Claims.

This invention relates to improvements in track torpedoes and methods of making the same, the principal object being to provide a novelly constructed torpedo and a simple and eflicient method of making the same in large quantities at low production cost.

tainers as described briefly above, the inner or receptacle sections of such containers being of such dimension that they will hold. the exact quantity of detonating material required for a charge when filled. The method further com prises the placing of a plurality of the said inner sections in vertically disposed position and in juxtaposed relation to each other, preferably in a shallow box-like tray,,so as to completely fill the same and maintain the juxtaposed sections in the desired upright position. The detonating material, which takes the form of a powder, is then introduced into the upright receptacle sections simultaneously until theyare filled, the filling operation being carried out by any suitable means which will spray or similarly introduce the detonating material into all of the receptacle sections at the same time. The filled sections are then removed from the shallow tray and the outer or cover sections of the containers are telescopically applied to close and seal thecontainer of each torpedo. g,

The novel features of construction of the improved torpedo, as well as the method of making it, are more clearly set forth hereinafter in the detailed description of the invention,v as illustrated on the accompanying drawing. In the drawing:

Fig. 1 is an exploded perspective view of the telescopic container of one form of the torpedo; Fig. 2 is a perspective view of the containerin closed condition;

Fig. 3 is a perspective view of the container disposed in proper relation to its flexible attaching strip and the strap for attaching these elements together;

Fig. 4 is a perspective view of the completed torpedo; 1

Fig. 5 is an exploded perspective view of a modified form of torpedo; and

Figs. 6 and 7 present a plan and an elevational View, respectively, of the shallow tray hereinbefore mentioned, which is preferably used to carry out the proposed method, the views illustrating clearly the manner of positioning the receptacle sections of, the containers in the tray.

Referring to Figs. 1 to 4 of the drawing, there is disclosed therein one embodiment of the track torpedo of the invention. As shown clearly in Fig. 1, the container, which forms the body of the torpedo, takes the form of a telescopic container comprising an inner or receptacle section 1 and an outer or cover section 2. Each of these sections is formed with a closed and an open end. They may be formed of any suitable material such as those in common use in the making of such torpedoes, a heavy or tough paper preferably being used for this purpose. In accordance with the invention, section 1 is of such dimension that it will hold the exact quantity of detonating material to constitute a charge. In the illustration of Fig. 1, a portion of the section is broken away to illustrate the detonating material 3 therein. The section may take any desired shape,

the shape illustrated merely being a preferred form. The outer or cover section 2 is, of course, shaped similar-to the inner section and of such dimensions as to snugly cover and conform with formed of paper, is wrapped about the strip and container. The attaching strap is preferably formed so as to conform in width with the length of the assembled container. In applying the attaching strap to the elements, the container may be placed upside down centrally upon the strap,

the strip 4 placed centrally on top of the coni tainer, as illustrated in Fig. 3, and the ends of the strap wrapped about the assembled elements and attached by any suitable means, such as an adhesive. The completed torpedo with the attaching strap in operative position is illustrated in Fig. 4.

In Fig. 5, there is illustrated a modified form of torpedo, wherein container sections la and 2a are attached to individual attaching strips 4a and 4b by crimping the outer ends of the sections about the strips as illustrated at 6. In this form of torpedo, the sections are formed similar throughout their length with both ends open. They are preferably formed of paper as before and may take any desired shape. The outer ends of the sections are placed about the ends of strips 4a and 4b and then folded or crimped as illustrated. A suitable adhesive or any other means may be used to attach the crimped ends of the sections to the strips, such adhesive being applied to the inner surface of the crimped section ends or to the strips themselves. In this instance also, the inner or receptacle section la is of such dimensions when attached to its associated strip that it will hold the exact quantity of detonating material required for a charge.

Figs. 6 and '7 illustrate the manner in which it is contemplated to fill a plurality of containers as a step in the method of manufacture of the complete torpedo. The method in question is illustrated in these figures as applied to a container of the form of torpedo illustrated in Figs. 1 to 4, but it is to be understood that the method is equally applicable to the modified form of Fig. 5. In accordance with the method as applied to the torpedo of Figs. 1 to 4, after the sections of a plurality of containers have been formed, the inner or receptacle containers 1 are placed in closely adjacent position in a suitable shallow boxlike tray '7. Six of the container sections are illustrated at 8 in vertical position with their open ends exposed. The remaining sections completely filling the trap are illustrated diagrammatically by means of cross lines but it will be understood that it is intended that the tray be completely filled with the closely positioned sections. As shown in Fig. 7, the height of the tray is of such dimension that the upper ends of the vertically disposed sections protrude above the tray so that they may be readily withdrawn therefrom after filling.

After the tray has been completely filled with the container sections, as set forth above, they are filled simultaneously with the proper quantity of detonating material. This filling operation may be carried out by hand or by any suitable apparatus for automatically filling the sections. In

the case of manual operation, the operator may use a scoop or trowel to spray the powdered detonating material over the open end sections. After partially filling the sections simultaneously in this manner, he may pack the detonating material by jarring the tray. The filling operation may comprise successive filling and jarring until all the sections are completely filled, at which time, the exact charge will be held by each of the sections.

After filling, the sections may be removed and the various torpedoes completely formed in the manner set forth above. It is important to note that the detonating material when packed during the filling operation, as explained above, will not fall from the filled sections even if some of such sections should topple over in the tray during the removal thereof. Due to the successive jarrings of the tray as above set forth, the powdered detonating material becomes firmly packed, the particles adhering together. Thus the exact charge is retained by the sections at all times.

Obviously, tray '7 may be large enough to accommodate any desired number of container sections, the number of such sections which may be filled simultaneously being unlimited theoretically and limited only by practical considerations. If the tray is made small for hand operation, it may be provided with suitable handles (not shown) to facilitate handling by the operator especially in the jarring process. If the tray is extremely large, any suitable means for effecting the jarring thereof to pack the detonating material may be provided. As indicated above, the filling may be carried out by any suitable apparatus which functions to spray the material over the container sections after the manner of spraying by hand. Since the container sections are closely positioned, practically no detonating material is wasted and the small amount which might enter the crevices between. the containers may be readily salvaged from the bottom of the tray after the removal of the filled sections.

In the manufacture of torpedoes of the form shown in Fig. 5,, the receptacle sections of the containers may be placed upright in the tray after being completely formed with their associated strips attached.

It will be apparent that the method proposed herein is simple and eflicient in the filling of torpedo containers which constitutes the most important and difficult step of the process of H manufacturing torpedoes. Obviously, by means 100 of the method of the invention, a large number of torpedoes may be simultaneously constructed at low cost. A large saving in time and labor on the part of the operator is effected by this method.

Although specifically illustrated and described 105 herein, the invention both as to the construction of the torpedo and the novel method of making the same is not to be limited by the disclosure but is to be understood as of such scope as to inelude any variations or modifications as would no occur to persons skilled in the art and within th scope of the appended claims.
