FRANK DUTCHER, OF VERSAILLES, PENNSYLVANIA, ASSIGNOR TO CENTRAL RAILWAY SIGNAL COMPANY, OF PITTSBURGH, PENNSYLVANIA, A CORPORATION OF NEW JERSEY.

RAILWAY SIGN AL-TORPEDO.

Specification of Letters Patent.

Patented J une 19, 1917.

Application filed September 21, 1916; 7 Serial No. 121,459.

To all whom it may concern:

Be it known that I, FRANK DUTOI-IER, 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 Railway Signal-Torpedoes, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in railway signal torpedoes, and pertains to a particular construction of torpedo made up of three members, all of which will be described hereinafter and particularly point ed out in the claim.

In the accompanying drawings Figure 1 is a. perspective view of a torpedo embodying my invention.

' Fig. 2 is a vertical sectional View taken through the center of Fig. 1.

Fig. 3 is a perspective view showing the parts in separate relation.

Fig. 4 is a sectional view showing a slight modification.

The main or body member 1 is made hatshaped in form with the top or crown portion 2, the vertical portion 3 and the horizontal or brim portion 4. This member forms the top of the torpedo and is composed of paper or fibrous material. An inner cup-shaped member 5 receives an eX- plosive tablet 6, of a size fitting within the member 5, and this member 5 with its explosive tablet is placed within the main or body portion 1, as clearly shown in Fig. 2. A third outer and larger cup-shaped member 7 is of a circumference sufficient to embrace the flange or brim portion 4 of the member 1 and its vertical flange portion is turned inward over the flange or brim portion 4 and cemented thereto. This serves to hold the three parts of the torpedo together with the explosive therein. In cementing the parts the inside of the member 7, together with the inside of the flange S will be painted with proper cement and also the flange or brim portion 4 similarly treated with waterproof cement. WVhen the parts are placed together, the flange 8 of the member 7 stands at right angles to its bottom, as shown in Fig. 3. It is then crimped inward and down upon the flange 4, as shown in Fig. 1, the cement serving to hold it in unite the parts.

The member 7 not only serves to unite the parts of the torpedo, but also serves as means for attaching a rail-engaging strap 9, by providing it with openings 10 through which the strap is threaded before the parts are placed together.

. A torpedo thus formed has a wide extendproduces a fiber top torpedo of novel specific construction.

In the construction of the torpedo shown in Figs. 1, 2 and 3, all of the parts of the case are made of suitable paper or fiber. thus constituting a fiber torpedo. A

In torpedoes the part which flies most is the top owing to the fact that the bottom is in contact with the rail, and in Fig. 4, I have shown the bottom portion 7 made of metal and, in this instance, the turned over flange 8 is narrower than the turned over flange of the paper or fiber member 7. The principal object of making the bottom member of metal is to provide for the attachment of a spring rail-engaging clip 9, which needs a stronger means of attachment than the lead strap 9, shown in Figs. 1, 2 and 3.

In torpedo here shown the width of the that position and thus flange 4 is greater than the height of the crown portion of the member 1, thus providing an extending flange to be gripped by the wheel of the car, to prevent the torpedo from being knocked off the rail by striking the high or central portion of the torpedo in advance of engaging the surrgunding horizontal flange or portion there- 0 Having thus described my invention, what I claim and desire to secure by Letters Patent is A railway signal torpedo comprising an inverted cup-shaped member having its walls at right angles to each other,-the lower edge of the vertical wall extending outwardly to form a lateral flange, a second cup-shaped member fitting within the firstmentioned cup-shaped member, an explosive compound in tablet form within the second cup-shaped. member, the vertical wall of the second member being of a length to engage the top Wall of the first mentioned member to bring the horizontal Wall thereof in the same plane with the lateral flange of the firstmenti0ned cup-shaped member, a third 3 cup-shaped member of a size to receive the flange and a rail engaging strap carried 10 by the third cup-shaped member.

In testimony whereof I hereunto aflix my signature in the presence of two Witnesses. FRANK DUTGHER.
