Application Med September 5, 1 912. Serial No. 718,731.

To all whom it may concern:

Beit known that I, LAFE OWEN, a citizen of the United States, residing at Lawton, in the county of Comanche and State of Oklahoma, have invented certain new'and useful Improvements in RailTies and Fasteners, ofwhich the following is a specification, reference being had to the accompanying drawings.

This invention relates to rail ties and fasteners and has for its primary object to produce a hollow rail supportingtie constructed of plastic material, and improved reinforcing or strengthening means arranged within the hollow of the tie.

Another and more specific object of the invention resides in the provision of a hollow tie, a series of longitudinal reinforcing rods and a plurality of tie rods connecting the same, a tie plate arranged upon the tie and having its ends extended downwardly over the ends of the tie, one of the reinforc.

ing rods projecting beyond the ends of the tie and coperating with the tie plate to lock the same upon the tie.

A further object of the invention resides in the provision of a rail fastener ofimproved form whereby the rails may be easily,"

quickly, and securely fastened upon the tie.

Still another object of the invention is to provide a device of the above character which is simple in construction, extremely strong and durable in use and may be manufactured at comparatively small. cost.

With the above and other objects in view as will become apparent as the description proceeds, the invention consists in certain constructions, combinations and arranger ments of the parts that I shall hereinafter fully describe and claim.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in whichv Figure 1 is a side elevation of a rail supporting tie and fastener embodying the present invention; Fig. 2 is a section .taken on the line 2-2 of Fig. l; Fig. 3 is an enlarged longitudinal 'section of one end of the tie; Fig. 4iso. 4perspective view showing one of the fastening members in osition upon the rail; Fig. 5 1s an enlargedp end elevation of the tie reinforcement; and Fig. 6 is a top plan view thereof.

Referring in detail to the drawin s 5 designates the tie which is constructe of concrete or other plastic material and is hollow or of inverted U-shaped form in cross section as clearly shown in Fig. 2. This plastic tie is strengthened by means of the reinforcement shown in detail in Figs. 5 and 6. This reinforcement consists of a plurality of parallel longitudinal rods 6. Tie rods 7 connect these longitudinal rods,` said tie rods being each provided with spaced eyes 8. These eyes are of uniform size and are arv ranged in the form of a semi-circle. The rods 6 are disposed through the corresponding eyes in the series of tie rods and the central one of these rods 6 is somewhat longer than the remaining rods (3 so that the same projects at its ends beyond the ends of the tie as clearly shown in Fig. 3. The extremities of this longer rod are beveled or inclined downwardly and outwardly as indicated at 9 for a purpose which will be clearly seen from the following description. The semi-circular arrangement of the longitudinal bars G and the eyes 8 in which they are supported produces a maximum of strength in the tie, the pressure upon the longitudinal rods being directed toward the center of the hollow tie. This reinforcement is of course embedded in the plastic material when the same is molded to form the tie in the usual manner.

My` improved fastening means for the rails which is designed to be employed in conjunction with the tie constructed as above described, embodies the tie plate 10 which extends longitudinally upon the upper surface of the tie and has its ends anguarly bent to yextend downwardly 'over the ends of the tie as indicated at 11. These downwardly extending ends of the tie plate are provided with rectangular openings 1Q to receive the ends of the central reinforcing rod 6 which projects beyond the ends of the tie. In lacing the tie plate in position on the tie, t e extremities of said plate engage the beveled or inclined surface 9 on the ends of the rod 6 and ride over the same. When the tie plate is forced into engagement upon the upper surface of the tie, the ends of the rod 6 will be received in the openings l2, thereby locking said late in position.

Upon each end of t e tie plate 10 and on the upper surface of the same, a chair plate 13 is welded or secured in any other preferred manner. This chair plate is of slightly Greater width than the tie plate l0 so that tie same overlaps the longitudinal BEST AVAILABLE CCP" my improved rail fasteners are arranged.

Each of these fasteners consists of a steel.

plate of the ret uired thickness which is bent intermediate o its ends to provide a semicylindrical rib or .,corrugation 14 which serves tostrengthen said plate and provide a housing for the inner end of a fastening bolt which will be later referred to. The fastener' plate isi-extended laterally from each side of the rib 14 as indicated at 15, and -from'said lattery portions lof the plate the saaie is flanged downwardly as at 16, the edges of said flan es being bent inwardly as at 17 beneai the longitudinal edges of the chair plate 13. The opposed walls of the'semi-tubular rib 14 are connected at one of their ends by a. plate 22 which is provided with a central opening to receive the longitudinally extending portion of a bolt 19. r1`he lower edge of the plate 22 engages the end of the chair plate 13. 'lhe inner end of this bolt is disposed at an angle of substantially forty-tive degrees as shown at 20 and extends through an opening which is drilled through the chair plate 13, said bolt being fixed in the openin in any preferred manner. The outer en of the bolt 19 is provided with' screw threads for the accommodation of a clamping nut 21. Upon the inner ends of the ortions 15 of the fastener plate, the upwart ly extending inclined clamping lugs 23 are formed. As clearly shown in Fig. 4 ofthe drawings, these clamping lugs are adapted to engage upon the base llan re of the rail R, which is seated upon the cliair plate 13. The lugs are moved into clamping engagementi withthe rail by adjustin the nut 21 upon the end of the bolt l0, ticreb forcing thc fastener inwardly upon tho o iair plate, the inwardly turned ends 17 thereof moving freely beneiitli the edges of the chair. By means of this construction it will be readily seen that. the rails may he easily and quickly as well as securely, clampet in position upon my improved tie so that spreading of the rails will he etfectually prevented. As the rail clamping plates are adapted to be stamped from a single'sheet of steel, it will be obvious that the same can be produced at small cost.

My improved rail tie andv fastener provides a supporting and retaining means'for the rails which is extremely strong, durable and lasting in practical use.

It will of course be obvious that the vari- .ends fixed in the tie plate an ousp'arts em loyed are susce t-ible of considerable mo ification in the form and prop'ortion'without departing from the essential features or sacrificing any of the advantaOes of the invention.

y IIaving thus described the invention, what is claimed is:

1. In a rail'faste'ner the combination with a tie late and a chair plate on each end of said tie plate, fastening members longitudinally movable upon the chair plates, bolts fixed at one of their ends in the tie plate and extending above the chair plate in spaced relation thereto, and nuts threaded upon said bolts to engage said fastening inembers and move the same upon the chair plate into engagement with the rail.

2. In a rail fastener, the combination with the tie plate and a chair plate secured thereon and of greater width than the tie plate, a pair of rail fastenintr members having-flanges extending beneath the longitudina edges of the chair plate, said fastening members being )rovided with tongues for engagement with the base of a rail, and means for moving the fastening members longitudinally upon the chair to clamp the tongues on t-lie rail base.

2l. In a rail fastener, the combination with a tie late and a chair plate secured thereon and of greater width than the tie plate, of a pair of fastening plates each provided with a senii-tubular strengthening rib formed centrally therein, the ends of the plates being downwardl flanged and extended inwardly beneati the longitudinal edges of the chair plate for sliding movement thereon, bolts having an ular inner extendingr above the chair late, said bolts being longirtudinally extent ed upon opposite sides ot' the rail above the chair plate., a plato conliiecting the opposite walls of the semi-tubular rib at one of its ends and provided with an opening to receive. one of the rods, spaced clanipin lugs inclined u iwardly from the 4,inner e ge of the fasteninfr plate for engagement with the rail iase, and nuts threaded upon the bolts to move the fasten ing plate-i inwardly upon the chair and enffage said lugs wit-h the rail.

In testimony whereof I hereunto atlix my signature in t-lie presence of two witnesses.
