In the accompanying drawings like letters indicate like parts. Fig. l is a top View of the tie in perspective, Fig. 2 is a view in perspective of the fastener, Fig. 3 is a cross section on line 1, :2, looking in the direction of the arrow, Fig. at is a cross section on line 3, 4 looking in the dire ction of the arrows, Fig. 5 is a cross section on line 5, 6 looking in the direction of the arrows, Fig. 6 is a side view showing the attached rail in section, Fig. 7 is a top view of the tie with the rail base indi cated.

Referrin to Fig. 1, my tie is preferably made from a piece of metal plate bent as shown. Ithas flat bearing surfaces A and A adapted to rest upon the roadbed and carry the weight, and a central rib' B, the purpose of which is to strengthen the tie. The size and shape of B may be regulated so as to permit the desired degree of spring or yield to the passage of the train. It is not essential to my invention that-the tie be formed by folding sheet metal. The tie constitutes in effect a T beam and it may be constructed in any way in which such beams are made. The

roadbed will be tamped under A, A in the usual way to provide a firm support.

The method by which the rail is secured to the tie is as follows: On each side of each rail a part of the tie is stamped up into the position shown at C, C C and C leaving slots as shown at 0, 0 At the outside end of the slot away from the rail it is widened and the rolled-up part is cut out in order to make an entering opening for the fastener lugs f and 7. The fastener F is entered through the opening a, a a and is pushed along until the point of it f is over the rail as shown in Fig. 6 and the tail of it f is under the tie. The pointof the fastener may be beaten down on the flange of the rail. The fastener thus secures the rail to the tie. The bent down m pieces D, D (Z, (Z are guides, serving to hold the tail of the fastener f against the under they would not be necessary. The entire desurface of thetie and the central rib, the fastener having been pushed ordriven forward into the position shown in Fig. 6.. The rolledsup piece C is thereupon hammered down behind the fasteneras shown at Fig. 7 thereby holding the fastener F in position and preventing it from working away from the rail. The lugs, f f, on the fastener F are for the purpose of giving additional strength against an upward @or rolling stress on the? rail. 'Thecenter rib B is cut as shown at .7),

If to receive lug f These lugs are not an essential part of my invention. In light work or with extra heavy fasteners and ties vice is duplicated on each side of each rail. Toremove the fasten-er, a plowshaped piece is entered at the opening, 66,66 and driven forward, nclling up the retaining piece 0 into its original position and permitting the fast en-er F to be withdrawn. In this way the tie can be used an indefinite number of times.

Obviously ties'embodying my invention may be constructed in many different forms. H The central rib may be omitted and the tie made as a flat plate. The fastener may be made inmany different forms. The metal may bebent up on each side of the slot instead of only on one side and the edges of the bent-up sides may be serrated or slit to permit better engagement with the fastener. The tie may be used in connection with a concrete or wood base. The essential feature of my invention is the slot with its bent-up side piece permitting a fastener to be en-- tered and to engage the under side of the tie and the upper surface of the flange of the rail, said fastener being held in place by beating down the bent-up side of the slot.

Having thus described my said invention, I claim, 1 r V 1. A metal railroad tie having on its upper surface a slot with a bent-up side integral with the tie, a fastener adapted to enter said slot and to engage said tie and the rail and 9 hold the two together, said fastener being held in position against the railby forcing down against it the bent-up side of said slot. 2. A metal railroad tie having a flat top adapted to rest on the roadbed and a vertical rib, said top being provided With slots having up-turned sides, fasteners adapted to enter said slots and to engage the under surface of the tie and the upper surface of the rail flange, said fasteners being held in position by forcing down against them the bentup sides of the slots.

3. A railroad tie made of metal plate pressed into a central rib With horizontal flanges adapted to rest upon the roadbed, slots in said horizontal flanges having bentup sides, fasteners adapted to enter said slots and engage the under surface of the metal tie and the upper surface of the rail flangeand to be held in position by forcing down the bent-up edges of said slots behind said fasteners.

4. A railroad tie made of metal plate pressed into a central rib With horizontal flanges adapted to rest upon the roadbed,

slots in said horizontal flanges having bentup sides, fasteners adapted to enter said slots and engage the under surface of the metal tie and the upper surface of the rail flange and to be h ld in position by forcing down the bent-up edges of said slots behind said fasteners, and guide-plates adapted to' en- I gage the tail of said fasteners.

5. A metal railroad tie having on the upper face thereof a protruding lug integral with said tie and adapted to be forced into contact with a fastener and hold said fastener in position, and a fastener adapted to engage the rail and hold the same in position and to be retained in place by said lug when the latter has been forced into contact with it.
