TRACK-TORPEIDO.
Specification of Letters Patent.
Patented Dec. 4L, JWIW.
, Application filed May 27, 1916. Serial No. 100,259.
To all whom it may concern:
Be it known that I, HUGH WILLIAMSON KELLY, a citizen of the United States, and
' a resident of Trenton, Mercer county, New
Jersey, have invented certain Improvemerits in Track-Torpedoes, of which the following is a specification.
. and Apr. '5, 1916, respectively; the structure constituting my present invention being made in the form of a premolded rubber shell or casing adapted to contain a charge of detonating material; said shell having integral lugs whereby the head of a rail may be gripped in order that the torpedo may be properly positioned with respect to said rail.
In the present structure, the detonating material may be inclosed and confined within a suitable envelop, and the whole may be then introduced into a suitable mold with the desired rubber material and subjected to heat and pressure so as to inclose such charge within a rubber shell having the integral lugs whereby it may be secured to the head of a rail.
A further construction consists in forming the shell over a core whereby a chamber is formed to receive the detonating material; a slit being left to permit the introduction of such detonating material, after which such slit is closed.
A modification of these arrangements is a structure in which a rubber lug carrying strap is formed, adapted to be secured to a shell or casing inclosing and carrying a detonating charge.
These and other features of my invention are more fully described hereinafter, reference being had to the accompanying drawings, in which:
Figure 1, represents a preformed torpedo of the type constituting my present in vention; showing the same in proper position with respect to a rail head.
Fig. 2, is a longitudinal sectional view of the same.
Fig. 3, is an inverted planview of Fig. 2.
Fig. 4, is a perspective view of such torpedo structure illustrating a modificat1on within the scope of my invention.
Fig. 5, is a longitudinal sectional view illustrating the same modified form of tor pedo shown in Fig. 4.
Fig. 6, is a sectional view on the line VI-VI, Fig. 2.
Fig. 7, is a longitudinal sectional view of a torpedo illustrating a further modification within the scope of my invention, and
Fig. 8 is a sectional view on the line VIII-VIII, Fig. 7.
The shell 1, of the torpedo illustrated in Figs. 1, 2, 3 and 6, is a thin-walled structure with the ends beveled as at 2 and the sides as indicated at 8; the base 4 being shaped to conform to the surface of the rail-head, and continuous with the walls of this structure are the rail-engaging lugs 5. In this structure, the charge is disposed within the mold in which the shell is formed; being inclosed in a suitable envelop,'capsule, or other container 6, and the rubber and other material to form the shell of the structure is placed within such mold, and the whole subjected to the necessary heat and pressure whereby a continuous shell with rail-engaging lugs is formed, as illustrated in the drawings.
In the form of structure shown in Figs. 4. and 5, the shell is so molded as to leave an aperture or opening 7 whereby the charge may be inserted in the cavity or chamber formed within the shell, after which such opening may be sealed in any suitable manner. In this arrangement, the detonating material may be put in the shell in the form of a preformed charge, or it may be loose material wrapped in an envelop of suitable size and shape to fill the cavity, such as indicated in Fig. 2, or such detonating material may be introduced in loose condition to substantially fill such cavity. In any instance, the charge should be of such a character as not to disarrange or displace the lower wall of the shell which is adapted to rest upon the rail head and is, to a certain extent, arched, as indicated. The structure shown in Figs. 7 and 8, is initially made in two pieces; the lug-carry- 'ing strip 5 and the charge-carrying casing 1 the two parts being subsequently secured together by any suitable securing or cementing means, and when finished constituting a torpedo of substantially the same type as those illustrated in the other views.
It will be understood that all of the torpedoes are of substantially the same shape and character as illustrated in the perspective view; they are provided with an arched base portion substantially conforming to the surface of the rail, and they are provided with integral rail-engaging lugs whichrmay V have their inner faces roughened by corruga- :.small. P The object is to provide a relatively flexible structure suitable forv the purpose and onerthat Willi-be nonflying underthe detonation of the; charge. The connection .betweenthe' lugspand the shell should be of a relatively better grade of material thanv the shell so as to insure the desired resiliency tandrattthe sameitlme therequired tension Mpon the lugs when they are placed inqthe rail-engaging position.
