AUGUST BAGA, OF FAYETTEVILLE, TEXAS.

RAILROAD-TIE.

roeaoesl To all whom it may concern Be it known that 1, AUGUST BAoA, a citizen of the United States, residing at Fayetteville, in the county of Fayette and State of Texas, have invented new and useful Improvements in Railroad- Ties, of which the following is a specification.

The present invention relates to railroad ties, and, more particularly, to that class or type of ties which are constructed of concrete or the like and are furnished with in ternal reinforcements.

It proposes certain hereinafter-described improvements in the construction and arrangement of the reinforcing devices, Whereby such devices are enabled to act not only to strengthen the tie, but, also, to serve the function of chairs for the rails and of anchors for the rail fasteners, and, further, are rendered capable of being readily attached to and detached from the rails, so that either the latter or the tie may be easily repaired when injured.

An embodiment of the invention is illustrated in the accompanying drawing, whereof:

Figure 1 is a longitudinal vertical section of the tie complete; Fig. 2 is a transverse section on line 22 Fig. 1; and Fig. 3 is a perspective view of a detail.

The tie 5, as shown in said drawing, is in the form of an isoceles trapezoid in crosssection, and is constructed, preferably in situ, of concrete or other suitable cementitious composition, the width of its upper or top face being appreciably less than that of its base. It has embedded within it, during manufacture, the improved reinforcements about to be described. These reinforcements consist, generally, of a main device 6, here shown as a flat metal bar, and an auxiliary device 7, mounted upon each end thereof. The bar just referred to occupies a horizontal position approximately central of the tie and extends almost from end to end of the same, while the devices 7 serve both as anchors for the rail fasteners and as rail chairs. The latter devices are preferably formed by inverted U-shaped metal frames and are permanently fastened at the free ends of their side members or legs to the bar 6, being provided for that purpose with inbent terminals 8 through which the rivets 9 directly pass. The open central portions or interiors of these frames are completely filled with the cement or other substance,

and their height is such that, when in place in the tie, the outer faces of their top members are flush with the top face of the tie.

The aforementioned top members are each formed with a pair of openings '10 which are threaded and are designed to recelve the lower ends of a pair of bolts 11, the bolts also passing through openings 12 in a pair of rail clips 13. These clips are arranged upon opposite sides of the rails 14 and are formed at their inner ends with shoulders 15 that engage the rail flanges.

While the invention is to all intents complete as above described, it is considered advlsable to provide a means for protecting the upper or outer face of the tie, such means being here shown as consisting of a fiat wooden board or plate 16 having the same dimensions as the face specified. This cover plate is mounted directly upon the said tie face and is formed with openings 17 that register with the bolt openings 10, the rails extending across the plate, and the clips 13 mounted upon the latter and engaged with the flanges of said rails, in the manner depicted in Fig. 1.

In carrying out the invention, a trench is first dug in. the road-bed at the point where the tie is to be located and of the same shape and dimensions as the tie, and into this trench is'poured a quantity of the plastic cement or other compound sul'licient to about half fill the same. While the cement is still in a plastic condition, the bar 6 is placed in the trench upon top of the cement and in proper position for the rails to pass across the frames 7, which latter have previously been riveted to the bar in the manner above indicated. The remaining quantity of cement necessary to complete the tie is then poured into the trench, leaving the outer faces of the top members of the frames exposed and flush with the surface of the cement. The cover plate or board 16, if used, is next laid upon the cement, after the latter has set sufliciently for that purpose, and the bolts then passed through the openings 17 and 10 and engaged with the clips, which, in turn, are engaged with the rails in the usual manner. In this way, it will be seen that the frames 7 serve not only as chairs for the rails, by reason of their location directly beneath the same, but, also, as anchors for the fastening bolts and clips, owing to the engagement of the bolt ends in the threaded openings 10. Moreover, the filling of cement in the interiors of the frames firmly anchors the latter in position and prevents any movement thereof relative to either the bar or the rails, while the tie itself, by reason of its shape, is itself held in place in the ground. The ties can thus be constructed at the very point where they are to be used, and substituted for the ordinary wooden ties without necessitating their being hauled from one point to another, or interrupting traffic over the rails. Also, in the event of any sinking of the ties, or other injury thereto, or to either the cover plates or the rail fastenings, the said plates and fastenings may be readily removed from the ties and replaced by new ones, and fresh cementpoured into the trenches.

V I claim A railroad tie of cementitious material having embedded within it a reinforcement consisting of a longitudinally-arranged bar provided upon each end with an upstanding,

hollow, metal frame which is riveted directly thereto and has the outer face of its top member exposed and flush with the top face of the tie, said member being formed with a pair of threaded bolt holes; in combination with a cover plate mounted upon said tie face and formed adjacent each end with a pair of bolt holes registering with those of the adjacent frame, pairs of bolts passed through the second-named pairs of openings and engaged at their lower ends in the threaded, first-named pairs of openings,

and a pair of rail-engaging clips mounted upon said cover plate and engaged by said bolts. 7

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

AUGUST BAGA.
