Description

Spring tongue for tram turnouts The spring tongues for the previously known ones Roller rail turnouts have such a shape; that they are made only by forging can be. The further processing is made more difficult, the manufacturing costs a finished tongue are therefore quite important. One is ready as an example machined tongue a shown in Fig. i, the one at the root end a lateral Lobes, in Fig.z it has two lateral lobes for attachment to the adjacent Grooved rails b (Fig. 3 and 4) are used. The whole tongue with these rags must be out forged out of the full material and the reduction in cross-section required for suspension must be made by milling out the grooves c from the full cross section.

The novelty of the invention lies in the fact that the entire length tongue of the same height made from a rolled section (Fig. 5 and 6) and the grooves c, are rolled in at the same time, whereby the root end of the tongue is so divided and is designed so that rolling is prevented thereby from reaching. For diesel purpose the lateral foot of the rolled section is kept so wide that by riveting or Welding a correspondingly shaped part, d (Fig. 3 and 4) on the tongue foot the root end of the tongue can be made in the desired shape without the forces occurring at the root end have a detrimental effect on the position of the tongue to have. The attached part receives what is required for the respective fastening Shape so that the rolled profile of the tongue is not changed. If needed. can both The tongue feet must be kept so wide that molded parts are riveted on both sides will. can (Dept. 4). The manufacturing costs of a spring tongue rolled in this way are significantly less than a tongue made from a forged piece.

The new arrangement is illustrated in the accompanying drawing. Fig. I eats a floor plan of a finished spring tongue with a lateral. widened Base made of solid material.

Fig. Z is a plan like Fig. I, but with two widened sides Feet made of solid material.

Fig. 3 eats a cross-section through the switch leg. at the root end the tongue, with the lateral flap passing through a tongue made by rolling A shaped piece is made on the tongue base by riveting or welding.

Fig. 4 is a cross-section through the switch leg at the root end the tongue, with two lobes of a tongue made by rolling through Riveting or welding of fittings on the tongue feet are hexgesbellt.

Fig. 5 is a plan view of a tongue made by rolling foot extended on one side.

Fig. 6 shows a plan view of a tongue made by rolling feet extended on both sides.

Fig. 7 is a cross section of Fig. I in the direction of the arrow.

Fig. 8 is a cross-section of Fig. Z in direction.
