I claim 1. In a car-coupling, the combination of the draw-bar provided with a hooked draw-head,

a swinging point pivoted to said draw-head and adapted to be swung in front thereof to form a pointed hooked coupling or to one side thereof to permit the coupling of said drawhead with a twin-jaw coupling, and means for holding said swinging point in either position, substantially as described.

2. In 'a car-coupling, the combination of the draw-bar provided with a hooked draw-head recessed in its front end and having a pinhole and pin, and a swinging point pivoted to said draw-head and adapted to be swung in front thereof to form a pointed hooked coupling or to one side thereof to permit the coupling of said draw-head with a link, substantially as described.

8. In a car-coupling, the combination of a draw-bar, a hooked draw-head provided with a recess in its front end and a vertical pin passing through said recess, perforated lugs opposite the hooked portion of the draw-head, a swinging point provided with a Verticallyarranged and flattened shank pivotally secured between said lugs and a perforated lug adapted to enter the recess in the draw-head and be held therein by the said pin, and the flat spring for yieldingly holding the point when turned in either position, substantially as described.

4. In a car-coupling, the combination of the draw-bar, the draw-head, the pivoted swinging point provided with the verticallypivoted shank flattened at its sides, and the flat spring fixed to the draw-bar and yieldingly bearing against said pivoted shank, substantially as described.

5. In a car-coupling, the combination of the draw-bar, the draw-head provided at its front end with a recess and the vertical pin-hole,

' and the pivoted swinging point provided with the perforated lug adapted to enter said recess and be secured therein by means of a pm, substantially as described.
