RAILROAD-TIE.

Specification of Letters Patent.

Patented May 21, 1907 Application filed February 8,1907. Serial No. 356,355.

Keokuk, in the county of Lee and State of Iowa, have invented certain new and useful Improvements in Railroad-Ties, of which the following is a s ecification,-referen'ce being had therein to t e accompanying drawings.

This invention relates to improvementsin railroad ties, and the object of the invention is the provision of a tiewhich will prevent sagging of the rails at the joints thereof.

' 'att A further object of the invention is the provision of ties arranged to extend lon itudinall ofthe rails to prevent sa ging t ereof lie joints, which tiesare rigir 1y connected to prevent spreading of the rails. A further object of the invention is the .provision of improved means for reinforcing the wooden ties commonly in use, and pre: serving the same from decay.

Other objects of the invention will be apparent from the detailed descriptionhereinafter, when read in connection with the ac-,

companying drawings forming a part hereof, wherein a preferable embodiment of my invention is shown and wherein like numerals of reference refer to similar parts in the several views.

In the drawings, Figure 1 is a plan view of.

a section of railroad track equipped with our improved ties. line 2-2 of Fig. 1. Fig. 3 is a cross section on line 33 of Fig. 1.

Referrin drawings, A indicate the rails, which are supported u on cross ties placed at suitable intervalsan longitudinal ties interposed between the cross ties.

The cross ties each comprise an elongated metallic trough. B,- which is preferably formed of sheet steel, and in which is positioned the usual wooden tie B, to which the bases of the rails A-A are ada ted to be spiked in the usual manner. T e wooden ties B are secured within the trough mem bers B by means of U-shaped clips 0, which are preferably stamped from sheet steel, and which are secured across the tops of the trough members, the arms of said clip being arranged to overlie the sides of said trou h members and being riveted thereto. T e

Wooden ties B are held against longitudinal.

movement in the trough members B by Fig. 2 is a cross sectionlon now more particularly to the r means of spikes b, which are driven therein and the heads of which engage opposite edges of the clips C.

In the form of-our invention disclosed in the drawings we have shown the trough members B as each provided with two wooden ties B, which is a very economical structure, as it permits of the utilization. of the old or worn ties which have hitherto had to be discarded. It will be obvious, however, that a single tie may be secured within the trough members if desired. The longitudinal ties each comprise an elongated trough member C which is preferably stamped'frorn sheet 0 The ends of the trough members C are thereof whicv are designed to overlie the tops of the ties B secured within the trough mempassing therethrough and en aging sai ties.

. Interposed between the ad the longitudinal trough members C are sleeves 0, through which pass tie rods 0 the opposite ends of which pass through the side walls of the trough members 0 and the ties C seated therein. The tie rods 0 are each provided at one end with a suitable head and at the other end with a nutor other fasten ing device, so that the sides of the trough gagement with the ends of the sleeves c and the longitudinal ties and the rails carried thereby may be maintained at the proper distance apart, thereby preventing any spreading of the rails.

The" bottoms of the .trou h members B and C are each provided wit a plurality of any water which may accumulate in said trough. It will be seen from this construction that the metallic troughs not only serve to strengthen and reinforce the Wooden ties, but also toprot'ect them from injury and de-' ca r We do not desire to limit ourselves to the precise form and construction shown in the drawings, as it is obvious that many minor changes may be made therefrom without departing from the spirit of the invention, as defined in the appended claims.

Claims.

1-. In a railway track structure, a pair of longitudinal ties, a plurality of sleeves interposed between said ties, and tie rods conbers B, and are secured thereto by s ikes members 0 may be drawn tightly into enapertures a therein to permit the escape of steel, and in which is secured a wooden tie closed and are provided with laterally projecting flan es 0 extending from the tops jacent faces of necting said ties and passing through said sleeves.

2. In a railway track structure, separated ties each comprising a metallic trough, a Wooden tie seated therein, and tie rods conheating said ties, the extremities of which pass through the sides of the metallic troughs and the ties seated therein.

3-. In a .railway track structure, a pair of cross ties, a.pai-r of longitudinal ties interposed between said cross ties and having their ends secured thereto, a plurality of sleeves interposed between the adjacent sides of the longitudinal ties, and tie rods connecting the longitudinal ties and passing through said sleeves.

4. In a railroad track structure, a pair of separated cross ties and longitudinal ties in terposed therebetweemeach of said longitudinal ties comprising a metallic trough'having ilanges extending from the ends thereof and overlying the cross ties and a Wooden tie secured within said trough.

5. In a railroad track structure, a pair of cross ties each comprising a metallic trough and a wooden tie seated therein, and a pair of separated longitudinal ties interposed therebetween, each of said lon itudinal ties c 11- prising a metallic trough aving fianges' extending from the ends thereof, and 0V6 rly' ng the cross ties and a wooden tie seated nsaid metallic trough, and tie rodsconnecting said
