METALLIC RAILROAD-TIE.

SPECIFICATION forming part of Letters Patent No. 773,114, dated October 25, 1904.

' Application filed March 24., 1904. Serial No. 199,813. (No model.) I

To all whom, it mayconccrn:

Be it known that I, HENRY HARDEN ASH- LOOK, a citizen of the United States, residing at Clyde, in the county of Cloud and State of Kansas, haveinvented a new and useful Metallic Railroad-Tie, of which the following. is a specification.

This invention relates to metallic railroadties; and it has for its object to provide a de vice of this class which shall possess superior advantages in point of simplicity, durability, and general efficiency.

With these and other ends in view, which will readily appear as the nature of' the invention becomes better understood, the same comprises a tie consisting of a single casting provided at the ends thereof with downwardextending earth-engaging flanges and provided upon its upper side with parallel elevated rail seats, the latter being tapped through for the reception of rail-securing bolts which are speciallydesigned to cooperate with t 1e tie.

The invention further consists in the noveland improved general construction, whlch will be hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of em bodiment of the invention, it being understood,

however, that no limitation is made to the structural details therein exhibited, but that the. right is reserved to any changes, alterations,

and modifications which come fairly within the scope of the invention and which may be resorted to without departing from the spirit or sacrificing any of the advantages of the same. In said drawings, Figure 1 is aperspective view of a metallic railroad-tie embodying the principles of my invention. Fig. 2 is a plan view showing a plurality of ties with the rails mounted in position thereon. Fig. 3 is a transverse sectional view, enlarged,'take n' on the line 3 3 in Fig. 2. Fig. 4 is a sectional view, enlarged, taken on the line 4: 4 in "Fig. 2. Fig. 5 is a perspective detail view showing a preferred form of bolt or fastening device used in connection with the invention.

Corresponding parts in the several figures earth-engaging anchors which when the tie is placed in position will serve to prevent lateral displacement thereof and cause it to be retained in position with a great degree of security.

Upon the upper side of the body 1 and equidistantly from the ends thereof are formed two elevated longitudinal'ridges 3 3, having-beveled sides 4: 4 and flat upper faces 5, whichare to be planed off smoothly, so as to form seats for the rails which are to be mounted thereon. v Perforations 6 are provided which extend vertically through the body 1 and the ridges forming the rail-seats, each of the latter being provided with four such perforations, which are to be suitably disposed, so that fastening means fitted to said perforations will be adapted to suitably engage opposite sides of the seateflanges 7 0f the rails 8, mounted thereon.

The preferred fastening means used in connection with my invention consists of bolts 9,

for the reception of which the perforations 6 areinteriorly threaded. The bolts 9 have circular heads 10, the under sides of which are beveled, as shown at 11, to correspond with the customary bevel of the rail-flanges. Each bolt is crowned by a projection 12, constituting a wrench-seat, whereby it may be tightened into position.

The bolt-holes 6 may be placed in such a position that they shall strictly and truly aline with the rail-flanges; but it may be found preferable to leave a slight space or play (indicated in the drawings at' S) in order that adjustment may be had to preserve the gage between-the rails. Thus in the event ofexcessive wear upon the latter the innerfasteningbolts may be slightly loosened and the rails moved inwardly to the true position, after which the bolts may be retightened, the beveled heads of the bolts serving to prevent outward displacement of the rails: If desired, small metallic wedges may be driven between the rail-flanges and the shanks of the outer bolts, as shown at 7, thereby positively preventing the rails from spreading.

At points where the ends of adjacent rails abut upon each other a tie is to be placed under such abutting rail ends, as will be seen in Fig. 2 of the drawings. Fish-plates F of ordinary construction may be used to connect the rail ends, as such plates will not interfere with the use of the fastening-bolts herein described.

By this invention a rail-supporting device is provided which is simple, durable, and inexpensive and whereby the rails will be supported with the utmost degree of security and yet in such a manner that they may be adjusted whenever necessary to do so in a simple and expeditious manner and without interfering with the integrity of the fastening. The beveled 0r inclined sides of the rail-seats will shed moisture, and the contacting faces of the rails and the supporting device will thus be protected against corrosion.

Having thus described my invention, 1 claim 1. A metallic railroad-tie having elevated rail-seats and screw-threaded perforations extending through the seats and the tie, in combination with rail-fastening bolts having circular heads beveled upon their under sides and crown projections forming wrench-seats.

2. A metallic railroad-tic having elevated rail-seats, perforations in said seats. said perforations being spaced apart slightly in excess of the width of a rail-flange, and bolts engaging said perforations and having circular heads, beveled upon their under sides, and wrench-seats upon the upper sides of the boltheads.

In testimony that 1 claim the foregoing as my own I have hereto afiixed my signature in the presence of two witnesses.

HENRY HARDEN ASH LOCK.
