RAIL ANCHOR.

Application led April 20,

To all whom it may concern:

Be it known that I, LAURENCE J. BERKE- LEY, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee `and State of Wisconsin, have invented. certhe rail by spring pressure.

A more specific object of my invention is to provide an improved two-piece rail anchor comprising a. rigid yoke member, adapted to engage opposite edges of the base of a rail, and a. spring member cooperating with the yoke to hold it in operative engagement with the rail and adapted to resist the tendency which the vibration of the rail or other disturbing influences have to loosen the grip of the device on the rail.

A further object of my invention is to provide a rail anchor having a. rigid one piece yoke member formed at one e'fnd with a. hook-shaped portion adapted to lit over and engage the upper surface ofI one base flange of a rail and take a pinching grip on the upper and lower surfaces of said base flange, andv formed at the otherend with a vertically disposed abutment which engages the vertical edge only of the other base flange of the rail; the hook-shaped portion being formed whereby the yoke may be fitted on the rail by fitting the hook-shaped portion over one edge of the rail base and then raising the other end of the yoke to its operative position by rocking the yoke on a horizontal axis longitudinally of the rail.

The invention has for further objects the novel arrangements, constructions and combinations of parts, hereinafter described and claimed, for carrying out the above stated objects, and such other objects as will appear from the following description.

The invention is illustrated in certa-in preferred embodiments in tlie accompanying drawings wherein Fig. l is a side elevation of a rail anchor device constructed in accordance with my 1921. Serial No. 462,848.

invention, the samebeing shown in full lines in its operative position on a rail, the dotted lines indicating a position of the yoke member of the device Iwhile being applied to the 1 to 3 inclusive;

Fig. 6 is a plan view of a modified construction showing the device applied to a rail, the rail being indicated in dotted lines; and

Fig. 7 is a view in perspective of the yoke member shown in Fig. 6.

Like characters of .reference designate corresponding parts in the several figures of the dra-wings.

Referring first to Figs. 1 to 5 inclusive of the drawings: 10 designates a yoke member, made preferably of cast metal, formed at one end with a hook-shaped jaw portion 11 adapted to engage the vertical edge 12 and the upper and

lower surfaces

13 and 14, respectively, of one of the base flanges of the rail, and formed at t-he other end with a. vertically disposed abutment 15 which'en- .gages the vertical edge of the other base flange of the rail. The distance between the vertical portions of the jaw 12 and the abutment 15 is preferably, though not necessarily, substantially the same. as the width of the rail base, so that the yoke when applied Will stand substantially at right angles to the length of the rail. In order to facilitate the application of the device to a rail, the portion of the'yoke defining the lower part of the jaw 11 is inclined downwardly, as indicated at 16, so that the abut-- nient 15 will clear the edge of the rail when the anchor is in the position shown in dott-ed lines in Fig. 1. The portion of the yoke adjacent the jaw portion 11 is preferably wider than'the portion adjacent the jaw 15, and is .formed with a depending arm 17 which projects toward the tie 18 and functions as a fulcrum to tilt the yoke to cause the jaw 11 iiol to grip the upper and lower surfaces of the rail base. The lower end of the 'arm 1s formed with a fiat surface 19 providing a seat for a. curved spring or key 2() which thereby tilting the yoke) in a vertical plane so as to force the

edges

21, 22 of the jaw portion 1l into pinching contact with the upper and lower surfaces 13, 141 of the rail base. The tension of the spring 20, in

addition to rocking the yoke member sov as to effect a pinching grip on the upper and lower surfaces of the base fiange, exerts.

vertical pressure adjacent the edge 12 of the rail base, so as to support the abutment 15 of the yoke in its operative position adjacent the opposite edge ofthe rail base. The upper edge 23 of the spring 19 preferably inclines downwardly toward the longitudinal center of the rail so that the maximum vertical pressure of the spring will be exerted between the point 24 of the jaw portion 11 and the edge 12 of the rail base. The point 24 of the Jaw 11, it will be noted, provides the axis on which the yoke is rocked from the dotted line position (Fig. l) to its operative position.

A structure of the above character, being adapted to be rocked on a horizontal axis so as to bring the rail-engaging portions of the jaw 11 into gripping contact with the rail base, may be applied to rails having base flanges which differ in thickness or contour, as the clearance between the rail engaging portions of the jaw and the upper and lower surfaces of the rail will be taken up by the rocking movement of the anchor device.

In applying the device to a rail, the yoke is passed under the rail base at substantially right angles to the length of the rail,

and the hook-shaped jaw 11 'fitted over oneedge of the rail base, as indicated in dotted lines in Fig. 1. The abutment end 15 of the yoke is then raised until the yoke member assumes the full line position shown in Fig. 1. The spring member 20 is then positioned on the seat 19 of the arm 17 so as to engage with the under surface of the rail base at a point a short distance away from the tie 18, such, for example, as indicated in Fig. 2. The spring member 20 is held in this position and the yoke moved toward the tie, whereby the spring is tensioncd by bending the same to a more pronounced curve. The initial position of the springis preferably such that the movement of the anchor toward the tie. for example, from the position shown in Fig.

the outer surface of the spring bears against the tie. When the spring is force-d against the tie, for example, by the creeping movelment of the rail toward the tie, this pressure will have a tendency to straighten the spring and thereby increase its pressure against the under surface of the rail and the arm 1. so as to increase the pinching grip of the jaw 11 on the upper and lower surfaces of the rail base. Anyl clearance that may exist between the edges of the rail base and vertical faces of the jaw 11, and abutment 15 will be taken up by a slight skewing action of the yoke when the rail is subjected to a creeping pressure. Under such conditions the yoke will take a firm shackle hold on the vertical edges of the rail base.

In Figs. 6 and 7 I have illustrated a modification in which the inner edge of the .spring member 20a extends into a recess 26 when it is in its applied position so as to prevent displacement of the spring member during a retrograde movement of the rail. The lower end of the arm 17a of this modification is also preferably formed with a recess 19a adapted to receive the lower end of the spring member 20a. In other respects the device shown in these figures may be the same in construction as that shown in Figs. 1 to 5 inclusive. f

In applying this device to a rail, the spring member 20, when arranged in the position shown in Fig. 2, stands, as indicated in dotted lines, beyond the end of the lug 27 of Fig. 6 until the yoke is moved toward the tie to tension the spring. After the spring has been tensioned and positioned adjacent'the tie, it may be driven transversely of the rail until its inner vertical edge enters the recess 26.

While I have described my invention in certain preferred embodiments, it will be obvious that other modifications might be made without departure from the spirit of my invention. I therefore do not wish to be limited to the exact structures shown and described, except in so far as specific limitations may appear in the appended claims.
