METAL TIE FOR RAILWAY-TRACKS.

SPECIFICATION formingpart of Letters Patent No. 497,954, dated May 23, 1893.

Application filed May 23,1892- Sen'al No. 434,067. (No model.)

To all whom it may concern.-

Be it known that I, MATHEW FITZGERALD, of the city of Troy, county of Rensselaer, and State of New York, have invented a new and useful Improvement in Metal Ties for Railway-Tracks, of which the following is a specification.

My invention relates to an improvement in.

metal ties for railway tracks, and my invention has for its object an improved form of tie to adapt the blank from which the latter is made to be rolled out from steel or iron, and my invention consists (as will be more fully detailed hereinafter in connection with its illustration) and as set forth in the claims of a rail tie formed from metal with vertical sides and aflat top, and having its sides near the ends notched out, so that the ends of the blank may be folded back on the latter to inclose and produce the ends of the tie.

My invention also consists (as will be more fully set forth hereinafter in connection with its illustration) in the combination with a metallic tie having vertical sides, fiat top and turned in ends of a fish-plate arranged at each end of the tie near its ends with said fishplate having turned down ends adapted to be secured to the tie at the sides and top.

Accompanying this specification to form a part of it there is a sheet of drawings containing five figures illustrating my invention, with the same designation of parts by letter reference used in all of them.

Of these illustrations Figure 1 is a perspective of a tie blank that has been rolled and notched at the sides from which to form a tie. Fig. 2 is a perspective of one of the ends of the blank shown at Fig. I, after having been partly folded back on itself to produce the end of the tie. Fig. 3 shows one end of the tie after the folding illustrated at Fig. 2 is completed. This figure shows also a fishplate connected thereto. Fig. 4 shows a modification in which the fish-plate is connected to the tie inside of its end fold, and Fig. 5 is a section taken on the line 00, 0c, of Fig. 4:.

The letter S designates the sides of the tie, T its top, and preferably the sides are made to be at right angles to the top, as the blank form B is rolled.

The letters N and I designate notches that are cut in the opposite sides of the blank on which each of the outer ends are turned back on the body-part, so as to lap past the sides of the blank and underlap the top thereat, to form the ends of the tie shown at Figs. 2, 3 and at.

The letter F designates a fish-plate made with down turned ends E, E, and the letter I) designates a bolt made to be passed through each of the down turned ends of the fish-plates and through the tie sides as shown at Fig. 4, or through the lapping ends of the tie sides and the latter as shown at Fig. 3.

The letter Z) designates bolts made to connect the top of the fish-plate with the tie. Each of these fish-plates is made with a flange F that overhangs the tie top sufliciently to receive the side of the rail base when entered therein.

The blank is rolled into the form shown at Fig. 1, and then the notches N and I are cut out from the sides. When bent to produce the ends of the tie, the parts 72, between the notches N and I pass outside of the sides proper, while the top of the blank T, where between the notches forms the inclosed end of the tie, and the sides m, where beyond the notches when bent, are on the outside of the sides proper at their ends e, and the top part p, where beyond the notches produces the base for the tie end at L, in which position as bent the parts are swaged so as to make close contact where lapping, and in position as shown at Figs. 3 and 4..

The letter T designates tamping places cut out of the top T, for the insertion of tamping or ballasting material, and the ramming of the latterby a tamping implement.

As thus made a strong tie is produced and it may be rolled from steel, semi-steel or iron.

While I have shown a form of fish-plate to receive the outside edge of the rail-base, any well known form of fish-plate may be used in connection with my improved tie.

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

l. A metallic tie for rail tracks, having a hollow interior, that is open on its under side,

down and then up inwardly to produce the ends and base support for the ends of the tie; of a fish-plate having down turned ends, and adapted to be secured to the sides of the tie by bolts, substantially as shown and described. Signed at Troy, New York, this 22d day of May, 1891,and in the presence of the two witnesses whose names are hereto written.

MATHEW FITZGERALD.
