RAIL-FASTENING DEVICE.
Specification of Letters Patent.
Patented April 23, 1907'.
Application filed January 9, 1907. Serial No. 351,512.
To all zul/1,0m it 71mg/ conc/1771,.-
Be it known that l, JAMES l). (Jammu, a subject of the King of Great Britain, residing at Denison, in the county of Grayson and State of Texas, have invented certain new and useful Improvements in lail-llastening Devices; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to rail-fastening devices, and is more particularly designed for securely holding in place the rails of street railway tracks where the paving of the street on which such tracks are laid is placed upon a concrete or cement base, and its use obviates the necessity of the employment of crossties or tie rods between the rails.
In the accompanying drawing Figure is a cross section of a street pavement showing the rails and the securing device applied thereto Fig. 2 illustrates a modified form of the fastening device.
As shown in the drawing, l l designate the rails of a street railway track, and 2 the securing means therefor, consisting of a flat bar of iron bent at each end in opposite directions, and at substantially a right angle to the main or body portion thereof, the upper end 3 being bent inwardly and the lower end 4 outwardly therefrom. The upper bent portion 3 is preferably approximately one-half the length of the lower bent portion 4, and is bent at a slight upward angle tothe main portion 2 whereby it fits snugly over the incline of the flange 5 of the rail over which it laps as shown.
As stated, the fastening is adapted for use in the securely holding of street railway rails Where the pavement of Vthe street on which such rails are employed is laid upon a concrete or cement foundation, and in which form of pavement the cement or concrete foundation is first laid and then a layer of sand is placed thereon and upon the latter is laid the surface pavement of vitrifed. brick, granite block or other paving material. l/Vhile the foundation is in a soft or more or less plastic condition, the rails are placed therein and trued to the proper gage, and the fastening devices 2 are also placed in position with their inturned portion 3 lapping the flanges of the rails, and the concrete orcement packed around the same, whereby when such concrete or cement hardens it becomes a solid mass with the fastening devices embedded therein, and securely holding the rails in place. The lower inturned portion 4 of the fastening devices, as will be seen, extends .far enough down into the concrete or cement lorming the base of the pavement as to be securely held by the mass of material above the same, and the body portion 2 of the fastening devices and the bent ends 3 are completely surrounded by such concrete or cement constituling the foundation of the pavement. lt will be understood that any number of these fastening devices may be applied, and that the same are arranged at proper intervals on each side of the rails and overlapping the flanges thereof and serve to securely hold the rails in position. By this fastening means, the use of all cross-rods or other lateral fastenings between the rails is rendered unnecessary.
The form of the securing device may be changed, and its structure may be modified as regards the size of its straight or bent portions, without departure from the spirit of the invention.
Having thus described my invention, what l desire to claim and secure by Letters Patent is l. The combination with a street pavement having a cement or concrete foundation, of a fastening device for a railway rail adapted to be embedded in the pavement, said fastening device comprising an end portion adapted to engage the flange of the rail and a body portion extending down into the pavement below the rail to form an anchor.
2. The combination with a street pavement having a cement or concrete foundation, of a fastening device for a railway rail adapted to be embedded in the pavement and comprising a straight body portion, and having its ends extending at an angle thereto, whereby its upper end adapted to overlap the flange of the rail and its lower end to anchor the structure in position as set forth.
ln testimony whereof l aflix my signature, in presence of two witnesses.
JAMES P. CRERAR.
