To all whom t may concern.'

Be it known that I, FRANKLIN A. WIL- soN, a citizen of the United States, and a resident of Hagerman, in the county of Gooding and State of Idaho, have invented certain new and useful Improvements in Reinforced-Concrete Railway-Ties, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in reinforced concrete railway ties and rail fastenings.

One object ofthe invention is to provide a concrete railway tie having an improved 'construction and arrangement of reinforcing rods and bars, whereby the tie is strengthened and elfectually braced.

Another object is to provide a railway tie of this character having an improved construction and arrangement of adjustable rail fastening devices whereby the sections of the rails are firmly secured to the ties,

Y and whereby any of the rail sections may be readily removed when desired. Y

YV ith these and other objects in view, the present invention consists in the combination and arrangement of parts as will `be hereinafter more fully described and finally pointed out in the appended claim, it being further understood that changes in the specific structure shown and described may be made within the scope of the claim, without departing from the spirit of the invention.'

In the accompanying drawings forming a part of this specification, and in which like numerals of reference indicate similar parts in the several views: Figure 1 is a central, vertical longitudinal section of my improved railway tie and rail fastening devices. Fig. 2 is a plan view of the same. Fig. 3 is a side View of the reinforcing and bracing rods of the tie. Fig. 4f is a cross sectional view thereof taken on the line 4t, 4 of Fig. 3. Fig. 5 is a side view of one of the adjustable rail fastening members.

Referring more particularly to the drawings, 1 denotes my improved concrete tie, which is reinforced by the upper parallel longitudinal reinforcing rods 2, and lower parallel longitudinal reinforcing rods 3, said rods extending nearly the full length of the tie and are arranged therein near the four longitudinal edges of the same. The upper and lower rods 2 and 3 of each side of the tie are connected together at their Specification of Letters Patent.

ends by vertical end bars et, through which the ends of the rods are passed and clenched by bending said ends as shown. The bars 1l at each end of the tie are connected to gether by pairs of diagonally arranged, crossed rods 5, the ends of which are also passed through the bars and bent. ln addition to the rods 2 and 3 the tie is further reinforced and braced by two combined reinforcing and bracing rods 6, which are arranged between the upper and lower rods 2 and 3 at each side of the tie and have their ends secured in the bars 4 near the lower ends of the same. The rods 6 are arched or bent upwardly midway between their ends,V

and are engaged at their upper central portions with truss bars 7 secured between the rods 2 and 3 which are passed through said bars near their ends as shown.

The rods G are secured to the bars by passing the rods through the bars as shown with their ends secured near the lower parts of said end rods. The rods 6 and bars 7 when thus arranged form truss braces, which effectually strengthen and brace the ties and enable the same to resist the great strain to which they are subjected by the passage of trains over the same.

In connection with my improved ties, l provide rail supporting and fastening devices, comprising a longitudinally disposed rail supporting plate 8, which may be of any suitable width and which is embedded in the upper side of the tie so that the upper surface of the plate is Hush with the upper surface of the tie. The plate 8 is arranged centrally in the upper side of the tie and extends approximately throughout the length of the same.

The plate 8 near each end thereof and on each side of the point crossed by the rails is serrated as shown at 9 and in the serrated parts of the plate are slots 10, which register with vertical slots 11, extending transversely through the tie. The slots 11 comi municate or register at their lower ends with slots 12, in bolt holding plates 13, set into the bottom of the tie near each end thereof as shown.

Engaged with the the plate 8 are rail having serrated lower sides which engage the serrated surfaces 9 of the plate and which have formed thereon rail engaging lugs l5, which engage the flanges of the rail as shown. The blocks 14 are securely fasserrated surfaces 9 of clamping blocks 14,

Yso

tened in position on the plate 8 with the lugs 15 thereof, in operative engagement with the flanges of the rails by clamping bolts 16, which are engaged with the slots in the plates S and 13 and in the ends of the tie. The upper ends ofthe rods are provided with the clamping nuts 17, and on the lower ends thereof are clamping nuts 1S. The nuts when screwed up against the plates 13 and the blocks 14 draw the serrated surfaces of the blocks down into rigid en? gagement with the serrated surfaces of the plate S and lugs 15 into firm engagement with the flanges of the rails, thereby securely clamping the latter to the tie. The engagement of the serrated surfaces of the blocks 14 with the serrated surfaces 9 of the plate, positively prevents the blocks from slipping laterally in either direct-ion, said blocks thus holding the rails againstJ spreading or tilting, as well as securely clamping the same to the ties. The slots in the plates 8 and 13 and ends of the tie permit the rails to be adjusted theproper gage, and also permit the blocks to be slipped back when the nuts on the bolts 1G are loosened and thus disengaged from the rails thereby releasing and permitting the removal of the latter.

From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Having thus described my said invention, what claim as new and desire to secure by United States Letters Patent is:

A railroad tie of the class described, comprising a plastic body and a metal frame embedded therein including two upper parallel longitudinal reinforcing rods, two lower parallel reinforcing rods, said rods located near the four longitudinal edges of said body, two vertical end bars connected to the ends of said upper and lower rods, diagonally arranged cross rods disposed in sets of two having their ends secured to the ends of said vertical ends bars, two centrally disposed vertical truss bars each being secured to an upper and lower reinforcing rod, and two bent bracing rods arranged between the said upper and lower reinforcing rods having their intermediate portions held within openings of said truss bars and their ends secured to the lower portions of said end bars, as in the manner setl forth.

In testimony whereof I afiix my signature, in presence of two witnesses.
