BOLTLESS ANTICREEPlING DEVICE FOR RAILROAD RAILS.

Application filed August 2, 1.923. Serial H0. 855,273.

To all whom it may concern Be it known that l, Anonnmnr J. Co K, a citizen of the United States, residing at ester-lo, in the county of Albany, State of New York, have invented certain new and useful Improvements in Boltless Anticreeping Devices for Railroad Rails, of which the following is a specification sufiiciently full, clear, and accurate as to enable those skilled in the art to make and use the same.

The object of the 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 or" therails relative to the ties an der trallic. 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.

The invention consistsin certain novelties of construction and combination of parts as herein set forth and claimed.

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

Figure I is a. view in perspective of a track rail and tie with my improved anti crecping device combined therewith.

Figure 2 is a side elevation of a metallic plate partly fashioned Figure 3' is a perspectivelview partly in section of the locking wedge which with the plate constitutes the entire anti-creeper.

Referring to the several figures, 5 designotes the connnon railroad rail having l'langes'fi, 6 with top inclined surfaces; 7, a common form of tie in practice partly enihcdded in track ballast: i, the vertical sur faceof one side of the tie; 9,.the fashioned plate forming part of the anti-creeper: 10, dotted line. the line on which bent or turned to an inverted l.) shape, as shown by Figure 1: 11, the edge of the plate; 12, two jaws at the edge of the plate and at opposite ends, each jaw having an inclined under surface 14 to match the inclined surface of a rail flange; 15, a metallie locking wedge of a general U shape in, cross section providing a recess or channel to receive the edge 11 of the plate, as show 18, one end of surface at the end of the wedge inside the to serve as an element of the entire device.

. load; the application of the the plate is the wedge; and 17 is a beveled.

channel'to facilitate the movement of the same along the edge 11 of the plate when the wedge is being driven into position. v

To apply the device, first, the plate is slipped over the end of the rail before the same is secured to the ties so the jaws 12 will overlap the flanges 6 of the rail, the beveled surfaces 14 of the jaws matching the top beveled surfaces of the rail flanges, and the side of the plate frictionally engaging a vertical surface Slot a tie; and, secondly, the locking wedge 15 is driven into position along the under surface of the base of the rail and with the edge 11 of the plate seated within the channel in the wedge and frictionally engaging the metal defining the said channel.

As the plate 9 is of spring metal preferably, the insertion of the wedge draws the jaws down upon the flanges of the railand linsures a firm and secure grip. Obviously, jwhen a train passes over the rail, and the jforce thereof tends to move the rail relative -t0 the tie, the grip of the jaws will be increased, inasmuch as the plate bears against 'the vertical snil ace 8 of the tie.

From the foregoing description taken in connection with the drawing it will be that l have devised a holtless anti-creeping- ,device for rails which will perform the requisite function or" holding the rail in place relative to the tie.

The general causes of rail creeping are: the Wave motion of the track under the alternate application and release of a rolling brake, especially when the wheels slide; curvature of the track when the velocity of the train er or less than the velocity for outer rail is elevated; and

A plurality of my devices in use will. an chor the rails to the'ties so they cannot move relative to the ties, and consequently the force or forces which cause creeping must be transmitted to several ties at the same time and at difierent points, thus distributing the energy move relative to the track ballast.

Vl hat I claim is:

1. An anti-creeping device for rails con; sisting of a metallic plate having jaws at one edge and the opposite edge disposed eral lei wi-th'ancl in a plane below the jaws, and a locking wedge adapted to engage the said edge and the base of a rail.

2. An anti ereeping device for rails consisting of a metallic plate having two parallel edges one of the edges being provided with jaws, and a locking wedge fashioned to engage the other edge of the piate and the base of a rail.

3. The subject-matter of claim 2 said iock-' ing Wedge having a channel. to receive the edge of the plate.

4. An anti-creeping device for rails consisting of a plate substantially U-shapcd in cross section one edge only thereof being provided with 'a\\'s, the other edge hein; located below t 1e said jaws, and a wedge adapted to engage the said plate and the base of a rail.

5. An anti-creeping device coneistingofesa-e16 two elements each substantially Jrshaped inelement.

6. The combination with a rail and tie, of an anti-oreeping device comprising two parts one part being of spring metal U shaped in cross section, one edge only having' a single pair of jaws engaging the flanges of a rail and a surface engaging one surface of the tie, and the other part engaging'i'he said first mentioned part and the base of the rail with a wedging aciion which forces the jaws against the flanges of the rail:
