IMPERIAL

PATENT OFFICE.

The subject of the present invention is an automatic rail fastening, which consists of two counter plates α and a ^l , two staples b and b ¹ , and the support plate for the rail c .

The two counter-plates α and a ¹ protrude with the shoulders η into the perforation of the cross-sleeper and, with their cylindrical part, serve to support the staples b and b ¹ .

The semicircular support of staples b and b ¹ allows them to perform an upward or downward rotary movement , but with staple b ^l the upward rotary movement is limited by the extension m of the counter plate a ¹ and the dimension χ of the perforation in the cross sleeper .

This limitation of the rotational movement in the Krampe b ^l , which is on the inside of the rail track, prevents tilting BEZW. a rotation of the rail in the direction of the arrow ^ and therefore the approach m of the counter-plate a ¹ serves at the same time to precisely secure the position of the railroad rail to the cross sleeper.

In the accompanying drawing, for example, the position of the approach m causes the railroad track to be supported perpendicularly to the cross sleeper; If the approach were to be shifted slightly downwards towards the transverse sleeper, an inclined position of the rail would be achieved, as is achieved, for example, when using the Haarmann's hook plate.

The support plate c ^{has two approaches c 1} corresponding to the width of the staples b and ^ ¹ as well as the perforation of the cross sleepers.

These approaches c ¹ engage in the perforation of the cross sleeper, thereby securing the. Position of the support plate on the cross sleeper and rest on the approaches ρ of the staples b and b ^l .

If the support plate is now loaded by the weight of the railroad track or by a train passing over it, so. If this pressure is absorbed by the approaches ρ of the staples b and b ^l , they tend to perform a downward rotary movement and therefore lie firmly on the rail foot above the cross sleeper. In order to avoid any excessive momentary stress on the cramps b and b ', the support plate c can also have a slightly curved surface, as can be seen in the drawing, which allows the support plate c to flex resiliently under heavy loads. The way in which the rail is inserted into the fastening can be seen from FIG. 2 of the drawing. The staples b belonging to a rail length are held in the position shown by simple brackets d; the rail is then lifted into position at an angle. After the clips have been removed, the rail already assumes the position shown in FIG. 1 due to its own weight, and the fastening is closed.

The fabrication of each. Fastening parts are made from rolled, precisely profiled river iron rods.

Claims (1)

Patent claim: Rail fastening, characterized by two on both sides of the rail in the perforations of the cross sleepers around counter plates d and α ¹ , which are secured in their position by lugs η , rotatable staples δ and b ¹ , which by means of lugs ρ from the rail to the Support plate c ″ together with their approaches c ^l exerted pressure come into effect in such a way that they lie firmly on the rail foot above the transverse sleepers and thus bring about secure storage of the rail. the more or less inclined position of the rail head by the approach m on the. inner side of the rails lying opposite plate a ^{1 is} secured. . , For this purpose ι sheet of drawings.
