Specification of Letters Patent.

Patented Dec. 25, 1905.

Application filed April 27, 1906. Serial No. 314,072.

To all whom it may concern:

Be it known that 1, JOHN M. COLLINS, a citizen of the United States, residing at South Pittsburg, in the county of Marion and State of Tennessee, have invented certain new and useful Improvements in Railroad Constructions, of which the following is a specificatron.

This invention embodies improvements in the construction of railro'ads,and relates to that type of inventions in which a hollow metallic tie is utilized, together with peculiar means for securing the rails to the tie, a filler of concrete, asphalt, cement, or similar plastic material being used to fill the hollow bodies of the metallic ties.

The essential feature of the invention resides in the peculiar construction of the detail parts included therein and other features the advantages of which will appear more fully hereinafter.

The invention also includes a construction of attaching means between rails and ties wherein the metallic tie is dispensed with and the wooden tie is used in connection with parts hereinbefore mentioned.

For a full understanding of the invention and the merits thereof and also to acquire a knowledgd of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings, in Which.

Figure 1 is a transverse sectional view through a road-bed, ties being shown constructed in accordance with the invention, as

well as the means for securing the rails thereto. Fig. 2 is a section taken on the line X X of Fig. 1. Fig. 3 is a detail perspective view of one of the angle-bars used to secure the rails to the tie. Fig. 4 is a vertical section showing the adaptation of the invention when Wooden ties are used in construction of the road-bed. Fig. 5 is a detail view of one of the angle-bars employed at a joint between two rails, the said bar being formed with square bolt-receiving openings.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

In the drawings the numeral 1 designates a hollow metallic tie, preferably made of heavy sheet or cast metal and formed with a longitudinal slot 2 in its bottom portion. The ties when of hollow form are preferably of somewhat rectangular contour in crossshown most clearly in Fig. 2. Adjacent to each end of each tie are spaced vertical 0 enings 3, formed in the top portions thereo so as to rece ve hooks 4, rojecting from the lower portions of anglears 5, provided to support the rails 6 at opposite sides, said angle-bars being connected by the usual bolts or fastenings 7 andbeing prevented from displacement from thetie by the interlocking connection established between the hooks thereof, which project downwardly therefrom and beneath the top of the tie To subserve the rigidity of the ties and the perfect ballast of the road-bed, it is, contemplated that the said ties when in position shall be filled with a filler 8, of cement, asphalt, or concrete, which is placed in the ties when in plastic state and permitted to harden in an obvious manner. The filler 8 also cooperates to prevent looseness or play of the means whereby the angle-bars 5 are con nected with the ties and in this capacity are of reat advantage.

n the modification shown in Fig. 4 the wooden tie 9 is utilized and is provided adj acent to its ends with s aced recesses or seats 10, into which the hoo s 40f the angle-bars 5 are received. in this construction a bedplate 11 is securely attached by spikes or similar fastenings to the upper side of the tie 9, near an end thereof, and this bed-plate is formed with openings 12, just above the recesses 10, so that the hooks 4 of the anglebars may project through such openin s 12 and enter the recesses 10 when the interlockin connection of the angle-bars is establis ed.

At intermediate points along the rails the angle-bars are comparatively short and are preferably each provided with two bolt-openings, as indicated in Fig. 3, while at the joints between the rails longer angle-bars 5 are em-- ployed which are provided with four boltopenings, two for each rail, as shown in Fig. 5. Attention is also directed to the fact that the bolt-receiving openings in the angle-bars 5 on the inside of the track have a square or angular formation and engage in the usualmannerwith the heads of the bolts to prevent them from turning while the nuts are being placed in position.

It will be noted that in the construction shown in Figs. 1 and 2 the cement filling the hollow metallic tie constitutes a ballastingbody, the top of the metallic tie comprising a beliesting hooiy plate se fired the heHesting-bofly in e -"Ii dent mama .piate eppiieti to the beHesting-body and formaiwithepaeed openings, rails having the base poi'tloes thereof restingon the top plate, angle-hers at opposite sides of the mails and heving hooks projeeting from the lower portions thereof .andpessing 7. through the "openings of the-top pieteseno eountersur *1 in the beiiasting-body of the tie, said hooks engaging-beneath the top piste to prevent displacement of the rails therefrom, and; fats temngs passing through the eng1ebars-en the rails and connecting said angle-bars in the manner specified.
