Specification of Letters Patent.

Patented July 112, 1921.,

Application filed September l, 1919, Serial No. 321,687. Renewed. may 31, 1921. Serial No. e73,773.

To all whom it may concern:

Be it known that l, ltonanors BLAIR, a citizen of the United States of America, and resident of Fort Wayne, inthe county of Allen and State of? Indiana, have invented certain new and useful Improvements in Railway-Rail Anchors, of which the following is a specification.

My invention relates to devices for resisting the tendency of railway rails to move longitudinally, and has for its principal. object to provide an improved one-piece rail anchor device, which will maintain a firm hold on the rail base, which will be inexpensive to manufacture, and which is so constructed as to provide a substantially rigid portion for abutting against one of the cross-ties or other stationary parts of the road-bed, and which may be readlly appl ed to or removed irom a rail without requiring the use of track implements of any spec1al term. v

The invention consists in the provision of a new and improved anchor constructed as hereinafter described and claimed, tor carrying out the above stated objects, and such other objects as will appear from the following description.

The invention is illustrated in a preferred embodiment in the accompanying drawing, wherein- Figure 1 is a plan view of a rail anchor constructed in accordance with my inven tion applied in its operative position to the base portion of a rail.

2 is a view in elevation of the device shown in Fig. 1, the rail to which it is applied being shown in cross section; and

Fig. 3 is a view in perspective otrthe rail anchor.

Like characters of reference desi nate like parts throughout the several figures of the drawing,

. Referring to the drawing, the reference character 1 indicates a railway rail, and 2 one the cross-ties on which the rail is supported, The anchor, designated generally at 3, is made, preferably, of a single piece of metal "formed with a recess adapted to receive the base portion of a rail, and having its ends 4: and 5 bent baclrwardly from the tie 2, to provide spring jaw portions which engage with the opposite edges of the rail base. The body portion i of the anchor, that is, the portion which extends adjacent edge of the rail base.

under the rail base, is formed adjacent one edge of the rail base with a tie-abutting portion or face 9 which abutment bears against one of the vertical faces of the cross-tie 2. The tie-abutting portion is preferably formed by providing the body portion 6 with lntermediate bends 7 and 8, so that the end 4c of the anchor will normally stand a short distance away from the face of the tie. It will be seen, also, that the intermediate bends 7 and 8, in addition to forming an offset in the body portion whereby one end is held out of contact with the adjacent tie, provides a portion which is yieldable transversely of the rail base, and is adapted to be stra ghtened during the application of the device to a rail, so as to permit the jaw end 5 of the anchor to clear the edge of the rail. When the intermediate bent portions have been straightened out in this manner, the tendency which they have to return to their original positions, exerts spring pressure on opposite edges of the rail base.

The end 5 of the anchor is preferably formed with a lug 10 which extends substantially parallel with one edge of the rail base and is intended to be engaged by a suitable implement, for example, a crowbar, when the end 5 of the anchor is being forced outwardly from the rail so as to clear its outer edge. It will be obvious, however, that implements of various forms may be usedin applying the device, some of which rnay be employed more expeditiously when inserted between the rail and the [inner surface of the bend 5, or, otherwise suitably engaged with the anchor The configuration of the rail base receiving recess 11 is such asto provide a vertical shoulder 12 at one end and an overhanging jaw 13 at the other end which over the The backturned end a of the anchor is preferably formed with a notch 14 corresponding in configurationto the edges 15 of the recess 11 and fits over the edge 16 of the rail, so as to take a spring grip thereon. The end 5 of theanchor is formed with a similar notch 17 which defines jaws l9 and :20 adapted to engage the upper and lower surfaces oi": the edge 18 of the rail base, The upper aw 19 is preferably made shorter than the lower jaw 20, so to minimize amount of flexing to which the anchor must be subjected during its application to rail.

In applying the anchor to a rail, the jaws 13, 14 are hooked over one edge of a rail base, and the anchor positioned so that the tie-abutting foot 9 will bear against a tie. A crow-bar or other suitable implement may then be inserted betweenthe opposite edge of the rail base and the lug 10, or otherwise suitably engaged with the anchor, so as to flex the end 5 and body portion 6 sufficiently to permit the jaws 12 and 19 to clear the edge '18 of the rail. When the anchor is in its applied position, the jaws 19 and 20 of the spring end 5 engagewith one edge of the rail. at a point substantially midway between the jaws 13 and 14 engaging the other edge of the rail base. With this construction the spaced jaws 19, 13, 14 will support the tieabutting portion of the anchor in its proper position, and grip the opposite edges of the rail base with spring pressure, so as to resist any tendency that the vibration or other disturbing influences may have to displace the anchor or loosen its initial grip on the rail. When the anchor is subjected to creeping pressure of the rail, it will increase its grip on the rail base by a shackle hold, which grip is eifected by reason of the diagonal arrangement of the jaws 13, 19 with relation to each other, and the tendency which the anchor may have to increase such diagonal position by reason of its bearing Iggainst the'tie adjacent one edge of the rail ase.

What I claim is 1. In a rail anchor, a spring plate formed with back turned ends and an off-set formed between its ends, and having a recess between its ends for the reception of the foot of the. rail, there being a notch formed in the plate at one end of the recess and also in the extremity of each of the back turned ends. a

2. A rail anchor formed of spring plate, having back-turned ends and an offset and also a recess therebetween, the extremit of each back-turned end having a notch, t ere being also a notch at one end of the recess there-of, one of said back-turned ends having a projecting lug adapted to be engaged by a tool in prying the anchor into place.

3. A rail anchor comprising. a flat body I portion of spring metal cut away to provide a rail base receiving recess and having its opposite extremities bent backwardly and formed with notches adapted to fit over the opposite edges of the rail base, the body portion of said anchorlbeing formed with an off-set to provide a tie-abutting face and adapted to be strained when the device is applied to a rail.

4. A rail anchor comprising a spring metal member the body portion of which is recessed to provide jaw portions at opposite edges of a rail, and is bent backwardly at opposite ends to provide spring jaw ortions adapted to engage the opposite e ges of the rail base; said body portion being formed with an off-set for the purpose described.

5. A 'rail anchor comprising a spring metal member, the body portion of which is recessed to provide jaw portions at opposite edges of a rail base, and is bent backwardly at its opposite ends to provide spring jaw portions adapted to engage opposite edges of the rail base; said body portion being formed with an oiT-set and adapted to be straightened during the application of the device to a rail. i

6. A rail anchor comprising a spring metal member, the body portion of which is recessed to provide jaw portions at opposite edges of a rail, and is bent backwardly at opposite ends to provide spring jaw portions adapted to engage'opposite edges of the rail base, said body portion being formed with an off-set to provide a tieabutting face adjacent one end'of'the device and adapted to be straightened during the application of the device to the rail.

- 7. A rail anchor comprising a spring metal member formed at one end with a jaw adapted to hook over one edge of a rail base and at the other end with a shoulder providing a jaw portion adjacent the other edge 7 of the base; the opposite extremities of said
