T0 all 'whom t 'may cof/wem:

Beit known that I, IRA O. WRIGHT, a citizen of the United States`,jresiding at the city of Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Draft Rigging; and I dov hereby declare the following to be a full,

and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to draft rigging for railway cars and, generally stated, consists of a center sill tie casting provided with stop members which latter a movable element` of the draft rigging gear is designed to engage- The principal feature of the present inrevision ofl a coinbined stop and tie casting connected to the s aced center sills, said casting having a p urality of bosses acting to space the castin wardly from said sills, said bosses also being arranged to receive the rivet lmeans for connecting the casting to the centersills. Another feature of my invention is to provide a combined center sill tie and stop member of maximum strength value for the amount of lmaterial used, the bosses Yformed on said member being advantageously disposed for firmly. connecting the casting to the sills in effectively resisting the forces to whichthe' car underframe is' subjected.

A vfurther feature of the invention is to provide strong and durable means for transmitting the bu'ing and draft strains to the center sills, said` means including center ller and stop members inwardl spaced from the center sills and arrange for-engagement by the respective forward andv casting.

Other ob'ects `virillbe obvius'from the def yscription ta en with the drawings chosen forr g ranged 12, lboth grou s of said bein vformed in al,A wit the side walls of t e casting an being provided with a` plurality-'0f spalline! thrwsh whichv pass 1 rigging associated vwith spacedbetween which latter are located front and rear Acenter filler and stop castings constructed in accordance with my invention.

Figure 2 is a central vertical longitudinal sectional view on the line 2 2 of Figure l, parts thereof being shown in elevation.

Figure 3 is a plan view of a draft rigging with the yoke and cushioning mechanism reversely of the car underframe on either side` thereof the bolster 2. The center plate yis shown at 3, said plate being connected by rivets. to the bottom flanges of the center sills and to the members constituting the bolster. A center bearing is arranged beneath the plate 3 and is provided with an,

opening through which the king'bolts extend into the center thimble. 4 formed iiitegral with the center sill tie and stop member 5. A cover plate is shown at 6 and the end sill of the car underframe at 7 the latter .being connected by rivets to the cover plate and upper flanges of the center sills, as shown,

The stop member 5 comprises a combined center liller, tie and stop casting connected to the draft sills by means of the rivets 8. Stop Ylugs 9 are provided on said member and are adapted to be engaged .by the rear follower 10 of the cushioning mechanism, the latter beingdiagrammatically shown in dot 'and 'dash lines, as indicated `in Figure 2.

The ymeans for spacing the stop casting 6 inwardly of the center sills and at the same time providing for its firm connection thereto,r consists of 'a series of longitudinally disposed 11, and other vertically arthe rivets 8. The engaging faces of the bosses firmly abut against the inner faces of the draft sills, and the relative depth of said bosses determines the spacing of the stop casting inwardly from the sills, as will be understood. The stop members or lugs 9 cooperating with the rear follower 10, are each reinforced by webs or flanges 13 pro jecting inwardly from the side walls 14 and forwardly of the casting, said flanges acting to brace the stops. I have located'the majority of the bosses 11 longitudinally of the casting and at points preferably between the inwardly projecting reinforcing flanges 13 so as to permit of the convenient insertion of the rivet connecting means, and to also advantageously obtain the additional reinforcing values of the bosses immediately' adjacent the flanges 13. The vertical bosses 12 are preferably arranged at or near the rear of the stop being vertical y arranged from the longitudinal rows through the bosses 11.

as distinguished of rivets passing The bosses are all preferably of uniform depth suihcient to provide for the advantageous inward spaclng of the stop lugs 9 from the center sills., rlhe longitudinally disposed bosses 11 are relatively long, each boss extending from substantially the operative face or' the stop lugs to` a point well back and over the licor portion o the casting.

Coo eratively associated with and arrange between the inner faces of the draft sills and the outer faces oi the wall portions 14 of the stop casting is a reinforcing means composed of an angle bar 15, the vertical llange 16 thereof extending upwardly between the inner face of the center sill and the oiset portion of the wall of the stop member, and a horizontal flange 17 of said angle bar projecting beneath an otiset ortion formed in the door of the sto casting. The angle bar extends the entire length of the stop member, and is preferably designed to continue rearwardly of the center sills. llhe horizontal flange 17 is cut away at an angle, as indicated at 18, thereby pro- Viding for the necessary clearance for thc rear end of the yoke extending between the stop lugs 9. The rivets 8 of the lowermost row pass through the reinforcing bar 15 and firmly unite the walls of the stop member with the center sills.

A similarly reinforced stop member 19 is connected by means of rivets 20 to the forward ends of the draft sills, said member including the striking casting 21 and the carr iron support 22. The forward end of t e draft rigging recess is closed bythe stop castin 19, which serves to :firmly connect the dg draft rigging. The vertical walls of the Stop member 19 ferm cheek plates 23, the

rear faces thereof providing stop lugs 24 casting, the attaching rivets raft sills at this point of the Maasai with which the forward follower, 25 of the cushioning mechanism is designed to engage.` Bosses 26 are provided on the outerv faces of the cheek plates andere adapted to engage with the inner faces of the center sills, said bosses acting to space the yatop member inwardly of the sills, as shown. Rivets 20 rigidly connect the front stop member 19 to the center sills, said rivets passing through the bosses 26. The upper boss extends substantially the length of the casting and the lower boss terminatesback of the forward end of said upper boss, as shown, the rear ends of each boss being arranged in close proximity to the stop lugs 24 of the cheek plates :for reinorcing'the latter. The several portions forming the stop member 19 are all formed integral, thereby providing a one-piece or unitary member which can be easil connected te the forward ends of the dra t sills.

Each cheek larly the stop lug 24 formed thereon, isreinforced by means of a top web portion 28 extending from the striking casting tothe stop lug, the central portion of said web being partly cut away, as shown in Figure 1. A series of anges or webs 29 entend rearwardly of the casting uniting the side walls' with the stop lugs, the inner faces of said flanges being cut away` or inclined, as shown, to provide lateral clearance for the yoke head. Each cheek plate is provided with a relativelylong key slot 30, said slot regis tering with a similar slot 31 formed in each center sill. through said slots and is arranged to connect the coupler 33 with the forward end of the yoke 34. Slots 35 are provided in the wall portions of the hooded head of the yoke, thereby permitting relative movement of the key therein, but said slots are shorter than the slots in the cheek plates, as shown,

ln normal position of the draft rigging,

'the front edge ot'the coupler key 32 engages the forward end of the slots in the yoke head, the said key passin through the opening in the coupler whic latter closely enages said key, the position of the coupler ey in the respective slots 30 and lbeing bout iitermediate thereof, as shown in plate 19, and more particu-y A coupler key 82 extends lili) vne ' e cushioning mechanism of the draft gear includes the forward `follower 25 and the rear follower 10, beth of which are,

adapted to coo crate with vthe respective stop lugs provi ed on the s aced stop castings connecting the center sills at each end of the yoke. The respective front and rear stop castings are is, the spacing bosses act to uniformly and inwardly space respective stop lugs 9 `and 2e from the center sills, as shown.`- A draft rigging peehet :for eer underirames `conlongitudinally alined, that lti structed in accordance with my inventionconsists -of comparatively few parts and those of light weightlbut maximum strengthy value, my present association of tie and stopioning mechanism including follower members, stop castings connected to said center sills, and elongated means furnishing in creased cross-sectional areas of metal in the lines of greatest stress imparted to the rivet connections projecting from the castings and contacting the inner opposed faces of the center sills for spacing said castings in-` .Wardly thereof, said stop castings bridging the sills and being arranged respectively for engagement Aby said follower members withv themeans inwardly spacing the castings disposed in longitudinal alinement.
