Suspension device for the coupling bracket of railway screw couplings. Patented in the German Empire on March 21, 1925.

Are two vehicles in railway operation by means of the known screw coupling connected, the coupling of one vehicle is hooked into the towing hook of the other, while the other Coupling is inserted into the safety hook of the opposite coupling. The latter connection is no longer required for air-braked trains because it is through the air brake when the clutch breaks

ment, both parts of the train are braked automatically. To now the free, no longer in The coupling hooked into the safety hook of the coupling opposite does not sag because it would then drag on the sleepers, one helps oneself with air-braked trains that one the coupling bracket of the free coupling in the hook that is hinged to the same towing hook a The safety coupling engages (Fig. 2). This process is because there are several parts at the same time are cumbersome to use and cause injuries.

This drawback is remedied by the subject matter of the invention.

In the drawing, Fig. 1 shows the device attached to a screw coupling. Fig. 2 shows the previously common type of suspension of the free screw coupling.

Fig. 3 and 4 show the suspension hook according to the invention in two views.

With the usual screw couplings, washers are pushed onto the bolts h screwed onto the coupling nut c and hold the associated coupling bracket b in position. According to the invention, one of these washers is replaced by a hook k which, however, is wider than the washer, and the split pin, which is otherwise located in front of the washer, therefore passes through bores in the hook eye. So that the cotter pin I enables the hook k to pivot on the bolt h in a vertical plane, the cotter pin bores are designed in the manner of an elongated hole (Figs. 3 and 4). When coupling two vehicles, the coupling bracket e of the free screw coupling is lifted by hand into the position shown in Fig. 1, the hook k being lifted from the bracket and pivoted up vertically by means of the slotted bores. When the bracket e is turned up further, the hook k automatically falls into the bracket (Fig. 1). This process involves only the movement of two relatively light parts and it is not necessary to lift the coupling as a whole.

Claims (1)

Patent claim: Suspension device for the coupling bracket of railway screw couplings, characterized in that a hook (k) which can be swiveled out in a vertical plane is placed on the bolt (h) of the coupling nut (c) of the screw coupling, in which the opened coupling bracket is hung when not in use.
