CONCRETE RAILROAD-TIE.
Specification of Iletters Patent. Patented J i28 1914;.
Application led October 2, 1913. lSerial No. 793,008. f
To all whom it may concern.'
Be it known that I, RICHARD lHENRY JOHNSON, a citizen of the United States, re. siding at Creston, inthe county of Lincoln A second object of my inventionis to pro;y
vide a railroad tie of maximuinstrength and moderate weight.
vide a railroad tie having a wooden core and a concrete or cement exterior in which the cement shall be fastened to the core as firmly as possible.
A final object of my invention resides in the particular arrangement and combination of parts hereinafter described.
In the accompanying drawings, Figure 1 is a detail view showing my improved tie arranged to support a rail and showing the tie in longitudinal section. Fig. 2 is a view similar to Fig. 1 but showing the tie as supporting a rail on a curve, and illustrating the different fastening plates used in the curved construction. Fig. 3 is a cross sectional view of a tie such as is shown in Figs. 1 and 2. Fig. A is a detail view illustrating the manner of arranging certain of the reinforcing wires in the neighborhood of a bolt hole. Fig. 5 is a perspective view showing one of the fastening plates used for ho lding the rail in place. Fig. 6 is a perspective view showing the exterior of one of my ties.
Throughout the separate views the same part is shown by the same reference character.
Referring more particularly to the drawings, 1 indicates a tie made according to my invention, which is provided with a core 2,
preferably of wood, and an external coating such as 3 of cement or concrete. As clearly shown in Fig. 3, the core 2 is of generally rectangular cross section but is provided with dove tail recesses such as 4 4, one in each face of the core. The cement covering or envelop is packed tightly `into the recesses A and consequently is held firmly to the core 2. y' I have shown four of the recesses l butfevidently certain of them may beomitted ifdesired.' Y
The concrete lenvelop 31 is provided with metal reinforcing of special vdesign `whichl not only strengthens the tie against bending butV also `furtherfbinds the envelop to the ySuch reinforcing means comprisesklongitudinal rods 5-5 of which there are four, one adjacent each corner of the core 2. kThese rods 5 run parallel to the longitudinal .edges ofthe core being slightly removed therefrom and are surrounded by a rein-A forcing ,wirefy which is, y.wounds spirally I around the outside of the rods 5. As clearly A third object of my invention is to proshown in Figs. .1 and 2, the spiral reinforcing wires 6-6 extend from one end of the tie 1 tothe other. l
Near each end of the tie 1 are two bolt holes as'clearly shown in Figs. 1 and 2, and as illustrated in detail in Fig. 3. These bolt holes are indicated by reference character 7 `in Fig. 3 and, as shown in Fig. 4, thereinforcing wire 6 is bent into a loop around the bolt holes as shown at 8.
Referring again to Fig. 3,v it will be noted that the wire 6 is shown asinterrupted at the point 9. This is merely to call attention to the fact that the wire is wound spirally and that the ends overlap without ybeing united. It will be seen from Fig. 3, moreover, that the lower end ofthe boltl hole 7 is countersunk as at 10 so as to receive the head of the bolt. y
The tie 1 is intended to be used as shown in Figs. 1 and 2 in combination with fastening plates such as 11-11 which arek arranged on opposite sides of the rail 12 and which are fastened to the tie 1 bv means of bolts such as 13-13 mounted in the hole 7. The preferred form of plate 11 is illustrated in detail in Fig. 5, and comprises a flange 14C adapted to rest on the upper surface of the f tie and which is provided with a hole 15 for receiving the bolt 13. The plate 1l also has a shoulder 16 adapted to fit against the edge contact not only With the top of the flange, but also With the entire length of the Web of the rail on one-'side thereof. 1 l A It Will be understood that While I have shown and described the preferred form of my invention, I do not Wish to be limited thereto but contemplate all modiications and rearrangements thereof such as are em-v braced Within the terms of the appended claims. i
Having thus described my invention, What I claim, is
1. A railroad tie comprising a plurality of longitudinal rods, a Wire Wound spirally around said rods exterior thereto, concrete enveloping said rods and Wire, said tie being provided with bolt holes and said Wire being looped around said holes.
2. A railroad tie comp-rising a plurality of longitudinal reinforcing rods, a circumferential reinforcement embracing said rods and concrete embracing said rods and circumferential reinforcement, and a Wooden core for said concrete and closely surrounded thereby, said rods being placed adjacent the edges of said core. a
3. A railroad tie comprising in combination, a central wooden core provided with one or more longitudinal dove-tailed grooves therein., and a concrete envelop surrounding y said core and locking in said grooves.
4C. A railroad tie comprising in combination, a central Wooden core provided with one or more longitudinal dove tailed grooves, a plurality of longitudinal rods arranged near the corners of said core, a circumferential reinforcement comprising a Wire Wound spirally around said rods, and a concrete envelop surrounding said core, rods and Wire, and interlocking With said dovetailed grooves.
In testimony whereof I afx my signature in the presence of two Witnesses.
RICHARD HENRY JOHNSON.
