Description

Automatic coupling devices for railway carriages are known, which are provided with cam coupling heads or heads with swivel hooks and coupling brackets and also include a device for coupling with a conventional screw clamp of a neighboring car. In such a device, a coupling head is offered, with the aim of being able to center it, to be fixed on the pn or spring transverse beam mounted movably and pivotally in brackets attached to the buffer bar. In addition, it is proposed to use a coupling head in which the hook is locked in the working position by a spring latch operated at the side of the car and a coupling head in which the coupling fist is gripped between the folding hook and the hook formed by the corresponding recess in the cage.

In the schematic drawing of FIG. Figure 1 shows the device of the proposed device for strengthening coupling heads with the use of a hinged beam; FIG. 2- the same, with the use of spring beams; Fig.Z and 5-proposed coupling heads in the working position; FIG. 4 is a cross-section of the coupling head shown in FIG. 3

Two brackets 1 are attached to the buffer bar 10 (fig. 1) connected to the side frame of the railings of the carriage, using two square brackets 1, equipped with pivoting bolts 3 of the sleeves 2 with washers 2 fitted on the bushes. cross sections of the same cross section of the rods 5 of the hinge beam 5-6-4-6-5, to the middle core 4 of which is attached respectively arranged coupling and centering head A. The free ends of the rods 5 are screwed 7 cups, between which the cups and bushings 2 are placed conical springs 9. Installed Single coupling heads to the center position in the horizontal direction is achieved by rotating the cups 7 and the vertical rotation of screw-3.

Shown in FIG. 2, the device of the proposed device differs from that described only by the fact that instead of a hinged beam, a spring 8 is used, the ends of the middle plates 8 of which are made in the form of a cone covered by two outside rings screwed on the outside 7 on which the cup 7 is screwed.

The coupling head (fig. 3), fixed on the articulated or spring beam of the device, is provided with a shackle and two hooks: an upper hook b and a lower swivel hook with a tooth I. The hook s in the working position (shown in the drawing) is clasped with a spring the latch fj of the head placed in the cages (Fig. 4) and controlled from the side of the carriage by means of the lever r mounted on the protrusion W; In addition, the coupling heads are provided with attachments K for coupling with conventional car couplings.

As the cars equipped with the proposed coupling devices come together, the earrings and into the space between the hooks yen, the pressure on the I gear, force the hooks to lift, and the latter are automatically locked by the spring latch f. For splitting, the latch I is pulled out, so that the hooks with are lowered by a certain amount corresponding to the gap between the link and the tooth I of the hook with. Then the earrings are removed from under the hooks.

FIG. 5 shows a coupling head, different from that indicated in that instead of an earring, a coupling arm KI is arranged, and the hooks Ci and bi have a corresponding shape.

The subject of the patent.

1. Automatic coupler for: 9 electric carts stocked with

cam coupling heads or heads with pivoting hooks and coupling brackets and also including a device for coupling with a conventional screw tightening of an adjacent carriage, characterized by the use of movably connected with brackets 1, 1 on buffer bars (figs, 2, 1) equipped with pivoting bushings 2, of the transverse beam carrying the coupling head and consisting of either a spring 8 (Fig. 2) or a hinge lever 4, b, 5 (Fig. 1), which beam can move within the established limits along its axis, under the influence of its end x spring capacitors 9, 7, cups 7 of which, screwed on the ends of the beams, allow for the proper installation of the coupling head relative to the longitudinal axis of the wagon.

2. Use the three hitch-head device described in item 1, in which the hook c (fig. 3) in the working position is locked by a spring latch / located at the side of the car (fig. 4 and 3) located in the cage d (fng. 4) under the hook.

3. The application of the tackle of the coupling head, described in paragraph 1, in which (Fig. 5) the coupling arm "i" is gripped between the hook C and the hook, which has been retracted by the corresponding recess in the holder X of the device. , figs. 5. FIG.
