DRAFT RIQGING.
i Application filed January 13, 1923. Serial No. 612,451..
which extend continuously from side to side of the washer and are adapted 'to engage the draft sills.- These washers have been secured to draft keys by means of a single or a plurality oi securing members, which in some cases pass through the washers and keys and in other cases pass'through the keys only, the -ou'ter surfaces ofthe washers in these latter cases only 'contacting with the secur-l ing members. When a washer ot this type is secured t0 a draft 'key by a plurality ot sesuring members which pass through the washer and through the key, it will be noted that when such key has been moved at an angle to the draft sill, the side portion of the washer adjacent one ofthe longitudinal edges of the key, will engage the sill, and
will thus orm a leverage which causes severe shearing stresses in one direction, on one of the securing members and at the same time causes'similar shearing stresses in the opposite direction on the other securing member. It will also be noted that when a draft'key having a washer of the ty just described secured thereto by means ofp; plurality of members which pass through the key only, is moved at an angle to the sill, the entire shearing stresses will come upon one of these securing members only. It is an object ofthis invention to provide a draft key washer which will eliminate the above objectionable features.
Referrin to the drawings in which like reference caracters refer to like parts, Figure 1 is a sectional plan viewof aportion of a railway car with the invention mounted thereon.' Fig. 2 is a side elevational view of the same; Fig. 3 is a sectional view of the same taken on the line 3-3 ofFig. 2 and FigJ/i is a'plan view of a modification of the manner of securing the draft key washer.
Referring now in detail to the drawing, the reference character 1 indicates the dra t sill or center sill of a railway car, which may be ofvany suitable construction, and which is illustrated in the drawing as comprising spaced channel members 2 suitably connected together.
Between the members 2 a draft rigging is mounted, which comprises a shock absorb# ing device 3 and yoke 4, and a coupler 6. The shank ot' this coupler extends into a jaw 8 formed in the outerend portion of the yoke and is connected with such jaw portion and sills by means of a transverse key member f), which passes through openings formed in the sill members '2, jaw. portion 8 of the yoke and shank 7. The key i) is ot greater length than the distance-between the webs of the sill members 2 ani when in operativeposition, extends beyond such webs. One end of this key is provided with a washer l0 which preferably surrounds the key and is secured thereto, preferably by a U-shaped member 11, both legs of which extend through the two thicknesses of the washer and the key, which legs at their lower ends are so bent that the member will be held against accidental loss. This washer is of great-er width at its central portion than at its side portions, and is provided with an inwardly extending .projection 12, the sides of which slope fromfeach side of the washer toward the sill, the apex or inner bearing surface 13 of such projection'being located intermediate the side edges of the key, and adapted to engave the sill or a member 14 secured to the sill when the key is moved at an angle to the sill, as shown in dot and dash lines in Fig. 1, and when the key is moved at right angles to the sill from its normal operative position shown in 'full lines in this figure. It will be noted that as the vapex 13 of the projection 12 is at substan-v tially the longitudinal center line of the key and the legs of the securing members are arran ed on both sides of such center line, any s earing stresses caused by the Washer engaging the sill or member 14 will be transmitted to both of the le s of the securing member equally. Inste'a of engaging the sill or member 414 the washer 10 may engage the cheek plates 15. This may be doneV by eliminating the member 14 and so forming the cheek plates that a portion ,thereof will extend through the opening formed in the sills for the reception of the key.l It will be understood that instead of making titl on, u
the projection l2 of the Washer l0 of the sliepe just described, it may loe mede o any other suitable shape loy which the shearing stresses caused by the washer engaging the sills or tlie member-1l will loe transmitted centrally of the Wsslier to the Washer seemn ing ineens.
The opposite end portion oi this key is 'provided with` en integial head poition 1G, tlie inwardly extending projection of which is preferably of the saine shape es the pio" jection l2 of the wssliei' 10. lf desired, this integinl heed may be omitted, end both ends of the key pioyided with *o Weslier l0.
Jln Figline 4, o inodiicetion of the invention lios been illustrated, in which tlfie washer l() is secured to tliekey loy ineens oil a: U- slniped inernloer, which posses through tlie key only, end forms on abutment tor'tlie washer, The operation of this Woslici' is substantially the some ostlie wesliei' just described, A
lt will loe apparent to those skilled in the sift to which this invention apperteins that changes may lie inode in the e'i'engeinent and form oil Vthe details of the invention witliout departingijl from the spirit end scope of the appended claims.
Hoving thus described the invention., Wlint l ele-im es new and desire to secure lay liettens'Potent is zm l. The combination lwith a sill of o ruilway cui, of draft rigging associated tlierewith, said rigging comprising :L key extending beyond seid sill and movable :it different angles thereto, end lli-shaped means on seid key adopted to engage said sill whereby the stresses set np longitudinally of seid key ere Leimen f stifesses set un lon-gitudinelly of seid key nel gsidlcss of the angeles position are trainsniitted centrally of seidiwasliei.
3. The combination with -di'eilt sills of :1 i-eilwey een, of draft rigging mounted' thei'eon, said. rigging comprising4 a key adapted to essnine dill'eient angular positions relative to seid sills, and projections on seid key adapted to engage seid sills, sind apply centinlly tliei'eoi stijesses set up longitudinally lie position oil seid fl. rllie combination with o droit sill of o ioilnfoy con, of eli-oft nigging associated tlieiewitli, seid nigging coinpiisingg,n o key, and .ineens on seid key having' veiticelly aligned spices adapted to engage seid sill.
