RAIL ANTICREEP AND ANTISPREAD ANCHOR.

Application filed January 28, 1929.

As is well known by those engaged in railroad operation, the general causes of rail creeping are: the wave motion of the traclr under the alternate application and release of a rolling load; the application of the brake, especially when the wheels slide; curvature of the track when the velocity of the train is greater or less than the velocity for Which the outer rail is elevated; and descending grades. Bails creep also excessively on bridges.

The main object of my invention is the provision of a device which when several thereof are combined with track rails and cross ties will prevent the creeping or longitudinal movement of the rails relative to the ties under tallic. Its function is to hold the rail in a fixed position relative to the tie so the force which causes creeping will be transmitted through both the rail and tie to the track ballast.

Another object is the provision of a rail anchor which shall perform the additional function of preventing the sideways movement of the rail relatively to the tie, or the spread of the rails.

The invention consists in certain novelties of construction and in the combination of parts as herein set forth and claimed.

The accompanying drawing illustrates an example of the embodiment of the invention, the parts being constructed and combined according to the best mode of procedure I have so far devised for the purpose.

Figure 1 is a view in perspective of part of a track tie and part of a rail, showing also my improved rail anti-creep and antispread device in position applied to the rail and tie.

Figure 2 is a perspective view of the device as it appears prior to its application to the rail and tie.

Figure 3 is an end view of the lower part of Figure 1, showing the rail in section and the device in side elevation.

Referring to the figures, the numeral 5 designates a track tie of the usual type; 6, the rail head; 7, the web of the rail; 8, 8 are the base flanges, and 9, 9 the usual spikes which secure the rail to the tie.

The de ice consists of a blank of metal, shown by bigure 2, preferably of soft steel or malleable iron, bent or fashioned to the shape shown by Figures 1 and 3. i

The jaw 15 is integral with the shank 10.

Serial No. 335,721.

lit the end opposite the jaw 15 is an up wardly projecting lug 11 with two seats for one flange of the base of the rail.

The auxiliary jaw 1% is formed by bending the metal back of jaw 15 at 12 upon itself through an arc of about 180 to a curved shape and substantially parallel with the jaw 15 so the end of the jaw 1d will pref erably engage the side surface of the jaw 15.

Cllhe strap end 1'? has a hole 18 at the end to receive an anchoring spilre 19. This strap is first bent on the line 16 to a vertical position at right angles to the length of the shank 1.0 o.. the blank, and then bent on the line 90 right angles to the vertical plane of the shank so that, when the device is applied edgewise beneath the flanges of the rail and in frictional contact with one vertical surface of the tie, the under surface of the strap will lap over and frictionally engage the top surface of the edge of the tie, as shown.

Figures 1 and 3 illustrate the device applied to the rail and tie, the same being forced to'its proper position and the strap secured to the top surface of the tie by the spike 19.

The edge of one of the flanges of the rail will engage one or the other of the seats on the upwardly projecting lug 11, depending upon the distance the body of the device is forced beneath the rail base.

It will be seen that the free end of the curved auxiliary jaw 14 bears against the side of the main jaw 15 and also upon the top surface of the rail flange, whereby additional strength and increased bearing surface are secured when the anchor is driven. to position.

The auxiliary jaw as the lower edge is in a plane below the lower oblique edge of jaw 15 not only increases the grip on the flange, but also has a tendency when driven on to tilt the main jaw and produce a twisting gripping effect.

Bending one end of the blank on the lines 16 and 20 brings the strap 17 to a position where it lies flat upon the top surface of the tie. When spiked to the tie the strap holds the anchor against the side of the tie under all conditions of service, and at the same time prevents the side movement of the rail relatively to the tie; or, in other words, prevents the spread of the rails.

From the foregoing it will be clear that l have produced not only an eflicient rail anchor for holding the rail against longitudinal-movement relatively to the tie, but also a device having the additionalfunction of preventing the spread of the rails.

A plurality of my improved devices will in. use anchor the rails. .to the ties solhe rails will not creep, and at the same time they will prevent the displacement of either rail or both rails relatively to the length 01" the ties;;in= other,- words prevent the spreading oft-he rails.
