FRANK DUTCHER, OF VERSAILLES, PENNSYLVANIA.

TRACK-FASTENER FOR FIBROUS FiAlLFiOAD-TORPED OES.

Specification of Letters Patent.

Patented Oct. 24, 1905.

Application filed August 17, 1905. Serial N- 274,595.

:0 This invention relates to improvements in track-fasteners for fibrous railroad-torpedoes, and the object of which is to securely and effi- "ciently attach a spring-fastening to a fibrous or paper torpedoj As is well known by those skilled in this art, a spring-fastening for a torpedo exerts considerable pressure tending tobreak it away from the torpedo when the free ends or arms of the spring are forced apart and when they are released to grab the It has therefore been found difficult to attach a spring fastening to a fibrous or paper torpedo-case in a manner which is both simple and eificient and which will prevent it from being torn away from the :5 torpedo when the spring is extended and suddenly released for attaching it to the tread of a railroad-rail. It is also well known to those skilled in this art that torpedoes are provided with. spring-fastenings, more particularly for ;o the purpose of enabling them to be placed upon the tread of the rail through the medium of well-known forms of torpedo-placers from the rear end of a moving train. This mode of attachment also tends to break away ,5 the fastening from the torpedo, as will be readily appreciated.

By means of my present invention I am enabled to attach a spring-fastening to a fibrous or paper torpedo in a manner which will pre- .0 vent it from being broken away under the strains and jerks to which such a fastening is subjected in the application of the torpedo to a railroad-rail.

In the accompanying drawings, Figure 1 is .5 a perspective View of my invention applied to a railroad-rail, the fibrous or paper case being broken away to show in section. Fig. 2 is a transverse sectional view of the same, showing it applied to a railroad-rail. Fig. 3

ing member 3, the two members being in an inverted position, as readily shown. For the purpose of further strengthening the torpedocase I place the containing-receptacle composed of the members 1 and 2 in a larger cupshaped inclosing member 4:, though I desire it to be understood that this member 4, while preferable, is not absolutely necessary to my present invention. Also for the purpose of strengthening the torpedo and holding the flanges of the paper or fibrous cup-shaped members in proper position and preventing them from spreading and also for the purpose of offering resistance to the explosive force of the detonating compound Isurround the edge of the case with a combined holding and strengthening band 5. I desire it to be understood, however, that this surrounding holding and strengthening band forms no part of my present invention. This feature is made the subject of a copending application.

My presentimprovement relates to the manner of attaching the spring-fastening 6 to the torpedo; and it consists in placing in one of the members of the torpedo-case a metallic disk 7 and passing a rivet 8 through the case, the metallic disk, and the fastening 6, and thus riveting them firmly together. I prefer to have the metallic plate in the outer inclosing member 4, though, as before stated, it may be placed within one of the other members of the case Without departing from the spirit and scope of my present invention.

From the foregoing it will be observed that the disk 7 may be placed in either ofthe members 2, 3, or 4; but preferably it is either in the member 3 or A, the member 2 being the containing member proper, and the member 3 an inclosing member, and the member 4 an additional inclosing member. The particular reason for connecting the strap 6 to one of the inclosing members 3 or 4 is that it will leave the containing member 2 entirely freeand unencumbered with the strap for filling purposesthat is to say, the person assembling the torpedo can more readily fill the containing member if the strap is not attached to it than it is possible to do if the strap is attached to it. As far as I am aware I am the first one to connect a rail-engaging strap to the outer member of a torpedo, whereby the foregoing advantages are obtained. This metallic disk or plate 7 ispreferably made of a size to fit within the members of the case containing it, though this may be Varied Without departing from the spirit and scope of my invention, the broad idea of which is to unite the spring to the fibrous or paper case through the medium of a metallic or hard substance member placed within one member of the case, the spring placed upon the outside of the case, and the rivet passing through the spring, the case, and the plate and riveting them firmly and securely together.

From the foregoing it will be seen that I effect a fastening in such a manner that it will not be separated or torn away from the paper or fibrous case, and at the same time the parts are so arranged that when the torpedo explodes no part of the metal portion of the torpedo will be dismembered or segregated and caused to fly, and thus probably cause injury to persons standing near.

It will be understood that the object of the fibrous or paper torpedo-case is to provide a torpedo of such a material that when it eX- plodes there are no metal parts to fly and strike persons and cause injury, which is true of the metallic torpedoes, and in order to have the paper or fibrous torpedo retain the non-flying and non-injurious character the parts which unite the spring must be so arranged as to prevent them from flying under the explosion of the detonating material. I accomplish this in a very simple and efficient manner by the construction which I herein show and have described.

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

1. In a railroad-torpedo, the combination of a fibrous case or container for the detonating material, a plate ormember within the case, a spring-clasp at the outer side of the case, and a rivet passing through the spring, the case, and the plate and uniting the parts together.

2. In a railroad-torpedo, the combination of a containing case, comprising telescoping fibrous members, one of said members containing at its inner side a disk or plate, a spring-clasp at the outer side of the case, and a rivet passing through the spring, the case and the plate, and uniting the parts together.

' 3. In a railroad-torpedo, the combination of a containing-case, a plate within the case, a spring located outside of the case, and a rivet passing through the spring, the case and uniting the parts together.

4. In a railroad-torpedo, the combination of a containing-case, aplate within the case of a shape corresponding to the bottom of the case,

case, and the plate and serving to unite the parts together.

6. In a railroad-torpedo, the combination of acontaining-case, a surrounding inclosing case for the containing-case, a plate within the surrounding case, a rail-engaging memberoutside of the inclosing case, and arivet passing through the rail-engaging member, the inclosing case, and the plate and serving to unite the parts together.

7. In a railroad-torpedo, the combination of a fibrous containing-case, a plate within the case, a rail-engaging member outside of the case, and means for uniting the plate and the rail-engaging member and holding theparts together.

8. An improved railway-torpedo, consisting of a containing-case and an inclosing case, and a rail-engaging strap connected to the inclosing case.

9. An improved railway-torpedo, comprising a case composed of a containing member, and an inclosing member telescoping the containing member, and a strap-fastening carried by the inclosing member.

10. An improved fibrous railway-torpedo, consisting of a fibrous case which comprises a containing member and an inclosing member, and a rail-engaging strap connected to the inclosing member.

In testimony whereof I afiix my signature in presence of two witnesses.

FRANK DUTGHER.
