RAIL-ANCHOR.

Specification of Letters Patent.

Patented Jan. 1, 1918.

Appucation mea september 19, 191s. serial No. 120,918.

Toledo, Lucas county, Ohio, have invented new and useful Improvements in Rail-Anchors, lof which thefollowing is a specification, reference being had tothe accompanying drawings, in which- `igure 1 is an elevation showing my 1mproved anchor applied to a rail and illustrating the rail in section; Fig. 2 is a plan thereof; Fig. 3 is an elevation of the wedge; Fig. 4 is a partial elevation similar Ito that of Fig. 1 but showing a 'modification of the wedge; Fig. 5 is an elevation 0f a vmodied form of my device; Fig. 6 is a plan thereof; Fig. 7 is an elevation of the wedge, and Fig. 8 is a partial elevation, similar` to Fig. 4 githa wedge of the character shown in My invention relates to rail anchors and consists in a base plate and wedge construct- -ed and arranged so as to prevent the rail from creeping. y y

Referring to the drawings,.A indicates a rail section, B a base plate and C the wedge. The plate B has a rall-base engagin jaw 2 and a wedge engaging jaw 3, and a epending foot or abutment 4 intended for engagement with a tie (not shown). Underlying the edge of the rail-basel on the side engaged by the wedge is a depression 5 in the plate B.

The wedge C consists of av jaw 6" which engages the up er and under faces of .a

ange of the rail A and in a wedging facer 7, inclined both to the longitudinal' axis of the rail and to a horizontal plane, 'and engages the correspondingly-inclined c inner face 8 of the jaw 3 on the base-plate B. The outer end of the wedge is provided with an abutment 9 by which it is driven into; place and with a lug 10 on its inner end by which the wedge may be driven out in disengaging.

the fastener from the rail. The lower portion 11 of the jaw 6 extends under the rail ange in the depression 5 of the base plate B. The faces of the jaws 2 and 6 which engage the rail flanges do not diverge as sharply as the faces of the ra'il which they grip so that as the wedge is driven into position the two jaws will be forced slightly apart and thus exert a tight springing grip upon the rail base.

In applying the fastener to the rail the plate B is first placed in position with its jaw 2 engaging one of thebase flanges of the rail. Thewedge C is then driven in and as its inclined side 7 engages the corresponding. inclined face 8 on the jaw 3 it is wedged against one rail flange and draws.

the plate B and the jaw 2 against the other rail Harige.' At the same time the movement of the wedge C, because of the inclination of the faces 7 and 8, forces' the wedge C down upon the rail base so as to hold the rail base and the'base of the plate B firmly together. The horizontal surface 12 on the plate, however, prevents further downward movement of the wedge C relative to the plate B so that the inward movement of the wedge caused by the surfaces 7 and S'results in a lgorizontal movement thereof toward the rail ase.

As the wedge is driven in, the point 13 of the Jaw 3 receives the maximum horizontal pressure of the wedge and is in horizontal alinement with the edge of the rail so that there 1s no twisting action upon the wedge, and the bending stress imposed by the wedge on the jaw 3 is also reduced to a minimum because the depression 5 in the base permits the application of pressure to the jaw 3 at a point substantially in alinement with the surface 12. To prevent the lower portion 11 of the jaw 6 from striking the tie when the wedge has been driven into applied po' sition, the part is cut oif at 14, as is shown in Fig. 3. 4This is of particular advantage either where the fastener is used-on an undersized rail, or where the anchor has been used to such an extent that the parts have become distorted, and therefore can be driven in farther than is shown in the drawings.AN

Figure 1 shows the wedge G engaging the lateral edge as well as the top'and bottom of the rail base so that its lateralpressure upon the rail base is resisted by a -direct contact with the .edge of the base, as well as by the wedging grip upon top and bottom of the base. In case a direct pressure upon the edge of the base is not desired, thewedge may be constructed as lshownin Fig. 4, which shows the wedge gripping only the top and bottom of the rail base so that its contact with the base is' purely a wedging one. i

n Figs. 5, 6 and 7 I have shown a modi- Y, which the wedge C3 grips only the top and bottom ofthe rail base, so that, as in Fig. 4c, its contact with the base is purely a wedging one.

The terms and. expressions which I have employed are used as terms of description and not of limitation, and I have no intention, in the use of such terms and expressions, of excluding any mechanical equivalents of the features shown and described, or portions thereof, but recognize that various structural modications are possible within the scope of the invention claimed.

What I claim is:

l. In a rail anchor, a base member and a rail engaging member adapted to be driven between one part of the base member and the rail, the rail engaging member havin a jaw engaging upper and lower faces o the -rail base and being held from twisting yby a horizontal face in substantial aline- 'ment with the bottom of the rail.

2. In a rail anchor, a base member and a rail-engaging member adapted to be driven between one part of the base member and the rail, said rail-engaging member comprising a rail-engaging jaw extending within a depression in said base member, and a body portion seated upon a horizon-` tal surface of said base member in substantial alinement with the bottom of the rail.

3. In a rail anchor, a base member having oppositely disposed Jaws, one of said jaws having a face inclined both to the longitudinal axis of the rail and to a horizontal plane, ,a wedge having a corresponding face bearing against the face on Saidyja'w and being adapted to be forced thereby against the face of the rail ange, said jaw also having a horizontal bearing'substantially in horizontal alinement with the bottom of the rail and engaging a corresponding horizontal bearing on'the wedge.
