Specification of Letters Patent.

Patented Dec. 10, 1912.

Application filed December 15, 1911. Serial No. 665,959.

To all whom it may concern:

Be it known that we, ALBERT R. Fnns'rnn- MACHER and WVILLIAM E. WVILSON, citizens of the United States, residing at Harrisburg, in the county of Dauphin and State of Pennsylvania, have invented a new and useful Improvement in Reinforced-Concrete Railroad-Ties, of which the following is a specification.

his invention relates to a combined con crete tie, properly reinforced, and a railroad chair, the tie-being especially constructed to support and receive our particular construction of chair. The tie and chair combined providing a firm support for the track rails, and securely holding them against all danger of lateral displacement.

he invention consists of the novel features of construction hereinafter described, pointed out in the claims and shown in the accompanying drawings, in which: I

Figure 1 is a vertical longitudinal section, centrally broken away. Fig. 2 is a plan view, the end portion being broken off, and the central portion being broken away. Fig. 3 is an end elevation of two ties illustrating the position of the fish plates relative to the ties. Fig. 4 is a section on the line 4Ct of Fig. 2. Fig. 5 is an enlarged plan View of an end portion of one of the ties, the chair and rail being removed.

In these drawings 1 represents a concrete tie the end portions 2 each is beveled, and these end portions are also centrally and longitudinally recessed as shown at 3,-the recesses 3 extending inwardly to a line parallel to and adjacent the outer faces of the track rails 4. A longitudinal bore extends through the tie opening into the recesses 3, and a bolt 5 extends through the bore, the ends of the bolt being threaded and projecting into said recesses. This bolt is inclosed in pipe or sleeve sections 6 and the tie is also provided with vertically arranged recesses 7 which communicate at their lower ends with the longitudinal bore, suitable eye bolts 8 are placed vertically in the recesses 7, the bolt 5 passing through the eyes of the bolts 8. There are preferably two of the bolts 8 for each tie and they are arranged between the track rails.

The chair consists of three pieces, that is two members 9 which fit within the recesses 3 and bear upon the outer faces of the rails, the members 9 being suitably angled, and

they suitable lock nuts 10 threaded upon the projected end portions of the bolt. The third member of the chair consists of a central section which comprises a plate 11 extending longitudinally upon the central portion of the tie and preferably fitting in a suitable sunken or depressed portion 12, shown most clearly in Fig. 5. This plate 11 when in position incloses the upper ends of the recesses 7 and is suitably perforated to receive the upper ends of the eye bolts 8, upon which nuts 13 are placed, said nuts bearing upon the bolt 8. This plate is provided with angled end portions lat which bear upon the inner faces of the base and Web and complete the chair, the rail being firmly held between said angled portions 1A and the members 9. Any suitable packing material 15 may be placed transversely across the tie for the rail base to rest upon.

The tie is further strengthened by means of inverted T-shaped beams 16 which are placed in the lower port-ion of the tie and is also reinforced by suitable wires 17 of twisted steel, which are arranged throughout the tie in any desired manner.

hat we claim is:

1. The combination with a concrete tie having recessed end portions, a chair comprising end portions fitting said end recesses and engaging the outer faces of the rail a central portion resting upon the tie and engaging the inner faces of the rail, eye bolts arranged vertically in the tie and passing through the central portion of the chair, nuts working upon said eye bolts, a bolt passing through the end members of the chair and longitudinally through the tie, and bolts thereupon.

2. A device of the kind described, comprising a concrete tie having end recesses, having a longitudinal bore connecting said recesses, and having vertical recesses opening through the top of the tie and communicating with said bore, a chair formed of central and end portions, the end portions fitting the end recesses of the tie, and the central portion of the chair covering the last mentioned recesses, and means arranged in the bore and in the vertical recesses of the tie for locking the end members of the chair and the central member of the chair together.

3. A device of the kind described, comprising a tie having its end portions reare held in place by the bolt 5 and by cessed, and having a longitudinal bore connecting said recesses, and vertical recesses opening through the top of the tie and into said bore, a chair comprising angled outer end members seated in said end recesses of the tie, and engaging the outer faces of the rails, a central chair section embedded in the top of the tie and covering the vertical recesses, said central section having angled end portions engaging the inner faces of the rails, a bolt passing through the outer end sections of the chair and through the longitudinal bore of the tie, eye bolts arranged in the vertical recesses of the tie and passing through the central chair section, the first mentioned bolt passing through the eyes of the eye bolts, and sleeves arranged :lElpOIfi said bolt, as and for the vpurpose set ort 4:. In a device of the kind described, a concrete tie having end recesses, having a longitudinal bore connecting said recesses, and vertical bores communicating With the longitudinal bore, angled chair sections arranged in the end recesses and adapted to engage outer sides of a rail, a central chair sect-ion extending from rail to rail and having openings alining with the vertical bores, a bolt running through the longitudinal bore and connecting the end. chair sections, and means extending through the vertical bores and securing the central chair section to said bolt.
