etters To all whom 'it may concern.'

lle it known that I, (.imiinas M. EVANS, a citizen of the United States of America, and resident of Springfield, in the couiit of Hampden and State of Massachusetts, iave inventedcertain new and useful Improvements in Draw-Bar Mechanisms for Rail,L way-(Jars of which the following is a full, clear, anV exact description.

This invention relates to improvements in 'the means for acquiring the interlocking engagement of 'the draw bar of a railway cai' with the end portion of the underfran'ie or licor frame, with the object of readily enabling in a simple and practicableinanner, and with a view to cheapnessof construction, the connection and disconnectipnof the parts. t i I The invention is described in c'onjunction with the accompanying drawings, and is defined in the claims. t. v

In the4 drawings z-Figure l isa lan'view of the draw bar and a horizonte longitudinal.sectional viewof lower portions of. the floor frame with which it is engaged,'-I the plan formation of tl-ieA ortion of4 the under-frame which above tie parts in`seotion being represented bybroken lines.V Fig.

2 is a longitudinal sectional view as taken on line 2 2, Fig. I; Figs. `3 andl 4 4are cross sections taken respectively on linesB-, and 4--4, Fig. 1; Fig. 5 is a perspective view, for particularly showing,.in partially separated relations, the Vparte most prominently comprised .in the prent invention. Similar' characters of reference indicate corres )ending parts in all of th views.V

In tie drawings, A represents ille end 0r head po'rtion of a railwav car under rear portions thereof, and suitably far to' the -rear of the abutments 28, removable abut-. monts 30, 30, which, as shown, are constructed in the formof coisedout blocks .to disengage t eir dowels 33 4the sockets 34, and then the abutment blocks eliginnl a `plication for provided .with dowels, or inwardl p1^0jecting studs, 33, which have close tting engagements in sockets or inortises 34 in the portions 10 10, whichconstitu'te the vertical walls of thesaid longitudinally ranging, inwardl opening, channels.

The raw bar C centrally' horizontally and longitudinally disposed under the head vframe and having, its rear attenuated ex-V tremity between the inwardly 4openin mouths of the channels 25, 25, is extentie wardlv and rearwardly located buffer plates i' t e side ears or extensions 37, 3l, ofv

which laterally extend and fslidingly, fit in the opl ositelA located pockets 25, 25, the' fdrwar bu er plate havingthe forward surfaces of its extensions 37 in Contact against the permanent abutments 2 8, while the rearwardly located buffer plate normally rearwardly contacts b its extensions 'against the forward ends o Ithe removable utinents 3U, 30. The draw bar spring k is in compression as usual between the Vbuffer` plates/ 'df and the nut m forms the means of engagement, as common, between the; rear end o' shank of the draw bar and the rearward o e of the buffer plates.

-When it is desired to disconnect or take out the draw bar4 buffer.. plates,-thedraw bar being disconnected therefrom,'the bolts 36 are removed, the abutment blocks 30, 30,

are forced sli htly transversev inwardly om within are slid longitudinally rearwardly along, and` out frtiratlhe rear open ends of. the pockets, thereh leaving no impediment tp the rearward siding, for removal of either or both of the buffer plates...

described in )n 908, Serial 6,6 through the apertnred separated and for-4 No. 4415.523, although the application"tuffi` the present 'drawbnr mechanism is 1n ndi manner to be understood' as confined to ein;` b
