January 25, 1881.
Application filed October 30, 1880. (No model.)
jects of Germany, have invented a new and useful Improvement in Fire-Kindlers, which improvement is fully set forth in the following specification and accompanying drawings, in Which- Figure l is a top or plan view of a sheet of lire-kindlers embodying our invention. Fig. 2 is a transverse section thereof, also showing the mode of packing the kindlers. Fig. 3 is a perspective view ot' one ofthe kindlers.
Similar letters of reference indicate corresponding parts in the several figures.
Our invention consists of a composition of matter forming an improvement in fire-kind- 1ers.
It also consists in forming the kindlers of hollow pyramidal form, whereby they Amay readily pack one with another and possess a large burning-surface.
It further consists ot' a novel striking-surface. for the tips of the kindler, by which said kindler may be readily ignited, and matches are dispensed with, the tips being of such composition that they cannot be ignited without the employment of the prepared striking-snrface.
Referring to the drawings, A represents the kindlers, which are molded of a composition of inflammable material in the form of hollow pyramids, a number of which are produced in a sheet united at their base rims, thus admitting each kindler' to be easily broken olf as required. The sheets maybe placed one above the other, it being noticed that the apices of one sheet project into the hollow of the contiguous sheet, so that the several sheets interlock and t each other snugly, thus providing convenient means of packing and tra nsporting the kindlers.
The composition employed for the kindlers is as follows: thirty parts granulated cork, sixty parts rosin, ve parts oily matter, ve
parts petroleum residuum. The rosin is melted 1 over a slow fire, the oily matter added, and cork gradually stirred in with them, after which the warm mass is poured into molds, the composition readily admitting of molding, and producing a kindler which is highly iniammable, burns long without unpleasant odors, and is inexpensive.
Each kindler has its apex or point tipped or dipped, as at a, with the following composition: four parts chlorate of potassium, two parts chromate of potassium, two parts verlnilion or red lead, one part sulphur, one part chalk, one part sandstone, and one part gumarabic. This provides a convenient form of igniting the kindlers by friction or striking, and dispenses-with matches for such purpose; but the composition is of such nature that it cannot be ignited unless when struck on a prepared surface, the latter being formed of the following materials: one part amorphous phosphorus, one part grains of sulphur, and one part sulphate of antimony. This insures the safety of the kindlers, as the tips do not ignite by friction with other surfaces than one specially prepared.
Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, :is-
1. The tire-kindler composed of cork, resin, oily matter, and petroleum residuum, substantially as and for the purpose set forth.
2. A fire-kindler of hollow pyramidal form, provided with tip a, ot' highly-infiammable material.
3. A sheet of hollow pyramidal lire-kindlers, connected as shown, each being provided with an inflammable tip, a, substantially' as and for the purpose set forth.
4. A nre-kindler of hollow pyramidal form, substantially as and for the purpose set forth.
