.ALFRED T. VOELKER, F GLASSBORO, NEW JERSEY.

TORPEDO.

Application led July 15, 1921.

To all whom it may concern:

Be it known that I, ALFRED T. VOELKER, a citizen of the United States, residing at Glassboro, in the county of Gloucester and State of New Jersey, have invented certain new and useful Improvements in Torpedoes, of which the following is a specification.

One object of my invention is to make a toy torpedo of a novel construction which can be easily and cheaply manufactured and at the same time can be easily handled and packed without breaking.

Another object is' to. so produce my improved torpedo that while it can be cheaply and easily manufactured, the parts will hold together until it is red by throwing the same.

These objects, and other advantageous ends which will be described hereinafter, I attain in the 'following manner, reference being had to the accompanying drawings in which- Figure l is a perspective view of a torpedo made in accordance with my invention,

Figure 2 is a perspective view showing a sheet of material, such as paper, which is rolled and illustrating one step in the formation of one ofthe sections of the shell of my improved torpedo,

Figure 3 is a perspective view showing the rolled sheet yhaving been partially folded over one end of the rolled structure and illustrating another step in the production of my improved tor edo,

Figure 4f shows said section completed,

Figure 5 is a detached perspective view of the sections of the shell 1n a position illustrating that one of the sections can be televscopically slid in the other section with the closed ends opposed to each other and including therebetween a filling of explosive material,

Figures 6 and 7 represent enlarged sectional views of the shell sections detached, and

Figure 8 is a sectional view of the completed torpedo.

Referring to the drawing, my improved torpedo includes a shell 9 made up of two cup-shape sections 10 and 11. These cupshape sections 10 and 11 are similarly constructed with the exception that the section 10 is of slightly smaller external diameter than the -section 11 so that the sections,

which are preferably of cylindrical form,

Serial No. 484,908.

can be slid one into the other by exerting a slight pressure; the friction between the sections being suflicie-nt to hold them in their telescoped position. .as shown in Figure S, and to include therebetween a filling 12 of explosive material. Preferably a coating of adhesive material is placed on either or both of the sections so that when they are forced together they will be secured one to the other. If desired the external diameter of the section 10 can be made slightly greater than the internal diameter of the section 11 so that it will be necessary during the telescoping m'ovement of the sections to slightly expand the diameter of the section 11. This latter also tends to securely hold the sections together.

I make the sections 10 and 11 in a novel manner hereinafter described and since both of the sections are similar with the exception of their diameters I will describe the manner of producing one of the sections and it will be understood that the other section is similarly) made.

' Referring first to Figure 2, I use a sheet 13 of non-metallic lib-rolls material such as paper; said sheet being made in strip form and this sheet is first rolled as shown at 14. This rolling, if desired, may be done upon a mandrel (not illustrated). I then fold the end portion 15 of the lrolled sheet by first pressing said portion 15 as shown in Figure 3; the initial folding preferably taking place at the portion which includes the outer edge 16 of the sheet. A series of these folds are made as shown at 17 in Figure 4 so as to provide a closed end 18. The portion of the sheet which is to be folded is preferably coated with adhesive material so that when folded the fiaps of the folds will remain in their folded positions. Also by using a thin exible tough paper the fold when thus made will retain its position; the intersection of the flaps with the cylindrical surface 19 preferably being made sharp or abrupt. This completes the making of the cup section and by telescoping two of these sections together with `their closed ends 18 opposed to each other, as shown in Figure 8, and having the filling of explosive material therebetween, the 'torpedo will be completed. I preferably make the sections 10 and 11 of such length that when they are put together the closed end of the section 10 will be ush with the edge of the open end of the section l1.

It will be noted that by thus making the cup sections that each section will have an integral closed end or in other words an end which is formed of the same material out of which the sides of the section are produced.

Thile I have described my invention as taking a particular form, it will be understood that the various parts of my invention may be changed Without departing from the spirit thereof, and hence I do not limit myself to the precise construction set forth, but consider that I am at liberty to make such changes and alterations as fairly come Within the scope of the appended claim.

Having thus described my invention, what naine to this specification in the presence of two subscribing Witnesses.

ALFRED T. VOELKER.
