This invention relates to flange shoes or clips in one piece for rail joints, which may be passed obliquely over the rail flange and secured in position. As compared with flange clips consisting of a plurality of parts, the present clip possesses not only the advantage of great strength, but by the uniform tightening of the claws which clamp on the rail flange on both sides, it also avoids any deformation or buckling of the rail flange, such as is always possible in the case of rail clips consisting of a plurality of parts. Moreover, the uniform construction and simple securing means ensure a reliable and lasting fixed position. The clip is secured by one or more longitudinal keys which may be tightened by a transverse key. An intimate tightening of 7 all parts of the rail joint is thus effected by the transverse key in conjunction with the tightening action of the longitudinal key or keys. Instead of one transverse key, a transverse key and a separate longitudinal key may be arranged for each rail end. The rail joint may also be given an upward lift by suitably cutting away the bearing faces of the claws.

Two constructional examples are shown in the accompanying drawings in which Fig. 1 shows a rall joint with a flange clip in one piece,

Figs. 2, 3 and 4 show sections respectively along A-A, BB and C-O in Fig. 1.

Fig. 5 shows the flange clip in section in an oblique position and without a key, as it is being passed over the rail flange;

Figs. 6 and 7 show a special flange clip in cross-section and longitudinal section;

Figs. 8, 9 and 10 show a construction ofthe flange clip with two longitudinal keys in cross-section and side view, as well as in lon gitudinal section through a lateral recess of the clip.

The flange clip 1 (Figs. 1 to 4) in one piece, has a substantially U-shaped cross-section,

and has on its lateral limbs claws 2, which are adapted to clamp both sides of the rail flange 3 when the clip is placed in position and tightened. The height of the lateral limbs, the depth, the recess under each claw, and the clearance between the claws 2 are so dimensioned that the clip 1 may be passed obliquely over the rail flange from below until the claws lie above the rail flange (Fig. 5).

After the clip 1 has been passed over the rail flange, the securing means may be assembled, namely, a longitudinal key 4. and a transverse key 5. 'The longitudinal key is dimensioned so that, with a suitable wedge taper, it tightens each claw 2 against the rail flange (Figs. 1 to 4) the transverse key 5 act ing as a locking key and effecting the final tightening. In addition,;the ends of the rails are connected in the known manner by fishplates 6 with bo1ts7.

In order to give the rail joint an upward lift, the bearing faces 8 of the claws may be suitably cut away or bent'outwardly, asiin Figs.6 and 7.

Inthe construction shown in Figs. 8 to 10, the tightening below the rail flange is effected by separate short longitudinal keys 4 inserted on both sides of a transverse key (or several transverse keys). A lower trans verse key 9 serves for tightening the longitudinal keys 1' while an upper transverse key 5 serves for tightening allparts of the rail joint in a vertical direction. 3

I claim:

1. A one-piece flange clip for rail joints with fish-plates, said clip being U-shaped in cross-section and being provided with lateral claws spaced to permit the clip to be passed 7 sidewise obliquely over the adjacent flanges separate short longitudinal keys below the rail flange for tightening the oint, and other keys'passing transversely through'the lateral parts of the flange clip and lying between said longitudinal keys, one of said transverse keys acting on the adjacent ends of the short longitudinal keys.

2. A one-piece flange clip of U-shaped cross-section for rail joints with fish-plates said clip having lateral claws spaced to permit the clip to be passed sidewise obliquely over the adjacent rail flanges, transverse keys passing through the lateral parts of the flange clip, and separate short longitudinal keys being inserted into the clip. on both sides of the transverse keys, the lower one of said transverse keys acting upon the ends ofthe PATENT ome:

v cross-section and beingprovided with lateral adjacent short longitudinal keys and the upper one of the transverse keys acting in vertical direction for tightening all parts of the rail joint in this direction.

3. A one-piece flange clip of U-shaped j cross-section for rail oints with fish-plates, said clip having lateral claws for embracing both sides of the rail flange with only small tlghtening means,

parts of the claws when placed in position,

said clip also having a clearance below the clamping portions of the claws for receiving tightening means and an additional clearl ance below the clamping portions coacting with the enlargedaperture between the claws, so that the clip may be passed sidewise obliquely over the adjacent rail flanges. I

4; A unitary flange clip for rail joints with fish-plates, said clip being U-shaped in crosssection and being provided with lateral claws spaced to permit the clip to be passed sidewise obliquely over the adjacent rail flanges and having a suficiently enlarged clearance below the clamping portions of the claws to admit the-rail flange-in passing the clip sidew wise obliquely over it and to receive tightening means. V

5. A unitary flange clip for rail oints with fish-plates, said clip being U-shaped in crosssection and being providedwitli lateral claws spaced to permit'the clip to be passed sidewise obliquely over the adjacent rail flanges and having a sufficiently enlarged'clearance below the clamping portions of theclaws in order to admit the rail flange in passing the clip sidewise obliquely over it and to receive longitudinal tightening keys adapted to be inserted below the adja cent rail flanges and transverse keys passing through the lateral parts of the flange clip and movablein 'a'horizontal direction to tightening'the longitudinal keys and in a vertical direction for sustaining the rail ends.

6. A unitary flange clip for rail joints with fish-plates, said clip being U-shaped in claws spaced to permit the clip to be passed sidewise obliquely over the adjacent rail flanges, and means for tightening said claws and sustaining the rail ends, the claws having in the middle of their length above the opening for the transverse keys an elevated portion to give an upward lift to the joint.

In testimony whereof I afiix my signature.
