HUGH WILLIAMSON KELLY, OF PROVIDENCEQRHODE ISLAND, ASSIGNOR OF ONE-HALF TO, AUBREY LOVE,- OF RIDGEWOOD, 1 TEW JERSEY.

rnooisiss or MAK NG TRACK-TORPEDOES.

T all whom it may concern:

Be it known that I, HUGH "VILLIAMSON KEILY, a citizen of the United States, and

a resident of Providence, Rho'de Island,

have invented Improved Processes of MakingTrack-Torpedoes, of which'the following is a specification.

"My invention relates to track torpedoes of thetype set forth in my Patent Number 1,248,670, dated December 4, 1917, and the object-of my present invention is to form a molded torpedo of rubber or rubber-com taining material with the explosive charge l positioned within the same; sai'd torpedo,

or the molded'shell comprising the same,

having integral lugs for gripping the head of a rail in order that it may be properly positioned with respect to said rail.

According to my present invention, the

detonating or explosive material, whether contained within a suitable'envelop or not, as may be necessary or desirable, is introduced into a suitable mold with the desiredamount of rubber or rubber-containingiinateri'al properly positioned with respect to the same, and then the mold with the'contained material is'subjected to'hea't and pressure so as to produce an integral continuous-walled container or shell having 7 80 the integral lu'gs'whereby it may be secured to? the head of. a rail, and inclosing such detonating charge.

"These and other features of my invention are more fully described hereinafter, 'i 35 referencebeing had to the accompanying drawings, in which:

Figure1, represents one form of molded torpedo'jof the type to Which my invention relates positioned upon a rail head.

to Fig. 4, showing forms of molds in which torpedoes of the shape or type illustrated in Figs. 6 and 7, may be formed.

Figs. 10 and 11, are cross'sectiona'l views similar to Fig. 5, of the molds" shown in Figs. 8 and 9, and

Figs. 12, 13, 14, 15,16 and 17, illustrate other modifications within the scope of my invention.

The shell 1 of the torpedo illustrated in Figs. 1 and 2 at 869., may bea thin-Walled structure, with the ends beveled as at 2, and the sides beveled as indicated at 3; the base 4 being shaped to conform to the surface of the rail-head, with rail-engaging lugs 5 continuous with the walls of the structure.

In forming or making this structure, the charge is disposed within the mold in which the shell is shaped, as shown in Fig. 4, in which the charge 6 is represented as inclosed within a suitable envelop 7, and the rubber or other'material'to formthe shell of the structure is placed within such mold in the space indicated at 8. In some instanceslthe envelop 7 may be omitted. The mold with its inclosures thus prepared is then subjected to the necessary heat and pressure whereby a continuous-Walled shell inclosing the charge and having the railengagin'glngs 5 is formed as a single integral and homogeneous structure, as illustrated in the several views of the drawing". If desired, the charge may be prei'nolded or shaped in the form of a cake 'orblock, and in such instance the envelop or container 7 may be omitted.

In the form of torpedo'shown in Fig. 6,

a broad detonating-chargecontainer 1 is around which thesections of rubber or rubher-containing material are placed.

In the form of-torpedo shownin Fig. 7, a roundedcentral chamber 1 is provided for the detonating charge; said chamber sur mounting the strip or band 'formiiigthe base 4", and the ends of said base are pref erably stiffened by integral bracing members 9. Figs. 9 and 11, show the manner in which this form of torpedo is made and,

as in the other structures referred to, the

detonating charge may be either a premolded block, or contained within a suitable envelop before insertion in the mold.

meansto assist in retaining the same upon the head of a rail.

In some instance it may be desirable to provide the torpedoes with straps '5, long enough to extend under the head of the rail, and in Fig. 12, I have shown a sectional view of a torpedo of this type. Such form of torpedo may be molded in a mold of the character illustrated generally in Figs. 4 and 5; provision being made for the formation of the elongated straps with their ends to underliethe rail heads, and in Fig. 13, I have shown a mold of this type.

It will be understood, of course, that forms of these molded torpedoes may be, if desired, made in'more'than one piece, and in Fig. 14, I have shown a type of a two-part structure in which the parts 11 and 12, are separately molded and the whole then assembled after the detonating material has been set in place. In this form of the torpedo, the member 11 will have rail-engaging lugs 5 of substantially the same type as those illustrated in Figs. 1, 2 and 3; the same being integrally connected with said member 11 which has lugs'or ears 13 whereby it may engage the walls ing section 12. This molded, and the same ceive the charge 6 of detonating material which will be confined in place upon application to the lug-carrying base. If desired,

of the charge-containsection may also be will be hollow to rea cementing body of some nature may be- .employed to connect the parts together or 'tohermetically seal them and thereby protect the detonating material from the ingress of dampness or moisture.

In Fig. 16, I have shown a sectional viewof another form of torpedo which may comprise a tubular member of compressible material. In this form of structure, I may provide a tubular device 15 of rubber, or of any suitable friction fabric having a waterproof wall, and when finished, its ends will be open for the reception of independent lugs 16,. which may be previously molded and which may be attached to the ends of said tubular member in any suitable manner.

For instance, said lugs may be sewed to the ends of the tubular member at 17.

In referring to the shell of the torpedo as made of rubber,

it will be understood, of

course, that what is meant is a rubber-con taining material, the quantity; of rubber in as indicated which may be relatively smalli' The object,

is to provide a relatively"flexibleistructure suitable for the purpose and one that will be non-flying and therefore not dangerous by reason of any onation of the charge.

The connection between the lugs and the base of the shell or container in all forms of flying parts under the det- V my improved structure are preferably of a relatively better grade of material than that comprising the container, so" as to insure the desired resiliency and at the same time the required tension upon the lugs 5 when they are placed in a rail-engaging position.

As this application possesses matter in common with an application filed by me May 27, l916,..Serial Number 100,259, it. is v to be treated as a continuation of said prior application as far as the common subject matter is concerned. .I claim: V V f I 1.
