Application filed December 1, 1924. Serial No. 753,200.

To all whom it may concern:

Be it known that I, ADONIRAM J. C0011, a citizen of the United States, residing at VVesterlo, in the county of Albany and State of New York, have invented certain new and useful Improvements in Boltless Rail Anchors; and I 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.

As is wellknown by those engaged in railroad operation, the general causes of rail creeping are: the Wave motion of the track 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. Rails creep also excessively on bridges.

The 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 trafiic. 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 of the device itself'and also in its combination with a rail and tie as herein set forth.

Figure 1" is a view in perspective of my improved boltless rail anchor combined with a rail and tie as it appears when in use.

Figure 2 is a view in perspective of the fashioned metallic plate constituting part of the anchoring device. I

Figure 8 is a sideview in elevation of the plate as cut to shape.

Figure 4: is a View in perspective of the wedge; T

The numeral 5 designates the head of a track rail; 6,-thebase flange; and 7 a tie of well-known construction.

The anchor consists of two parts, a metallic plate and a wedge.

The plate 8 is fashioned so as to have the lug or jaw 9 with a recess '10 beneath, a lug or jaw 11 with a recess 12 beneath, and a plain edge 14:. A spring tongue also is desirable designated by 13. The tongue is formed by cutting the metal downwardly and horizontally beneath the lug or jaw 11 and then bending the metal to a position at right angles to the face of the plate as clearly shown. The wedge 15 is fashioned so as to have a longitudinalgroove 16, a plurality of notches 17 and a head 18, as shown by Figure 4. I

The plate is passed over the end of the ra l and to a position adjacent the vertical surface of a tie, the same being disposed obliquely to the length of the rail. The

wvedge is placed with its head bearing against the vertical surface of the tie and overlapping the flange 6 of the rail,t-hat is, the edge of the flange is seated within groove 16 of the wedge. The edge of the plate having the spring tongue 13 is then forced over the end of the wedge until the tongue engages one of the notches in the wedge which locks the plate to the wedge.

It will be observed that the plate is still slightly. disposed at an angle to the length ofthe rail or diagonally thereto so that any 50 I longitudinal strain or motion imparted to the rail by the train passing over it has a tendency to tighten the grip of the anchor upon the rail by forcing one end of the plate longitudinally of the wedge'and the jaws 9, 11 down upon the flanges.

From the foregoing description taken in connection with the drawing it will be clear that I have devised a boltless anti-creeping device for rails which will perform the requisite function of holding the rail in place relative to the tie.

A plurality of the devices illustrated will in use anchor 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 different points,

thus distributing the energy so the rails and ties will not move relative to the track ballast. I

What I claim is: Y l An anti-creeping device for rails consisting of a metallic'plate and a wedge, said plate having lugs or jaws at the ends, a seat for a wedge, said seat formed by cutting the metal of the plate and bending outwardly the metal between the cuts, and an edge to engage the under surface of a rail, and said wedge having a A by the metal of the plate which is bent outendly- 5 *2? An anti-creepinggdevice. for rails censisting of a metallidplat' and awedge, said plate having rail engaging lugs en j ayy s at the endg, a Seatfpl: a Wedge, and a, tongue,

iesiei w dg ha g iee o f t the edge of the flange of a rail, a head, and a 1 notgch adapted, to be engaged by the said In'testimony whereof I affix my signature.

ADONIRAM J. COOK.
