.i To' all what?l 'it may concern:

Beit known that I, Josnr' B. DECKER, a citizen of the United States, residing at Elkton, in the county of Cecil and State of Maryland, have inventedv certain new and useful Improvements in Processes of Making To Torpedoes and the like, of which the following is a specification.

This invention relates to explosives, and inore particularly to methods of making toy torpedoes, toy grenades, and the like.

An object of the invention is,the provision of a method of manufacturing toy torpedoes in which the possibility of explosionsiis reduced to a minimum.-

In the .manufacture of toy torpedoes, mixtures of chemicals are employed consisting of materials which are susce tible to easy oxidation, materials capable o supplying oxygen, and an abrasive. In the manufacture of such explosives,'these materials are first mixed in a large batch and the amount of the mixture necessary for eachl torpedo is separated therefrom. Such mixtures, due to shock, concussion, or friction, frequently explode accidentally and the material capable of oxidation is rapidly oxidized by the oxygen carrier. This prevents a serious danger factor due lto the mixing of the explosive materials prior to the introduction of the same into the toy grenade .or torpedo shell. A toy torpedo or grenade 'is in itself, relatively .safe to handle as the amount A of explosive encased in the shell or the individual charge is too small t0 cause an explosion. p

In practicing the present process, I minimize the danger of explosions by placing the material capable of oxidation and the abrasive in the tor edo shell or chamber and then add the oxidizingmaterial to the mix- Vture. In the use of a mixture consisting of sulfur, potassium chlorate,'and antimony sulfide in which the latter material, together with a certain amount of avel, acts as the abrasive, I first mix t e sulfur and antimony sulfide. Sulfur is capable of easy oxidation but in the absence of a ready sup,

ply of ox en, is not explosive and a mlxture of sul7 ur and antimony sulfide is therefore not explosive. These materials may be mixed in relatively large quantities in the proper proportions, such as are generally employed in the manufacture of torpedoes and may be readily handled without danger. The mixture may be placed in shells or castoy torpedoes or toy grenades and the proper proportion of potassium chlorate or other materla serving as an oxygen carrier is4 ings `of the' size generally employed in.`

then added to the individual charge within the shell. or casing. A small amount of gravel is added to facilitate the action'ofl the antimony sulfideor other abrasive and the receptacle is then capped and carried toa coating machine where an outer casoperation, the contents 'of the receptacle are thoroughly mixed and the ,article is then,

in condition to'function properly. If the mixlng, or other handling of .the ingredients Y ing is placed thereon. During the coating explosive materi cldent.

In the accompanying drawings',n'-I have:

al to cause a dangerous 'acshown one embodiment of the invention. i In this showing l Figure l is an `elevation of the finished torpedo,

Figure Qlis a central vertical sectionalf view, and,

Figure 3 is a perspective view of the innery casing. orshell.

Re errrng to. the drawings, the reference numeral l designates an inner shell of a proper size to receive theexplosivemixturer of the torpedo. This shell is provided with a filling 2, formed of a mixture of sulfur o r Iother readily oxidizable material, potassium chlorate, or other carrier of. oxygen,

and antimony/'sulfide or other abrasive material.y Gravel 3 is arranged within the mixture, as shown. The casing is provided with a suitable cap 4 which is adapted to be placed thereon after the charge has been arranged within the shell and an outer casing 5 is arranged over the shell and formed in anysuitable shape. In the drawings, I have shown a torpedo in the form of a` sphere in which the outer casing is formed of small disks 6 of paper which overlap each other andare secured in position by means of a suitable adhesive.

In practing the process, the material to be oxidized` and the abrasive are first mixed in the proper proportions and an individual charge of this mixture is placed in each ofthe shells 1. The oxygen carrier and gravel are then placed inthe top of the shell and the shell capped. The outer casing 5 is applied bymeans of a suitable coating machine and the agitation of the device during the coating operation properly mixes` the various ingredients to form an explosive mixture that will properly function.

As stated, an explosion of an individual shell is 'not serious and will notgenerally result in 'a hazardous explosion or lire.

Itl is to be understod that the form of my invention herewith shown and described is tobe taken as a preferred example of the-same, and that various changes in the shape, size, and arrangement of parts may be resorted vto without departing from the spirit of the invention or the scope of the subjoined claims.. f

I claim: Y

l. The process of making toy torpedoes which comprises placing a mixture of a readil oxidizing material and an abrasive in a sliell, adding an oxygen carrying material thereto, and placing a coating over the shell.

2. The process of making toy Atorpedoes which comprises placing a mixture of a readily oxidizing material and an abrasive in a shell, adding an oxygen carrying material and gravel thereto, and Vplacing a coating over the shell.

3. The herein describedprocess of manufacturing toy explosives which comprises forming a mixture of a'readily oxidizing material and an abrasive, placing` an individualchargevof said `mixture' in a shell, adding an oxygen carrying material thereto, and closing said shell. y

4.. The herein described process of manufaeturing -toy explosives which comprises forming a mixture .of a'readily oxidizing Amaterial and anabrasive, placing an individual charge of saidmixture in a shell,

material there-` agit-ating it to `adding an oxygen carxging1 iateiial e s e ,an agi gravel thereto, ea ping t ing it to mix sai materials.

6. The herein described process of manuv faeturing toy explosives which comprises forming a mixture of readily oxidizing material and an abrasive, placing an individual charge of said mixture in a shell, adding an oxygen carrying material thereto, capping the shell, and applying an outer coating thereto, said shell being agitated durin` the application of thecoating whereby sai `iiigredients are 4thoroughly mixed. Y

7. The method of making toy torpedoes which com rises placing a. mixture of a readily oxi4 izin'g material andan abrasive in a shell, and adding the desired quant-ity of an oxygen carrying material thereto.

In testimony' whereof, I aiix my signature in presence of 'two Witnesses.
