serial No. 615,753.

To all whom t may concern Be it known that I, JAMES R. CAnnwnLL, a citizen of the United States, and resident o f Chicago, county of Cook, and State of Illi-t nois, have invented certain new and useful Improvements in Railway-Cars, of which the following is a specification, and which are illustrated in the accompanying drawings forming a part thereof.

The invention relates to improvements in railway cars, and has particular reference to the application thereto of draft and buffinof mechanism.

'llhe object of the invention is to increase the efficiency of devices of this character; and it. consists broadly in so constructing the car and the draft and bufling mechanism thereof that the draft appliance is housed between the end of the car and the transom or body bolster, and, while serving 1n part as the buiflng device, is supplemented as such by bufling mechanism located back of the transom and connected with the draft mechanism by means of a lunger or thrust bar which passes beyond t e transom.

The invention is capable of embodiment in various known types of cars, there being used, for the purpose of disclosing its character, a common form of friction draft mechanism.

In the accompanying drawings, Figure 1 is a det-ail plan of a railwa. car with the flooring removed, the draft si ls being shown partly 1n section; and Fig.l2 is a detail longitudinal section of the car, the draft and bufling mechanisms being shown partly in section and partly in elevation.

The end sill of a car is shown at 10; its drafts sills at 11, 12, and one of its transoms or holsters at 13. The coupler is shown at 14, and is provided with the usual tailstrap or yoke 15 which encircles the followers 16 17. The forward follower engages a pair of draft lugs 18 19, which are secured to the inner'faces of the sills 11, 12. Between the followers 16 and 17 there is located any suitable form of yielding ressure-absorbing dedevices comprising two pairs of triangular wedge-blocks 20, 21, and 22, 23, seated, respectively, against the adjacent faces of the followers 16, 17; a block 24, having obligue or wedging faces at each end for engaging the adjacent faces of each pair of the first-mentioned blocks; a pair of beveled plates 25, 26, bearing against the outer faces of the members of each pair of the first-named wed e-blocks; a bolt 27 extending transversely t irough the members 24, 25 and 26, and carrying upon each of its ends 4coiled springs 28, 29, which react between abutments 30, 31, adjacent the ends of the bar 13, and abutments 32, 33, sleeved upon the bar and bearing, respectively, upon the members 25, 26. The draft gear described is of the form shown in Patent No. 819,266, granted to me May 1st, 1906.

A buling appliance which may be and, as shown, is of the same character as the draft appliance, is located back of the transom or bolster 13 and comprises a forward and rearward follower 34, 35, the latter abutting against lugs 36, 37, secured to the sills 11, 12; triangular wedging blocks 38, 39, and 40, 41; a central wedglng member 42 coperating with both of such pairs of wedging blocks; beveled lates 43, 44, engaging the outer faces of allie several wedging blocks; the transverse bolt 45 passing through the members 42, 43, and 44; the springs 46, 47, carried by the bolt and reacting between outer abutments 48, 49, and inner abutments 5o, 51.

Interposed between the rearward follower 17 of the draft mechanism and forward follower 34 of the buiiing mechanism just described is a plunger or thrustbar 52, which, in the construction shown, passes through a transverse aperture 53 in the transom or bolster 13. The'forward end of the bar 52 may be su ported u on brackets 54, 55, secured to t e inner aces of the sills 11, 12, and is bifurcated, as shown at 56, to straddle the rear end of the yoke 15 and to allow backward movement thereof.

Upon the application of pullin stresses the follower 17 is drawn forwar against the resistance of the springs 28, 29, and the various wedges coperating therewith, the stresses being transmitted to the draft sills through the forward follower 16 and the lugs 18, 19. Upon the application of buffing stresses the coupler 14 is moved inwardly and forces back the forward follower 16 against the resistance of the springs 28, 29, and the various wedges coperatin therewith the stresses being transmitte through the rearward follower 17 to the bar 52, and through this bar and the buling mechanism to the draft sills. The buflin mechanism back of the transom may be, an

preferably is more owerful than the draft mechanism, and will) not yield to the lighter ressures which are resisted entirely by the orward gear,l After the draft gear has been completely compressed the buffing gear will begin to yield.

lt has been found impracticable heretofore, because of the contracted space between the end of the car and the transom or llO in shown and described, the ordinary draft mechanism, which heretofore has been relied upon for dlssipating,l the bufng stresses, may ne supplemented by a bufling mechanioaiae nism havingA sufficient resistance to prevent damage to the ears, even though the bufng stresses be much more severe than a draft mechanism can withstand.

ll claiin as my inventionln combination, a car having a body bolster, draft gear located between the end of the car and the bolster and comprising a follower, a coupler bar, and a yoke attached to the coupler bar and encircling the follower, bufhng gear located back of the bolster, and a thrust bar interposed between the draft and buiiing gears, the forward end of the thrust bar being bifurcated to inclose the yoke.
