,4 TTORNE Ys' Patented Sept. 26, 1939 UNITED STATES PATENT o-F'F ciz My invention relates to fireworks.

-In particular, this invention has to do with a fireworks article which, when ignited, projects a jet of flame. g

It is an object of my invention to provide a molded. formed pyrotechnical means. for forming. when ignited, a -iet of fiame or smoke. This member is damp as a result of the process of its manufacture and its composition, and it is the l object of this invention to provide a method of dehydrating this pyrotechnical member so that it will readily ignite because it is dried quickly.

- It is a further object to provide such a dehydrated .pyrotechnical member with a casing capable of withstanding combustions of the pyrotechnical composition without rupturing so that the smoke and fiame may pass out through a vent in the casing through which a fuse has been introduced. This casing is preferably made of a go conglomerate as hereinafter described.

It is an object to provide a fireworks article such as a rocket having a dehydrated smoke and; fiame producing composition, the gases from which are ejected through a conglomerate, relagg tively hard and strong casing to which casing there is attached, preferably by the adhesiveness of the casing,askyrocket stick.

Referring to the drawings:

4 Claims.- (Cl. 102-23) Figure 14 is'a side elevation thereof.

Figure 15 is an elevation of a cylindrical body embodying the features of this invention} Figure 16 is a vertical section therethrough.

It will be understood that the smoke and flame 5 producing and gas generating molded interior member may be either cylindrical or off any other form,.such as in the form of a ball, etc. i 1

According to my method, I first mold a 0011-. glomerate mlxtureof charcoal, salt'peter, sulphur, 10 aluminum magnesia powder or powders and any other color producing materials that may be necessary.

This molded body is then subjected to the second step of my process for the purpose of dehydrating it. Great dimculty has been experienced with rockets over long periods of time that remain damp by reason of the fact that the interior composition has 'been enclosed immediately after making with the casing hereinafter described. no Rockets so made would not ignite. Therefore, after the pellets l are molded and are ready to be tumbled to apply the conglomerate coating, before this coating is applied, I apply a mixture of silicate of soda, whiting and charcoal which is poured over the pellets. Any-desired method of coating them may be employed,-such as tumbling, dipping, spraying or brushing. This coating is designated in the drawings as 2. It has the effect of making the pelletsdry very quickly and of. dehydrating them. It also protects the pellets against the absorption of moisture as a result of the application of the next succeeding coating which forms a hard casing to complete the pyrotechnical device. The proportions of silicate of 5 soda,- whiting and charcoal are as follows:

i v Per cent by we ht Silicate of soda 80 y Y Whiting 13,, 40 Charcoal 6;;

The next step of the processistoapply the conglomerate coating 3' which may be made from a mixture of. glue, wood fiour, granular material, sawdust, confetti or aluminum flakes or fiitter. The pellets I with their coating 2 are placed" in a tumbler which is agitated or rotated. The sawdust or granular material is sprinkled over the pellets having the glue applied thereto so that the casing or coating 3 is gradually built up.

At this time or subsequently, the sky rocket sticks! may be applied in any desired manner.

The resultant iireworks article is ignited by means of a fuse 5 whichis inserted throu h the portSofth casirigorcoatingLasimilarportI in the coating 2, and into areceiving opening 1 in the pellet i.

This molded pellet I, whenignited. pr duces sparks and flames and generates gases, the exit of which, through the opening through which the fuse 5 as been inserted.- either tends to bring thearticle upright or to cause its flight as in the case or a sky rocket.

It will be understood that tion of the pyrotechnic pellet I may be varied both as to the materials and colors produced-and may be utilized either to produce smoke alone or in combination with sparks or colors. I .ikewi se, the conglomerated and agglomerated casing or covering 3 may be otany desired material.

Figures 11 to 14 inclusive illustrate a spinner embodying the features of this invention. When a fuse is ignited, it causes the spinner to rotate and the wings 9 on the spinner will.cause the entire body to elevate.

Figures 15 and 16 show a cylindrical body embodying this invention in the nature of a fountain which is adapted to hold its upright position when the fuse is ignited and the contents blow out or the fuse hole.
