To whom it may concern.

Be it known that I, Anoxnsur J. CooK, a citizen of the United States, residing at \Vesterlo, in the county of Albany and State 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, es ecially when the wheels slide; curvature 0 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 general 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 traffic. ts 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.

lhe specific object is the provision of such a device which shall be simple in construction-in a single piece-chea )ly produced, and easily applied, and which s iall be adapted to perform the requisite function.

The invention consists in certain novelties of construction as herein described and specified in the claims.

The accompanying drawing illustrates an example of the practical application of the invention, the device being constructed according to the best mode of procedure I have so far devised for the p rpose.

Figure 1 is a view in perspective-of the rail anchor and a rail and a tie with which the rail anchor is combined or associated.

Figure 2 is a view of the anchor as fashioned prior to the banding thereof.

Figure 3 is a perspective view of the bent or completely fashioned anchor.

The anchor consists of a plate of soft steel or malleable metal cut and fashioned to the shape shown by Figure and then bent upon itself on he dotted hue 16, oblique to the length of the plate, and to the shape shown by Figure 3.

The number 5 designates a tie of well known form: 6, a flanged track rai and 7 the flange of the rail.

The part 8 of the plate is located beneath the base of the fail, the top edge being in frictional contact with the under surface of the rail base. and the projecting lug 15 cngages the edge of one of the flanges of the rail. as shown in Figure 1/ The number 17 designates a vertical offset in the bodv of the metal; 9. the end of the plate bent through an arc of 180 upon the line 16 diagonal to the length of the plate; 10.,a jaw; 11, an offset in the metal of the jaw; 12, a jaw; 13, a slot beneath the jaw 10, as shown; anal 1% is a slot beneath the jaw 12 to receive the flange of the rail.

It will be noted that the offset 11 in the jaw 10 and the offset 17 in the part 8 of the plate extend in opposite directions, and that the offset 1? allows the part 8 to clongate slightly when the anchor is forced into position and thus serves as a spring to cause the projection 15 to grip the edge of the rail flange under all conditions. The offset 11 increases the area of the hearing surface upon. the top surface of the said flange.

As shown by Figure 3, the bending of part 9 ()l. the diagonal line 16 causes the jaw 12 to project above the jaw 10 and the top edge of hcnt 9, below the jaw 10, to lie in a plane oblique lo the straight top edge or" the part of the plate Obviously, when the anchor is forcibly applied to the flange of the rail the parts frictionally gripping the surfaces of t 1e flange will be under spring tension, as the metal will be in a degree distorted from its relative normal position. The grip of the anchor when driven into position gives what may be termed a twisting grip upon the rail flange.

Further, the weight of the train when passing over the rail causes an increase of the gripping action, inasmuch as the anchor is pressed against the tie.

From the foregoing description it is clear that I have provided a one-piece rail anchor which is cheap in iirst cost, simple in construction, and efficient in operation when applied in connection with a rail and 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 conse quently the force or forces which cause ing two substantially parallel parts 8 and 9,

one part 8 adapted to frictionally engage the under surface of a track rail and pro ill vided with a projection, and the other part 9 provided with a slot 'to receive a flange of the rail. the line 16 joining the two said parts being oblique to the longitudinal axis of part 8, whereby the part 9 extends at an oblique angle to the longitudinal axis of said pm 8 and the slot in said part 9 is similarly disposed.

2. The subject-1natter of claim 1 wherein the part having the projection is provided no with an offset 17, as set forth.

3. A metallic rail anchor made of a single piece of metal bent upon itself on the oblique line 16 and provided with a projection at one end and two jaws at the opposite end, the surfaces of said jaws for engaging the flange of a rail being in planes oblique to each other due to the bending of the metal on the raid oblique line.

4. The subject-matter of claim 3 wherein one of the said jaws is provided with an offset 11. as set forth.

A rail anchor of resilient metal having a projection at one end and two jaws at the opposite end, the metal being bent upon itself on an oblique line to bring the jaws into parallel planes with the gripping edges of the jaws disposed in oblique lilies.

In i8Stlm()ll whereof I aflix my signature.
