Specification of Letters Patent.

Patented Nov. 2, 1920.

Application filed October 3, 1919. Serial No. 328,253.

To aZZcO hom it may concern: Be it known that I, HIRAM H. SPoNEN- BURG, a citizen of the United States, resid- .vice with abend which will mit the jaws ing at Gurnee, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Rail-Anchors,

of which the following is a specification.

My invention relates to rail anchors for resisting the tendency of railroad rails to move longitudinally and has for its'principal object to provide a novel form of anticreeping device which may be readily ap plied to rails, the base flanges of which vary in width or thickness, which when in operative position will maintain its initial grip on the rail with spring pressure so that it will not be displaced or loosened by the vibration of the rail or other disturbing influence, and which will take a biting hold on the rail base during a creeping action of the rail. i'

The above objects are obtained by making an anchor device with jaws, the distance between which is normally'less than the width of' the rail base to which the device is intended to be applied, and forming the deyield to perto beengaged with opposite edges of the rail base.

The invention also contemplates a device formed with a spring jaw which will yield to facilitatethe application of the device to the rail and which will bear with spring pressure against the upper and lower surfaces of the rail base.

The preferred form of my invention is illustrated inthe accompanying drawings wherein:

Figure l is a plan view of a railroad rail showing a rail anchor device constructed in accordance with my invention applied to the base flange thereof, a portion of the anchor device'being broken away so as *to illustrate the manner in which the device takesa biting hold on the rail base during the presence of a creeping action of the rail.

Fig. 2 is a front view of the device shown in Fig. 1, and illustrating in dotted lines one of the positions which the anchor device assumes while the same is being applied to the base flange of a rail.

Fig. 3 is a view in perspective of the anchor device shown in the preceding figures; and

Fig. 4 is a view in perspective of a POI? tion of a railroad rail showing my preferred form of anchor device applied thereto in operative position.

Like characters of reference designate like parts in the several figures of the draw- 1n s.

The rail anchor device illustrated in the drawings is preferably made from a flat piece of spring metal bent to form

jaw portions

10, 11, which engage opposite edges of the base flange of a railroad rail 12, and is provided with a downwardly extending portion 13'which abuts against one of the vertical faces of a cross-tie 14. The jaw portion 10 is formed by bending one end of MESNE ASSIGNMENTS,-

the metal blank upwardly to form an ir'reg- I rail base@ The portion of the metal blank intervening between said lips extends down- Wardly to provide a spring tongue 21 which engages the vertical edge of the rail base. The

lips

22, 23, being of sprin metal will yield when the jaw 10 is force on the rail, 0

base and bear with spring pressure against the inclined surface thereof, the resiliency ofthese lips in addition to holding the body portion of the anchor in frictional contact [with the bottom surface of the rail base so as to maintain a tight initial grip of the jaw on the rail, will also flex sufficiently to permit the application of the device to rails having base flanges which vary in thickness or contour] The body portion 24 is preferably offset, as shown at .25 to permit the tongue 21 to extend below the lower edge of the rail; the lower edge of the tongue being, preferably, bent inwardly, was indicated at 25 so as to extend a short distance under the base flange. The other end of the blank is bentfupwardly, as indicated at 26 to form the jaw 11, which engages the oppositeedge of the rail base. terminates in an outwardly projecting bend forming a loop 27. This loop facilitates the application of the device to the rail'by providing a curved surface 28 adjacent the jaw portion 11 adapted to ride over the lower edge of the rail base when the device is being L applied, and also provides a suitable hooked This'end of the anchor portion through which a crow-bar 29 or other suitable element may be inserted to enable the workmen to strain the bent portions of the device sufficiently to permit the edge 30 of the jaw 11 to clear the rail when the device is being applied. The tie-abutting flange 130i the device is arranged adj acent one end of the device, preferably adjacent the jaw 10 and the other end 18 made somewhat narrower than that of jaw 10, so that the jaw 11 will normally stand a short distance away from the tie. The tie-abutment 18 being formed at one end of the anchor will permit a slight skewing action of the device when the rail tends to creep to: ward the tie, and in this way tension the device to increase the grip of the device on the rail base. The lip 21 of the jaw 10 andthe vertical portion 26 of the jaw 11 are formed with

sharpv edges

31, 32, which are adapted to take a biting-hold on the vertical edges of the rail during the said creeping action so as to prevent any appreciable relative movement between the rail and the anchor device. If desired-the sharp edges may be embedded into the edge of the rail when the device is being applied by striking the portion on which these edges are formed so as to drive the sharp edges into the rail.

- When the anchor is thus far applied it astill sumes the position illustrated in dotted lines in Fig. 2. A crow-bar or some suitable device is then inserted through the hook portion of the jaw 11 and the anchor sprung in the direction indicated by the arrow in Fig. 2

until the edge 30 of the jaw 11 clears the edge or the rail, as shown in full lines in the drawing. The rear edge of the portion 26 of jaw 11 and the forward edge of the tongue 21 of the jaw 10 may then be tapped till) hill with a hammer or some suitable device to embed the

sharp edges

31, 32 in the vertical edge of the rail.
