Jan. 21, 1930. L. R. PARSONS RAIL ANCHOR Filed April 9, 1929 Patented Jan. 21, 1930 UNITED S ATE- LOUIS R. PARSONS, or s'rnonenunsr, rumors A L ea e npplication filed April 9,

This invention relates to an improvement in rail anchors, in the use of which the rail is anchored with respect to the'tie against longi tudinal Creeping. A ii The invention coinprehends a unitary or integralstructurewhich may be re adily connected to or disconnectedfrom the rail, and which when in place will have such relation to the rail and tie that any creeping tendency 0 in the rail will act to compel tin-increased wedging cooperation between the rail anchor andtheraih to thereby additionally resist a y e r tend nc i t 're Th P ma y o j of th P e ent in e tion is the provision of a rail anchor which, as a result of its construction, is, when applied, disposed in wedging cooperation with the rail supplemented'bya clamping action designed to inherently increase the wedging ene t on t there y inse s the bs u e fixing of the ancho s il d in the direction of rail creeping. i '1 i A further object of the present invention is the provision of a wedging column which extends from the clampingjaw portion of the anchor to underlie and engagethe tread of the rail, with such wedg ing column atall times at an inclination to the'vertical plane of the clamp portion of the anchor, so'that when theanchor driven to place, the wedging column has a wedging relation with the ball or tread of the rail, incident to and a direct result of applying the g rnchor.

The invention illustrated in the accompanying drawings, which t Figure l is a {View showing the rail in transverse'isection and the anchor in fronteleva tion. v I v Figure 2 a side view of thesame.

The improved rail anchor, which is preferably constructed of round highlte'nipered steel ofappropriate diameterfcomprises a 2 Se l a 1 w?- t'ie engaging bar 1 adapted to underlie the rail, and centrally formed with a rounded depending offset 2. The bar l is terminally formed at one end with a hook 3, designed to engage with and beyond one edge 4: of the base flange 5 of an ordinary rail 6, the rail of course including the web 7 and ball or tread portion 8.

The rail engaging bar 1, at the end opposite the hook 3, is formed in'a return bend to provide what may be termed a clamp having upperand lower jaws 9 and 10. These jaws are normally spaced apart to permit the passage of the edge of the base flange 5 between them, the clamping space between the jaws being restricted at the inner end, as at 11, to insure a cla-mping'engagement with the upper and lower surfaces of the base flange. This clamping space is, outwardly of the restricted Por o 3 at 12.

The upper 9 of the clamp of the anchor is ektended'upwardly as a wedging column 13. This wedging column is of a length e;- ceeding the distance. between the upper jaw 9 of thdclamp and the bottomof the ball or tread. portion 8 of the rail. The column inclines inwardly from the end of the clamp jaw 9 toward the web of the rail, and also inclines from theend of the'clamp jaw 9 at an angle to the'verti'cal planepas sing through the clamp and bar 1.

Thus, the rail anchor includes the bar 1 and clamp whicharedisposed in the same vertical pianae a the wedging column which risen-om the clamp at a dis tinctangle to this vertical plane. It is understood that the anchor is asubstantially rigid structure, and that it" is normally constructed with the wed ging column atthe angle described. 'Thus,in applying the rail anchor, the wedging column is normally in"'we' -1ging cooperation "with the ballortread of't h'c'rail. i L

' In the application ofthe anchor, the clamp engaged with" one edge of the base flange oftherail, with the bar l'underlyingthebase flange ofthe'railandthe hook 3 immediately adjacent that edge of the base flange remote from the clamp. Inthis positionfthewedggradually enlarged, as indicated h ingcolumn rises from theclanip at an angle to the vertical and underlies the outer portion of the ball or tread of the rail. The anchor is then driven into place, until finally the hook 3 engages the edge of the base flange of the rail. During this movement, the wedging column has been driven into wedging cooperation with the ball of the rail, and incident to the fact that the wedging column is inclined from the vertical, the wedging action of the upper end of the column with the ball of the rail tends to slightly turn the clamp from its vertical plane, as indicated clearly in Figure 2. There is of course, under this slight distortion of the clamp, an inherent tendency in the jaws of the clamp to return to the normal position that is to a position in which the clamp proper is in a vertical plane. This inherent tendency obviously tends to move the free end of the wedging column in a more effective wedging cooperation with the tread of the rail. As the wedging action of the column cannot be increased by this tendency of the clamp. it is apparent that the inherent tendency of the clamp tends to efiec tively maintain the wedging cooperation of the column, while the wedging cooperation of the column tends to maintain the slight distortionot' the clamp. The wedging action and clamping action are thus more effectively maintained as a direct result of the application of the anchor, and without other operations than the mere application of the anchor.

[The upper or free end of the wedging column, while slightly rounded and properly finished for smooth cooperation with the surface of the tread of the rail, is inclined with respect to a vertical plane passing through the column, such inclination being indicated at 14 in Figure 4, and being in the direction of wedging movement of the column. This insures effective surface bearing between the end of the column and the ball of the rail, and further prevents any possibility of the wedging column ever assuming a vertical position.

The characteristic and important feature of the present rail anchor is the provision of a wedging column which is normally at an inclination to the vertical plane passing through the rail bar and clamp of the anchor.

his inclination of the wedging column insures awedging cooperation between said column and the ballot the rail as a direct result of the ordinary and usual application of the anchor. That is to say, with the anchorapplied in the usual manner, the wedging cooperation of the column and the slight distortion of the clamping action, result as a direct incident to the application of the anchor, and without requiring any further driving actions, applications of force, or operations on the anchor. The mere driving of the anchor to placesecures the full result.

Of course it is understood that the anchor is applied adjacent the side of a tie, as indicated at 15, with the wedging action of the column arranged to resist creeping of the rail.

It is to be particularly emphasized that a salient and underlying feature of importance of the present anchor is that its wedging column is inclined to the vertical plane of the anchor in the normal relation of the anchor parts. That is to say, the extreme upper end of the wedging column is materially offset from the plane of the remaining anchor parts, so that the wedging column is in wedging position as a direct result of and during the application of the anchor.

lVhat is claimed to be new is:

1. A rail anchoradapted for clamping cooperation with the base flange of a rail and having a portion to bear against the supporting tie, said rail anchorincluding a wedging column normally at an inclination to the plane of the anchor.

2. A rail anchor including a tie engaging bar, a rail engaging clamp at one end thereof, and a wedging column extending upwardly from the clamp and inclined to a plane of the clamp.

3. A rail anchor having a tie engaging bar, a rail flange engaging hook at one end thereof, a rail flange engaging clamp at the opposite-end thereof, and a wedging column rising from the clamp and normally at an inclination to the plane of the anchor.

4. A rail anchor having a bar to underlie the rail, a clamp to engage one edge of the base flange of the rail, and a wedging column normally inclined to the plane of the anchor and designed for wedging cooperation with the ball of the rail in the application of the anchor, the wedging cooperation of the column and rail ball corespondingly distorting the clamp to cause the inherent clamping pressure to increase the wedging engagement of the column with the ball of the rail.

5. A rail anchor having means whereby the anchor may be secured to the rail, and a wedging column having its free terminal oflset from the plane of the anchor, whereby to provide an inclined wedging column having a normal wedging position.

6. A rail anchor including means for connecting the anchor to the rail, and including a wedging column inclined with respect to the plane of the anchor proper and also inclined with respect to a vertical plane transverse the anchor proper, whereby in normal position the wedging column is normally inclined in two directions.

7. A rail anchor including means for con necting the anchor to the rail and a wedging column forming part of one of said means and normally inclined with respect to the plane of the anchor, said wedging column in the application ofthe anchor increasing the holding efiect of the rail engaging means of the anchor.

8. A rail anchor having means to removably engage the base flange of a rail and including a Wedglng column rising from the anchor proper at an inclination to the plane of the anchor, said Wedging column providing a rigid non-yielding member normally in Wedging relation to the rail in and during the application of the anchor.

9. A rail anchor constructed of metal substantially circular in cross section and of uniform diameter throughout, said anchor including a clamp to engage one edge of the base flange of a rail, a bar to underlie the base flange of the rail, a hook to engage the opposite edge of the base flange of the rail, and a Wedging column rising from one arm of the clamp at an angle to the plane of the anchor.
