the chairs can be knocked out laterally from their seats 4: and other chairs substituted and the rails spiked to them.

The tie 1 is reinforced by parallel sets of horizontal rods 8, each set being composed of a plurality of rods arranged above each other. Flanking the'chairs 5 and extending into the raised parts 3 of the tie 1,. are upright reinforcing rods 9 of which preferably. a plurality is employed. on each side of each chair 5. The upright reinforcing rods have vertical lower parts 10 and inclined upper parts 11, the latter being preferably substantialiy parallel to the sides of the chairs 5, the bends or angles of the upright reinforcing members being shown at 12. The upright reinforcing members 9 are arranged in alternation With the horizontal reinforcing rods 8, as shown in Fig. 4.

The foregoing reinforcing system is Well adapted to resist breaking or crackingof the tie, at-the centerbelow the part 2 and breaking on of any part of the ends of the tie due-to any weakening thereof by the provision of the seats 4t. llhe upper parts 11 of the rods 9 reinforce the Walls. of the seats 4-.

Letters Patent, is I A rail tie provided with sets of upright reinforcing rods in its end parts and with longitudinal reinforcing rods arranged in series which alternate with the series of up right rods, and Wooden rail chairs embedded in the tie and located between the respective sets of upright reinforcing rods aforesaid with the sides of said chairs arranged substantially parallel to parts of said upright reinfo. ting rods. i

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