To all whom it may 0071662177..

Be it known that I, Jornv l Tonon. a citizen of the United States, residing at ll ilmington, in the county of Clinton and State of Ohio have invented certain new and useful Improvements in. Railroad-li ies; and I do hereby declare the following; to be a full clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make anduse the same.

This invention relates to new and useful improvements in railway tiesand has for its principal object the provision of a tie which will prevent the rail from spreading. Slllli'illg or creeping.

Another object of the invention is the provision of a tie in which the resilient qualities of the old type f wood tie are retained and combined with the advantages which are present in the use of a metallic tie.

A further object of the invention is to provide a simple and effective means for securing the rail in place on the tie and preventing the same from becoming displaced.

Still another object of the invention to provide a concrete tie in which the material will be C'OllSldQlElbiy reinforced and thereby the strength of the tie will he materially increased.

With the above and other objects in view, the invention consists in the novel combination and arangement of parts which will be fully set forth in the follmvinospecification and accompanying; drawings, in which Figure 1 is a view of a tie constructed in accordance with this invention showing the same partly in section to more clearly'illustrate the reinforcement bars, Fig. 2 is a top plan view of a tie constructed in accordance with this invention, and Fig. 3 is a transverse sectional view taken on line 33 of Fig. 1. Fig. 4 is an enlarged detail, longitudinal, sectional view of a. fragment of the tie to more clearly illustrate the nut lock and rail clamp.

Referring now to the drawings by charac ters of reference, the numeral 1 designates as an entirety, a railroad tie constructed in accordance with this invention which comprises the plastic body portion 2 which is formed of concrete or a similar material.

This body portion 2 is provided near each end with a recess 3 in which. the wood hearing; block 4, forming a rail seat, is adapted to rest. \w plurality of longitudinally extending, reinforcing bars 5 are. embedded in the plastic material and extend parallel with the bottom of the tie. A plurality of long: bowed steel rods 0 are also embedded in the concrete. and extend substantially throughout the entire length of the tie. These rods 6 are bowed upwardly at their center, and are arranged to receive any verti al strain to which the tie might be sub iected. A plurality of bowed reinforcing elements 7 which are of less length than the reinforcing! members G. are also provided and are adapted to cooperate 'avith the be foreanentioned reinforcing bars in taking up the lateral strain against the tie. These bars '7 are bowed as illustrated in Fig. l and are of substantially half he entire length of the tie, thus addingconsiderably to the strength of the tie at its center and preventing" the same from cracking or becoming injured in any way. Near ear-h end of the tie-is provided a pair of transverse apm'tures S which extend vertically throughoutthe entire depth of the tie and are adapted to receive the bolts 9 by means of which the rail-securing elements 10 are held in place.

Formed integral with each of the railsecuring elements 10 near the end opposite the flange engaging member is preferably provided the upstanding car 11 having; formed therein the aperture 12 through which the cotter pin 13 is adapted to extend. A. suitable body portion 14 having" formed thereon the cars 15 is provided, and each of the cars is provided with apertures through which the pin 13 is adapted to extend, and thus pinotally secure the bodv portion to the car 11. The end of the beds portion opposite the pivoted end is provided with the hexagonal aperture 16 which is arranged to receive the nut which cooperates with the bolt and prevents thesame from becoming loosened.

It will be apparent from the foregoing that owing to the particular arrangement and construction of the reinforcing elements. the tie will be prevented from becoming cracked or broken since the strain is taken up by the bars 5, 6, and 7. It Will also be apparent that the rails will be prevented Elli from sinking since these bars are arranged to exert upward pressure against" the rail, thus holding the same at the proper gage and preventing any depression and similar undesirable results which might come from the tie cracking in the center and permitting the rails to drop.

Owing to the position and arrangement of the blocks 4, it will be apparent that any should said blocks become worn, they may be removed withoutin any way necessitatinv the'lo'osening of the rail clamp. Thus it w ll be seen that a material saving in labor will be made in the use of a tie of this construction.

Vvhile in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that such changes may be made in the combination and arrangement of parts as i will fall within the spirit and scope of the shortbowed reinforcing elements embedded in the plastic body portion, both the long and the short reinforcing elements being arranged so that their greater length is above road. shocks will be absorbed thereby, and

the first-mentioned reinforcing elementsto add strength to the center of the tie, means carried by the tie near each end to secure a railroad rail in place.

2. In a device 01": the character described, aplastic body portion, a plurality of rein forcing elements embedded in the bodyportion and extending substantially throughout its entire length, said reinforcing elements being parallel with the longitudinal walls of the body portion, a plurality of relatively short bowed reinforcing elements superposed and embedded in the plastic body portion above the first-mentioned reinforcing elements, the ends of the secondmentioned reinforcing elements terminating substantially beneath the inner edges of the point where the rail flanges rest, and a plurality of relatively long reinforcing. elements, said long reinforcing elements being bowed at their center, and the central portions thereof superposed above the short bowed reinforcing elements, thereby strengthening the center of the tie and prev'entingthe ends from sinking, and means .to hold railroad rails firmly-in place on the tie.

I In testimon whereof I aflixmysignature in presence 0 two witnesses,

JOHN F. TUDOR.
