To all whom may concern Ee it known that i, CHARLES E. DA'rH, a

citizen of the United States, residing at Chicago, in the county ot Cook and State or" illinois, have invented a certain new and useful lmprovement'in Railway Draftills, of which the following isa full, clear, concise, and exact description, reference being had to the accompanying drawings, torming a part oi this specification.

- My invention .relates to an improvement in draft-sills for railway cars.

@ne object of my invention is to provide iii-sills ot' simple, elicient and strong l5 constfucon; and a iurtherobject is to provide draft-sills that maybe readily applieol to railway cars haring wooden under.A

iframes.

ini/e -tion is fully describe in the speciiication, and sli wn in tbe accompany inf' drawings, in wliicb- Figure is el top ple-n View oi (irait-sills secured to center-sills and embodying my invention; Fig. 2 is a vertical longitudinal 25 section on line 2 2 of Fig. l', Fig. 3 is a crcsfsection on line 3-3 of Fig. 2; Fig. fi is a cross-section on line LiL-4 of Fig. 2; enel Fig. is a cross-section on line 5 5 oi Fig.

Referring to the drawings, the numerals 6-6 represent center-sills of an ordinary car frame; 7 the floor of the oar; 8 the end sill; 9 the buiier block; l0 the body bolster provided with the upper/Hange l1; 12 the lower flange, and having on its lower fece the recess 13 to receive the boss of the truck cent-er pla-te, the/,said bolster being also provided with the vertical opening M to receive a pin. rThe foregoing parte ere 4@ of well known construction. in the forni of bolster shown in the drawings, the bodybolster center plate is made integral with y e bolster. The draft-arms 16 are two in number for each end of the car, each being.

adapted for attachment to a center-sill. As the drafterms at either end of the cer are counterparts of eachother, we will describe oneoi saicl arms. inn preferable construction, each oi arms consists of a forward portion i?, and -a rearward portion 18. The forwar` portion 17 is provided with 'the stop-shoulrlers i9, 2O and 2l, which are `ipreierbly integral with the member 17,- and serve their nenal function in tbe (irait rigging for the cer.A The member l? is orcvided with a preferably integral horn 22, adapted to vengage against the end-sill 8, as indicated at the numeral 23 in Fig. 2 of the drawings. The( said member l? is forwardly extended' to the forwtird face 2i of the bu'er bloclrgl, and at its lrearward end @buts against the front iace 25ct the bo iybolster 10. "lin l preferable construction bolt 25 is passed through the butter block 9 and tbe'member l? of the draft-erin the drawbar carry "non 2i'. A bolt 28 secures the member to the end-sill 8, suitable bolts 29-29 secure the member i? to tb. centeresill 8. Each member if( is providled 'with :in upper flange 30, eclapteai to engage the under face 3i of a center-sill 6, enel with o lower flange 32 and intermeiate such flanges with a longitudine] strengthening web 33.- Each member 18 is in 'preferable construction Xsbape in cross section, the lower fiane'e 3e converging np- I y toward. the upper flange 'Jibe te* verri erige 36 of member i8 en against the rear face oi the body-bolster, inrlicaterl et the moral 37 in Fig. i .the drawings. 'l ie member i8 is Vsuitably secured to the adje,- cent center-sill 6 preferably by bolts 38e-38 passing through the center-sill anol through ways 39-39vertically provided in the meniber i8. rlhe member 18 is connecterl to tbe member 17 on each draft-sill by means passing both above and below`vthe body-bolster- The means passing above the body-bolster preferably consists of a channel bar 4G. preferably integral with the member 18 anti .secured to the upper flange 3G of the ineinber 17 by suitable means, preferably the rivets LiL-41. The means connecting the member 18 to the member 17 passing un.- derneath the body-bolster consists kpreferably of a bar 42 formed integrally with the member 18, suitably secured to the lower flange 32 of the member l?, prei'erablyby the rivets 43-43, the saicl bar being of snitable conformation to pass around tbe bodybolster center plate l5. Bolts may be employed to pass through the arm f-l-O and engage the bolster at one end and the adjacent center-sill at the other.

lt will be observe that in the construction described pulling snol buibng stressesu are transmitted directly in a. horizontal through tbe bolster, and that aii unusually strong union of bolster and draft-arms is secured.

' clearance As clearly shown m Fig. 1 of the drawing, the member 17 is located mostly on the me ner side of the wooden center sills and the portion 18 is off-set oiitwardlyas it passes the bolster in.' order to provide sufficient for tbe portion of the bolster forming the socket or the king pito. lt 'will also be observed 'tliat the portions t() and l2 of the member i8, being 'formed integrally with the latter, constitute a forli wliiob straddles tbe bolster and. the ends of the portions forming the fork are secured to the member 17, tlius forming ari unusually rigid and substantial oiistriiotion.

I claim:

1. ln a oar imderiarriirig7 the combination with wooden center sills and bodiT bolster, of a draft arm secured to tbe wooden.

sills, said draft arm comprising; a forward member serving as a stop of a draft rigging and a rearward member ooimeoted to tbe forward member, the rearward member having integral fork arms between wliieb the body bolster is arranged.

2. le eiiderramirig for railway cars, the combination 'with wooden sills and a body bolster, of a draft arm comprising a front and a rear member, the front member being located mostly to the inner side of the eenter sill aiid the rear member being off-set outwardly from the i'rorit member where it passes tbe bolster, the bolster passing through said draft arm.

- 3. ln iiiiderframiiig for railway cars, the combination with center sills and body1 bolster, of a draft arm secured to each sill, eaob draft arm eoiriprisiiig a iront member the rear of which abats the body bolster and a rear member having integral extensions dbltlebdlt` passing above an e ow tie o y boils ei and forming a fork between which the bolster is iriourited7 the ends of said extensions being; secured to the front member of the draft arm, the lower member of said fork being outwardly' oset where it passes the body bolster.
