In accordance with the invention it is advantageous Johan F. Deenik and Jacob A. Eisses, Bilthoven, Nether lands, assignors to Everts & Van Der Weyden N.V., rail is in contact with the top portion of the strap. This Helmond, Netherlands, a company of the Netherlands construction offers the advantage that in the case of a if the outer side of the raised border ?ange adjacent the Filed July 8, 1960, Ser.

(Cl. 238--315) straining force on the locking plate through the ?ange. 10 In accordance with the invention such a force can also be supplied when each leg of the strap has a collar or support by means of a resilient clamp. The invention has for its object to provide such a fas tener which can be applied universally to sleepers formed of all types of materials and portions of which may be 15 premounted on the sleepers before delivery to the right shoulder of which the upper surface underlies the plate and is coplanar with the upper surface of the support. The locking plate ?nds then a certain support on this col of way. means of an adhesive which also may provide insulation against electric current. In the case of a metal railway This invention relates to the ‘fastener of a rail on a In accordance with the invention, a locking plate with a raised border ?ange around three sides lies on either lar or shoulder. Finally the strap can be fastened in the support by sleeper, the strap can be fastened to the railway sleeper side against the rail foot, and this plate is locked against 20 by means of welding. The invention will be further described hereinafter horizontal displacement by a U-shaped strap, the plane with speci?c reference to the drawing, in which: of which is parallel to the direction of the rail and the FIG. 1 is a view in perspective of a fastener according to the invention; FIG. 2 is a fragmentary view in perspective of a modi the horizontal body of the U-shaped strap is spaced above 25 ?ed strap; the upper side of the plate by the side ?anges, and the FIG. 3 is a view in perspective of another modi?cation loop of a U-shaped bent resilient clamp lies on the plate of the strap; under the body of the strap and with its legs bent towards legs engage each in a gap on both sides of the plate and which are fastened in the material of the support, while the rail and then backward more than 90° toward the loop, which legs press on the rail foot with the free ends abutting the ?ange whereby, in an unstrained condition, the distance between the loop and the free ends of the clamp legs is greater than the thickness of the body of the strap in the direction perpendicular to the rail. Such a fastener can be applied to railway sleepers of all kinds of material. In the case of a railway sleeper of soft Wood, a supporting plate is applied, whereby the plate is FIG. 4 is a cross sectional view taken perpendicularly of the rail through the fastener shown in FIG. 1. FIG. 5 is a cross sectional view similar to FIG. 4 and showing a modi?cation of the fastener, and FIG. 6 is a cross sectional view similar to FIGS. 4 and 5 and showing still another embodiment. In FIG. 1, the fastening of one side of the rail foot 1 of a rail is shown. A locking plate 2 having a raised border ?ange 3 is positioned with said ?ange against the elastically pressed on the Wood by the reaction force of the resilient clamp. The railway sleepers or blocks are side of the rail foot 1. The locking plate 2 has gaps 4 in its ends through which pass the legs 5 and 6 of a above and around the body of the strap and is then way sleeper on which the rail rests. conveyed to the right of way with premounted straps 40 U-shaped fastening strap. The lower ends of the legs 5, 6 of the strap are fastened in the material of the rail and locking plates. The resilient clamp is mounted from The strap has a .horizontal bight portion or body 7 which bears on the upper surfaces of the cams or ?anges 8 at the ends of of the legs rest on the rail foot and abut the side of the ?ange adjacent the rail. The rail is ?xed between two 45 plate 2, providing a space between the body 7 and the pressed in the direction of the'railfoot, whereby the ends locking plates by which the rigidity of the frame of the track is considerably increased. Moreover these locking plates facilitate exact placement of the rail when con structing a railway track. plate 2. In this space is ?tted the loop 9 of a U-shaped bent clamp 10, the legs of which are bent upwardly and over towards the rail and the free ends 11 and 12 of the legs The raised border of the locking plate, in a very prac 50 are bent under more than 90‘? toward the loop 9. The ends 11 and 12 abut the raised border ?ange 3 and press tical embodiment, is provided with a central transverse on the rail foot 1. The free ends 11 and 12 are spaced groove the bottom of which merges with a bevel rising from the loop 9 so that the clamp 10 can be mounted from the upper surface of the plate and is substantially around the strap from above, after which the clamp can level with the upper surface of the rail foot, and the width of this groove is smaller than the distance between the 55 be pushed toward the rail foot 1 with loop 9 underlying the body 7 of the strap. outer sides of the free ends of the unstrained clamp. The ?ange 3 has a transverse groove 13, as best shown When the clamp is displaced horizontally the free ends in FIG. 4, the bottom of which is connected by a bevel of the clamp legs are carried upwardly by the bevel and 14 with the upper surface of the plate 2 and which forms by pressing them together they can pass through the groove after which the free ends spring apart behind the 60 a ramp between the upper surface of the plate 2 and the rail foot 1. When mounting the clamp, the ends 11 and ?ange and lock the clamp against retraction. 12 are pressed together so that they can be pushed into Moreover, in accordance with the invention, the side the groove. Then, as the clamp 10 is ‘forced toward the ?anges of the locking plate are upwardly inclined to the rail its ends 11 and 12 rise along the bevel 14 and sub strap supporting portions the heights of which are greater sequently rest on the rail foot 1, after which the ends 65 than the thickness of the loop of the clamp. Thus, the spring apart and the clamp is locked against retraction strap cannot be pressed too 'far in the support which by the ?ange 3. would leave insu?icient space for the clamp. The height and length of the ?ange 3 is greater than Furthermore, in accordance with the invention, the dis that of the side ?anges 8 and is engaged by the rail side tance between the inner surfaces of these cams can be 70 of the strap portions 5, 6, 7. Should the plate sink into substantially equal to the width of the loop of the clamp. The clamp is then locked against rotary movement about the material of the railway sleeper and tend to twist rela tive to the rail, it is restrained by the engagement of the 3,067,947 4 3 outer side of the ?ange 3 with the adjacent side of the strap. FIG. 2 shows an embodiment in which the legs 5 are provided with a ‘shoulder 15. The plate 2 then rests on both the railway sleeper and the shoulder 15. In FIG. 3 the body 7 of the strap has a bend 16 di rected away from the rail. As a result the loop 9 is more quickly engaged under the body 7 of the strap when wardly over the strap and then moving the clamp loop un der the strap. 2. A fastener in accordance with claim 1, character ized in that said border ?ange at said one side has a transverse groove in its upper surface extending com pletely through the ?ange, and of a width smaller than the distance between the outer sides of the free ends of the unstrained clamp, whereby the resilient clamp upon as sembly is inserted under the strap with the free ends of The embodiment according to FIG. 4 shows how the 10 the clamp legs in said groove, the clamp when moved toward the rail freeing the clamp legs from the groove. clamp 10 presses on the rail foot and is held by the body 3.
