SU20118A1 - Automatic coupling for railway cars - Google Patents

Description

 automatic coupling of railway cars, the coupling device is supplied with a pivoting hook mounted in a working position by pressure on the neg® from the bottom of a curved tongue lifted by the tension force of the coil spring, when the tongue is released from engagement, with a tooth deflected by pressing it on the loop side of the opposite car.

In FIG. Figure 1 shows a partial longitudinal section of the coupling device in the disengaged state; FIG. 2 - the same, in a linked state.

On the end part A of the car, the guide frame is fixedly fixed, carrying in itself the ends of the axes M and F, of which the axis X can freely rotate relative to the frame J together with rigidly fastened with it. A tongue hook -B, which is used for coupling to the loop E of the opposite carriage, is freely connected to the tongue G, and to the axis F fixedly fixed in the frame B. The M axis in the inoperative position of the device (Fig. 1) is under pressure from the coil springs D, which tend to turn this axis and lift up the tongue upwards. In the same off position of the instrument tongue G with its protrusion in the upper part of the rear side

in engagement with the tooth T on the vertical part. The VT supported by the side projection L on the upper surface of the side branches of the frame B is under the influence of the spring K. To hold a part of the SL.T from lateral displacements, the frame P with a curved edge I is hinged through the axis C on the stationary part A of the car and limited in its downward rotation by abutting its rear branch into part A. The catenary loop E is fixed on the axis F and. supported, horizontally supported by a resistant J. For uncoupling the devices, the M axes are extended to the sides of the car and rotated manually with a key or lever worn on the end of the axis -M. To secure the device in an inoperative position, the cam // is connected to the axis M with a protrusion that can be in contact with the corresponding protrusion of the lever P freely rotated by hand on the axis installed in frame B.

When coupling the cars K, resting against the protrusions L-L and compressing the spring K, removes the tooth T from engagement with the protrusion on the tongue G, the last action of the spring D will rotate and force hook C

to engage with the loop E (Fig. 2), keeping it in a horizontal position, which also contributes to the friction between the end of the hook and the bent end, 1Tsom I frame R. For uncoupling cars it is necessary to turn the steering axle M, from which the tongue hook B goes down and tooth T goes over the protrusion on the tongue G.

The subject of the patent.

1. An automatic hitch for railway cars, characterized using a tongue tongue tightly attached to the axis, holding it in an inclined position with a tooth T, overhanging the tongue and lifted upwards by the spring D when the opposite car is pressed on tooth 1, which tongue is designed. lift the drawbar with a spring D, in order to grip the hinge of the opposite car, and keep it in a horizontal position throughout the engagement. 2. The form of implementation of the hitch described in clause 1, characterized in that the propeller Hg is used to hold the hinge in a horizontal position.
