CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 643,661, dated February 20, 1900.

Application filed June 71 1897. Renewed July 17, 1899. Serial No. 724,137. (No model.)

To all whom it may concern:

Beit known that I,- EMIL KRINNER, a subject of the German Emperor, residing at Munich, Germany, have invented an Improved Car- Coupling, of which the following is a specification.

This invention relates to an automatic carcoupling of simple construction which while closing will set the uncoupling-levers into their proper position.

The coupling may be opened from both sides of the cars, cannot become accidentally opened, and permits the cars to be drawn together, though insuring the proper distance between the buffers of freight-cars. It may be applied to cars of every description and can be used for cars with long, short, or unequal bufiers.

In the accompanying drawings, Figure 1 is a plan of the coupling, showing the general ar-,

rangement. Fig. 2 is a plan of the couplingheads; Fig. 3, a side View of Fig. 2; Fig. 4, a detail of the coupling-jaw; Fig. 5, a plan of part of the coupling; Fig. 6, a side view thereof; Fig. 7, a detail of spring a, and Fig. 8 a detail of lever e and its guide 0.

The letters a represent the sheet-metal casings of the coupling, and b are the couplingjaws pivoted thereto at b. When the couplin gs are brought together, the jaws pass each other sidewise by swinging inward, so as to be first brought into the position shown at b in Fig. 2. A pin 0 011 a rearward extension of each jaw will during this motion bear against a toggle or compound lever d, connected to sliding bar e, and thus draw this bar outward, as indicated by full lines, Fig; 2. The car-buffers will by their rebound now bring the jaws I) together, so that they engage one another (full lines, Fig. 2) and close the coupling, the jaws being prevented from swinging beyond their locking position by means of a roller f, pivoted to the rearward extension of the jaw and bearing against a squared edge of bar e. At its opposite edge the bar 6 will by roller f be pressed against a second roller g, turning on its own axis.

It will be seen that the bar e is not subjected to severe pressure, as the roller f will only hear momentarily against it after the hold the same in its central position and will i take up and reduce the shock when the coup lings are brought together.

The uncoupling is effected by hand-levers e engaging bars 6 and projecting toward both sides of the cars. These levers on being swung outward will withdraw bars e to liberate jaws b, with their rollers f, so that the jaws by the parting of the cars will be thrown into the position 17 Fig. 2.

In order to prevent the levers b from becoming accidentally displaced by the motion of the train, they are beveled inwardly and engaged by keepers 0, having inclined rests.

It will be seen that my improved coupling is automatic, safe, and can be manipulated with great facility.

What I claim is- 1. In a car-coupling, the combination of a coupling-jaw, with a roller pivoted thereto, a sliding bar engaged thereby, and with a toggle connected to the bar and adapted to be actuated by the jaw, substantially as specified.

2. In a car-coupling, the combination of a coupling-j aw having projections and recesses, with a roller pivoted to the jaw, a sliding bar engaged thereby, a toggle connected to the bar and adapted to be actuated by the jaw, a spring engaging the jaw, a hand-lever connected to the sliding bar, and a keeper engaging the hand-lever, substantially as specified.

In witness whereof I have hereunto set my hand in presence of two witnesses.

EMIL KRINNER.
