DRAF'E-.EEGGING FOR RAILWAY-CAM.

' To all 'whom it may' concern:

Beit known that I, 'ADAM WAGKMAN, a

for railway cars,.n.ore especially the draftV Louis, tate of Missouri, have invented a new and useful Draft-Rigging for lRailway- Cars, of which the following 'is especification.

The invention relates to Vimprovements in draft rigging for railway cars.

The object of the present invention is to improve the construction of draft rigging rigging shown and described in Patent No. 779,012, granted to ine dan. 3,'1905,'and to provide a simple and comparatively inex pensive draft rigging of increased strength and durability, adapted to. absorb the shocks `and minimize their eifect on the car, and thereby reduce the cost of repairs to a miniinuin.

A. furl her object of the invention is .to provide draft rigging of this character, equipped with frictional devices adapted .to

.irst retard and then finally check the inward or rearward movement of the draivbar to prevent the biitling spring or springs frombeing entirely-eoinpressedor deadened, thereby increasing the life and eiliciency of the same.

'Another object of the invention is to pro vide means for checking and limiting the outward or forward movement. of the draft mechanism to prevent the rear pulling spring or springs from-'entirely collapsingand becoming deadened and liable to frac- The invention also has for its objectv to i strengthen the draft rigging particularly at the center of the body bolster', and to provide a construction'adapted to admit of a bolster having a solid center.

ViTith these and other objects in view, the invention consists'in' the construction and novel combination of'parts hereinafter fully described, illustrated in the accompanying drawings, and pointed' ont in the claims hereto appended; it being understood that various changes in the form, propo rtion,size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.'

The body bolster l of the draft rigging, like that shown and described in the seid patent, consists preferably of :i single .integral casting, und is composed of a top plate or member 2, e bottoni plate or niem-A tion of the rear end of t front Wooden llller block 9 and a rear Wooden iller block 10. rlie front and rear vertical Webs are also provided for the Attachment of front and rear draft beams 1l and l2, secured to the said flanges 5 and G by transverse bolts 13 and 14, which also pierce the iller blocks. The body bolster l(1nd 'the front and rear draft, beams, which are rigidly connected together, ere bolted to the frame-work 15 of the vcer in the manner set forth in 'the seid patent, the draft beams being provided with suitable looltingl lianges end bosses 1G and 17, which are let into the sills. The inner or rear ends of the front draft beams are recessed .at i8, and are fitted into the space betweenitb up `1er and' lower plates or niembers'of tbe bo y bolster in advance ot" the central connecting web, and tlie .rontends ot' the rear draf-t beams are provided with corresponding recesses 19 to fit within the body bolster in rear of the central connecting web. This arranges the up er faces ot' the draft beams and the body bolster in flush relation, and the proximate ends of tbe front and rear draft beams are provided et the said recesses Witli'bolting flanges 20 and 21, secured to the inner face of the t J plate or member of the body bolster by bo te 22 and 23, which also pierce the adjacent sills for securing the bolster to the same. The front draft beams, which are spaced apart, toreceive the draw bar 2li of s coupler or..dr"w head 25, are recessed at the upper ortions of their front edge 26 to receive :i `liumper bloclf27,pmd are provided at their inner faces with Jfol-W:irdly or outwardly tapered approximately triangular enlargements 27, presenting inwardly or -rearwzirdly converging :ingnlnrly disposed sidix feces and adapted to be engaged by wedges and 29, located at opposite sides of the draw bei' sind tnpered inwardly or rearwardly end adapted to retard und check the inward or reni-Werd movementof the said drew bar to prevent injury to the boiling spring 30.

The draft rigging may bc equipped with one or more boiling springsfmid in practice, While bn'liing. n boiling spring' closes or conipresses aboutv three inches, and when lnlly oeefies compressed 'end deelden-ed' is liable to be broken. The wedge for producing friction nt the sides of the drew heed and the other devices hereinafter described for producing friction'are designed to first retard the inward movement of the drew bar end then finally check suoli movement tefore the bnling spring is fully closed br compressed, say witbin one-linlit an inch of complete comi pression. This will vprevent tne boiling spring from lbecoming deadened end will materially increase the life of such spring, and the friction devices also operate toebsorb the jzirs and shocks and minimize their edect on tire cer structure and reduce thel cost of repairs. A c

`Wlien the buiing spring is in its'normal condition, that is, neither distendednor compressed, there is sniiicient space between' the Wedges 28 end Q9 :ind the copersting surfaces to permit. the said inward more ment ofthe drew bar. This space admits of .e limited lateral movement of tbe drew bar,

which' lateral movement irxcrees 'as the drew ber is drown outward through tie 'distention of the boiling spring.

The Wedge 28', which is formed integral with the drew bead, consists of e substantially triangolari enlargement and 'presents :in inclined :ingnlarly disposed .tace to tlie adjacent enlargement or Wedge 27 ot the Y proximate draft. beam. The 'other side Wedge 29* consists o' n res-rwsrdlytpered front portion of e movable friction plate or member 31, located et the oppositefside of L the drew ber and providdwith e longitudinzil slot 32, through which asses a front cross head 33, which connects te front slotted ends 34 of e pair of draft rods 35. Tite draft rods 35 sire locatedet oppositesides of .the draft beams and on the exterior of the seme, and they are provided with rear slotted ends 36, which are connected byav ree'r cross heed 37. The trontcross heed 33 extends through

slots

38 and 39 of the drew bnr end the draft timbers, end when the draw heed is forced inwardly or rearwardly, it carries With it the front cross head and the slidable side plate or member 31. The slot 32 of the side plate or member per mits the letter to yield or stop While the drew ber moves inward or rearward independently of tbe said side plate or member,A so that tbe. drew bar will not become locked until the boiler spring is nearly compressed. rlhe arrangement of the slideble late or member 3l :it one side ot the. drew arend' the integral wedge nt the opposite side ofthe draw ber is preferred, but the side friction'on the drow bnr may be increased by nml/:ing botti of the movable Wedges 33ta integral with the drew ber, as illustrated in Figs. 2G and il? of the drawings, and e corresponding rednction oi? the side, 'friction may be obtained by constructing botti of the movable wedgeslb the `central sockets with slots eeaaea separate from and slidahle with' respect to the -drawban as shown in Fig. 25 of the drawings The terminals of the front and rear cross heads are reduced to form shoulders for engaging the slotted ends of the draft rods, which. are secured on the reduced ends of the cross heads. by means of front and rear keys 40 and-llllhe vertical web of the body bolster is provided at opposite sides of #l2 through which the draft rods pass.

The draw bar is equipped `at its rear end with a tail pin 43, piercing the rear end 'of the draw bar andfprovided with a head arranged Within the saine, but the tail pin may be Secured to the rear end of the draw bar in any preferred-manner. The tail pin, which is provided with arearwardly 'tapered or Wedge-shaped rear end all, extends rearwardly to the front or outer end of the front liller bloclr 9, which is reinforced at its front end by an angle metallic face plate 45, fitted against the upper face andl the front end of the filler block 9, as clearly illustrated in Fig. 1 of the drawings. The upper face of the said block 9 'is recessed to receive the upper portion of the angle face plate, which 1s arranged in flush relation with the top of the llller block? A. bottoni metallic face plate 46 is secured to the lower face of the front filler block and extends from the body bolster to the vertical, front portion of the angle face plate. The buffer spring 30, which is disposed on the tail pin, is interosed between the outer or front end of the iller block 9, and the rear end of the draft bar, a front follower l? being litted against the rear or inner endof the draw bar and the front or outer end of the buffer spring. The front follower L.t7 is composed .of two sides 48 and a front connecting transverse portion having a slot` 9, through which the tail pin passes. The lower edges 5() of the sides of the front follower are horixontal and slide upon horizontal guide and supporting flanges 5l, formed integral with the front draft beams and extending inwardly therefrom at the lower edge thereof, as clearly 'shown in Fig. ll of the drawings. T he upper edges 5'2 of the front portions of the sides areinelined down Yardly and rcar' Wardly and are arranged to frictionally engage downwardly and rearwardly inclined faces of upper longitudinal flanges 53, formed integral with the draft beams and taperedforwardly and reinforced by bracing ribs 54, also formed beams and located flanges in order to avoid wearing the lower inclined faces of the upper flanges 53,. the latter are equipped with springs llocated beneath and extendingl ofthe flanges 58 and having-their front ends 56 bent upon themselves to .form hook#y integral with the draft above the longitudinal longitudinally l shaped portions for engaging the front or 4outer ends of the upper flanges.

portions of the springs 55 are extended upwardly and are coiled or rolled to form eyes 57,v through which .passes a 'transverse bolt 58. The transverse bolt 58 pierces the frontdraft beams and supports a spacing sleeve 59, which is interposed between the eyes of the rearJ ends of the springs 55, as clearly shown in Fig. 7 of the drawings. The springs are removable and are adapted to be replaced by new springs when worn, and by subjecting the beams do not have to be discarded through wear of the flanges or enlargements. When the front follower'is moved rearwardly, the inclined upper edges engage the springs 55, creating friction and finally resulting in checking the inward or rearward movement of the draw bar.

T he rear or inner portions tapered side faces (3l, and are frictionallyengaged by the" laterally movable friction blocks or members 62, operating in a transverse reeess'tlaof the lower portion of the front end of the filler block The laterally movable friction blocks or members, which are tapered forwardly, are arranged in pairs, which are located at opposite sides of the tapered inner or rear end of the tail pin of the draw bar. Coiled springs G3 are interposed between the members of each pair of laterally movable friction blocks or members, which areprovidcd at their inner faces with integral studs (il, fitted within and braced by the end coils of the springs (SI-l, which are disposed transversely of the draft results in compressing the coiled springs (33 The rearV springs to the wear, the draft.

Y ,S5 (30 are l-aterall y to present inner angularly disposed of the laterally movable friction blocks or members Gland friction is ther-eb)v created to resist the inward or rearward movement of the draw head. The vertical portion of thc angle metallic face plate l5 isprovided with an opening 65 for the passage of the tail pin, and the front filler block l) is provided -in`thc rear vertical wall of the recess Qa'with a socket (3b, forming an extension or branch of the recess to provide a passage way for the tapered rear end of the tail pin. The walls of the recess 5) are reinforced by an angle wear plate (ST, composed of a horizontalland a vertical portion, the vertical1 portion Abeing provided with an opening (38, registering with the socket or extension (36 of the recess 9a.

The -front follower is provided at the top and bottom with slots (38" and (3), and it has forwardly o r outwardly converging inclined lips or flanges 70 and 1, disposed trans-V versely" of the follower and connected with Athe 'upper and lower edges of the transverse portion by spring bends( 46 of the filler block at slots or

openings

68 and 69 receive upper and lower longitudinal designed to be constructed of any desired strength and secured to the filler block at the to with ront engaging portions 76 and 7T, which are ta ered orwedgeshaped. The upper lip or gauge 70 extends downwardly and forwardly, and the lower lip or flange 71 extends upwardly and forwardly, and when the follower moves rearwardly, the upper and lower longitudinal springs are forced against the top and bottom of the draw head with great force, the friction being increased by the resiliency of the s ring bends. The inner or rear portion of t e longitudinal spring 74 is angnlarly bent to t against the angular wear plate 45 of the filler block, and' it has an ott-set or bend 78 in advance of the filler mits the spring to yield to prevent any liability of shearing the bolt 79 for securing the springs to the tiller block. Although only one bolt is shown in the accompanying '-drawin s, it will be readily understood that a plura ity of' fastening devices may be eniployed. The lower longitudinal spring T5 is provided at its rear portion with a bend 80 to permit the spring'to yield to avoid shearing'the bolt 79, and it`has a forwardly extendin arm 81 "terminating in a lip or aitge S' f and secured to the lower weai plate the front portion thereof.

In order to further increase. the friction resulting from the employment of the upper and lower longitudinal springs, the draft mechanism is equippedA with upper and lower transversely disposed' friction bars 83 wedge-shaped in cross section and located at the upper and lower faces of the draw bar. The transverse friction `bars are tapered inwardly or rearwardly and they engage' the front tapered or wedgeshaped ends 76 and 77 springs, being interposed between the saine and the draw bar, and when tlie cross bars are moved rearwardly with the draw bar, they force the front' portions of the springs outwardly, thereby increasing the tension of the sprin s and the friction produced by the same at t 1e top and bottom of the draw bar.

The upper and lower transverse friction bars are provided with reduced end portions, and the upper friction bar extends through slots the lower friction bar operates in lower recesses 86 of the draft beams. The end portions of the transverse friction bars also extend ythrough upper and lower slots H7 of the' side connecting or draw plates e8. and are equipped Aat one of the side plates with projecting lugs 89 and are perforated at and 84, tapered or the other end for the reception of keysUO.'

springs T4 and T5.-

end bottom thereof, and provided' block, which per-A of the longitudinal- 85 of the draft beams, and

"bolster, and the of the draft rigging between the draft beams and thc draft rods, and the lugs and the keys retain the ends 'of the transverse friction hars in the slots of the draw or connecting plates. The draw or connecting plates are also provided with intermediate slots 91 for the reception of the front cross head 33. By connecting the upper and lower transverse friction bars or membersv with the front cross head, they are carried rearward or inward with the draw bar.

The friction aty the top, of the draw bar tail pin and the retards the rearward movement of the draw. bar and tends to while the wedges at the opposite sides of the draw bar and sides of the follower serve to positively checkthe inward' or rearward movement rof the draw head spring 4is com letely closed or compressed.

he draw bar is supported at the .front by a carrier iron 92, which is secured at 4its terminals to the lower faces ofthe front ends of the draft parts are strengthened and reinforced by a. clamping yoke 94, embracing the draft beams at the front 9 and secured to the carrstructure at oppor# site s'ldes of the draft bars. The lsides of the cllmping yoke are secured to the draftl beams by the vfront clearly shown in Figs. 1 and 3 a't the upper edges of the..

beams by bolts 93. The" portion of the filler block I bottom and sides and at. the rear end ofthe sides of the front follower v.

absorb the shocks and jars; f

before the .coiled boiling 1 which pierce y ings. The clamping yoke and the reinforclng wear plates provide a structure charac teri'ed by great strength.

The inner or lrear'end of the -fillerblock 9 is reduced to lit the front socket 7 of the rear filler block 13, which is reinforced by a transversely dis psed wear plate 9G, tits within. the rear soc et and is provided with an opening 97 for the front end of a vguide rod 98.. The reinforcing or. wear plate 96, whichv is portions and a transverse connecting portion, is provided in the latter with an opening 99, registering` with vthe opening of the reartiller block 97. Coiled pulling springs 10() and 101, which are interposed between the rear filler block and a rear follower 10i?, are disposed on the guide rod 98. The pulling spring'lOO is larger and stronger than the spring 101, which is arranged within the spring 10th/as clearly shown in Fi s. 1 and 5 of the drawings. The rearend o rod pierces the rear follower 102, and is provided with a'hend 103. When the draw head is pulled composed -of side the guide outward, it c. tries with it""'l2*5 the draft rods 35, which move the rear cross41 being entirely coni- 13C! @salice Y l ,i pressed or closed. The rear follower is pro "viid'ed at their inner faces with integral upper and/lower approximately triangular flanges or `e-,

iilargements

105 and 106, preu "senting oppositely inclined i vand 100, '65

lower edges and forming front and rear tapering recesses.

' The upperianges or enlargements are reinforced by strengthening webs 107, disposed transversely of the upper faces of the flanges or enlargements andextending upwardly therefrom, as clearly shown. in Fig. 18 of the drawings. 4The lower llanges or enlarge ments are reinforced by' transverse ribslS, extending across the lower aces'oit the lower flanges or enlargements and the lower edges of the draft beams.

r[he tapered sides o the rear follower are i arranged in the ,rear forwardly tapered re ceases, formed by the flanges or

enlargements

105 and 106, and the rear draft beams are equipped with springs 100, each consisting ot a front approximately triangular loop 110 andrearwardly diverging upper and lower sides 111 and 112. 'Ehe'tront loop 110 is larranged in the front 'recess toi-med by the upper and`.lower flanges or enlargements 105' and 106, and-the rearwardly diverging sides 111 and 112'fare located in the rear re-y cess formed by the said langes or.enlarge ment-

s

105 and 106. The sides 111 and 112 are preferably composed of two leaves or thicknesses, and they prevent the liangesV or enlargements 105 and l'frombeing worn by the rear follower. Each spring is preterably constructed of a single strip of re silient material, which is bent .intermediate `oii its ends to forni the Atriangular loop 110.

One portion ojf the material is then extended fronnorle side of the loop to form' one of the leavesfef the lower side 100, and the material at the other side of the loop 110 isexf tended and doubled or bent back on litselfl to provide the upper side 111 and is'then extended rearwardly to form the upper leaf of the lower,` side 109' and complete c spring.- The lower side 109 is provided at its rear end with an eye 113, tormed by roll- -ing or ceiling the material and receiving a transverse bolt 114. Ylhen the springs become worn, they may bc readily'removed and replaced by new springs. The springs are held against lateral-movement on the bolt by means of .a spacing sleevell, ai'- ranged on the bolt 114 and interposedbetween the eyes 113 of the rear side springs 109. The forward tapering sides or wedges of the rear follower are limited in their forward movement by the walls of the rear recesses of the flanges Vor enlargements 105 and the outward movement of the draw head is checked befofeA the pulling ing the inward the same,

springs are completel compressed or deadened. The rear drat beams are embraced at an intermediate pointby a. rear clamping yoke 116, secured at the upper terminals of its sides to the flanges oi the,v rear draft beams. 1

ln Fig. 2e is illustrated a modification of the'invention, showing upper and lower leaf springs v117, arranged to Ypresent convex faces to a tapered follower 118, having upper and lower inclined edges or faces and 'adapted to spread or separate the @leaf springs. Thel leaf springs, which are .equipped with terminal eyes 119, are siiit- 'ably secured to a draft beam 120, and they may beI reinforced by centrally arranged coiled springs 121 interposed between the` leaf springs and upper andlower flanges 122 ofthe draft beam 120.

'libe leaf springs and the bracing coils are designed toiibe substituted for the enlarge- -ments or anges, and may be remployed in connection with either the front or rear followeii` orf-both.
