To 521 whom it may concern: I

Be it'known that we, CHARLES T. WEST- LAKE and CHARLES F. FREDE, citizens of the United States, residing at St. Louis,"-M1ssouri, have invented a certain new and useful Improvement in Bufiing Mechanism for Car- Plat-forms, of which. the following is a full, clear, and exact description, such as Wlll enable others. skilled in the art towhich it 'appertains to'make and'use the same, reference being-had to the accompanying drawings, forming part of-this specification, in which- I '1 Figure 1 is a top plan. view of a cast metal platform with portions'fof the,bufier beam "and end sill and showing the bufling mechanism in position thereon. Fig-2 is a longitudinal section taken approximately on the line 2-2 of Fig. 1 Fig; 3 is an enlarged section taken on theline 33 .of F ig. 1. Fig; l is :alt'ra-nsverse section .taken on the line 4-'4 of Fig.1. f

This, invention relates generally to improveme'nts in railway c'a'r platform coni 7 ing mechani'smapplied to cast metal plat-- forms, such as are now in general use 1n passtruction and more particularly to the buffsenger car construction, and the principal obj ects of the invention skeleton platform. and buffer beam so that a form of' bufiing mechanism of accepted M. C. B. type and'n'ow'in use on a number ofpassenger' cars may be readily applied to said platform and buffer beam and, further,

to provide a construction wherein the operating parts of the bufling mechanism can readily be placed in or removed from posi-, tion without detaching the vestibule orbuffer from its stems, therebypermitting the bufling mechanismtobe easily and.

quickly repaired when any of the operating parts have become broken or .unfit for service, I

With the-above objects in View, our invention consists in certain novel features of construction and arrangements of parts hereinafter more fully described and claimed.

Referring in' detail to the accompanying drawings: 1 designates the end sill of a cast metal car under frame of the-type now in general use and formed integral with and projecting forwardly therefrom is a series 7 of vertically disposed webs 2 and horizonare: to construct a bufi'er beam.

tallydisposed plates 3, which form a skeleton platform, Formed: integral with the forward end of this-skeleton platform is a buffer beam'4 of the 'iisual box shape and positioned on top of the central portion of said beam'fis a threshold "plate 5.

The numeral 6 designates a bufling member of the usual form 'which occupies a position'immediately in front of the bulfer beam,

and positionediontop this bufling member is a plate? which is adapted to. slide beneath the plate 5. The buffer 6 is carried upon the forward ends of a pair of side'bufit'er stems 7 and the central portion of said buflei' bears against the forward .end of a centerbufiing -stem 8. .Allof the buffer stems are arranged to slide freely through corresponding openings 9 formed in the front and rear walls of the buffer beam 4.

The numeral 2 webs which occupy platform," and formed integral with .the

upper edges of these 'websis a horizontally disposed plate 3 ,Formed'integral with the webs and with the plate 3 is a transversely disposedwall 10, through which is designates thepair of positions on oppositesides of the transverse center of the skeleton formed an opening-11, which is in .alinement with the center bufie'rstem openings in the The forward-portion ofthe-center bufier stem 8 is preferably square or non-circular in cross-section and the rear portion of the said stem is preferably round in cross-seci tion, and positioned against the shoulder be-' tween the rounded rear portion'and the square 12. 'A"'r ear follower plate 13 is positioned on the-rounded rear portion 'of'the center stem and normally bears against the transverse wall '10, and mounted on'the rounded posed between t he plates 12 and 13 is a comparativel'y heavy coil '5 end ofthe jcenter bu er stem 8 operates through the openingll in the transverse wall 10,- and' a pm or key 15 is inserted latform to the '90 forward portion, is a'di'sk or follower plate rear portion of'the centerstem and interringl4, The rear the collars 1 8 and mounted on said rear ends, are nuts 19. The forward portions of the side buffer stems 7 are preferably square or non-circular in cross-section and the rear portions. are round in cross-section.

Ada ted to bear against the shoulders forme between the square or non-circular forward portions and the round rear portions of these side stems, are disks or follower plates 20, and bearing against said plates are the forward ends of-side bufier stem springs '21-, therear ends of which bear against the forward ends of the 001 his 18.

Under normal conditions, the butter springs 21 and 14 maintain the buffer 6 at its outward limit .of movement, and when said buffer is moved inward toward the beam 4, during the coupling of two cars,

said springs will be compressed andwill be therefore simultaneously thrown into action to yieldingly resist the inward movement of the bufier and buffing mechanism, until said parts have been moved to such a degree as to permit the coupling of the cars.

The buffer stems are mounted to move freely through their bearings and the springs mounted on said bufi'er stems readily combine. to yieldin ly resist any inward movement of the bu er.

The construction herein described is comparatively ,simple, provides a strong and said construct-ion is especially advantageo'us when it is necessary to make repairs or to'renew any parts which have become worn or broken inv service.

It will be readily understood that minor changes in the size, form and construction of the various parts of our improved bufling mechanism, can be made and substituted for those herein shown and described without departing from the spirit ofour invention, the. scope of which is set forth in the appended claim;

'In a bufiing .mechanismof the class described, the combination with a car end sill and buffer beam, of a skeleton platform integral with said end sill and buffer beam, which platform comprises aseries of longitudinally disposed members which are T- shape in cross section, a series of transversely disposed webs arranged between said longitudinally disposed "members, and bearings formed in said transversely disposed webs for the'rear portions of the center and side bufler stems.

In testimony whereof we here unto aflix our signatures in the presence oftwo witnesses, this 28th day of October, 1911, I
