Claims priority, application Netherlands January 21, 1954 2 Claims. (Cl. 238349) The invention relates to rail spikes, and more particularly to devices for resiliently urging rails against sleepers.

Various known kinds of resilient spikes have the drawback that they themselves have to press the rail onto the sleepers, owing to which the spikes have to be eX- tracted entirely or partially for the release of the rail. This and the refixing or pressing of the spikes after the mounting of another rail is not only a time consuming operation, but also the grip of the spike legs in the wooden or concrete sleeper will diminish thereby because the holes are enlarged by such manipulations.

The invention contemplates a so-called direct fastening of the rail, i. e. a fastening in which for the arrangement or removal of the rail the main fastening means, namely a resilient spike, collar screw or the like remains unaltered in connection with the sleeper and the grip on the rail bottom is effected by a clip releasable from the main fastening means.

In these constructions the clip at one side bears on the rail bottom and at the other side on a sole plate, chair, or immediately on the sleeper. The pressing force exerted by the main fastening means herewith acts only partly on the rail bottom, whereas for the part of ,the clip which comes to rest on the sole plate, chair or sleeper a provision is to be made at the sole plate, chair or sleeper.

The result of the latter is that for each kind of clip only an appertaining sole plate or chair is suitable and universal application of a certain clip to various kinds of sole plates or chairs is impossible whereas known constructions in which direct fastening has been applied cannot easily be converted to the indirect fastening type.

According to the invention the clip is releasably interlaced with the spike in such a manner that the clip will anchor into the spike as soon as the spike starts producing its gripping action, the clip then acting as a unit With the spike.

In a practical embodiment of the invention in which the spike is of the two-legs type which through helicoidal windings are connected with a bridge piece, and consequently are connected with each other by a loop. The clip is substantially T-shaped, the cross member of the T being arranged such as to be supported on the inner side of the helicoidal windings and by means of an ofiset part merging in the vertical part of the T in such a manner that the latter may bea r against the lower side of the bridge piece of the spike.

The resilient clip according to the invention may be arranged in and removed from the resilient helical spike by lifting the loop over a slight distance by means of a claw wrench and it fastens itself between the rail bottom and the loop as soon as gripping action is given back to the loop by the loosening of the claw Wrench. The

clip is, as it were, an elongation of the loop which as a result of the pressure produced by the loop clamps the rail bottom to the sleepers.

2,844,326 Patented 22,. 1958 The end of the loop of the helical spike does not extend further than to a certain distance from the rail bottom, owing-to which after removal 'of -'the'elips, which may be achieved rapidly with this construction, the rail may be removed quickly and replaced by another, without the grip of the spike legs in the sleeper being unfavorably influenced thereby.

In the drawing:

Fig. 1 is a sectional view of a rail illustrating the engagement thereof by a spike and clip provided in accordance with one embodiment of the invention;

Fig. 2 is a top plan view of the structure shown in Fig. 1;

Fig. 3 is a view similar to that shown in Fig. 1, illustrating a further embodiment of the invention;

Fig. 4 is a top plan view of the structure of Fig. 3;

Fig. 5 is a view, similar to that shown in Fig. 1, illustrating a third embodiment of the invention;

Fig. 6 is a top plan view of the structure of Fig. 5; and

Fig. 6a shows, in enlarged scale, a detail of Figs. 5 and 6.

Similar arrangements are useful for soft-wood sleepers with sole plates adequate to soft wood, and for concrete sleepers bearing the rails directly by means of a resilient pad.

The resilient spikes shown in the figures have two legs 1 and 2 connected by means of helicoidal windings 3 and 4 to a bridge piece 5, which per se cannot press down the rail bottom 6.

This is achieved through a clip 7 which is interlaced in a simple manner with a spike.

The clip 7 is substantially T-shaped (vide Figs. 2 and 4) and is punched, e. g. from strip material.

The cross member 8 of the T, bearing on the parts 3a and 4a of the windings is pressed downwardly to get a hold against a slanting set up.

Said cross member 8 with an ofiset part 9 merges in the vertical part 10 of the T which comes to rest below the bridge piece 5 of the spike and with its free end engages the rail bottom.

When the parts -3a and 4a of the windings are lifted somewhat with a claw wrench 11 (Fig. 3)the spike remaining fully in positionthe clip may be removed.

Figures 1 and 2 show the application of the invention with a sole plate 12 which at the same time supports the rail bottomfi laterally and with a concrete sleeper 13.

The extremity 14 of the loop (Fig. 1) here extends beyond the spike legs.

When one is satisfied with not using sole plates or the like but by having the rail rest immediately on the sleeper 16 by means of a resilient pad 15 and to have the lateral support of the rail bottom efiected by the spike legs, the extremity 14 of the loop remains inside the spike legs as indicated in Figure 3, showing the arrangement for hard wood sleepers. The clip according to Figs. 5 and 6 has a somewhat altered shape. This clip can be manufactured in an easier manner. Here the clip (see Fig. 6a) has the ends of the cross beam of the T offset at 17.

With the clip according to the invention an indirect rail fastening with resilient spikes is achieved in which the grip produced by the spike is fully transmitted to the rail bottom. The unit is independent from the shape or the profile of the sole plates and the like. Also without application of sole plates and the like an indirect rail fastening is obtained without bolt and nut fastenings. Consequently the construction is universal. T

What I claim is:

1. A rail fastening device comprising a spike; said spike including two legs, a bridge piece and helicoidal 3 windings connecting the legs with the bridge piece; and a substantially T-shaped clip comprising a cross member supportable within the helicoidal windings and an offset member coupled to said cross member and supportable against the bridge piece of said spike.

, 2. A device as claimed in claim 1 wherein said offset member is merged in the vertical part of the T, said vertical part being connected with said cross member.
