@ET/JUE 1i. 50S/UZ Z5, @LOM/55 om Patented Oct. 10, 1950 RAIL FASTENING DEVICE Arthur R. Schulze, Youngstown, Ohio, assignor to Carnegie-Illinois Steel Corporation, a corporation of New Jersey f Application September 9, 1949,A Serial No. 114,870

6 Claims. (Cl. 23S-349) This invention relates to a rail fastening device and is a continuation-in-part of my copending application, Serial No. 752,775, filed June 5, 1947.

The rail fastening device described in my copending application is satisfactory in most respects, but it is necessary to limit the thickness of the spring clip because of the amount of deflection required to insert the clip through the inverted U-shaped member. In order to have minimum corrosion effect, it is desired to use a thicker but narrower spring clip which will give minimum surface area in relation to the cross section. Also, I have found that it is necessary to make adjustments as the clip becomes worn and the only way in which this can be done in my previous application, is by the use of shims.

It is therefore an object of my invention to provide a rail fastening device which can be adjusted to compensate for wear.

Another object is to provide such a device which will last for a long time.

These and other objects will be more apparent after referring to the following specification and attached drawings, in which:

Figure 1 is a top plan view of the device;

Figure 2 is a sectional View taken on the line II--II of Figure l;

Figure 3 is a view, similar to Figure 2, showing a slight modification of my device;

Figure 4 is a top plan View of another embodiment of my device;

Figure 5 is a sectional View taken on the line V--V of Figure 4; and

Figure 6 is an enlarged View showing a, detail of Figure 5.

Referring more particularly to the drawings, the reference numeral 52 indicates a standard tie plate which is mounted on the tie in the usual manner and which is provided with the usual rail seating portion 54 for receiving the flange 56 of a rail. An inverted U-shaped member 58 is welded to the base plate 52 on each side of the rail between the seat portion 54 and the edge of the plate. The top inner surface of the member 5B is provided with a plurality of serrations 60 therein which extend generally parallel to the length of the rail. A spring clip 62 passes through the opening 64 in the U-shaped member 58 with one end bearing on the tie plate 52 and the other end bearing on the top surface 66 of the rail base. The inner end of the clip B2 is bent upwardly at 68 so that it may be driven into position until it abuts the rail web 10 which limits its inward movement. A serrated wedge shaped locking key 12 is provided in the opening 64 between the top 2 of the clip 62 and the serrations 5l). The bottom surface 74 of the key l2 is arranged in the opening $4 at a slightly steeper angle than the top surface 66 of the rail base. The difference between the two angles may be termed a difieren-1 ber 58 and the other jaw face contacts the large end of the serrated key 72. The jaws of the tongs are then moved together to slip the key l2 into position. When it is desired to closely control the amount of pressure applied to hold the spring clip 62 on the rail, hydraulically operated tongs may be used with the hydraulic pressure being varied as desired.

If desired, the locking key 12 and serrations 60 can be arranged so that the large end of the locking key will be adjacent the rail as shown in Figure 3. In this case the locking key can be forced into place by means of a lever having one end bearing on the web 'l0 of the rail.

The device can be disassembled by placing a block on the top surface of the spring clip `62 and pressing down on it with `a pinch bar having its inner end under the rail head.

Figures 4, 5 and 6 show another embodiment of my inventionin which an inverted U-shaped member is provided but the top of the opening 82 in the U-shaped member, instead of being a constant slope, is provided with two different slopes. Substantially one-half of the under surface is arranged at a differential angle 84 with the top surface of the rail base. The spring clip 85 is shaped as shown with a substantially horizontal portion 86 and sloping portion 88. The ends of the clips are bent upwardly at 90 and v92, respectively.

The clip 85 is installed by driving it into position with its surface 94 being compressed in the manner described more fully in my copending application. The inward movement of the clip is limited by contacting the end 90 with the web of the rail. This device, like that of Figure 1, may be used in conjunction with a serrated wedge.

While several embodiments of my invention have been shown and described it will be apparent that other adaptations and modifications may be made without departing from the scope of the following claims.

I claim:

1. A rail fastening device comprising a tie plate having a seat portion for the base of the rail, a member secured to said tie plate at a point intermediate the seat portion and the edge of the plate, said member having an opening therethrough with the top surface thereof being spaced from the top of said tie plate, said top surface having a plurality of serrations therein extending generally parallel to the length of the rail, an elongated spring clip extending through said opening with one end of said clip bearing against the top of the rail flange and the other end bearing against the top of the tie plate, and a serrated wedge shaped locking key in said opening between said clip and said top surface, the serrations in the locking key being shaped to fl into the iirst named serrations.

2. A rail fastening device according to claim 1 in which the bottom surface of the locking key is -arranged at a steeper angle than the top surface of the ange of the rail.

3. A rail fastening device according to claim 2 in which the distance between the top of the plate and the underside of the Wedge is substantially greater than the thickness of the plate.

4. A rail fastening device comprising a tie plate having a seat portion for the base of the rail, an inverted substantially U-shaped member secured to said tie plate at a point intermediate the seat portion and the edge of the plate, the underside of said U-shaped member having a plurality of serrations therein extending generally parallel yto the length of the rail, an elongated spring clip extending through said inverted U-shaped member with one end of said clip bearing against the top of the rail flange and the other end bearing against the top of the tie plate, and a serrated wedge shaped locking key between said clip and the underside of said U-shaped member, the serrations in the locking key being shaped to fit into the first named serrations.

5. A rail fastening device according to claim 4 in which the bottom surface of the locking key is arranged at a steeper angle than the top surface of the flange of the rail.

6. A rail fastening device according to claim 5 in which the distance between the top of the plate and the underside of the wedge is substantially greater than the thickness of the plate.
