ROLANDIS A. BLAIR, OF FORT WAYNE,'INDIANA, ASSIGNOR TO THE P 6: M COMPANY, A OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

RAIL ANCHOR.

Application filed June 5,

To all whom it may concern:

Be it known that I, BoLANnrs A. BLAIR, a citizen of the United States, residing at Fort W'ayne. in the county of Allen andSta-te of Indiana, have invented certain new and useful Improvements in Rail Anchors, of which the following is a, specification.

My invention relates to rail anchoring devices of the character adapted to grip a rail and abut against a stationary part of the road-bed, to resist the tendency of the rail to cree longitudinally in the direction of the tra c.

An object of the invention is to provide an improved one-piece anchor that will be inexpensive to manufacture, that will take a combined spring grip and shackle hold on the base of a rail; that will increase its grip on opposite edges of the rail base during the 26 presence of any creeping movement of the rail; that will maintain its maximum spring grip on the upper and lower surfaces of the rail base; and that will be easy of application to or removal from a rail.

A more specific object of the invention is the provision of a rail anchor embodying the new and improved constructions and opera tions hereinafter described and claimed for carrying out the above objects, and such 3 other objects as will appear from'the following description. I i

The invention is illustrated in a preferred embodiment in the accompanying drawings, wherein like characters of reference desig- 5 nate-lilte parts. and wherein- Fig.1 is a fragme'ntary plan view'of a' railroad rail and cross tie, showing a rail anchor constructed in accordance with my invention applied in its operative position on the base flange of said rail.

Fig. 2 is a side view of the rail anchor shown in Fig. 1, the rail to which it is applied being shown in section.

"Fig. 3 is a view similar to Fig. 2. show- 5 ing the position assumed by the anchor device during its application to a rail; and

Fig. 4 is a view in perspective of the rail anchor device illustrated in the preceding figures.

In the drawings 1 have shown my improved rail anchor applied on the base flange of a railroad rail 10,, in a position to abut against a cross-tie 11.

The anchor is made from a single bar 'of 1922.. Serial No. 565,822.

steel, preferably round in cross-section, and 1s bent to provide means for engaging opposite edges'of the rail base and means which exert spring pressure against the upper and lower surfaces of the rail base. The anchor, preferably, comprises a. body portion 12 which extends across the rail base, formed at one end with an upstanding portion 13 adapted to engage one edge of the rail base, and provided adjacent the other edge of the rail base with a double hook-shaped jaw portion 14 which projects over the upper surface of the rail base. The aw 14 consists preferably of substantially

parallel portions

15 and 16, connected .by means of a lateral bend 17. The portion 16 terminates in a relatively large semicircular arm 18, providing means for bearing against avertical face of the cross-tie 11. The extremity 19 of the tieabutting portion also bears against the under surface of the rail base, preferably adjacent the vertical center of the rail. The vertical distance between-the bearing point 21 of the double jaw lei and the extremity 19 of thetie abutting portion 18 is normally less than the thickness of the rail base to which the anchor is intended to be applied. lVith this construction the. bearing

surfaces

21 and 19 will be forced apart when the double hook portion 14 is forced upon the inclined surface of the rail base, and will thereby exert a spring grip on. the upper and lower surfaces of a rail base.

The distance between the surfaces 22 and 2'3 (Fig. 1), is normally greater than the width of the rail, so that the body portion 12 will assume a position diagonally across the rail base, and thereby effect a firm shackle grip on opposite edges'of the rail when the anchor is in its applied position.

The tie abutting portion 18 is preferably disposed at an angle to the body portion 12 so that the tie abutting port-ion will bear fiatwise against the tie whcn the body portion 12 is in its normal diagonal "position. The body portion 12 is preferably bent downwardly, as indicated by the reference charactcr 21. so as to provide an anchor in which the body portion 12 will be subjected .lo a minimum distortion during the application of thc device to a rail.

. In applying the anchor to arail, the double hook portion 14 is fitted over one of the base flanges of the rail base, substantially formed with 70 af a rail base vii n which bears aid base and My ail ans e edge facaortion G S G 5 nu .1 1 2 2 3 i S V 5 SQ M aces 0 iii) bar provided at one end with means for engaging one side of the base of a rail and at the other with a jaw to engage the other side of the rail base which is formed with a curved arm extending around and spaced from the edge of the rail base with its extremity upturned and bearing against the under side thereof. 7

13. A rail anchor comprising a spring bar provided at one end with means for engaging one 'side of the base of a. rail and at the other with an expansible jaw to engage the other side of the rail base which is formed with a curved arm extending around and spaced from the edge of the rail base and bearing against the under side thereof.

It. A rail anchor comprising a spring ar provided at one end with means t'or engaging one side of the base of a rail and at the other with a jaw to engage the other side of the rail base which is formed with an extension adapted to bear with spring pres sure upon the rail to flex the top of the jaw down upon the upper surface of the rail base. i

15. A rail anchor consisting of a metal bar. one end of which is provided with means for engaging one edge of the base of a rail. an intermediate portion of which is bent to form means for engaging the other edge of saidrail base and the other end of which is adapted to intervene between said rail engaging means so as to be depressed when the anchor is applied to the rail to produce spring action in the grip of the anchor on' the rail.

It). A rail anchor formed from a bar bent intermediate its ends to provide two legs, one otwhieh is bent to provide a hookshaped jaw to engage one edge ota rail base and the other providing a spring member adapted to hear at its extremity against the under surface of the rail base.

' l7. rail anchor composed of a metal bar bent upon itself to provide two legs, one of which extends across the under surtaco ot' a rail base and is formed with a. hooteshapml jaw portion adapted to engage the upper inclined surface of a rail base at' one side of the rail. the other of Said legs being bent to project under the rail base and bearing at its extremity against said under surt'ace ot' the base adjacent said hook-shaped jaw.
