RAIL-ANCHOR Patented July 9, 1912.

Application filed March'1-4, 1912. Serial No. 688,652.

To all whom it may concern:

Be it known that we, JOHN W. STEPHEN- SON and DAVID C. STEPHENSON, of Toledo,

anchor; and Fig. 4 is a perspective of the key member shown in Figs. 1, 2 and 3.

Our invention relates to rail anchors and is designed to provide a simple, effective and positive means foranchoring the rail and to prevent it from creeping. The rail anchors or anti-creeping devices which have heretofore been provided for this purpose have not proven satisfactory in use for the" reason that they work loose and become ineffective in service, or are so complicated that they cannot be correctly or readily applied to the rails bythe ordinary track laborer. For efficient service it is of the greatest importance that a device of this character should be positive in its action, and, should be secured to the rail withoutthe possibility of' its working loose from either the rail or the stationary element with which it cotiperates to prevent movement; The anchor-should also be of such character that, it can readily and easily be applied to the rail by unskilled workmen. Such atde'vice is' pr ovided by our invention. Referring to the drawings, 2 designates a portion of the track rail; 3, 3 are the rail flanges; and 4: is the tie. J v

5 isthe anchor having the projection 6 adapted for engagement with the flange 3' of the rail 2, and having depending webs 7 which lie below the rail base and are adapted to be attached to the tie 4 by the bolts,

or similar fastening means, 8. At the side opposite the projection 6, the anchor 5 has an upwardly extending member 9 which has under-cut bearing surfaces 1G, the base of which is inclined longitudinally and vertically with respect to the rail, and which, with the rail flange 3, form guidewaysll for the keys 12. The guideways 11 have restricted curved portions 13. The keys 12 are of wrought metal capable of bending and have a driving heel 14 and'av lip "15 for engagement with the rail flange.

Afterthe anchor 5 has been placed in position and fastened to the tie 4 by the bolts 8, and with the rail flange 3 under the lip of the projection 6, the keys 12 are inserted and driven into the guideways 11, the inner end portions 16 of the keys 12 striking thecurved wall 17 of the guideway portions 13, and are deflected therefrom laterally and outwardly, as is shown in Fig. 1. The keys 12 have inclined bearing faces 18 which coact with the bearing faces 10, which forces the 'lips'1 5 and the vertical face'19 on the oppositefaces of the keys to grasp firmly the rail flange 3. The bending and deflection of the keys 12 in the curved portion of the guideways 11 forms a secureand clenching engagement which will prevent the key from working loose, so that the key will hold the anchor securely to the rail and revent therail from creeping by reason 0 the anchor 5- being firmly'secured to the tie 4. It'willbe' seen that when the keys 12 are inserted and'driven home, in themanner described, that they form secure and positive fastenings which cannot work loose, and the initial and proper application of the keys 1s secured, since the laborer has only to in-- sort the keys and drive them .in as far as they will-"go. If it becomes necessary atany time to remove the rail, this can be done by sledging the abutments 20, which are located on. the upper surface of the keys 12, in the opposite direction from that in which thekey was driven when originally inserted.

This will force the bent ends ofthe keys.

out of the curved guideways and release the binding engagement of the anchor to the rail.

While we have shown'arail anchor havingtwo bendable members, it is obvious that an efiicient anchor can be obtained whereionly one bendable key member is provided.

Other changes may be made in our im proved anchor without departing from our invention, since What we claim is:

1. A track anchor for rails, comprised of plates and a connecting web member for en agement of a tie, said plates and said We% member having means for securing to said tie, said plates having upwardly elf!- tending projections, one of which projections is adapted to engage a flange of the rail, and the other of Whichhas an undercut face inclined longitudinally of, the rail 2. A track anchor for rails,, coniprised of plates for engagement of the tie, one of said plates having a projection to engage a flange of the rail, and the other side of the plate having an upwardly extending memher, a guideway between said upwardly extending member and the .other flange of the rail, and, a bendable key adapted to be driven into said guideway to secure said anchor to said rail, and a vertically dis- Oopi's of this patent may be obtaineifor posed Web member connecting said plates adapted to be secured to the tie. I

3. A track anchor for rails, comprised of asaddle for engagement of the tie, projections from said saddle, one of the projections from said saddle being adapted to engage a flange of the rail, another of said projections forming With the otherv flangev of the rail a guideway, and a bendable key member adapted to be driven into said guideway to secure said saddle to. said'rail.
