THOMAS F. KRAJEWSKI, OF NEW YORK, N. Y.

PORTAB LE RAI LWAY-TRAC K.

SPECIFICATION forming' part of Letters Patent No. 235,786, dated December 21, 1880. Application filed August 4, 1880. (No model.)

To all whom it may concern:

Beit known that I, THOMAS F. KRAJEW- sKI, of the city, county, and State of New York, have invented a certain new and useful Improvement in Portable Railway-Tracks, of which the following is a specification.

In a portable railway-track it is of great importance that therail-sections should be so joined together that vertical and lateral movelnent of one section independent of the adjacent section will be prevented; and it is also of great importance that the joints between the sections should be so constructed that the sections can all be readily detached from each other and taken up when it is desired to move the track, or so that one section can be taken up and readily replaced by another, 'which may be a switch, a crossing, or a frog.

My invention consists in the combination, with the abutting ends of two adjacent railsections in a portable railway-track, of two fish-plates secured one to the vrail and cross bar of one section upon one side of the rail and the other to the rail and cross-bar of the other section upon the other side of the rail, each fish-plate projecting beyond the end of the rail-section to which it is secured and overlapping and bearing against the rail and cross-bar of the other section, but otherwise havin g no connection therewith.

In the accompanying drawings, Figure l represents a plan of a portion of a portable railway-track embodying my invention. Fig. 2 represents a side view of one ofthe ishjoints of said track upon a larger scale. Fig. 3 represents a transverse section upon the dotted line w m, Fig. 2, and Fig. 4 represents a partly-sectional plan of the joint.

Similar letters of reference designate corresponding parts in all the iigures.

A A designate adjacentV sections of rail, which are placed end to end, and the abutting ends of which are to be united. The rails of the sections are secured in the usual manner by bolt-ing or riveting to cross-bars. The end cross-bars, B B', are placed in close proximity to the joint, and secured to the rails by being bolted or riveted to the angle fish-plates O C', which are also bolted or riveted to the rails, as clearly shownV in the drawings.

As clearly shown, the fish-plates C are secured to the rails A and cross-bar B, and the fish-plates O to the rails A and cross-bar B by means of bolts, or permanently secured thereto by means of rivets b, as here shown. The fish-plates secured to the ends of one tracksection overlap and bear against the rails and the cross bar of the other section, but otherwise have no connection therewith, thus transmitting the pressure from one section directly to the rail and cross-bar of the following section.

In order to enable a rail-section to be easily disconnected from a line of connected sections by simply raising it at the joint, I preferably make the projecting ends of the fish-plates inclined or slanted on their upper or top edges, as clearly shown at o in Fig. 2.

In order to provide for laying straight sec tions of track around a curve, the projecting ends of the base or horizontally-extending portion of each fish-plate is slanted or dared outwardly, as shown particularly at c in Fig. 4, so as to permit the adjacent rails to be laid at a slight angle to each other.

[t will be also noticed that while the fishy plate at one end of the rail-section is secured to the inner side of the rail, that of the abutting rail of the following section is secured on its outside, as shown in Figs. l and 4. This arrangement, Which has been called out by this special manner of joining the sections, has this advantage, that the pressure of one section upon the other is transmitted alikethat is, by means of a fish-plate pressing upon the rail and cross-bar, there being no difference whether this action is on the outside or inside of the rail.

It will be seen that by my invention I provide for making a strong yet iiexible joint for portable track-sections, the angle sh-plate being itself a strong form of joint, and which, being secured between the head of the rail and its flange, relieves the rivets from the greatest portion of strain on them, andadmits at the same time of securing solidly the crossbar to the rail, which otherwise is not easy to effect on account of the small dimensions of the rail.

, What I claim as my invention, and desire to secure by Letters Patent, is-

The combination, with the abutting ends of two adjacent rail-sections in a portable raill the rail and cross-bar of the other section, but Way-track, of two fish-plates secured one to otherwisehaving no oonneetiontherewith,sub- Io the rail and cross-bar of one section upon one stantially as and for the purpose specified.
