RAIL ANCHOR.

Application filed February 18, 1929. Serial No. 340,747.

The invention relates to rail anchors or anticreepers and seeks to provide a simple and effective construction which can be economically manufactured, and which comprises a clip for gripping one of the rail base flanges and resilient spring means for bolding the clip in position on the rail.

The invention consists in the features of improvement hereinafter set forth, illustrated in preferred form in the accompanying drawing and more particularly pointed out in g the appended claims.

In the drawing:

Figs. 1, 2 and 3 are sectional elevation, plan and end veiws respectively, of the improved anchor.

The drawing shows a rail base 10, a tie 11, and a tie plate 12. The anchor clip is preferably formed of a piece of plate steel or like metal of about one-quarter inch in thickness and which is bent to a U-section to' provide spaced side portions 13 and a bent connecting edge portion 14. The edge portion 14 and parts of the side portions 13 are cut away to provide notches or seats 15 which fit one of the base flanges of the rail for which the anchor is designed. The notches or seats are so disposed that the clip is adapted to be driven from one side of the rail into gripping engagement with one of the rail base flanges and when in position on the rail the side portions 13 are disposed in substantially vertical planes with the intermediate connecting portion 14 extending between their inner ver- 0 tical edges. Preferably, asshown', the seats 15 are so shaped that the edges thereof bear on the upper and lower faces of the base flange of the rail but do not contact "with the edge of the rail flange.

The side portions 13 of the clip extend well below the rail base and are preferably flared so that the lower portions 16 thereof, which form tie-engaging abutments, are so disposed that when one of them is in engagement with a tie 1 1 as shown in Fig. 3, parts of theanchor are held spaced away from the tie-plate 1'2.

The clip has a hard driving fit on one of the rail base flanges and is held against displacement thereon by a part arranged to engage or hook over the other base flange and interposed spring. Preferably these parts are in the form of a cross-arm 17 and a C-shaped spring loop 18. The cross-arm 17 is preferably U-shape'd or channel-shaped in cross section having side walls 19 and a bottom wall 20. At one end, the side walls 19 terminate in ofl'sets or hooks 21 which are arranged to engage the edge of the rail base flange and which preferably are provided with lips 22 which lap or hook over the edge of the rail flange. The cross-arm extends through an opening 23 formed in the inner edge portion 14 of the clip and between the-side walls 13 thereof. At or adjacent its end the cross-arm is providedwith an abutment 24 which engages the outer portion of the spring loop 18. and the bottom wall 20 of the cross-arm is cut away to form a slot or opening 25 through which the lower portion of the spring loop extends. The cross-arm can be conveniently formed .of a section of plate metal, and in .such case, portions of the side walls can be bent inwardly and transversely to form the integral transverse abutment 24, as indicated in Fig. 2.

The spring loop 18 is preferably formed of resilient steel rod of circular section, is shaped to extend around the edge of the rail flange engaged by the clip and has down and upturned inner end portions 26 and 27 which are adapted to bear respectively, upon the upper and lower faces of the base flange. The spring loop is disposed between the side portions 13 of the clip and its lower portion extends between the side walls 19 of the crossarm.

. In the application of the anchor, the spring loop is strained or distorted so that its end portions 26 and 27 are forced apart and in consequence resiliently grip the base flange of the rail. Also, the parts are so proportioned that the spring loop is laterally compressed by the engagement of its end portion 26 with the inner edge wall 14 of the clip and the engagement of its outer portion with the abutment 24 of the cross-arm. Hence, the spring loop serves to press resiliently against the clip and cross-arm and maintain the same in engagement with the opposite rail base flanges. In applying the anchor, the clip and sprin loop are driven onto one of the rail base anges by the application of hammer blows to the adjacent end of the cross- V arm 17. It is noted that the abutment 24 of the cross-arm and the section of the spring loop engaged thereby, are inclined in such a manner that, as the anchor is driven onto the rail base, the' pressure of the spring tends to force the adjacent end of the cross-arm downwardly and thus press its opposite end upwardly. Hence, when the other hooked end of the arm clears the opposite base flange, it will snap upwardly into engagement therewith.

The improved anchor is inexpensive to manufacture and can be readily applied to the rail. Obviously, any tendency of the rail to creep will force the lower portion of the clip against the tie and tend to cant it in a vertical plane extending longitudinally of the rail and will thereby increase its grip upon the rail base flange. 'The spring loop and cross-arm will effectually prevent the clip from working loose when the clip is rubbed against the cross tie or drawn backthrough the ballast by contraction of the rail. To maintain the side sections 13 of the clip in spaced relation and connect the cross-arm and spring loop thereto to form a unitary structure when the anchor is ofl' the rail, spacing rivets 28 extend between these side sections through the spring loop 18 and above and below the cross-arm 17. The slot or opening 25 in the cross-arm is of such length that there is a clearance between its inner edge and the adjacent end portion 27 of the spring loop, so that the anchor is adapted to be dri n into griping engagement with be applied to rail bases of diflierent widths.

Changes may be made in the details set forth without departure from the scope of the appended claims.

Iclaim as my invention:

1. A rail anchor comprisin a clip and a retaining spring, both adapted to grip one of the rail base flanges, and means arranged to engage the other base flange and hold said spring in position.

2. A rail anchor comprising a clip and a retaining spring, both adapted to grip one of the rail base flanges, and a cross-arm having an oflset adapted to be held in engagement with the edge of the other base flange by the spring.

3. A rail anchor comprising a clip and a retaining spring loop for the clip, both adapted to grip one of the rail base flanges with an inner portion of the spring loop engaging the clip, and a cross-arm having abutments at its ends for engaging the outer portion of said s ring loop and the edge of the other base fl zinge respectively. p

4. A rail anchorcomprising a clip and a retaining spring loop for the clip, both adapted to grip one of the rail base flanges with an inner portion of the spring loop engaging the clip, and a cross-arm having abutments at its ends for engaging the outer portion of said spring loop and the edge of the other base 6. A rail anchor comprising a clip of U-.

section for gripping one of the rail base flanges with its side portions verticallydisposed and its bent connecting portion at its inner edge, a C-shaped spring loop disposed between the side portions of said clip and arranged to-resiliently grip the same base flange and engage the inner edge portion of the clip, and a cross-arm having a hook at one end for engaging the other base flange, the opposite end of said cross-arm extending through an opening in the inner edge por tion of the clip and having an opening or slot through which the spring loop extends.
