.To all whom it may concern:

'Be it known that ,1, ALBERT Cor'roM. a citizen of the United States, residing at Ghillicothe, in the county of Wapello and State of Iowa, have invented certain new and useful Improvements in Cross-Tie Constructions, of which the following is a specification.

The present invention relates to certain new and useful improvements in track construction; and more particularly to a novel formof tie and means for securing the rails thereto.

The object of the invention is to provide a simple and eflicient device of this character which can be installed at a comparatively smallfirst cost and which requires but a small amount of attention to be kept in repair and maintained in operative condition.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accompanying drawings, in which: 1

Figure 1 is a perspective view illustrating the invention. Fig. 2 is a sectional view through the rail clamp.

Fig. 3 is a top plan view of the same. Fig. 4 is a detail.

view of the locking bar. Fig. 5 is a longitudinal sectional view through the device. Fig. 6 is a transverse sectional view through a track constructed in accordance with. the present invention. Fig. 7 is a detail view of the bearing device. 8 is a detail view of the nut lock employed in connection with the nuts capping the rods extending'transvers'ely across the track; Fig.9 is a detail view showing the method of linking together the various bearing members.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

In accordance with the present invention the ties are composed of spaced sections 1 extendinglongitudinally of the track, the said sections being located under each of the rails, and being preferablyformed of concrete or some similar plastic material. If found desirable 1ongitudi nal reinforcing wires 3 may be embedded in the concrete sections, and these wires are preferably formed at intervals with enlarged portions or knots 4 which prevent any longitudinal slipping thereof.

The clamping device employed for securing the rails 5to the ties 1 comprises a base plate 6 provided at oppo- I site sides with the downwardly extending flanges 7 designed to embrace the tie. Mounted upon the upper face of thebasc plate 6 is the bearing block 8 whi ch forms a support for the base of the rail. Mounted upon one side of the bearing block 8 is a rail engaging member 9 which fits over the basal flange upon one side of the rail. Spaced extensions 10 project laterally fromthe opposite side of the bearing block 8, the said extensions resting upon the base plate 6 and being of less depth than the bearing ,block; 8. At the outer end of each of these extensions 10 is located an upwardly extending flange 11, the extremity of which has a hooked formation as indicated at 12. Resting upon the extensions 10 and lying flush with the upper face of the bearing block 8 is the clamping barl 3 which is provided upon its upper face with a rail engaging member 14 similar to and cooperating with the before mentioned rail engaging member 9 to clamp the rail securely in position. Projecting downwardly from the clamping bar 13 and swinging freely between the spaced exten sions 10 is a wing 15 which is engaged by the extremity of a clamping bolt 16 extending transverseiy through the bearing block 8.

In the operation of the clamp it will be readily apparent that the hooked extremities 12 of the upwardly extending flanges 11 engage the outer edge of the clamping bar 13 so that the latter canonlybe removed,

from position by first turning it about a'longitudi is'held rigidly in position.

Interposed between the tie 1 and the rail clamping I device previously described is a bearing member 17 shown in detail in Fig. 7 and comprising essentially an elongated metallic plate 18' having the spaced Wooden blocks 19. secured to its upper face while a wooden strip 20 somewhat shorter than the metallic plate. is secured to its lower face, the said members being connected by bolts or similar fastening means. The wooden strips 20 rest upon the upper faces of the concrete ti'e sections 1 and have approximately the same length as the said sections 1, while the end portions of the metallic plates 18 project outwardly and are-formed with the openings 35. The bearing members upon adjacent tie sections 1 are connected by means of link members 36 which engage the openings 35 in the'metallic plates 18. In the present instance eye engaging one of the openings 35 and at the opposite end with a hook extending through the opening 35 in the adjacent bearing member, and the said hook may be locked against accidental release by means of a'key or similar member 37. The base plate-6 of the plate and the metallic plate 180i the bearing memthese link members 36 are formed at one end with an 1 0 tightly, but fit loosely upon the stems 23. Any approved type of nut lock may be employed her isa cushioning member or that 21 which tends to I decrease tlienoiseand prevent the hammering of the concrete sections 1 as the rolling stock passes thereover. Witlrthis construction the pressure of the rails is distributed over a comparatively large area of the tie and the life of the latter is thereby very materially prolonged. Under some conditions it may be found desirable to substitute a plain wooden block let into the upper face-of the concrete tie for the specific form of bearing member 17 just described.

Extending transversely across the track and con nectingco rresponding clamping members upon oppo flanges 7 and are capped by the nuts 26 which serve to clamp the outer flanges? securely against the shoulders 27 at the inner ends of the threaded studs 25."

I The stems 23 are received by openings 28 inthe con-.

crete ties 1, the said openings being enlarged and vertically elongated so that the tie members 2 have no 'direct bearing upon the concrete ties 1. It might also be mentioned that the openings in the outer flanges 7 of the clamping members are somewhat smaller than the openings on the inner flanges 7 and that the said inner flanges are not clamped or held in connection withthe nuts 26 in order to prevent the same from working loose, but this result is preferably accomplished by means of the'construction shown in the drawings in which the corners of the nuts 26 are formed upon their inner faces with .the 'grooves 29, one of which is designed to register at each quarter turn of the nut with a vertical groove 30 in the outer flange 7'. 'Slidably mounted within the vertical groove 30 is a locking pin 31 designed to engage one of the grooves 29 of the nut and provided at its lower end with a nose or catch 32 which is adapted to engage the nut toprevent accidental displacement of the locking pin, and at its upper end with the outwardly extending linger-piece 33.
