BAIL ANCHOR.

Application filed April as, 1925. Serial No. 25,374.

To all whom it may concern:

Be it known that I, JUNIUs E. BUsnY, a citizen of the United States, residing at Jackson, in the county of Breathitt and State of Kentucky, have invented certain new and useful Improvements in Rail Anchors, of which the following is a specification, reference being had to the accompanyling drawings.

T is invention relates to anchors for preventing railroad rails from creeping, the general object being to provide a device of this character which is adapted to be resiliently clamped upon the base of the rail and which will engage with a tie to'prevent any creieping or longitudinal movement of the m1 One of the objects of the invention is to provide an'anchor of this character which may be applied to the rail by simply driving it onto the flange from one side and which will spring into place after being driven and which may be as readily detached from enga ement with the rail.

3 further object is to provide an anchor which cannot be put on wrongly, which cannot be over-driven, and which does not reqpfireany special tool to put it on or take it o A still further object is to provide an 3.11

chor having a spring coil of such character as to give it very great gripping power so that the anchor will not jar or work oif the rail, and furthermore a coil which will not Weaken in its resilience. o

Another object is to provide an anchor of this character having a coil which will rest centrally on the base ofthe rail and extend down low enough to secure plenty of bearing against the side of the tie to thereby insure a positive stop against creeping and which is so formed that the anchor w1ll not slip .forward on a tie that might have a rounded edge.

My invention is illustrated in the accompanying drawing, wherein Figure 1 is a perspective view of a rail anchor constructed in accordance with my invention;

Figure 2 is a sectional view throu h a rail showing the anchor in applied position;

.Figure 3 is a top plan view of the rail partilydbroken away and showing the anchor ap 1e eferring to the drawing,it will be seen that my improved anchor consists of a sin le piece of spring steel preferably rectangu ar in cross section. At one end the spring steel is bent to form an .upwardl extending abutmerit 10. The piece of stee is then extended at a gradual and slight angle and then formed to provide the coil 11 and beyond the coil 11 the material is extended in substantially a straight line, as at 12, then curved upward, as at 13, then inward w1th a slight upward curvature, as at 14, and then is angularly bent parallel to the axis of the coil and above the coil, as at 15. It wlll be noted that the material from which this anchor is made is twisted so that what is the side face 16 of part 14 is gradually deflected so that it forms thelower face 17 between the coil and the portion 10. This portion 10 extends upward just the height 0 of a rail flange.

The anchor is applied to the base of the rail by disposing the part 15 over the upper face of one flange of the-rail with the portion 12 beneath the base of the rail and then driving transversely of the rail on the part 13 until the abutment 10 snaps up in front the edge of the opposite flange of the rail. Under these circumstances the rtion 15 lies flat against the rail and t e portion 16 fits tightly oven the upperface of the flange,

while the remainder of the anchor fits beneath the flange. The anchor can'then be removed from the rail by striking a downward blow on the upper end of portion 10, causing this to slip beneath the flan e, whereupon the contractile resilience of t e coil will draw the *part 10 inward beneath the flange and the anchor can be very easily knocked off.

The coil portion 11 of the anchor is designed to cover enough space on the side of thetie as to insure a positive stop and and inward to fit over the top will not slip on a tie that has a rounded edge, as many rail anchors will do It will be seen that in my anchor the loop or coil 11 is complete. This gives it a good gripping power and has a springing action which will not become loose. Most onepiece rail anchors when once driven on and then taken off never hold tightly thereafter. My closed coil secures a good holding power at all times. It will be seen that this anchor cannot be overdriven for the reason that the portion 15 will stop the anchor as soon as this portion 15 strikes the web of the rail. The portion 15 disposed angularly to the portion 16 is made long enough so that when the rail begins to creep this part of the anchor will exert a downward pressure and as a consequence will grip upon the rail much tighter. By reason of the fact that the part 10 does not extend above the rail, the anchor can be used on tracks where curved guard rails are necessary, as the anchor will not come in contact with the guard rail.

I claim 1. A rail anchor formed of a single piece of resilient material, the material being formed to provide a medially disposed coil, the ends of the coil crossing each other, one end of he material being upwardly extended to form an abutment adapted to rest against the edge of the rail base, the other end of the material being formed to fit beneath the rail base and then bent upward of the rail base and then angularly extended longitudinally of the rail.

2. A rail anchor comprising a single piece of resilient material bent to form a coil, the ends of which cross each other, one end of the material being formed to extend beneath the base flange of the rail and then extended upward, the other end of the material being bent to extend in an opposite direction beneath the rail flange and then bent upon itself and extended inward to conform to the upper face of the rail flange and then being bent to extend longitudinally of the rail to form a portion adapted to bear against the web of the rail, the material being twisted in its length.

3. A rail anchor formed of a single piece of resilient material, the ends of the material being formed to engage with the rail, the intermediate portion of the material being formed to provide a closed depending coil.

4. A rail anchor formed of a single piece of resilient material bent to form a coil adapted to be disposed beneath a rail, a portion engaging beneath the rail base and over the top of the rail base, the opposite end of the material being upwardly extended a distance equal to the thickness of the rail base at its edge whereby to permit-the anchor to be used on tracks where curved guard rails are used,

5. A rail anchor of the character described formed of a length of material rectangular in cross section and bent to provide a medial tensioning member, a portion extending from the medial tensioning member and adapted to engage one edge of the rail base, and a portion extending in the opposite direction from the tensioning member and formed to extend over the rail base and over the upper face thereof and then being extended at right angles to the plane in which the anchoring device is disposed to engage along the web of the rail, the piece of material being twisted in its length.

In testimony whereof I hereunto aflix my signature.
