FIIBER-CASE RAILWAY-TORPEDQ Specification of Letters Patent.

Patented J an. 2, 1917.

To all whom it may concern:

Be it known that I, FRANK Dn'ronnn, a citizen of the United States, residing at Versailles, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Fiber- Case Railway-Torpedoes, of which the following is a specification, reference being hadtherein to the accompanying drawing.

My invention relates to improvements in fiber case railway torpedoes.

The object of my invention is to provide a torpedo of this character in which all metal for closing the case and holding the strap is dispensed with so that there are no metal parts to fly to injure by-standers, and having tapering ends so that the torpedo is less liable to be knocked off the track by the car wheels.

Another object of my invention is to provide a simple, cheap and effective torpedo having certain details of structure and com binatic-n of parts hereinafter more fully set forth.

In the accompanying drawings, Figure 1 is a perspective view of my improved torpedo. Fig. 2 is a bottom perspective view of Fig. 1. Fig. 3 is a longitudinal sectional view taken on the line 3-3 of Fig. 1. Fig. 1 is a bottom perspective view of a. modified form of torpedo. Fig. 5 is a transverse sectional view of Fig. 3.

Referring now to the drawings, 1 represents the outer case of my improved torpedo and which is preferably made of a tube cut into the proper length and pressed down flat as shown in Figs. 1 and 2 of the drawings and having its ends formed with folds 2 also clearly shown in Figs. 1 and 2 of the drawing. The bottom 3 of the case is provided adjacent its edges with the slits a and 5, and the portion 6 between the slits a and 5 is pressed downwardly and passing through said downwardly pressed portion of the bottom, and through the slits is the rail-attaching clip or strap 7, whereby the same is readily secured to the torpedo. The explosive compound 8 is preferably in tablet form and is surrounded by a wrapper 9 which has the extended portions 10 extending within the folded ends of the case 1 and whereby there is a double covering for the explosive compound as fully shown in Fig. 3 of the drawing. It will be understood that the wrapper 9 has its ends open and when the ends of the case 1 are folded, the wrapper necessarily is folded therewith and tightly closes the same. I

Passing through the folded ends of the case 1 are two rows of stitching 11 and 12 which tightly closes the ends of'the case. These two rows of stitching also pass through the extended ends 10 of the wrapper 9 and tightly seal the Wrapper. The folded ends of the torpedo case 1 are dipped into a waterproof composition 13 which tightly seals the ends of the case and also the folded ends 10 of the wrapper 9 and absolutely prevents any moisture entering either the folded ends of the wrapper or the case. This waterproof composition also enters the openings formed by the two rows of stitching, and prevents any moisture entering the case 1 or the wrapper 9. By this construction and arrangement of parts it will be 'seen that I have provided an absolutely water-tight case having a double thickness and in which both inner and outer casings are simultaneously closed by a single means such as the stitching. It might be found necessary to dip the whole torpedo in a waterproof composition which would tightly seal the slits 1 and 5 in the lower face, and absolutely prevent any moisture entering the outer case around the wrapper.

1n the modification shown in Fig. 4 of the drawing the case 1 is constructed in the same manner as that shown in Figs. 1, 2 and 3, but in order to prevent the slitting or piercing of the case 1, I have provided an additional tube 11 which is of a length approximately that of the explosive compound '8, and tightly fits around the outer case 1. This additional tube 11 is provided with slits 15 and 16 having the portion 17 bulged downwardly and forming a space through which the rail-attaching clip 18 passes and whereby the rail-a taching strap or clip does not enter the outer case 1 of the torpedo and absolutely prevents any moisture entering the outer case on'the outside of the wrapper 8. After the torpedo is constructed in the manner shown in Figs. at and 5 the whole torpedo is waterproofed with shellac or other waterproof composition which firmly locks the tube 1 1 on the case 1 and at the same time additionally seals the outer folded ends of the case 1 to form a more water-tight case.

The object of forming tapered'ends for the wrapper and tube is to present a relatively thin edge for the wheel of the locomotive or car to run on thus avoiding a thick abrupt edge for the engagement of the car Wheel which might force the torpedo oil' the track.

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

l. A railway torpedo comprising an explosive tablet, a wrapper around the tablet in tubular form with open ends, an open ended tube surrounding the tubular wrapper and of substantially the same length, the wrapper and tube having their ends extending beyond the explosive and flattened, and a stitching extending through the ends of the wrapper and tube uniting them and closing the open ends of both the tubular I wrapper and the tube.

2. A fiber case railway torpedo comprising an explosive tablet, a wrapper therearound in tubular form with open ends, an open end tube inclosing the tubular wrapper, the ends of the Wrapper and tube extending beyond the explosive substantially the same distance, and the edges of the tube and the wrapper folded inward to form extended tapered ends, and stitching passing through the ends of the tube and the tubular wrapper and closing their open ends.

3. A fiber case railway torpedo, comprising a flattened tube, an explosive tablet Copies of this patent may be obtained for five cents each, by addressing the of the tube beyond the explosive tablet, a

tube tightly fitting the first-mentioned tube and of a length shorter than the same, a rail attaching strap carried by the second tube, and means for holding the second tube on the first-mentioned tube, substantially as shown and described.

5. A fiber case railway torpedo comprising a flattened tube, an explosive tablet within the tube, the ends of the tube beyond the end of the explosive tablet folded and flattened, a stitching passing through the fiat tened folded ends of the tube, a second tube tightly fitting the first tube, and of a length less than the same, a rail-attaching strap carried by the second tube, and a waterproof composition covering the entire torpedo first and securing the second tube to the first tube, substantially as shown.

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