Specification of Letters Patent. Patented Jan, 19, 1915,
(Brig-final application filed April 4, 1912, Serial No. 688,572. Divided and. this application filed June 18, 1914..
Serial No. 845,910.
vent persons being injured by flying particles' of the case when the torpedo explodes.
This case is a divisional application of my application for railway signal torpedoes Serial No. 688,572, filed April 1, 1912.
My present invention consists in providing a cloth wrapping for a substantially rectangular open-ended tubular explosive containin case; to close the open ends of the case by the cloth wrapping; to strengthen the paper case of the cloth wrapping, and to. secure a metallic strap-carrying clip to the case and the cloth wrapping carried thereby.
The object of my invention is to provide an efficient and cheap non-metallic case torpedo, which will have its paper case strengthened and the explosive within the case protected, the cloth wrapping -rnore effectually withstanding the wear in the handling of the torpedo than the exposed paper of the case. p
A further object of my invention is to so construct a cloth wrapped non-metallic torpedo by the use of special tools and appliances that it is adapted to have a metallic strap-carrying clip clamped thereto.
In the accompanying drawings: Figure 1 is a perspective view of my improved torpedo showing it constructed with a metal strap-carrying clip and in position on a railway-rail. Fig. 2 is a sectional View on the line 2-2 of Fig. 1. Fig. 3 is a sectional view'on the line 83 of Fig. 1. Fig. 4; is a perspective view of the parts of the torpedo in separated relation showing the mannerof constructing the torpedo. Fig. 5 is an edge view of the torpedo and a section of the tools used for closing the cloth Wrapping tight when a metal strap-carrying clip is to be used.
Referring now to the drawings in which like reference characters denote the same parts, 1 is a substantially r ctangular openended tubular case-in which the xplosive compound 2 is placed. This explosive compound is in the form of a tablet of a size to fit within the case 1. A paper plate 8 is constructed preferably of a size corresponding to the external size of the bottom of the case 1 to which it is applied. A piece of cloth 7 is provided which is of a length sufficient to wrap the top, bottom, and ends of the tubular explosive containing case 1. The cloth is coated with suitable cement before it is applied and is then pressed around the case. It is of a width corresponding to the length of the tubular case 1. The paper plate 3, above-referred to, extends beyond the edge of the case 1 as shown at 3. Another piece of cloth 8 is provided of a width corresponding to the width of the case 1 and of a length suflicient to pass twice around the .case and the projecting edges of the plate3 longitudinally. This piece of cloth is also coated with cement before it is applied and is wrapped around the case and afterward pressed down on the projecting ends or flanges 3 of the plate 3, as shown in Fig. 5, by means of suitably shaped pressed dies 10 and 11. To afford sufficient cloth to enable it to be pressed down along the edge of the case 1, as shown at 1, Figs. 3 and 5, a suitable pronged instruent 12 has its ends 13 placed outside of the ends of the case 1, as shown in Fig. 1, to enable the cloth to be tightly wrapped around the torpedo, and to provide sufficient cloth to enable it to be pressed down as shown in Fig. 5. This pressing, of course, is done before the cement on the cloth 8 has become hardened.
The construction of the metal clip 14: which receives a spring strap 17 and the construction of the strap are. shown in a copending application and a specific interlocking construction of a strap and clip form no part of my present invention and need not be described herein. The edges 15 of the clip 14 are turned upward, as shown in Fig. 8, and then thewrapped torpedo is placed between these bent edges and the edges clipped down on the projecting edges of the torpedo as shown in Figs. 1 and 3. 7
Having thus described my invention what I claim and desire to secure by Letters Patent is: I
1. A railway signal torpedo comprising a rectangular open-ended paper-explosive containing case, a plate secured to the under side thereof and having two edges projecting beyond the two edges of the case, a strip of cloth wrapped and cemented around the case and the projecting edges of the plate, the cloth presed against the projecting edges of the plate and the adjacent edges of the case, a second strip of cloth wrapped around the case at right angles to the first said strip, a metal clip applied to the under side of the torpedo and clamped around the cloth-wrapped projecting edges of the plate, and a rail-engagingstrap attached to the torpedo.
2. A railway signal torpedo comprising an open-ended tubular explosive containing case, a plate secured to the underside thereof and having two edges projecting beyond the two edges of the case, a strip of cloth wrapped and cemented around the case and the projecting edges oi the plate, and a metal clip applied to the under side of the torpedo and clamped around the cloth-wrapped projecting edges of the plate, and a rail-engag ing strap carried by the said clip.
3. A railway signal torpedo comprising a paper-explosive containing case, a plate at the bottom of the said case and projecting beyond two edges of the case, a strip of cloth wrapped and cemented around the case and projecting edges of the plate, and a metal clip applied to the under side of the torpedo and clamped around the cloth wrapped projecting edges of the plate, and a rail-engaging strap carried by the said clip.
4. A railway signal torpedo comprising a paper explosive containing case, a plate secured to the under side thereof and having two edges projecting beyond the edges of the case, wrappings of cloth around the case and the projecting edges of the plate and a wrapping around the case at right angles to the first said wrapping, and a metal clip applied to the under side of the torpedo and clamped around the cloth wrapped projecting edges of the plate, and a rail engaging strap attached to the torpedo.
5. A railway signal torpedo, comprising an open ended tubular explosive containing case, a plate secured to the under side thereof and having two edges projecting beyond the two edges of the case, a strip of cloth rapped and cemented around the case and the projecting edges of the plate, and a metal clip applied to the under side of torpedo and clamped around the clothwrapped projecting edges ofthe plat and a a rail-engag1ng strap attached to vthe torpedo.
In testimony whereof I hereunto atlix my signature in the presence of two witnesses.
