IMPROVEMENT IN PORTABLE RAILROAD-TRACKS.

Specification forming part of Letters Patent No. 221,817, dated November 18, 1879; application filed August 23, 1879.

To all whom it may concern:

Be it known that I, ALFRED HEYN, of the city, county, and State of New York, have invented certain new and useful Improvements in Portable Railroad-Tracks, of which the following is a specification.

In the accompanying drawings, Figure 1 represents a top view of my improved portable railroad-track, shown with interlocking sections. Fig. 2 is a top view of the same, with sections detached; and Fig. 3 is a detail vertical longitudinal section on linezr as, Fig. 1.

Similar letters of reference indicate corresponding parts.

This invention relates to improvements in portable railroad-tracks, by which not only a more reliable interlocking of the sections, but also, at the same time, an alternating railjoint, is obtained.

The invention consists of a portable railroadtrack made in sections, the rails of each section being extended at diagonally-opposite ends, while the other'rail ends extend only to the middle of the tie. Each section has a lockingpiece, adjoining the shorter rail end, which interlocks with the elongated rail end of the adjoining section. The end tie of each section has also a second binding-piece, that bears on the interlocking-piece of the adjoining section to prevent the dislocation of the section.

Referring to the drawings, A A represent the sections of my improved portable railroadtrack. Each section A is constructed of crossties at a, which are, preferably, of iron of suitable cross-section, and of rails 12 I), riveted to the erossties. The end ties a a are wider than the intermediate ties for giving a better support for the meeting ends of the rails.

The rails of each section A are extended at diagonally-opposite ends beyond the end tie to a certain distance, while the other rails stop short at the middle of the end ties. The

sections when connected form thus a continuous line of track, in which the rails alternately break joint, so as to facilitate .the running of the rolling-stock on the track.

Each section A is provided, adjoining the shorter railends, with looking pieces B, which are riveted firmly to the end tie. These looking-pieces B are slightly rounded off at the side adjoining the rail, to allow the track-sections to be laid at an angle toward each other when rounding curves. They are also slightly bent upward at the ends, as shown in Fig. 8, to facilitate the ready pushing together and connecting of the sections. The lockin g-pieces of the tracksections form, with the elongated rails of the sections, a rigid and reliable connection of the sections when the weight passes over the same, first at one side and then at the other, owing to the alternating jointsof the rails. The interlocking of the sections equalizes the weight and renders the track more secure and firm.

Each end tie has, furthermore, a binding piece, 0, at such distance from the elongated rail that the locking-piece B may freely pass in. It is then retained by the angular side of the binding-piece G, and thereby the sidewise dislocation of the sections prevented. sections are thus connected, so as to resist the vertical pressure of the weight as well as longitudinal and lateral strains, and form thereby a smooth and reliable interlocking track.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- As an improvement in portable railroad The
