- RAIL ncnon.

Application filed April 27, 1927. Serial No. 188,867.

This invention relates to devices for pre venting longitudinal creepage of railway rails, and has for one of its objects the pro vision of a rail anchor which shall be of improved construction'and operation, which may be cheaply manufactured, easily ap-.

' plied, and which will effectively grip the rail and prevent longitudinal movement thereof.

Other objects of theinvention will appear from the following description.

The invention is exemplified in the combinationand arrangement of parts shown in the accompanying. drawings and described in thefollowing specification, and it is more particularly pointed out in the appended claims.

In the drawings Fig. 1 is an elevation of a portion of a railway rail having one embodiment of the present invention applied thereto;

Fig. 2 is a vertical section substantially on line 2-2 of Fig. 1; i

Fig. 3- is a viewsimilar to Fig. 1, showing a modified form of the invention; and p Fig. 4 is a section on line 4-4: of Fig. 3.

The numeral 10 designates a railway rail resting upon a tie 11 and supported on a tie plate 12. A yoke 13 is approximately V- shaped to fit over the edge of the base flange oi the rail 10. A clamp 14 engages the outer faces of the yoke 13 to hold the yoke in position on the rail flange. The lower face of the top leg of the yoke 13 is preferably provided with points orprojections 15 for engaging the upper face of the rail flange to insure a firm grip on the flange. Corrugations 16 are formed on contacting tacos oi the upper legs of the yoke 13 and clamp 14% and depressions or notches 1? are preferably provided in the yoke 13 for receiving the arms of the clamp 14. The upper leg of the yoke 13 is preferably slightly tapered in section so that the leg is somewhat thicker at its end than it is near the bent portion of the yoke. The clamp 14L and yoke 13 are partially assembled betore they are sent outto be applied, the clamp being driven sulficiently onto the yoke so that they will be held firmly together. However, the yoke will not be sufficiently compressed by the clamp to prevent the yoke from being placed upon the rail flange. r

in applying the device to a flange, the yoke is first placed over the flange and blows are directed onto the outwardly extending portion or the clamp. This will drive "the yoke home until the flange engages the bent portion of the yoke. l1 urther blows will force the clamp inwardly so that the wedging action. exerted thereby will cause the yoke to firmly grip the rail flange. The yoke isv made very strong and still, but of spring material so that a great force will be exerted upon the yoke, thus gripping the flange with sulticient force to prevent relative slipping ot' the yoke and flange. It will be noted in Fig. 1 that the yoke projects laterally from the clamp 14- and the edge of the yoke bears against the tie plate 12. This -will prevent any movement oi the yoke to the right, as viewed in Fig. 1, and.

conseqnently will hold the rail and tie against relative moven'ient in this direction.

In some cases it' is desirable for therail nchor to enf the tie directly instead of the tie plate. In the form ol the invention shown in Figs. 3 and t the lower leg oi the clamp leis bent downwardly and backwardly, as shown atQO, and forms an abutment surface for engaging the face of the tie 11. The projecting portion'ot' the yo e 13 may be reduced to provide a space shown at 22 between the yoke and tie plate. This will prevent the yoke from exerting pressure directly on thetie plate.

I claim 1. A rail anchor comprising a yoke having arms the inner faces of which are formed to engage opposite "faces of a rail flange, and a clamp formed to engage the outer faces of said yoke for holding said yoke firmly in contact with said flange, said yoke and clamp being connected with one flange only of said rail.

2. A rail anchor comprising a yoke having upper and lower arms engaging opposite taces of a rail flange, and a clamp having resiliently held arms arranged to engage the outer faces of said yoke respectively, the arms of said clamp having relatively inclined contact faces for engaging said yoke so that said arms will produce a wedging action for gripping said yoke when driven into place on said yoke.

3. A rail anchor comprising a yoke having relatively inclined arms for engaging the upper and lower faces of a rail flange respectively, and a clamping device having relatively inclined arms arranged to be driven into place onto said yoke to force the arms of said yoke into gripping engagement with said. rail flange. v

4. A rail anchor comprising a yoke having upper and lower arms for engaging the opposite faces of a rail flange, one of said arms having projections thereon for gripping the surface of said flange, and a spring clamp having relatively inclined arms for engaging the outer surface of said yoke arms when said clamp 1s driven into place on said yoke, said clamp and yoke having interfltting projections and depres clamp in place on plate bent into V-shape to form a yoke for engaging a rail flange, the arms of said yoke having a plurality of transverse depressions on their outer faces, and a spring clamp having inclined arms for engaging said depressions and arranged to be driven onto said yoke to hold said yoke in position on said rail flange.

7. A rail anchor comprising a yoke having arms for engaging opposite faces of a rail flange, one of said arms being tapered to increase in thickness toward the end thereof, and a spring clamp having arms provided with contact faces diverging from each other at a greater angle than the angle between the upper and lower surfaces of the rail flange and arranged to exert a clamping action on said yoke when driven into position thereon.

8. A rail anchor comprising a spring plate bent into V-shape to form a yoke for engaging a'rail flange, the upper leg of said yoke having projections on its lower face and corrugations on its upper face,

both legs of said yoke having depressions on their outer faces, and a spring clamp having arms diverging from each other and arranged to engage the depressions in said yoke, said clamp having corrugations on the upper arm thereof for engaging the corrugations on said yoke to hold said clamp in position on said yoke.

9. A rail anchor comprising a yoke having relatively inclined legs for engaging the opposite faces of a rail flange, and a spring clamp having arms for engaging said yoke, said arms having an initial position for gripping said yoke when said yoke is partially inserted into said clamp, the arms being arranged to yield to permit further engagement between said yoke andclamp when said clamp is driven onto said yoke.

10. A rail anchor comprising a yoke for engaging a rail flange, and a clamp arranged to engage said yoke to hold said yoke in position on said flange, said yoke having a projecting portion for engaging a tie plate to hold said clamp out of contact with the tie on which said plate rests.

11. A rail anchor comprising a spring clip for engaging a rail flange, and spring clamping jaws embracing said clip to hold the same in position on said flange, said clip and jaws being formed to be positioned and held on only one flange of the rail.

12. A rail anchor comprising a spring clip for engaging a rail flange, and spring clamping jaws embracing said clip to hold the same in position on said flange, the thickness of said clip being less than the space between the rail flange'and the tie when the rail is supported upon the tie with anintervening tie plate and the thickness of the spring clamping jaws being greater than said space between the rail flange and the tie so as to extend one of said clamping jaws below the top of the tie.

in testimony whereof I have signed my name to this specification on this th day of April, A. D. 1927.
