In bufiing the action is similar, except that the strain is transmitted through the block 7 directly to one of the followerplates, while the other follower-plate engages the stop-lugs or abutments 4:, the slots 8 be ing long enough to allow a sufficient free movement of the ends of the straps.

Heretofore it has been the practice to employ two sets of draft and buffing mechanism on a car, one set being placed at each end; but by means of my improved connections a single mechanism of this type may be utilized to take up the shocks and resist the strains due to draft and bufiing from either or both ends of the car, thus saving great expense in the equipment.

Having now described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. In a draw-gear and buffing apparatus, the combination with the draw-heads and a yielding draft and bufling mechanism for transmitting stresses to the car-frame, of intermediate independent connections adapted to transmit the draft and bufling strains from either end of the car to said draft and buffing mechanism.

2. In adraw-gear and buffingapparatus for cars, the combination with a draw-head at each end of the car and a yielding resistance mechanism for transmitting stresses to the car-frame, of independent means connecting each draw-head with the yielding resistance mechanism and adapted to transmit draft and bufling strains from either end of the car axially to said mechanism.

3. In a draw-gear and buffing apparatus, the combination with a yielding resistance mechanism and follower-plates for transmitting stresses to the car-frame, of a draw-bar at each end of the car and an independent connection from each draw-bar engaging one of the follower-plates.

4:. The combination on a car, of a yielding resistance member, follower-plates therefor,

a draw-bar at each end of the car and a strap secured to each draw-bar and passing around the follower-plates.

5. In a draw-gear, the combination with a draw-bar at each end of the car and a yielding resistance mechanism for transmitting stresses to the car-frame, of independent means connecting each draw-bar with the yielding resistance mechanism and adapted to transmit draft strains from either draw-bar to said mechanism.

6. In a draw-gear, the combination of a yielding resistance member, a draw-bar at each end of the car, and a strap secured to each draw-bar, each strap passing through the other and around the yielding resistance member.

7. In a draw-gear, the combination of a yielding resistance member, a draw-bar at each end of the car, and a strap secured to each draw-bar and passing around the yielding resistance member, the plane of each strap being inclined to the vertical.

8. In a draw-gear, the combination with a draw-barat each end of the car, a yielding re sistance mechanism and follower-plates therefor, of slotted buiiing-blocks connected to the draw-bars for engaging the follower-plates, and a strap secured to each draw-bar and extending into the slot of the opposite bufiingblock.

9. In a draw-gear, the combination with a draw-bar at each end of the car, a yielding re sistance mechanism, and means for transmitting the draft and bufling stresses from the yielding resistance mechanism to the carframe, of independent means connecting each draw-bar with the yielding resistance mechanism and adapted to transmit stresses from either draw-bar to said mechanism.

10. In a draw-gear, the combination with abutments secured to the car-frame, followerplates engaging said abutments, and a yielding resistance mechanism located between the follower-plates, of a draw-bar at each end of the car, and independent means connecting each draw-bar with the yielding resistance mechanism and adapted to transmit stresses from either draw-bar to said mechanism.

In testimony whereof I have hereunto set my hand.
