57560 - 2 -

Traction devices between a locomotive and a wagon with a towbar are already known in the following constructions: "Screw coupling11. This is also used as a coupling between wagons. The screw coupling is not semi-automatic.

Semi-automatic traction devices are, for example, wide OTSO and VAPITI clutches operating with compressed air, in which the bracket is connected to the towbar from above, and clutches with a top-connecting but narrow drawbar loop and a guide funnel. Yes, these switches are semi-automatic in that they are connected and disconnected from the locomotive cab, so no one has to go between the wagon and the locomotive.

But these switches are for towing only. In addition, buffers must be used with these couplings to push the wagon or train.

The factory tracks have a lot of curves. Due to the buffers, the above-mentioned traction devices will not engage if the radius of curvature is small.

The traction and buffer device according to the invention eliminates this drawback because it does not require buffers.

The invention is characterized by the features set forth in the characterizing part of claim 1.

The semi-automatic traction and buffer device according to the invention is shown in side view in Figure 1 and in plan view in Figure 2. The locomotive buffer plate is 1. It has a rectangular hole 2 into which the square arm 4 of the clutch 3 fits so that by means of a screw 7 with a hand lever 6 and a chain Θ. The screw 7 is attached up and down to the flexible part 7 *. The body 3 of the coupling 3 has a pull loop 10 hinged by a pin 9. The pull loop 10 is drawn in the "open" position in Figure 1. It is raised to the "open" position either by the pneumatic cylinder 11 or by means of a lever 12 by a wire 13.

The end of the carriage is shown by line 14 and the towbar 15 is shown partly below the buffer projections 16 and drawn in broken line in Figure 1.

The entire traction and buffer device is thus one piece from the buffer projections 16 up to the threaded end 3 'of the arm 4.

The traction and buffer device is suspended in the locomotive body, e.g. by rubber springs 17. The buffer forces are received by the counter plate 18 and the traction forces by the plate 19. The tension of the rubber springs is adjusted by a nut 20.

The operation is as follows: When the locomotive is driven onto the carriage, the oblique leading edge 15 'of the towbar 15 raises the towbar 10 and then the towbar falls down onto the towbar. Now the locomotive can pull the carriage with the drawbar 10 from the towbar 15 or push the carriage with the buffer projections 16.

The drawbar is inspired by the grip with either compressed air or wire 13,

The traction and buffer device according to the invention is simple and reliable. It also works well in curves because no buffers are needed at all.

Claims (4)

A towing and buffer device for towed wagons or trailers for use on railway replacement locomotives and on tractors towing a trailer for road use, characterized in that it has buffer projections (16) on both sides of the trailer towing device and a pull-up part rising from the front. Traction and buffer device according to Claim 1, characterized in that the traction and buffer device is flexibly mounted on the buffer plate of the locomotive by means of a suspension which receives both traction and buffer forces. Traction and buffer device according to Claims 1 and 2, characterized in that it is arranged in an opening (2) in the buffer plate of the locomotive so that it can move forwards and backwards, but always remains in the upward position of the traction loop (10). Traction and buffer device according to claims 1, 2 and 3, characterized in that its rear part has a height adjustment so that the height of the rear part (3 *) of the arm (3) can be adjusted and the adjusting device allows the rear part to move forwards and backwards and is also flexible up and down.
