Abstract
An automatic coupling for streetcars and like vehicles comprises a connecting rod pivotally connected to the vehicle and a coupling head pivotally connected to the connecting rod. The coupling head is pivotally disposed in the horizontal plane between an operative position in an extension of the connecting rod, in which position the coupling head extends beyond the front profile of the vehicle, and an inoperative position beside the connecting rod, in which position the coupling head is located inside the front profile of the vehicle. The coupling head co-operates with a locking device, by means of which the coupling head may be locked to the connecting rod in the operative and inoperative positions.
Claims4
In an automatic coupling for streetcars and similar railborne vehicles, the coupling comprising:
- a. a connecting rod pivotally connected to the vehicle;
- and
- b. a coupling head pivotally connected to the connecting rod, the improvement that the coupling head is pivotal in the horizontal plane between an operative position in an extension of the connecting rod, in which position the coupling head projects beyond the front profile of the vehicle, and an inoperative position beside the connecting rod, in which position the coupling head is located inside the front profile of the vehicle;
- and that the coupling head cooperates with a locking device by means of which the coupling head may be locked to the connecting rod at least in said operative and inoperative positions;
- said locking device including a cone or the like which, in the locking positions, may be lodged in corresponding recesses;
- said cone being lodgably connected to a pin provided on said connecting rod or said coupling head, said pin extending through a groove in said coupling head or said connecting rod, said groove being curved and having the pivotal center of the coupling head as its center of curvature, and said groove being provided with said recesses corresponding to said locking positions.
