To all whom it may concern:

Be it known that I, FRANK BUTCHER, a citizen of the United States, residing at Versailles, in the county of Alleghenyand State of Pennsylvania, haveinvented certain new and useful-Improvements in FiberlaseRailway-Torpedoes, of whichlthe following is a specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in fiber case railway torpedoes, made of a sheet of fiber so folded and cemented together that a strong, durable and waterproof torpedois produced.

The object of my invention is: to form the casing of a fiber torpedo from a blank of fiber and so fold it around the explosive tablet or compound that the same is wholly inclosed and at the same time provide means whereby the lead or spring attaching strap is securely fastened thereto.

A still further object of myinvention'is to provide a torpedo ofthis character in which a flat lower face is formed'to rest upon the rail and at the same time provide a cheap, simple and more effective torpedo having certain details of structure hereinafter more fully set forth.

Referring now to the drawings: Figure 1 is a perspective view of my improved torpedo applied to the rail and using the lead attaching strap. Fig. 2 is a perspective bottom plan view of the torpedo shown in Fig. 1. Fig. 3 is a vertical transverse sectional view taken on the line 33 of Fig. 1. Fig. 4 is a longitudinal sectional view taken on the line 44 of Fig. 3. Fig. 5 is a perspective view of the blank from which my improved torpedo is formed, showing it in a partly folded position. Fig. 6 is a bottom perspective view of a modified form of torpedo embodying my invention, showing a spring clip applied'thereto. Fig. 7 is a longitudinal sectional view of Fig. 6. Fig. 8 is a top plan view of the blank ofwhich my torpedo is formed, showing the means'by which the spring clip attaching plate is secured to the blank.

Referring now to the drawing, 1 represents the blank of which my improved torpedo is formed, and consists of a main bodyportion 2, having at one side the flap 3, having its ends beveled, as indicated at 4. The outer edge of the flap 3 is provided with a flap 5, which is of an area approximately equal ato:-that:of;.the explosive -compound:6,ato be inclosed in the..torpedo. Theouter edgeof :the 'fiap 5 is provided witha flap 7 which has its edges -8 diverging outwardly and formed on: the outer end ofthesaid flap 7 is qca flap: 9. -Thisflap 9.isof,an area equal to that of'the main-body portion 2 .and fits tightly-down upon the same, as will be hereinafter morefully described.

The main body I portion; 2 of the torpedo,

-in.1the form shownin'Figs. 11-.to 5,.is provided with two longitudinally extending .spaced slits -10 and 11,,through which the lead attaching strap 12 is Et-hreaded. The blank of which the torpedo is. formed; is preferably of fiber, such as paper and it. has been found that they ordinary paper roofing, such as is commonly used forms, a yerygood .com-

position out of which tOr2St2l1I1P the blanks.

. Such roofingis: usually flexible and enables the blankto be readilyifolded. The ends of the body-portion :2 are provided with-flaps .13 and 14:, .wh-ichaare oft-a.1ength,.slightly greater than the inclined walls 1410f the flap 3, the purpose. of which; is to allow the. flaps l3 and 14. to assume a. curved .position and be folded inwardly as clearly .shown; in Fig. 4. In .assemblingrthe torpedo theoexplosive compound ortablet 6 is placed upon the upper faceofthefiap 9 andfolded over upon the flap 5. The upper face of the body-portion is then coatedwith cement or other waterproofing material and the lower face of the flap 9 is folded down uponthe I body-portion and cemented thereto, thefiaps 3 and "'7 covering the sides of the explosive tablet 6. The ends of the torpedocase are then given a heavy coating of cement as indicated at 15, and the end'fiaps folded in- 'wardly and upwardlyundenthe lowerface of the fiap .5, as clearly :shown inFig. a of the drawings.

In the modification shownin Figs. 6, 7 and 8, instead of providing the main-body portion'2withthe parallel longitudinal slits 16 by a rivet 20, as shown in Figs. 6 and 7.

In the form shown in Figs. 6, 7, and 8, the blank is made precisely as that shown in the first five figures and needs no further description.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. A railway torpedo composed of a blank having a body portion, flaps carried by one side of the body portion and constructed and folded to form an open-ended case having a reduced upper face, an explosive com pound within the case and said body portion having flaps at the ends of a length greater than the open ends of the case and adapted to be folded into the same in a curved position, and having their outer edges abutting the lower face of the top of the torpedo case.

2. A railway torpedo comprising a body portion, a flap secured to one side of the body portion and having slanting end walls, the said flap carrying at one side a rectangular top of an area less than the body portion, the opposite edge of said top carrying a flap having its walls diverging and a rectangular portion carried by the free edge of the last-mentioned flap and of an area equal to that of the body portion, an explosive compound Within the body-portion and flaps carried by the ends of the body portion, and of a length greater than the open slanting ends of the case and adapted to be folded into the same in a curved position and having their outer edges abutting the lower face of the top of the torpedo case.

3. A railway torpedo, composed of a blank having a body-portion, flaps carried by the body-portion and constructed and arranged to be folded to form an open ended case having the upper face of a length less than that of the body-portion, an explosive compound within the case, said body-portion having flaps at the ends of a length greater than the open ends of the case and adapted to be folded into the same in a curved position, substantially as shown and described.

4. A railway torpedo composed of a blank having at one side flaps constructed and arranged to form an open ended case secured to the upper face of the body portion, an explosive compound within the open ended case and end flaps carried by the ends of the body portion and of a length greater than the end walls of the case and adapted to fold 7 up Within the ends of the open ended case in a curved position against the side Walls thereof and under the top thereof in a curved position.

5. A railway torpedo composed of a blank having at one side flaps constructed and arranged to form an open ended case secured to the upper face of the body portion, a railattaching strap secured to the lower face of the body portion, an explosive compound within the open-ended case and end flaps carried by the ends of the body portion, and of a length greater than the end walls of the case and adapted to fold up within the ends of the open ended case in a curved position against the sides and under the top thereof in a curved position.

6. A railway torpedo comprising a body portion, flaps carried by the body portion and constructed and folded to form an open ended case having a reduced upper face and an explosive compound within the case, and said body portion having flaps at the ends of a length greater than the open ends of the case and adapted to be folded into the same in a curved position and having their outer edges abutting the lower face of the top of the case.

7 A. railway torpedo composed of a blank having a body portion, having two slits, a rail-attaching strap threaded through said slits for securing it thereto, flaps carried by one side of the body portion and constructed and folded to form an open-ended case, an explosive compound within the case, the upper face of the case being shorter than the body portion, a plastic cement composition placed vwithin the open ends of the case against the explosive mixture and said body portion having flaps at the ends of a length greater than the open ends of the case and adapted to be folded into the same in a curved position against the cement, and having their outer edges abutting the lower face of the top of the open-ended case.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
