SU8453A1 - Automatic coupler for railway cars - Google Patents

Description

The present invention relates to an automatic coupling device intended for railway cars, and allowing it to be uncoupled from the side of the cars and moving from an automatic coupling to an ordinary one.

In FIG. 1 depicts a top view of the proposed device; Fig, 2 side view; FIG. 3-connecting bolt; FIG. 4-cross-section of the head; FIG. 5-side view of the latch; FIG. b-front view; FIG. 7-buffer rail car; FIG. 8-arm for a rod with a handle.

The proposed coupling device consists of an elastic hook 1 (Fig. 1 and 2), fortified in the frame of the car and having an axis 2, on which the device case 3, hingedly connected with a fork, is suspended; part of his shoulder 4 with bolt 7 with spring strung 5, located in the buffer rail of the car. Connecting bolt 7 (Fig. 3), having a band connected with a chain b attached to the buffer bar; on the circle end of the bolt 7, the axle 8 is fixed, on which a double-arm lever 9 is mounted, which prevents accidental

open the device. In the front part of the housing 3, the coupling head 11 is rotatably fixed on the axis 10 and is provided with a serrated surface.

12 (fig. 4), the shoulders 13,13 and the arcuate process 14. A latch is used to fix the head 11. 15 (FIGS. 5 and 6), consisting of a rod with a slit 16 and a head 17, provided with an axis 18 on which the stopper 19 rotates, having a protrusion 20, a step 21 and a spike 22. In the case 3 there is a socket for the latch 15 provided ledge 23 and shoulder

13 heads 11-groove 24. Handle 25 and knee 26 (fig. 7) located on rod 27, led to the buffer bar, on loop x 28 and supported when the train is moving in bracket 29 (fig. 8) serve for uncoupling the instruments.

When the cars are coupled, the heads 11 of the devices deviate around the axes 2 of the hooks 1, go one after the other and close under the action of the springs 5 of the rod 5. If one or both heads 11 are not in the working position before coupling, then when the cars come close, the end of the head 11 one device presses on the shoulder 13 of the other head and

rotates it about the axis 10 to the working position when the latch 15 of one or both devices closes them.

The uncoupling of the cars is made by turning with the help of the handle 25, the rod 27, the shoulder of which 26, acting on the head 17, lifts the latch 15; finally, by its slot 16, frees shoulder 13 and allows heads 11 11 to turn around axis 10 and disengage the instruments. When the head 11 is rotated, the finger 31 rests on the tide 32 of the housing 3, designed to limit the rotation of the head 11 near the axis 10.

Maneuvers are performed with instruments previously uncoupled; the stopper 19 supports the raised latch 15 until the head 11 is deflected and disengages the devices. When the latch 15 is closed, the process 22 of the stopper 19 is pressed between the wall of the slot 16 of the latch 15 and the ledge 23 of the housing 3. When the latch is lifted, the process 22 slides along the ledge 23 and at the appropriate height, the stopper ledge 21 drops beyond the edge of the notch 24, since the projection 20 with its weight it tends to turn the entire stop near the axis 18. In this position, the latch remains until the shoulder 13 of the head 11 is rotated. When the head 11 moves, the edge of the recess 24 of the shoulder 13 presses the ledge 21 against the latch rod and releases the latch 15, which is dropped by the arcuate process 14 of the head 11 when it falls.

For coupling the cars with an ordinary screw tie, the proposed device is disconnected from the spring rod 5 and retracted away from the axis 2. The connecting bolt 7 is inserted into the holes 30 of the housing 3 and holds the device between the buffer bar and the hook 1. The tie rod, located in the hole of the hook 1, is closed on the other side by the arm 4 of the body 3.

When the body 3 breaks near the axis 10, the device does not become disengaged, since the head 11 is fastened with a latch 15 between the shoulder 13 and the tide 32; when the housing 3 breaks near the axis 2, the housing shoulder 4 extends behind the pull hook 1 and holds the device in the clutch.

The subject of the patent.

1. An automatic coupling device for railway cars, allowing it to be unlocked on the side of the car and changing from an automatic coupling to an ordinary one, characterized in that the coupling head 1, 3 (Fig. 1 and 2) of the device, hinged on a conventional hook, has a conventional design, a head installed in a horizontal position, provided with a shoulder 4j, the end of which, in order to give the coupling head the capability required for coupling the deflection cars, is pivotally connected to the rod 5 spring-attached to the buffer bar of the carriage.

2. The form of execution of the coupling device described in paragraph 1, characterized in that the rotary part 11 of the coupling head is provided with an arcuate process 14, holding, when the device is uncoupled, the latch 5 (Fig. 5 and 6) in the non-working position, and the shoulder 13 , perceiving the impact of the rotary part 11 of the adjacent coupling head, in order to position the coupling head in the operating position.
