The hori- 16 0 zontal pull on the tie rods, at the same time, causes them to depress the rail down and to press -it still harder against the road bed. This action is illustrated in Fig. '14, the depressed position being shown with dotted lines.

A modified arrangement is shown in Fig. 6. Here a single tie rod is used for the rail 2. Its lower end is pivotally oonnected'with a clamp 22 which encircles a wooden beam 23. there being one beam'foreach rail. The two beams are connected by wooden boards 2&- fastened to the beams by spikes 25. These beams with the boards form a common slab for tworails. d

Another modification is shown in Fig, 11 which is especially adapted for preventing transverse displacement of the track rails, for instance, on the curves. For this purpose the rails are connected with a metal tie or bar 26 fastened to ordinary ties 19 with bolts "27. The rail is fastened to the bar 26 by means of clamps 28 and bolts 29. Instead of using a bar 19 the rails can be supported on brackets 30 (Fig. 10) bolted to the tie with bolts Stand provided with supporting lugs 32 for the side of the rail similar to ordinary fish plates. The tie rod s33 (Fig. 11) extend from the rail clamps to clevis bolts Sin large slabs '34 extending under both rails. The tie rods-extend at an angle and cross each other so as to offer resistance to either direction of the rail shift, to the right or to the left. 7

In cases when the side strains are very large adouble set of cross tie rods 35'may be used l2) the rods extending inehoth directions from each rail to the large slab 36.

A combined arrangement is shown in Fig. 13 with longitudinal tie rods 11 and transverse rods 33 attached to the same slab 37 which extends under both rails 52. Ther'ail attachments 38 are shown of a simplified form adapted to be welded: to thelower surface of the. rail and provided with clevises 39 for bolts 40.. 1 7

Important advantages'of my arrangement arethat it provides a means for securely holding the rails on the tracln'preventing' them from longitudinal and transverse displacemcnts under heavy strains from passingtrains. thereby rendering the track more per manent and eliminating necesslty for frequent repairs andrelaying of the track rails.

1 claim as my invention: 1. in a track reta ning device, the combination with horizontally extending massive slabs buried in the ballast under track rails. and tie rods extending from said slabs to said 7 rails and pivotally connected with said slabs and said rails, said slabsbeing placed in depressions in. the ground under said ballast. p 23111 a track retaining devic'e,,the combination with "horizon'tally extending massive slabs buried in the roadbedunder trackrails'. tie'rods extending fromv said slabs to said rails. and metal members permanently connected with said slabs said rods being removably connected with said metal members and said rails.

3. In a rail retaining device, the combination with slabs buried under the ballast under track rails, tie rods extending from said slabs to said rails, channel-shaped members placed longitudinally with their edges against the bottom surface of the rails, clamps adapted to hold'together said members and said rails, bolts passing through said clamps and said members in a cooperation with said clamps, and meansto removably connect the ends of said tie rods with said channelshaped members.

In testimony whereof I affix my signature.
