STEEL RAILWAY-TIE.

.SEECIFICATION forming part of Letters Patent No. 718,568, dated January 13, 1903.l

Application filed July 7, 1902. Serial No. 114,69@ (No model.)

To @ZZ whom it may concern:

Be it known that we,-ELAM M. DENNY and JOHN S. MAXWELL, citizens of the United States, residing at Greencastle, in the county of Putnam andState of Indiana, have invented a new'and useful Steel Railway-Tie, of which the following is a specication.

'Our invention relates to improvements in steel railway-ties, the objects being, iirst, to provide a tie of such shape (or outline) as to admit of the ballast being conveniently and properly tamped under it; second, to provide' a tie constructed in such a manner as to prevent the tie from slipping longitudinally on the road-bed; third, to provide a tie with steel fastenings of such shape as to retain the rails securely in their proper positions and at the same time to strengthen the tie by bracing the sides and to aid in supporting the Weight; fourth,to provide a tie of such construction as to secure the requisite strength with the leastweight of material. We a-ttain these objects by the mechanism illustrated in the accompanying drawings, in Which-- Figure 1 is a perspective View of a section of the tie, a section of a rail, and a partial View of the fastening; Fig. 2, a perspective View of the fastening; Fig. 3, a plan View of some more than half the length of the tie, extending from one end beyond the middle; and Fig. 4, a side' elevationof a portion of the middle of the tie, showing corrugated lugs projecting downwardinto the ballast.

Similar letters referto similar parts throughout the several views.

The tie has a bottom A, resting upon the ballast, and' sides B B, extending upward therefrom. The angles a ct are strengthened by a greater thickness of metal, said thickened portions extending from the angles a a inward on the bottom A a portion of the distance vtoward the center thereof and said thickened portions also extending from the angles a ot upward on the sides B B a portion of the distance toward the tops thereof. The sides B B are thickened or`ribbed at the tops C C for the purpose of affording a greater bearing-surface for the rails, said ribs C C, together with the thickened angles a a, increasing the strength of the tie at those points vwhere greatest strength is required and permitting the use of less thickness of steel in a portion of the bottom A and also in a portion of each of the sides B B. Each of the sides B B is further strengthened b vatransverse corrugation or corrugations d d under the rail, said corrugation or corrugations beginning at the tops of the sides B B and terminating in the thickened parts of the bottom of the tie.

c is a transverse corrugation, one or more of which is located between the rail and the end ofthe tie and extends across the bottom A and vertically across each of the sides B B to the top thereof. Z) is a transverse corrugation, one or more of which extends across the bottom A of the tie inside the rail, the purposes of said corrugations being to stiffen the sides and the bottom of the tie and to aid in preventing the tie from slipping longitudinally on the road-bed.

D is a steel fastening which secures the rail B to the tie, the top of said fastening D being Hush with the tops of the sides B B, the

shape ofthe fastening D being such that it conforms to and rests upon the bottom A of the tie the enti-re width thereof, thereby serv- ;ing as a brace to the sides B B and also as an aid in supporting the weight.

The fastening D has a lug e at each end, beut-at such an angle that when the fastening is placed in proper position in the tie the lugs e e and ends of the fastening D rest against the sides B B, to which the lug e e are firmly secured by the bolts H H, passing through the holes ffin the lugs e e, through the sides B B, and through the washers G G, which are held firmly against the sides B B by the taps g g for the purpose of bracing the sides. The heads h h of the bolts H H are shaped to conform to the angles of the fastening D, thus preventing the bolts from turning and also strengthening the angles of the fastening'D. 'lhelugs e e are cut out to form hooks for the purpose of engaging the rail;

E is a transverse thickened portion of-the fastening D, at the middle thereof, for the purpose of strengthening the same.

I I are openings in the bottom of the tie, showing where the steel has been punched and 'bent downward to form the corrugated ICO lugs K K. The purpose of the lugs K K is to aid in preventing the tie from slipping longitudinally on the road-bed.

Having thus described our invention, what we claim isl. In a steel railway-tie, the combination of a base A; sides B B extending upward therefrom; the tie being thickened at the angles a a; with the sides B B thickened or ribbed at the top C C toform a greater bearing-surface for the rails; said thickened portions and the ribs extending the entire length of the tie, substantially as specified.

2. In a steel railway-tie, the combination of a b ase A; sides B B extending perpendicularly upward therefrom; the tie being thickened at the angles a a, with a transverse oorrugation, or corrugations Vd d, in each of the sides B B under the rail, for the purpose of stilfening the sides B B of the tie, substantially as described.

3. In a steel railway-tie, the combination of a base A; sides B B extending upward therefrom; thickened at the angles a ct; the sides B B being thickened or ribbed at the tops C C; transverse corrugations d d in the sides B B under the rail; with a transverse corrugation c, or corrugations, between the rail and the end of the tie; and a transverse corrngation b, or corrugations, inside the rail, substantially as described, and for the purpose specified.

4. In a steel railway-tie, the combination of a base A; sides B B extending upward therefrom; thickened at the angles a a; the sides B B being thickened or ribbed at the tops C C; transverse corrugations d d in the sides B B under the rail; a transverse corrugation o, or corrugations, between the rail and the end of the tie; atransverse corrugation b, or corrugations, inside the rail; with lugs K K projecting downward from the bottom A of the tie, substantially as described, and for the purpose specified.

5. In a steel railway-tie, the combination of a base A; sides B B extending perpendicularly upward therefrom; the tie being thickened at the angles a a; a transverse corrugation, or corrugations d d, in each of the sides B B under the rail; lugs K K projecting downward from the bottom A of the tie, with a steel fastening D having lugs e e cut out to form hooks for the purpose of engaging the rail, substantially as shown.

(i. In a steel railway-tie, the combination of a base A; sides B B extending perpendicularly upward therefrom; the tie being thickened at the angles a a, with a steel fastening D having lugs e e cut out to form lhooks for engaging the rail, said fastening being placed under the rail, diagonally across the tie, and being secured to the sides B B of the tie by means of the bolts H H, passing through the holesffin the lugs e e and through holes in the sides B B of the tie, the said fasteningD thereby securing the rail to the tie, bracing the sides B B of the tie, and aiding in supporting the weight, substantially as shown and specied.

7. In a steel railway-tie, the combination of a base A; sides B B extending upward therefrom; thickened at the angles a a; the sides B B being thickened or ribbed at the tops C C; transverse corrugations CZ d in the sides under the rail; 4a transverse corrugation c, or corrngations, .between the rail and the end of the tie; a transverse corrugation b, or corrugations, inside the rail; lugs K K projecting downward from the bottom A of the tie; with a steel fastening D having lugs e e cut out to form hooks for engaging the rail; means for securing said fastening D firmly to the sides of the tie; said fastening D being placed underneath the rail, and extending from the rail to the bottom A of the tie, all substantially as shown and described, and for the purposes specified.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
