RAILROAD-TIE.

Specification of Letters Patent. Patented Dec. 25, 1917.

Application filed May 17, 1917. Serial No. 169,306.

To all whom it may concern:

Be it known that I, EDWARD W. CARROLL, a citizen of the United States, residing at Weston, in the county of Lewis and State of Vest Virginia, have invented a new and useful Railroad-Tie, of which the following is a specification.

The present invention appertains to railroad ties, and aims to provide a novel and improved substitute for the ordinary wooden cross tie, and which is of such construction as to more securely hold the rails and to have a much longer life thanthe wooden tie now used.

The invention has for its object the provision of a railroad tie embodying sleepers of concrete or other suitable material for supporting the rails, and novel means for mounting the rails on'the sleepers and for connecting the sleepers in pairs to hold the rails in gage.

It is also the object of the invention to provide a railroad tie which is comparatively simple and inexpensive in constructlon, and which will be practical and efficient in use.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination 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 l is a plan view of the tie, the securing nuts of one sleeper being removed and the corresponding portion of the rail being broken away, 7

Fig. 2 is a section of the line 22 of Fig. 1.

In carrying out the invention, each tie embodies a pair of sleepers 1 of concrete or other suitable material which are embedded in the road bed, and over which the rails 52 pass. equivalent yieldable material are placed on the sleepers, and the rails seat on these plates, whereby to cushion the shocks, and allow a slight yielding movement of the rails on the sleepers. These plates are disposed transversely on the sleepers underneath the rails.

Cushion plates 3 of wood or In order to secure the rails on the sleepers, transverse metallic strips 4; are seated on the sleepers and alternate with the platesv 3. Pairs of upstanding bolts 5 have their lower terminals embedded in each sleeper and extend upwardly through apertures in the strips t so that the rail 2 extends between the bolts, said bolts having their upper terminals projecting upwardly across the edges of the base flanges of the rail, whereby to prevent the lateral displacement of the rail on the sleeper. The ends of the strips 7 are bent downwardly to overlap the sides of the sleeper, whereby to assist in holding the parts in place, and nuts 8 are threaded onto the upper terminals of the bolts 5 to clamp the base flanges of the rail on the cushion plates 3. The strips 4 are thinner than the plates 3, so that the rails will seat on the plates 3 instead of on the strips 4. The lower ends of the bolts 5 can be threaded into nuts 6 embedded in the sleeper 1, permitting of the removal of the bolts, if this is desired, although the bolts can be anchored in the sleeper in any suitable manner.

Upstanding bolts 9 are also anchored within each sleeper adjacent to the pairs of bolts 5, and each strip 4 has a lateral extension or wing 10 projecting therefrom adjacent to one end and through which the corresponding bolt 9 extends upwardly, whereby to brace said bolt 9 against lateral displacement.

Transverse rods 11 are disposed between the sleepers to hold them in relative position, and the ends of said rods have eyes or hooks 12 embracing the upper terminals of the bolts 9 and seating on the Wings 10. Nuts 13 are threaded on the bolts 9 and clamp the eyes 12 in place. The rods 11 are resilient, whereby to permit of the relative flexing of the sleepers, due to the strains imposed thereon by a train passing over the track.

In case of repairs, the rods 11 can be readily removed by moving the nuts 13, and by loosening the nuts 8, the rails can be jacked up on the sleepers, and the cushion plates 3 removed and replaced, said cushion plates being independent of the strips 4.

Having thus described the invention, what is claimed as new is 1. A railroad tie embodying a sleeper, transverse cushion plates thereon for supporting a rail, transverse strips on the sleeper alternating with said plates, and

pairs of upstanding bolts embedded in the sleeper and projecting upwardly through said strips to receive the rails therebetween, said bolts having nuts thereon for clamping the rail on the cushion plates.

2. A railroad tie embodying a pair of sleepers, strips on the sleepers, pairs of bolts embedded in the sleepers and extending upwardly through said strips for receiving rails therebetween, said bolts having means for clamping the rails on the sleepers, other bolts embedded in the sleepers, said strips having portions engaging the second mentioned bolts, and transverse rods having their terminals embracing the second mentioned bolts.

3. A railroad tie embodying .a pair of sleepers, transverse cushion plates thereon forsupporting the rails, transverse strips on the sleepers alternating With said cushion plates, pairs of bolts embedded in the sleepers and extending upwardly through said strips for receiving the rails therebetween, nuts threaded on said bolts for clamping the base flanges of the rails on said cushion plates, other bolts embedded in the sleepers, said strips having portions engaging the second mentioned bolts, rods having terminal eyes embracing the second mentioned bolts on said portions of the strips, and nuts threaded on the second mentioned bolts and lamping said eyes in-place.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two Witnesses.

EDWARD WV. CARROLL.
