RAILROAD-TIE.

' Specificationof Letters Patent.

Application filed September 10, 1909. Serial No. 517,121.

To all whom it my concern.

Be it known that I, THOMAS LEE EvERE'rr,

a citizen of the United States, residing at Fairfield, in the "county of Jefferson and State of Iowa, have invented new and-use- .ful Improvements in Railroad-Ties, of

which the following isaspecification.

This invention relates to railroad ties, the

object of the invention being to provide a substitute for the ordinary Wooden railroad tie now in common use.

The tie hereinafter described, comprises a concrete body combined. with rail holdi'ng means embedded in and forming a part of the tie, doing away with the necessity of using the ordinary fish plates and bolts and economizing materially-in the cost of maintenance of the road by avoiding the necessity of tightening the bolts and fasteners from time to time.

With the above and other objects in view, the invention consists in the'novel construction, combination and arrangement of parts as herein fully described,; illustrated and claimed.

. In the accompanying drawings :Figure l is a perspective view of a railroad tie embodying the present invention, showing a section of a railroad rail applied thereto.

Fig. 2is a detail perspective view of one of the cushions. Fig. 3 is a similar view of one of the rail clamps. Fig. 4 is a detail perspective View of a double rail clamp adapted to bridge adjacent ties.

The body -of the tie indicated at 1 is composed of concrete and may be made of any desired length, width and depth, the length being sufficient to support the. rails.

In connection with each tie, I employ a pair of yokes, each yoke embodying a pair of upwardly curving and inwardly facing braces 2 having enlarged lower ends which are connected by a base 3 formed integrally with the bracesas shown in Fig. 1 at the left hand end. The said base 3 is recessed in its upper face as shown at 4 to provide forthe reception of a cushion block preferably of wood. In forming the recess fl, shoulders 6 are left at opposite sides of said recess; which shoulders are received in oppositely located notches 7. formed in the cushion 5, as shown in Fig. 2. Inthis way the cushion is securely locked in place in the yoke and between the braces 2-. The yeizes at opposite ends of the tie are connected by a tie bar 8 indicated by dotted lines in Fig.

1, the yokes being secured to the tie bar by bolts or rivets 9 or in any convenient manner. The central portion of the tie bar between the yokes'is depressed in the form ofan inverted arch as shown at 10, the said depressed portion together with the entire tie bar being embedded in the tie during the formation of the latter; The opposite extremities of the tiebar beyond the yokes are extended downward and are also embedded in the, tie.

In connection with each yoke, I employ a pa r of rail clamps each embodying a tapering base .12 having an inclined upper surface 13; the clamp also comprises a \"er' tical 'or upstanding flangele adapted to bear against the side of the rail, and a curved or U-shaped bend 15 which embraces the bottom flange of the rail, as shown in Fig. 1. The upstanding part 14 is provided on its outer side with an interlocking lug 16 while the upper extremities of the braces 2 t are provided with slots 17 to receive the lugs 16 of the rail clamps. In this way, an in- Patented May31, 1910.

terlocked engagement is cfiected between the rail clamps and the braces, as shown in Fig. 1,

Instead of employing a separate pair of clamps for each tie, the clamps may be elongated horizontally as shown in Fig. 1 or in other words said clamps may be made of suflicient length to bridge a pair of ties in which case each clamp may be provided with a pair oflugs 16 to be received in the notches 17 above described.

cushions 5, when a train passes over the joint, the rail clamps bear with greater tirinness and pressure against the rail and avoid any possibility of the rail slipping adjacent to the joint. The joint also provides for the necessary, expansion and contraction of the rails due to changesin the veather as,

it may work lengthwise between the rail clamps when relieved of the weight of the train. The rails are associated with the c lamps'and tie by. sliding the clamps endwise into engagement with said rails and" tie.

The joint hereinabove described 1S especially valuable on curved sections of a rail- "way' track as it not only provides forthe embedded in the-tie body.

necessary contractionand expansion but also prevents the tendency of the outer rail 'to spread on acurve. It is also within the i scope of this invention to use the clamp upon a continuous bed of concrete instead of separate ties as hereinabove described.

1'. A railroad tie comprising a tie body of concrete, yokes each comprising a pair of rail braces and an integral base connecting said braces and formed with a cushion receiving recess between the braces, and a tie bar connectingthe yokes and having its central portion depressed between the yokes and its opposite extremities projected downward beyond the yokes,'the said tie bar being 2. A railroad tie comprising a tie body of I v concrete,yokes each embodying a pair of rail braces and an integral base connecting said braces and formed with a cushion receiving recess between the braces, a tie bar connecting the yokes and embedded in the tie body, cushion blocks having-notches to receive portions of the yokes, and rail clamps having ceiving recess between braces which extend under the rail and rest upon the cushionblocks and upstanding portions which extend between the rail and braces and interlock with the braces.

3. A railroad tie comprising a tie body of concrete, yokes each embodying a pair of rail braces and an integral base connecting said braces and formed with a cushion rethe braces, tie bars connecting the yokes and embedded in the tie body, cushions fitting in said recesses and having notches to receive portions of the yoke, and rail clam s having braces which extend under the rai and rest on the cushion blocks, upstanding portions which extend between the rail and braces, and lugs on said upstanding portions which fit into notches in the braces.

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