Application led December 29, 1916. Serial No. 139,487. j

-crete rail ties, by providing a tie of this fnature with a novel and effective reinforcement that will admit of the tie withstanding considerable weight without danger of the body of the tie becoming cracked, thereby increasing the life of the tie.

Another object of the invention is the provision of novel means for retaining the rails of the track on the tie.

` 1n w j Figure 1 is a longitudinal sectional view Other objects' will appear and be better understood from that embodiment of my invention'of which the following is a specication, reference being had to the accompanying drawings forming a part thereof, hich:

taken through the vtie constructed in accordance with my inventlon, and showing the manner of securing the companion rails of a track to the tie, the said rails being in section,

Fig.I 2 is a top plan view of the tie shown in Fig. 1, y

Fig. 3 1s an end view of a plurality of adjacent ties,

Fig. 4 is atransverse section taken through one of the ties,l

Fig. 5 is a perspective view of one of the rail-supporting plates detached from operative position,

Fig. 6 is a detail perspective view of one end of the reinforcing element for the tie,

Fig. 7 is a perspective view of one of the innermost rail clamping plates detached from operativ| 1 cition.

Referring to ne drawings inv detail, the rail tie is shown as' consisting of a body portion 1 formed of concrete. Embedded within the concrete body 1 of the tie is a reinforcing element 2 that consists of an elongated and flat plate, having its opposite 1ongitudinal edges bent laterally in opposite directions, as shown at 3, and thence bent upon themselves, in opposite directions land 1n parallelism with the laterally bent portions 3 to provide ianges 4 that project beyond the plate 2, as shown in Fig 6 of the drawings. By so bending the opposite longitudinal edges of the plate 2, a reinforcing element of I shape in cross section will be provided. The plate 2 is provided with a plurality of openings 5, that admit of the material, of which the body 1 of the tie is formed, entering therein .and securly anchoring the plate 2 in position and also admit of a greater compactness of the concrete. The 'flanges 4 are provided with inwardly extending tongues 6, which are embedded within the concrete and are formed by displacing portions of the flanges 4, and the openings defined by the displacement of the tongues 6 form pockets for the reception ofv .portions of the concrete forming the body 1 of the tie. The

anges

3 and 4 onthe plate 2 are reduced, adjacent their opposite ends, as shown at 8, for-a purpose to be hereinafter described.

A pair of rail-supporting plates 9 are mounted on the upper surface of the tie 1 and are located, respectively, adjacent the opposite ends of the tie, and are adapted to support the companion rails A of a track. Each of the plates 9 is of substantially rectangular shape and has its opposite ends provided with raised portions `10 and 11, the raised portion 11 being disposed innermost and has its inner longitudinal edge beveled, as shown at 12. Each plate 9 has associated therewith 'a pair of clamping plates designated, respectively, by the

numerals

13 and 14 and are located, respectively, on opposite-sides of the adjacent rail A. The plate 13 is located exteriorly of the adjacent rail A and has its outer edge abutting against the adjacent edge of the raised portion 10 on the plate 9, and the plate 14 abuts against the raised portion 11 on the inner end of the plate 9 and has that edge opposing the beveled face 12 beveled to agree with the beveled face 12, as shown more particularly in Fig. 2 of the drawings. The

plate 9 is provided adjacent the raised y ortion 11 with a corrugated surface 15, W ich is adapted to cooperate with a similar corrugated face formed on the lower or under side of the plate 14, so as to prevent lateral movement of the plate 14 when the latter is in operative position. The

plates

13 and 14 areprovided with flanges 16 which engage over the adjacent longitudinal .edges of the base liangc of the adjacent rail A.

A pair of transversely extending and spaced plates 17 are embedded in the body 1 of the tie, at each end thereof, and are 1ocated beneath the plate 2, and adjacent the lower side of the body of the tie 1, and underlie the respective reduced portions 8. The plates 17 of each pair are so spaced from each other that they underlie the upper adjacent

rail fastening plates

13 and 14. Each plate 17 of each pair is` provided with a pair of spaced openings through which ex-. tend a pair of bolts 18. All of the bolts 18 have their lower ends provided with heads that are disposed adjacent the lower side .of the tie 1 and embedded therein. The

bolts 18 ext-end through openings 19 formed in the plates 9 and through openings 188L formed in the respective rail-

fastening plates

13 and 14 and have their up er ends threaded for the reception of suita le lock nuts 20. The openings 18 in the innermost plates 14 that receive the upper ends of the bolts 18 are elon ated and extend in parallelism with the eveledfaces on the innermost raised portions`11 and the plates 14. By locating the lower or headed ends of the bolts 18 yadjacent the lower side -of the body of the tie 1, removal of the bolts *can be easily and conveniently effected, it

necessitating only the removal of the nuts '2O and then 4striking the upper end of the bolts118 with a suitable implement, such as a hammer, so as to force the bolts 18 downwardly and causing the heads or lower ends the concrete located bethat the headed ends of After the bolts "stituted therefor .and the openings made in 'the lower side of the tie by the displacement of thefmateral on the downward movement of the bolts, can be filled with concrete Lso as to conceal the lower ends of the bolts i f i is,

cesses formed by the reduced portions 8, so

y and also to .help support the bolts in position. Thebolts 18 extend through the rethat the bolts canlie in close proximity to f the plate 2.

The operation of vsecuring 'the rails in p0- sition on the tieis effected as follows: The

.rails `are rst positioned on theI plates 9,

approximately centrally thereof, andplates 13 are then disposed at the outer sides of the rails and secured to the plates 9 by the outermost pairs of bolts and

nuts

18 and 20, the

bolts can be subformedof concrete, an e ong'ate Lampesy 'the rails with the elongated openings therein receiving the upper ends of the innermost airs of bo ts 18, each of the plates 14 being eld by a suitable tool, not shown, in spacedv relation with the adjacent plate 9 so, as to hold the corrugated vlower surfacesof the plates 14 spaced above the adjacent corrugated surfaces 15 on the plates 9. Each plate 14 is then moved transversely ofv the adjacent plate 9, in either direction, resulting in theibeveled faces on the plate 14 andthe adjacent raised portion 11, and also the walls of the elongated slots inthe plate 14, effecting movement of the plate 14 either toward or away from the. adjacent' rail. When the plates 14 have been given the required amount of movement either toward or away from the rails, the said plates are lowered so as to eliect engagement between' the corrugated surfaces formed, respectively, on the lower sides of the plates -14 and the upper sides ofthe plates 9 so that the plates 14 will be held against lateral movement on f the plates 9. The nuts 2O on the innermost invention what its opposite longitudinal edges bent in op posite directions and then bent upon themselves 'in reverse directions, the said bent edges providing flanges, the said flanges being reduced in width adjacent the opposite ends of the plates, and tongues formed on the flanges and engaging in the-tie body.
