J. GIOIOSA TORPEDO.

JOSEPH GIOIOSA, -F EST MILTON, MASSACHUSETTS.

TORPEDO.

T0 all.wwm it may concerne:

Be it known that I, JOSEPH GIOIOSA, a citizen et the United States, residing at East Milton, in the county of Norfolk and State of Massachusetts, have invented new and useful Improvements in Torpdoes, of Which the folloWing is a specification.

This invention relates to improvements in torpedoes.

The object of the invention is to provide a torpedoofthe type used for fireworks and amusement purposes, said torpdo being so constructed that it Wlll not be easily exploded prematurely during handling .or transportation.

Another object of the invention is to increase the strength of the covering of a torpedo over that of articles of this character as previously manufactured and thereby produce an article which in the event of not ha.ving been projected against an obstacle with sufiicient force to detonate the explosive charge will not break open, thereby scattering said charge and rendering the article inoperative, but which Will be sufficiently strong to withstand repeated contact With said obstacle until finally detonated.

Another object of the invention is to render the article reasonably impervious to a moist atmosphere.

Still another object of the invention is to produce a torpedo of the character described having a novel and distinctive contour.

The invention consiste in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.

Referring to the drawings:

Figure 1 represents an elevation of a torpedo embodying my invention.

Fig. 2 is a vertical, longitudinal section taken on the line 22, Fig. 1.

Fig. 3 is an elevation illustrating one of the stages of construction of the torpedo.

Fig. 4 is an elevation illustrating another stage of construction of the torpedo.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 5 represents a body of material constituting the combination of an explosive charge 6 and a means 7 for detonating said charge intermingled together. The explosive charge 6 is composed of chlorate of potash, antimony and sulphur, each in powdered form and mixed together in Specification of Letters Patent. Pfltented Feb, 14, 1922 Application filed Mareh 18, 1921. Serial No. 453,412.

suitable proportions. The means 7 for detonating the charge 6 consists of a quantity of small stones,' coarse gravel or the like with which a suitable quantity. of the explosive charge 6 is mixed as well known to those skilled in the art.

Enclosing the material 5 is a ,covering consisting of a layer of plain paper 8 et sufiicient area to surround said material and allow the edge thereof to be twisted to form an approximately oonical shaped portion 9 as. illustrated in Figs. 2 and-3. A second layer of paper 10 of slightly larger area than that of the layer 8 and covered .upon both.sides thereof with a suitable moist adhesive material, as, for example, paste or glue, is placed around the first layer of paper 8 and the edge thereof twisted around the coni-cal portion 9 at 11 as illustrated in Fig s. 2 and 4, thereby increasing the size of the conical extension. The layer of paper 10 and the adhesive material thereon is then allowed to dry at which time it Will adhere to the layer 8 and the adhesive material Will act t0 stick the folds of the paper together, thereby causing the conical portion 11 to hold its shape.

The article as illustrated in Fig. 4 is then dipped in another suitable adhesive material as, for example, paste or glue, and immediately placed in a receptacle containing fine sawdust or the like, in which it is rolled until tho-roughly covered with said sawdust whieh soon becoming saturated with the adhesive material, forms a plastic covering 12 therearound as illustrated in Figs. 1 and 2. This covering is then allowed to dry, thereby forming a comparatively hard outer surface for the article.

If it is desired to have the finished product colored, the article may be dipped in suitable coloring matter and allowed to dry, or the sawdust may be colored prior to being applied as previously described.

A torpedo constructed as described is casily and quickly assembled and produces a finished product having a novel and distinctive contour for articles of this character. The outer covering increases somewhat the weight of the article, thereby allowing it to be pnojected; against an obstacle with a greater impact than would be the case if it were eliminated. The outer covering also acts t0 strengthen the casing enclosing the inner body of material Which includes the explosive charge and the means for detonating said charge and produoos a torpedo whch is safor to handle andloss likely to be dotonatod profiitutly.

I claim:

1. A torpodo omboding thoroin an oxplosvo charge, means intorm1glod thoro- With adaptod t0 dotonto said charge, a layer of shoot matorial onclosing sad oxplosive oharge and said dotonating means, the edge portion of Said sheot matorialboing twistod into a -concal shapod projection at one side of said explosive charge and dotonating means, a second layer of shoot matorial covorod with an adhesivo substance upon both sidos thereof and appliod to 'sad first montionod layer Of shoot matorial, the edge portion of sad Second layer of shoot matorial boing twstod around sad* conical shapod projection and inoasing tho Size theroof and an outor -oovoring adhoring co said outer layer of shoot material and composod of sawdust saturated With an adhosivo matorial. r

2. A torpo;do embodyng thoroin an oxplosive charge, means intormingled thorewth adaptod t0 dotonato said charge, a layer of shoot matorial onolos1ing sad oxjol'osvo chargo'and said detonating moans,

' tho edgo portion of said shoot matorial being twistod into a conical shapod projection at onosido 0f sad explosive charge and dote nating moans, a second layer of shoot mato1al covored with an adhosvo substance upon both sidos thereof and applied 130 said first montionod layer of shoot marial, tho odge portion of sadsocond layer of shoot niato1ial boing twisted around sad conical shaped projection and incroasing tho sizo thoreof, a coating of adhosivo matorial covering sad outr layer of shoot materal and a layer of sawdnst adhoring to said adhesivo matorial andcombiningtherowith to form a hard outor covoring for said torpedo;

In tostim0ny whoroof I have horounto sot my hand in presonco of two subscrbing Wtmesses. w
