Specification of Letters Patent.

Patented Oct. 18, 1910.

Application led December 26, 1908. Serial No. 469,429.

To all whom it may concern:

Be it knownV that I, THOMAS E. MCCOR- Miox, a citizen of the United States, and resident of Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Railroadj Ties, of Awhich the following is a specificathan the rail-carrying portion and that the plan view of the same.

bearing portion shall carry its greatest width between the rails and taper to the outer end of the tie.

It also comprehends the location of a recess in the end of the tie whereby the elastic rail-bearing member may be embedded in the frame and a recess for the adj ustment of the means that hold the elastic railbearin'g member and the rail clip.

Heretofore in hollow metallic railroad ties it has been the custom to manufacture the same in hollow pipe form of somewhat square shape in cross section and in some instances to place metallic reinforcing within the same or to fill the same with cement and in railroad ties formed from a casting there has been noidea of hollow pipe casting but what might be termed a simple frame casting. Both vof these forms of tie had distinct advantages yet neither of them could be termed a practical railroad tie and realizing the faults of both of these constructions I have devised a tie which in my opinion obviates all these dithculties at the same time producing from a casting a hollow frame tie that is of sufficient bulk to maintain its position and to so construct it that it cannot be dislodged without great diiiculty when it is once placed in position.

To explain my idea Figure l represents a drawing of the side view of the railroad tie embodying my invention, showing part of the same in section. Fig. 2 represents a Fig. 3 is a vertical section on the line 3-3 Fig. 1.

From an inspection of the drawing, more particularly illustrated in the section disclosed in Fig. 3, it will be observed that the central part of the tie between the rails is cast hollow and that lateral ribs project not only on the outside but on the inside and that the walls of the casting project below the level of the casting itself, forming ribs along the bottom thereof and for the purpose of reinforcing the upper portion of the casting I have arranged one cross brace having lateral ribs projecting therefrom in the same manner as the body of the casting. I have done this principally to save weight. It will also be observed that the construction just described refers to the central portion of the casting or the portion between the rails and which for convenience I desire to term the supporting portion.

The tie is constructed in this manner so that when the same becomes embedded in the earth the central portion acts as a wedge in the earth to form a solid foundation for and to resist any strain brought upon the rails by the passing of the train.

To more fully describe the details of my invention, the tie may be divided into two parts, the central portion between the rails and the rail-carrying portion. The central portion between the rails is cast hollow, the side walls a and b thereof projecting below the body of the casting and forming the vertical projections for preventing the tie from moving when once embedded in the earth. These side walls are also provided exteriorly and interiorly with lateral flanges a a2, Z1 b2, the function of which is the same as the lower projection of the side walls. A vertical brace c is provided, extending along the upper portion of the ties, which latter also carries lateral flanges c c2. From an inspection of a sectional view of this construction it will be perceived that when the tie is embedded in the earth, the space on the interior and exterior will be illed with earth,

j practically making it impossible to move the tie when once set in position; and to further provide that the earth may thoroughly fill the interior of the tie, I have provided slots a3 and 3 in the side walls. It is my intention to construct these flanges with the exception of the top brace, so that they shall be widest or project farthest between the rails and gradually taper them to the outside end of the tie.

The end portions d of the tie are preferably cast with two recesses e and it, the recess e being parallel with the direction of the rail and so arranged that an elastic substance e', such as wood, may be inserted therein for carrying the rail; and the other recess, h, being at right angles thereto and so arranged that the bolt g of the rail-securing means f f shall project therein so that a nut attached thereto may be adjusted to hold the rail in position.

It will be observed from an inspection of F ig. l, that the hollow central portion and the rail-carrying portion are separated by a dam or brace cl cl2, the upper portion al being inclined from bottom to top to form a brace for the lateral flanges c c2 of the vertical brace c and also to save weight in the casting.

I have tapered the tie from the bottom to the top and also from a suitable point between the rails to the end of the tie, and I have provided the vertical brace c in the center of the tie so that should it be desirable to embed the tie in cement for the purpose of street railroads a very small portion of the same would appear above the surface and in this utilization of my tie it would be my intention to countersink the rail so that the top of the same would practically coincide with the upper surface of the tie and also to provide an arm hole at the end of each tie so that access can be had to the rail-securing means within the recess below the rail.

It will be apparent from an inspection of the drawing that when a tie manufactured in accordance with my invention is placed in the earth and the earth suitably tamped or packed around and within it, the lateral anges and the vertical flange at the bottom together with the resistance afforded by the vertical top brace with it-s lateral flanges render the tie absolutely immovable and that by a removal of a slight amount of earth at the ends of the tie, the elastic rail-bearing means may be removed and renewed and the life of the tie only limited by the capability lset in said groove.

2. A railroad tie having, in combination,

a central slotted portion composed of a plurality of separated bars having laterally eX- tending flanges, and a top portion provided 'with a transverse groove in each end, and

rail-bearing material of a substance differ ent from the tie secured in said groove.

3. A railroad tie comprising a central slotted body the'sides of which converge toward its top, and the bars of which are flanged to provide anchoring portions and a rail-bearing portion at each end of the slotted portion provided with a transverse groove, and an elastic rail-bearing material secured in said groove.

4. A railroad tie having a central body portion and rail-bearing end portions, each of the latter being provided with a transverse groove in its surface, and a longitudinal chamber extending from the end thereof toward the anchoring portion and extending under said groove, a rail-bearing block set in said transverse groove with its surface flush with the surface of the central Y portion, and rail-fastening means carried by said block including bolts passing through the latter into said chamber. y

5. A railroad tie having, in combination, a central portion tapered from its bottom to its top and end portions each tapered on its opposite sides and on its bottom from the central portion to its end, and a railbearing block carried by said end portion having its surface Hush with the surface of the central portion.
