HANS GRllNEWALD, OF HANQVER, GERMANY.
MANUFACTURE OF FIREVIORK ARTICLES.
N Drawing; Application filed. April 5,
To all 107mm it may concern:
Be it known that I, HANS Gnif'zznwano, citizen of Germany, and a resident of Glockseestrasse, in the city of Hanover, Germany. have invented certain new and useful Improvements in the Manufacture of F rework Articles, of which the following is a specification.
This invention relates to pyrotechnics or fire-work articles ant, among other important objects it is intended to generally improve and facilitate the course of manufacture of such articles, and to greatly increase the number and variety of mixtures and of the pyrotechnic, optical, csthetic and other effects produced. The invention devises means of obtaining entirely novel fire-work articles, such as Bengalic flames, lights, roc rets, parlor fountains, sparklers, stars and broadly speaking, of all articles of the kind producing a pyrotechnic light or firework phenomenon. In accordance with the previous art firework articles, such as for instance Bengalic sticks or the like, were gen erally manufactured by dipping the wires or sticks or the like into the pasty or liquid composition, or the composition was introduced into shells or tubes, and by this means fire work articles of difierent description were produced by a judicious selection of the various compositions. With this method of working, however, the stuffing of the tubes or shells, the dipping or the sticks, wires, cords or the like necessitated a great amount of help and much time, and there was the further drawback that it was impossible to app ying a plurality of compositions by dipping upon one and the same carrier, the stick, wire or the like, or to immerse any desired length of sticks or the like; nor could the tubes or shells be made of any suitable length desired.
These inconveniences are overcome according to my invention by means of which the operator is enabled to apply a plurality of compositions ,lCCSSSlVQl) onto the sticks, wires cords or the like, and for any length desire By this means one is enabled to produce the most variegated pyrotechnic eftects combined with the maximum of burn in period which may be extended to any desired degree. in view of these and other l1 ects I preferably proceed by shaping and U dr composition of "illfl pieces of fire work any suitable size, providmg them Wltll. perforations, and then slipping such pieces to 1924. Serial No. 704,512.
which any desired shape may be given, onto a wire, stick. piece of asbestos, an igniting cord or the like, such pieces of composition are pretera-ihly rnumtacturcd by machinery. and in this manner chains, rings, stars and any other table figures or configurations may be ohtamethwith the sticks, wires and cords or the like as carriers, and by the aggregation and combination oi various dit 'l'erent compositions the most wonderful, astonishing pyrotechnic eli'ects of constantly changing kind and of practically unlimited turning period may be obtained. Thus for instance, it does not present any diiiiculties to mount a plurality oi compositions upon the sic-called Ben alic sticks, heretofore merely employed tor the production or" a light phenomenon. halo or the like, and to make such wood sticks or wires of any length desired. There is also the possibility of introducing other articles, such as Christ mas articles, tree decoration, tinsel and the like between the individual pieces of composition, and to connect the pieces of composition by a special igniting cord, which is preferably wound around the carrying wire or the like. As a point of importance it should also be pointed out that, when the several pieces of composition may be bought, every customer is enabled to make his own ,:ombinations 0t pyrotechnic effects in the most simple manner and according to indi visual taste. A great saving of costs is also realized by my invention, as there is no further necessity of dipping the sticks or Wires or of filling and stufiing the shells, casings or the like. The pieces of composition are produced and shaped automatically and may be automatically mounted upon the cord, the wood stick or wire. Then, the ingredients of the composition, and the aggregation of different kinds of compositions may be selected in such a manner as to dispense in many cases with the use of the highly dangerous potassium chlorate, inasmuch as this substance is not indispensable in the manufacture of the composition by machinery from dry ingredients, while with the pasty or liquid compositions the presence of potassium chlorate was necessary. Instead of but one a plurality of carriers may also be used. The invention is not restricted to the specific form of embodiment herein described, but is susceptible of being applied in various ways, and to be modified in ac cordance with particular requirements and without deviating from the spirit of the invention, as pointed out in the claims hereunto appended.
I claim 1. The method of producing fire Work articles, Which consists in spacedly disposing pieces of pyrotechnic material, and disposing said pieces upon an elongated carrier.
3. The method of producing fire Work articles, which consists in shaping a plurality of dry perforated pieces from pyrotechnic composition, spacedly and displaceahly assembling said pieces upon an elongated carrier, disposing non-pyrotechnic articlesupon said carrier between the pyrotechnic pieces and conductingly connecting the latter.
4. The method of producing lire Work articles, which consists in shaping a plurality of separate pieces of fire work composition, and heat-conductingly aggregating and mounting such pieces in, a substantially dry condition upon a substantially cord-like carrier.
5. The method of-producing fire Work articles, which consists in shaping a. plurality of separate pieces of fire work compositions, mounting these pieces and other articles upon a substantially thin, elongated carrier, ancl'connecting the pieces of lire Work composition with each other by igniting means separate from the other articles.
6. As an new article of manufacture,.a pyrotechnic article, comprising a. plurality of perforated .drypieces of pyrotechnic composition, spacedly and displaceablydisposed upon. an elongated carrier.
T. As a new article of manufacture, a pyrotechnic article, comprising a. plurality of perforated dry pieces of pyrotechnic cmnposition, and of Christmas articles, spacedly and displaceahly disposed upon. an elongatedcarrier, and ignitingmeans. connecting the pieces of pyrotechnic composition, and mountedupon the carrier.
8. As a new article of manufacture, a pyrotechnic article, comprising a. plurality ot'dry, hardened pieces of pyrotechnic composition, a non-exploding, non-conducting carrier, supporting said pieces in spaced relation to. each other, additional unexploding articles disposed on said carrier, and. igniting means mounted on the carrier and connecting the pieces of pyrotechnic material.
