Specification of Letters Patent.

Patented Sept. 11, 191?.

Application filed. May 10, 1917. Serial No. 167,752.

To all whom it may concern:

Be it known that I, EDWIN T. l/VADE, a citizen of the United States, residing at Jackson, in the county of Hinds and State of Mississippi, have invented a new and useful Rail Tie and Fastener, of which the following is a specification. l

The present invention relates to ra1l ties and fasteners, and is particularly an improvement over the rail tie and fastener disclosed in my copending application Serial No. 110,972, filed January 6, 1917.

It is the object of the invention to provide a flexible concrete cross tie of the general construction disclosed in said application, and possessing improved features of construction, to enhance the utility and eflicienc'y thereof.

With the foregoing and other objects in view which will appear as the descrlptlon proceeds, the invention resides in the com-l bination and arrangement of parts, and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein:

Figure 1 is a perspective view of the tie with the rails and corresponding elements removed.

Fig. 2 is a plan view of the tie, one sleeper being broken away in order that the View can be made on as large a scale as possible.

Fig. 3 is a sectional detail taken on the line 33 of Fig. 2.

Fig. 4 is a sectional detail showing one of the bar holding bolts.

The tie embodies a pair of alining sleepers 1 of concrete or equivalent material having their adj acent'ends spaced apart slightly, and said sleepers have embedded therein reinforcing rods or bars 2. The sleepers are provided underneath those portions on which the rails R seat, with depending thickened portions 3, and the sleepers are further provided with parallel longitudinal grooves 4 extending from their adjacent ends to point-s above and slightly beyond the thickened portions or enlargements 3. Bars 5 are seated inthe grooves 4 flush with the upper surface of the sleepers, and serve as a flexible connection between the sleepers, whereby they can spring relatively to one another. The terminals of the bars 5 extend downwardly, as at 6, through the sleepers adjacent to the enlargement 3 at those sides thereof farthest apart, and nuts 7 are threaded onto the terminals (3 and bear upwardly against the sleepers to fasten the terminals of the bars rigidly ther to. As a means for securing the bar 5 to the sleepers near the adjacent ends thereof, bolts 8 are engaged downwardly to the sleepers and have hooks 9 at their upper endsengaging over the bars, while nuts 10 are threaded upon the lower ends of the bolts 8 for drawing them tightly into place. The adjacent ends of the sleepers 1 are beveled, as at 11, to facilitat the flexing of the bars 5 between the sleepers.

In order to assist in supporting the rails and to fasten them upon the tie, a longitudinal elongated tie plate 12 is embedded in each sleeper between the bars above the enlargement 3, and is provided at its ends with upstanding transverse lugs 13 provided with the undercut grooves 1 1, the upper walls of which are beveled. The plates 12 are flush with the upper surface of the sleepers, whereby the rails R in extending across the tie seat snugly upon the bars 5 and plates 12, as well as the surfaces of the sleepers themselves. The rails seat upon th plates 12 between the ends and lugs 13 thereof, and a pair of bolts 15 is extended downwardly through each plate 12 and sleeper and their lower ends threadedly engage tapered nuts 16 embedded within the lower portion of the enlargement 3. Said nuts can be readily removed should the bolts break, for purpose of replacing the parts. The heads of the bolts 15 are uppermost and overlap the edges of the base flanges of the rails, whereby to secure them upon the plates 12 when the bolts are tightened.

To complete the fastening of the rails, keys 18 of inverted T-shaped cross section are driven between the lugs 13 and bolts 15 and their flanges are beveled, as at 19, to engage under the heads 17 of the bolts and the overhanging portions of the lugs 13, with a wedge fit, thus holding the belts in engagement with the rails, and effectively retaining the rails in place upon the tie.

Having thus described the invention, what is claimed as new is 1. A. railroad tie embodying a sleeper,

bars seating thereon and having-terminals extending downwardly therethrough,-means engaging said terminals for holding the bars in place, and means carried by the sleeper between said bars for securing a rail thereon.

2. A railroad tie embodying a sleeper, having an enlargement bars embedded within the upper portion of the sleeper and hav ing terminals extending downwardly therethrough at one side of said enlargement, means engaging said terminals for holding them in place, and means engaging said enlargement and disposed between said bars for holding a rail thereon.

3. A railroad tie embodying a sleeper, bars embedded in the upper surface thereof, a plate embedded in the upper surface of the sleeper between said bars for the seating holdinga railon said plate-and-bars, and nuts embedded in the lower portion of the sleeper for the engagement of the bolts.

5. A railroad tie embodying a sleeper, a tie plate thereon having upstanding lugs, bolts extending downwardly through said plate and having their heads uppermost to overlapthe base flange of a rail, and keys adapted to be driven between said lugs and heads of the bolts.

6. A railroad tie embodying a sleeper, a tie plate thereon having; upstanding lugs provided with undercut grooves, bolts extending downwardly through "said plateand having their heads uppermost to overlap the base flange of a rail seating on said plate between the' lugs, nuts embeddedin thesleeper for the engagement of the bolts, and keys of inverted T-shaped section adapted 'tol'be driven between said lugs and heads to 'en:

gage under them.

In testimony that I claim the foregoing as my own,'I have hereto affixed my signature in the presence of two witnesses.
