The supporting casting also has a ing A. Each spring is disposed within the corvertical rear wall 19, which forms the end Wall responding casing 16 and comprises inner and sections of the casings 16-16. The wall 19 is outer coils having their opposite ends bearing respectively on the rear wall of the corresponding casing and the front wall of the cap B.

In the operation of my improved buffer, the bufiing force is transmitted to the outer face of the cap B, thereby forcing the cap inwardly toward the end of the car and compressing the springs C-C. Inward movement of the cap is limited by engagement of the wall 28 with the front ends of the casings 16-16.. When the cap is returned to its-normal position by the expansive action of the springs C-C, movement of the cap is limited by the pins 32-32 engaging the front ends of the guideways 25-25 of the, casting A. When the car is being operated on straight track, the pins 32. 32. of. the buffingcap B are guided along the outer walls 27'-27 of the guideways 25-25. When the bufiing cap B is swung to either side of the centered position dill? g ing a buffing action, the pins 32-32 will be correspondingly displaced, this displacement of the pins being permitted by the width of the guide-5 ways 25.25.

I have herein shown and described what I now consider the preferred manner of carrying out my invention, but the same is merely illustrative and I contemplate all changes and modifications that come within the scope of the claims appended hereto.

I claim:

1. In a buffer for railway cars, the combination with a support fixed to the end of the car, said support having forwardly projecting spring casings formed integral therewith, each of said casings having a flat top Wall and a lateral enlargement on the inner side thereof, said enlargement being longitudinally slotted; of a transversely disposed buifing head having an outer buifing face and a horizontal top wall, said top wall being slidingly supported on the top walls of said casings; spaced guide pins fixed to said top wall of the buffing head, said pins extending through the slots of the enlargements of the casings; and springs within said casings yieldingly opposing inward movement of the buifing head.

2. In a buffer for railway cars, the combination with a support fixed to the end of the car, said support having forwardly projecting, spaced casings connected at their inner ends by a transverse web, each Casing having a fiat top Wall; of a buffing cap having a transverse front wall and spaced rearwardly projecting, top and bottom walls, said front wall having an outer bufiing surface, said cap being telescoped over the outer ends of said casings and having the top wall thereof slidingly supported on the top walls of the casings; springs within said casings opposing inward movement of the buffing cap; and means for connecting said cap to the support, comprising laterally spaced pins extending through the top and bottom walls of the buffing cap, and guideways on said casings respectively, in which the pins are guided.

HARVEY J. LOUNSBURY.
